REQUEST: The applicant requests approval of a conditional use permit (CUP) to establish an Automotive Retail Sales Agency Office, and to permit the continued use of an Automotive Repair and Modification business within an existing industrial building. RECOMMENDATION: Staff recommends that the Planning Commission adopt the attached resolution, determining that this request is categorically exempt under the California Environmental Quality Act (Class 1, Existing Facilities), and approve Conditional Use Permit No. 2021-06112. BACKGROUND: The subject 8.8 acre property is developed with four single-story industrial/warehouse buildings totaling approximately 138,000 square feet. The applicant currently occupies two tenant spaces totaling approximately 5,000 square feet within the subject property. The property is located in Development Area No. 1 of the Anaheim Canyon Specific Plan (SP 2015-1), and is designated for Industrial land uses by the General Plan. The property is located approximately 650 feet west of Imperial Highway on the south side of East La Palma Avenue. The property is surrounded by the following land uses: North: Commercial, Office, and Industrial South: The Santa Ana River West: Industrial East: Commercial Retail PROPOSAL: The applicant proposes: 1) to establish an automotive retail sales agency office; and 2) to permit the continued use of an automotive repair and modification business within the existing 5,000 square foot tenant space. The existing business, 911 Vehicle, provides customized design, installation, programming and repair of intercoms, radios, computers, batteries, lights, and other technologies for emergency vehicles, command post vehicles, vans, and trailers for fire and police agencies at this location since 2012. As outlined in the Applicant’s letter of request (Attachment No. 2), a majority of the business’s contracts and sales are tied to Federal grants and purchasing cooperatives which require the vehicle and outfitting to be on a CONDITIONAL USE PERMIT NO. 2021-06112 December 6, 2021 Page 2 of 5 single contract. As such, 911 Vehicle must purchase the vehicles they are outfitting and then ship them complete to the customer. This requires the business to have a retail dealer license from the California Department of Motor Vehicles. SITE PLAN The subject business operates Monday through Thursday from 7:00 am to 6:00 pm. The business employs 11 full-time and 2 part-time technicians. Installation of equipment on the emergency vehicles takes place inside the building. There are typically 10-12 vehicles onsite at any given time for repairs or modifications. Vehicles are stored in either the building or in two fenced and secured storage yards located behind the building. Vehicles typically remain on-site for no more than 90 days. CONDITIONAL USE PERMIT NO. 2021-06112 December 6, 2021 Page 3 of 5 FLOOR PLAN FINDINGS AND ANALYSIS: Conditional Use Permit: Before the Planning Commission may approve a conditional use permit, it must make a finding of fact that the evidence presented shows that all of the following conditions exist: 1) That the proposed use is properly one for which a conditional use permit is authorized by this code; 2) That the proposed use will not adversely affect the adjoining land uses, or the growth and development of the area in which it is proposed to be located; 3) That the size and shape of the site proposed for the use is adequate to allow the full development of the proposed use, in a manner not detrimental to either the particular area or health and safety; 4) That the traffic generated by the proposed use will not impose an undue burden upon the streets and highways designed and improved to carry the traffic in the area; and 5) That the granting of the conditional use permit under the conditions imposed, if any, will not be detrimental to the health and safety of the citizens of the City of Anaheim. CONDITIONAL USE PERMIT NO. 2021-06112 December 6, 2021 Page 4 of 5 The Anaheim Municipal Code (“AMC”) permits an automotive retail sales agency office business, and an automotive repair and modification business in Development Area No. 1 of the Anaheim Canyon Specific Plan subject to approval of a CUP to ensure compatibility with the surrounding area and uses. As noted above, the subject business has been in operation at this location since 2012 with a valid business license. However, a CUP was never granted for the automotive repair and modification use. This was an oversight by the City at the time the business license was issued. Subsequently, the applicant submitted a CUP application for the retail sales agency office use. Based on review of the application and the existing use, staff asked the applicant to include the automotive repair and modification use in the CUP request. The automotive repair and modification business automotive would continue to operate as it has since 2012. The only change to the use is the addition of a retail dealer’s license as required by the DMV for the registration and sales contract with the customer. As noted above, all vehicles are stored in either the building or in two fenced and secured storage yards located behind the building. The code required parking for industrial, manufacturing, and warehouse uses on the subject site is 214 spaces. The subject property has 292 parking spaces which exceeds the code required parking. The specific code required parking for the subject automotive repair and modification use is 18 spaces. Staff has visited the property since the submittal of this application and observed that adequate parking, on-site circulation, and access are provided. It is anticipated that the continuation of the use will not have an impact on either onsite or offsite parking. Further, the facility does not have an impact on traffic and does not impose an undue burden on streets and highways in the area. The business operates compatibly with the adjoining land uses. Environmental Impact Analysis: Staff recommends that the Planning Commission find that the effects of the proposed project are Categorically Exempt from the requirements to prepare additional environmental documentation per California Environmental Quality Act (CEQA) Guidelines, Section 15301, Class 1 (Existing Facilities). The Class 1 exemption consists of the repair, maintenance, and/or minor alteration of existing public or private structures or facilities, involving negligible or no expansion of the use beyond that existing at the time of this determination. Pursuant to Section 15300.2 (c) and 15301 of Title 14 of the California Code of Regulations, there are no unusual circumstances in respect to the proposed project for which staff would anticipate a significant effect on the environment and, therefore, the proposed project would be categorically exempt from the provisions of CEQA. CONCLUSION: Based on the analysis included in this report, staff believes that the required findings can be made to approve the conditional use permit. Therefore, staff recommends that the Planning Commission adopt the Draft Resolution (Attachment No. 1) and the recommended conditions of approval contained therein and approve Conditional Use Permit No. 2021-06112.

PC2021-*** A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ANAHEIM APPROVING CONDITIONAL USE PERMIT NO. 2021-06112 AND MAKING CERTAIN FINDINGS IN CONNECTION THEREWITH (DEV2021-00164) (5604 EAST LA PALMA AVENUE) WHEREAS, the Planning Commission of the City of Anaheim (herein referred to as the "Planning Commission") did receive a verified petition to approve Conditional Use Permit No. 2021-06112 to establish an automotive retail sales agency office, and the continued use of an automotive repair and modification business within an existing industrial building (the “Proposed Project”), at a certain real property located at 5604 East La Palma Avenue in the City of Anaheim, County of Orange, State of California, as generally depicted on Exhibit A attached hereto and incorporated herein by this reference (the "Property"); and WHEREAS, the Property is approximately 8.8 acres and is currently developed with four single-story industrial/warehouse buildings totaling approximately 138,000 square feet in floor area and a surface parking area. The Property is designated for Industrial land uses by the Anaheim General Plan. The Property is also located in Development Area No. 1 of the Anaheim Canyon Specific Plan (SP 2015-1) and is subject to the zoning and development standards contained in Chapter 18.120 (Anaheim Canyon Specific Plan No. 2015-1 Zoning and Development Standards) of the Code; and WHEREAS, the Planning Commission did hold a public hearing at the Civic Center in the City of Anaheim on December 6, 2021 at 5:00 p.m. and notice of said public hearing having been duly given as required by law and in accordance with the provisions of Chapter 18.60 (Procedures) of the Code, to hear and consider evidence for and against proposed Conditional Use Permit No. 2021-06112 and to investigate and make findings and recommendation in connection therewith; and WHEREAS, pursuant to and in accordance with the provisions of the California Environmental Quality Act (Public Resources Code Section 21000 et seq.; herein referred to as “CEQA”), the State of California Guidelines for Implementation of the California Environmental Quality Act (Title 14 of the California Code of Regulations; herein referred to as the "CEQA Guidelines"), and the City's Local CEQA Procedures , the City is the "lead agency" for the preparation and consideration of environmental documents for the Proposed Project; and WHEREAS, the Planning Commission finds and determines that the effects of the Proposed Project are typical of those generated within that class of projects (i.e., Class 1 – Existing Facilities) which consist of the repair, maintenance, and/or minor alteration of existing public or private structures or facilities, involving negligible or no expansion of use beyond that existing at the time of this determination, and that, therefore, pursuant to Section 15301 of Title 14 of the California Code of Regulations, the proposed project will - 2 - PC2021-*** not cause a significant effect on the environment and is, therefore, categorically exempt from the provisions of CEQA; and WHEREAS, this Planning Commission, after due inspection, investigation and study made by itself and in its behalf, and after due consideration of all evidence and reports offered at said hearing with respect to the request for Conditional Use Permit 2021-06112, does find and determine the following: 1. The Proposed Project is an allowable use within Development Area No. 1 of the Anaheim Canyon Specific Plan (SP 2015-1) under subsection .010 of Section 18.120.040.010 (Primary Uses) of Chapter 18.120 (Anaheim Canyon Specific Plan No. 2015-1 Zoning and Development Standards) of the Code, subject to a conditional use permit and the zoning and development standards of the Anaheim Canyon Specific Plan (SP 2015-1). 2. That the proposed automotive retail sales office and automotive repair and modification business would not adversely impact adjoining industrial, warehouse, and commercial land uses because the proposed use would be less intensive than most industrial and warehouse uses in the vicinity and will not adversely affect the growth and development of the area in which it is proposed to be located, because the majority of operations would be provided inside the building. Further, the project would meet the AMC required number of parking spaces, traffic generated by the proposed use would not impose an undue burden on streets and highways in the area, and adequate on-site circulation and access would be provided. 3. That the size and shape of the site proposed for the use is adequate to allow the full development of the proposed use, in a manner not detrimental to either the particular area or health and safety because the proposed use would occupy an existing building without any expansion, and accommodate the parking, traffic flows, and circulation without creating detrimental effects on adjacent properties. 4. That the traffic generated by the proposed use will not impose an undue burden upon the streets and highways designed and improved to carry the traffic in the area because the traffic generated by this use will not exceed the anticipated volumes of traffic on the surrounding streets. 5. That the granting of the conditional use permit under the conditions imposed will not be detrimental to the health and safety of the citizens of the City of Anaheim in that any potential impacts on the surrounding uses would be minimal; and WHEREAS, this Planning Commission determines that the evidence in the record constitutes substantial evidence to support the actions taken and the findings made in this Resolution, that the facts stated in this Resolution are supported by substantial evidence in the record, including testimony received at the public hearing, the staff presentations, the staff report and all materials in the project files. There is no substantial evidence, nor are there other facts, that negate the findings made in this Resolution. This Planning Commission expressly declares that it considered all evidence presented and reached these findings after due consideration of all evidence presented to it. - 3 - PC2021-*** NOW, THEREFORE, BE IT RESOLVED that, pursuant to the above findings, this Planning Commission does hereby approve Conditional Use Permit No. 2021-06112, contingent upon and subject to the conditions of approval set forth in Exhibit B attached hereto and incorporated herein by this reference, which are hereby found to be a necessary prerequisite to the proposed use of that portion of the Property for which Conditional Use Permit No. 2021-06112 is applicable in order to preserve the health, safety and general welfare of the citizens of the City of Anaheim. Extensions for further time to complete conditions of approval may be granted in accordance with Section 18.60.170 of the Code.

DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 2 of 10 BACKGROUND: The Project Site is approximately 1.39 acres (60,548 square feet), and comprised of two parcels of land located 280 feet north of the intersection with Ball Road, on the eastern side of South Western Avenue. The Project Site is currently vacant; a single-family home and accessory garage were previously located on the Project Site. The Project Site is accessible by one existing driveway located on South Western Avenue. General Plan: The General Plan designates the Project Site for Corridor Residential land uses. The Corridor Residential designation provides for development of single-family attached townhouse style housing fronting on arterial highways on minimum one-acre sites. For projects with sufficient depth, this designation may also incorporate single family detached housing located behind the attached product. This designation is intended to provide for housing opportunities along the City’s arterial corridors. Table LU-2 of the Land Use Element of the General Plan indicates that the “RM- 1” Multiple-Family Residential Zone is the typical implementing zone for the Corridor Residential land use designation. The permitted density range is from zero up to 13 dwelling units per gross acre. The Proposed Project includes a zoning code amendment to clarify that the “RS-4” Single- Family Residential Zone may be used to implement the Corridor Residential General Plan land use designation for projects with proposed densities that are no greater than 13 dwelling units per acre. Zoning: The Project Site is within the “T” Transition Zone. The intent of the “T” Transition Zone is to provide for agricultural uses, in a transitory or interim use, restricted to limited uses because of special conditions, or not zoned to one of the zoning districts for whatever reason, including recent annexation. The Proposed Project includes a reclassification to reclassify the Project Site from the “T” Transition Zone to the “RS-4” Single Family Residential Zone. Surrounding Land Uses: Single-family residential homes surround the Project Site to the north and east and multi-family residential is adjacent to the Project Site to the south. Single-family and multi-family residential uses are located to the west across South Western Avenue. PROPOSAL: The Project would include the construction of a new 12-unit, single-family residential subdivision including one private street. The proposed lots range from 3,463 square feet to 4,336 square feet in size, with the single-family detached homes ranging from 2,314 square feet to 2,580 square feet. The Project would result in a density of 8.7 units/acre. The two-story homes would be comprised of four bedrooms, three bathrooms, and a two-car garage. Parking for two additional cars would be provided on the driveway in front of the garage. In addition, six on- street parking spaces would be provided. The buildings would range in height from approximately 25 to 29 feet, depending on the building elevation. Each lot would provide a minimum rear yard of 15.2 feet, a minimum five-foot side yard on each side of the dwelling unit, and a minimum 12- foot front yard. The Project would include front yard and streetscape landscaping throughout the proposed development. Vehicles and pedestrians would access the Project Site from Western Avenue by the proposed private street. DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 3 of 10 Design and Architecture: The units would have three floor plans with two exterior architectural design options for each floor plan. The two design options include a “Cottage” elevation and a “Spanish” elevation. Varying wall planes, rooflines, and columns articulate the front façade of each building. Each design option contains a variety of finish materials including stucco, wood, stone, clay, concrete tile, and shutters to articulate the façades along the street frontages. The Project’s use of different textures, colors, setbacks, materials, and distinctive architectural treatments creates visual interest and avoids repetitive facades consistent with the Community Design Element of the General Plan. View from Private Street Looking North DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 4 of 10 View of Lots 6 and 7 Looking West Open Space and Landscaping: Prior to construction, the Project would remove existing ornamental trees located throughout the Project Site. The Project’s proposed landscape plan would provide approximately 38 trees on-site, which includes the street trees along Western Avenue and the proposed private street. In addition, the Project, for each individual lot, would include the planting of shrubs and other ornamental landscaping. Front, side and rear private yards would provide open space for each of the residential lots. DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 5 of 10 Access, Circulation, and Parking: The proposed subdivision would include one private street, running west-east along the center portion of the subdivision, which terminates in with a “hammerhead” turnaround area at the eastern terminus. There would be one vehicular and pedestrian access point to the west-east private street from Western Avenue. A fire and sanitation truck turnaround is proposed at the eastern end of the private street. The private street would have a 36-foot paved roadway with a 6-inch raised curb. The Project design would include a four-foot wide parkway and a four-foot wide sidewalk on each side of the private street, creating pedestrian pathways throughout the subdivision. Each home would have parking for two cars in a garage and two cars on a driveway. The design of the private street would include a minimum of six parking spaces. FINDINGS AND ANALYSIS: Below is staff’s analysis and recommendations for each requested entitlement action: Zoning Code Amendment: As described previously, the General Plan designates the Project Site for Corridor Residential land use and the RM-1 Zone is the typical implementing zone for this land use designation. Pursuant to AMC Section 18.06.020, RM-1 implements the Corridor Residential land use designation and pursuant to AMC Section 18.04.020.070, the RS-4 Zone implements the Low-Medium Density Residential and Low-Medium Density Hillside land use designations. However, there is a provision in the Land Use Element that states, “In addition to the typical zoning DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 6 of 10 designations listed above, other zones may be substituted for the typical implementation zones, provided that the overall density ranges established by the General Plan are not exceeded.” The density range for the Corridor Residential designation is zero to 13.0 units per acre. The applicant is proposing to reclassify the Project Site to the “RS-4” Single-Family Residential Zone and develop the Project in accordance with the development standards of this zone. Approval of the Project would allow the construction of 12 single family detached dwellings on the 1.39- acre Project Site, which would result in a density of 8.7 units/acre. The proposed density of development is within density range established for the Corridor Residential land use designation. The proposed Zoning Code Amendment would modify Code Section 18.04.020.070 (Intent of Individual Zones) to clarify that the RS-4 Zone may be used to implement the Corridor Residential General Plan land use designation for projects with proposed densities that are no greater than 13 dwelling units per acre. Allowing the RS-4 Zone to implement the Corridor Residential land use designation will provide more flexibility in single-family detached project design and housing opportunities along the City’s arterial corridors. Reclassification: The Project Site is zoned “T” Transition. The applicant is proposing to reclassify the Project Site to the “RS-4” Single-Family Residential Zone. Pursuant to AMC Section 18.04.020.070, the intent of the “RS-4” Single-Family Residential Zone is to provide for and encourage the development of high-quality residential units on small lots, in order to provide additional housing choices and use land efficiently. The project includes the proposed Zoning Code Amendment to allow the RS-4 Zone to implement the Corridor Residential land use designation as described above. Staff supports this request because the project is designed as a small lot subdivision and would comply with the development standards of the RS-4 Zone as outlined in the table below. Zoning Consistency RS-4 Development Standards Project Minimum Lot Area Established by the site plan approved through the conditional use permit. 3,463 square feet Minimum Lot Width Established by the site plan approved through the conditional use permit. 44 feet Maximum Height 35 feet/2 stories 29’2” /2 stories Minimum Floor Area 1,225 Square feet 2,314 square feet Maximum Lot Coverage 50% 49% Setbacks Front (facing private street) 10 feet Minimum 12 feet Street Side (S.

In this zone, development standards, including minimum floor area, maximum lot coverage, and the minimum setbacks, may be modified in order to achieve a high quality project design, privacy, livability, and compatibility with surrounding uses. As outlined in the table above, the project meets all of the applicable development standards and no modifications are required. Pursuant to AMC Section 18.04.160.060 “Development in the RS-4 Zone”, before the Planning Commission may approve the conditional use permit for development in the RS-4 Zone, it must make all of the following findings. Staff believes the required findings can be made based on analysis outlined in the Draft Conditional Use Permit Resolution (Attachment 3) and described below: 1) The uses within the project are compatible: The uses within the project, specifically the single-family detached residential uses and associated improvements are compatible; 2) New buildings or structures related to the project are compatible with the scale, mass, bulk, and orientation of existing buildings in the surrounding area, provided the existing buildings conform with the provisions of this title: New buildings or structures related to the project are compatible with the scale, mass, bulk, and orientation of existing buildings in the surrounding area, including the existing single-family uses to the north, east and west; and the multi-family developments to the south and west; 3) Vehicular and pedestrian access are adequate: Vehicular and pedestrian access are adequate in that the private street, running west-east along the center portion of the subdivision would provide vehicular and pedestrian access from Western Avenue; 4) The project is consistent with any adopted design guidelines applicable to the parcel or parcels: The project is consistent with applicable design guidelines adopted by the City. The General Plan Community Design Element Policy 5.1.1 requires Design facades of residences facing arterial corridors to include richly articulated surfaces, walls, and roofline treatments. The two design options include a “Cottage” elevation and a “Spanish” elevation. Varying wall planes, rooflines, and columns articulate the front façade of each building. Each design option contains a variety of finish materials including stucco, wood, stone, clay, concrete tile, and shutters to articulate the façades along the street frontages. The Project’s use of different textures, colors, setbacks, materials, and distinctive architectural treatments creates visual interest and avoids repetitive facades; 5) The size and shape of the site proposed for the use is adequate to allow the full development of the proposed use in a manner not detrimental to the particular area: The size and shape of the site proposed for the use is adequate to allow the full development of the proposed use in a manner not detrimental to the particular area as the 1.39-acre site allows for the development of the 12-unit subdivision in compliance with the RS-4 Zone development standards; 6) The traffic generated by the proposed use will not impose an undue burden upon the streets and highways designed and improved to carry the traffic in the area: Based on the Traffic Impact Analysis prepared for the Proposed Project, the traffic generated by the proposed use is insignificant will not impose an undue DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 8 of 10 burden upon the streets and highways designed and improved to carry the traffic in the area; 7) The impact upon the surrounding area has been mitigated to the maximum extent practicable: The impact upon the surrounding area has been mitigated to the maximum extent feasible in that the project is in compliance with the RS-4 Zone development standards and is carefully designed to take into consideration the surrounding single-family and multi-family land uses and to ensure that the project would be compatible with these land uses; 8) The project complies with the General Plan and Subdivision Map Act: The project complies with the General Plan, including density range established for the Corridor Residential land use designation, and all applicable design standards. Further the project complies with all requirements of the Subdivision Map Act; and 9) The granting of the conditional use permit under the conditions imposed, if any, will not be detrimental to the health and safety of the citizens of the City of Anaheim: The project meets all applicable development standards, is compatible with surrounding uses, and subject to conditions of approval will not be detrimental to the health and safety of the citizens of the City of Anaheim. Tentative Tract Map: Pursuant to AMC Section 17.08.100 “Advisory Agency Duties” before the Planning Commission may approve the tentative tract map, it must make a finding of fact that the evidence presented shows that all of the following conditions as outlined in the Draft Tentative Tract Map Resolution (Attachment 4) exist: 1) That the proposed map is consistent with the General Plan and applicable specific plan: The proposed subdivision of the Property is consistent with the General Plan of the City of Anaheim, and more particularly with the Corridor Residential land use designation which provides for development on minimum one-acre sites for housing opportunities along the City’s arterial corridors up to 13 dwelling units per acre; 2) That the design or improvement of the proposed subdivision is consistent with the General Plan and applicable specific plan: The proposed design and improvements of the subdivision is consistent with the General Plan of the City of Anaheim including street and utility improvements; 3) That the site is physically suitable for the type of development: The proposed subdivision of the Property, as shown on proposed Tentative Tract Map No. 17944, including its design and improvements, is consistent with the zoning and development standards of the “RS-4” Single-Family Residential Zone proposed; 4) That the site is physically suitable for the proposed density of development: The site is physically suitable for the type and density of the Proposed Project in that the 1.39 acre site allows for the development of the 12-lot small lot subdivision in compliance with the RS-4 Zone development standards; 5) That the design of the subdivision or the proposed improvements are not likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat: The design of the subdivision, as shown on proposed Tentative Tract Map No. 17944, is not likely to cause substantial environmental DEVELOPMENT PERMIT NO. 2019-00139 910 South Western Avenue December 6, 2021 Page 9 of 10 damage or substantially and avoidably injure fish or wildlife or their habitat, as no sensitive environmental habitat has been identified; 6) That the design of the subdivision or type of improvements are not likely to cause serious public health problems: The design of the subdivision, as shown on proposed Tentative Tract Map No. 17944 or the proposed improvements is not likely to cause serious public health problems; and 7) That the design of the subdivision or the type of improvements will not conflict with easements, acquired by the public at large, for access through or use of, property within the proposed subdivision: The design of the subdivision, as shown on proposed Tentative Tract Map No. 17944, or the proposed improvements will not conflict with easements acquired by the public, at large, for access through or use of property within the proposed subdivision. A tentative tract map is proposed to create a 12-unit subdivision for 12 detached single-family homes. The proposed density of 8.7 dwelling units per acre complies with the Corridor Residential land use designation which provides for development on minimum one-acre sites for housing opportunities along the City’s arterial corridors up to 13 dwelling units per. In addition, the project does not conflict with easements acquired by the public and complies with all subdivision requirements. Therefore, staff recommends approval of the tentative tract map request. Community Outreach and Correspondence: The applicant held a community outreach meeting, on Nov. 16, 2021 at the Brookhurst Community Center. A meeting notice was sent to all addresses within a 500-foot radius of the project. Two neighbors attended the meeting. The applicant answered their questions and addressed any concerns. The applicant has provided a summary of the community outreach meeting (Attachment 6). As of the date of this staff report, no additional correspondence has been received. Environmental Impact Analysis: The Project qualifies for a Class 32 – In-Fill Development Project Categorical Exemption under the California Environmental Quality Act (CEQA) (Public Resources Code, Sections 21000-21189.57) as set forth in Section 15332 of the State CEQA Guidelines (California Code of Regulations, Title 14, Chapter 3, Sections 15000-15387). Based on the analysis in the CEQA Class 32 Categorical Exemption Environmental Checklist (Attachment 7) staff recommends that the Planning Commission determine that the Project will not cause a significant effect on the environment and is, therefore, categorically exempt from the requirement for the preparation of environmental documents under the California Environmental Quality Act and no further environmental review is required. CONCLUSION: Staff has carefully considered the Proposed Project and believes that it is compatible with surrounding single-family and multi-family land uses and designed in a manner to provide a quality living environment for its future residents while at the same time creating enhanced streetscape amenities along Western Avenue for the surrounding community. In addition, the Proposed Project meets the goals of the General Plan to provide residential opportunities along the City’s arterial corridors, and to provide a variety of quality housing opportunities to address the City’s diverse housing needs. Therefore, staff recommends approval of the Project.

Western Avenue Class 32 Exemption Project Description Page II-1 I. PROJECT DESCRIPTION 1. ENVIRONMENTAL SETTING a) Project Location The Project is located at 910 Western Avenue, Anaheim, CA 92804 in the City of Anaheim (the “City”) and is associated with the following Assessor Parcel Numbers (the “Project Site”): 079- 882-36 and 079-882-37. The Project Site is approximately 1.39 acres (60,548 square feet), exclusive of the required dedications, and comprised of two parcels of land located 280 feet north of the intersection with Ball Road, on the eastern side of Western Avenue (see Figures I-1, Regional Vicinity and Project Location Map and I-2, Aerial View of Project Site). Regional vehicular access to the Project Site includes State Route 91 (SR-91) (Riverside Freeway), with access via Beach Boulevard, approximately 2.57 miles north of the Project Site. Western Avenue and Ball Road provide local access to the Project Site. b) Existing Conditions The Project Site is currently vacant; a single-family home and accessory garage were previously located on the Project Site. The Project Site is accessible by one existing driveway located on Western Avenue. See Figure I-3, Views of the Project Site. The General Plan designates the Project Site for Corridor Residential land use. The Corridor Residential designation provides for development on minimum one-acre sites for single-family attached townhouse style housing fronting on arterial highways. Table LU-2 of the Land Use Element of the General Plan indicates that the “RM-1” Multiple-Family Residential Zone is the typical implementing zone for the Corridor Residential land use designation is the RM-1 Zone. The permitted density range is from zero up to 13 dwelling units per gross acre. The Project Site is within the “T” Transition Zone. The intent of the “T” Transition Zone is to provide for a zone to include land for agricultural uses, in a transitory or interim use, restricted to limited uses because of special conditions, or not zoned to one of the zoning districts for whatever reason, including recent annexation. The Project is subject to the approval of a Zoning Code amendment to allow the “RS-4” Single- Family Residential Zone to implement the Corridor Residential General Plan land use designation, a zoning reclassification from “T” Transition Zone to “RS-4” Single-Family Residential Zone, and the approval of a conditional use permit and a subdivision tract map.1 1 Anaheim Municipal Code, Section 18.04.020. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption I. Project Description Page I-2 c) Surrounding Land Uses Single-family residential homes surround the Project Site to the north and east and multi-family residential is adjacent to the Project Site to the south. Across from the Project Site, to west along Western Avenue, are single-family and multi-family residential uses. Figures I-4 and I-5 provide views of the surrounding land uses. 2. PROJECT CHARACTERISTICS a) Project Overview The Project includes the construction of a new 12-unit, small lot single-family residential subdivision including one private street. The Project is located in the “T” Transition Zone and the use is subject to the approval of a zoning code amendment, zoning reclassification, conditional use permit, and subdivision tract map. The proposed lots range from 3,463 square feet to 4,336 square feet in size with single-family detached homes ranging from 2,314 square feet to 2,580 square feet. The Project would result in a density of 8.7 units/acre. The two-story homes would be comprised of four bedrooms, three bathrooms, and a two car garage. There would be available parking for two additional cars on the adjacent driveway. In addition, there would be six on-street parking spaces provided. The buildings would range in height from approximately 25 to 29 feet, depending on the building elevation. Each lot would provide a minimum rear yard of 15.2-feet, a minimum five-foot side yard on each side of the dwelling unit, and a minimum 12-foot front yard. The Project would include front yard and streetscape landscaping across the proposed development. Vehicles would access the property from a private street from Western Avenue. All service vehicles for the community, such as trash and deliveries, would access the Project Site through the private street. Figures I-6 through I-9 depict the Project’s floor plans. As described previously, the General Plan designates the Project Site for Corridor Residential land use and the RM-1 Zone is the typical implementing zone for this land use designation. However, there is a provision in the Land Use Element that states, “In addition to the typical zoning designations listed above, other zones may be substituted for the typical implementation zones, provided that the overall density ranges established by the General Plan are not exceeded.” The density range for the Corridor Residential designation is zero to 13.0 units per acre. The applicant is proposing to reclassify the Project Site to the “RS-4” Single-Family Residential Zone and develop the Project in accordance with the development standards of said zone. Approval of the Project would allow the construction of a new 12-unit, small lot single-family residential subdivision including one private street on a 1.39-acre Project Site, which would result in a density of 8.7 units/acre. The proposed density of development is within density range established for the Corridor Residential land use designation. The Project would include a City-initiated Zoning Code Amendment to modify Code Section 18.04.020 (Intent of Individual Zones) to clarify that in addition to the RM-1 Zone, the RS-4 Zone City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption I. Project Description Page I-3 may be used to implement the Corridor Residential General Plan land use designation for projects with proposed densities that are no greater than 13 dwelling units per acre. In order to permit development of the Project, the City would require approval of the following discretionary actions: (1) Zoning Reclassification to reclassify the Project Site from the “T” Transition Zone to the “RS-4” Single Family Residential Zone; (2) Conditional Use Permit to allow development of 12 Single-Family Detached Dwellings; and (3) Subdivision Tract Map to permit a 12-unit small lot subdivision. In addition, the City would process the following request concurrently with the above discretionary actions: (1) Zoning Code Amendment City-initiated request to amend Anaheim Municipal Code Section 18.04.020 (Intent of Individual Zones) to clarify that the “RS-4” Single-Family Residential Zone may be used to implement the Corridor Residential General Plan land use designation for projects with proposed densities that are no greater than 13 dwelling units per acre. This amendment would resolve an inconsistency between the General Plan and the Zoning Code that staff identified with the Project The Project would potentially require other ministerial permits and approvals, including, but not limited to, temporary street closure permits, demolition permits, grading permits, excavation/shoring permits, building permits, and sign permits in order to fully execute and implement the Project.

Project Description Page I-13 b) Design and Architecture The Project has three floor plans with two exterior architectural design options for each floor plan. The two design options include a “Cottage” elevation and a “Spanish” elevation. Varying wall planes, rooflines, and columns articulate the front façade of each building. Each design option contains a variety of finish materials including stucco, wood, stone, clay, concrete tile, and shutters to articulate the façades along the street frontages. The Project’s use of different textures, colors, setbacks, materials, and distinctive architectural treatments creates visual interest and avoids repetitive facades consistent with the Community Design Element of the General Plan. See Figures I-10 through I-16 for the Project’s elevations and conceptual renderings, found at the end of Section 2. Project Characteristics. c) Open Space and Landscaping Prior to construction, the Project would remove existing ornamental trees located throughout the Project Site. The Project’s proposed landscape plan would provide approximately 38 trees on-site, which includes the street trees along Western Avenue and the proposed private street. In addition, the Project would plant each individual lot with shrubs and other ornamental landscaping. Front, side and rear private yards would provide open space for each of the residential lots. See Figure I-17 for the Project’s landscape plans (found at the end of Section 2. Project Characteristics). d) Access, Circulation, and Parking The subdivision includes one private street, running west-east along the center portion of the subdivision, which terminates in with a “hammerhead” turnaround area at the eastern terminus. There would be one vehicular and pedestrian access point to the west-east private street from Western Avenue. There would be a fire and sanitation truck turn around at the eastern end of the private street. The private street would have a 36-foot paved roadway with a 6-inch raised curb. The Project design includes a four-foot wide parkway and a four-foot wide sidewalk on each side of the private streets, creating pedestrian pathways throughout the subdivision. Each home would have parking for two cars in a garage and two cars on a driveway. The design of the private street would include a minimum of six parking spaces. e) Sustainability Features The Project would be compliant with the California Energy Code/Title 24 requirements, and would include, but not be limited to, the following features: • Low-flow faucets, shower heads, and toilets; • Energy efficient mechanical systems; • Energy efficient glazing and window frames; and • Energy efficient lighting. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption I. Project Description Page I-14 f) Anticipated Construction Schedule The Applicant anticipates constructing the Project over approximately 12 months. Construction activities would include the demolition of the existing pavement, grading, and building construction. The applicant anticipates that demolition activities would start in the first quarter of 2023, and construction completion and occupancy would occur in the first quarter of 2024. The Project would cut 880 cubic yards of soil and import 77 cubic yards for a total then of 957 cubic yards of earthwork material to occur on-site. Any exported materials would be disposed at one of the County’s operating inert landfills (Olinda Alpha, Frank R. Bowerman, and Prima Deshecha). The City would review the Project’s haul route as part of its review of the Project’s grading permit. 3.

PROJECT ANALYSIS Condition (a): The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. a) Land Use and Planning 1) City of Anaheim General Plan The City of Anaheim General Plan (General Plan) guides land use throughout the City. The General Plan sets forth goals, objectives, and programs to guide day-to-day land use policies and to meet the existing and future needs and desires of the community, while integrating a range of State-mandated elements including Land Use, Circulation, Green Element, Public Services, Growth Management, Safety, Noise, Economic Development, Community Design, and Housing. The Land Use Element of the General Plan consists of nine community policy areas that guide land use at a neighborhood level. The Project Site is located within the West Anaheim Area, which is designated as a redevelopment area. The City has initiated commercial and residential redevelopment projects, extensive outreach with West Anaheim stakeholders, detailed market studies, corridor landscape programs, and neighborhood improvement programs, among others.2 The General Plan designates the Project Site for Corridor-Residential land use. The Corridor Residential designation provides for development on minimum one-acre sites for single-family attached townhouse style housing fronting on arterial highways. The typical implementing zone for the Corridor Residential land use designation is the “RM-1” Multiple-Family Residential Zone. The permitted density range is from zero up to 13 dwelling units per gross acre.3 Table II-1, Project Consistency with the General Plan presents an analysis between the applicable goals and policies in the General Plan. As shown, the Project would be consistent with the applicable goals and policies. Table II-1 Project Consistency with the General Plan Goal/Policya Project Consistency Land Use Element Goal 1.1: Preserve and enhance the quality and character of Anaheim’s mosaic of unique neighborhoods.

Policy 2.1.1: Facilitate new residential development on vacant or underutilized infill parcels. Consistent: The Project would develop a new 12-unit, small lot single-family residential subdivision on an underutilized site on Western Avenue that was previously developed with a single family residence. Policy 2.1.6: Ensure quality development through appropriate development standards and by adherence to related Community Design Element policies and guidelines. Consistent: The Project would incorporate high quality, permanent building materials and would comply with Community Design Element policies and guidelines, as discussed below under the Community Design Element heading. Goal 3.1: Pursue land uses along major corridors that enhance the City’s image and stimulate appropriate development at strategic locations. Consistent: The Project would develop a new 12-unit, small lot single-family residential subdivision on an underutilized site on Western Avenue. Thereby, promoting the corridor-residential land use designation. Goal 4.1: Promote development that integrates with and minimizes impacts to surrounding land uses. Consistent: The Project is directly adjacent to residential uses to the north, east, and south, and provides rear setbacks ranging from 15’2” to 16’7”. Though the Project would be comprised of a subdivision development on a currently vacant lot, the proposed setback would provide sufficient separation of the uses and would minimize impacts to the surrounding residential uses. Policy 4.1.1: Ensure that land uses develop in accordance with the Land Use Plan and Zoning Code in an effort to attain land use compatibility. Consistent: The Anaheim Municipal Code (Code) establishes the zoning for the Project Site, which is “T” Transition. With the approval of a CUP the zoning would be reclassified to RS-4, which allows for the 12- unit small lot subdivision. With the approval of the CUP the Project would be consistent with this policy and a compatible use within the immediate area of the Project Site. Policy 4.1.2: Promote compatible development through adherence to Community Design Element policies and guidelines. Consistent: The Project’s use of different textures, colors, setbacks, materials, and distinctive architectural treatments, are designed to create visual interest, avoid repetitive facades, consistent with the Community Design Element. Refer to the Community Design Element heading, below. Policy 4.1.3: Ensure that developers consider and address project impacts upon surrounding neighborhoods during the design and development process. Consistent: The Project Site is relatively flat and is immediately surrounded by multi- and single-family residential land uses in an urban setting that is similar to other areas in Anaheim. The Project’s two-story homes would be consistent with the single-family homes in the immediate area. The building heights and massing that would be developed with the implementation of the Project would be compatible with the character of the surrounding area.

Policy 4.1.4: Require new or expanded uses to provide mitigation or buffers between existing uses where potential adverse impacts could occur. Consistent: The Project would provide a minimum of 5’-foot side yard setbacks and rear setbacks ranging from 15’2” to 16’7”, which are adjacent to residential uses, thus creating buffers to the immediate neighboring uses. The existing south side property line wall would remain, and additional trees and landscaping would be provided under future project conditions. In addition, there would be additional landscaping with trees along the eastern property line, along with a new block wall on the north and east property lines to provide additional buffer from the adjacent residential uses. Community Design Element Policy 5.1.1: Design facades of residences facing arterial corridors to include richly articulated surfaces, walls, and roofline treatments. Consistent: The two design options include a “Cottage” elevation and a “Spanish” elevation. Varying wall planes, rooflines, and columns articulate the front façade of each building. Each design option contains a variety of finish materials including stucco, wood, stone, clay, concrete tile, and shutters to articulate the façades along the street frontages. The Project’s use of different textures, colors, setbacks, materials, and distinctive architectural treatments creates visual interest and avoids repetitive facades. Policy 5.1.4: In addition to porches, require that each dwelling unit have a reasonable amount of usable private open space (e.g., elevated decks, terraces and rear yards. Consistent: Each lot would maintain a minimum rear yard of 15’2” feet thereby creating private open space in the rear of each unit. Policy 5.1.6: Where alley loading is not feasible, minimize curb cuts by incorporating shared driveways and locating parking behind residences. Consistent: The subdivision includes one private no through street in the location of the original driveway of the Project Site and running west-east along the center portion of the subdivision. Thereby, creating one vehicular access point to the west-east private street from Western Avenue. Policy 5.1.7: Place parkway street trees at regular intervals to buffer residential uses and create a unifying visual element along the arterial corridor. Consistent: The Project’s landscape plan would include a variety of trees, shrubs, and ground cover. Approximately 38 trees would be planted on the Project Site, of which six trees would be street trees, planted along Western Avenue. Policy 5.1.8: Require a minimum landscaped setback between the sidewalk and the front yard fence to provide more privacy for residents and allow for an additional row of trees and landscaping. Consistent: The Project would provide a minimum of 10-foot front yard setback, along with 32 trees planted throughout the front yards of each unit.

Policy 11.1.2: Encourage architectural designs that are visually stimulating and varied, yet tasteful, containing rich contrasts and distinctive architectural elements. Consistent: Refer to Policy 5.1.1 above. Policy 11.1.3: Ensure that the scale, materials, style and massing of new development is consistent with its surroundings and any larger vision for an area. Consistent: Though the scale and massing are similar to the single-family residences surrounding the site. The two types of design include hip and gable roof lines that are typically of residential structures versus the flat roof lines that are typical of commercial buildings. The Project design includes extensive use of architectural details. The overall design would be consistent with the surrounding area. Policy 11.1.4: Add visual richness to residential streets by discouraging the same building elevations on adjacent lots and avoiding repetitious elements and colors. Consistent: Two floor plans are proposed, along with two architectural designs for each of the floor plans. The proposed building facades would be articulated and use a range of architectural elements, including varied texture, materials, and color. Policy 11.1.5: Encourage energy and environmental efficiency – such as “Green Development Standards” (see Green Element) – in the design and approval of new projects. Consistent: The Project would be compliant with the California Energy Code/Title 24 requirements, and would include, but not be limited to, the following features: low-flow faucets, shower heads, and toilets; energy efficient mechanical systems; energy efficient glazing and window frames; and energy efficient lighting. Green Element Goal 7.1: Reduce urban run-off from new and existing development. Consistent: The Project Site does not currently operate under a Standard Urban Storm Water Mitigation Plan (SUSMP). As such, implementation of the Project with a SUSMP would improve water quality on the Project Site compared to existing conditions. Further, as detailed in the Preliminary Hydrology Report prepared for the Project, the Project proposes a stormdrain treatment consisting of infiltration treatment via permeable pavement that would not adversely affect the downstream facilities or neighborhood.4 Policy 7.1.1: Ensure compliance with the Federal Clean Water Act requirements for National Pollutant Discharge Elimination Consistent: In accordance with the requirements of NPDES permit, the Project would implement a Stormwater Pollution Prevention Plan that specifies 4 Refer to Appendix D, Preliminary Hydrology Report for Tract 17944, City of Anaheim, Orange County, prepared by Mayers & Associates Civil Engineering, Inc., September 2021.

Best Management Practices and erosion control measures during construction to manage runoff flows and prevent pollution. In addition, in accordance with NPDES Municipal Permit requirements, the Project would be required to implement Standard Urban Stormwater Mitigation Plan and Low Impact Development requirements throughout the operational life of the Project. The Standard Urban Stormwater Mitigation Plan would outline and require stormwater treatment measures or post-construction Best Management Practices to control pollutants of concern Policy 7.1.4: Require new development and significant redevelopment to utilize site preparation, grading and best management practices that provide erosion and sediment control to prevent construction-related contaminants from leaving the site and polluting waterways. Consistent: The Project would be required to obtain coverage under the National Pollutant Discharge Elimination System Construction General Permit. In accordance with the requirements of this permit, the Project would implement a Stormwater Pollution Prevention Plan that specifies the implementation of Best Management Practices and erosion control measures during construction to manage runoff flows and prevent pollution. Policy 8.1.2: Regulate construction practices, including grading, dust suppression, chemical management, and encourage pre-determined construction routes that minimize dust and particulate matter pollution. Consistent: South Coast Air Quality Management District’s (SCAQMD) Rule 403 minimum requirements require the application of the best available dust control measures for all grading operations and include the application of water or other soil stabilizers in sufficient quantity to prevent the generation of visible dust plumes. Compliance with Rule 403 would require the use of water trucks during all phases where earth moving operations would occur.

The Zoning Code includes development standards for the various districts in the City. The Zoning Code establishes the underlying zoning for the Project Site, which is “T” Transition Zone. The intent of the “T” Transition Zone is to provide for a zone to include land that is used for agricultural uses, in a transitory or interim use, restricted to limited uses because of special conditions, or not zoned to one of the zoning districts for whatever reason, including recent annexation. The “Small Lot Single-Family Residential Subdivision” land use is a permitted use within the “T” Transition Zone, City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-7 subject to the approval of a conditional use permit, zoning reclassification from “T” Transition Zone to “RS-4” Single-Family Residential Zone, and the approval of a subdivision tract map.5 The applicant is proposing to reclassify the Project Site to the “RS-4” Single-Family Residential Zone and develop the Project in accordance with the development standards of said zone. Approval of the Project would allow the construction of a new 12-unit, small lot single-family residential subdivision including one private street on a 1.39-acre Project Site, which would result in a density of 8.7 units/acre. The proposed density of development is within density range established for the Corridor Residential land use designation. The Project would also include a City-initiated Zoning Code Amendment to modify Code Section 18.04.020 (Intent of Individual Zones) to clarify that in addition to the RM-1 Zone, the RS-4 Zone would also implement the Corridor Residential General Plan land use designation for projects with proposed densities that are no greater than 13 dwelling units per acre. The Project is consistent with the development standards of both RS-4 as explained below in Table II-2, Zoning Consistency.

The State developed CALGreen, and mandates that local jurisdictions adopt CALGreen, to attain consistency among the various jurisdictions within the State with the specific goals to reduce a building’s energy and water use, reduce waste, and reduce the carbon footprint. The following types of projects are subject to the Green Building Code: • All new buildings (residential and non-residential); • Every building alteration with a building permit valuation of $200,000 or more (residential and non-residential); • Residential alterations that increase the building’s conditioned volume; and, • Every building addition (residential and non-residential). The Project would be compliant with the California Energy Code/Title 24 requirements, and would include, but not be limited to, the following features: • Low-flow faucets, shower heads, and toilets; • Energy efficient mechanical systems; • Energy efficient glazing and window frames; and • Energy efficient lighting. (a) Summary As discussed above, with the approval of above referenced zoning reclassification, CUP, and subdivision tract map, the Project would be consistent with its general plan designation and all applicable general plan policies, as well as, with its zoning designation and regulations. Condition (b): The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses. The Project Site is located entirely within the City limits on a site that is approximately 60,548 square feet (1.39-acre) in size. Figures I-1 through I-5 in Section I, Project Description show views of the Project Site and its regional vicinity; as shown therein, the Project Site is located in an urbanized setting characterized by residential uses. As such, the Project meets this condition. Condition (c): The project site has no value as habitat for endangered, rare or threatened species. a) Conservation Plans The City encompasses a variety of open space and natural areas that serve as habitat for sensitive species. Portions of the City of Anaheim are within the Orange County Central/Coastal Natural Communities Conservation Plan Subregion (NCCP) and Habitat Conservation Plan (HCP).6 The 6 Anaheim General Plan/Zoning Code Update EIR, May 2004. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-9 NCCP/HCP provides for the protection of a number of plant and animal species, referred to as target species and identified species, and considered sensitive. The Project Site is not located within the NCCP or the HCP. Regardless, a background search and literature review was conducted of existing biological resources data within the Project footprint, including a 500-foot buffer surrounding the site.7 The review focused on special-status plant and wildlife species and sensitive habitat types identified using the following databases: Google Earth, the California Department of Fish and Wildlife’s California Natural Diversity Database (CNDDB), the California Native Plant Society (CNPS) Rare Plant Inventory (RPI), National Wetland Inventory (NWI), and U.S. Fish and Wildlife Service’s Information for Planning and Consultation (IPaC) trust resource report. The CNDDB and NWI query included the project footprint and a one-mile buffer. The CNPS RPI query consisted of an eight-quadrangle search around the Project area; a nine-quadrangle search was not completed as CNPS treats the Long Beach and Long Beach OE S 7.5-minute USGS quadrangles as a single quadrangle. This search resulted in lists of potentially occurring biological resources, compiled from these queries.8 These results include special status plant and wildlife species (including state or federally listed as rare, threatened, endangered, species of special concern, or unique species) and natural communities. 1) CNDDB and USFW IPaC Special Status Wildlife Results of the CNDDB and IPaC queries indicated five special-status wildlife species known to occur within the one-mile search area (refer to Appendix A of this document). These include the California Least Tern (Sterna antillarum browni), the Western Snowy Plover (Charadruis nivosus nivos), the Coastal California gnatcatcher (Polioptila californica californica), the Pacific Pocket Mouse (Perognathus longimembris pacificus), and the Western tidal-flat tiger beetle (Habroscelimorpha gabbii). 9 These species require specialized habitat such as coastal sage scrub and coastal environments including open beaches, mudflats, sand dunes, sand spits, lagoons, estuaries, salt marshes, dredged material deposal sites, salt pond levees, dry salt ponds, river alluvium, and river bars, which are not present within Project Site. While no suitable habitat for these five special-status wildlife species is present within the Project Site and 500-foot buffer area, suitable nesting habitat for raptors and native migratory bird species protected by California Fish and Game Code 3503.5 and the Migratory Bird Treaty Act (MBTA) is present within the Project Site. While no additional mitigation measures would be required, the Project would be required to comply with these existing federal and State laws (i.e., MBTA and California Fish and Game Code, respectively). The Project Site is surrounded by residential development which suggests human activity in the area is high, resulting in a low likelihood that wildlife species sensitive to human disturbance would be present in or use the study area. The Project Site and surrounding area is anticipated to 7 Refer to Appendix A, Biological Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, July 30, 2021. 8 Refer to Appendix A, Biological Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, July 30, 2021, Appendix A and B. 9 Refer to Appendix A, Biological Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, July 30, 2021, Appendix A.

Categorical Exemption Analysis Page II-10 support wildlife species that thrive in urban and disturbed habitats, including but not limited to, California ground squirrel (Otospermophilus beecheyi), raccoon (Procyon lotor), American crow (Corvus brachyrhynchos), European starling (Sturnus vulgaris), northern mockingbird (Mimus polyglottos), lesser goldfinch (Carduelis psaltria), rock pigeon (Columba livia), house finch (Passer domesticus), and western fence lizard (Sceloporus occidentalis). 2) CNPS and RPI Special Status Plants Results of the CNPS RPI query indicated 26 special-status plant species known to occur within the eight-quad search area. However, the Biological Constraints Desktop Review (refer to Appendix A of this document), concluded that none of these species would occur on the Project Site.10 The study area consists of developed and landscaped areas that do not support habitat suitable for special status plant species. Therefore, Project activities would not affect special status plant habitat. 3) NWI Wetland Features Results of the NWI query indicated one wetland feature is present within the one-mile search radius. Carbon Creek is located approximately 0.35 miles northwest of the Project. Carbon Creek is an intermittent creek with an artificial streambed that does not contain suitable habitat for special status species. This creek connects with the Los Alamitos, a man-made channel, which connects with San Pedro Bay.11 However, compliance with the California Water Boards Construction Stormwater Program, as discussed below under subheading (e) Project-Specific Water Quality Impacts, would result in less than significant impacts to Carbon Creek and all downstream connecting bodies of water. 4) Summary Due to the developed and landscaped nature of the Project Site and surrounding area, no suitable habitat that would support special-status plant or wildlife species, or sensitive habitats protected by California Department of Fish and Wildlife (CDFW), is present. The Project Site and its vicinity are not part of any draft or adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan.12 However, there are several ornamental trees growing within the Project Site boundaries, which would be removed during construction. None of these trees are protected species by the City’s tree protection ordinance; however, these trees may provide temporary suitable habitat for nesting migratory birds, which are protected under the federal MBTA. The MBTA, which is an international treaty ratified in 1918, protects migratory nongame native bird species (as listed in 50 C.F.R. Section 10.13) and their nests. Additionally, Section 3503, 3503.5, and 3513 of the California Fish and Game Code prohibit take of all birds and their active nests, including raptors 10 Refer to Appendix A, Biological Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, July 30, 2021, Appendix B. 11 Refer to Appendix A, Biological Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, July 30, 2021. 12 California Department of Fish and Wildlife, California Regional Conservation Plans, April 2019. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-11 and other migratory nongame birds (as listed under the MBTA). Tree removals would be undertaken pursuant to applicable City permits and requirements. The Project would be required to comply with these existing federal and State laws (i.e., MBTA and California Fish and Game Code, respectively). Additionally, the Project would include at least 38 trees, which would increase the Project Site’s potential for usage by migratory or nesting birds. The Project would not result in any significant impacts in regards to habitat for endangered, rare, or threatened species, the Project meets this condition. Condition (d): Approval of the project would not result in any significant effects related to traffic, noise, air quality, greenhouse gases, or water quality. The following provides a Project-specific analysis of the impacts to traffic, noise, air quality, greenhouse gases, and water quality. a) Project-Specific Transportation Impacts Refer to Appendix B – Traffic Impact Analysis and Appendix C - VMT Assessment, regarding new/updated information in the Final Traffic Impact Analysis and VMT Assessment. The following transportation impact analysis summarizes and incorporates by reference the information provided in the Revised Traffic Impact Analysis for the Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021 (Impact Assessment) and the Final Vehicle Miles Traveled Assessment for the Proposed Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, September 2021 (Trip Generation Assessment). The Traffic Impact Anaysis and VMT Assessment are available as Appendix B and Appendix C to this document. 1) Project Trip Generation Forecast Comparison The amount of one-way vehicular movement, either entering or exiting the generating land use, referred to as “vehicle trip ends,” determines the number of trips generated for a project. Traffic generation rates used in traffic forecasting procedures are found in the ITE Trip Generation Manual; the ITE Trip Generation Manual, 10th Edition published by the Institute of Transportation Engineers (ITE) [Washington, D.C., 2017], was utilized to forecast these results. The Project is forecast to generate approximately 113 daily trips, with 9 trips (2 inbound, 7 outbound) produced in the AM peak hour and 12 trips (8 inbound, 4 outbound) produced in the PM peak hour on a “typical” weekday.13 The City of Anaheim has adopted Level of Service policies in the City of Anaheim General Plan. These policies set standards for which local transportation infrastructure will strive to maintain. Pursuant to SB 743, the analysis of Level of Service will no longer be a part of a project’s CEQA analysis. However, because the City of Anaheim General Plan contains Level of Service Policies, the City will continue to apply these General Plan policies. Per the City of 13 Refer to Appendix B, Revised Traffic Impact Analysis for the Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021, Table 5-1.

Categorical Exemption Analysis Page II-12 Anaheim threshold criteria, as a minimum, intersections where the Project would add 51 (i.e., 3% of 1,700) or more trips during either AM or PM weekday peak hours need to be studied. As a result, based on the nominal AM and PM peak hour trip generation increase with the Project (i.e. < 50 peak hour trips), the Project would not significantly impact the surrounding transportation system.14 2) Project Trip Generation Assessment The State of California defines the Project as a Single-Family Residential development.15 Under the Traffic Impact Analysis (TIA) Guidelines for CEQA - VMT, developed by the City of Anaheim in compliance with CEQA, project screening can determine if a project would be required to conduct a detailed VMT analysis. As such, the following guidance summarizes the potential project screening, developed for the City of Anaheim: Type 1: Transit Priority Area (TPA) Screening Pursuant to CEQA Guidelines Section 15064.3, “Determining the Significance of Transportation Impacts” Subsection (b)(1) states in part: “Generally, projects within one-half mile of either an existing major transit stop or a stop along an existing high quality transit corridor should be presumed to cause a less than significant transportation impact.” Pursuant to the statute, development projects may be screened out of VMT analysis based on proximity to certain transit facilities due to the presumption of less than significant impacts. The Technical Advisory reiterates this screening criteria, but also highlights certain project-specific or location-specific characteristics which may indicate the project will still generate “significant levels of VMT”, even when located within one-half mile of a major transit stop or a stop along a high-quality transit corridor. These characteristics relate to the project’s floor area ratio (FAR), parking supply, and number of dwelling units, as well as consistency with the applicable Sustainable Communities Strategy (SCS). If the project has any characteristics which indicate that the presumption of less than significant impacts as stated in the CEQA Guidelines may not be appropriate, the OPR Technical Advisory recommends that the project should not be screened out of further VMT analysis. The City of Anaheim has a developed a TPA map, which was utilized to determine whether this Project can be screened out based on the TPA criteria. 1. Has a total Floor Area Ratio (FAR) of less than 0.75; 2. Includes more parking for use by residents, customers, or employees of the project than required by the jurisdiction (if the jurisdiction requires the project to supply parking); 14 The threshold criteria is outlined in the City of Anaheim Criteria For Preparation of Traffic Impact Studies. 15 Refer to Appendix C, Final Vehicle Miles Traveled Assessment for the Proposed Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, September 2021, for specific criteria. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-13 3. Is inconsistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Metropolitan Planning Organization); or 4. Replaces affordable residential units with a smaller number of moderate- or high- income residential units. Based on the above, the Project will not screen-out under this criteria since while the Project Site is within the TPA, the Project Floor Area Ratio is less than 0.75.16 Type 2: Low VMT Area Screening An additional screening methodology is provided for residential and office land use projects. Lead agencies may prepare maps based on a regional travel demand model or travel survey data to illustrate areas that are currently below the selected VMT threshold. OPR reasons that if a project has similar characteristics to the existing area (i.e., density, mix of uses, transit service, etc.), it would tend to exhibit similar VMT. Therefore, if a project is fully located within an area identified as having a below-threshold VMT, it may be presumed to also have less than significant VMT impacts and be screened out from requiring a detailed VMT analysis. The City of Anaheim has a developed a map showing low VMT-generating zones as compared to the County, which was utilized to determine whether this Project can be screened out based on the low VMT-generating area criteria. In addition, the Project must be consistent with the existing land use within that TAZ. Therefore, a review was conducted to confirm that the Project land use is consistent with the existing land use within the Orange County Transportation Analysis Model (OCTAM). The Project is located in the OCTAM traffic analysis zone (TAZ) 350.17 Therefore, the Project would screen-out under this criterion since it is located within a low VMT- generating area (<15% below the Orange County Average)18 and the Project is consistent with the existing land use in the TAZ, which is primarily residential. 3) Site Access and On-Site Circulation Evaluation The Project access is forecast to operate at LOS C or better during the AM and PM peak hours under Year 2022 Cumulative Plus Project traffic conditions. As such, Project access would be adequate. Motorists entering and exiting the Project Site would be able to do so without undue congestion. The on-site circulation layout of the Project as illustrated in Figure II-1 on an overall basis is adequate. Curb return radii are generally adequate for small service/delivery (FedEx, UPS) trucks and trash trucks.19 The on-site circulation layout of the Project on an overall basis is adequate. 16 Attachment A of the City of Anaheim Traffic Impact Analysis Guidelines for CEQA Analysis, June 2020. 17 Refer to Appendix C, Final Vehicle Miles Traveled Assessment for the Proposed Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, September 2021, refer to Table 1. 18 Attachment B of the City of Anaheim Traffic Impact Analysis Guidelines for CEQA Analysis, June 2020. 19 Refer to Appendix B, Revised Traffic Impact Analysis for Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021.

Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-15 4) Transportation Impact Summary As indicated above, the Project would result in less than significant impacts to traffic. Therefore, as the Project Site would not result in any significant effects related to traffic, the Project meets this condition for traffic. b) Project-Specific Noise Impacts Noise is typically defined as a sound that is loud, unpleasant, unexpected, or otherwise undesirable and is described in terms of a sound’s amplitude (loudness), frequency (pitch), or duration (time). The ambient noise environment is comprised of stationary and mobile noise sources. Sound dissipates exponentially with distance from the noise source. This phenomenon is known as “spreading loss.” For a single point source, sound levels decrease by approximately 6 dB for each doubling of distance from the source. This drop-off rate is appropriate for noise generated by on- site operations from stationary equipment or activity at a project site. If noise is produced by a line source, such as highway traffic, the sound decreases by 3 dB for each doubling of distance in a hard site environment. Line-source noise in a relatively flat environment with absorptive vegetation decreases by 4.5 dB for each doubling of distance.20 The physical measure of sound, or sound level, is in decibels (dB), based on a logarithmic scale. Therefore, a doubling of the energy of a noise source, such as doubling of traffic volume, would increase the noise level by 3 dB; a halving of the energy would result in a 3 dB decrease. Everyday sounds normally range from 30 dB (very quiet) to 100 dB (very loud). The A-weighted decibel scale relates noise to human sensitivity. The “A-weighted decibel”, abbreviated dBA, is the measurement used for common noise levels. Table II-3, Typical Noise Levels, provides examples of various noises and their typical A-weighted noise level.

Although human perception of sound is somewhat subjective, it is widely accepted that the average healthy ear (1) can barely perceive an increase or decrease of 3 dBA; (2) can perceive a change of 3 dBA in outdoor environments; and (3) can notice that an increase of 10 dBA sounds twice as loud. Noise, or sound over a period of time, can be measured using a number of methods. The two most common methods are the community noise equivalent (CNEL) and the equivalent sound level (Leq). dBA Leq is the term for measurement of the average noise levels over a period of minutes or hours. The CNEL scale represents the average of 24-hourly noise measurements and adjusts or penalizes the dBA during certain sensitive time periods to account for increased noise sensitivity during the evening and nighttime periods. The evening time period (7:00 PM to 10:00 PM) penalizes noises by 5 dBA, while nighttime (10:00 PM to 7:00 AM) noises are penalized by 10 dBA. 1) Regulatory Setting (a) State of California Title 24 of the California Code of Regulations, also known as the California Building Standards Code, establishes building standards applicable to all occupancies throughout the state. Section 1207.11.2 requires that the design of residential structures, other than detached single-family dwellings, prevent the intrusion of exterior noise so that the interior noise attributable to exterior sources shall not exceed 45 dBA CNEL in any habitable room. Section 1207.12 states, “if interior allowable noise levels are met by requiring that windows be inoperable or closed, the design for the structure must also specify a ventilation or air-conditioning system to provide a habitable interior requirement. The ventilation system must not compromise the dwelling unit or guest room noise reduction.” City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-17 (i) City of Anaheim City of Anaheim General Plan The City has adopted the State of California’s exterior noise and land use compatibility standards for land use development in the Noise Element of its General Plan, as shown in Table II-4, Land Use Compatibility for Community Noise Exposure. These Guidelines establish standards for outdoor noise levels that are acceptable, conditionally acceptable, and unacceptable for a variety of land uses. For industrial uses, noise levels of up to 75 dBA CNEL are “normally acceptable.” Noise environments with noise levels up to 80 dBA CNEL are “conditionally acceptable”; under this circumstance, the City may permit the development only after detailed analysis of the noise reduction requirements and needed noise insulation features are included in the project design. Conventional construction, but with closed windows and a fresh air supply system or air conditioning, would normally suffice as a noise insulation feature for these conditionally acceptable environments. These standards apply to the Project itself. The City of Anaheim General Plan contains goals and policies that address noise. The following General Plan goals and policies are applicable to the Project: • Goal 1.1: Protect sensitive land uses from excessive noise through diligent planning and regulation. • Goal 2.1: Encourage the reduction of noise from transportation-related noise sources such as motor vehicles, aircraft operations, and railroad movements. o Policy 3: Require that development generating increased traffic and subsequent increases in the ambient noise level adjacent to noise-sensitive land uses provide appropriate mitigation measures. • Goal 3.1: Protect residents from the effects of “spill over” or nuisance noise emanating from the City’s activity centers. o Policy 1: Discourage new projects located in commercial or entertainment areas from exceeding stationary-source noise standards at the property line of proximate residential or commercial uses, as appropriate. o Policy 2: Prohibit new industrial uses from exceeding commercial or residential stationary-source noise standards at the most proximate land uses, as appropriate. (Industrial noise may spill over to proximate industrial uses so long as the combined noise does not exceed the appropriate industrial standards.) o Policy 3: Enforce standards to regulate noise from construction activities. Particular emphasis shall be placed on the restriction of the hours in which work other than emergency work may occur. Discourage construction on weekends or holidays except in the case of construction proximate to schools where these operations could disturb the classroom environment. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-18 o Policy 4: Require that construction equipment operate with mufflers and intake silencers no less effective than originally equipped. o Policy 3: Encourage the use of portable noise barriers for heavy equipment operations performed within 100 feet of existing residences or make applicant provide evidence as to why the use of such barriers is infeasible. In the City of Anaheim General Plan Noise Element, the City adopted land use-noise compatibility standards shown in Table II-4, Land Use Compatibility for Community Noise Exposure. Table II-4 Land Use Compatibility for Community Noise Exposure (Exterior)1 Land Use Community Noise Exposure dBA CNEL or Ldn 55 60 65 70 75 Normally Acceptable: Specified land use is satisfactory based upon the assumption that any buildings involved are of normal conventional construction, without any special noise insulation requirements. Conditionally Acceptable: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is made and needed noise insulation features included in the design. Conventional construction, but with closed windows and fresh air supply systems or air conditioning would normally suffice. Outdoor environment would seem noisy. Normally Unacceptable: New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made with needed noise insulation features included in the design. Outdoor areas must be shielded. Clearly Unacceptable: New construction or development should generally not be undertaken. Construction cost to make the indoor environment acceptable would be prohibitive and the outdoor environment would not be usable.

Schools, libraries, churches, hospitals, single and multiple-family residential, including transient lodging, motels and hotel uses make up the majority of these types of areas. A residential neighborhood with single-family uses surrounds the Project Site. Sensitive land uses that may be affected by project noise include: directly east, north and south of the site, and ~80 feet east of the site (across S. Western Avenue). To identify existing noise conditions, four short-term (10-minute) noise levels were measured in the vicinity of the Project Site. Figure II-2, Noise Measurement Location Map depicts the locations of the noise measurements. EcoTierra Consulting (“Consultant”) conducted the noise survey on August 17, 2021 between 1:41 PM and 3:42 PM using the Larson Davis Sound Track LxT2 sound level meter, which conforms to industry standards set forth in ANSI S1.4-1983 (R2006) – Specification for Sound Level Meters/Type 1 and meets the requirements set forth in City of Anaheim municipal code 6.70.010. The Consultant calibrated and operated the instrument according to the manufacturer’s written specifications. At the measurement sites, the Consultant placed the microphone at a height of approximately five feet above grade. At the time of the noise measurements, there was hazy sunshine; and the temperature was 83 degrees Fahrenheit with 10 mph wind conditions and approximately 55 percent humidity. As shown on Figure II-2, Noise Measurement Location Map, the Consultant took the noise measurements near the closest residential uses to: the west, west of S. Western Avenue and north of Ball Road (NM1); to the south, adjacent to the southern boundary of the site on the eastern side of S. Western Avenue (NM2); to the north, adjacent to the northern boundary of the site and south of W. Teranimar Drive (NM3); and to the east, at the closest residential uses located at the end of the cul-de-sac of W. Glen Holly Drive (NM4). Table II-5, Existing Ambient Noise Levels, provides a summary of the ambient noise data. Ambient average noise levels were between 48.1 and 73.4 dBA Leq. Appendix F to this document includes photos, field sheet, and measured noise data. The dominant noise sources were from vehicles traveling along the adjacent roadways, pedestrians, residential ambiance (music playing, wind chimes etc.), helicopters and other aircraft.

Ambient noise data details are available in Appendix F to this document. 3) Construction Noise The Applicant expects construction of the Project to last approximately 12 months and require the use of heavy equipment. The Applicant anticipates that the construction phases for the Project would include demolition, site preparation, grading, building construction, paving, and architectural coating. During each construction phase there would be a different mix of equipment operating and noise levels would vary based on the amount of equipment in operation and the location of each activity. As stated above, the nearest sensitive receptors that could potentially be subject to noise impacts associated with demolition/construction of the Project include residential uses directly north, east and south of the Site, and approximately 80 feet west of the site (across S. Western Avenue). However, any increase in noise levels at off-site receptors during construction of the Project would be temporary in nature, and would not generate continuously high noise levels, although occasional single-event disturbances from construction are possible. In addition, the construction noise during the heavier initial periods of construction (i.e., demolition and site preparation work) would City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-26 typically be reduced in the later construction phases (i.e., interior building construction at the proposed building) as the physical structure of the proposed structure would break the line-of-sight noise transmission from the construction area to the nearby sensitive receptors. As shown in Table II-5 above, sensitive receptors in the area are already exposed to maximum (Lmax) noise levels up to 92.1 dBA. A summary of noise level data for a variety of construction equipment compiled by the Federal Highway Administration (FHWA) is available in Appendix F of this document. Typical operating cycles for these types of construction equipment may involve one or two minutes of full power operation followed by three to four minutes at lower power settings. Noise levels associated with each phase of construction were modeled utilizing worksheets based on the FHWA Roadway Construction Noise Model (RNCM), together with several key construction parameters including: distance to each sensitive receiver, equipment usage, percent usage factor, and baseline parameters for the Project Site. This analysis bases distances to receptors on the acoustical center of the proposed construction activity, and calculated the construction noise levels for each phase. To be conservative, the noise generated by each piece of equipment was added together for each phase of construction; however, it is unlikely (and unrealistic) that every piece of equipment would be used at the same time, at the same distance from the receptor, for each phase of construction. Table II-6, Construction Noise Levels (by Phase) at Nearest Receptors provides a summary of anticipated noise levels during each construction phase at the closest receptors; and worksheets are included as Appendix F to this document.

(2) Construction noise calculation details available in Appendix F. Note: Noise levels from construction activities do not take into account attenuation afforded by intervening structures or topography. As shown in Table II-6 above, construction noise levels could reach up to 76.6 dBA during the noisiest phase (demolition) at the residential receptors closest to the southern boundary of Project Site (NM2), located on the eastern side of S. Western Avenue and north of Ball Road. Construction equipment would operate throughout the Project site during each phase and the associated noise levels would not occur at a fixed location for extended periods. The Project will disperse construction noise throughout the project site and roadway noise will mask much of the construction noise. The City’s Noise Ordinance does not establish quantitative construction noise standards. The FTA has established a daytime threshold of 90 dBA Leq (1 hour) for residential uses 100 dBA Leq (1 hour) for nonresidential uses to evaluate construction noise impacts.21 As shown by the results report in Table II-6, noise levels at the closest sensitive receptor locations would be well below 90 dBA. Although construction noise would have a temporary or periodic increase in the ambient noise levels above the existing levels within the project vicinity, the Code requires construction to occur between 7:00 a.m. and 7:00 p.m. Sound created by construction is exempt from the Code standards during this period. Therefore, with compliance with City noise regulations, construction noise impacts would be less than significant. 4) Operational Noise (a) Stationary Noise Sources Mechanical equipment (e.g., heating, ventilation, and air conditioning [HVAC] equipment) typically generates noise levels of approximately 52 dBA at 50 feet.22 Sound levels decrease by 6 21 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, Table 7-2, Page 179, September 2018. 22 Elliott H. Berger, Rick Neitzel1, and Cynthia A. Kladden. (2010). Noise Navigator Sound Level Database with Over 1700 Measurement Values. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-28 dBA for each doubling of distance from the source.23 The façade of the nearest noise-sensitive receptor is anticipated to be no closer than 15 feet from the closest potential proposed dwelling unit. At 15 feet, mechanical equipment noise levels would be 62.5 dBA. However, according to the site plan (dated December 22, 2020) the HVAC unit looks to be located at ground level, and would be shielded by 6-foot-tall cinder block wall. The block wall would reduce the noise level from the HVAC unit by at least 5 dBA, which would reduce the noise level down to 57.5 dBA at the nearest noise-sensitive receptor. Therefore, the noise level would be below the City’s 60 dBA exterior noise standard set forth in AMC §6.70.0110. Impacts from mechanical equipment would be less than significant. (b) Traffic Noise In order for a new noise source to be audible, there would need to be a three dBA or greater CNEL noise increase. The traffic volume on any given roadway would need to double in order for a three dBA increase in ambient noise to occur. 24 Per the traffic study,25 the greatest increase in Project traffic volume would be 20 vehicles and the existing plus cumulative plus project traffic average daily traffic volume26 would range between 7,520 vehicles to 10,090 vehicles per day along the segments of Orange Avenue, Ball Road and Western Avenue.27 Therefore, as the highest Project- related increase in traffic along road segments within a ¼ mile of the Project Site would not result in any audible increase in traffic noise generated by the Project, traffic noise-related impacts would be considered less than significant. (c) Airport-Related Noise The nearest airport is Fullerton Municipal Airport, located approximately 3.68 miles northeast of the Project Site. As such, air traffic noise from Fullerton Municipal Airport would not be a source that contributes to the ambient noise levels on the project site. Therefore, impacts are less than significant. 5) Noise Impact Summary The Project would not result in any significant noise impacts during the construction and operations phases. c) Project-Specific Air Quality Impacts This checklist has evaluated the Project to determine if it would violate an air quality standard or contribute to an existing or projected air quality violation. Additionally, this analysis evaluated the Project to determine if it would result in a cumulatively considerable net increase of a criteria 23 Cyril M.

The significance of these potential impacts is below. 1) Standards of Significance The SCAQMD has developed significance thresholds for regulated pollutants, as summarized in Table II-7, SCAQMD Air Quality Significance Thresholds. The SCAQMD’s CEQA Air Quality Significance Thresholds (April 2019) indicate that any projects in the SCAB with daily emissions that exceed any of the indicated thresholds should be considered as having an individually and cumulatively significant air quality impact. The SCAQMD also provides a threshold for emissions of lead; however, this analysis did not calculate lead emissions because a) that is not a pollutant that is analyzed in CalEEMod, b) lead emissions were mainly sourced from vehicle emissions, but lead has been banned for use in fuel for new vehicles since 1996 and have been banned in residential paints since 1978, and c) Orange County is in both state and federal attainment for lead, so lead is not a pollutant of concern for air quality emissions in Anaheim. So yes, the project will not be a substantive sources of lead emissions. Additionally, the air quality- modeling program (discussed below) does not calculate any emissions of lead from typical construction or operational activities.

The SCAQMD developed CalEEMod in collaboration with the air districts of California.28 Regional data (e.g., emission factors, trip lengths, meteorology, source inventory, etc.) from the various California air districts accounts for local requirements and conditions. The model is an accurate and comprehensive tool for quantifying air quality impacts from land use projects throughout California and recommended for use in CEQA documents by the SCAQMD.29 The analysis forecasts daily regional emissions during construction by assuming a conservative estimate of construction activities (i.e., assuming all construction occurs at the earliest feasible date) and applying the mobile source and fugitive dust emissions factors. The analysis adjusts the input values used to be project-specific for the construction schedule and, uses CalEEMod defaults for the construction equipment that the Project would use. The CalEEMod program uses the EMFAC2017 computer program to calculate the emission rates specific for Orange County for construction-related employee vehicle trips and the OFFROAD2011 computer program to calculate emission rates for heavy truck operations. EMFAC2017 and OFFROAD2011 are computer programs generated by California Air Resources Board (CARB) that calculates composite emission rates for vehicles. The program reports emission rates in either grams per trip and grams per mile, or grams per running hour. The analysis uses daily truck trips and CalEEMod default trip length data to assess roadway emissions from truck exhaust. The maximum daily emissions are estimated values for the worst-case day and do not represent the emissions that would occur for every day of project construction. The analysis then compares maximum daily emissions to the SCAQMD daily regional numeric indicators. Detailed construction equipment lists, construction scheduling, and emission calculations are available in the CalEEMod Output provided in Appendix G of this document. 28 SCAQMD. website: http://www.aqmd.gov/caleemod/, accessed September 2021. 29 South Coast Air Quality Management District, California Emissions Estimator Model.

Categorical Exemption Analysis Page II-31 Construction activities associated with the Project would result in emissions of VOCs, NOX, SOX, CO, PM10, and PM2.5 from the following construction activities: • Demolition • Site Preparation • Grading • Building Construction • Paving • Architectural Coating The Applicant expects construction to start no sooner than the first quarter of 2023 (January) and take approximately 12 months. The construction schedule utilized in the analysis represents a “worst-case” analysis scenario even if construction was to occur any time after the respective dates since emission factors for construction decrease as time passes and the analysis year increases due to emission regulations becoming more stringent.30 The construction activities for the Project are anticipated to include: demolition of approximately 12,000 square feet (SF) of existing paving/swimming pool, site preparation and grading of approximately 1.39 acres, construction of 12 single-family dwelling units (with a maximum square footage of 2,580 each; for a total of 30,960 SF), paving of approximately 0.36 acres of on-site roads, and application of architectural coatings. Approximately 77 cubic yards (CY) of dirt would be imported during grading. Dust is typically a major concern during demolition, site preparation and rough grading activities. Because such emissions are not amenable to collection and discharge through a controlled source, they are “fugitive emissions”. Fugitive dust emissions rates vary as a function of many parameters (soil silt, soil moisture, wind speed, area disturbed, number of vehicles, depth of disturbance or excavation, etc.). CalEEMod calculated fugitive dust emissions resulting from this phase of activity. The Project would be required to comply with existing SCAQMD rules for the reduction of fugitive dust emissions. SCAQMD Rule 403 establishes these procedures. The Project would comply with this rule through application of standard best management practices in construction and operation activities. These activities include the application of water or chemical stabilizers to disturbed soils, managing haul road dust by application of water, covering haul vehicles, restricting vehicle speeds on unpaved roads to 15 mph, sweeping loose dirt from paved site access roadways, cessation of construction activity when winds exceed 25 mph and establishing a permanent, stabilizing ground cover on finished sites. In addition, projects that disturb 50 acres or more of soil or move 5,000 cubic yards of materials per day are required to submit a Fugitive Dust Control Plan or a Large Operation Notification Form to SCAQMD. Based on the size of the 30 As shown in the California Emissions Estimator Model (CalEEMod) User’s Guide Version 2020.4.0, Section 4.3 “OFFROAD Equipment” as the analysis year increases, emission factors for the same equipment pieces decrease due to the natural turnover of older equipment being replaced by newer less polluting equipment and new regulatory requirements.

Categorical Exemption Analysis Page II-32 Project area (approximately 1.39 acres) a Fugitive Dust Control Plan or Large Operation Notification would not be required. SCAQMD’s Rule 403 minimum requirements require that the application of the best available dust control measures is used for all grading operations and include the application of water or other soil stabilizers in sufficient quantity to prevent the generation of visible dust plumes. Compliance with Rule 403 would require the use of water trucks during all phases where earth-moving operations would occur; the emissions modeling assumes that the project would comply with Rule 403. CalEEMod estimated construction emissions for construction worker vehicles traveling to and from the Project Site, as well as vendor trips (construction materials delivered to the Project site). SCAQMD Rules that are currently applicable during construction activity for this Project include but are not limited to Rule 1113 (Architectural Coatings) and Rule 403 (Fugitive Dust). The analysis considers these Best Available Control Measures (BACMs) as standard regulatory requirements and provides credit for Rule 403 and Rule 1113.

As shown in Table II-8, Construction-Related Regional Pollutant Emissions, emissions resulting from the Project construction would not exceed criteria pollutant thresholds established by the SCAQMD for emissions of any criteria pollutant. Thus, a less than significant impact would occur for Project-related construction-source emissions. (a) Localized Significance-Construction The SCAQMD has established that impacts to air quality are significant if there is a potential to contribute or cause localized exceedances of the federal and/or state ambient air quality standards (NAAQS/CAAQS). Collectively, these are localized significance thresholds (LSTs). The significance of localized emissions impacts depends on whether ambient levels within 500 meters (0.31 miles) of any given project are above or below State standards. In the case of CO and NO2, if ambient levels are below the standards, a project has a significant impact if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a state or federal standard, then project emissions are significant if they increase ambient concentrations by a measurable amount. This would apply to PM10 and PM2.5; both of which are non-attainment pollutants. The SCAQMD established LSTs in response to the SCAQMD Governing Board’s Environmental Justice Initiative I-4. LSTs represent the maximum emissions from a project that would not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard at the nearest residence or sensitive receptor. The SCAQMD states that lead agencies can use the LSTs as another indicator of significance in its air quality impact analyses. To address the issue of localized significance, the SCAQMD adopted LSTs that show whether a project would cause or contribute to localized air quality impacts and thereby cause or contribute to potential localized adverse health effects. The analysis makes use of methodology included in the SCAQMD Final Localized Significance Threshold Methodology (LST Methodology). SCAQMD’s Methodology clearly states, “Off-site mobile emissions from the Project should NOT be included in the emissions compared to LSTs.”31 Therefore, for purposes of the construction 31 South Coast Air Quality Management District, Localized Significance Thresholds Methodology, 2005. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-34 LST analysis, this analysis only considers emissions included in the CalEEMod “on-site” emissions outputs. The land uses immediately surrounding the Project Site include: the residential uses directly east, north and south of the site, and ~80 feet east of the site (across S. Western Avenue). According to LST Methodology, “any receptor located closer than 25 meters (82 feet) shall be based on the 25- meter thresholds.” The Project Site is approximately 1.39 acres and the nearest sensitive receptors to the Project Site include the residential uses adjacent to the site; therefore, the analysis used SCAQMD Look-up Tables for 1 acre at a distance of 25 meters. Other air quality sensitive land uses are located further from the Project Site and would experience lower impacts. Table II-9, Local Construction Emissions at the Nearest Receptors, shows the on-site emissions from the CalEEMod model for the different construction phases and the LST emissions thresholds.

No No No No a The nearest sensitive receptors to the project include: the residential uses directly east, north and south of the site, and ~80 feet east of the site (across S. Western Avenue); therefore, the 25 meter threshold was used. Source: Calculated from CalEEMod and SCAQMD’s Mass Rate Look-up Tables for 2 acres at a distance of 25 m in SRA 17 Central Orange County. The data provided in Table II-9, Local Construction Emissions at the Nearest Receptors, shows that none of the analyzed criteria pollutants would exceed the local emissions thresholds at the nearest sensitive receptors. Therefore, a less than significant local air quality impact would occur from construction of the Project. 3) Operational Emissions Operational activities associated with the Project would result in emissions of VOCs, NOX, SOX, CO, PM10, and PM2.5 from the following primary sources: • Area Source Emissions • Energy Source Emissions • Mobile Source Emissions (a) Area Source Emissions Architectural Coatings: Over a period of approximately 10 days the buildings that are part of this Project would be subject to emissions resulting from the evaporation of solvents contained in City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-35 paints, varnishes, primers, and other surface coatings as part of Project maintenance. Rule 1113 (Architectural Coatings) limits paints applied to buildings to 50g/L VOC content. Consumer Products: Consumer products include, but are not limited to detergents, cleaning compounds, polishes, personal care products, and lawn and garden products. Many of these products contain organic compounds which when released in the atmosphere can react to form ozone and other photochemically reactive pollutants. Fireplaces: The Project is not proposing to install any wood-burning fireplaces; and therefore, does not result in any emissions associated with any wood-burning hearths/fireplaces. CalEEMod defaults estimates that 90 percent of the homes will have fireplaces. Landscape Maintenance Equipment: Landscape maintenance equipment would generate emissions from fuel combustion and evaporation of unburned fuel. Equipment in this category would include lawnmowers, shredders/grinders, blowers, trimmers, chain saws, and hedge trimmers used to maintain the landscaping of the Project. (b) Energy Source Emissions Combustion Emissions Associated with Natural Gas and Electricity: Most projects have criteria pollutant emissions emitted through the generation of electricity and consumption of natural gas. Anaheim Public Utilities’ power supply comes from resources located in Anaheim and across the Western United States.32 (c) Source Emissions Vehicles: Project mobile source air quality impacts are dependent on both overall daily vehicle trip generation and the effect of the Project on peak hour traffic volumes and traffic operations in ¼ mile of the Project. The Project-related operational air quality impacts are primarily from vehicle trips generated by the Project. According to the project-specific traffic analysis (TIA)33, the Project would generate 113 daily trips. Using the trip generation rates from the TIA, the Project would generate 9.44 daily trips/DU. CalEEMod defaults were used for the Saturday and Sunday trip generation rates. The CalEEMod program then applies the emission factors for each trip, provided by the EMFAC2017 model, to determine the vehicular traffic pollutant emissions. Fugitive Dust Related to Vehicular Travel: Vehicles traveling on paved roads would be a source of fugitive emissions due to the generation of road dust inclusive of tire wear particulates. (d) Emissions Summary The analysis included the potential operations-related air emissions for the criteria pollutants and cumulative impacts. The analysis calculated the worst-case summer or winter criteria pollutant 32 City of Anaheim Public Utilities, About Electric Service, website: https://www.anaheim.net/2104/About-Electric- Services, accessed September 2021. 33 Refer to Appendix B, Revised Traffic Impact Analysis for the Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-36 emissions created from the Project’s long-term operations, which are below in Table II-10, Regional Operational Pollutant Emissions.

No No No No No No a Area sources consist of emissions from consumer products, architectural coatings, and landscaping equipment. b Energy usage consists of emissions from generation of electricity and on-site natural gas usage. c Mobile sources consist of emissions from vehicles and road dust. Source: CalEEMod Version 2020.4.0; the higher of either summer or winter emissions, available in Appendix G. The results from Table II-10, Regional Operational Pollutant Emissions, show that the Project does not exceed the SCAQMD regional thresholds. Therefore, a less than significant regional air quality impact would occur from operation of the Project. No mitigation measures are required. 4) Localized Significance – Operation Project-related air emissions from on-site sources such as architectural coatings, landscaping equipment, onsite usage of natural gas appliances as well as the operation of vehicles on-site may have the potential to exceed the state and federal air quality standards within 500 meters (0.31 miles of the Project Site. However, these pollutant emissions may not be significant enough to create a regional impact to the Air Basin. The nearest sensitive receptors to the Project Site include: the residential uses directly east, north and south of the site, and ~80 feet east of the site (across S. Western Avenue). According to SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes stationary sources (such as mining sites, boilers, power-generating plants, etc.), or attracts mobile sources (such as heavy-duty trucks) that may spend long periods queuing and idling at the site; such as industrial warehouse/transfer facilities. The Project involves the construction and operation residential uses. Due the lack of on-site/stationary source emissions, the Project does not warrant a long-term localized significance threshold analysis. Therefore, the Project’s contribution to cumulative regional emissions would not be considerable and, thus, would be less than significant. 5) Toxic Air Contaminants Some people are especially sensitive to air pollution and require special consideration when evaluating air quality impacts from projects. These groups of people include children, the elderly, and individuals with pre-existing respiratory or cardiovascular illness, and athletes and others who engage in frequent exercise. AQMD defines “sensitive receptors” to be to be a receptor such as City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-37 residence, hospital, convalescent facility where it is possible that an individual could remain for 24 hours. The nearest sensitive receptors to the Project Site include: the residential uses directly east, north and south of the site, and ~80 feet east of the site (across S. Western Avenue).34 (a) Construction With respect to TACs, the greatest potential for TAC emissions resulting from construction of the Project would involve diesel particulate emissions associated with trucks and heavy equipment. Based on SCAQMD guidance, health effects from TACs are usually described in terms of individual cancer risk, which is the likelihood that a person exposed to TACs over a 70-year lifetime would contract cancer. Project construction activity would not result in long-term substantial sources of TAC emissions (i.e., 30 or 70 years) and would not generate ongoing construction TAC emissions. Given the temporary and short-term construction schedule (approximately 12 months), the Project would not result in a long-term (i.e., lifetime or 30-year) exposure because of Project construction. Furthermore, as shown above, construction-based particulate matter (PM) emissions (including diesel exhaust emissions) do not exceed any local or regional thresholds. In addition, the construction activities associated with the Project would be similar to other development projects in the City, and would be subject to the regulations and laws relating to toxic air pollutants at the regional, State, and Federal level that would protect sensitive receptors from substantial concentrations of these emissions. The Project would be consistent with applicable AQMP requirements for control strategies intended to reduce emissions from construction equipment and activities. The Project would comply with the CARB Air Toxics Control Measure that limits diesel powered equipment and vehicle idling to no more than five (5) minutes at a location, and the CARB In-Use Off-Road Diesel Vehicle Regulation; compliance with these regulations would minimize emissions of TACs during construction. The Project would also comply with the requirements of SCAQMD Rule 1403 in the event that the demolition activities discover asbestos. (b) Operation In an urban setting, vehicle exhaust is the primary source of CO. Consequently, the highest CO concentrations are generally close to congested intersections. Under typical meteorological conditions, CO concentrations tend to decrease as the distance from the emissions source (e.g., congested intersection) increases. Therefore, for purposes of providing a conservative worst-case impact analysis, CO concentrations the analysis typically includes congested intersection locations. If the analysis finds that impacts are less than significant close to congested intersections, impacts also would be less than significant at more distant sensitive-receptor and other locations. The Transportation Project-Level Carbon Monoxide Protocol (CO Protocol) provides an initial screening procedure to determine whether a project poses the potential to generate a CO hotspot.35 The key criterion is whether the Project would worsen traffic congestion at signalized intersections operating at level of service (LOS) E or F. If a project poses a potential 34 AQMD, website: http://www.aqmd.gov/docs/default-source/ceqa/handbook/localized-significance- thresholds/final-lst-methodology-document.pdf?sfvrsn=2, accessed September 2021. 35 UC Davis, Institute of Transportation Studies, 1997. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-38 for a CO hotspot, a quantitative screening is required. Per the TIA prepared for the Project, implementation of the Project would not worsen traffic at any of the analyzed signalized intersections operating at LOS E or F.36 Therefore, the impact would be less than significant. 6) Odors Odors are typically associated with the use of chemicals, solvents, petroleum products, and other strong-smelling elements used in manufacturing processes. According to the SCAQMD CEQA Air Quality Handbook, land uses and industrial operations that are associated with odor complaints include agricultural uses, wastewater treatment plants, food-processing plants, chemical plants, composting, refineries, landfills, dairies and fiberglass molding. The Project involves the construction and operation of single-family dwelling units, which are not typically associated with odor complaints. Potential sources that may emit odors during construction activities include the application of materials such as asphalt pavement. Objectionable odors produced during the construction process are short-term in nature and would cease upon the drying or hardening of the odor producing materials. Due to the short-term nature and limited amounts of odor producing materials, no significant impact related to odors would occur during construction of the Project. The Project would result in the emission of diesel exhaust and VOCs during construction, which would be objectionable to some; however, emissions would disperse rapidly from the Project Site and therefore should not reach an objectionable level at the nearest sensitive receptors. As the Project involves no operational elements related to industrial projects, there would be no long-term operational objectionable odors. Therefore, potential impacts associated with objectionable odors would be less than significant. 7) AQMP Consistency The City, including the Project Site, is within the South Coast Air Basin (Basin), and the SCAQMD is directly responsible for reducing emissions from stationary (area and point), mobile and indirect sources to meet federal and State ambient air quality standards. The SCAQMD has responded to this requirement by preparing a series of AQMPs. The 2016 AQMP identifies the implementation of control measures over a 20-year horizon to reduce major sources of pollutants. Control measures established in previous AQMPs have substantially decreased exposure to unhealthful levels of pollutants, even while substantial population growth has occurred within the Basin. The 2016 AQMP continues to evaluate current integrated strategies and control measures to meet the National Ambient Air Quality Standards (NAAQS), as well as explore new and innovative methods to reach its goals. Some of these approaches include utilizing incentive programs, recognizing existing co-benefit programs from other sectors, and developing a strategy with fair- share reductions at the federal, state, and local levels.37 36 Refer to Appendix B, Revised Traffic Impact Analysis for the Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021. 37 South Coast Air Quality Management District. Final 2016 Air Quality Management Plan (AQMP), March 2017. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-39 Criteria for determining consistency with the AQMP are in Chapter 12, Section 12.2 and Section 12.3 of the SCAQMD’s CEQA Air Quality Handbook (1993). These indicators are below: Consistency Criterion No. 1: The Project would not result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations, or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP. (a) Construction Impacts The violations that Consistency Criterion No. 1 refers to are the California Ambient Air Quality Standards (CAAQS) and NAAQS. CAAQS and NAAQS violations would occur if the Project exceeds localized significance thresholds (LSTs) or regional significance thresholds. The Project would not exceed the applicable LSTs or regional significance thresholds for construction activity. Therefore, the Project would not conflict with the AQMP according to this criterion. (b) Operational Impacts The Project would not exceed the applicable LST or regional significance thresholds for operational activity. Therefore, the Project would not conflict with the AQMP according to this criterion. Based on the preceding discussion, the Project is consistent with the first criterion. Consistency Criterion No. 2: The Project would not exceed the assumptions in the AQMP based on the years of Project build-out phase. (c) Overview The 2016 AQMP demonstrates that the applicable ambient air quality standards can be achieved within the timeframes required under federal law. Growth projections from local general plans adopted by cities in the district are provided to the SCAG, which develops regional growth forecasts, which are then used to develop future air quality forecasts for the AQMP. Development consistent with the growth projections in City General Plan is considered to be consistent with the AQMP. (d) Construction Impacts Peak day emissions generated by construction activities are largely independent of land use assignments, but rather are a function of development scope and maximum area of disturbance. Irrespective of the Site’s land use designation, development of the site to its maximum potential would likely occur, with disturbance of the entire site occurring during construction activities. (e) Operational Impacts As stated previously, the General Plan designates the Project Site for Corridor Residential land use and the RM-1 Zone is the typical implementing zone for this land use designation. The density range for the Corridor Residential designation is 0 to 13.0 units per acre. The applicant is proposing to reclassify the Project Site to the “RS-4” Single-Family Residential Zone and develop the Project in accordance with the development standards of said zone. Approval of the Project would allow the construction of a new 12-unit, small lot single-family residential subdivision City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-40 including one private street on a 1.39-acre Project Site, which would result in a density of 8.7 units/acre. The proposed density of development is within density range established for the Corridor Residential land use designation. Therefore, the development proposed by the Project would be consistent with regional growth projections and consistent with the AQMP. As further discussed above, the Project would not exceed regional or local thresholds and would have a less than significant impact. Based on the preceding discussion, the Project is determined to be consistent with the second criterion. (f) AQMP Consistency Conclusion The Project would not result in or cause NAAQS or CAAQS violations. The Project would not result in any construction-source or operational-source emissions exceedances. The Project is therefore consistent with the AQMP. Thus, the Project would not conflict with or obstruct implementation of the AQMP, and this impact would be less than significant. 8) Air Quality Impact Summary As explained in detail in above subsections, the Project would not result in any significant effects relating to air quality. d) Project-Specific Greenhouse Gas Impacts Greenhouse gases (GHG) are those gaseous constituents of the atmosphere, both natural and human generated, that absorbs and emits radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the earth’s surface, the atmosphere itself, and by clouds. GHGs, as defined under California’s Assembly Bill (AB) 32, include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). General discussions on climate change often include water vapor, atmospheric ozone, and aerosols in the GHG category. Water vapor and atmospheric ozone are not gases that are formed directly in the construction or operation of development Projects, nor can they be controlled in these Projects. Aerosols are not gases. While these elements have a role in climate change, regulatory bodies, such as CARB, or climate change groups, such as the California Climate Action Registry, do not consider these elements as gases that CEQA documents need to report or analyze for control. Therefore, this document does not provide any further discussion of water vapor, atmospheric ozone, or aerosols. 1) Regulatory Background On June 1, 2005, Governor Arnold Schwarzenegger signed Executive Order (EO) S-3-05, which calls for a reduction in GHG emissions to the year 2000 level by 2010, to year 1990 levels by 2020, and to 80 percent below 1990 levels by 2050. The principal overall State plan and policy adopted for the purpose of reducing GHG emissions is Assembly Bill (AB) 32 (California Global Warming Solutions Act of 2006). AB 32 establishes regulatory, reporting, and market mechanisms to achieve quantifiable reductions in GHG City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-41 emissions and establishes a cap on statewide GHG emissions. AB 32 recognizes that California is the source of substantial amounts of GHG emissions. The statute states the following: “Global warming poses a serious threat to the economic well-being, public health, natural resources, and the environment of California. The potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and supply of water to the state from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health- related problems.” In order to avert these consequences, AB 32 establishes a State goal of reducing GHG emissions to 1990 levels by the year 2020, codifying the goal of EO S-3-05. CARB approved a Climate Change Scoping Plan as required by AB 32 in 2008; CARB updates this plan every five years as required by State law. The Climate Change Scoping Plan proposes a “comprehensive set of actions designed to reduce overall carbon GHG emissions in California, improve our environment, reduce our dependence on oil, diversify our energy sources, save energy, create new jobs, and enhance public health”.38 The Climate Change Scoping Plan has a range of GHG-reduction actions, which include direct regulations, alternative compliance mechanisms, monetary and non-monetary incentives, voluntary actions, market based mechanisms such as a cap-and-trade system, and an AB 32 implementation regulation to fund the program. On February 10, 2014, CARB released the Draft Proposed First Update to the Climate Change Scoping Plan.39 The board approved the final First Update to the Climate Change Scoping Plan on May 22, 2014. The first update describes California’s progress towards AB 32 goals, stating that “California is on track to meet the near-term 2020 greenhouse gas limit and is well positioned to maintain and continue reductions beyond 2020 as required by AB 32”.28 The latest update occurred in January 2017 and incorporates the 40 percent reduction to 1990 emissions levels by 2030. The Sustainable Communities and Climate Protection Act of 2008, Senate Bill (SB) 375, established a process to coordinate land use planning, regional transportation plans, and funding priorities in order to help California meet the GHG reduction goals established in AB 32. SB 375 required SCAG to incorporate a SCS into its RTPs that would achieve GHG emission reduction targets though several measures, including land use decisions. SCAG’s SCS is included in the SCAG 2020–2045 RTP/SCS. The goals and policies of the RTP/SCS that reduce VMT focus on transportation and land use planning that include building infill projects; locating residents closer to where they work and play; and designing communities so there is access to high quality transit service. 38 Climate Change Scoping Plan—Pursuant to AB 32.

City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-42 On April 29, 2015, Governor Brown signed EO B-30-15, which ordered an interim statewide GHG emission reduction target to reduce GHG emissions to 40 percent below 1990 levels by 2030 to ensure California meets its target of reducing GHG emissions to 80 percent below 1990 levels by 2050. Five key goals for reducing GHG emissions through 2030 include (1) increasing renewable electricity to 50 percent; (2) doubling the energy efficiency savings achieved in existing buildings and making heating fuels cleaner; (3) reducing petroleum use in cars and trucks by up to 50 percent; (4) reducing emissions of short-lived climate pollutants; and (5) managing farms, rangelands, forests and wetlands to increasingly store carbon. EO B-30-15 also directs CARB to update the Climate Change Scoping Plan to express the 2030 target in terms of million metric tons of carbon dioxide equivalent. On September 8, 2016, the Governor signed Senate Bill 32 (SB 32) to codify the GHG reduction goals of EO B-30-15, requiring the State to reduce GHG emissions by 40 percent below 1990 levels by 2030 (Health and Safety Code Section 38566). As stated above, the State expects this goal to keep the State on track to meeting the goal set by EO S-3-05 of reducing GHG emissions by 80 percent below 1990 levels by 2050. In addition, the Governor of California signed AB 197 to ensure that the State meets the SB 32 goals by requiring CARB to provide annual reports of GHGs, criteria pollutants, and TACs by facility, City and sub-county level, and sector for stationary sources and at the County level for mobile sources. It also requires the CARB to prioritize specified emission reduction rules and regulations and to identify specified information for emission reduction measures (e.g., alternative compliance mechanism, market-based compliance mechanism, and potential monetary and nonmonetary incentive) when updating the Scoping Plan. SB 350, signed October 7, 2015, is the Clean Energy and Pollution Reduction Act of 2015. SB 350 is the implementation of some of the goals of EO B-30-15. The objectives of SB 350 are as follows: 1. To increase from 33 percent to 50 percent, the procurement of our electricity from renewable sources 2. To double the energy efficiency savings in electricity and natural gas final end uses of retail customers through energy efficiency and conservation The text of SB 350 sets a December 31, 2030, target for the State to generate 50 percent of its electricity from renewable sources. SB 350 also requires the State to double statewide energy efficiency savings in electricity and natural gas end uses by 2030. Additionally, SB 350 sets requirements for large utilities to develop and submit integrated resources plans (IRPs), which detail how utilities would meet their customers’ resource needs, reduce GHG emissions, and integrate clean energy resources.40 40 California Energy Commission Clean Energy and Pollution Reduction Act—SB 350.

City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-43 On September 10, 2018, Governor Brown signed SB 100, the 100 Percent Clean Energy Act of 2018. SB 100 requires renewable energy and zero-carbon resources to supply 100 percent of electric retail sales to end-use customers and 100 percent of electricity procured to serve state agencies by December 31, 2045. This policy requires the transition to zero-carbon electric systems that do not cause contributions to increase of GHG emissions elsewhere in the western electricity grid.41 SB 100 also creates new standards for the Renewable Portfolio Standard (RPS) goals established by SB 350 in 2015. Specifically, the bill increases required energy from renewable sources for both investor-owned utilities and publicly owned utilities from 50 percent to 60 percent by 2030. Further, on September 10, 2018, Governor Brown also signed California EO B-55-18, which sets a new statewide goal of carbon neutrality as soon as possible, and no later than 2045 and achieve net negative emissions thereafter. EO B-55-18 was added to the existing Statewide targets of reducing GHG emissions, including the targets previously established by Governor Brown of reducing emissions to 40 percent below 1990 levels by 2030 (EO B-30-15 and SB 32), and by Governor Schwarzenegger of reducing emissions to 80 percent below 1990 levels by 2040 (EO S- 3-05). 2) SCAQMD Significance Criteria On December 5, 2008, the SCAQMD Governing Board presented the staff proposal for a tiered threshold approach wherein Tier 1 determines if a project qualifies for an applicable CEQA exemption, Tier 2 determines consistency with GHG reduction plans, and Tier 3 proposes a numerical screening value as a threshold. At their September 28, 2010, meeting, the Working Group suggested a Tier 3 threshold of 3,000 metric tons of carbon dioxide equivalent (MTCO2e) per year for all land use types.42 Tier 4 determines if the project meets performance standards. Tier 4 has three options: 1) Option 1: percent emission reduction target; 2) Option 2: early implementation of applicable measures; and 3) Option 3: sector-based standard. Tier 5 determines mitigation for CEQA offsets. In the absence of adopted thresholds, this analysis uses the Tier 3 standard.43 The development of project-level thresholds in accordance with CEQA is an ongoing effort at the State, Regional, and County levels, and significance thresholds may differ for future projects based on new or additional data and information that may be available at that time for consideration. The City of Anaheim has not officially adopted any GHG CEQA significance threshold. The City defers to assessment methods and significance thresholds developed by the SCAQMD. This impact analysis evaluates consistency with regulatory programs designed to reduce GHG emissions and that contribute to the achievement of the goals of AB 32 and SB 32 as the primary significance criterion.

Categorical Exemption Analysis Page II-44 this impact analysis also evaluates the Project’s estimated emissions compared to the Tier 3 threshold (as discussed above) for impacts related to GHG emissions proposed by staff of the SCAQMD, but not adopted by the SCAQMD Board. The Tier 3 threshold is an industry standard for the assessment of potential GHG impacts within the South Coast Air Basin and represents the best available guidance in the assessment of potential GHG impacts. 3) GHG Emissions Thresholds Neither the SCAQMD, the City of Anaheim, nor the County of Orange has adopted a significance threshold for GHG emissions from non-industrial development projects. Consequently, pursuant to the discretion afforded by Sections 15064.4(a) and 15064.4(b) of the State CEQA Guidelines, the impact of the Project’s GHG emissions is assessed based on the methodologies proposed by SCAQMD’s GHG CEQA Significance Threshold Working Group, as described above. 4) Impact Analysis The Project would generate GHG emissions from area sources, energy usage, mobile sources, waste, water/wastewater, and construction equipment. The following provides the methodology used to calculate the Project-related GHG emissions and the Project impacts. The analysis used CalEEMod Version 2020.4.0 to calculate the GHG emissions from the Project. The CalEEMod Annual Output for year 2024 for the Project is available in Appendix H of this document. Each source of GHG emissions is described below. (a) Area Sources Area sources include emissions from consumer products, landscape equipment and architectural coatings. The analysis did not make any changes to the default area source emissions. (b) Energy Use Energy usage includes emissions from the generation of electricity and natural gas used on-site. The analysis did not make any changes to the default energy usage parameters. (c) Mobile Sources Mobile sources include emissions from the additional vehicle miles generated from the Project. Per the Final Vehicle Miles Traveled (VMT) Assessment for the Proposed Pepperwood Place Project, 44 this analysis screens since the Project “is located in a low VMT-generating area (<15% below the Orange County Average).” Therefore, this analysis uses the trip generation rates from the TIA to analyze the GHG emissions from the vehicle trips associated with the Project. The basis for the emissions of GHGs associated with mobile sources from operation of the Project are the average daily trip generation rate, trip distance, the GHG emission factors for the mobile 44 Refer to Appendix B, Revised Traffic Impact Assessment for the Pepperwood Place Project, Anaheim, CA, prepared by Linscott Law & Greenspan, June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-45 sources, and the GWP values for the GHGs emitted. The types of vehicles that would visit the Project Site include all vehicle types including automobiles, light-duty trucks, delivery trucks, and waste haul trucks. The modeling for the Project used the vehicle fleet mix for the Orange County portion of the South Coast Air Basin as provided in EMFAC2017 and CalEEMod. According to the TIA, the Project would generate 9.44 daily trips/DU. CalEEMod defaults were used for the Saturday and Sunday trip generation rates. (d) Waste Waste includes the GHG emissions generated from the processing of waste from the Project as well as the GHG emissions from the waste once interred into a landfill. AB 341 requires the diversion of 75 percent of waste from landfills by 2020. To be conservative, the analysis did not make any reductions for compliance with AB 341. The analysis did not make any other changes were made to the default waste parameters. (e) Waste/Wastewater Water includes the water used for the interior of the building as well as for landscaping and is based on the GHG emissions associated with the energy associated with supplying and treating water and wastewater. California Green Building Standards require a 20 percent reduction in indoor water usage. To be conservative, the analysis did not take any reductions or make any changes to the default water usage parameters. (f) Construction The construction-related GHG emissions were also included in the analysis and based on a 30- year amortization rate as recommended in the SCAQMD GHG Working Group meeting on November 19, 2009. CalEEMod calculated the construction-related GHG emissions using the parameters described above. A summary of the results is below in Table II-11, Project-Related GHG Emissions, and the CalEEMod Model runs for the Project are provided in Appendix H of this document. Table II-11, Project-Related GHG Emissions, shows that the Project’s GHG emissions would be 177.67 MTCO2e per year.

Categorical Exemption Analysis Page II-46 Table II-11 Project-Related GHG Emissions Emissions Source Estimated Project Generated CO2e Emissions (Metric Tons per Year) Calculation sheets are provided in Appendix H of this document. Source: CalEEMod Version 2020.4.0 for Opening Year 2024. As it is noted, there are no established applicable quantitative federal, State, regional, or local CEQA significance criteria for GHG emissions for non-industrial projects in the SoCAB. The SCAQMD has proposed, but not adopted, a threshold of 3,000 MTCO2e per year for non-industrial land use projects. As shown, the estimated GHG emissions from the Project would be less than this suggested threshold. The impact would be less than significant. (g) Consistency with Scoping Plan (AB 32) The City does not have an adopted Climate Action Plan (CAP) or Citywide GHG Reduction Plan applicable to land use development projects. As such, this consistency analysis focuses on the 2017 Scoping Plan, SCAG’s Connect SoCal RTP/SCS, SB 32, and Title 24. The Project would be subject to compliance with all building codes in effect at the time of construction, which would include energy conservation measures mandated by Title 24 of the California Building Standards Code – Energy Efficiency Standards. Because Title 24 standards require energy conservation features in new construction (e.g., high- efficiency lighting, high-efficiency heating, ventilating, and air conditioning (HVAC) systems, thermal insulation, double-glazed windows, water conserving plumbing fixtures), they indirectly regulate and reduce GHG emissions. California's Building Energy Efficiency Standards are updated on an approximately three-year cycle. The most recent 2019 standards went into effect January 1, 2020. Further, the Project would be subject to compliance with the South Coast AQMD’s proposed GHG threshold and would not interfere with the State’s goals of reducing GHG emission. The Project would comply with the City’s General Plan policies and State Building Code provisions designed to reduce GHG emissions. Approximately 90 percent of the Project’s emissions would be from energy and mobile sources, which would be further reduced by 2017 Scoping Plan implementation. In addition, the City has no control over vehicle emissions (approximately 64 percent of the project’s total emissions). However, these emissions would decline in the future due to statewide measures including the reduction in the carbon content of fuels, CARB’s advanced clean car program, CARB’s mobile source strategy, fuel efficiency standards, cleaner technology, and fleet turnover. Additionally, SCAG expects implementation of its RTP/SCS to help California reach its GHG reduction goals, with reductions in per capita transportation emissions of 19 percent 2035.45 The Project is an infill development project near large employment centers, local-serving commercial uses, and several OCTA transit stops along Ball Road, thereby potentially reducing 45 Southern California Association of Governments, Connect SoCal 2020–2045 RTP/SCS, September 3, 2020, p. 9 City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-47 the need to travel long distances.46 Accordingly, the Project would not interfere with the State’s efforts to reduce GHG emissions in 2030. The 2017 Scoping Plan builds on the 2008 Scoping Plan in order to achieve the 40 percent reduction from 1990 levels by 2030. Major elements of the 2017 Scoping Plan framework that would achieve the GHG reductions include: • Implementing and/or increasing the standards of the Mobile Source Strategy, which include increasing Zero Emission Vehicle (ZEV) buses and trucks. When adopted, this measure would apply to all trucks accessing the Project Site; this may include existing trucks or new trucks purchased by the project proponent, which could be eligible for incentives that expedite the Project’s implementation of ZEVs. • Low Carbon Fuel Standard (LCFS), with an increased stringency (18 percent by 2030). When adopted, this measure would apply to all fuel purchased and used by the Project in the state. • Implementing SB 350, which expands RPS to 50 percent and doubles energy efficiency savings by 2030. When adopted, this measure would apply when electricity is provided to the Project by a utility company. • California Sustainable Freight Action Plan, which improves freight system efficiency, utilizes near-zero emissions technology, and deployment of ZEV trucks. When adopted, this measure would apply to all trucks accessing the Project site, this may include existing trucks or new trucks that are part of the statewide goods movement sector. • Implementing the proposed Short-Lived Climate Pollutant Strategy (SLPS), which focuses on reducing methane and hydrofluorocarbon emissions by 40 percent and anthropogenic black carbon emissions by 50 percent by year 2030. When adopted, the Project would be required to comply with this measure and reduce SLPS accordingly. • Continued implementation of SB 375. The Project is not within the purview of SB 375 and would therefore not conflict with this measure. • Post-2020 Cap-and-Trade Program that includes declining caps. When adopted, the Project would be required to comply with the Cap-and-Trade Program if it generates emissions from sectors covered by Cap-and-Trade. • 20 percent reduction in GHG emissions from refineries by 2030. When adopted, the Project would be required to comply with this measure if it were to utilize any fuel from refineries. 46 The California Air Pollution Control Officers Association, Quantifying Greenhouse Gas Mitigation Measures (August 2010) identifies that infill developments, such as the proposed project reduce vehicle miles traveled which reduces fuel consumption. Infill projects such as the proposed project would have an improved location efficiency. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-48 • Development of a Natural and Working Lands Action Plan to secure California’s land base as a net carbon sink. This is a statewide measure that would not apply to the Project. As shown above, the Project would not conflict with any of the 2017 Scoping Plan elements as any regulations adopted would apply directly or indirectly to the Project. Furthermore, recent studies show that the State’s existing and proposed regulatory framework would allow the State to reduce its GHG emissions level to 40 percent below 1990 levels by 2030.47 Concerning Executive Order S-3-05 goals for 2050, it is not currently possible to quantify all emissions savings from future regulatory measures because government agencies have not yet developed the measures. Just as the project’s GHG emissions would decrease over time from the known regulations that the State would phase in over time, it can be anticipated that project operations would benefit from all applicable measures enacted by State lawmakers to reach the goal of an 80 percent reduction below 1990 levels by 2050. This percentage reduction in the level of GHG emissions that the State’s GHG regulators believe the State needs to achieve in order to stabilize GHG-induced temperature increases and limit GHG impacts in California’s environment. The basis for the analysis included in this Categorical Exemption is generally the Consultant’s knowledge about current GHG emissions regulations and its prediction of GHG impacts, to the extent possible, based on scientific and factual data. Further analysis would be speculative; therefore, in compliance with CEQA, this Categorical Exemption provides no further analysis or conclusions concerning the project’s long-term GHG impacts. In addition, the project would be subject to compliance with applicable building codes and South Coast AQMD rules and regulations during the construction and operational phases, therefore, would not interfere with the State’s goals of reducing GHG emissions. Therefore, the Project would not conflict with an applicable plan, policy, or regulation (e.g., Title 24, AB 32, and SB 32) adopted to reduce GHG emissions. Impacts would be less than significant. 5) Summary As explained in detail in above subsections, the Project would not result in any significant effects relating to greenhouse gases. e) Project-Specific Water Quality Impacts 1) Groundwater The Project does not involve the extraction of groundwater and it would not result in a reduction in aquifer volume or lower the local groundwater table. Groundwater was recorded at depths ranging from approximately 10.5 to 14.0 feet below the existing ground. Similar groundwater depths ranging from 13 to 15 feet below ground surface were measured during the drilling of hollow stem auger borings on-site. The Department of Conservation’s seismic hazard zone report 47 California Legislative Information, Senate Bill No. 32. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-49 puts historic high groundwater for the site at a depth of less than 10 feet.48 Fluctuations in the level of groundwater may occur due to variations in rainfall, temperature, and other factors. However, due to the depth of the groundwater anticipated on the Project Site, the operation of the Project would not interfere with any groundwater recharge activities within the area. The Project Site’s existing condition is a vacant lot that was previously developed with a single-family home and accessory garage and the degree to which any surface water infiltration and groundwater recharge occurs on-site is negligible. Moreover, the Project would redevelop the entire site. Therefore, impacts to groundwater would be less than significant. Therefore, as the Project Site would not result in any significant effects related to groundwater water quality, the Project meets this condition for water quality. 2) Surface Water The following surface water impact analysis summarizes and incorporates by reference the information provided in the Water Quality Management Plan for the TR 17944, 910 S. Western Ave., Anaheim, CA 92804, prepared by Mayers & Associates Civil Engineering, Inc., August 2021 (WQMP). The WQMP is available as Appendix I to this document. A project would normally have a significant impact on surface water quality if discharges associated with a project would create pollution, contamination, or nuisance as defined in Section 13050 of the California Water Code (CWC) or that cause regulatory standards to be violated, as defined in the applicable National Pollution Discharge Elimination System (NPDES) stormwater permit or Water Quality Control Plan for the receiving water body. For the purpose of this issue, a significant impact may occur if a project would discharge water which does not meet the quality standards of agencies which regulate surface water quality and water discharge into stormwater drainage systems. Significant impacts would also occur if a project does not comply with all applicable regulations with regard to surface water quality as governed by the State Water Resources Control Board (SWRCB). These regulations include compliance with the Standard Urban Storm Water Mitigation Plan (SUSMP) requirements to reduce potential water quality impacts. (a) Construction During construction, the Project Site would contain a variety of construction materials such as adhesives, cleaning agents, landscaping, plumbing, painting, heat/cooling, masonry materials, floor and wall coverings, and demolition debris. Spills of construction materials can be a source of stormwater pollution and/or soil contamination. All hazardous materials are to be stored, labeled and used in accordance with the U.S. Occupational Safety and Health Administration regulations. These regulations for routine handling and storing of hazardous materials effectively control the potential stormwater pollution caused by these materials. 48 Refer to Appendix K, Updated Geotechnical Investigation for Proposed Twelve Single-Family Homes Tentative Tract 17944, 910 South Western Avenue, City of Anaheim, California, prepared by PETRA GeoSciences, June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-50 Earth moving activities would involve preparation of the Project Site for Project construction. Soil erosion is the process by which soil particles are removed from the land surface, by wind, water and/or gravity. Soil particles removed by stormwater runoff can have negative impacts on downstream conditions through increased sedimentation as well as spread of contaminants found in the exposed soil of the Project Site. Grading activities can greatly increase erosion processes. Two general strategies are typically required to prevent construction silt from entering drainage courses. First, the amount of exposed soil is typically limited and erosion control procedures are implemented for those areas that must be exposed. Common methods for controlling fugitive dust emissions, such as covering truck loads and street sweeping, are also effective in controlling stormwater quality. Second, the construction area would be secured to control off-site migration of pollutants. Erosion control devices, including temporary diversion dikes/berms, drainage swales, and siltation basins, are typically required around construction areas to ensure that sediment is trapped and properly removed. The Project’s proposed construction activities would be required to comply with the State’s General Construction National Pollutant Discharge Elimination System (NPDES) Permit and the development of a construction Storm Water Pollution Prevention Plan (SWPPP) because the Project Site is greater than one acre in size. The Project SWPPP would identify potential pollutant sources that may affect the quality of discharge associated with construction activity, identify non- storm water discharges, and provide design features to effectively prohibit the entry of pollutants into the public storm drain system during construction. The Applicant has prepared a Water Quality Management Plan (WQMP) for the Project Site to comply with the requirements of the County of Orange NPDES Stormwater Program. The WQMP specifies best management practices (BMPs) that the Applicant would use during construction, which include but are not be limited to, erosion control, sediment control, non-stormwater management, and materials management. When properly designed and implemented, BMPs would ensure that construction of the Project would not result in degradation of surface water quality through increased sedimentation or spread of soil contaminants. Accordingly, required compliance with the City of Anaheim grading permit regulations and implementation of BMPs would ensure that Project construction would not create a significant impact by degrading surface water quality, or by causing a violation of applicable water quality standards. Therefore, as the Project Site would not result in any significant effects related to construction surface water quality, the Project meets this condition for water quality. (b) Operation Operation of the Project would introduce sources of potential water pollution that are typical of residential developments. Anticipated and potential pollutants generated by the Project are sediment, nutrients, pesticides for landscaping, metals, pathogens, oil and grease and cleaning solvents. The Project’s proposed residential land uses do not represent the type of use that would otherwise degrade water quality (e.g., an industrial land use that could adversely affect water quality). Furthermore, operation of the Project would not result in discharges that would cause regulatory standards to be violated. The Project Site currently has approximately 14 percent impervious surfaces. Project development would increase the impervious surfaces to 67 percent. Project site BMPs have been designed to prevent storm water pollution that includes two drainage City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-51 management areas (DMAs). The stomwater treatment facility that is proposed for each DMA is infiltration, via permeable pavement. The design capture volume (DCV) would be treated by passing through the stone layer of the permeable pavers and allowing the runoff to infiltrate while reducing the peak runoff velocity and volume. The permeable pavers contain stone for physically and chemically capturing pollutants from DCV. The DCV would be treated through the porosity of the stones in the reservoir portion of the pavers and ultimately infiltrate into the ground. The treated stormwater would infiltrate into the ground and only in heavy stormwater conditions, would the stormwater overflow from the sump condition onto Western Avenue. Specifically, DMA A is .70 acres, which is located in the north side of the Project Site and would drain to the northern portion of the permeable pavers. These permeable pavers would treat the run-off from roofs, pads and a portion of the street and ultimately infiltrate to the ground. DMA B is .69 acres, which is located in the south side of the Project Site and would drain to the southern portion of the permeable pavers. These permeable pavers would treat the run-off from roofs, pads and a portion of the street and ultimately infiltrate to the ground. In conclusion, during a low flow event, stormwater would travel to the permeable pavers where water would infiltrate into the ground. During a high flow event water would travel to permeable pavers like during the low flow event. The reservoir portion of the permeable pavers have enough volume to hold the net 100-year flow from the existing site to the proposed site. The permeable paver would hold 3,300 cubic feet of volume within the 4 inch depth of bedding course and subbase. Once the permeable pavers are to capacity in the sump condition, water would overflow the grading ridgeline and spill over onto Western Avenue matching existing site conditions. Per the WQMP for infiltration BMP feasibility, it has been concluded that infiltration is feasible due to having an infiltration rate of 0.98 inches/hr which is higher than the minimum threshold of 0.6 inches/hr. Overall, the Project would comply with all applicable State, regional, and local regulations, policies, and requirements with regard to surface water quality and implement BMPs for the control and retention of stormwater and eroded sediments. Based on the above, the Project would result in less than significant impacts to surface water quality during operation. Therefore, as the Project Site would not result in any significant effects related to operation surface water quality; therefore, the Project meets this condition for water quality. 3) Summary As the approval of the Project would not result in any significant effects relating to traffic, noise, air quality, greenhouse gases, or water quality, the Project meets this condition. Condition (e): The site can be adequately served by all required utilities and public services. The following provides a Project-specific analysis of the impacts to utilities and public services that would serve the Project. f) Utilities 1) Water Treatment Facilities and Existing Infrastructure City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-52 Anaheim Public Utilities Department (APUD) currently supplies water to the Project Site. APUD is responsible for ensuring that the City meets its water demand and that it can achieve State and federal water quality standards. The APUD ensures the reliability and quality of its water supply through an extensive distribution system that includes more than 752 miles of pipes, 4 active wells, and 13 treated water reservoirs.49 The APUD divides the City’s water distribution system into two main geographic areas; the “Flatland Area” and the “Hill and Canyon Area.” The Project Site is located within the “Flatland Area.” The “Flatland Area” is approximately 22,500 acres, situated generally north and west of the Santa Ana River, and served primarily by groundwater (with Metropolitan Water District (MWD) imported water supplemented, as necessary). 50 Implementation of the Project would not measurably reduce groundwater levels, and as such, no new or expanded water treatment facilities would be required. Further, the Project would be within the growth projections of the APUD and it is, therefore, APUD anticipates that it would be able to meet the Project’s water treatment demand.51 Therefore, APUD can adequately serve the site with respect to Lenain Water Treatment Plant (LWTP). In addition to supplying water for domestic uses, APUD also supplies water for fire protection services, in accordance with the Fire Code. The Anaheim Fire and Rescue Department (AFR) requires a water flow of 1,500 gallons per minute (gpm). If water main or infrastructure upgrades are required to serve the Project, the Code requires the Project Applicant to pay for such upgrades, which the Project Applicant or APUD would construct. To the extent such upgrades result in a temporary disruption in service, proper notification to APUD customers would take place, as is standard practice. In the event that water main and other infrastructure upgrades are required, it would not be expected to create a significant impact to the physical environment because: (1) any disruption of service would be of a short-term nature; (2) replacement of the water mains would be within public rights-of-way; and (3) any foreseeable infrastructure improvements would be limited to the immediate Project vicinity. Therefore, APUD can adequately serve the Project Site with respect to fire flow requirements. Furthermore, the Project would comply with the City’s mandatory water conservation measures that, relative to the City’s increase in population, have reduced the rate of water demand in recent years. APUD bases its growth projections on conservation measures and adequate treatment capacity that is, or would be, available to treat APUD’s projected water supply, as well as the APUD’s expected water sources. Compliance with water conservation measures, including Title 20 and 24 of the California Administrative Code would serve to reduce the projected water demand. Chapter 10.18 of Code comprises the City’s Water Conservation and Water Contingency Rules and Regulations. The Water Conservation Water Contingency Rules and Regulations stipulate conservation measures pertaining to water closets, showers, landscaping, maintenance activities, and other uses. At the State level, Title 24 of the California Administrative Code contains the California Building Standards, including the California Plumbing Code (Part 5), which promotes water conservation. Title 20 of the California Administrative Code addresses 49 2015 UWMP, June 2016. 50 City of Anaheim-Public Utilities-Water Services-About Water Services website: http://www.anaheim.net/1694/About-Water-Services, accessed: June 2021. 51 2015 UWMP, June 2016. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-53 Public Utilities and Energy and includes appliance efficiency standards that promote conservation. Various sections of the Health and Safety Code also regulate water use. On April 7, 2017, following unprecedented water conservation averaging approximately 25 percent across the State and plentiful winter rain and snow, the governor ended the drought state of emergency in most of California (including Orange County) through Executive Order B40-17. Executive Order B-40-17 builds on actions taken in Executive Order B-37-16, which remains in effect, to continue making water conservation a way of life in California.52 Executive Order B-37- 16 (Making Water Conservation a California Way of Life) directs the California Department of Water Resources to work with the State Water Resources Control Board (SWRCB) to make some of the requirements of the emergency conservation regulation permanent so as to build upon and exceed the existing State law requirements to achieve a 20 percent reduction in urban water usage by 2020. The basis for these water use targets are strengthened standards that were developed in response to the State’s conservation mandate regarding indoor residential per capita water use; outdoor irrigation, in a manner that incorporates landscape area, local climate, and new satellite imagery data; commercial, industrial, and institutional water use; and water lost through leaks. Overall, the Project’s water demand would comprise a small percentage of APUD’s existing water supplies. Moreover, as discussed below, the Project’s anticipated water demand is consistent with demand projected under the Anaheim 2015 Urban Water Management Plan (UWMP). Therefore, APUD can adequately serve the site with respect to water conservation. 2) Wastewater Treatment Facilities and Existing Infrastructure The City’s Sewer and Storm Drain Maintenance Division provides sewer service to the Project area. The Project Site has existing sewer connections to the City’s sewer system via a sewer lateral that conveys wastewater into an 8-inch vitrified clay pipe (VCP) located along Western Avenue. Sewage from the Project Site is proposed to be discharged into a new 8-inch private VCP sewer connection located along the proposed private street running through the center of the Project Site.53 The 8-inch private VCP sewer connection would connect to an existing 10-inch sewer main along the centerline of Western Avenue that is currently identified as hydraulically deficient. The 10-inch main upsizes to a 12-inch sewer main at Ball Road. The sewer main continues south to the southern city limits and outfalls to the City of Stanton sewer collection system.54 To determine the effects of altering land uses within the Project area as proposed by the Project, two model scenarios were analyzed, which focus on the pipes downstream of the Project’s proposed sewer connection point. The two scenarios are West Anaheim Master Plan of Sanitary Sewer (WAMPSS) Existing Condition plus the Development and the WAMPSS Build-Out Condition plus the Development. 52 State Water Resources Control Board, Press Room, Announcements, State Releases Plan to Make Water Conservation a Way of Life, April 7, 2017. 53 Refer to Appendix J, Tentative Tract Map No. 17944. 54 Refer to Appendix E, 910 S. Western Avenue Development Sewer Analysis, prepared by GHD, January 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-54 WAMPSS Existing Condition plus the Development The flow for the existing single-family home was removed from the scenario and replaced with the flows for the Project. The steady state loading from the Project in this scenario is 3,600 gpd. Analysis of this scenario revealed no deficiencies in the pipelines downstream of the Project.55 WAMPSS Build-Out Condition plus the Development The WAMPSS Build-Out model scenario includes loadings from the Project. The steady state loading from the Project in this scenario remains at 3,600 gpd, which represents a decrease of 1,500 gpd over the WAMPSS Build-Out loading since the number of dwelling units proposed for this Project is lower than the number of units estimated for the WAMPSS Build-Out model scenario. Analysis of this scenario also revealed no deficiencies in the pipelines downstream of the proposed development.56 The Orange County Sanitation District (OCSD) treats the wastewater collected within City. Sewage from the Project Site is ultimately conveyed via existing sewer infrastructure to either Reclamation Plant No. 1, located in the City of Fountain Valley, which has the capacity to treat approximately 182 million gallons per day (mgd) of wastewater to full secondary treatment level and currently treats 121 mgd; or, Reclamation Plant No. 2, located in the City of Huntington Beach, which has the capacity to treat approximately 150 mgd of wastewater to full secondary treatment level and currently treats 90 mgd. The remaining capacity at Reclamation Plant No. 1 is approximately 61 million gpd or approximately 34 percent of its total capacity, and the remaining capacity at Reclamation Plant No. 2 is approximately 60 million gpd or approximately 40 percent of its total capacity.57 Although these treatment capacities would expand in the future, these existing design capacities would be sufficient to serve the Project. Therefore, OCSD can adequately serve the site with respect to wastewater treatment. Given the infill location of the Project Site, surrounded by residential uses served by existing utility infrastructure, it is reasonable to anticipate that the existing sewer line located in Western Avenue has sufficient capacity to accommodate the additional flow. Nonetheless, prior to issuance of building permits, the City would require detailed gauging and evaluation of the Project’s wastewater connection point at the time of connection to the system. If the City identifies deficiencies at that time, the Project Applicant would be required, at its own cost, to build secondary sewer lines to a connection point in the sewer system with sufficient capacity, in accordance with standard City procedures. The installation of any such secondary lines, if needed, would require minimal trenching and pipeline installation in accordance with all City permitting requirements, which would be a temporary action and would not result in any adverse environmental impacts. Therefore, the site can be adequately served by OCSD with respect to sewer line infrastructure. 3) Existing and Projected Water Supply 55 Refer to Appendix E, 910 S. Western Avenue Development Sewer Analysis, prepared by GHD, January 2021. 56 Ibid. 57 Orange County Sanitation District, Budget Update, Fiscal Year 2019-2020. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-55 The City’s water supply primarily comes from a mixture of groundwater and imported. Historically, approximately 70 percent groundwater pumped came from local wells and approximately 30 percent from the MWD, obtained from the Colorado River Aqueduct.58 However, the 70/30 split no longer applies since most of the City’s wells have been taken offline as of March 2020. As of April 2021, there are only 4 active wells, while the remainder of wells have been taken offline due to either PFAS (a group of chemicals referred to as per- and polyfluoroalkyl substances) or mechanical issues. Currently, the majority of the City’s water supply comes from imported water. Over the next several years, the City would be working on constructing groundwater treatment facilities to treat PFAS. Nevertheless, the City’s UWMP anticipates the same water supply mix to be available to the City through 2040. Further, MWD uses a land use-based planning tool that allocates projected demographic data from SCAG into water service areas for each of MWD’s member agencies. These sources, along with recycled water, would supply the City’s water needs in the years to come. The 2015 UWMP water demand projection for 2040 is approximately 67,143 acre-feet for a normal year and 71,172 acre-feet for a single-dry and multiple-dry years. The 2015 UWMP states that the available demand would be due to diversified supply and conservation measures.59 The City is also making efforts to increase the availability of water supplies, including increasing recycled water use and identification of alternative water supplies, such as water transfer and stormwater runoff reuse, as well as implementing management agreements for long-term groundwater use strategies to prevent overdraft. Consideration of existing sources of supply, coupled with the combined effect of these City efforts to increase available water supplies, would assure adequate water supplies for the Orange County Water District (OCWD) service area through at least 2040. Therefore, the amount of new annual demand from the Project would be insignificant relative to available supplies through 2040, projected growth in Anaheim, and planned water resource development by OCWD. OCWD’s Water System Budget Report for the Fiscal Years 2020-2021 details OCWD’s process of capital upgrades to the water infrastructure system of the City and increasing its water resources, enhance the quality of water it distributes, and improve the security of the water supply. These goals are accomplished by replacing and/or adding to the water system infrastructure, complying with and/or exceeding all state and federal water regulations, looking for new sources of water supply as well as conserving those already in existence, and adopting new and improved security measures to ensure the safety of the City’s water. Through this program, OCWD can provide reliable sources of water to the residents of the City.60 Thus, sufficient water supplies would be available to serve the Project from existing entitlements and resources, and new or expanded entitlements would not be necessary. Moreover, the Project’s housing and population increases are consistent with the RTP/SCS and UWMP (making the addition of 12 single-family residential units resulting from the Project consistent with regional growth). Thus, the Project’s estimated water usage is within applicable projections and does not exceed the amount anticipated by the City’s long-range land use and planning efforts. 58 2015 UWMP, June 2016. 59 Ibid. 60 Orange County Waster District, Budget Report for Fiscal Years 2020-2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-56 Thus, the Project would not create any water system capacity issues, and sufficient reliable water supplies would be available to meet Project demands. Therefore, the site can be adequately served by OCWD with respect to water supply. 4) Solid Waste Disposal Solid waste generated within the City is disposed of at privately-owned landfill facilities throughout Orange County. The Sanitation Services Division, in coordination with Republic Services, a private waste, recycling and disposal company, provides waste collection services for developments within the City. As is typical for most solid waste haulers in the Anaheim area, Republic Services separates and recycles all reusable material collected from the Project Site at a local materials recovery facility. The remaining solid waste would be disposed of at a variety of landfills. Most commonly, the Olinda Alpha Landfill serves the City. This Class III landfill accepts non-hazardous solid waste including construction and demolition waste.61 Additionally, the Frank R. Bowerman Landfill near the City of Irvine and the Prima Deshecha Landfill near the City of San Juan Capistrano receives refuse, generated from the City. (a) Construction Implementation of the Project would generate construction and demolition waste. Construction and demolition debris includes concrete, asphalt, wood, drywall, metals, concrete rubble, and other miscellaneous and composite materials. The construction of the Project would generate approximately 77 tons of solid waste.62 As required by the City of Anaheim Construction and Demolition Waste Diversion Application, permitted haulers would haul Project construction waste to City-certified construction and demolition processing facilities, monitored for compliance with recycling regulations. The inert solid waste and soil would require disposal at the County’s operating inert landfills (Olinda Alpha, Frank R. Bowerman, and Prima Deshecha) or at any of a number of state-permitted Inert Debris Engineered Fill Operations in the County. This does not include any asbestos-containing materials (ACMs), lead-based paints (LBPs), polychlorinated biphenyl (PCB), contaminated soil, or other contaminated waste, which would be disposed of at facilities licensed to accept such waste. In compliance with the requirements of SB 1374, the Applicant would implement a construction waste management plan to recycle and/or salvage a minimum of 65 percent of non-hazardous demolition and construction debris. This forecasted solid waste generation is a conservative estimate as it assumes no reductions in solid waste generation would occur due to recycling. Moreover, there is current capacity available in the County for the disposal of waste. Olinda Alpha Landfill has an 18 percent remaining capacity, Frank R. Bowman Landfill has a 67 percent remaining capacity, and Prima Deshecha Landfill has a 99 percent remaining capacity.63 Therefore, the Project-generated construction waste of 77 tons (i.e., asphalt and construction debris) would represent a small percentage of the inert waste disposal 61 County of Orange Waste & Recycling-Landfills website: https://oclandfills.com/landfills/active-landfills/olinda- landfill, accessed: June 2021. 62 A construction waste generation rate of 4.38 pounds per square foot was used. 35,040 square feet of construction multiplied by 4.38 pounds is 153,475 pounds (76.7 tons).

City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-57 capacity in the region. Thus, the Project would not generate construction-generated inert waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise affect the attainment of solid waste reduction goals. Therefore, the site can be adequately served by landfills with respect to construction solid waste disposal. (b) Operation AB 374 mandates a 75 percent landfill diversion rate by 2020.64 The City’s Public Works Department develops and implements source reduction, recycling, and re-use programs in the City. The Sanitation Services Section provides technical assistance to public and private recyclers, manages the collection and disposal programs for Household Hazardous Waste, and helps create markets for recycled materials. With the State-mandated minimum diversion rate of 75 percent, there would be adequate landfill capacity for the Project’s operational impact. Therefore, the site can be adequately served by landfills with respect to operational solid waste disposal. 5) Natural Gas Existing Infrastructure Southern California Gas Company (SCG) provides natural gas service to the City, including the Project Site. The 2020 California Gas Report presents a comprehensive outlook for natural gas requirements and supplies for California through 2035. SCG expects its active meter growth to increase by an annual average of 0.58 percent from the period 2019 through 2035; however, SCG expects natural gas demand in its service area would decline at an annual rate of 1.0 percent during this same period. Specifically, the SCG expects residential load in Southern California to decline by 1.7 percent annually from 238 billion cubic feet in 2019 to 198 billion cubic feet in 2035. The decrease in gas demand results from a combination of continued decline in residential use per meter, increases in marginal gas rates, the impact of savings from SCG’s Advanced Metering Infrastructure (AMI) project deployment, which began in 2013, and CPUC authorized energy efficiency program savings in this market. SCG forecasts that these energy efficiency savings would lead to very large reductions in residential gas use equaling a total of 18.8 billion cubic feet in year 2035.65 The Project’s natural gas consumption would represent an extremely small percentage of SCG’s total usage supplied to residential buildings. Also, as the Project would be infill redevelopment, there is already a natural gas connection point; expansion for distribution infrastructure would not be required and capacity-enhancing alterations to existing facilities would be highly unlikely. SCG is satisfactorily meeting its obligations to its current customers and projects to meet obligations of its future customers. As such, SCG’s existing infrastructure and storage supplies are well-prepared for the long-term forecasts. However, in the event SCG cannot provide service from the existing infrastructure, a system analysis would be conducted by SCG to determine the best method to provide service and appropriate actions such as pressure betterments may be initiated to resolve the issue. Thus, any corrective action, albeit unlikely, would be minimal and temporary, and would 64 California Department of Resources and Recycling, California’s 75 Percent Initiative. 65 California Gas and Electric Utilities, 2020 California Gas Report, page 99. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-58 not result in any adverse environmental impacts. Therefore, SCG can adequately serve the Project Site with respect to natural gas. 6) Electrical Power Existing Infrastructure APUD provides electrical service to the City, including the Project Site. On February 28, 2017, APUD adopted the 2018 Integrated Resource Plan (IRP), which provides a 20-year roadmap to guide APUD in meeting future energy needs by forecasting demand for energy and determine how APUD would meet that demand by executing new projects and replacement projects and programs.66 The IRP lays out alternative strategies for meeting APUD’s regulatory requirements and environmental policy goals for increasing renewable energy and reducing GHG emissions, while maintaining power reliability. The IRP provides detailed analysis and results of resource cases, which investigate the economic and environmental impact of increased Renewable Portfolio Standard (RPS), local solar, energy storage, and various levels of transportation electrification within a 20-year horizon. APUD generates power from a variety of different sources that include renewable energy, hydroelectric, natural gas, and other fuels. APUD utilizes renewable energy sources and is committed to meeting the requirement of the RPS Enforcement Program to use at least 33 percent of the State’s energy from renewables by 2020.67 Current installed generation capacity is over 5,086 megawatts of power per day.68 The APUD serves the Project Site for electrical power. APUD routinely plans capacity additions and changes at existing and new facilities as needed to supply area load. The Project’s electrical consumption would be part of the total load growth forecast for the City and accounted for in the planned growth of the City’s power system. Furthermore, as the Project would be infill redevelopment, there is already an electrical power connection point, and expansion for distribution infrastructure would not be required, nor would capacity-enhancing alterations to existing facilities be required from Project implementation. Therefore, APUD can adequately serve the Project Site with respect to electrical power. g) Public Services 1) Fire Protection Anaheim Fire & Rescue (AFR) provides fire protection services in the City and operates 11 fire stations, comprised of 11 engine companies, and employs approximately 270 firefighters along with various other support staff.69 66 Anaheim Public Utilities, 2018 Integrated Resource Plan, February 2017. 67 California Environmental Protection Agency, Air Resources Board, Renewable Portfolio Standard. 68 Anaheim Public Utilities-About Electric Services, website: https://www.anaheim.net/2104/About-Electric- Services, accessed: June 2021. 69 City of Anaheim Fire and Rescue Department-Administration, website: https://www.anaheim.net/665/Administration, accessed: June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-59 The Project is closest to Fire Station No. 11, located at 3078 W. Orange Avenue, approximately 0.7-roadway-miles to the northeast from the Project Site.70 Fire Station No. 11 includes an engine company, an ambulance, and an OES. Furthermore, Fire Station No. 4, located at 2736 W. Orange Avenue, approximately 1.6-roadway-mile to the northeast from the Project Site, would also aid as needed. Fire Station No. 4 includes an engine company. The AFR bases the adequacy of its fire protection upon the required fire flow, equipment access, and AFR’s safety requirements regarding needs and service for the area. The required fire flow necessary for fire protection varies with the type of development, life hazard, occupancy, and the degree of fire hazard. Pursuant to Code Title 16, City-established fire flow requirements vary from 1,500 gpm in low-density residential areas to 8,000 gpm in high-density commercial or industrial areas. In any instance, a minimum residual water pressure of 20 pounds per square inch (PSI) is to remain in the water system while the required gpm is flowing. Code Title 16 identifies a fire flow requirement of 1,500 gpm for one-family residential projects such as the Project. AFR would confirm the adequacy of existing water pressure and availability in the Project area with respect to required fire flow prior to issuance of building permits. As part of the normal building permit process, the Project would be required to upgrade water service laterals, meters, and related devices, as applicable, in order to provide required fire flow; however, the AFD does not anticipate the need for new water facilities to serve the Project. Moreover, if needed, the Project would implement such improvements either on-site or off-site within the right-of-way, and as such, the construction activities would be temporary and not result in disruption of service to neighboring properties. Code Title 16 (Fire) addresses land use-based requirements for fire hydrant spacing and type, which states that no structure shall be more than 300 feet travel distance from a fire hydrant. The nearest fire hydrant is located just south of the Project Site, on the east side of Western Avenue. The Project would implement City Building and Fire Code requirements regarding Project components including, but not limited to, structural design, building materials, site access, clearance, hydrants, and fire flow. The Applicant would demonstrate compliance with these requirements prior to issuance of a building permit in accordance with City regulations as part of AFR’s plan review. AFR would confirm implementation through its safety inspection for new construction projects. Construction activities to install any new pipes or pumping infrastructure would be temporary and of short duration and would not result in any disruption of service to neighboring properties. AFR would continue to provide emergency vehicle access to the Project Site from local roadways. All improvements proposed would comply with the Fire Code, including any additional access requirements of AFR. Additionally, the Applicant would maintain emergency access to the Project Site at all times during both Project construction and operation pursuant to the Worksite Traffic Control Plan that would be prepared for the Project and approved by the City. 70 City of Anaheim Fire and Rescue Department-Facilities, website: https://www.anaheim.net/Facilities?clear=False, accessed: June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-60 Therefore, the AFR can adequately serve the Project Site by fire facilities including adequate proximity to a fire station, fire flow, fire hydrants, and emergency access. 2) Police Protection The City of Anaheim Police Department’s (APD) East Station would serve the Project Site. The West Station is located at 320 South Beach Boulevard, approximately 1.2-roadway-mile to the northeast of the Project Site.71 (a) Construction Construction sites, if not properly managed, have the potential to attract criminal activity (such as trespassing, theft, and vandalism) and can become a distraction for local law enforcement from more pressing matters that require their attention. However, as required by the City as a regulatory compliance measure, the Project would employ construction safety features including erecting temporary fencing along the periphery of the active construction areas to screen as much of the construction activity from view at the local street level and to deter trespassing, vandalism, short- cut attractions, potential criminal activity, and other nuisances. Therefore, the APD can adequately serve the site with respect to police protection and services during construction. (b) Operation Responses to thefts, vehicle burglaries, vehicle damage, traffic-related incidents, and crimes against persons may increase because of the Project due to increased on-site activity and increased traffic on adjacent streets and arterials. The Project would include adequate and strategically positioned lighting to enhance public safety. Visually obstructed and infrequently accessed “dead zones” would be limited, and, where possible, security controlled to limit public access. Additionally, the continuous visible and non-visible presence of residents at all times of the day would provide a sense of security during evening and early morning hours. As such, the Project’s residents would be able to monitor suspicious activity in the neighborhood. These preventative and proactive security measures would decrease the amount of service calls that APD would otherwise receive. Therefore, the APD can adequately serve the site with respect to police protection and services during operation. 3) Schools The Project is in an area that is currently served by the Savanna School District (SSD) for elementary schools and the Anaheim Union High School District (AUHSD) for the junior high schools and high schools. The Project would construct a 12-unit, small lot single-family residential subdivision, which would increase the student population. It should be noted that State-mandated open enrollment policy enables students anywhere in SSD and AUHSD to apply to any regular, grade-appropriate SSD and AUHSD school with designated “open enrollment” seats. The number of open enrollment seats is determined annually. Each 71 City of Anaheim Police Department, Locations-website: https://www.anaheim.net/363/Locations, accessed: June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-61 individual school is assessed based on the principal’s knowledge of new housing and other demographic trends in the attendance area. Open enrollment seats are granted through an application process that is completed before the school year begins. Students living in a particular school’s attendance area are not displaced by a student requesting an open enrollment transfer to that school. To reduce any potential population growth impacts on public schools, the governing board of any school district is authorized to levy a fee, charge, dedication, or other requirement against any construction within the boundaries of the district for the purpose of funding the construction or reconstruction of facilities (pursuant to California Education Code Section 17620(a)(1)). The Developer Fee Justification Studies for SSD and AUHSD were both prepared to support the school district’s levy of the fees authorized by Section 17620 of the California Education Code. The Project would be required to pay the appropriate fees, based on the square footage, to both SSD and AUHSD. The Leroy F. Greene School Facilities Act of 1998 (SB 50) sets a maximum level of fees a developer may be required to pay to address a project’s impacts on school facilities. The maximum fees authorized under SB 50 apply to zone changes, general plan amendments, zoning permits, and subdivisions. SB 50 is deemed to fully address school facilities impacts, notwithstanding any contrary provisions in CEQA or other State or local law. Therefore, the site can be adequately served by SSD and AUHSD with respect to schools and education. 4) Parks and Recreation The City of Anaheim Parks Division of the Community Services Department is responsible for the maintenance and upkeep of nearly 800 acres that make up the 57 parks in the City.72 The following parks and recreational facilities are available to serve the Project Site:73 • Twila Reid Park, located at 3100 W. Orange Avenue • Hansen Park, located at 3347 W. Thornton Avenue • John Beat Park, located at 6660 Mt. Shasta Circle • Schweitzer Park, located at 238 S. Belair Street The Project would construct a 12-unit, small lot single-family residential subdivision. To help alleviate the burden on existing park and recreational facilities, the Project would provide open space for Project residents at each single-family home. Even so, the Project would result in an increase in the use of parks and recreational facilities that may not have the capacity to serve residents. Therefore, the City requires the payment of the park fees for residential projects. The City would collect these park fees based on their current rate and fee schedule. The City requires park fees to reduce the park- and open space-related impacts of new residential development 72 City of Anaheim Community Services Department-Parks & Facilities-website: https://www.anaheim.net/916/Parks-Facilities, accessed: June 2021. 73 Ibid. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-62 projects and requires payment of these fees prior to issuance of Certificate of Occupancy. Therefore, the site can be adequately served by Anaheim Parks Division of the Community Services Department with respect to parks and recreation. 5) Libraries Anaheim Public Library (APL) provides library services to the City. The APL system includes a network of seven library branches serving the City of Anaheim and surrounding communities, a Mobile Library (Bookmobile), a book vending machine at the Anaheim Regional Transportation Intermodal Center (ARTIC) transportation center and the Anaheim Heritage Center with the historical Founders Park.74 Essentially, the provision of library services is the responsibility of local government, typically financed through the City general funds. The APL also receives additional funding through donations to the Library Foundation. Regardless, the City would continue to maintain the library’s existing service levels with the Project without an additional library or alterations to the existing libraries. Therefore, APL can serve this the site with respect to libraries. 6) Summary As demonstrated above, the Project would be adequately served by all required utilities and public services, the Project meets this condition. 4. CONCLUSION OF CLASS 32 CATEGORICAL EXEMPTION CONDITIONS CONSISTENCY The Project meets all five conditions enumerated for a Class 32 Categorical Exemption under CEQA. a) Exceptions to a Categorical Exemption [State CEQA Guidelines Section] 15300.2. Exceptions (a) Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located – a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply all instances, except where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies. 74 City of Anaheim Community Services Department-Libraries-About-website: http://www.anaheim.net/1222/About, accessed: June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-63 (b) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant. (c) Significant Effect. A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances. (d) Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR. (e) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code. (f) Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-64 (g) b) Project Analysis Exception (a): Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located – a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply all instances, except where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies. This exception does not apply to the Project as the Project is seeking Class 32 Categorical Exemption. Nonetheless, the Project would not affect an environmental resource of hazardous or critical concern (see also the discussion for Exception [e]), below). As discussed under Condition (C), above, the Project Site does not contain any habitat capable of sustaining any species identified as endangered, rare, or threatened. Therefore, the exception is not applicable to the Project. Exception (b): Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant. Cumulative impacts are two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts (State CEQA Guidelines Section 15355). Cumulative impacts may be analyzed by considering a list of past, present, and probable future projects producing related or cumulative impacts (State CEQA Guidelines Section 15130[b][1][A]). An overview of each impact discussion is provided below, and as shown, the Project would not result in any Project-specific significant impacts and would not have any impacts that are individually limited but cumulatively considerable. 1) Local Land Use Plans and Zoning Development of related projects would occur in accordance with adopted plans and regulations. Most of related projects would be compatible with the zoning and land use designations of each related project site and its existing surrounding uses. In addition, it is reasonable to assume that related projects under consideration in the surrounding area would implement and support local and regional planning goals and policies. Therefore, cumulative land use impacts would be less than significant. 2) Endangered, Rare, or Threatened Species The Project Site is located in an urbanized area and does not consist of any endangered, rare, or threatened species. However, it is unknown whether or not any of the properties on which related projects may be located contain biological resources, such as sensitive species listed at the federal or State level as endangered, rare, or threatened. Nonetheless, as the Project would not result in a potentially significant impact to listed species or habitat, there is no potential for the Project to contribute to a cumulative impact. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-65 3) Transportation With respect to construction traffic, it is unknown whether any related projects would have overlapping construction schedules with the Project. However, similar to the Project, and pursuant to existing City regulations and policies, related projects would be required to submit formal construction staging and traffic control plans for review and approval by the City prior to the issuance of construction permits. These plans, identified as a Work Area Traffic Control Plan herein, would identify all traffic control measures, signs, delineators, and work instructions through the duration of construction activities. Related projects would comply with this requirement, similar to the Project, and as such, cumulative construction traffic impacts would be less than significant. With respect to cumulative operational traffic impacts, analyses should consider both short-term and long-term project effects on VMT. This document analyzed short-term effects in the project- level VMT analysis summarized above. Long-term, or cumulative, effects are determined through a consistency check with the 2020-2045 RTP/SCS. The 2020-2045 RTP/SCS is the regional plan that demonstrates compliance with air quality conformity requirements and greenhouse gas (GHG) reduction targets. As such, projects that are consistent with this plan, such as the Project, in terms of development, location, density, and intensity, are part of the regional solution for meeting air pollution and GHG goals. Projects deemed consistent would have a less than significant cumulative impact on VMT. Furthermore, the Project would not result in significant VMT impacts to the surrounding transportation system. Therefore, as no VMT analysis was required for the Project, the Project would not make a cumulatively considerable contribution to operational traffic impacts. As such, cumulative operational transportation impacts would be less than significant. 4) Noise Development of the Project in combination with related projects in ¼ mile of the Project Site could result in an increase in construction noise in an already urbanized area of the City. With respect to construction impacts, it is unknown whether any potential nearby projects would have overlapping construction schedules with the Project. However, as with the Project, any nearby project built simultaneously with the Project would be required to meet the same Code requirements regarding construction noise levels. Specifically, construction of all projects would be subject to Code Section 6.72, which limits the hours of allowable construction activities. In addition, each project would be subject to Code Section 6.70, which prohibits any powered equipment or powered hand tool from producing noise levels that exceed 60 dBA for extended periods of time. To comply with this standard, nearby development projects, much like the Project, would implement best practices and/or project design features to reduce construction noise levels. Accordingly, while concurrent construction of nearby projects in ¼ mile of the Project Site could potentially contribute to cumulative increases in ambient noise levels, the Project would not result in any significant construction noise increases, and, thus, it would not result in a cumulatively considerable contribution to any such increase. Therefore, potential construction-related noise impacts would not be significant. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-66 Cumulative noise impacts would occur primarily because of increased traffic on local roadways due to the Project and related projects within the study area. The trip generation potential of the Project is approximately 113 daily trips, with 9 trips (2 inbound, 7 outbound) produced in the AM peak hour and 12 trips (8 inbound, 4 outbound) produced in the PM peak hour on a “typical” weekday. As a result, based on the nominal AM peak hour trip generation and nominal PM peak hour trip generation increase with the Project (i.e. < 50 peak hour trips), the Project is not anticipated to make a cumulatively considerable contribution to a cumulative noise impact associated traffic noise sources. In addition to cumulative mobile source noise levels, operation of the Project in combination with other projects that could develop nearby could result in an increase in operational noise in this urbanized area of the City. However, as described above, long-term noise impacts from Project operations would be negligible, as building operations and human activities inside and outside the Project would generate minimal noise impacts. Moreover, as with the Project, other developments in ¼ mile of the Project would be required to comply with the City’s extensive regulatory requirements that limit operational noise sources to minimal levels. Accordingly, as the Project would not produce any significant operational noise impacts, it would not result in a cumulatively considerable contribution to any significant operational noise impacts. As such, cumulative on- site operational noise impacts would be less than significant. 5) Air Quality SCAQMD recommends that any construction-related emissions and operational emissions from individual development projects that exceed the project-specific mass daily emissions thresholds identified above also be cumulatively considerable. Individual projects that generate emissions not in excess of SCAQMD’s significance thresholds would not contribute considerably to any potential cumulative impact. SCAQMD neither recommends quantified analyses of the emissions generated by a set of cumulative development projects nor provides thresholds of significance to assess the impacts associated with these emissions. As described above, the Project does not generate any regional or localized emissions that exceed SCAQMD’s thresholds; therefore, the Project would not contribute a cumulatively considerable increase in emissions for the pollutants, which the Basin is in nonattainment, and cumulative air quality impacts would be less than significant. 6) Greenhouse Gases Although the Project would emit GHGs, the emission of GHGs by a single project into the atmosphere is not necessarily an adverse environmental effect. As discussed in CEQA case law,75 the global scope of climate change and the fact that carbon dioxide and other GHGs, once released into the atmosphere, are not contained in the local area of their emission means that the impacts to be evaluated are also global rather than local. For many air pollutants, the significance of their environmental impact may depend greatly on where they are emitted; for GHGs, it does not. 75 Supreme Court of California, Center for Biological Diversity et al. v. California Department of Fish and Wildlife (2015), S217763, 11-13. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-67 For individual developments, like the Project, this fact gives rise to an argument that a certain amount of GHG emissions is as inevitable as population growth. Under this view, a significance criterion framed in terms of efficiency is superior to a simple numerical threshold because CEQA is not a population control measure. Meeting statewide reduction goals does not preclude all new development. Rather, the Scoping Plan, the State’s roadmap for meeting AB 32’s target, assumes continued growth and depends on increased efficiency and conservation in land use and transportation from all Californians. To the extent, a project incorporates efficiency and conservation measures sufficient to contribute its portion of the overall GHG reductions necessary; one can reasonably argue that the Project’s impact is not cumulatively considerable, because it is helping to solve the cumulative problem of GHG emissions as envisioned by California law. As discussed above, the Project would reduce GHGs in a manner consistent with applicable regulatory plans and policies to reduce GHG emissions, including AB 32 Scoping Plan, and SCAG’s 2020-2045 RTP/SCS. Similar to the Project, all future projects in the State are subject to review for consistency with applicable State, regional and local plans, policies, or regulations for the reduction of GHGs. Therefore, based on the discussion above, and consistent with State CEQA Guidelines Section 15064(h)(3), the Project’s generation of GHG emissions would not be cumulatively considerable because the Project would not conflict with an applicable plan, policy, or regulation for the purposes of reducing the emissions of GHGs. Therefore, the Project’s contribution to cumulative impacts to GHGs would not be cumulative considerable, and cumulative impacts would be less than significant. 7) Water Quality With respect to construction impacts, it is unknown whether any related projects would have overlapping construction schedules with the Project. However, similar to the Project, related projects would be required to comply with the City Building Code, NPDES requirements, etc. Assuming compliance with these regulatory requirements, similar to the Project, the cumulative water quality impact during construction would be less than significant. With respect to operational impacts, development of the Project in combination with related projects would result in the further infilling in an already developed area. The existing City storm drain system would continue to serve the Project Site and the surrounding area. Runoff from the Project Site and the adjacent land uses is directed into the adjacent streets, where it flows to the drainage system. It is likely that most, if not all, related projects would also drain to the surrounding street system or otherwise retain stormwater on-site as all projects would comply with existing stormwater/LID requirements, which would ensure impacts are less than significant. The capture of runoff associated with related projects would occur in either non-erosive drainage devices to landscaped areas or an existing storm drain system and would not encounter exposed soils. Related projects would include a drainage system with pipes that would adequately convey surface water runoff into the existing storm drain or the on-site cisterns. Additionally, related projects would be required to implement BMPs and to conform to the existing NPDES water quality program. Therefore, cumulative hydrology and water quality impacts during operation would be less than significant. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-68 8) Utilities (a) Water Implementation of the Project in combination with related projects within the service area of OCWD would generate demand for additional water supplies. In terms of the City’s overall water supply condition, the adopted 2015 UWMP accounts for water demand for any project that is consistent with the City’s General Plan and long-range SCAG growth projections. The 2015 UWMP anticipates that the future water supplies would be sufficient to meeting existing and planned growth in the City to the year 2040 (the planning horizon required of 2015 UWMPs) under wet and dry year scenarios. The Project is consistent with the site’s General Plan land use designation, as well as SCAG growth projections, and, therefore, has been accounted for in the 2015 UWMP and its water demand would not be cumulatively considerable. Related projects, as well as other development in the OCWD service area, would be required to comply with current Green Building Code requirements to conserve water, and, in addition, larger projects with over 500 residential units would have to prepare a Water Supply Assessment (pursuant to SB 610) to be reviewed and certified by OCWD to demonstrate adequate water supply. Therefore, because the 2015 UWMP forecasts adequate water supplies to meet all projected water demands in the City through the year 2040, this analysis does not anticipate cumulative impacts with respect to water supply from the development of the Project and related projects. Development of the Project and future new development in ¼ mile of the Project Site would cumulatively increase demands on the existing water infrastructure system. Similar to the Project, related projects would be subject to APUD review to assure the existing public infrastructure would be adequate to meet the domestic and fire water demands of each project and individual projects would be subject to APUD and City requirements regarding infrastructure improvements needed to meet respective water demands, flow and pressure requirements. Furthermore, APUD through the five year updates of the 2015 UWMP and the AFD project specific checks would conduct on-going evaluations of its infrastructure. Therefore, the cumulative impact would be less than significant. (b) Wastewater Implementation of the Project in combination with related projects within the service area of the Reclamation Plant No. 1 and Reclamation Plant No. 2 would generate the demand for treatment of additional wastewater. Currently, the remaining capacity at Reclamation Plant No. 1 is approximately 61 million gpd or approximately 34 percent of its total capacity, and the remaining capacity at Reclamation Plant No. 2 is approximately 60 million gpd or approximately 40 percent of its total capacity.76 Therefore, both treatment plants would have adequate capacity to serve the additional wastewater demanded by the Project and, as such, the Project’s demand would not be cumulatively considerable. With respect to wastewater infrastructure, the City’s Public Works Department assesses the anticipated wastewater flows from development projects at the time of connection and makes the 76 Orange County Sanitation District, Budget Update, Fiscal Year 2019-2020. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-69 appropriate decisions on how best to connect to the local sewer lines at the time of construction. The applicants of related projects would be required to submit a Sewer Capacity Availability Request to verify the anticipated sewer flows and points of connection and to assess the condition and capacity of the sewer lines receiving additional sewer flows from the Project and other cumulative development projects. If it is determined that the sewer system in the local area has insufficient capacity to serve a particular development, the developer of that project would be required to replace or build new sewer lines to a point in the sewer system with sufficient capacity to accommodate that project’s increased flows. Each project would be evaluated on a case-by- case basis and comply with all applicable City and State water conservation programs and sewer allocation ordinances. Therefore, the cumulative impact would be less than significant. (c) Solid Waste Implementation of the Project in combination with related projects within the Southern California region, serviced by area landfills, would increase regional demands on landfill capacities. Construction of the Project and related projects generate construction and demolition waste, resulting in a cumulative increase in the demand for inert (unclassified) landfill capacity. The Project and all other future cumulative development would be required to implement a construction waste management plan to achieve a minimum 75 percent diversion from landfills. Furthermore, as described above, the Olinda Alpha, Frank R. Bowerman, and Prima Deshecha Landfills all have sufficient capacity to accommodate the Project, and, as such, the Project’s demand would not be cumulatively considerable. Therefore, cumulative impacts from demolition and construction waste would be less than significant. Operation of the Project in conjunction with related projects would generate municipal solid waste and result in a cumulative increase in the demand for waste disposal capacity at Class III landfills. The County Integrated Waste Management Plan Annual Report evaluates countywide demand for landfill capacity. Each Annual Report assesses future landfill disposal needs over a 10-year planning horizon. As such, the 2019 Annual Report projects waste generation and available landfill capacity through 2029. Based on the 2019 Annual Report, Orange County has the projected disposal capacity through 2029.77 The Project’s increase in operational solid waste generation, in conjunction with related projects, would represent an insignificant portion of the estimated approximately 2.44 million tons that is anticipated to be generated in 2024 (Project build-out year). 78 The County would continually address landfill capacity through the preparation of Annual Reports. The preparation of each Annual Report provides sufficient lead time (10 years) to address potential future shortfalls in landfill capacity. Moreover, a State-mandated 75 percent landfill diversion rate is required by 2020, which would reduce the amount of solid waste landfilled for related projects. Therefore, cumulative impacts from operational solid waste would be less than significant. 77 Orange County Waste & Recycling, 2019 Annual Report. 78 Ibid. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-70 (d) Natural Gas Implementation of the Project, in conjunction with related projects, would increase demands for natural gas. The State Building Energy Efficiency Standards, embodied in Title 24 of the California Code of Regulations, regulates energy consumption by new buildings in California. The efficiency standards apply to new construction of both residential and non-residential buildings and regulate insulation, glazing, lighting, shading, and water- and space-heating systems. Local jurisdictions enforce these building efficiency standards through the local building permit process. Similar to the Project, related projects and future development must also abide by the same statues, regulations, and programs that mandate or encourage energy conservation. SCG is also required to plan for necessary upgrades and expansion to its systems to ensure that it would provide adequate service for other projects. Specifically, SCG regularly updates its infrastructure reports as required by law. Development projects within the SCG service area would incorporate site-specific infrastructure improvements, as appropriate. Therefore, cumulative impacts are less than significant. (e) Electrical Power Implementation of the Project, in conjunction with related projects, would increase demands for electrical power. As discussed above, APU utilizes renewable energy sources and is committed to meeting the requirement of the RPS Enforcement Program to use at least 33 percent of the State’s energy from renewables by 2020. State law requires all new development in California to be designed and constructed in conformance with State Building Energy Efficiency Standards outlined in Title 24. It is possible that implementation of related projects could require the removal of older structures that were not designed and constructed to conform to the more recent and stringent energy efficiency standards. Thus, it is possible that with implementation of related projects that the resulting demands for electricity supply could be the same or less than the existing condition. Nonetheless, the IRP considers a 20-year planning horizon to guide APUD as it executes major new and replacement projects and programs. The estimated power requirement for related projects would be part of the total load growth forecast for the City and accounted for in the planned growth of power system. APUD undertakes expansion or modification of electrical service infrastructure and distribution systems to serve future growth in the City as required in the normal process of providing electrical service. The APUD addresses any potential cumulative impacts related to electric power service through this process. Electrical service to related projects would also be in accordance with the APUD rules and regulations. Therefore, cumulative impacts related to electricity supply and infrastructure would be less than significant. 9) Public Services (a) Fire Protection Development of the Project in combination with related projects would cumulatively increase the demand for fire protection services. Over time, AFR would continue to monitor population growth and land development throughout the City and identify additional resource needs including staffing, equipment, trucks and engines, ambulances, other special apparatuses, and possibly station expansions or new station construction that may become necessary to achieve the desired level of service. The City’s regular budgeting efforts identify AFR’s resource needs and allocate City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-71 funding according to the priorities at the time. Any new or expanded fire station would be funded via existing mechanisms (e.g., property and sales taxes, government funding, and developer fees) to which the Project and cumulative growth would contribute. Moreover, AFR would review all of the cumulative development in order to ensure adequate fire flow capabilities and adequate emergency access. Compliance with AFR, City Building Code, and Fire Code requirements related to fire safety, access, and fire flow would ensure that cumulative impacts to fire protection would be less than significant. (b) Police Protection The Project in combination with related projects would increase the demand for police protection services. This cumulative increase would increase demand for additional APD staffing, equipment, and facilities over time. Similar to the Project, other projects served by APD would implement safety and security features according to APD recommendations. APD would continue to monitor population growth and land development throughout the City and identify additional resource needs including staffing, equipment, vehicles, and possibly station expansions or new station construction that may become necessary to achieve the desired level of service. The City’s regular budgeting efforts would identify APD’s resource needs and allocate funding according to the priorities at the time. Any new or expanded police station would be funded via existing mechanisms (e.g., property and sales taxes, government funding, and developer fees) to which the Project and cumulative growth would contribute. Therefore, the cumulative impact on police protection services would be less than significant. (c) Schools As discussed above, payment of developer impact fees in accordance with SB 50 and pursuant to Section 65995 of the California Government Code would ensure that the impacts of the Project on school facilities would be less than significant. Similar to the Project, related projects would be required to pay school fees to the appropriate school district wherein their site is located. The payment of school fees would fully address any potential impacts to school facilities. Therefore, cumulative impacts would be less than significant. (d) Parks and Recreation As discussed above, the Project would result in a less than significant impact on parks and recreational facilities. Projects that meet the established criteria would be required to pay Parks and Recreation Fees to the City for the construction of residential dwelling units. The payment of fees would address potential impacts to park and recreational facilities. Therefore, the cumulative impact would be less than significant. (e) Libraries Related projects within the City and with a residential component could generate additional residents who could increase the demand upon library services. Population growth affects online resources because the basis for licensing fees for these databases, eBooks, and other digital resources are generally the population of the library’s service area. With additional residents to serve, the Project would reduce the overall availability per capita of books, media, computers, and library public service space. Therefore, in order to maintain current per capita levels and licensing City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-72 agreements, the City would need to provide additional physical and virtual resources to the Anaheim library system. The threshold for determining impacts pursuant to CEQA is based upon whether the project would result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services. The impacts to the overall availability per capita of books, media, computers, and library public service space would not create significant physical or environmental impacts. Therefore, the cumulative impact would be less than significant. 10) Historical Resources See the analysis under Exception (f), below, for Project-specific impacts to historic resources. The Project would not result in a significant impact to historical resources. It is unknown whether any of the properties on which related projects may be located contain historical resources. Any related project sites that contain historical resources would be required to comply with existing regulations and/or safeguard measures as appropriate for that project, including required compliance with CEQA’s provisions regarding historical resources. As the Project would not result in a significant impact to historical resources, there is no potential for the Project to contribute to a cumulative impact, and thus, the cumulative impact would be less than significant. 11) Summary As no cumulatively significant impacts would result from the Project, the exception is not applicable to the Project. Exception (c): Significant Effect. A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances. There are no unusual circumstances with the Project Site or the Project that would create a reasonable possibility of significant effects to the environment. The Project Site is located within an urbanized, residential setting. The Project would replace a single-family use with a 12 unit single-family subdivision. Moreover, the Lead Agency has not determined an unusual circumstance is applicable to the Project. The Project is consistent with the underlying zoning. Moreover, as analyzed in Exception (b), above, the Project would not result in any Project-specific or cumulative traffic, noise, air quality, greenhouse gas, or water quality impacts. The proposed land use is consistent and compatible with the Project Site’s urban, residential setting and is typical for an infill development. Therefore, as there are no unusual circumstances regarding the Project or Project Site, the exception is not applicable to the Project. Exception (d): Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-73 highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR. There are no State-designated scenic highways or highways eligible for scenic designation in the Project Site vicinity.79 There are also no locally-designated scenic highways in the Project Site vicinity.80 There are several ornamental trees growing within the Project Site boundaries. The existing on- site trees, none of which are protected species by the City’s tree protection ordinance, would be removed during construction. While grading for Project would require removal of all on-site trees, the Project proposes to plant approximately 38 trees, of which six would be street trees. See Figure I-14 for the Project’s landscape plan. Therefore, as the Project Site is not located along a State- or City-designated scenic highway and would not damage scenic resources, the exception is not applicable to the Project. Exception (e): Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code. California Government Code Section 65962.5 requires various State agencies to compile lists of hazardous waste disposal facilities, unauthorized releases from underground storage tanks, contaminated drinking water wells, and solid waste facilities where there is known migration of hazardous waste, and submit such information to the Secretary for Environmental Protection on at least an annual basis. A significant impact may occur if a project site is included on any of the above lists and poses an environmental hazard to surrounding sensitive uses. There are no known hazardous sites associated with the Project Site as according to California Department of Toxic Substances Control’s (DTSC) EnviroStor database.81 The Project would not pose an environmental hazard to surrounding sensitive uses or the environment in regards to siting the Project on a known hazardous waste site or any other type of site appearing on a list compiled pursuant to Section 65962.5 of the Government Code, and a less than significant impact would occur. Therefore, as the Project Site is not located on a hazardous waste site and no hazardous materials occur at the Project Site, no potentially significant hazardous impacts would result. This exception is not applicable to the Project. Furthermore, the Project Site is not located in an area where petroleum exploration and production has occurred in the past. The closest oil and/or gas exploration well was located approximately one mile to the west of the Site. This well is now listed as idle. The Project Site is not known to be located within a designated oil field and not in an area where hazards associated with surface 79 CalTrans website, Scenic Highways, https://caltrans.maps.arcgis.com/apps/webappviewer/index.html?id=465dfd3d807c46cc8e8057116f1aacaa, accessed July 2021. 80 City of Anaheim General Plan, Circulation Element, Figure C-3, July 2020. 81 California Department of Toxic Substances Control, EnviroStor, website: https://www.envirostor.dtsc.ca.gov/public/map/?global_id=30880005, accessed: September 2021.

Categorical Exemption Analysis Page II-74 seepage of methane gas from natural or artificial sources have been identified.82 Therefore, as the Project Site is not included on any list compiled pursuant to Section 65962.5 of the Government Code, the exception is not applicable to the Project. Exception (f): Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource. Section 15064.5 of the State CEQA Guidelines defines a historical resource as: (1) A resource listed in or determined to be eligible by the State Historical Resources Commission, for listing in the California Register of Historical Resources; (2) A resource listed in a local register of historical resources or identified as significant in an historical resource survey meeting certain state guidelines; or (3) An object, building, structure, site, area, place, record or manuscript which a lead agency determines to be significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California, provided that the lead agency’s determination is supported by substantial evidence in light of the whole record. A significant adverse effect would occur if a project were to adversely affect an historical resource meeting one of the above definitions. A substantial adverse change in the significance of a historic resource means demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of a historical resource would be materially impaired. The Project Site was recently occupied by a single-family residence, detached garage, swimming pool, asphalt driveway, and other ancillary construction. The residence has recently been demolished and only the swimming pool, portions of the asphalt driveway, and remnant portions of the building foundations remain. The Project Site is bounded on the west by Western Avenue, on the north and east by single-family residences, and to the south by multi-family developments.83 A records search with the South-Central Coast Information Center (SCCIC) of the California Historical Resources Information System (CHRIS) located at California State University (CSU), Fullerton in Fullerton, California was requested in order to assess potential presence of cultural resources within the Project area and a 0.25-mile radius around the Project area. The purpose of the record search was to identify if any prehistoric and/or historic-period cultural resources and studies had been previously documented in the project area and/or the surrounding 0.25-mile radius in order to better understand the archaeological sensitivity of the area. Additionally, a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) was requested to verify that Native American gravesites, tribal resources and other cultural and spiritual sites of 82 Refer to Appendix K, Updated Geotechnical Investigation for Proposed Twelve Single-Family Homes Tentative Tract 17944, 910 South Western Avenue, City of Anaheim, California, prepared by PETRA GeoSciences, June 2021. 83 Refer to Appendix K, Updated Geotechnical Investigation for Proposed Twelve Single-Family Homes Tentative Tract 17944, 910 South Western Avenue, City of Anaheim, California, prepared by PETRA GeoSciences, June 2021. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-75 interests and importance to tribes that are traditionally and culturally affiliated with the Project’s geographic area.84 The SCCIC records search efforts concluded with negative results for previously recorded cultural resources and previously conducted cultural resources studies within the Project area and the 0.25- mile radius. The negative results from the SCCIC indicate the Project area have never been surveyed and therefore it is unknown if archaeological resources are present within the Project area. Additionally, the SLF search resulted positive and the NAHC recommends contacting the Gabrieleno/Tongva San Gabriel Band of Mission Indians. The NAHC also recommended to contact other Native American tribes from the provided contact list who may also have knowledge of cultural resources in the Project area.85 Therefore, the Project Applicant shall obtain the services of a qualified archaeologist to be on-call in the event of any subsurface archaeological materials and provide workers with a one-day training for awareness and procedures to follow in the event of inadvertent findings. The City shall also follow up with the Gabrieleno/Tongva San Gabriel Band of Mission Indians and other Native American tribes to determine if there are any known tribal cultural resources within the Project area and coordinate with the Tribe(s) to develop appropriate conditions, if warranted.86 Based on the proposed activity, which would be the development of the Project upon previously disturbed soils, the area has a low-likelihood for buried cultural resources. However, in the unlikely case the Applicant discovers human remains during ground disturbing activities, California Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the Orange County Coroner has made the necessary findings as to origin. Further pursuant to California Public Health & Safety Code, Section 5097-98(b) remains shall be left in place and free of disturbance until a final decision as the treatment and disposition has been made. If the Orange County Coroner determines the remains to be Native American, the Project Applicant must contact the Native American Heritage Commission within 24 hours. The Native American Heritage Commission must then immediately identify the "most likely descendants(s)" for purposes of receiving notification of discovery. The most likely descendant(s) shall then make recommendations within 48 hours and engage in consultation concerning the treatment of the remains as provided in California Public Resources Code, Section 5097.98. Therefore, implementation of the Project would not result in a substantial adverse change to a historic resource. This exception is not applicable to the Project. 5. CONCLUSION None of the six exceptions to a Categorical Exemption is applicable to this Project. As the Project meets all five conditions enumerated for a Class 32 Categorical Exemption under CEQA and no 84 Refer to Appendix L. Cultural Resources Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California, prepared by Kleinfelder, September 13, 2021. 85 Ibid. 86 Ibid. City of Anaheim Pepperwood Place Project DEV2019-00139 Class 32 Exemption 910 S. Western Avenue Class 32 Exemption II. Categorical Exemption Analysis Page II-76 exceptions are applicable, the Project therefore qualifies for a Categorical Exemption under CEQA. No further analysis is required. DETERMINATION: I find that the answers given above are adequately supported by the information sources cited following each question and that the effects of the Project are typical of those generated within that class of projects (i.e., Class 32 – Infill Development Projects) characterized as in-fill development meeting the conditions of Section 15332 of Title 14 of the California Code of Regulations. The Project will not cause a significant effect on the environment and is, therefore, categorically exempt from the requirement for the preparation of environmental documents under the California Environmental Quality Act.

The desktop review was completed by Kleinfelder biologist Jennifer Kellerman on June 25, 2021. The primary objectives of the desktop review were to: identify known special-status plant and wildlife species within and adjacent to the project area; identify sensitive habitat types; assess the suitability of the site to support special-status species; and to summarize potential biological constraints associated with the proposed development of the site. PROJECT OVERVIEW The proposed project site is located in a developed neighborhood within the City of Anaheim, in Orange County, California (Figure 1). The proposed project site is approximately 0.44-mile west of Highway 39 and 0.39mile south of Carbon Creek, and is located in Township 4 South, Range 11 West, and Section 3 of the Los Alamitos 7.5-minute U.S. Geological Survey (USGS) quadrangle (Figure 2). The proposed project entails development of a 12-unit single-family residential subdivision on approximately 1.39-acres of land located at Assessor’s Parcel Numbers 079-882-36 and 079-882-37. ENVIRONMENTAL SETTING Recent aerial imagery was reviewed to determine land cover types present on the site, including a 500-foot buffer surrounding the site (Google 2021). Aerial imagery shows developed and landscaped land cover types are present within the proposed project site and 500-foot buffer area (Figure 3). Developed habitat is defined as areas with significant human improvements, where native vegetation has been cleared for residential, commercial, industrial, recreational, or transportation purposes. Landscaped habitat typically consists of non-native vegetation planted by humans to increase the aesthetic of an area. Developed and landscaped areas are often dominated by non-native species, resulting in what is considered low-quality habitat for native species. REVIEW METHODS Kleinfelder biologist Jennifer Kellerman conducted a database search and literature review to determine the potential for sensitive biological resources to occur within the proposed project site and a 500-foot buffer surrounding the site. The review focused on special-status plant and wildlife species and sensitive habitat types identified using the following databases: Google Earth (2021), the California Department of Fish and Wildlife’s California Natural Diversity Database (CNDDB), the California Native Plant Society (CNPS) Rare Plant Inventory (RPI), National Wetland Inventory (NWI), and U.S. Fish and Wildlife Service’s Information for Planning and Consultation (IPaC) trust resource report. 20221225.001A Page 2 of 9 The CNDDB and NWI query included the project footprint and a one-mile buffer (CNDDB 2021; ERMA n.d.). The CNPS RPI query consisted of an eight-quadrangle search around the project area; a nine- quadrangle search was not completed as CNPS treats the Long Beach and Long Beach OE S 7.5-minute USGS quadrangles as a single quadrangle (CNPS 2021). A list of special-status plant and wildlife species with potential to occur on the site or within the 500-foot buffer can be found in Appendices A and B. RESULTS Results of the CNDDB and IPaC queries indicated five special-status wildlife species known to occur within the one-mile search area (Appendix A). These included California Least Tern (Sterna antillarum browni), Western Snowy Plover (Charadruis nivosus nivos), Coastal California gnatcatcher (Polioptila californica californica), Pacific Pocket Mouse (Perognathus longimembris pacificus), Western tidal-flat tiger beetle (Habroscelimorpha gabbii). These species require specialized habitat such as coastal sage scrub and coastal environments including open beaches, mudflats, sand dunes, sand spits, lagoons, estuaries, salt marshes, dredged material deposal sites, salt pond levees, dry salt ponds, river alluvium, and river bars (Pearson, D. L., et al. 2015; USFW 2010; USFW 2017; USFW 2021; USFW 2021), which are not present within the proposed project site (Google 2021). While no suitable habitat for these five special-status wildlife species is present within the project site and buffer area, suitable nesting habitat for raptors and native migratory bird species protected by California Fish and Game Code 3503.5 and the Migratory Bird Treaty Act (MBTA) is present within the proposed project site. The proposed project site is surrounded by residential development which suggests human activity in the area is high, resulting in a low likelihood that wildlife species sensitive to human disturbance will be present in or use the study area. The project site and surrounding area is anticipated to support wildlife species that thrive in urban and disturbed habitats, including but not limited to, California ground squirrel (Otospermophilus beecheyi), raccoon (Procyon lotor), American crow (Corvus brachyrhynchos), European starling (Sturnus vulgaris), northern mockingbird (Mimus polyglottos), lesser goldfinch (Carduelis psaltria), rock pigeon (Columba livia), house finch (Passer domesticus), and western fence lizard (Sceloporus occidentalis). Results of the CNPS RPI query indicated 26 special-status plant species known to occur within the eight- quad search area (Appendix B). However, there is no suitable habitat for any of these species within the project site, and the developed and landscaped nature of the project site likely precludes all of these species from occurring on the site. More information regarding this assessment can be found in Appendix B. Results of the NWI query indicated one wetland feature is present within the one-mile search radius. Carbon Creek is located approximately 0.35 miles northwest of the proposed project area (NOAA et al., 2021). Carbon Creek is an intermittent creek with an artificial streambed that does not contain suitable habitat for special status species. This creek connects with the Los Alamitos, a man-made channel, which connects with San Pedro Bay. Compliance with the California Water Boards Construction Stormwater Program would result in less than significant impacts to Carbon Creek and all downstream connecting bodies of water. CONCLUSIONS AND RECOMMENDATIONS Due to the developed and landscaped nature of the project site and surrounding area, no suitable habitat that would support special-status plant or wildlife species, or sensitive habitats protected by CDFW, is present. However, suitable nesting habitat for raptors and native migratory birds is present within and adjacent to the project site. As stated above, the trees surrounding the proposed project site provide suitable nesting habitat for native birds protected by the MBTA and California Fish and Game Code. Therefore, Kleinfelder recommends any vegetation removal or ground disturbance activities occur between September 16 and January 31, 20221225.001A Page 3 of 9 outside of the bird breeding season, which lasts from February 1 to September 15. If the project activities are scheduled to occur during the bird breeding season, Kleinfelder recommends to have a biological monitor with native bird experience to assure no impacts to native nesting birds would occur under the project.

Western Avenue (i.e. generally on the east side of Western Avenue and north of Ball Road), in the City of Anaheim, California. The Project site is currently occupied with a vacant single-family home that will be demolished. The proposed Project will consist of 12 single-family residential dwelling units on a private street with a “hammerhead” turnaround area. The proposed Project is expected to be completed in the Year 2022. Access to the proposed Project site will be provided via one (1) full-access private street driveway along Western Avenue (i.e. Project Access No. 1). ▪ Study Scope – The two (2) key study intersections selected for evaluation were determined based on coordination with City of Anaheim Traffic Engineering Department staff. The two (2) intersections listed below provide regional and local access to the study area and define the extent of the boundaries for this traffic impact investigation. All key study intersections are located within the City of Anaheim. Key Study Intersections 1. Western Avenue at Orange Avenue 2. Western Avenue at Ball Road ▪ Existing Traffic Conditions – The two (2) key study intersections currently operate at acceptable LOS B during the AM and PM peak hours. ▪ Project Trip Generation – The proposed Project is forecast to generate approximately 113 daily trips, with 9 trips (2 inbound, 7 outbound) produced in the AM peak hour and 12 trips (8 inbound, 4 outbound) produced in the PM peak hour on a “typical” weekday. ▪ Cumulative Projects Traffic Characteristics – There are eighteen (18) cumulative projects in the City of Anaheim, three (3) cumulative projects in the City of Buena Park, five (5) cumulative projects in the City of Cypress, eight (8) cumulative projects in the City of Stanton, and one (1) cumulative project in the City of Garden Grove within the vicinity of the subject site. The thirty- five (35) cumulative projects are forecast to generate a total of 22,368 daily trips, with 1,154 trips (463 inbound and 691 outbound) forecast during the AM peak hour and 1,479 trips (824 inbound and 655 outbound) forecast during the PM peak hour. ▪ Existing Plus Cumulative Plus Project Traffic Conditions – The proposed Project will not cause an operational deficiency at either of the two (2) key study intersections when compared to the LOS standards and traffic impact criteria specified in this report. The two (2) key study intersections are forecast to continue to operate at an acceptable LOS C or better during the AM and PM peak hours with the addition of project generated traffic to existing traffic and cumulative traffic. LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc vii ▪ Year 2022 Cumulative Plus Project Traffic Conditions – The proposed Project will not cause an operational deficiency at either of the two (2) key study intersections when compared to the LOS standards and traffic impact criteria specified in this report. The two (2) key study intersections are forecast to continue to operate at an acceptable LOS C or better during the AM and PM peak hours with the addition of project generated traffic in the Year 2022. ▪ Site Access Evaluation – The proposed Project access is forecast to operate at LOS C or better during the AM and PM peak hours under Year 2022 Cumulative Plus Project traffic conditions. As such, Project access will be adequate. Motorists entering and exiting the Project site will be able to do so without undue congestion. The on-site circulation layout of the proposed Project as illustrated in Figure 2-2 on an overall basis is adequate. Curb return radii are generally adequate for small service/delivery (FedEx, UPS) trucks and trash trucks. ▪ Sight Distance Evaluation – The sight lines at Project Access No. 1 are expected to be adequate provided obstructions within the sight triangles are minimized. In addition, any future landscaping and/or hardscapes (i.e. monument signs) should be designed such that a driver’s clear line of sight is not obstructed. ▪ Recommended Improvements – The results of the intersection capacity analysis shows that the proposed Project will not cause an operational deficiency at the two (2) key study intersections under the “Existing Plus Cumulative Plus Project” and “Year 2022 Plus Project” traffic scenarios. Given that there are no Project impacts, no improvements are required of the proposed project. ▪ Congestion Management Program (CMP) – The CMP requires that a traffic impact analysis be conducted for any project generating 2,400 or more daily trips, or 1,600 or more daily trips for projects that directly access the CMP Highway System (HS). As noted in Section 5.0 of this traffic study, the proposed Project is forecast to generate approximately 113 daily trip-ends and thus does not meet the criteria requiring a CMP TIA. LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc 1 REVISED TRAFFIC IMPACT ANALYSIS PEPPERWOOD PLACE PROJECT June 15, 2021 (Revision of the February 11, 2021 Report) 1.0 INTRODUCTION This traffic impact analysis addresses the potential traffic impacts and circulation needs associated with the Pepperwood Place Project (hereinafter referred to as Project). The proposed Project will consist of 12 single-family residential dwelling units on a private street with a “hammerhead” turnaround area. The proposed Project is expected to be completed in the Year 2022. The proposed project site is located at 910 S. Western Avenue (i.e. generally on the east side of Western Avenue and north of Ball Road), in the City of Anaheim, California. The Project site is currently occupied with a vacant single-family home that will be demolished. This report documents the findings and recommendations of a traffic impact analysis conducted by Linscott, Law & Greenspan, Engineers (LLG) to determine the potential impacts associated with the Project. The traffic analysis evaluates the existing operating conditions at two (2) key study intersections within the project vicinity, estimates the trip generation potential of the Project, and forecasts future operating conditions without and with the proposed Project. Where necessary, intersection improvements/mitigation measures are identified. This traffic report satisfies the City of Anaheim Criteria for Preparation of Traffic Impact Studies and is consistent with the requirements and procedures outlined in the most current Congestion Management Program (CMP) for Orange County. The Scope of Work for this traffic study, which is included in Appendix A, was developed in conjunction with City of Anaheim Traffic Engineering Department staff. The project site has been visited and an inventory of adjacent area roadways and intersections was performed. Existing traffic information has been collected at two (2) key study intersections on a “typical” weekday for use in the preparation of intersection level of service calculations. Information concerning cumulative projects (planned and/or approved) in the vicinity of the proposed Project has been researched at the City of Anaheim, the City of Buena Park, the City of Cypress, the City of Stanton, and the City of Garden Grove. Based on our research, there are eighteen (18) cumulative projects in the City of Anaheim, three (3) cumulative projects in the City of Buena Park, five (5) cumulative projects in the City of Cypress, eight (8) cumulative projects in the City of Stanton, and one (1) cumulative project in the City of Garden Grove within the vicinity of the subject site. These thirty-five (35) planned and/or approved cumulative projects were considered in the cumulative traffic analysis for this project. This traffic report analyzes existing and future weekday AM peak hour and PM peak hour traffic conditions for a near-term (Year 2022 – Project Opening Year) traffic setting upon completion of the proposed Project. Peak hour traffic forecasts for the Year 2022 horizon year have been projected by LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc 2 increasing existing traffic volumes by an annual growth rate of one percent (1.0%) per year and adding traffic volumes generated by thirty-five (35) cumulative projects. 1.1 Study Area The two (2) key study intersections selected for evaluation were determined based on coordination with City of Anaheim Traffic Engineering Department staff. The two (2) intersections listed below provide regional and local access to the study area and define the extent of the boundaries for this traffic impact investigation. All key study intersections are located within the City of Anaheim. Key Study Intersections 1. Western Avenue at Orange Avenue 2. Western Avenue at Ball Road Figure 1-1 presents a Vicinity Map, which illustrates the general location of the proposed Project and depicts the study locations and surrounding street system. The Level of Service (LOS) investigations at these key locations were used to evaluate the potential traffic-related impacts associated with area growth, cumulative projects and the proposed Project. When necessary, this report recommends intersection improvements that may be required to accommodate future traffic volumes and restore/maintain an acceptable Level of Service and/or mitigate the impact of the project. Included in this Traffic Impact Analysis are: ▪ Existing traffic counts, ▪ Estimated project traffic generation/distribution/assignment, ▪ Estimated cumulative project traffic generation/distribution/assignment, ▪ AM and PM peak hour capacity analyses for existing conditions, ▪ AM and PM peak hour capacity analyses for existing plus cumulative conditions without and with project traffic, ▪ AM and PM peak hour capacity analyses for future (Year 2022) conditions without and with project traffic, ▪ Site Access Evaluation, ▪ Recommended Improvements, and ▪ Congestion Management Program (CMP) Analysis.

The proposed Project will consist of 12 single-family residential dwelling units on a private street with a “hammerhead” turnaround area. The proposed Project is expected to be completed in the Year 2022. Figure 2-2 presents the proposed site plan for the proposed Project. 2.1 Site Access As shown in Figure 2-2, access to the proposed Project site will be provided via one (1) full-access private street driveway along Western Avenue (i.e. Project Access No. 1). 12P-66.54,322 S.F.2P-66.53,771 S.F.3P-66.23,861 S.F.4P-66.03,865 S.F.5P-66.03,869 S.F.6P-66.23,666 S.F.11P-66.53,751 S.F.10P-66.23,832 S.F.9P-66.03,829 S.F.8P-66.03,825 S.F.7P-66.23,463 S.F.12'9'15' 15.1' 15.2' 15.2' 15.3' 10.5' 15' 15' 15'5'5'8.5'18' 18' 18' 18' 17' 25' 11' 24'5'17'5'5'17'8.5'15.8' 15.8' 15.7' 15.7' 10.5' 18' 18' 15' 15' 18'1P-66.54,336 S.F.275.5'275.5'219.0' 73.6'50.0'44.0'44.0'44.0'44.0'49.5'76.1' 86.0' 85.9' 85.8' 85.8' 85.7'43.0'44.0'44.0'44.0'44.0'21.33'13.0'26.5'73.4'43.0'44.0'44.0'44.0'44.0'21.33'13.0'28'68.9' 84.9' 85.0' 85.1' 85.2' 85.3'50.0'44.0'44.0'44.0'44.0'49.5'10' 10' 10' 10' 10' 80'28'15' 18' 10' 18' 15' 10' 18' 15' 10'FHFH5'5'5'5'5'5'5'5'5'5'5'5'5'5'5'5' LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc 4 3.0 EXISTING CONDITIONS 3.1 Existing Street System The principal local network of streets serving the proposed Project includes Western Avenue, Orange Avenue, and Ball Road. The following discussion provides a brief synopsis of these key area streets. The descriptions are based on an inventory of existing roadway conditions. Western Avenue is a four-lane, divided roadway oriented in the north-south direction, bordering the project site to the west. On-street parking is generally not permitted along this roadway within the vicinity of the Project, except for south of Faircrest Drive on the west side of the roadway. The posted speed limit on Western Avenue is 40 miles per hour (mph). A traffic signal controls the study intersections of Western Avenue at Orange Avenue and Ball Road. Orange Avenue is a four-lane, divided roadway oriented in the east-west direction, located north of the Project site. On-street parking is generally permitted along this roadway, west of Western Avenue and not permitted along this roadway east of Western Avenue. The posted speed limit on Orange Avenue is 40 mph. Ball Road is generally a four-lane, divided roadway oriented in the east-west direction. On-street parking is generally permitted along this roadway within the vicinity of the Project. The posted speed limit on Ball Road is 40 mph. Figure 3-1 presents an inventory of the existing roadway conditions for the arterials and intersections evaluated in this report. This figure identifies the number of travel lanes for key arterials, as well as intersection configurations and controls for the key area study intersections. 3.2 Existing Traffic Volumes Due to the State of California “Stay at Home” order as a result of the COVID-19 Coronavirus Pandemic, historical counts were researched for the two (2) key study intersections evaluated in this report. Specifically, the historical traffic counts for intersection #1 and #2 were conducted by Counts Unlimited on December 10, 2019. The traffic counts for intersection #1 and #2 were factored up by the City-approved growth factor of 1.0% per year to reflect current Year 2021 existing baseline traffic conditions (i.e. 2% total growth). Figures 3-2 and 3-3 illustrate the existing AM and PM peak hour traffic volumes at the three (3) key study intersections evaluated in this report, respectively. Appendix B contains the historical detailed peak hour traffic count sheets for the key intersections evaluated in this report. 3.3 Existing Intersection Conditions Existing AM and PM peak hour operating conditions for the two (2) key study intersections were evaluated using the Intersection Capacity Utilization (ICU) methodology for signalized intersections and the methodology outlined in the Highway Capacity Manual (HCM) for unsignalized intersections. LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc 5 3.3.1 Intersection Capacity Utilization (ICU) Method of Analysis (Signalized Intersections) In conformance with the City of Anaheim, existing AM and PM peak hour operating conditions for the key signalized study intersections were evaluated using the Intersection Capacity Utilization (ICU) method. The ICU technique is intended for signalized intersection analysis and estimates the volume to capacity (V/C) relationship for an intersection based on the individual V/C ratios for key conflicting traffic movements. The ICU numerical value represents the percent signal (green) time and thus capacity, required by existing and/or future traffic. It should be noted that the ICU methodology assumes uniform traffic distribution per intersection approach lane and optimal signal timing. Per City of Anaheim requirements, the ICU calculations use a lane capacity of 1,700 vehicles per hour (vph) for through and all turn lanes. A clearance adjustment factor of 0.05 was added to each Level of Service calculation. The ICU value translates to a Level of Service (LOS) estimate, which is a relative measure of the intersection performance. The ICU value is the sum of the critical volume to capacity ratios at an intersection; it is not intended to be indicative of the LOS of each of the individual turning movements. The six qualitative categories of Level of Service have been defined along with the corresponding ICU value range and are shown in Table 3-1. 3.3.2 Highway Capacity Manual 6 (HCM 6) Method of Analysis (Unsignalized Intersections) The HCM unsignalized methodology for stop-controlled intersections was utilized for the analysis of the unsignalized intersections (i.e. proposed Project Access). This methodology estimates the average control delay for each of the subject movements and determines the level of service for each movement. For all-way stop controlled intersections, the overall average control delay measured in seconds per vehicle, and level of service is calculated for the entire intersection. For one-way and two-way stop-controlled (minor street stop-controlled) intersections, this methodology estimates the worst side street delay, measured in seconds per vehicle and determines the level of service for that approach. The HCM control delay value translates to a Level of Service (LOS) estimate, which is a relative measure of the intersection performance. The six qualitative categories of Level of Service have been defined along with the corresponding HCM control delay value range, as shown in Table 3-2. 3.4 Level of Service Criteria According to the City of Anaheim’s Circulation Element and stated in the City of Anaheim Criteria for Preparation of Traffic Impact Studies, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all City intersections. 3.5 Existing Level of Service Results 3.5.1 Intersections Table 3-3 summarizes the existing peak hour service level calculations for the two (2) key study intersections based on existing traffic volumes and current street geometry.

The first step is trip generation, which estimates the total arriving and departing traffic on a peak hour and daily basis. The traffic generation potential is forecast by applying the appropriate vehicle trip generation equations or rates to the project development tabulation. The second step of the forecasting process is trip distribution, which identifies the origins and destinations of inbound and outbound project traffic. These origins and destinations are typically based on demographics and existing/anticipated travel patterns in the study area. The third step is traffic assignment, which involves the allocation of project traffic to study area streets and intersections. Traffic assignment is typically based on minimization of travel time, which may or may not involve the shortest route, depending on prevailing operating conditions and travel speeds. Traffic distribution patterns are indicated by general percentage orientation, while traffic assignment allocates specific volume forecasts to individual roadway links and intersection turning movements throughout the study area. With the forecasting process complete and project traffic assignments developed, the impact of the proposed Project is isolated by comparing operational (LOS) conditions at selected key intersections using expected future traffic volumes with and without forecast project traffic. The need for site- specific and/or cumulative local area traffic improvements can then be evaluated and the significance of the project’s impacts identified. LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2.20.4355.1 Pepperwood Place Project, Anaheim N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place Revised TIA 06-15-21.doc 11 5.0 PROJECT TRAFFIC CHARACTERISTICS 5.1 Project Traffic Generation Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular movements, either entering or exiting the generating land use. Generation equations and/or rates used in the traffic forecasting procedure are found in the 10th Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE) [Washington D.C., 2017]. Table 5-1 summarizes the trip generation rates used in forecasting the vehicular trips generated by the proposed Project and also presents the forecast daily and peak hour project traffic volumes for a “typical” weekday. As shown in the middle portion of Table 5-1, the trip generation potential for the proposed Project was estimated using ITE Land Use 210: Single-Family Detached Housing trip rates. Review of the lower portion of Table 5-1 indicates that the proposed Project is forecast to generate approximately 113 daily trips, with 9 trips (2 inbound, 7 outbound) produced in the AM peak hour and 12 trips (8 inbound, 4 outbound) produced in the PM peak hour on a “typical” weekday. 5.2 Project Traffic Distribution and Assignment Figure 5-1 presents the traffic distribution pattern for the proposed Project. Project traffic volumes both entering and exiting the site have been distributed and assigned to the adjacent street system based on the following considerations: ▪ the site's proximity to major traffic carriers (i.e. Western Avenue, Orange Avenue, Ball Road, etc.), ▪ expected localized traffic flow patterns based on adjacent street channelization and presence of traffic signals, ▪ existing intersection traffic volumes, and ▪ ingress/egress availability at the project site. The anticipated AM and PM peak hour traffic volumes associated with the Project are presented in Figures 5-2 and 5-3, respectively. The traffic volume assignments presented in Figures 5-2 and 5-3 reflect the traffic distribution characteristics shown in Figure 5-1 and the traffic generation forecast presented in Table 5-1.

The ambient traffic growth factor is intended to include unknown and future cumulative projects in the study area, as well as account for regular growth in traffic volumes due to the development of projects outside the study area. The future growth in traffic volumes has been calculated at one percent (1.0%) per year. Applied to the Year 2021 existing traffic volumes, this factor results in a 1.0% growth in existing volumes to the near-term horizon Year 2022. 6.2 Cumulative Projects Traffic Characteristics In order to make a realistic estimate of future on-street conditions prior to implementation of the proposed Project, the status of other known development projects (cumulative projects) in the vicinity of the proposed Project has been researched at the City of Anaheim, the City of Buena Park, the City of Cypress, the City of Stanton, and the City of Garden Grove. With this information, the potential impact of the proposed Project can be evaluated within the context of the cumulative impact of all ongoing development. Based on our research, there are eighteen (18) cumulative projects in the City of Anaheim, three (3) cumulative projects in the City of Buena Park, five (5) cumulative projects in the City of Cypress, eight (8) cumulative projects in the City of Stanton, and one (1) cumulative project in the City of Garden Grove within the vicinity of the subject site. These thirty-five (35) planned and/or approved cumulative projects were considered in the cumulative traffic analysis for this project. Table 6-1 provides a brief description for each of the thirty-five (35) cumulative projects. Figure 6-1 graphically illustrates the location of the cumulative projects. These cumulative projects are expected to generate vehicular traffic, which may affect the operating conditions of the key study intersections and key roadway segments. Table 6-2 presents the trip generation for the thirty-five (35) cumulative projects. As shown in Table 6-2, the thirty-five (35) cumulative projects are forecast to generate a total of 22,368 daily trips, with 1,154 trips (463 inbound and 691 outbound) forecast during the AM peak hour and 1,479 trips (824 inbound and 655 outbound) forecast during the PM peak hour. It should be noted that distribution patterns for each of the cumulative projects were developed based on the location of the trip attractors, type of land use, the site's proximity to major traffic carriers and previously completed traffic studies. It should also be noted that the analysis does not assume any roadway network improvements/mitigation measures associated with any of the thirty-five (35) cumulative projects. The AM and PM peak hour traffic volumes associated with the thirty-five (35) cumulative projects are presented in Figures 6-2 and 6-3, respectively. Figures 6-4 and 6-5 present the existing plus cumulative projects AM and PM peak hour traffic volumes at the two (2) key study intersections.

The previously discussed capacity analysis procedures were utilized to investigate the future volume-to-capacity relationships and service level characteristics at each study intersection and roadway segment. The significance of the potential impacts of the Project at each key intersection and key roadway segment was then evaluated using the following traffic impact criteria. 7.1 Impact Criteria and Thresholds Impacts to local and regional transportation systems located in the City of Anaheim are considered to cause an operational deficiency if: Intersections: According to the City’s Circulation Element and stated in the City of Anaheim Criteria for Preparation of Traffic Impact Studies, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all City intersections. The significance of the potential impacts of the project at each key signalized intersection is determined based on the sliding scale criteria presented in Table 7-1. As indicated in Table 7-1, the project-related increase in ICU value that defines an operational deficiency at signalized intersections varies with LOS. Per the City’s guidelines, a change in ICU value, within LOS C, equal to or greater than 0.050 is an impact and within LOS D, a change in ICU equal to or greater than 0.030 is also an impact. With LOS E or F, a change in ICU equal to or greater than 0.010 is considered an impact. For unsignalized intersections, based on discussions with City of Anaheim Traffic Engineering Department staff, this report defines an operational deficiency if the project causes an intersection operating at LOS D or better to degrade to LOS E or LOS F, and the traffic signal warrant analysis determines that a traffic signal is justified.

Table 10-1 summarizes the intersection operations at the proposed Project access for Year 2022 plus Project traffic. The operations analysis for the project access is based on the Highway Capacity Manual 6th Edition (HCM 6) unsignalized methodology. Review of Table 10-1 shows that the proposed Project access is forecast to operate at LOS C or better during the AM and PM peak hours under Year 2022 Cumulative Plus Project traffic conditions. As such, Project access will be adequate. Motorists entering and exiting the Project site will be able to do so without undue congestion. 10.2 Sight Distance Evaluation At intersections and/or project driveways/private streets, a substantially clear line of sight should be maintained between the driver of a vehicle waiting at the crossroad and the driver of an approaching vehicle. Adequate time must be provided for the waiting vehicle to either cross all lanes of through traffic, cross the near lanes and turn left, or turn right, without requiring through traffic to radically alter their speed. A sight distance evaluation has been performed for the unsignalized Project Access No. 1 located along Western Avenue. The Sight Distance Evaluation prepared for Project Access No. 1 is based on the criteria and procedures set forth by the California Department of Transportation (Caltrans) in the State’s Highway Design Manual (HDM). Stopping sight distance was utilized for the evaluation. Stopping sight distance is defined in the Caltrans HDM to be the distance required by the driver of a vehicle, traveling at a given speed, to maneuver their vehicle and avoid an object without radically altering their speed. Line of sight for stopping sight distance is to be determined from a 3½ foot height at the location of the driver of a vehicle on a minor road to a 4¼ foot object height in the center of the approaching lane of the major road. Based on the criteria set forth in Table 201.1 - Sight Distance Standards of the Caltrans HDM and a posted speed limit of 40 mph along Western Avenue, a stopping sight distance of 440 feet is required for Project Access No. 1. Figure 10-1 presents a schematic of the sight distance evaluation performed at Project Access No. 1 which illustrates the actual sight distance and corresponding limited use area along Western Avenue. A review of Figure 10-1 indicates that the sight lines at this intersection are expected to be adequate provided obstructions within the sight triangles are minimized. In addition, any future landscaping and/or hardscapes (i.e. monument signs) should be designed such that a driver’s clear line of sight is not obstructed.

These capacity improvements involve roadway widening and/or re-striping to reconfigure (add lanes) roadways to specific approaches of a key intersection. The identified improvements are expected to: ▪ Address the impact of existing traffic, Project traffic and future non-project (ambient traffic growth and cumulative) traffic, and ▪ Improve Levels of Service to an acceptable range and/or to pre-project conditions. 11.1 Existing Plus Cumulative Plus Project Recommended Improvements The results of the intersection capacity analysis presented previously in Table 8-1 shows that the proposed Project will not cause an operational deficiency at either of the two (2) key study intersections under the “Existing Plus Cumulative Plus Project” traffic scenario. Given that there are no Project impacts, no improvements are required under this traffic scenario. 11.2 Year 2022 Plus Project Recommended Improvements The results of the intersection capacity analysis presented previously in Table 9-1 shows that the proposed Project will not cause an operational deficiency at either of the two (2) key study intersections under the “Year 2022 Plus Project” traffic scenario. Given that there are no Project impacts, no improvements are required under this traffic scenario.

Traffic Study Scope of Work The Traffic Impact Analysis for the proposed Pepperwood Place Project will satisfy the traffic impact requirements of the City of Anaheim Criteria for Preparation of Traffic Impact Studies and the City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis (June 2020), and will be consistent with the requirements and procedures outlined in the most current Congestion Management Program (CMP) for Orange County. A. Project Location: The proposed Project site is located at 910 S. Western Avenue (i.e. generally on the east side of Western Avenue and north of Ball Road), in the City of Anaheim, California. The Project site is currently occupied with a vacant single-family home that will be demolished. See the attached Vicinity Map – Figure 1 and Existing Aerial Site Plan – Figure 2. B. Project Description: The proposed Project will consist of 12 single-family residential dwelling units on a private street with a “hammerhead” turnaround area. Access will be provided via one (1) full access private street driveway along Western Avenue (i.e. Project Driveway No. 1). For the traffic analysis, a Year 2022 project horizon year will be utilized. See the attached Proposed Site Plan – Figure 3. C. Project Study Area: The following three (3) key study intersections have been selected for evaluation based on discussions with City of Anaheim Public Works Department staff. Key Study Intersections 1) Western Avenue at Orange Avenue 2) Western Avenue at Ball Road 3) Western Avenue at Project Driveway A-1 Mr. David Kennedy January 20, 2021 Page 2 D.Traffic Counts: Due to the State of California “Stay at Home” order as a result of the COVID-19 Coronavirus Pandemic, historical weekday AM peak hour and PM peak hour traffic counts has been researched for the two (2) key study intersections. Specifically, the historical traffic counts for the two (2) key study intersections were conducted by Counts Unlimited on December 10, 2019 and will be factored up by the City-approved growth factor of 1.0% per year to reflect current Year 2021 existing baseline traffic conditions (i.e. 2% total growth). E.Project Traffic Generation: The trip generation potential of the proposed Project will be estimated using ITE Land Use 210: Single-Family Detached Housing trip rates contained in the 10th Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE), [Washington, D.C., 2017]. Table 1 summarizes the trip generation rates used in forecasting the vehicular trips generated by the proposed Project and presents the forecast daily and peak hour project traffic volumes for a “typical” weekday. Review of the lower portion of Table 1 indicates that the proposed Project is forecast to generate approximately 113 daily trips, with 9 trips (2 inbound, 7 outbound) produced in the AM peak hour and 12 trips (8 inbound, 4 outbound) produced in the PM peak hour. F.Project Trip Distribution Pattern: See the attached Project Trip Distribution Pattern – Figure 4. G.Year 2022 Cumulative Traffic: ▪Ambient Growth Rate: 1.0% per year. ▪Cumulative Projects – Obtain information regarding cumulative projects in the vicinity of the proposed project (i.e. 2-mile radius) from the City of Anaheim, the City of Cypress, the City of Buena Park, the City of Stanton, and the City of Garden Grove. H.Analysis Scenarios: The following traffic analysis scenarios will be prepared for the proposed Project. (a)Existing Traffic Conditions; (b)Existing Plus Cumulative Traffic Conditions; (c)Existing Plus Cumulative Plus Project Traffic Conditions; (d)Year 2022 Cumulative Traffic Conditions; (e)Year 2022 Cumulative Plus Project Traffic Conditions; The LOS calculations for the key study intersections will be based on the ICU methodology for signalized intersections and the Highway Capacity Manual (HCM) methodology for unsignalized intersections.

Date: September 2, 2021 From: Keil D. Maberry, P.E., Principal Linscott, Law and Greenspan, Engineers LLG Ref: 2.21.4355.1 Subject: Final Vehicle Miles Traveled (VMT) Assessment for the Proposed Pepperwood Place Project, Anaheim As requested, Linscott, Law & Greenspan, Engineers (LLG) is pleased to submit this Final Vehicle Miles Traveled (VMT) Assessment Technical Memorandum for the proposed Pepperwood Place project (herein after referred to as Project) in Anaheim, California. This Technical Memorandum presents the VMT screening criteria and applies the criteria, accordingly. It should be noted that the approach and methodology outlined in this Technical Memorandum is based on the City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis (June 2020) and is generally consistent with the Technical Advisory for Evaluating Transportation Impacts In CEQA, published by the Governor’s Office of Planning and Research (OPR), December 2018 (OPR Technical Advisory), which provides additional detail on the language and approach described in this Technical Memorandum. On December 28, 2018, the California Natural Resources Agency adopted revised CEQA Guidelines. Among the changes to the guidelines was the removal of vehicle delay and LOS from consideration for transportation impacts under CEQA. With the adopted guidelines, transportation impacts are to be evaluated based on a project’s effect on vehicle miles traveled. Lead agencies are allowed to continue using their current impact criteria, or to opt into the revised transportation guidelines. However, the new guidelines must be used starting July 1, 2020, as required in CEQA section 15064.3. The City of Anaheim has adopted thresholds as contained in the City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis (June 2020). In late 2019, State courts stated that under section 21099, subdivision (b)(2), existing law is that “automobile delay, as described solely by level of service or similar measures of vehicular capacity or traffic congestion shall not be considered a significant impact on the environment” under CEQA, except for roadway capacity projects. As a result of SB 743, the new metric in the CEQA guidelines for transportation impacts is VMT per capita. The legislative intent of SB 743 is to balance the needs of congestion management with statewide goals for infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions. Ms. Mallory McGaughy September 2, 2021 Page 2 N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place VMT Assessment - Anaheim, 09-02-21.docx PROJECT DESCRIPTION The proposed Project will consist of 12 single-family residential dwelling units on a private street with a “hammerhead” turnaround area and is expected to be completed in the Year 2022. The proposed Project is consistent with the existing land use and City of Anaheim General Plan. The proposed project site is located at 910 S. Western Avenue (i.e. generally on the east side of Western Avenue and north of Ball Road), in the City of Anaheim, California. The Project site is currently occupied with a vacant single-family home that will be demolished. Therefore, the proposed Project consists of a net eleven (11) new homes. PROJECT SCREENING CRITERIA Under the VMT methodology, screening is used to determine if a project will be required to conduct a detailed VMT analysis. There are several types of screening that the lead agencies can apply to effectively screen projects from project-level assessment. As such, the following guidance summarizes the potential project screening, developed for the City of Anaheim: Type 1: Transit Priority Area (TPA) Screening As noted previously, the CEQA Guidelines were amended to include section 15064.3, “Determining the Significance of Transportation Impacts”. Subsection (b)(1) states in part: “Generally, projects within one-half mile of either an existing major transit stop or a stop along an existing high quality transit corridor should be presumed to cause a less than significant transportation impact.” Pursuant to the statute, development projects may be screened out of VMT analysis based on proximity to certain transit facilities due to the presumption of less than significant impacts. The Technical Advisory reiterates this screening criteria, but also highlights certain project-specific or location-specific characteristics which may indicate the project will still generate “significant levels of VMT”, even when located within one-half mile of a major transit stop or a stop along a high-quality transit corridor. These characteristics relate to the project’s floor area ratio (FAR), parking supply, and number of dwelling units, as well as consistency with the applicable Sustainable Communities Strategy (SCS). If the project has any characteristics which indicate that the presumption of less than significant impacts as stated in the CEQA Guidelines may not be appropriate, the OPR Technical Advisory recommends that the project should not be screened out of further VMT analysis. Ms. Mallory McGaughy September 2, 2021 Page 3 N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place VMT Assessment - Anaheim, 09-02-21.docx The City of Anaheim has a developed a TPA map, which was utilized to determine whether this Project can be screened out based on the TPA criteria. 1. Has a total Floor Area Ratio (FAR) of less than 0.75; 2. Includes more parking for use by residents, customers, or employees of the project than required by the jurisdiction (if the jurisdiction requires the project to supply parking); 3. Is inconsistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Metropolitan Planning Organization); or 4. Replaces affordable residential units with a smaller number of moderate‐ or high‐income residential units. Based on the above, the proposed Project will not screen-out under this criteria since while the Project site is within the TPA defined by Attachment A, attached, of the City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis (June 2020), the Project Floor Area Ratio is less than 0.75. Type 2: Low VMT Area Screening An additional screening methodology is provided for residential and office land use projects. Lead agencies may prepare maps based on a regional travel demand model or travel survey data to illustrate areas that are currently below the selected VMT threshold. OPR reasons that if a project has similar characteristics to the existing area (i.e., density, mix of uses, transit service, etc.), it will tend to exhibit similar VMT. Therefore, if a project is fully located within an area identified as having a below- threshold VMT, it may be presumed to also have less than significant VMT impacts and be screened out from requiring a detailed VMT analysis. The City of Anaheim has a developed a map showing low VMT-generating zones as compared to the County, which was utilized to determine whether this Project can be screened out based on the low VMT-generating area criteria. In addition, the Project must be consistent with the existing land use within that TAZ. Therefore, a review was conducted to confirm that the Project land use is consistent with the existing land use within the Orange County Transportation Analysis Model (OCTAM). The proposed Project is located in the OCTAM traffic analysis zone (TAZ) 350. Table 1, below, summarizes the TAZ 350 existing land uses. Ms. Mallory McGaughy September 2, 2021 Page 4 N:\4300\2204355 - Pepperwood Place, Anaheim\Report\4355 - Pepperwood Place VMT Assessment - Anaheim, 09-02-21.docx TABLE 1 TAZ 350 Existing Land Use Summary[1] Based on the above, the proposed Project will screen-out under this criteria since the Project site is located within a low VMT-generating area (<15% below the Orange County Average) defined by Attachment B, attached, of the City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis (June 2020) and the Project is consistent with the existing land use in the TAZ, which is primarily residential. CONCLUSION Consistent with the OPR Technical Advisory and City of Anaheim Guidelines the proposed Pepperwood Place Project will result in a less-than-significant transportation impact based on the City of Anaheim Type 2: Low VMT Area Screening. * * * * * * * * * * * We appreciate the opportunity to provide this Technical Memorandum.

PROJECT LOCATION The project site is A-Town, Tract 17703, Lot 1 – Area B, in the City of Anaheim (City), County of Orange. The site is bounded by Katella Avenue on the north, Westside Drive on the west, Meridian Street on the south, and Market Street on the east (see attached Vicinity Map for more information). B. STUDY PURPOSE This study is to accompany the submittal of a Water Quality report. This study is preliminary, determines the 100-year, 25-year, 10-year, and 2-year peak storm runoff produced from the project site as approved by the City in 2016 for the overall Tract 17703 . C. METHODOLOGY The methodology used to determine the peak discharges for A-Town is based upon the criteria set forth in the Orange County Flood Control District Hydrology Manual dated 1986 as incorporated in the Advanced Engineering Software (AES) “RATSC” Program. The hydrologic soil types were determined from the Hydrologic Classification of Soils map contained in the Orange County Hydrology Manual. D. DISCUSSION Per the current Site Plan, storm runoff produced from Lot 1 - Area B will drain in the same pattern and at the rate as shown on the proposed hydrology map of the approved drainage report dated April 27, 2016. First flush flows produced from the site are collected in the proposed inlets throughout the site, then being diverted in the proposed diversion structures to drain to proposed Modular Wetland Systems. Water quality structures are shown on the hydrology map with dimensions and are addressed in details in a separate WQMP report.

No.: 11109179 From: Ulysses Fandino, GHD Tel: 949-585-5203 CC: Keith Linker, City of Anaheim Subject: 910 S. Western Avenue Development Sewer Analysis 1. Background The City of Anaheim (City) has retained GHD to perform a sewer analysis on the City’s sewer collection system to determine the effects of a proposed residential development located at 910 S. Western Avenue (Development) within the West Anaheim Master Plan of Sanitary Sewer (WAMPSS) study area. The Development consists of redeveloping a single family residential parcel and a vacant parcel into 12 single family homes. The developer intends to connect to an existing 10-inch sewer main along Western Avenue that is currently identified as hydraulically deficient in the WAMPSS report. However, the City has recently identified an OCSD outfall connection at the intersection of Orange Avenue and Western Avenue that has an effect on the flow hydraulics of the sewer reaches downstream of the Development. This hydraulic analysis will determine if the existing 10-inch to 12-inch sewer main downstream of the proposed connection point will be able to accommodate the additional sewer flows from the Development after the newfound OCSD connection is factored in. 2. Methodology The sewer hydraulic analysis utilized the current iteration of the sewer hydraulic model prepared for the 2015 WAMPSS update. The WAMPSS sewer model includes all sewer improvements the City has constructed since the previous 2005 Combined West Anaheim Area Master Plan of Sanitary Sewers and the sewer configuration revisions included in the WAMPSS Additional Modeling, Sewer Analysis, and Results at Western Avenue technical memorandum dated January 12, 2021. Sewer loadings to the model have been calibrated to flow monitoring data to reflect the current sewer flow conditions. Sewer pipe alignments, elevations, connections, and manholes for the project area were verified during the WAMPSS update. The anticipated sewer generation changes are inputted into the hydraulic model for analysis. The following sections describe the study area for this sewer analysis, the proposed land use change, the methodology for preparing the sewer hydraulic model, and the revised sewer loadings from the proposed development. 910 S. Western Avenue Development Sewer Analysis 2 2.1 Study Area The Development consists of redeveloping two parcels on the east side of Western Avenue between Teranimar Drive and Ball Road (APNs 07988237 and 07988236). APN 07988237 is currently occupied by a single family home, while APN 07988236 is currently vacant. The two lots have a combined area of approximately 1.4 acres and will be redeveloped into 12 single family homes. The lots are assigned the “RM-1 Corridor Residential” designation under the City’s General Plan. The developer proposes to alter the land uses to “RS-4 Single Family Residential”. According to the site plan provided by the developer (see Attachment), the Development will have one connection to the City’s sewer collection system, located between Manhole SW006435 and Manhole SW006434 on a southerly-flowing 10-inch sewer main along the centerline of Western Avenue. The 10-inch main upsizes to a 12-inch sewer main at Manhole SW006427 at Ball Road. The sewer main continues south to the southern city limits and outfalls to the City of Stanton sewer collection system. An 8-inch sewer main runs parallel to the 10-inch main on the east side of Western Avenue. The 8-inch main joins the westerly-flowing 18-inch sewer main in Ball Road and outfalls to an OCSD trunk sewer in Knott Avenue. The Study Area is presented in Figure 2.1.

Western Avenue Development o 910 S. Western Avenue Development Sewer Analysis 4 2.2 Sewer Model Methodology The sewer hydraulic model prepared for the WAMPSS and recently updated per the additional analysis performed in January 2021 were used as a basis for this sewer study. The model was developed using the Innovyze H2OMAP Sewer hydraulic modeling software. Average sewage flows were calculated based on the land use and census data provided by the City, and unit flow factors were developed for the WAMPSS according to flow monitoring data and past sewer master plan studies. These flows were then allocated to the nearest manholes within the model. Peak flows were determined by applying diurnal curves according to land uses, as described in the next section. The ratio of flow depth to pipe diameter at the actual peak flow is designated d/D. This d/D was calculated by the modeling program and was used to identify pipes needing improvement. The City’s analysis criteria call for a maximum allowable d/D = 0.67 for pipes with diameters less than 12 inches, and d/D = 0.75 for pipes with diameters equal to or greater than 12 inches. Thus, pipes with d/D ratios equal to or greater than these values were identified as needing improvement. The City also have separate criteria for new sewer design that are more stringent than the analysis criteria specified above. These criteria call for a maximum allowable d/D = 0.50 for pipes with diameters less than 12 inches, and a d/D = 0.60 for pipes with diameters equal to or greater than 12 inches. 2.3 Peak Flow Methodology The methodology for peak sewer flow modeling within the study area is based on diurnal curves, which uses a 24-hour flow generation curve to represent the pattern of sewage flows generated by type of land use. The residential and non-residential diurnal curves from the WAMPSS update were applied to the model. The diurnal curves are shown in Figure 2.2 and Figure 2.3. The x-axis represents a 24-hour period starting and ending at midnight, while the y-axis represents the peaking factor applied to the normal flow factor at each hour of the day. 910 S. Western Avenue Development Sewer Analysis 5 Figure 2.2 Residential Diurnal Curve Figure 2.3 Non-Residential Diurnal Curve 2.4 Sewer Loadings for Study Area The proposed land uses, along with the calibrated and adjusted unit flow factors from the WAMPSS update, determined the sewage flows to be generated from the Development. The sewer loadings for the two subject parcels are currently loaded to Manhole SW006429, which is located on the existing 8-inch sewer 910 S. Western Avenue Development Sewer Analysis 6 main on the east side of Western Avenue closest to the parcels. However, as mentioned previously, the developer intends to connect to the existing 10-inch sewer main on the west side of Western Avenue instead. For the purpose of this analysis, the sewer loadings from the proposed residences are loaded to the nearest existing manhole on the existing 10-inch sewer main instead, which is Manhole SW006434. The estimated sewer loading is listed in Table 2.1 below. Table 2.1 Estimated Sewer Loading for 910 S. Western Avenue Development Land Use Type Dwelling Unit Count Sewer Unit Flow Factor Sewer Loading Proposed Loading Manhole Single Family Residential 12 DU 300 gpd/DU 3,600 gpd SW006434 DU = Dwelling unit gpd = gallons per day 3. Hydraulic Model Analysis To determine the effects of altering land uses within the study area as proposed by the developer, two (2) model scenarios were analyzed: • WAMPSS Existing Condition plus the Development • WAMPSS Build-Out Condition plus the Development For simplicity, the model results focus on the pipes downstream of the Development’s proposed sewer connection point only. The model results are reported by Pipe ID, which is comprised of each pipe’s upstream and downstream manhole identification number. 3.1 Scenario 1 – WAMPSS Existing Condition plus the Development The first scenario builds on the WAMPSS Existing Condition model scenario, but assumes the Development is fully built and occupied. The flow for the existing single family home was removed from the scenario and replaced with the flows for the proposed residential units as presented in Section 2.4. The steady state loading from the Development in this scenario is 3,600 gallons per day (gpd), an increase of 3,300 gpd over the WAMPSS Existing Condition loading. Analysis of this scenario revealed no deficiencies in the pipelines downstream of the proposed development. The peak flows in these pipelines were within the allowable d/D ratios, with a maximum d/D ratio of 0.45 observed in Pipe SW006434-SW006433. Flow velocities are relatively low in the sewer reaches downstream of the Development since most segments are flat with pipe slopes as low as 0.0015. Maximum velocities in these sewer reaches range from 1.6 to 2.4 feet per second (ft/s). The hydraulic model results are presented in Table 3.1 from upstream to downstream and in Figure 3.1.

Western Avenue Development o 910 S. Western Avenue Development Sewer Analysis 9 3.2 Scenario 2 – WAMPSS Build-Out Condition plus the Development Scenario 2 expands on the WAMPSS Build-Out model scenario with the inclusion of the loadings from the Development. For the purpose of the model and based on an evaluation of the historical water usage trends, the WAMPSS established the Existing and Build-Out flow factors to be the same. The proposed per capita sewer generation factor is conservative compared to the Existing Condition sewer flows that were confirmed by sewer flow monitoring data. It is expected that the ongoing water conservation efforts such as the installation of low flow water fixtures will keep the per capita generation factor relatively stable. The average household densities are also expected to remain stable based on historical census trends. Even though the flow factors are the same between the Existing Condition and Build-Out Condition scenarios, the Build-Out Condition flow is equal to or higher than the Existing Condition flow since the maximum building density from the General Plan was applied when determining the flow from each parcel, except for the subject parcel of this analysis. The main purpose of Scenario 2 is to identify any potential deficiencies in the downstream sewer reaches due to the increased Build -Out Condition flows from the rest of the tributary area. The sewer loadings from the Development are identical for Scenario 1 and Scenario 2 since it is assumed the proposed residences will remain in occupancy under the Build-Out Condition based on typical building life spans. The steady state loading from the Development in this scenario remains at 3,600 gpd, which represents a decrease of 1,500 gpd over the WAMPSS Build-Out loading since the number of dwelling units proposed for this Development is lower than the number of units estimated for the WAMPSS Build-Out model scenario. Analysis of this scenario also revealed no deficiencies in the pipelines downstream of the proposed development. The peak flows in these pipelines were within the allowable d/D ratios, with a maximum d/D ratio of 0.49 observed in Pipe SW006434-SW006433. Similar to Scenario 1, maximum flow velocities are relatively low due to the shallow slope of the existing sewer. The hydraulic model results are presented in Table 3.2 from upstream to downstream and in Figure 3.2.

Western Avenue Development o 910 S. Western Avenue Development Sewer Analysis 12 4. Conclusion The 910 S. Western Avenue development is a proposed residential development on the east side of Western Avenue between Teranimar Drive and Ball Road. The project consists of redeveloping two parcels, approximately 1.4 acres in area, into 12 single family residences. The Development is projected to contribute a steady state sewage flow of 3,600 gpd, which represents a 3,300 gpd increase over the sewer loading WAMPSS Existing Condition loading and a 1,500 gpd decrease when compared to the WAMPSS Build-Out Condition loading. The sewer analysis revealed no hydraulic deficiencies in the pipelines downstream of the Development in the Existing Condition and Build-Out Condition model scenarios. Maximum d/D ratios of up to 0.49 were observed downstream of the Development’s sewer connection point, which are within the City’s maximum allowable d/D of 0.67 for pipes with diameters less than 12 inches and 0.75 for pipes with diameters equal to or greater than 12 inches.

Project Area (ft2): 60,548 Number of Dwelling Units: 12 SIC Code: ____N/A______ Project Area Pervious Impervious Area (acres or sq ft) Percentage Area (acres or sq ft) Percentage Pre-Project Conditions 1.2 86% 0.19 14% Post-Project Conditions .45 33% .94 67% Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 8 Drainage Patterns/Connections The project is located within the Coyote Creek Watershed. In the existing condition runoff originating within the Site drains southwest towards Western Avenue unmitigated and then conveyed to an existing drop inlet off of the intersection of Ball Road and Western Avenue. There is no existing storm drain system onsite, and there is no run-on from the existing slope to the project site. In the proposed condition the Site is divided into two (2) DMAs (see BMP location map).The stomwater treatment facility that is proposed for each DMA is infiltration, via permeable pavement. Due to seasonally high water table, underground storage via pipe or chambers was deemed unapplicable. The DCV will be treated by passing through the stone layer of the permeable pavers and allowing the runoff to infiltrate while reducing the peak runoff velocity and volume. DMA A is .70 AC, which is located in the North side of the project and will drain to the northern portion of the permeable pavers. This permeable pavers will treat the run off from roofs, pads and portion of street A and ultimately infiltrate to the ground. DMA B is .69 AC, which is located in the South side of the project and will drain to the southern portion of the permeable pavers. This permeable pavers will treat the run off from roofs, pads and portion of street A and ultimately infiltrate to the ground. Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 9 Narrative Project Description: (Use as much space as necessary.) The 1.39- acre project site is located in the City of Anaheim, just northeast of the Ball Road and and Western Avenue intersection. The site is a re-development of a former residential area and will be turned into a more elaborate residential area of residential properties. Each house is around 1,800 sq ft with 2-3 bedrooms per home creating twelve large building lots on the site. The project site is bound by residential area in the north, south, east and west direction. Tract No. 17944 is a residential development that includes the construction of multifamily housing, private streets, and common area landscaping and associated wet and dry utilities. Landscape surrounds all paved areas and building on the site. All houses sheet flow unto the streets curb and gutter and ultimately drain to one of two modular wetlands. Storm water runoff will be collected and conveyed through permeable pavers. Right of way improvements will also be done and will be treated via a curb cut in connection with a planter tree. Right of way improvements consist of modified curb and gutter, redesign of the existing sidewalk, and construction of new corner curb ramps to meet the city of Anaheim’s standards. Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 10 II.2 Potential Stormwater Pollutants Determine and list expected stormwater pollutants based on land uses and site activities.

Refer to Section 2.2.3.2 in the Technical Guidance Document (TGD) and Appendix G of the Model WQMP for reference to applicable technical guidance for determining if downstream channels are susceptible to HCOCs. No – Determination is described below Yes – Describe applicable hydrologic conditions of concern below. Refer to Section 2.2.3 in the Technical Guidance Document (TGD). II.4 Post Development Drainage Characteristics Describe post development drainage characteristics. Refer to Section 2.2.4 in the Technical Guidance Document (TGD). In the proposed condition the Site is divided into two (2) DMAs (see BMP location map).The stomwater treatment facility that is proposed for each DMA is a permeable pavers. The permeable pavers contain stone for physically and chemically capturing pollutants from DCV. The DCV will be treated through the porosity of the stones in the reservoir portion of the pavers and ultimately infiltrate into the ground. The treated stormwater will infiltrate into the ground and only in heavy stormwater condition s, will the stormwater overflow from the sump condition onto Western Avenue. DMA A is .70 AC, which is located in the North side of the project and drain to the private street and ultimately onto the permeable pavers. The permeable pavers will treat the run off from roofs, pads and portion of street A and ultimately infiltrate to the ground. DMA B is .69 AC, which is located in the South side of the project and drain to the private street and ultimately onto the permeable pavers. The permeable pavers will treat the run off from roofs, pads and portion of street A and ultimately infiltrate to the ground. During a low flow event, stormwater will travel to the permeable pavers where water will infiltrate into the ground. During a high flow event water will travel to permeable pavers like during the low flow event. The reservoir portion of the permeable pavers have enough volume to hold the Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 12 net 100-year flow from the existing site to the proposed site. The permeable paver will hold 3,300 cf of volume within the 4’ depth of bedding course and subbase. Once the permeable paver are to capacity in the sump condition, water will overflow the grading ridgeline and spill over onto Western Avenue matching existing site conditions. .

Include references to applicable studies/reports related to investigation of the site and evaluation of feasibility of LID BMPs. Site Characteristics Precipitation Zone Resides within the 0.85-inch rainfall zone Topography The development is located in the City of Anaheim. Slopes within the property are relatively flat, ranging from 0.5% to 2% Drainage Patterns/Connections The project is located in the Coyote Creek Watershed. In the existing condition, runoff originating within the Site drains to Western Avenue and then conveyed to an existing 30” pipe in Western Avenue. The site receives no run-on in the existing or proposed conditions. In the proposed condition the Site is divided into two (2) DMAs (see BMP location map).The stomwater treatment facility that is proposed for each DMA is permeable pavers for infiltration purposes. The treated stormwater will infiltrate into the ground and only in heavy stormwater conditions, the stormwater will overflow the grading ridgeline and spill over onto Western Avenue matching existing site conditions. Soil Type, Geology, and Infiltration Properties The site has been previously graded. Limited infiltration can be attributed to the predominant soil type B Hydrogeologic (Groundwater) Conditions Appendix 6 NRCS map shows that project is within soil type B which is an indicator of good infiltration rate. Ground water is encountered 15 feet below ground surface during the geotech report referenced in appendix 6. Geotracker California was used to indicate existing soils information along with geotech reports in appendix 6. Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 16 Geotechnical Conditions (relevant to infiltration) Research of the California Geological Survey (CGC) seismic hazard zones map shows that the subject site is not located within a zone of potential seismically include slope instability. Appendix 6 includes a preliminary report for Infiltration BMP Feasibility that concluded infiltration at the site is feasible due to having an infiltration rate of 0.98 inches/hr. Since 0.98 inches/hr is above the minimum rate needed for infiltration, water will be treated via a modular wetland and ultimately infiltrate to the ground via the connecting perforated 48” hdpe. Lastly no contamination is within 250’ of the project site per the geotracker information. Please see Geotechnical Report in Appendix 6 Off-Site Drainage The site does not receive run-on. Utility and Infrastructure Information All proposed utilities within the project will be owned and maintained by Pepperwood Place LP. Upon completion of the project, a Home Owners’ Association (HOA) will be formed for responsibility of utilities for the project. The proposed storm drain system and piping network within the project are private system. The City of Anaheim assumes no liability or responsibility for the storm drain system, the storm water conveyed within it, or maintenance of the storm drain system. Upon completion of the project, Pepperwood Place LP will be responsible for the transfer of ownership and responsibilities. The HOA is required to maintain all storm drains and remove accumulated sediments to ensure adequate drainage.

Refer to Section 7.II-3.2.2 of the SOC Model WQMP for description of credits and Appendix VI of the Technical Guidance Document (TGD) for calculation methods for applying water quality credits. Description of Proposed Project Project Types that Qualify for Water Quality Credits (Select all that apply): Redevelopment projects that reduce the overall impervious footprint of the project site. Brownfield redevelopment, meaning redevelopment, expansion, or reuse of real property which may be complicated by the presence or potential presence of hazardous substances, pollutants or contaminants, and which have the potential to contribute to adverse ground or surface WQ if not redeveloped. Higher density development projects which include two distinct categories (credits can only be taken for one category): those with more than seven units per acre of development (lower credit allowance); vertical density developments, for example, those with a Floor to Area Ratio (FAR) of 2 or those having more than 18 units per acre (greater credit allowance). Mixed use development, such as a combination of residential, commercial, industrial, office, institutional, or other land uses which incorporate design principles that can demonstrate environmental benefits that would not be realized through single use projects (e.g. reduced vehicle trip traffic with the potential to reduce sources of water or air pollution). Transit-oriented developments, such as a mixed use residential or commercial area designed to maximize access to public transportation; similar to above criterion, but where the development center is within one half mile of a mass transit center (e.g. bus, rail, light rail or commuter train station). Such projects would not be able to take credit for both categories, but may have greater credit assigned Redevelopment projects in an established historic district, historic preservation area, or similar significant city area including core City Center areas (to be defined through mapping). Water Quality Management Plan (WQMP) Tract 17944 August 26th, 2021 Page 34 Developments with dedication of undeveloped portions to parks, preservation areas and other pervious uses. Development s in a city center area. Developme nts in historic districts or historic preservatio n areas. Live-work developments, a variety of developments designed to support residential and vocational needs together – similar to criteria to mixed use development; would not be able to take credit for both categories.

(See Appendix XVII) Provide narrative discussion and supporting evidence: Summarize findings of studies provide reference to studies, calculations, maps, data sources, etc. Provide narrative discussion of study/data source applicability. 9 If any answer from row 1-3 is yes: infiltration of any volume is not feasible within the DMA or equivalent. Provide basis: Summarize findings of infeasibility screening 10 If any answer from row 4-7 is yes, infiltration is permissible but is not presumed to be feasible for the entire DCV. Criteria for designing biotreatment BMPs to achieve the maximum feasible infiltration and ET shall apply. Provide basis: Summarize findings of infeasibility screening 11 If all answers to rows 1 through 11 are no, infiltration of the full DCV is potentially feasible, BMPs must be designed to infiltrate the full DCV to the maximum extent practicable. Harvest and Use Infeasibility Harvest and use infeasibility criteria include:  If inadequate demand exists for the use of the harvested rainwater. See Appendix X for guidance on determining harvested water demand and applicable feasibility thresholds.  If the use of harvested water for the type of demand on the project violates codes or ordinances most applicable to stormwater harvesting in effect at the time of project application and a waiver of these codes and/or ordinances cannot be obtained. It is noted that codes and ordinances most applicable to stormwater harvesting may change Volume Based Treatment Calculations DMA-A (treat the run off from North side of the project and portion of street A) DCV = (C x (D)reminder x A x 43560 x (1/12) Area=0.70 acres Impervious are of DMA #1= .45 acres (66%) Design Capture storm depth = 0.85 in. Runoff Coefficient: C=(.75)(.66)+.15=.65 DCV = (0.65) (0.85 in) (0.70 ac) (43560 sf) (1/12) DCV = 1,403 cf Permeable paver will treat 3200 cu-ft of volume which is greater than 1,403 hence adequately sized. DMA-B (treat the run off from South side of the project and portion of street A) DCV = (C x (D)reminder x A x 43560 x (1/12) Area=0.69 acres Impervious are of DMA #2= .45 acres (67%) Design Capture storm depth = 0.85 in. Runoff Coefficient: C=(.75)(.67)+.15=.65 DCV = (0.65) (0.85 in) (0.69 ac) (43560 sf) (1/12) DCV = 1,384 cf Permeable paver will treat 3200 cu-ft of volume which is greater than 1,384 hence adequately sized. Permeable Pavement Section Detail With Drawdown Explanation Permeable pavers exhibit extremely high infiltration rate (785 to 2544 in/hr) which are orders of magnitude higher than any design storm including the 100 year storm. Since the slope of the permeable pavers is relatively flat (less then 1% slope) the area provided will intercept the 100 year flow rate and not by pass the pervious area, until reservoir portion is to capacity. Permeable Pavement Drawdown Explanation Per the infiltration report in Section 6, the site’s infiltration rate is 0.98”/hr with a factor of safety of 2. Total depth of the permeable pavement is 48”. Drawdown time = total depth / infiltration rate Drawdown time = 48” / 0.98” an hour Drawdown time = 49 hours 49 hours of drawdown time is sufficient to meet wqmp standards hence ok. Volume Based Treatment Calculations (Off-site) DMA-Offsite DCV = (C x (D)reminder x A x 43560 x (1/12) Area=0.08 acres Impervious area of DMA #1= .063 acres (79%) Design Capture storm depth = 0.85 in. Runoff Coefficient: C=(.75)(.79)+.15=.74 DCV = (0.74) (0.85 in) (0.08 ac) (43560 sf) (1/12) DCV = 183 cf Storm-tree will be a ST-4X6 system with 18’x8’x4’ surrounding stone area. Stone area has a porosity rate of 0.4 so total treatment is 18’ x 8’ x 4’ = 576 cf 576 cf x 0.4 porosity = 230 cf of treatment which is greater than 183 cf of treatment. hence adequately sized. Stone layer is below surface and not seen above ground. Storm Tree example.

Chapman Avenue Orange, CA 92666 Subject: Draft Infiltration Results and Recommendations for Proposed Twelve Single Family Homes at 910 S. Western Ave., City of Anaheim, California Dear Ms. McGaughy: We are submitting herewith our draft infiltration results and recommendations for the property located at 910 South Western Avenue in Anaheim, California. SUBSURFACE EXPLORATION Our subsurface exploration was performed on April 10 and April 17, 2019 and involved the following: • Drilling of four (4) 8” hollow stem borings (B-1 through B-4) to depths ranging from 21.5 to 51.5 feet (approximately) below the existing ground surface. • Advancing four (4) CPT soundings (CPT-1, CPT-2, CPT-3, and CPT-4) to depths of approximately 65 feet. • One pilot percolation test was drilled and tested using an 8-inch hollow stem auger (P-1) to observe infiltration characteristics of subsurface materials that will be utilized in design in the infiltration system. Soil materials encountered in the borings were visually classified and logged in accordance with the Unified Soil Classification System. The approximate locations of the CPT soundings and exploratory borings are shown on the attached geotechnical map (Figure 2), and descriptive exploration logs are presented in Appendix A. Associated with the subsurface exploration was the collection of bulk and relatively undisturbed samples of the on-site soil materials for laboratory testing. California modified ring samples were collected from the hand auger borings utilizing hand-driven sampling equipment. Bulk and ring samples were transported to the laboratory for testing. DRAFTPEPPERWOOD PLACE May 30, 2019 910 S. Western Avenue / Anaheim J.N. 17-440 Page 2 FINDINGS Local Geology and Subsurface Conditions As shown on the CPT sounding and boring logs included in Appendix A our subsurface investigation revealed that the subject site is underlain by alluvial deposits that extend to the depth of our investigation (65 feet). These materials consist predominantly of interlayered loose to dense, fine-grained sand, silty sand and clayey sand, and soft to locally firm silt, sandy clay and clay. The moisture content of these native soils varies from slightly moist to saturated with moisture content generally increasing with depth. Laboratory testing of relatively undisturbed samples of alluvial soils yielded in-place dry densities ranging from 81.9 to 112.2 pounds per cubic foot. In all four of the exploratory hollow stem borings within the subject site, the native alluvial materials described above were observed to be overlain by approximately 1- to 2-feet of artificial fill. These fill materials were found to consist of dry to moist, loose, silty sand. Given the age of the existing residence, it is unlikely that the onsite fill materials were placed in accordance with current grading standards. In addition, no documentation has been made available that would indicate that fill placement was observed, tested and certified by a qualified geotechnical consultant. For this reason, all existing onsite fill is classified as "undocumented" for purposes of this investigation. Groundwater At the time of our subsurface investigation on April 10 and April 17, 2019, groundwater was recorded from pore dissipation tests in our CPT soundings at depths ranging from approximately 10.5 to 14.0 feet below the existing ground. Similar groundwater depths ranging from 13 to 15 feet below ground surface were measured during the drilling of hollow stem borings B-1 and B-2. The Department of Conservation’s seismic hazard zone report (1998) puts historic high groundwater for the site at a depth of less than 10 feet. According to a Soil Vapor Investigation Report performed by Dudek on a site located at 3175 West Ball Road, Anaheim, approximately 150 feet south of the subject site, multiple groundwater monitoring wells were installed throughout the site. Groundwater measurements in November 2011 ranged from approximately 6 to 8 feet below ground surface. Previous measurements also took place at that site between 1988 and 2000 and measured groundwater ranged between 5.4 and 17.8 feet bgs. DRAFTPEPPERWOOD PLACE May 30, 2019 910 S. Western Avenue / Anaheim J.N. 17-440 Page 3 PERCOLATION TESTING Percolation testing was conducted in Exploratory Boring P-1 in accordance with County of Riverside Department of Environmental Health (RCDEH) test procedures and the guidelines presented in Appendix VII of the County of Orange Technical Guidance Document for WQMPs. The Orange County Manual references the RCDEH percolation test methods as an acceptable method of obtaining site infiltration data. The “percolation rates” determined in accordance with the RCDEH test procedures are based on both horizontal (lateral) and vertical percolation. Therefore, to consider vertical percolation only, the “percolation rates” were converted to a reasonable estimate of the “infiltration rate” using the Porchet Method presented in Appendix VII of the referenced County of Orange Technical Guidance Document. Boring P-1 was converted to a percolation test hole prior to backfill of the boring. Following the drilling of this boring, a three-inch (I.D.) perforated PVC pipe was placed in the test hole. Open-graded gravel (approximately ¾-inch) was then placed within the annular space between the pipe and boring walls, including a 3-inch thick layer of gravel below the pipe. The gravel was backfilled to approximately 1 foot from the surface, and the remainder of the annular space was backfilled with boring cuttings. Clean water was then added to the boring to pre-soak the adjacent soils prior to performing the percolation test. The percolation test was conducted in a mix of silty sands that exist from the near-surface to below the base of the percolation test. Boring P-1 was drilled to a total depth of approximately 3 feet. The test hole was filled with clean water to approximately 1 foot from the ground surface. The drop in water level was measured at 30-minute intervals. From these readings, the percolation characteristics of the underlying alluvial deposits were estimated. The approximate location of the percolation test is shown on Figure 2 and percolation test results are presented in Appendix C and are summarized below in Table 2.

The term describes a system comprising a load bearing, durable surface together with an underlying structure that temporarily stores water prior to infiltration or drainage to a controlled outlet. The surface can itself be porous such that water infiltrates across the entire surface of the material or can be built up of impermeable blocks separated by spaces and joints, through which the water can drain. Advantages of pervious pavements is that they reduce runoff volume while providing treatment, and are unobtrusive resulting in a high level of acceptability. Vacuum clean surface using commercially available sweeping machines at the end of winter, mid summer and after autumn leaf fall. If routine cleaning does not restore infiltration rates, then reconstruction of part of the whole of a pervious surface may be required. Removal of silts may need to be disposed of at a controlled site. It is recommended that the vacuum service be serviced a minimum of 2 times per year and after each large storm event.

Anaheim Boulevard. 2nd Floor Anaheim, California 92805 www.anaheim.net/publicworks WATER QUALITY MANAGEMENT PLAN PROCEDURES I. GENERAL WATER QUALITY MANAGEMENT PLANS REQUIRED NPDES Water Quality Management Plans are required for private new development and significant redevelopment projects and equivalent City of Anaheim capital projects that qualify as a priority project or a non priority project. The following definitions are taken from the Orange County 2003 Drainage Area Management Plan (DAMP): New Development – means land disturbing activities; structural development, including construction or installation of a building or structure, the creation of impervious surfaces; and land subdivision. Significant Redevelopment – means development that would add 5,000 or more square feet of impervious surface on an already developed site. Significant redevelopment includes, but is not limited to: • Expansion of a building footprint; • Addition of a building and/or structure; • Addition of an impervious surface that is not part of a routine maintenance activity such as construction of a new parking lot. Priority Project • Residential development of 10 units or more • Commercial and industrial development greater than 100,000 square feet including parking areas. • Restaurant where the land area of development is 5,000 square feet or more including parking areas. • Hillside development on 10,000 square feet or more, which is located on areas with known erosive soil conditions or where the natural slope is 25 percent or more. • Parking lot area of 5,000 square feet or more, or with 15 or more parking spaces, and potentially Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 exposed to urban runoff. • All Significant redevelopment projects, where significant redevelopment is defined as the addition of 5,000 or more square feet of impervious surface on an already developed site. There are no Environmentally Sensitive Areas within the City of Anaheim or within 200 feet of the City limit lines. Non-Priority Project – means a new development or equivalent City of Anaheim capital project that does not qualify as a priority project and • Requires discretionary action (i.e. public hearing before the City Council, Planning Commission, Zoning Administrator or City Engineer) that will include a precise plan of development, except those projects exempted by the Water Quality Ordinance (i.e. Chapter 10.09 of the Anaheim Municipal Code exempts exempt) Or ; • Requires a non-residential plumbing permit (a municipal, commercial or residential plumbing permit, excluding potable water or sewage – typically for gasoline piping systems). PRELIMINARY/CONCEPTUAL WATER QUALITY MANAGEMENT PLAN – INITIAL SUBMITTAL A Preliminary Water Quality Management Plan is required for new development and significant redevelopment projects that require approval by the Zoning Administrator, Planning Commission or City Council. Applicants are encouraged to submit the Preliminary WQMP concurrently with the PREFILE submittal. The Preliminary WQMP must be approved prior to filing for the public hearing. For private developments that do not require discretionary approval, developers are encouraged to submit a Preliminary WQMP The submittal for the Preliminary WQMP shall consist of the following: 1. Three (3) copies of Preliminary Water Quality Management Plans. The plan must include Site Design Best Management Practices (BMPs) and Treatment Control BMPs. The Source Control BMPs and BMP Maintenance can be excluded from the Preliminary WQMP and can be added when the Project WQMP is submitted. 2. Three (3) copies of the following items a. A conceptual grading plan b. A preliminary drainage report, including hydrology calculations, map, and calculations for sizing treatment control Best Management Practices (BMPs c. A preliminary geotechnical report 3. A plan review deposit in the amount approved by City Council Resolution and listed in the current fee schedule. PROJECT WATER QUALITY MANAGEMENT PLAN – INITIAL SUBMITTAL Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 The initial submittal of the Project WQMP shall consist of the following: 1. Three (3) copies of Water Quality Management Plans prepared according to 2. Three (3) copies of the grading plan package including a. The Grading Plan b. The Drainage Report, including hydrology calculations, map, and hydraulic calculations for storm drain plans and sizing treatment control Best Management Practices (BMPs). The drainage study shall conform to the requirements listed in the City’s Drainage Design Manual. c. The Geotechnical Report 3. A plan review deposit in the amount approved by City Council Resolution and listed in the current fee schedule. Incomplete plans will not be reviewed or processed, the civil engineer will be notified and the WQMP package will be returned. The project WQMP must be approved prior to approval of the grading plan, subdivision map or issuance of building permit whichever occurs first. III. WATER QUALITY MANAGEMENT PLANS FORMAT The Water Quality Management Plan shall be prepared in conformance to the requirements of Section 7 “New Development/Significant Redevelopment” of the Orange County 2003 Drainage Area Management Plan. The City of Anaheim is in the Santa Ana Region. The DAMP is available on the County’s Stormwater Program website www.ocwatershed.com Link to the Stormwater section and click on the Documents section on the left side of the page. The following items are specific to the City of Anaheim: Watershed and Pollutants of Concern. The City of Anaheim contains portions of four watersheds within its boundaries. The watersheds are: o Coyote Creek (Watershed A) o Carbon Creek (Watershed B) o Westminster (Watershed C) o Santa Ana River (Watershed E) The watershed descriptions and known pollutants of concern are listed in Exhibit A for incorporation into the WQMP. The civil engineer/designer shall add any additional information that becomes available during project research. The Watershed Map is available on the Development Services website or can be picked up at the Subdivision Services counter. The maps in Figures 1 and 2 illustrate watershed delineation and portions of watersheds (A, B, C, and E) that fall within the City of Anaheim’s boundaries. These watersheds are based on hydrologic areas delineated by the Regional Water Quality Control Board (RWQCB) in the Water Quality Control Plan for the Santa Ana River Basin (Basin Plan). The Storm Drain Key Map displays the major storm drains and waterways in the City of Anaheim as well as Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 the four major watersheds to which the City drains. The Storm Drain Key Map is available on the Development Services website or can be picked up at the Subdivision Services. With regard to drainage from outside of Anaheim, the greatest volume of flow by far is attributed to dry weather flow in the Santa Ana River (primarily fed by wastewater treatment plants upstream in Riverside County) and intermittent large flows in the River from storm events. Additionally, a small portion of the flow in Carbon Creek comes to Anaheim from the Cities of Fullerton, Placentia and Yorba Linda. Anaheim is only tributary to the Coyote Creek and Westminster watersheds, draining to them, rather than receiving flow from outside its boundaries, as is the case with the other two watersheds. Figure 1 Watersheds and City Boundaries of Orange County Source: http://www.ocwatersheds.com Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 Figure 2 Watersheds Portions That Fall Within City of Anaheim Boundaries Source: http://www.ocwatersheds.com Site Characteristics The City of Anaheim is divided into 45 Drainage Districts. Identify which drainage district the site is within. Include a copy of the district map and a project Plot Plan showing drainage flow arrows and how the drainage ties to drainage of surrounding properties. Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 SITE DESIGN BEST MANAGEMENT PRACTICES No exceptions are noted at this time. SOURCE CONTROL BEST MANAGEMENT PRACTICES Routine Non-Structural Source Control BMPs The City of Anaheim Fire Department has oversight for BMPS N5 (Title 22 CCR Compliance), N7 (Spill Contingency Plan), N8 (Underground Storage Tank Compliance), N9 Hazardous Materials Disclosure Compliance and N10 (Uniform Fire Code Implementation) pertain. Routine Structural Source Control BMPs • Design Trash Storage Areas to Reduce Pollutant Introduction See City of Anaheim Public Works Standard Detail. The project civil engineer may design a project specific area as conditions warrant. • Use Efficient Irrigation Systems and Landscape Design See Anaheim Municipal Code Chapter 10.19 Landscape Water Efficiency TREATMENT CONTROL BEST MANAGEMENT PRACTICES No exceptions to the Orange County DAMP have been identified at this time. ONGOING STORMWATER BMP MAINTENANCE No exceptions have been identified at this time V. PLAN CHECKING A. FIRST PLAN CHECK Plans will be scheduled for plan checking in the order they are received. The first plan check will be thorough and every attempt will be made to mark all plan deficiencies (except in those cases where the plan is incomplete or unclear). The designer will be notified as soon as the plan check is complete and ready for pick-up. The first plan check will take approximately 3-4 weeks. When the plan checking backlog exceeds an estimated 3 weeks, the plan may be sent to a consulting engineer that has contracted with the City. All checking done by a consulting engineer will be returned to the City for review before being forwarded to the designer. The designer will be notified as soon as the plan check is complete and ready for pick-up. All plan checks will be returned with a letter or checklist listing items to be submitted with the next plan check. Items marked "required for further processing" must be submitted with the next plan check. Water Quality Management Plan Procedures City of Anaheim JANUARY 2006 C. SUBSEQUENT SUBMITTALS Corrected plans will not be accepted for rechecking when items "required for further processing" are missing. It shall be the responsibility of the designer and/or developer to submit all items together with the corrected plans and previous check print. Subsequent plan checks will be completed in approximately three weeks. The previous check print will be used as a guide for rechecks, the entire plan will be rechecked only in instances where the first check was incomplete or unclear. The designer will be notified as soon as the plan check is complete and ready for pick up. In an effort to expedite the project, the plan checker assigned to the project will contact the developer and request a meeting with the designer and the developer if the plans are not ready for approval after the third plan check. VI. WQMP APPROVAL The plan checker will request two (2) copies of the Water Quality Management Plan with signature of the owner/developer in the plan check letter when the corrections requested are minor and will be sufficient to complete the plans. After a final check has been made to verify that all corrections have been incorporated into the WQMP, the WQMP will be stamped approved. One stamped copy will be returned to the owner/developer. The second copy will be retained in the City Records Section. VII. REVISIONS All changes to an approved WQMP must be submitted and approved by the City as a revision. Submit the following items to process a revision: 1) Two (2) copies of the revised WQMP, clearly identifying the items that are proposed to be revised. 2) A checking deposit in an amount determined by the City based on the estimated time for review.

Coyote Creek, its main tributary, flows from Riverside County to the San Gabriel River. Coyote Creek Watershed is highly urbanized with residential, commercial, and industrial development. There are currently no impaired water bodies within this watershed, however, Coyote Creek ultimately empties into Reach 1 of the San Gabriel River, which is impaired for abnormal fish histology, algae, and high coliform count on Region 4’s 2002 303(d) list. Carbon Creek, Watershed B – This watershed covers 21.4 square miles in west Orange County. Carbon Creek, its main tributary, begins in the foothills and empties into the San Gabriel River. Like Coyote Creek Watershed, the watershed area is highly urbanized with residential, commercial, and industrial development. There are currently no impaired water bodies within this watershed, however, Carbon Creek ultimately empties into Reach 1 of the San Gabriel River, under Los Angeles County jurisdiction, which is impaired for abnormal fish histology, algae, and high coliform count on Region 4’s 2002 303(d) list. Westminster, Watershed C – This watershed covers 74.1 square miles in the southwestern corner of Orange County. Surface water from the southwestern portion of Anaheim drains through the storm drain system to the Anaheim Barber City Channel, which connects to the Bolsa Chica Channel, and drains to Huntington Harbour with its ocean outlet through Anaheim Bay. The Westminster watershed is mostly urbanized and lies on a level coastal plain. Land use is primarily comprised of residential and commercial development, but also includes military, light industrial, schools, parks, and transportation facilities. Tidal influence extends about two miles inland in the lower portion of Bolsa Chica Channel. Impaired water bodies within this watershed include Seal Beach, impaired for enterococci, Huntington Harbour, impaired for pathogens, metals (copper, nickel), pesticides (dieldrin), and priority organics (PCBs), Anaheim Bay, impaired for metals (copper, nickel), pesticides (dieldrin), and priority organics (PCBs), and Bolsa Chica wetlands, impaired for metals (copper, nickel). Santa Ana River, Watershed E – This watershed covers 153.2 square miles in Orange County, including most of the eastern portion of Anaheim. Santa Ana River begins 75 miles away in the San Bernardino Mountains, crossing through eastern Anaheim before emptying into the Pacific Ocean. Impaired water bodies within this watershed include Reach 4 of Santiago Creek, impaired for salinity, TDS, and chlorides, and Silverado Creek, impaired for pathogens, salinity, TDS, and chlorides. Both Santiago Creek Reach 4 and Silverado Creek are upstream of the City of Anaheim.

(Petra) is presenting herein the results of our geotechnical investigation of the subject property. The purposes of this investigation were to determine the nature of subsurface soils, to evaluate their in-place characteristics, to provide geotechnical recommendations with respect to site clearing and grading, and for design and construction of building foundations. SITE LOCATION AND DESCRIPTION The subject property (Tentative Tract 17944) is located at the current address of 910 South Western Avenue in Anaheim, California. The property is bounded on the west by South Western Avenue, on the north and east by single family residences, and to the south by multi-family developments. For the approximate location of the site in relation to nearby landmarks, please see Figure 1 (Site Location Map). The subject property is a rectangular-shaped lot that was recently occupied by a single-family residence, detached garage, swimming pool, asphalt driveway, and other ancillary construction. The residence has recently been demolished and only the swimming pool, portions of the asphalt driveway, and remnant portions of the building foundations remain. The lot measures approximately 275½ feet by 219 feet with no sloped boundary conditions. The site exhibits a relatively level topography and lies at an approximate elevation of 64 to 65 feet above mean sea level (MSL). PROPOSED CONSTRUCTION AND GRADING Based on Tentative Tract Map No. 17944 plan prepared by Mayers & Associates Civil Engineering, Inc., dated April 16, 2019, the existing single-family residence structure and associated improvements were demolished in order to construct twelve new two-story single-family residences within the subject site. It is expected that the new residences will be of wood-frame construction and will be supported on conventional foundations (i.e., concrete continuous and spread footings) with floor slabs constructed on grade. No subterranean levels are anticipated. Associated site improvements are likely to include new masonry block walls, block walls retaining a maximum of 1 foot, concrete driveways, walkways and patio slabs, surface and subsurface drainage controls, and landscape areas. Based on the grading plan, design fills of approximately 1.0 to 1.5 feet are generally expected to reach pad grade for the new residences. However, fills to depths of 5 to 10 feet will be required to reach pad grade within the area of the existing pool . However, it should be noted that the ultimate depths of fill throughout the site will be greater due to th e required remedial grading involving overexcavation and recompaction of existing low-density surface soils PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 2 and disturbed soils resulting from the demolition and clearing operations. Recommendations for site grading, and for design and construction of building foundations, are presented in the "Conclusions and Recommendations" section of this report. SUBSURFACE EXPLORATION Our previous subsurface exploration was performed on April 10th and 17th of 2019 and involved the following: • Drilling of four (4) 8” diameter hollow stem auger borings (B-1 through B-4) to depths ranging from approximately 21.5 to 51.5 feet below the existing ground surface. • Advancing four (4) CPT soundings (CPT-1, CPT-2, CPT-3, and CPT-4) to depths of approximately 65 feet. • One pilot percolation test (P-1) was drilled to a depth of 3 feet using the 8” diameter hollow stem auger to observe the infiltration characteristics of subsurface materials that will be utilized in design of a potential infiltration system. The results of this test are provided in the Conclusions and Recommendations section of this report Soil materials encountered in the borings were visually classified and logged in accordance with the Unified Soil Classification System. The approximate locations of the CPT soundings, exploratory borings, and percolation test are shown on the attached geotechnical map (Figure 2), and descriptive exploration logs are presented in Appendix A. Associated with the subsurface exploration was the collection of bulk and relatively undisturbed samples of the on-site soil materials for laboratory testing. The undisturbed samples were obtained using a 3-inch, outside-diameter, modified California split-spoon soil sampler lined with 1-inch-high brass rings. The central portions of the driven core samples were placed in sealed containers and transported to our laboratory for testing. Bulk and ring samples were transported to the laboratory for testing. A modified California split-spoon soil sampler was advanced 18-inches at the indicated depths by a hollow stem auger drill rig using repeated blows from a 140 lb. hammer dropping 30 inches. The number of blows were recorded in 6 inch increments for each 18-inch interval evaluated. In addition to the above sampling method, Standard Penetration Tests (SPT's) were also performed at selected depth intervals in general accordance with the American Society for Testing Materials (ASTM) Standard Procedure D 1586. This method consists of mechanically driving an unlined standard split-barrel sampler 18 inches into the soil with successive 30-inch drops of the 140-pound automatic trip hammer. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 3 Blow counts for each 6-inch driving increment were recorded on the exploration logs. The number of blows required to drive the standard split-spoon sampler for the last 12 of the 18 inches was identified as the uncorrected standard penetration resistance (N). Disturbed soil samples from the unlined standard split- spoon samplers were placed in plastic bags and transported to our laboratory for testing. LABORATORY TESTING To evaluate the engineering properties of site soils, several laboratory tests were previously performed on selected samples considered representative of those encountered. Previous laboratory tests included the determination of in-situ dry unit weight and moisture content, laboratory maximum dry density and optimum moisture content, expansion index, Atterberg limits, consolidation, #200 sieve analysis, soluble sulfate and chloride contents, pH, resistivity, and shear strength analysis. A description of laboratory test criteria is given in Appendix B. Test data are summarized in Appendix B and test data are summarized on Plate B-1 and on the Exploration Logs (Appendix A). An evaluation of the data is reflected throughout the "Conclusions and Recommendations" section of this report. FINDINGS Regional Geology The site is situated along the southwesterly margin of the Orange County Coastal Plain, a relatively broad lowland area that was formed through alluvial aggradations and the formation of coalescing alluvial fans which were deposited along the ancestral Santa Ana River during late Quaternary time. The Coastal Plain bounded on the northeast by an alignment of highland areas and foothills (including the Puente and Coyote Hills), and on the southwest by a succession of low coastal hills and mesas that are topographic expressions of deformation along the Newport-Inglewood structural zone. Published geologic maps indicate that the subject site and adjacent lowland areas are underlain by late Quaternary-age, unconsolidated alluvial fan and flood plain deposits. In the area of the subject property, these geologically young materials extend locally to maximum depths on the order of 90 feet (Sprotte and others, 1980), and are unconformably underlain by eroded late Pleistocene-age terrace deposits and then by marine and littoral sedimentary bedrock of the San Pedro Formation. The referenced literature indicates that the alluvial and flood plain materials beneath the area of the subject site generally consist of alternating layers of silt, sand and clay. These native materials are overlain locally by artificial fill where previously existing natural grades have been modified as part of recent urbanization. This subsurface profile was generally confirmed during the site-specific investigation recently conducted by our firm. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 4 Local Geology and Subsurface Conditions As shown on the CPT sounding and boring logs included in Appendix A, our subsurface investigation within the subject site encountered alluvial deposits (map symbol Qal) that extend to the depth of our investigation (65 feet). These materials consist predominantly of interlayered loose to dense, fine-grained sand, silty sand and clayey sand, and soft to locally firm silt, sandy clay and clay. The moisture content of these native soils varies from slightly moist to saturated with moisture content generally increasing with depth. Laboratory testing of relatively undisturbed samples of alluvial soils yielded in-place dry densities ranging from 59.1 to 110.4 pounds per cubic foot. Undocumented artificial fill (Afu) was encountered within all of the exploratory points drilled on site to depths of approximately 1 to 2-feet. These fill materials were found to consist of dry to moist, loose, silty sand. Given the age of the existing residence, it is unlikely that the onsite fill materials were placed in accordance with current grading standards. In addition, no documentation has been made available that would indicate that fill placement was observed, tested and certified by a qualified geotechnical consultant. For this reason, all existing onsite fill is classified as "undocumented" for purposes of this investigation. Groundwater At the time of our subsurface investigation on April 10 and April 17, 2019, groundwater was recorded from pore pressure dissipation tests in our CPT soundings at depths ranging from approximately 10.5 to 14.0 feet below the existing ground. Similar groundwater depths ranging from 13 to 15 feet below ground surface were measured during the drilling of hollow stem auger borings B-1 and B-2. The Department of Conservation’s seismic hazard zone report (1998) puts historic high groundwater for the site at a depth of less than 10 feet. According to a Soil Vapor Investigation Report performed by Dudek on a site located at 3175 West Ball Road, Anaheim, approximately 150 feet south of the subject site, multiple groundwater monitoring wells were installed throughout the site. Groundwater measurements in November 2011 ranged from approximately 6 to 8 feet below ground surface. Previous measurements also took place at that site between 1988 and 2000 and measured groundwater ranged between 5.4 and 17.8 feet below ground surface. Expansive Soils Previous laboratory test results on the soils in the upper 5 feet indicated the onsite near surface soils were in the very low expansion category (EI less than 20). However, we did observe clayey soils generally below a depth of 7 feet, that would likely exhibit higher expansive characteristics if they were located nearer to PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 5 the ground surface. Foundations and exterior flatwork should be designed based on the soil’s expansive characteristics. Preliminary recommendations are provided in subsequent section of this report for both foundations and flatwork improvements. Grading operation may redistribute the positions of the expansive soils. Actual final design parameters for expansive soils should be determined upon completion of grading operations and laboratory testing of the finished pad soils. Flooding Not Related to Seismicity As part of this investigation, we conducted an independent review of the applicable FEMA flood insurance rate map for the area of the subject site (Map No. 06059C0109J, effective December 3, 2009). This map indicates that the site of the proposed construction is located within an area that is designated as Flood Zone X, meaning that one or more of the following conditions is present (FEMA, 2009): • The site is located within an area having a 0.2% annual chance flood; • The site is located within an area having a 1% annual chance flood with an average flood depth of less than 1 foot or with a drainage area of less than 1 square mile; • The site is located within an area protected from the 1% annual chance flood by a levee system. Methane Gas The property is not located in an area where petroleum exploration and production has occurred in the past. According to an online source, the closest oil and/or gas exploration well (Charles T.B. Jones Well No. 1, API: 05901033) was located approximately 1 mile to the west. This well is now listed as idle (http://maps.conservation.ca.gov/doggr/ last accessed June 13, 2019). The site is not known to be located within a designated oil field and not in an area where hazards associated with surface seepage of methane gas from natural or artificial sources have been identified. Tar Seeps Natural tar and oil seeps typically occur as deposits of pure oil, asphaltum, semi-solid bitumens or combinations of these substances that are mixed with surficial organic debris, clay, peat and other materials. No evidence of such seepage was observed during our surface reconnaissance of the site, nor was any tar- like substance present in any of the soil samples retrieved during our subsurface investigations. No onshore seeps are mapped onsite or in the vicinity (DOGGR, 2019). In addition, no historical occurrences of tar seeps within the site were brought to our attention by onsite facilities maintenance personnel. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 6 PERCOLATION TESTING Percolation testing was previously conducted in Exploratory Boring P-1 in accordance with County of Riverside Department of Environmental Health (RCDEH) test procedures and the guidelines presented in Appendix VII of the County of Orange Technical Guidance Document for WQMPs. The Orange County Manual references the RCDEH percolation test methods as an acceptable method of obtaining site infiltration data. The “percolation rates” determined in accordance with the RCDEH test procedures are based on both horizontal (lateral) and vertical percolation. Therefore, to consider vertical percolation only, the “percolation rates” were converted to a reasonable estimate of the “infiltration rate” using the Porchet Method presented in Appendix VII of the referenced County of Orange Technical Guidance Document. Boring P-1 was converted to a percolation test hole prior to backfill of the boring. Following the drilling of this boring, a three-inch (I.D.) perforated PVC pipe was placed in the test hole. Open-graded gravel (approximately ¾-inch) was then placed within the annular space between the pipe and boring walls, including a 3-inch thick layer of gravel below the pipe. The gravel was backfilled to approximately 1 foot from the surface, and the remainder of the annular space was backfilled with boring cuttings. Clean water was then added to the boring to pre-soak the adjacent soils prior to performing the percolation test. The percolation test was conducted in a mix of silty sands that exist from the near-surface to below the base of the percolation test. Boring P-1 was drilled to a total depth of approximately 3 feet . The test hole was filled with clean water to approximately 1 foot from the ground surface. The drop in water level was measured at 30-minute intervals. From these readings, the percolation characteristics of the underlying alluvial deposits were estimated. The approximate location of the percolation test is shown on Figure 2 and percolation test results are presented in Appendix C and are summarized below in Table 1. TABLE 1 Percolation Test Results Test No. Soil Type1 (USCS) Depth of Hole (Feet) Measured 2 Percolation Rate (Minutes/Inch) Converted Infiltration Rate (It) 3, 4 per Porchet Method (Inches/Hour) P-1 SM 3 6.25 1 1 Interbedded Strata – see Boring Logs, Appendix A 2 RCDEH Test Procedure 3 Minutes/inch converted to inches/hour per Porchet Method 4 A minimum factor of safety of 2 should be applied to the converted infiltration rate per the OCPW LID Manual. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 7 Faulting The referenced geologic maps and literature indicate that no active faults are known to project through the property. Furthermore, the site does not lie within the boundaries of an earthquake fault zone as defined by the State of California pursuant to the Alquist-Priolo Earthquake Fault Zoning Act (Bryant and Hart, 2007). The Alquist-Priolo Earthquake Fault Zoning Act (AP Act) defines an active fault as one that has had surface displacement within Holocene time (about the last 11,000 years). The main objective of the AP Act is to prevent the construction of dwellings on top of active faults that could displace the ground surface resulting in loss of life and property. According to the USGS Beta – Unified Hazard Tool (https://earthquake.usgs.gov/hazards/interactive/) and/or the 2010 CGS ‘Fault Activity Map of California’, the closest active fault to the site is the onshore segment of the Newport-Inglewood fault that is located approximately 11.0 kilometers (6.8 miles) southwest of the subject site. The Newport-Inglewood fault consists of a series of parallel and en-echelon, northwest-trending faults and folds extending from the southern edge of the Santa Monica Mountains southeast to the offshore area of south Orange County. This zone has a history of moderate to high seismic activity and has generated several historic earthquakes greater than magnitude 4.0, including the March 11, 1933 Long Beach earthquake (magnitude 6.3), the October 21, 1941 earthquake (magnitude 4.9), and the June 18, 1944 earthquake (magnitude 4.5). Another category of fault known as a "blind thrust" became recognized as a significant seismic hazard as a result of the 1987 magnitude 6.0 Whittier Narrows earthquake. Blind thrusts are concealed beneath the earth’s surface and are defined as dip-slip faults that tend to fold and/or uplift the near surface sediments during moderate to large magnitude earthquakes (Shaw and Suppe, 1996). In 1994 the magnitude 6.7 Northridge earthquake occurred along what researchers have interpreted as a south-dipping thrust ramp beneath the San Fernando Valley. Together, these events caused more than $25 billion in property damage and clearly demonstrate the risks that blind thrusts pose to the greater Los Angeles metropolitan area. Recent structural models of the Los Angeles basin suggest that deep-seated, blind thrust sheets underlie portions of Orange and Los Angeles Counties. These structures are apparently accommodating north-south compression with slip rates of several millimeters per year (Hauksson, 1992; Petersen and Wesnouski, 1994). The Puente Hills and Upper Elysian Park blind thrust systems represent two such blind thrusts that are reported to extend below and in close proximity to the site (6.3 kilometers (3.9 miles) and 6.5 kilometers (4.1 miles), respectively) (Dolan et al., 2003, Shaw et al., 2002, and Oskin et al. 2000). A similar system underlies the San Joaquin Hills (Grant et al., 1999). Structural models and seismicity values for these three PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 8 blind thrust systems and the Northridge blind thrust have been incorporated into the California Geological Survey seismic model, which was updated in April 2003 (Cao, et al., 2003). Seismic Hazard Zones Based on our review of the published Seismic Hazard Zone Report for the U.S.G.S. Los Alamitos 7.5- minute quadrangle (CDMG, 1997), the subject site lies within a designated Liquefaction Hazard Zone. Given the essentially flat topography that characterizes this area of Anaheim, the site has not been included within a State-designated landslide hazard zone. The location of the site in relation to the liquefaction hazard zones is shown on Figure 3. Seismically-Induced Flooding The types of seismically induced flooding which may be considered as potential hazards to a particular site normally includes flooding due to a tsunami (seismic sea wave), a seiche, or failure of a major reservoir or other water retention structure upstream of the site. Since the site lies 12.5 kilometers inland from the Pacific Ocean at an average elevation of approximately 65 feet above sea level, and does not lie in close proximity to an enclosed body of water the probability of flooding from a tsunami or seiche is nonexistent. In addition, the site is not located within a designated tsunami inundation area as identified on the tsunami inundation maps recently published by the California Emergency Management Agency (CEMA, 2009). However, the site does lie downstream of a major reservoir (the Prado Dam) and is within its inundation area according to the Orange County General Plan Figure IX-9. Seismic Design Parameters Earthquake loads on earthen structures and buildings are a function of ground acceleration which may be determined from the site-specific ground motion analysis. Alternatively, a design response spectrum can be developed for the site based on the code guidelines. To provide the design team with the parameters necessary to construct the design acceleration response spectrum for this project, we used a computer application, which is available on the United States Geological Survey (USGS) website, http://geohazards.usgs.gov/. Specifically, the Design Maps web site http://earthquake.usgs.gov/designmaps/us/application.php was used to calculate the ground motion parameters. To run the above computer application, site latitude, longitude, risk category and knowledge of “Site Class” are required. The site class definition depends on the average shear wave velocity, Vs30, within the upper 30 meters (approximately 100 feet) of site soils. A shear wave velocity of 600 to 1,200 feet per second (Site PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 9 Class D) for the upper 100 feet was used for the site based on the CPT soundings data and engineering experience and judgment. The following table, Table 2, provides parameters required to construct the site-specific acceleration response spectrum based 2019 CBC guidelines. PEPPERWOOD PLACE LP June 14, 2021 910 S.

PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 11 Site-Specific Liquefaction Analysis In April 1991, the State of California enacted the Seismic Hazards Mapping Act (Public Resources Code, Division 2, Chapters 7-8). The purpose of the Act is to protect the public safety from the effects of strong ground shaking, liquefaction, landslides, or other ground failure. The Act defines mitigation as “… those measures that are consistent with established practice and reduce seismic risk to acceptable levels.” Acceptable level of risk is defined as “that level that provides reasonable protection of the public safety, though it does not necessarily ensure continued structural integrity and functionality of the project [California Code of Regulations; Section 3721 (a)]”. In the context of that Act, mitigation of the potential liquefaction hazards at this site to appropriate levels of risk can be accomplished through appropriate foundation and/or subsurface improvement design. Based on site exploration, this site is considered susceptible to seismic liquefaction. This is due primarily to the documented presence of unconsolidated granular (sandy) soils in the area, the relatively shallow groundwater conditions, and to the proximity of seismic sources. For this reason, a site-specific liquefaction analysis was performed as part of this study. Assessment of liquefaction potential for a particular site requires knowledge of a number of regional as well as site-specific parameters, including the estimated design earthquake magnitude, and the associated probable peak horizontal ground acceleration at the site, subsurface stratigraphy and soil characteristics. Parameters such as estimated probable peak horizontal ground acceleration can readily be determined using published references, or by utilizing a commercially available computer program specifically designed to perform a probabilistic analysis. On the other hand, stratigraphy and soil characteristics can only be accurately determined by means of a site-specific subsurface investigation combined with appropriate laboratory analysis of representative samples of onsite soils. Propagating earthquake waves induce shearing stresses and strains in soil materials during strong ground shaking. This process rearranges the structure of granular soils such that there is an increase in density, with a corresponding decrease in volume, which results in vertical settlement. Dynamic settlement has been well documented in wet, sandy deposits undergoing liquefaction (see Tokimatsu and Seed, 1987) and in relatively dry sediments as well (Stewart et al, 1996). Specific methods to analyze potential wet and dry dynamic settlement are reported in Tokimatsu and Seed (1987), and specifically dry settlement in Pradel (1998) and Stewart et al. (2001; 2002) respectively. Most of the referenced papers focus on the seismic effects on dry, clean sands of a uniform grain size, though several reports extend the literature to fine- grained soils (Stewart et al., 2001 & 2002). State guidelines for evaluating dynamic settlement are provided in the California Geological Survey Special Publication 117A (CGS, 2008). PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 12 We have used a more conservative value of 8 feet for our liquefaction analysis, because offsite groundwater measurements were recently noted slightly higher than the value for the historical high groundwater depth noted on the state maps. Analyses Using CPT Results We performed four (4) CPT soundings at the site for use in the liquefaction analysis. Our analysis using the CPT data provides continuous penetration resistance data rather than borehole data using SPT sampling that must be averaged over discrete sampling increments (e.g., 5 or 10 feet). A variety of computer programs are available that were developed specifically for liquefaction and seismic settlement analyses. For purposes of this study, we selected the commercially available software program Cliq Version 3.0.2.1 (Geologismiki, 2019) that implements updated versions of the NCEER procedure as recommended by Dr. Peter Robertson (2010), or that of Professors Idriss and Boulanger (2008, 2014). The procedures were based on the methods originally recommended by Seed and Idriss (1982). Calculations using CPT data are also provided in Appendix D. In our analysis from the CPT data, we utilized and adjusted Ic cutoff value of 2.9 as being more conservative based on some of our boring log information and Atterberg limits data. We assessed the liquefaction utilizing the “Clay Like” behavior allowance in the modified Robertson method; however, the results were less conservative than applying an adjusted Ic cutoff. Therefore, the results reported here are based on the Ic of 2.9 as the boundary between soil more likely to liquefy and cause ground settlement. Analysis Results and Assessment of Liquefaction Effects Section 1803.5.12.3 of the 2019 CBC requires the “assessment of potential consequences of liquefaction and soil strength loss, including, but not limited to” the following items, which we will discuss in the order that they appear in the code. CBC Section 1803.5.12.3 – 3.1 – Estimation of total and differential settlement; Analyses with groundwater assumed at 8 feet below the ground surface indicated that the main potentially liquefiable zone is at approximately 20 feet below the ground surface in CPT-s 2 and 4. Other thinner zones were noted within the other borings at various other depth. There does not appear to be a consistent zone across the site. A factor of safety of 1.3 was used in our analysis in accordance with the procedures of CGS publication SP117A. For CPT settlement we used the modifications to the NCEER procedure (adjusted Ic cutoff) to estimate the free field settlement. Tabulated results of the estimated settlement for this analysis method are provided in Appendix D of this report and are shown in Table 3 below. The results of the other methods are shown on PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 13 the summary comparison plot printouts. Please note, total settlement is based on the depth of our investigation. A photograph of the typical clayey silt/ silty clay soils at the site is shown below. Our judgement for the Ic cutoff was based on the CPT data and the boring data providing confirmation of the soil conditions present and likely to liquefy. Photograph 1 – Fine Grained Soils from Boring B-1 PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 14 TABLE 3 CPT # Method Total Settlement (in.) CPT-1 NCEER 1.1 CPT-2 NCEER 1.9 CPT-3 NCEER 2.0 CPT-4 NCEER 1.8 Based on the analysis results provided above, the estimated amount of dynamic differential settlement is approximately 0.9 inches over a horizontal span of 60 feet. This can be expressed as an angular distortion ratio of 1:800. This is based on the free field volumetric approach; additional settlement could occur due to structure loads. The free field settlement is the settlement based on only the characteristics of the ground and does not include any additional settlement that may be caused by structural loads. Surface Manifestation of Liquefaction Based on the method outlined by Ishihara (1985) and considering the depth of the liquefiable layer identified by the results of our exploratory drilling and CPT soundings, the thickness of the non-liquefiable layers above the liquefiable zone may be marginally sufficient to prevent surface manifestation of liquefaction (such as sand boils, ground fissures, etc.). Therefore, additional distress to structures located at the surface is not likely to occur beyond that which may be imposed by ground surface settlement. This is however, based on the more fine-grained soils nearer the surface that may be just under the cutoff and therefore could trigger, but are less likely to produce the volumes of subsurface water needed to manifest the sand boils etc. Implementation of the grading recommendations and foundation design requirements outlined later in this report will be necessary to provide adequate performance of the structures under these marginal conditions. CBC Section 1803.5.12.3 – 3.2 – Lateral soil movement; Given the generally flat topography at the subject site, the potential for lateral spreading is negligible. CBC Section 1803.5.12.3 – 3.3 – Lateral soil loads on foundations; Basement structures are not planned for this site, therefore lateral load effects on basement foundations are not applicable. CBC Section 1803.5.12.3 – 3.4 – Reduction in foundation soil-bearing capacity and lateral soil reaction; The soil cover between the proposed foundation and the liquefiable layer identified is marginally sufficient, as a result, the potential for liquefiable soils creating soil strength loss or a reduction in bearing capacity is reduced with the recommended mitigation measures. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 15 CBC Section 1803.5.12.3 – 3.4 – Soil downdrag and reduction in axial and lateral soil reaction for pile foundations; Pile foundations will not be utilized as the foundation for the proposed structure. Therefore, soil downdrag and reduction in axial and lateral soil reaction for pile foundations are not applicable. CBC Section 1803.5.12.3 – 3.5 – Increases in soil lateral pressures on retaining walls; Conceptual plans provided to date do not indicate the need for retaining walls at the site, therefore increases in soil lateral pressures on retaining walls are not applicable. CBC Section 1803.5.12.3 – 3.6 – Flotation of buried structures. Structures that enclose a void space such as pipelines, manholes, or buried vaults may be subject to buoyant forces if they are located within the layers below 10 feet from the ground surface where we noted that liquefaction was likely to occur for this site. Such structures may need to be anchored if they are not located within areas mitigated by remedial grading. CONCLUSIONS AND RECOMMENDATIONS General From a soils engineering and engineering geologic standpoint, the subject property is considered suitable for the proposed construction provided the following conclusions and recommendations are incorporated into the design criteria and project specifications. Grading Plan Review This report has been prepared without the aid of a finalized grading plan depicting the proposed grading and construction. Petra has been provided an updated tentative tract map dated February 22, 2021, and just recently a preliminary grading plan (plot dated June 4, 2021) for Tract 17944 prepared by Mayers & Associates. Therefore, the recommendations provided in this report should be considered tentative until a finalized grading plan is available and reviewed by the project geotechnical consultant. Additional recommendations and/or modification of the recommendations provided herein may be necessary depending on the results of the finalized grading plan review. Effect of Proposed Grading on Adjacent Properties It is our opinion that the proposed grading and construction will not adversely affect the stability of adjoining properties provided that the grading and construction are performed in accordance with the recommendations provided herein and in accordance with current standards of practice and all applicable grading ordinances. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 16 Primary Geotechnical Concerns Existing Undocumented Fill, Low Density Soils and Shallow Groundwater Low density, very soft native soils underlie the site at depth. In addition, groundwater was encountered at relatively shallow depths ranging from 10 to 15 feet below the ground surface. Therefore, placement of a relatively thick engineered fill mat positioned above the groundwater is proposed to support the relatively light loads of the single-family residences. Existing undocumented fill and the underlying native alluvial soils will require removal to a minimum depth of 7 feet below the ground surface prior to re-placement as compacted fill to design grade. Recommendations for remedial grading and for design and construction of foundations are provided in the “Earthwork” and “Foundation Design Guidelines” sections of this report. Earthwork Earthwork Specifications All earthwork and grading should be performed in accordance with the applicable requirements of the City of Anaheim and in accordance with the following recommendations prepared by this firm. Site Clearing All trees, weeds, and landscape vegetation existing within the areas of proposed grading and construction should be stripped and hauled off site prior to commencement of earthwork operations. Trees and large shrubs, when removed, should be grubbed out to include their stumps and major root systems. During site grading laborers should be provided to clear from fill soils any roots, tree branches, and other deleterious materials missed during initial clearing and grubbing operations, as may be required. Any debris or trash within the area of proposed construction should be removed and disposed of offsite. All structural materials, not protected in place, associated with the previously existing improvements (pool, flatwork, patios, and planters) on site should also be removed. Any existing utility lines that are to be abandoned should be removed and the resultant excavations backfilled with properly compacted fill. It is our understanding that the existing pool will be removed in its entirety. The entire existing pool shell, bond beam and coping should be demolished and removed from the site. In addition, all pool utility lines should be exposed, demolished and removed from the site. The excavations created by the removal of the swimming pool shell and pool utility lines should be cleared of all loose soil and debris and then shaped to provide access for backfilling and compaction equipment. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 17 Portions of the existing pool may be deeper than the current groundwater levels. Therefore, dewatering may be required as groundwater levels could be different than our current measurements, and could also affect the demolition and removal of the pool. Our firm should be notified at the appropriate times to provide observation and testing services during clearing operations to document compliance with the above recommendations. In addition, should any buried structures or unusual or adverse soil conditions be encountered during clearing operations or during grading that are not described or anticipated herein, these conditions should be brought to the immediate attention of our firm. Ground Preparation - Removals General It should be understood that low density, very soft native soils underlie the site at depth. Therefore, in order to provide suitable and relatively uniform support for the proposed structural foundations and exterior site improvements, it is recommended that the existing fill and native soils be over-excavated to a minimum depth of 7 feet from the existing ground surface, or 5 foot below the bottoms of proposed structural footings, whichever is deeper, and the excavated material replaced as properly compacted fill. This may be accomplished by removing the upper 6.5 feet of existing fill and alluvial soils, and then reprocessing the next underlying 6 inches in place. That is, prior to replacing the excavated materials as compacted fill, the exposed bottom surface should be scarified to a depth of at least 6 inches, watered as necessary to achieve slightly above optimum moisture conditions, and then recompacted in-place to a minimum relative compaction of 90 percent of the applicable laboratory maximum density standard as determined in accordance with the current version of ASTM Test Method No. D 1557. In order to provide adequate support for sidewalks, patios, street, and similar perimeter improvements, overexcavation and recompaction of the existing ground surface should essentially extend from property line to property line within the area of proposed construction; however, consideration should be given to the protection of adjacent structures as described in the following section of this report. As noted in the exploratory logs, soft and moist silty sand soils were generally encountered within the upper 7 feet below the ground surface. However, clayey soils were generally encountered immediately below the depth of 7 feet below the ground surface. Therefore, care should be exercised by the grading contractor when running large equipment on the bottom surface once the depth of overexcavation is reached in order to reduce the likelihood of destabilization/pumping of the bottom. Further recommendations for unstable bottom conditions are noted below. Once the bottom surface is exposed, the project Engineering Geologist PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 18 should be notified to allow for observation and documentation of the bottom. Further recommendations may be provided in the field if unsuitable conditions are observed. It is possible that localized areas may be encountered where low-density soils extend to depths in excess of 7 feet below the surface. Where such materials are encountered during grading, deeper remedial excavation will be required to remove all low-density soils and soils that are suitable for support of compacted fills and building loads. The actual depth of required remedial removals should be determined during grading based on field observations by a representative of this firm. Existing Swimming Pool As mentioned above, site clearing operations should include removal of the previously existing pool within the easterly portion of the site. In addition, all existing fill soils associated with the pool should be removed to expose undisturbed native alluvial materials. The native alluvial soils existing at and below a depth of 8 feet in the area of the existing swimming pool and associated improvements are composed primarily of sandy silts and clayey silts that have high in-place moisture contents and relatively low in-place densities. Based on our experience with similar soils in the generally vicinity of the project, the materials exposed during the pool excavation could be very sensitive to point loadings and vibration and therefore may tend to quickly lose their strength under the weight of rubber-tired and/or track-mounted grading equipment. For this reason, it will be important to minimize disturbance of the native soils exposed in the temporary excavation bottom during remedial grading within the swimming pool area as well as in other removal bottom areas. In addition, it may become necessary to stabilize the bottom surface in order to achieve adequate compaction of new fill soil to be placed within the excavation (see below). Stabilization of Yielding Bottom Surfaces As noted above the native alluvial soils existing at and below a depth of 8 feet in the area of the existing swimming pool and associated improvements are composed primarily of sandy silts and clayey silts that have high in-place moisture contents and relatively low in-place densities. These materials can be very sensitive to point loadings and vibration and therefore tend to quickly lose their strength under the weight of heavy rubber-tired equipment. Similar strength loss may also occur under the loads and vibration imposed by track-mounted equipment. For this reason, it will be important to minimize disturbance of the native soil exposed in the temporary excavation bottoms during remedial grading . In addition, it may become necessary to stabilize the bottom surfaces in some locations prior to fill placement in order to achieve adequate compaction of the fill soil to be placed within the excavation. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 19 Our previous experience indicates that yielding bottom surfaces within overexcavated areas may be stabilized (as required) by placement of a layer of woven geotextile material within the removal bottom. Specific recommendations are provided in the following paragraphs. 1. The contractor should perform the remedial removals as specified in this report . Care should be taken to minimize disturbance of the native soils existing at the removal bottom elevation . Excessive vibration should also be avoided to prevent further loss of soil strength. The equipment utilized to excavate the area while minimizing disturbance and point loading of the removal bottom is left to the discretion of the contractor. 2. Once the removal bottom has been observed and documented by a representative of our firm and the bottom surface has been leveled, a layer of woven geotextile material (such as Mirafi HP-370, HP-570 or an approved equivalent) should be placed over the entire removal bottom (i.e., to the full horizontal limits of the overexcavated area) in accordance with the manufacturer’s specifications. The contractor should be familiar with, and adhere to, the geotextile manufacturer's specifications for installation of this material, including the required overlap between adjacent geotextile sections. 3. Once the geotextile mat has been installed within the removal area, the contractor should begin placing an approximately 12-inch-thick lift of fill material across the top of the mat, beginning from one edge of the excavation and working inward toward the center . No heavy equipment should be allowed to travel directly on the surface of the geotextile material. Once it has been confirmed that the yielding bottom surface has been adequately stabilized using the method described above, fill placement may proceed using conventional earthmoving equipment (preferably lightly-loaded, track-mounted equipment) in accordance with the recommendations provided in the referenced report by this firm. Although considered unlikely based on our past experience, it is possible that yielding bottom conditions could persist despite placement of the geotextile mat. Under such circumstances, it may become be necessary to place an approximately 18- to 24-inch-thick layer of crushed rock over the geotextile mat to further stabilize the bottom surface and allow proper compaction of the overlying fill soils. If required, the crushed rock should consist of ¾" to 1½" open-graded gravel, or other aggregate if approved by this firm. Protection of Adjacent Properties During remedial grading of the site, a temporary excavation with sidewalls varying up to approximately 7 feet high will be created during the over-excavation and re-compaction of the existing property. The sidewalls of this excavation are expected to expose artificial fill and native alluvium materials that consist of loose to medium dense, silty sands. In order to protect the existing structures located along the property lines, we recommend that temporary slopes not exceeding a height of approximately 2 feet may be tentatively planned at a vertical gradient. However, where these sidewalls exceed this height, the lower 2 feet may be cut vertical and the upper portions above a height of 2 feet should be cut back to a slope ratio PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 20 no steeper than 1:1, horizontal to vertical with the top of the cut located at least 12 inches away from the property line structures. During the preparation of the grading plan for the subject site, the project civil engineer should take into consideration the location and elevation of the footings of existing property line structures that are to be protected in-place. Grades within the site should not be lowered to the extent that they will have an adverse impact on the lateral stability of the existing property line structures unless mitigating measures such as shoring are implemented. Imported Soils If imported soils are required to complete the planned grading, these soils should consist of clean materials devoid of rock exceeding a maximum dimension of 4 inches, as well as organics, trash and similar deleterious materials. In addition, imported soils should exhibit an expansion index of less than 90 (a Medium expansion potential), as classified by ASTM procedures. Prospective import soils should be observed and tested by our firm prior to importing the soils to the site. It is recommended that the project environmental consultant also be notified so that they can confirm the suitability of the proposed import material from an environmental standpoint. Fill Placement and Testing New engineered fills should be placed in lifts not exceeding 6 inches in thickness, watered or air dried as necessary to achieve near optimum moisture conditions, and then compacted in place to a minimum relative compaction of 90 percent. Each fill lift should be treated in a similar manner. Subsequent lifts should not be placed until the preceding lift has been tested by the project geotechnical consultant to document that the required 90 percent relative compaction has been achieved. The laboratory maximum dry density and optimum moisture content for each change in soil type should be determined in accordance with Test Method ASTM D 1557. Geotechnical Observations Exposed bottom surfaces in each removal area should be observed by the project geotechnical consultant prior to placing fill. No fills should be placed without prior approval from the geotechnical consultant. The project geotechnical consultant should also be present on-site during grading operations to observe proper placement and compaction of fill, as well as to document compliance with the recommendations presented herein. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 21 Shrinkage and Subsidence An average shrinkage on the order of about 10 to 15 percent may occur when excavated onsite soils are replaced as properly compacted fill. A subsidence estimated between 0.10 and 0.15 feet may also be expected when exposed bottom surfaces in removal areas are scarified and re-compacted as recommended herein. The above estimates of shrinkage and subsidence are intended as an aid for project planners in determining the earthwork quantities. However, these estimates should be used with some caution since they are not absolute values. Post-Grading Considerations Site Drainage Positive surface drainage systems consisting of a combination of sloped concrete flatwork/asphalt pavement, sheet flow gradients, swales and surface area drains (where needed) should be provided around the building and within the planter areas to collect and direct all surface waters to an appropriate drainage facility as determined by the project civil engineer. The ground surfaces of planter and landscape areas that are located within 10 feet of building foundations should be sloped at a minimum gradient of 5 percent away from the foundations and towards the nearest area drains. The ground surfaces of planter and landscape areas that are located more than 10 feet away from building foundations may be sloped at a minimum gradient of 2 percent away from the foundations and towards the nearest area drains. Concrete flatwork surfaces that are located within 10 feet of building foundations should be inclined at a minimum gradient of 2 percent away from the building foundations and towards the nearest area drains. Concrete flatwork surfaces that are located more than 10 feet away from building foundations may be sloped at a minimum gradient of 1 percent away from the foundations and towards the nearest area drains. Surface waters should not be allowed to collect or pond against building foundations and within the level areas of the site. All drainage devices should be properly maintained throughout the lifetime of the development. Future changes to site improvements, or planting and watering practices, should not be allowed to cause over-saturation of site soils adjacent to the structures. WQBMP infiltration systems have been proposed at the site. The WQBMP concept is to maintain the site’s pre-development water runoff rates and volumes by implementing design techniques that detain surface runoff and direct the water into systems that infiltrate to the subsurface. This concept is in direct conflict with the geotechnical drainage recommendations presented above to collect surface runoff and transfer this water to an approved drainage device away from buildings and structures. As regulatory guidelines must be met, the project civil engineer will be required to design the site to meet the appropriate regulatory PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 22 standards; however the project civil engineer must also be cognizant of the geotechnical concerns with water infiltration adjacent to buildings and structure and design accordingly. A minimum setback of at least 15 feet between infiltrations systems and building foundations is suggested to help alleviate this conflict (See below). Bottomless Trench Drains When gravel filled bottomless infiltration systems are constructed near foundations, a potential exists for oversaturation of the foundation soils which conflicts with the intended purpose of onsite drainage facilities. In addition, it has been our experience that a leading cause of distress to buildings and foundations is due to poor management of water next to building foundations. Petra recommends a setback of at least 15 feet between any infiltration system and building foundations. If this setback distance cannot be maintained, then a modified foundation system may be required to alleviate any distress that could be caused by infiltration of water near the footing. A modified foundation system could consist of constructing deepened footings within 15 feet of the infiltration system and installing extra reinforcement. Design of a modified foundation system is referred to the project structural engineer. Utility Trench Backfill All utility trench backfill should be compacted to a minimum relative compaction of 90 percent. Onsite earth materials cannot be densified adequately by flooding and jetting techniques. Therefore, trench backfill should be placed in lifts no greater than 6 inches in thickness, watered or air-dried as necessary to achieve near optimum moisture conditions, and mechanically compacted in place to a minimum relative compaction of 90 percent. A representative of the project geotechnical consultant should probe and test the trench backfills to document that adequate compaction has been achieved. As an alternative for shallow trenches where pipe or utility lines may be damaged by mechanical compaction equipment, such as under building floor slabs, imported clean sand having a sand equivalent (SE) value of 30 or greater may be utilized. The sand backfill materials should be watered to achieve near optimum moisture conditions and then tamped into place. No specific relative compaction will be required; however, observation, probing, and if deemed necessary, testing should be performed by a representative of the project geotechnical consultant to verify an adequate degree of compaction. If clean, imported sand is to be used for backfill of exterior utility trenches, it is recommended that the upper 12 inches of trench backfill materials consist of properly compacted onsite soil materials. This is to mitigate infiltration of irrigation and rainwater into granular trench backfill materials. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 23 Where an interior or exterior utility trench is proposed parallel to a building footing, the bottom of the trench should not be located below a 1:1 plane projected downward from the outside bottom edge of the adjacent footing. Where this condition exists, the adjacent footing should be deepened such that the bottom of the utility trench is located above the 1:1 projection. Where utility trenches cross under a building footing, these trenches should be backfilled with on-site soils at the point where the trench crosses under the footing to reduce the potential for water to migrate under the floor slabs. Foundation Design Recommendations Due to the potential for liquefaction and susceptibility to differential settlement, we have provided recommendations for a conventional shallow foundation. Other foundation system options, such as mat or post-tension, can be provided upon request. Static Settlement Under the above recommended bearing values, total static settlements due to new building loads are expected to be less than ½ of an inch, and differential settlement between adjacent footings is expected to be less than ¼ of an inch over a span of 40 feet. The majority of the anticipated settlement is expected to take place during construction as building loads are applied. However, as described previously, the site is located within an area that has the potential for liquefaction-induced settlement. Therefore, foundations within the site should be designed to withstand maximum total settlements for both static and dynamic conditions. Dynamic (Seismically-Induced) Settlement As stated previously in this report, the maximum differential settlement was found to be approximately 0.9 inch over a horizontal span of approximately 60 feet, with a corresponding equivalent angular distortion ratio of approximately 1:800. Therefore, we recommend that the foundation be designed based on total settlements on the order of 2-½ inches, with differential settlements on the order of 1-¼ inches over a span of 60 feet. This can be expressed as an angular distortion ratio of 1:575. The recommendations for design of the foundations for expansive soils should also help with alleviation of settlement and deformations from liquefaction. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 24 Lateral Resistance A passive earth pressure of 250 pounds per square foot, per foot of depth, to a maximum value of 2,500 pounds per square foot, may be used to determine lateral bearing resistance for footings. In addition, a coefficient of friction of 0.30 times the dead load forces may be used between concrete and the supporting soils to determine lateral sliding resistance. The above values may be increased by one-third when designing for short duration wind or seismic forces. The above values are based on footings placed directly against compacted fill. In the case where footing sides are formed, all backfill placed against the footings should be compacted to at least 90 percent of maximum dry density. Guidelines for Footings and Slabs on-Grade Design and Construction The results of our laboratory tests performed on representative samples of near-surface soils within the site during our investigation indicate that these materials predominantly exhibit expansion indices that range from 0 to 50. The upper soils were very low, and the deeper soils may have more expansive characteristics. Additionally, designs with the following minimum recommendations my assist with resistance to liquefaction induced differential settlements. As such, the site soils are classified as "expansive" as defined in Section 1803.5.3 of the 2019 California Building Code (2019 CBC). The design of foundations and slabs on-ground should therefore be performed in accordance with the procedures outlined in Sections 1808.6.1 and 1808.6.2 of the 2019 CBC. General Briefly, Section 1808.6.1 of the 2019 CBC requires that foundations placed on or within the active zone of expansive soils shall be designed to resist differential volume changes and to prevent structural damage to the supported structure. Section 1808.6.2 of the 2019 CBC requires that non-prestressed slabs on-grade or mat foundations constructed on expansive soils be designed in accordance with WRI/CRSI Design of Slab- on-Ground Foundations. The 2019 CBC also requires that post-tensioned slabs on-grade or mat foundations placed on expansive soils be designed in accordance with PTI DC10.5-12, “Standard Requirements for Design of Shallow Post-Tensioned Concrete Foundation on Expansive Soils” with the provision that the analyses used to determination of moments, shears and deflections are performed accordingly. It should be noted that, under certain conditions, the 2019 CBC allows for alternative, rational methods of analysis and design of such slabs provided that these methods account for soil-structure interaction, the deformed shape of the soil support, plate or stiffened plate action of the slab, as well as both center lift and edge lift conditions. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 25 The design and construction guidelines that follow are based on the above soil conditions and may be considered for reducing the effects of variability in fabric, composition and, therefore, the detrimental behavior of the site soils such as excessive short- and long-term total and differential heave and settlement. These guidelines have been developed on the basis of the previous experience of this firm on projects with similar soil conditions. Although construction performed in accordance with these guidelines has been found to reduce post-construction movement and/or distress, they generally do not positively eliminate all potential effects of variability in soils characteristics and future settlement. It should also be noted that the suggestions for dimension and reinforcement provided herein are performance-based and intended only as preliminary guidelines to achieve adequate performance under the anticipated soil conditions. However, they should not be construed as replacement for structural engineering analyses, experience and judgment. The project structural engineer, architect and/or civil engineer should make appropriate adjustments to slab and footing dimensions, and reinforcement type, size and spacing to account for internal concrete forces (e.g., thermal, shrinkage and expansion) as well as external forces (e.g., applied loads) as deemed necessary. Consideration should also be given to minimum design criteria as dictated by local building code requirements. Conventional Slab on-Grade System As stated above, onsite soils should be considered expansive per Section 1803.5.3 of the 2019 CBC. For soils that are considered expansive, Section 1808.6.2 of the 2019 CBC specifies that non-prestressed slab- on-grade foundations constructed on expansive materials should be designed in accordance with the latest edition of the Wire Reinforcement Institute (WRI) publication “Design of Slab-on-Ground Foundations”. The design procedures outlined in the WRI publication are based on the weighted plasticity index of the various soil layers existing within the upper 15 feet of the building site. Based on the recent laboratory testing by our firm, a weighted plasticity index of 15 can be assumed for the subject site. The WRI publication states that the weighted plasticity index of each building site should be modified (multiplied) by correction factors that compensate for the effects of sloping ground and the unconfined compressive strength of the supporting soil or bedrock materials. Since the building(s) will be constructed on level building pads, and in consideration of the estimated unconfined compressive strength of the onsite soils, it is recommended that the weighted plasticity index, as provided herein, be multiplied by a factor of 1.2 in order to determine the value of the effective plasticity index (per Figure 9 of the WRI publication). In summary, it is recommended that an effective plasticity index of 18 be utilized by the PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 26 project structural engineer to design slabs on-ground with an interior grade beam system in accordance with the WRI publication. Footings 1. Exterior continuous footings supporting one- and two-story structures should be founded at a minimum depth of 18 inches below the lowest adjacent final grade. Interior continuous footings may be founded at a minimum depth of 12 inches below the top of the adjacent finish floor slabs. 2. In accordance with Table 1809.7 of 2019 CBC for light-frame construction, all continuous footings should have minimum widths of 12 inches for one- and two-story construction. We recommend all continuous footings should be reinforced with a minimum of four No. 4 bars, two top and two bottom. 3. A minimum 12-inch-wide grade beam founded at the same depth as adjacent footings should be provided across the garage entrances or similar openings (such as large doors or bay windows). The grade beam should be reinforced in a similar manner as provided above. 4. Interior isolated pad footings, if required, should be a minimum of 24 inches square and founded at a minimum depth of 12 inches below the bottoms of the adjacent floor slabs. Pad footings should be reinforced with No. 5 bars spaced a maximum of 12 inches on centers, both ways, placed near the bottoms of the footings. Isolated pad footings should be connected to the floor slab, or grade beam to maintain structural connectivity to the rest of the foundation system. 5. Exterior isolated pad footings intended for support of roof overhangs such as second-story decks, patio covers and similar construction should be a minimum of 24 inches square, and founded at a minimum depth of 18 inches below the lowest adjacent final grade. The pad footings should be reinforced with No. 5 bars spaced a maximum of 12 inches on centers, both ways, placed near the bottoms of the footings. Exterior isolated pad footings may need to be connected to adjacent pad and/or continuous footings via tie beams at the discretion of the project structural engineer. 6. The spacing and layout of the interior concrete grade beam system required below floor slabs should be determined by the project architect or structural engineer in accordance with the WRI publication using the effective plasticity index value provided previously. 7. The minimum footing dimensions and reinforcement recommended herein may be modified (increased or decreased subject to the constraints of Chapter 18 of the 2019 CBC) by the structural engineer responsible for foundation design based on his/her calculations and engineering experience and judgment. Building Floor Slabs 1. Concrete floor slabs should be a minimum 4 inches thick and reinforced with a minimum No. 4 bars spaced a maximum of 15 inches on centers, both ways. All slab reinforcement should be supported on concrete chairs or brick to ensure the desired placement near mid-depth. Slab dimension, reinforcement type, size and spacing need to account for internal concrete forces (e.g., thermal, shrinkage and expansion) as well as external forces (e.g., applied loads), as deemed necessary. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 27 2. Living area concrete floor slabs and areas to receive moisture sensitive floor covering should be underlain with a moisture vapor retarder consisting of a minimum 10-mil-thick polyethylene or polyolefin membrane that meets the minimum requirements of ASTM E96 and ASTM E1745 for vapor retarders (such as Husky Yellow Guard®, Stego® Wrap, or equivalent). All laps within the membrane should be sealed, and at least 2 inches of clean sand should be placed over the membrane to promote uniform curing of the concrete. To reduce the potential for punctures, the membrane should be placed on a pad surface that has been graded smooth without any sharp protrusions. If a smooth surface cannot be achieved by grading, consideration should be given to lowering the pad finished grade an additional inch and then placing a 1-inch-thick leveling course of sand across the pad surface prior to the placement of the membrane. At the present time, some slab designers, geotechnical professionals and concrete experts view the sand layer below the slab (blotting sand) as a place for entrapment of excess moisture that could adversely impact moisture-sensitive floor coverings. As a preventive measure, the potential for moisture intrusion into the concrete slab could be reduced if the concrete is placed directly on the vapor retarder. However, if this sand layer is omitted, appropriate curing methods must be implemented to ensure that the concrete slab cures uniformly. A qualified materials engineer with experience in slab design and construction should provide recommendations for alternative methods of curing and supervise the construction process to ensure uniform slab curing. Additional steps would also need to be taken to prevent puncturing of the vapor retarder during concrete placement. 3. Garage floor slabs should be a minimum 4 inches thick and reinforced in a similar manner as living area floor slabs. Garage slabs should also be poured separately from adjacent wall footings with a positive separation maintained using ¾-inch-minimum felt expansion joint material. To control the propagation of shrinkage cracks, garage floor slabs should be quartered with weakened plane joints . Consideration should be given to placement of a moisture vapor retarder below the garage slab, similar to that provided in Item 2 above, should the garage slab be overlain with moisture sensitive floor covering. 4. Prior to placing concrete, the subgrade soils below living area floor slabs should be prewatered to achieve a moisture content that is at least 1.2 times the optimum moisture content. This moisture should penetrate to a depth of approximately 12 inches into the subgrade. 5. The minimum dimensions and reinforcement recommended herein for building floor slabs may be modified (increased or decreased) by the structural engineer responsible for foundation design based on his/her calculations and engineering experience and judgment. Footing Observations All footing trenches should be observed by a representative of the project geotechnical consultant to document that they have been excavated into competent bearing soils prior to the placement of forms, reinforcement or concrete. The excavations should be trimmed neat, level and square. All loose, sloughed or moisture-softened soils and/or any construction debris should be removed prior to the placing of concrete. Excavated soils derived from footing and/or utility trenches should not be placed in building slab- on-grade areas or exterior concrete flatwork areas unless the soils are compacted to at least 90 percent of maximum dry density. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 28 General Corrosivity Screening As a screening level study, limited chemical and electrical tests were performed on representative samples of onsite soils to identify potential corrosive characteristics of these soils. The following sections present the test results and an interpretation of current codes and guidelines that are commonly used in our industry as they relate to the adverse impact of chemical contents and electrical resistance of the site soils on various components of the proposed structures in contact with site soils. A variety of test methods are available to quantify corrosive potential of soils for various elements of construction materials. Depending on the test procedures adopted, characteristics of the leachate that is used to extract the target chemicals from the soils and the test equipment; the results can vary appreciably for different test methods in addition to those caused by variability in soil composition. The testing procedures referred to herein are considered to be typical for our industry and have been adopted and/or approved by many public or private agencies. In drawing conclusions from the results of our chemical and electrical laboratory testing and providing mitigation guidelines to reduce the detrimental impact of corrosive site soils on various components of the structure in contact with site soils, heavy references were made to 2019 California Building Code (2019 CBC) and American Concrete Institute publication (2014 Building Code Requirements for Structural Concrete, ACI 318-14). Where relevant information was not available in these codes, references were made to guidelines developed by California Department of Transportation (Caltrans), Post-Tensioning Institute (PTI DC10.5-12) and other reputable institutions and/or publications. Specifically, the reference to Caltrans approach were made because their risk management protocol for highway bridges are considered comparable to those for residential or commercial structures and that Post Tensioning Institute (PTI), in part, accepts and uses Caltrans’ relevant corrosivity criteria for post-tensioned slabs on-grade. It should be noted that Petra does not practice corrosion engineering; therefore, the test results, opinion and engineering judgment provided herein should be considered as general guidelines only. Additional analyses would be warranted, especially, for cases where buried metallic building materials (such as copper and cast or ductile iron pipes) in contact with site soils are planned for the project . In many cases, the project geotechnical engineer may not be informed of these choices. Therefore, for conditions where such elements are considered, we recommend that other, relevant project design professionals (e.g., the architect, landscape architect, civil and/or structural engineer) also consider recommending a qualified corrosion engineer to conduct additional sampling and testing of near-surface soils during the final stages of site grading to provide a complete assessment of soil corrosivity. Recommendations to mitigate the detrimental effects of corrosive soils on buried metallic and other building materials that may be exposed to corrosive soils should be provided by the corrosion engineer as deemed appropriate. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 29 Concrete in Contact with Site Soils Soils containing soluble sulfates beyond certain threshold levels as well as acidic soils are considered to be detrimental to long-term integrity of concrete placed in contact with such soils. For the purpose of this study, soluble sulfates (SO42-) concentration in soils determined in accordance with California Test Method No. 417. Soil acidity, as indicated by hydrogen-ion concentration (pH), was determined in accordance with California Test Method No. 643. The soil acid severity rating is adopted from The United States Department of Agriculture, Natural Resources Conservation Service classification. Article 1904.1 of Section 1904 of the 2019 CBC indicates that structural concrete shall conform to the durability requirements of ACI 318. Concrete durability is impacted by exposure to water soluble chemicals and its resistance to fluid penetration. Section 19.3 of Chapter 19 of ACI 318-14 provides guidelines for assigning exposure categories and classes for various conditions. Exposure Category S, which is subdivided to four Exposure Classes of S0, S1, S2 and S3, applies to concrete in contact with soil or water containing deleterious amounts of water soluble ions. The results of our limited in-house laboratory tests indicate that on-site soils contain a water-soluble sulfate content that range from 0.0066 percent by weight. Based on Table 19.3.1.1 of ACI 318-14, the Exposure Class S0 is appropriate for onsite soils. For this exposure class, Table 19.3.2.1 of ACI 318-14 provides that no restriction for cement type or maximum water-cement ratio for the fresh concrete would be required. Further, this table indicates that the concrete minimum unconfined strength should not be less than 2,500 psi. The results of limited in-house testing of representative samples indicate that soils within the subject site are moderately alkaline with respect to pH (a pH of 7.9). Based on this finding and according to Table 8.22.2 of Caltrans’ 2003 Bridge Design Specifications (2003 BDS) requirements (which consider the combined effects of soluble sulfates and soil pH), a commercially available Type II Modified cement may be used. The guidelines provided herein should be evaluated and confirmed, or modified, in its entirety by the project structural engineer and the contractor responsible for concrete placement for structural concrete used in exterior and interior footings, interior slabs on-ground, garage slabs, walls foundation and concrete exposed to weather such as driveways, patios, porches, walkways, ramps, steps, curbs, etc. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 30 Metals Encased in Concrete Soils containing a soluble chloride concentration beyond a certain threshold level are considered corrosive to metallic elements such as reinforcement bars, tendons, cables, bolts, anchors, etc. that are encased in concrete that, in turn, is in contact with such soils. For the purpose of this study, soluble chlorides (Cl) in soils were determined in accordance with California Test Method No. 422. As stated Earlier, Article 1904.1 of Section 1904 of the 2019 CBC indicates that structural concrete shall conform to the durability requirements of ACI 318. Concrete durability is impacted by exposure to water soluble chemicals and its resistance to fluid penetration. Section 19.3 of Chapter 19 of ACI 318-14 provides guidelines for assigning exposure categories and classes for various conditions. Exposure Category C, which is subdivided to three Exposure Classes of C0, C1, and C2, applies to nonprestressed and prestressed concrete exposed to conditions that require additional protection against corrosion of reinforcement. According to Table 19.3.1.1 of ACI 318-14, the Exposure Class C0 is appropriate for reinforced concrete that remains dry or protected from moisture. Similarly, the Exposure Class C1 is appropriate for reinforced concrete that is exposed to moisture but not to external sources of chlorides. And, lastly, the Exposure Class C2 is appropriate for reinforced concrete that is exposed to moisture and external sources of chlorides as “deicing chemicals, salt, brackish water, seawater, or spray from these sources”. Based on our understanding of the project, it is our professional opinion that the Exposure Class C1 is appropriate for a majority of reinforced concrete, to be placed at the site, that are in contact with site soils . It should be noted, however, that the Exposure Class C2 is more appropriate for reinforced concrete that is planned for pool walls and decking, should such features be considered for the project. The results of our limited laboratory tests performed indicate that onsite soils contain a water-soluble chloride concentration that range from 84 parts per million (ppm). No maximum water/cement ratio for the fresh concrete is prescribed by ACI 318 for Exposure Class C1 condition. Table 19.3.2.1 of ACI 318-14 indicates that concrete minimum unconfined compressive strength, f’c, should not be less than 2,500 psi. For Exposure Class C2 condition, Table 19.3.2.1 of ACI 318-14 requires that the maximum water/cement ratio of the fresh concrete should not exceed 0.40 and concrete minimum unconfined compressive strength, f’c, should not be less than 5,000 psi. The guidelines provided herein should be evaluated and confirmed, or modified, in its entirety by the project structural engineer for reinforced concrete placement for structural concrete used in exterior and interior footings, interior slabs on-ground, garage slabs, walls foundation and concrete exposed to weather such as driveways, patios, porches, walkways, ramps, steps, curbs, etc. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 31 It should be noted that another source of elevated chloride-ion concentration can be the chloride content of water that is used to prepare the fresh concrete at the plant. The protection against high chloride concentration in fresh concrete should, therefore, be provided by concrete suppliers for the project. Metallic Elements in Contact with Site Soils Elevated concentrations of soluble salts in soils tend to induce low level electrical currents in metallic objects in contact with such soils. This process promotes metal corrosion and can lead to distress to building metallic components that are in contact with site soils. The minimum electrical resistivity measurement provides a simple indication of relative concentration of soluble salts in the soil and, therefore, is widely used to estimate soil corrosivity with regard to metals. For the purpose of this investigation, the minimum resistivity in soils is measured in accordance with California Test Method No. 643. The soil corrosion severity rating is adopted from the Handbook of Corrosion Engineering by Pierre R. Roberge. The minimum electrical resistivity for onsite soils was found to be 2,200 ohm-cm based on limited testing. The result indicates that on-site soils are Highly Corrosive to ferrous metals and copper. As such, any ferrous metal or copper components of the subject buildings (such as cast iron or ductile iron piping, copper tubing, etc.) that are expected to be placed in direct contact with site soils should be protected against detrimental effects of corrosive soils. Such protection could include the use of galvanized tubing, coated pipes, wrapping or encasing these metallic objects in special protection wrappings or conduits or devising a cathodic protection system. It should be noted that at this time Petra is not aware of any plans to incorporate such items for the proposed buildings. Should such elements be considered for these building, we recommend that a corrosion engineer to be consulted to provide appropriate recommendations for long term protection of metallic elements in contact with site soils. Masonry Block Walls Footings for free-standing masonry block walls and other rigid structures should be designed and reinforced utilizing the criteria recommended for conventional building foundations. Where existing surface soils are not removed and re-compacted as recommended herein, the footings should be extended through these loose surface soils and founded in underlying competent materials. Positive separations in walls should also be provided at corners and at horizontal spacing of approximately 25 feet to permit relative movement. The separations should be provided in the blocks and not extend through the footings . The footings should be poured monolithically with continuous rebars to serve as effective “grade beams” below the walls. However, where remedial grading cannot be performed due to site constraints, a reduced bearing value of 1,200 pounds per square foot should be used for 12-inch-wide continuous footings founded at a minimum PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 32 depth of 12 inches below the lowest adjacent final grade. No increase in bearing value may be used for wider or deeper footings for this condition. The recommended allowable bearing value includes both dead and live loads, and may be increased by one-third for short duration wind and seismic forces. In addition, a reduced passive earth pressure of 175 pounds per square foot per foot of depth, to a maximum value of 1,750 pounds per square foot, should be used to resist lateral loads. A coefficient of friction of 0.40 times the dead load forces may still be used between concrete and the supporting soils to determine lateral sliding resistance. The above values may be combined without reduction provided the lateral sliding resistance does not exceed one-half the dead load. An increase of one-third of the above values may also be used when designing for short duration wind or seismic forces. Exterior Concrete Flatwork Soils with Expansion Indices in the Range of 21 to 45 General Near-surface compacted fill soils within the site are variable in fines content and expansion behavior with an expectation for the majority of these soils to exhibit an Expansion Index, EI, in the range of mid-20s to mid- to high 40s. For this reason, we recommend that additional testing of subgrade soils be performed at the completion of precise grading in order to provide specific recommendations for all exterior concrete flatwork. However, owing to typical project scheduling constraints, it may not be feasible to collect additional samples of subgrade soils for testing to verify their expansion characteristics in a timely manner; i.e., immediately prior to pouring concrete. As such, we recommend that all exterior concrete flatwork such as sidewalks, patio slabs, large decorative slabs, concrete subslabs that will be covered with decorative pavers, private and/or public vehicular parking, driveways and/or access roads within and adjacent to the site be designed by the project architect, civil and/or structural engineer with consideration given to mitigating the potential cracking, curling, uplift, etc. that can develop in soils exhibiting expansion index values that fall in the upper ranges of the values provided above. The guidelines that follow should be considered as minimums and are subject to review and revision by the project architect, civil engineer, structural engineer and/or landscape consultant as deemed appropriate . If sufficient time will be allowed in the project schedule for verification sampling and testing prior to the concrete pour, the test results may dictate that a somewhat less conservative design could be used. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 33 Subgrade Preparation Compaction To reduce the potential for distress to concrete flatwork, the subgrade soils below concrete flatwork areas to a minimum depth of 12 inches (or deeper, as either prescribed elsewhere in this report or determined in the field) should be moisture conditioned to at least equal to, or slightly greater than, the optimum moisture content and then compacted to a minimum relative compaction of 90 percent. Where concrete public roads, concrete segments of roads and/or concrete access driveways and heavy recreational vehicles parking are proposed, the upper 6 inches of subgrade soil should be compacted to a minimum 95 percent relative compaction. Pre-Moistening As a further measure to reduce the potential for concrete flatwork distress, subgrade soils should be thoroughly moistened prior to placing concrete. The moisture content of the soils should be at least 1.2 times the optimum moisture content and penetrate to a minimum depth of 12 inches into the subgrade. Pre- watering of the soils is intended to promote uniform curing of the concrete, reduce the development of shrinkage cracks and reduce the potential for differential expansion pressure on freshly poured flatwork. A representative of the project geotechnical consultant should observe and verify the density and moisture content of the soils, and the depth of moisture penetration prior to pouring concrete. Thickness and Joint Spacing To reduce the potential of unsightly cracking, concrete walkways, patio-type slabs, large decorative slabs and concrete subslabs to be covered with decorative pavers should be at least 4 inches thick and provided with construction joints or expansion joints every 6 feet or less. Private driveways that will be designed for the use of passenger cars for access to private garages should also be at least 4 inches thick and provided with construction joints or expansion joints every 10 feet or less. Concrete pavement that will be designed based on an unlimited number of applications of an 18-kip single-axle load in public access areas, segments of road that will be paved with concrete (such as bus stops and cross-walks) or access roads and driveways, which serve multiple residential units or garages, that will be subject to heavy truck loadings and recreational vehicles parking should have a minimum thickness of 5 inches and be provided with control joints spaced at maximum 10-foot intervals. A modulus of subgrade reaction of 125 pounds per cubic foot may be used for design of the public and access roads. PEPPERWOOD PLACE LP June 14, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 34 Reinforcement All concrete flatwork having their largest plan-view panel dimensions exceeding 10 feet should be reinforced with a minimum of No. 3 bars spaced 15 inches for 4-inch-thick slabs and No. 4 bars spaced 21 inches for 5-inch-thick slabs on centers, both ways. The reinforcement should be properly positioned near the middle of the slabs. All foot and equipment traffic on the reinforcement should be avoided or reduced to a minimum. The reinforcement recommendations provided herein are intended as a guideline to achieve adequate performance for anticipated soil conditions. As such, this guideline may not satisfy certain acceptable approaches, e.g. the area of reinforcement to be equal to or greater that 0.2 percent of the area of concrete. The project architect, civil and/or structural engineer should make appropriate adjustments in reinforcement type, size and spacing to account for concrete internal (e.g., shrinkage and thermal) and external (e.g., applied loads) forces as deemed necessary. Edge Beams (Optional) Where the outer edges of concrete flatwork are to be bordered by landscaping, it is recommended that consideration be given to the use of edge beams (thickened edges) to prevent excessive infiltration and accumulation of water under the slabs. Edge beams, if used, should be 6 to 8 inches wide, extend 8 inches below the tops of the finish slab surfaces. Edge beams are not mandatory; however, their inclusion in flatwork construction adjacent to landscaped areas is intended to reduce the potential for vertical and horizontal movement and subsequent cracking of the flatwork related to uplift forces that can develop in expansive soils. Drainage Drainage from patios and other flatwork areas should be directed to local area drains and/or graded earth swales designed to carry runoff water to the adjacent streets or other approved drainage structures. The concrete flatwork should be sloped at a minimum gradient of one percent, or as prescribed by project civil engineer or local codes, away from building foundations, retaining walls, masonry garden walls and slope areas. Tree Wells Tree wells are not recommended in concrete flatwork areas because they typically introduce excessive water into the subgrade soils and allow root invasion, both of which can cause heaving and cracking of the flatwork.

The relatively undisturbed samples were obtained using a 3-inch, outside-diameter, modified California split-spoon soil sampler lined with 1-inch-high brass rings. The driven ring samples were placed in sealed containers and transported to our laboratory located at 1251 W. Pomona Road, Unit #103, Corona, CA 92882, for testing. Our laboratory testing capabilities include Soil Classifications, Moisture Content and In-Situ Moisture Content and Dry Unit Weight, Organic Content, Laboratory Maximum Dry Unit Weight and Optimum Moisture Content, Expansion Index, Corrosivity Screening (Soluble Sulfate and Chloride Content, pH, Resistivity), Atterberg Limits, Grain Size Distribution, Direct Shear, Consolidation and Permeability; all in accordance with the latest procedures of American Society for Testing and Materials (ASTM) and California Department of Transportation (Caltrans). To evaluate the engineering properties of site soils, laboratory testing was performed on selected samples of soil considered representative of those encountered. Appropriate tests were assigned by the project engineer and geologist based on project plans and specifications including the level of anticipated loads, when available, and subsurface stratigraphy. Test results were reviewed by the laboratory manager and engineer-in-charge of the laboratory or his qualified designee for completeness and accuracy. A description of laboratory test procedures and summaries of the test data are presented in the following pages.

Pomona Road, Unit 103, Corona, CA, 92882 J.N. 17-440 Soil Classification Soil materials encountered within the property were classified and described in accordance with the Unified Soil Classification System and in general accordance with the current version of Test Method ASTM D 2488 . The assigned group symbols are presented in the exploration logs, Appendix A. Moisture Content and In Situ Moisture Content and Dry Unit Weight Moisture content of selected bulk samples and in- place moisture content and dry unit weight of selected, relatively undisturbed soil samples were determined in accordance with the current version of Test Method ASTM D 2435 and Test Method ASTM D 2216, respectively. Test data are presented in the exploration logs, Appendix A. Laboratory Maximum Dry Unit Weight and Optimum Moisture Content The maximum dry unit weight and optimum moisture content of the on-site soils were determined for selected bulk samples in accordance with current version of Method A of ASTM D 1557. The results of these tests are presented on Plates B-1 and B-2. Expansion Index Expansion index tests were performed on selected bulk samples of the on-site soils in accordance with the current version of Test Method ASTM D 4829. The test results are presented on Plate B-1. Atterberg Limits The Atterberg limits (liquid limit and plastic limit) were determined for selected bulk samples of representative materials in accordance with the current version of Test Method ASTM D 4318 . The results of these tests are included on Plate B-3. Corrosivity Screening Chemical and electrical analyses were performed on selected bulk samples of onsite soils to determine their soluble sulfate content, chloride content, pH (acidity) and minimum electrical resistivity. These tests were performed in accordance with the current versions of California Test Method Nos. CTM 417 (sulfate), CTM 422 (chloride), and CTM 643 (pH and resistivity) respectively. The results of these tests are included on Plate B-1. Percent Passing No. 200 Sieve Selected samples were run through a number 200 sieve in general accordance with the current version of Test Method ASTM D 1140. The results of these tests are included on Plate B-1. Direct Shear The Coulomb shear strength parameters, i.e., angle of internal friction and cohesion, were determined for selected, relatively undisturbed and/or reconstituted-bulk samples of onsite soil. This test was performed in general accordance with the current version of Test Method ASTM D 3080. Three specimens were prepared for each test. The test specimens were inundated and then sheared under various normal loads at a constant strain rate of 0.005 inch per minute. The results of the direct shear test are graphically presented on Plates B-4. Consolidation Volume change (settlement or heave) characteristics of select undisturbed soils were determined by one-dimensional consolidation tests. These tests were performed in general accordance with the current version of the Test Method ASTM D 2435. Additionally, heave or hydro-consolidation tests were performed in general accordance with the current version of Test Method ASTM D 4546, or ASTM D 5333 respectively. Axial loads were applied in several increments to laterally restrained 1-inch-high samples. The resulting deformations were recorded at selected time intervals. The test samples were inundated at the approximate in-situ and/or anticipated design overburden pressure in order to evaluate the effect of an increase in moisture content, e.g., hydro-consolidation potential or heave. Results of these tests are graphically presented on Plates B-5 through B-7. _____________________________________________________________________________________________________________________________________ PETRA GEOSCIENCES, INC Laboratory Address: 1251 W.

To do this the software requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < Ic < 3.0) and a rate of change of Ic. Transitions typically occur when the rate of change of Ic is fast (i.e. delta Ic is small). The SBTn plot below, displays in red the detected transition layers based on the parameters listed below the graphs.

To do this the software requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < Ic < 3.0) and a rate of change of Ic. Transitions typically occur when the rate of change of Ic is fast (i.e. delta Ic is small). The SBTn plot below, displays in red the detected transition layers based on the parameters listed below the graphs.

To do this the software requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < Ic < 3.0) and a rate of change of Ic. Transitions typically occur when the rate of change of Ic is fast (i.e. delta Ic is small).

To do this the software requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < Ic < 3.0) and a rate of change of Ic.

M. Idriss, San Diego, CA CLiq v.3.0.3.4 - CPT Liquefaction Assessment Software 43 Liquefaction Potential Index (LPI) calculation procedure Graphical presentation of the LPI calculation procedure Calculation of the Liquefaction Potential Index (LPI) is used to interpret the liquefaction assessment calculations in terms of severity over depth. The calculation procedure is based on the methology developed by Iwasaki (1982) and is adopted by AFPS. To estimate the severity of liquefaction extent at a given site, LPI is calculated based on the following equation: LPI = where: FL = 1 - F.S. when F.S. less than 1 FL = 0 when F.S. greater than 1 z depth of measurment in meters Values of LPI range between zero (0) when no test point is characterized as liquefiable and 100 when all points are characterized as susceptible to liquefaction. Iwasaki proposed four (4) discrete categories based on the numeric value of LPI: ⦁ LPI = 0 : Liquefaction risk is very low ⦁ 0 < LPI <= 5 : Liquefaction risk is low ⦁ 5 < LPI <= 15 : Liquefaction risk is high ⦁ LPI > 15 : Liquefaction risk is very high CLiq v.3.0.3.4 - CPT Liquefaction Assessment Software 44 Shear-Induced Building Settlement (Ds) calculation procedure The shear-induced building settlement (Ds) due to liquefaction below the building can be estimated using the relationship developed by Bray and Macedo (2017): where Ds is in the units of mm, c1= -8.35 and c2= 0.072 for LBS ≤ 16, and c1= -7.48 and c2= 0.014 otherwise. Q is the building contact pressure in units of kPa, HL is the cumulative thickness of the liquefiable layers in the units of m, B is the building width in the units of m, CAVdp is a standardized version of the cumulative absolute velocity in the units of g-s, Sa1 is 5%-damped pseudo-acceleration response spectral value at a period of 1 s in the units of g, and ε is a normal random variable with zero mean and 0.50 standard deviation in Ln units. The liquefaction-induced building settlement index (LBS) is: where z (m) is the depth measured from the ground surface > 0, W is a foundation-weighting factor wherein W = 0.0 for z less than Df, which is the embedment depth of the foundation, and W = 1.0 otherwise. The shear strain parameter (ε_shear) is the liquefaction-induced free-field shear strain (in %) estimated using Zhang et al. (2004). It is calculated based on the estimated Dr of the liquefied soil layer and the calculated safety factor against liquefaction triggering (FSL).

(Petra) is the geotechnical consultant. No deviation from these specifications will be allowed, except where specifically superseded in the preliminary geology and soils report, or in other written communication signed by the Soils Engineer and Engineering Geologist of record (Geotechnical Consultant). I. GENERAL A. The Geotechnical Consultant is the Owner's or Builder's representative on the project. For the purpose of these specifications, participation by the Geotechnical Consultant includes that observation performed by any person or persons employed by, and responsible to, the licensed Soils Engineer and Engineering Geologist signing the soils report. B. The contractor should prepare and submit to the Owner and Geotechnical Consultant a work plan that indicates the sequence of earthwork grading, the number of "spreads" and the estimated quantities of daily earthwork to be performed prior to the commencement of grading. This work plan should be reviewed by the Geotechnical Consultant to schedule personnel to perform the appropriate level of observation, mapping, and compaction testing as necessary. C. All clearing, site preparation, or earthwork performed on the project shall be conducted by the Contractor in accordance with the recommendations presented in the geotechnical report and under the observation of the Geotechnical Consultant. D. It is the Contractor's responsibility to prepare the ground surface to receive the fills to the satisfaction of the Geotechnical Consultant and to place, spread, mix, water, and compact the fill in accordance with the specifications of the Geotechnical Consultant. The Contractor shall also remove all material considered unsatisfactory by the Geotechnical Consultant. E. It is the Contractor's responsibility to have suitable and sufficient compaction equipment on the job site to handle the amount of fill being placed. If necessary, excavation equipment will be shut down to permit completion of compaction to project specifications. Sufficient watering apparatus will also be provided by the Contractor, with due consideration for the fill material, rate of placement, and time of year. F. After completion of grading a report will be submitted by the Geotechnical Consultant. II. SITE PREPARATION A. Clearing and Grubbing 1. All vegetation such as trees, brush, grass, roots, and deleterious material shall be disposed of offsite. This removal shall be concluded prior to placing fill. 2. Any underground structures such as cesspools, cisterns, mining shafts, tunnels, septic tanks, wells, pipe lines, etc., are to be removed or treated in a manner prescribed by the Geotechnical Consultant. STANDARD GRADING SPECIFICATIONS Page 2 III. FILL AREA PREPARATION A. Remedial Removals/Overexcavations 1. Remedial removals, as well as overexcavation for remedial purposes, shall be evaluated by the Geotechnical Consultant. Remedial removal depths presented in the geotechnical report and shown on the geotechnical plans are estimates only. The actual extent of removal should be determined by the Geotechnical Consultant based on the conditions exposed during grading. All soft, loose, dry, saturated, spongy, organic-rich, highly fractured or otherwise unsuitable ground shall be overexcavated to competent ground as determined by the Geotechnical Consultant. 2. Soil, alluvium, or bedrock materials determined by the Soils Engineer as being unsuitable for placement in compacted fills shall be removed from the site. Any material incorporated as a part of a compacted fill must be approved by the Geotechnical Consultant. 3. Should potentially hazardous materials be encountered, the Contractor should stop work in the affected area. An environmental consultant specializing in hazardous materials should be notified immediately for evaluation and handling of these materials prior to continuing work in the affected area. B. Evaluation/Acceptance of Fill Areas All areas to receive fill, including removal and processed areas, key bottoms, and benches, shall be observed, mapped, elevations recorded, and/or tested prior to being accepted by the Geotechnical Consultant as suitable to receive fill. The contractor shall obtain a written acceptance from the Geotechnical Consultant prior to fill placement. A licensed surveyor shall provide sufficient survey control for determining locations and elevations of processed areas, keys, and benches. C. Processing After the ground surface to receive fill has been declared satisfactory for support of fill by the Geotechnical Consultant, it shall be scarified to a minimum depth of 6 inches and until the ground surface is uniform and free from ruts, hollows, hummocks, or other uneven features which may prevent uniform compaction. The scarified ground surface shall then be brought to optimum moisture, mixed as required, and compacted to a minimum relative compaction of 90 percent. D. Subdrains Subdrainage devices shall be constructed in compliance with the ordinances of the controlling governmental agency, and/or with the recommendations of the Geotechnical Consultant. (Typical Canyon Subdrain details are given on Plate SG-1). E. Cut/Fill & Deep Fill/Shallow Fill Transitions In order to provide uniform bearing conditions in cut/fill and deep fill/shallow fill transition lots, the cut and shallow fill portions of the lot should be overexcavated to the depths and the horizontal limits discussed in the approved geotechnical report and replaced with compacted fill. (Typical details are given on Plate SG-7.) STANDARD GRADING SPECIFICATIONS Page 3 IV. COMPACTED FILL MATERIAL A. General Materials excavated on the property may be utilized in the fill, provided each material has been determined to be suitable by the Geotechnical Consultant. Material to be used for fill shall be essentially free of organic material and other deleterious substances. Roots, tree branches, and other matter missed during clearing shall be removed from the fill as recommended by the Geotechnical Consultant. Material that is spongy, subject to decay, or otherwise considered unsuitable shall not be used in the compacted fill. Soils of poor quality, such as those with unacceptable gradation, high expansion potential, or low strength shall be placed in areas acceptable to the Geotechnical Consultant or mixed with other soils to achieve satisfactory fill material. B. Oversize Materials Oversize material defined as rock, or other irreducible material with a maximum dimension greater than 12 inches in diameter, shall be taken offsite or placed in accordance with the recommendations of the Geotechnical Consultant in areas designated as suitable for rock disposal (Typical details for Rock Disposal are given on Plate SG-4). Rock fragments less than 12 inches in diameter may be utilized in the fill provided, they are not nested or placed in concentrated pockets; they are surrounded by compacted fine grained soil material and the distribution of rocks is approved by the Geotechnical Consultant. C. Laboratory Testing Representative samples of materials to be utilized as compacted fill shall be analyzed by the labora- tory of the Geotechnical Consultant to determine their physical properties. If any material other than that previously tested is encountered during grading, the appropriate analysis of this material shall be conducted by the Geotechnical Consultant as soon as possible. D. Import If importing of fill material is required for grading, proposed import material should meet the requirements of the previous section. The import source shall be given to the Geotechnical Consultant at least 2 working days prior to importing so that appropriate tests can be performed and its suitability determined. V. FILL PLACEMENT AND COMPACTION A. Fill Layers Material used in the compacting process shall be evenly spread, watered, processed, and compacted in thin lifts not to exceed 6 inches in thickness to obtain a uniformly dense layer. The fill shall be placed and compacted on a horizontal plane, unless otherwise approved by the Geotechnical Consultant. STANDARD GRADING SPECIFICATIONS Page 4 B. Moisture Conditioning Fill soils shall be watered, dried back, blended, and/or mixed, as necessary to attain a relatively uniform moisture content at or slightly above optimum moisture content. C. Compaction Each layer shall be compacted to 90 percent of the maximum density in compliance with the testing method specified by the controlling governmental agency. (In general, ASTM D 1557-02, will be used.) If compaction to a lesser percentage is authorized by the controlling governmental agency because of a specific land use or expansive soils condition, the area to received fill compacted to less than 90 percent shall either be delineated on the grading plan or appropriate reference made to the area in the soils report. D. Failing Areas If the moisture content or relative density varies from that required by the Geotechnical Consultant, the Contractor shall rework the fill until it is approved by the Geotechnical Consultant. E. Benching All fills shall be keyed and benched through all topsoil, colluvium, alluvium or creep material, into sound bedrock or firm material where the slope receiving fill exceeds a ratio of 5 horizontal to 1 vertical, in accordance with the recommendations of the Geotechnical Consultant. VI. SLOPES A. Fill Slopes The contractor will be required to obtain a minimum relative compaction of 90 percent out to the finish slope face of fill slopes, buttresses, and stabilization fills. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment, or by any other procedure that produces the required compaction. B. Side Hill Fills The key for side hill fills shall be a minimum of 15 feet within bedrock or firm materials, unless otherwise specified in the soils report. (See detail on Plate SG-5.) C. Fill-Over-Cut Slopes Fill-over-cut slopes shall be properly keyed through topsoil, colluvium or creep material into rock or firm materials, and the transition shall be stripped of all soils prior to placing fill. (see detail on Plate SG-6). STANDARD GRADING SPECIFICATIONS Page 5 D. Landscaping All fill slopes should be planted or protected from erosion by other methods specified in the soils report. E. Cut Slopes 1. The Geotechnical Consultant should observe all cut slopes at vertical intervals not exceeding 10 feet. 2. If any conditions not anticipated in the preliminary report such as perched water, seepage, lenticular or confined strata of a potentially adverse nature, unfavorably inclined bedding, joints or fault planes are encountered during grading, these conditions shall be evaluated by the Geotechnical Consultant, and recommendations shall be made to treat these problems (Typical details for stabilization of a portion of a cut slope are given in Plates SG-2 and SG- 3.). 3. Cut slopes that face in the same direction as the prevailing drainage shall be protected from slope wash by a non-erodible interceptor swale placed at the top of the slope. 4. Unless otherwise specified in the soils and geological report, no cut slopes shall be excavated higher or steeper than that allowed by the ordinances of controlling governmental agencies. 5. Drainage terraces shall be constructed in compliance with the ordinances of controlling governmental agencies, or with the recommendations of the Geotechnical Consultant. VII. GRADING OBSERVATION A. General All cleanouts, processed ground to receive fill, key excavations, subdrains, and rock disposals must be observed and approved by the Geotechnical Consultant prior to placing any fill. It shall be the Contractor's responsibility to notify the Geotechnical Consultant when such areas are ready. B. Compaction Testing Observation of the fill placement shall be provided by the Geotechnical Consultant during the progress of grading. Location and frequency of tests shall be at the Consultants discretion based on field conditions encountered. Compaction test locations will not necessarily be selected on a random basis. Test locations may be selected to verify adequacy of compaction levels in areas that are judged to be susceptible to inadequate compaction. C. Frequency of Compaction Testing In general, density tests should be made at intervals not exceeding 2 feet of fill height or every 1000 cubic yards of fill placed. This criteria will vary depending on soil conditions and the size of the job. In any event, an adequate number of field density tests shall be made to verify that the required compaction is being achieved. STANDARD GRADING SPECIFICATIONS Page 6 VIII. CONSTRUCTION CONSIDERATIONS A. Erosion control measures, when necessary, shall be provided by the Contractor during grading and prior to the completion and construction of permanent drainage controls. B. Upon completion of grading and termination of observations by the Geotechnical Consultant, no further filling or excavating, including that necessary for footings, foundations, large tree wells, retaining walls, or other features shall be performed without the approval of the Geotechnical Consultant. C. Care shall be taken by the Contractor during final grading to preserve any berms, drainage terraces, interceptor swales, or other devices of permanent nature on or adjacent to the property.

Western Avenue, City of Anaheim, California; report by Petra Geosciences, Inc., J.N. 17-440, dated June 14, 2021 Dear Ms. McGaughy: This letter has been prepared in response to the subject geotechnical redline comments prepared the City of Anaheim Department of Public Works regarding the proposed residential track development at the subject address. In the interest of clarity, the review items are reiterated herein and are followed by this firm’s responses. A complete copy of the review letter is attached. This review response acts as an addendum to the updated geotechnical report dated June 14, 2021 (Reference No. 2) and should be included in the design and construction of the proposed development. Item No. 2.1.1 General: The report was prepared based on the 2016 CBC. Verify that the findings, conclusions and recommendations in the report remain valid per the current 2019 CBC. The report is being reviewed for entitlement purposes only and will require an update to the current code during the final design phase. Response to Item No. 2.1.1 The t geotechnical report has been updated to the current 2019 California Building Code (2019 CBC). The updated report (Reference No. 2) will be submitted concurrently with this response. PEPPERWOOD PLACE LP June 15, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 2 Item No. 2.1.2 Page 6: The infiltration rate of 0.98 inches/hour: Table 1 indicates the value includes a factor of safety of 2 while Appendix C says no factor of safety. Response to Item No. 2.1.2 We have updated Table 1 in Refence Report No. 2 to clarify that a minimum factor of safety of 2 should be applied to the field rate reported in Table 1. Item No. 2.1.3 Page 11: Confirm that the clay-like material was analyzed for liquefaction potential per CGS Special Publication 117A. Response to Item No. 2.1.3 We have updated the liquefaction analysis in Reference Report No. 2 to conform with the 2019 CBC We have used a modified Ic cutoff value to account for the difference in behavior from Sand Like and Clay Like soils in the updated analysis. This was actually more conservative than applying the clay like behavior to all soils for this project. Item No. 2.1.4 Page 11: The liquefaction assessment references 2013 CBC. Verify that the assessment is still valid per the current CBC. Response to Item No. 2.1.4 The liquefaction assessment within Reference Report No. has been updated to the current 2019 California Building Code (2019 CBC). Item No. 2.1.5 2.1.5 Page 14: Provide recommendations for dewatering if groundwater is expected to be encountered during grading. Response to Item No. 2.1.5 Based on the groundwater elevations measured during our subsurface investigation, groundwater is not expected to be encountered during rough grading of the site and as such, recommendations for the dewatering of groundwater are not considered necessary. PEPPERWOOD PLACE LP June 15, 2021 910 S. Western Avenue / Anaheim J.N. 17-440 Page 3 If groundwater is higher than previously measured and/or local excavations are deeper than anticipated, and if the grading contractor and/or project team plans to implement a groundwater dewatering system, we will provide design recommendations at that time. In lieu of dewatering of groundwater, we may also provide other methods to stabilize local excavation bottoms impacted by groundwater (such as in the area of the pool demolition), such as installing layers of crush rock and/or geofabric to stabilize these bottoms. Item No. 2.1.6 Page 20: Provide discussions if onsite infiltration systems are feasible per OC County Technical Guidance considering the shallow groundwater table at the site. Response to Item No. 2.1.6 The depth to groundwater at the site is discussed on page 4 of the updated report (Reference No. 2). Generally, at the time of our investigation, groundwater levels on the order of 10 feet were measured. Nearby data indicated even shallower levels have been recorded. The design civil engineer should choose BMP’s that allow for more minimal separation to groundwater. Item No. 2.1.7 Page 21: The total settlement appears to be closer to 2 inches than 1½ inches. Response to Item No. 2.1.7 We have updated the settlement analysis to conform with the ground motions from the 2019 CBC requirements. An updated settlement analysis is included in the updated report (Reference No. 2). Item No. 2.1.8 Page 22: The 1st paragraph indicates the soils have very low expansive characteristics while the 2nd paragraph say the soils are classified as “expansive”. Response to Item No. 2.1.8 Expansion Index testing on one selected sample indicated “Very Low” expansion potential . However, as the soils will be reworked during grading, it appears likely that some expansive soils will be encountered near the surface within the building pad. Therefore, we have provided preliminary foundation design parameters that account for soils to be within the “Low” expansion category when classified per the ASTM procedure.

Chapman Avenue, Orange, CA 92866 File APPENDIX L: CULTURAL RESOURCE RECORDS SEARCH RESULTS Project #20221225.001A 1 of 5 September 13, 2021 © 2021 Kleinfelder September 13, 2021 Mr. Curtis Zacuto EcoTierra Consulting 5776-D Lindero Canyon Road #414 Westlake Village, CA 91362 SUBJECT: Cultural Resources Constraints Desktop Review for the Pepperwood Place Project, City of Anaheim, Orange County, California Dear Mr. Zacuto, Kleinfelder has prepared the following cultural resources constraints desktop review for the proposed development of a 12-unit, small lot, single-family residential subdivision located at 910 South Western Avenue, in Anaheim, Orange County, California. The desktop analysis was completed by Kleinfelder Project Manager and Archaeologist Gregorio Pacheco, B.A.; Senior Archaeologist and Cultural Resources Program Manager Rachael Nixon, M.A., RPA, provided the independent technical review of the report. The primary objective of the desktop review is to identify previously recorded cultural resources and previous cultural studies conducted within the project area and a 0.25-mile surrounding buffer area; to summarize potential cultural resources constraints associated with the proposed development of the site; and to provide recommendations and management considerations. PROJECT OVERVIEW The proposed project site is located in a developed neighborhood within the City of Anaheim, in Orange County, California (Figure 1). The proposed project site measures approximately 1.39 acres and is approximately 0.44-mile west of Highway 39 and 0.39 mile south of Carbon Creek, and is located in Township 4 South, Range 11 West, and Section 3 of the Los Alamitos 7.5-minute U.S. Geological Survey (USGS) quadrangle (Figure 2). The proposed project entails development of a 12-unit single-family residential subdivision on approximately 1.39-acres of land located at Assessor’s Parcel Numbers 079-882- 36 and 079-882-37. REVIEW METHODS Kleinfelder requested a records search with the South-Central Coast Information Center (SCCIC) of the California Historical Resources Information System (CHRIS) located at California State University (CSU), Fullerton in Fullerton, California in order to assess potential presence of cultural resources within the proposed project area and a 0.25-mile radius around the project area. The purpose of the record search was to identify if any prehistoric and/or historic-period cultural resources and studies had been previously documented in the project area and/or the surrounding 0.25-mile radius in order to better understand the archaeological sensitivity of the area. Additionally, Kleinfelder requested a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) to verify that Native American gravesites, tribal resources and other cultural and spiritual sites of interests and importance to tribes that are traditionally and culturally affiliated with the project’s geographic area. RESULTS The cultural search through the CHRIS records search of the APE and a 0.25-mile radius was requested to the SCIC on June 25, 2021 and the results were received on August 26, 2021 (I.C. File #22648.8827). The results indicated no previously recorded cultural resources on file with the SCIC were identified within the project area and the 0.25-mile radius. The results also indicated no previously conducted cultural resources Project #20221225.001A 2 of 5 September 13, 2021 © 2021 Kleinfelder studies have been completed within the project area and the 0.25-mile radius. Therefore the sensitivity of the project area is unknown as it has not been previously surveyed for cultural resources. The results can be seen in Appendix A. On June 28, 2021, a SLF was requested to the NAHC of the APE and a 0.25-mile radius and the results were received on July 21, 2021. The search resulted positive and contacting the Gabrieleno/Tongva San Gabriel Band of Mission Indians was recommended as tribes do not always record their sacred sites in the SLF. A Native American tribes contact list who may also have knowledge of cultural resources in the project area was provided. No further Native American coordination was completed as it is assumed this will conducted by the City of Anaheim. The results can be seen in Appendix B. CONCLUSIONS AND RECOMMENDATIONS The cultural resources desktop review of the approximately 1.39-acre project area, included the records search results from the SCCIC and SLF search results from the NAHC. The SCCIC records search efforts concluded with negative results for previously recorded cultural resources and previously conducted cultural resources studies within the project area and the 0.25-mile radius. The negative results from the SCCIC indicate the project area has never been surveyed and therefore it is unknown if archaeological resources are present within the project area. Additionally, the SLF search resulted positive and the NAHC recommends contacting the Gabrieleno/Tongva San Gabriel Band of Mission Indians was. The NAHC also recommended to contact other Native American tribes from the provided contact list who may also have knowledge of cultural resources in the project area. Based on the results provided by the SCCIC and SLF searches, the project area and surrounding vicinity have never been surveyed for archaeological resources. As such, Kleinfelder recommends the project proponent should obtain the services of a qualified archaeologist to be on-call in the event of any subsurface archaeological materials and provide workers with a one-day training for awareness and procedures to follow in the event of inadvertent findings. Kleinfelder also recommends the City follow up with the Gabrieleno/Tongva San Gabriel Band of Mission Indians and other Native American tribes to determine if there are any known tribal cultural resources within the project area and coordinate with the Tribe(s) to develop appropriate conditions, if warranted. Kleinfelder archaeologist can support the City with contacting the tribes and supporting with further outreach, as needed.

Thank you for using the California Historical Resources Information System, Isabela Kott Assistant Coordinator, GIS Program Specialist Enclosures: (X) COVID -19 EMERGENCY Records Search Protocols for LA, Orange and Ventura Counties – 2 pages COVID -19 EMERGENCY Records Search Protocols for LA, Orange and Ventura Counties – Custom Maps instead of Shape Files These instructions are for qualified consultants with a valid Access and Use Agreement. These instructions are for those of you who cannot accept shape files as a deliverable and need us to make you a custom map of the resource and report locations. Please note that you are charged for each map feature even if you opt out of receiving custom maps. You cannot get secondary products such as bibliographies or pdfs of records if you don’t pay for the primary products (custom map features) as this is the scaffolding upon which the secondary products are derived. If you opt out of having us make you a custom map then you are not charged for the ”time” to make you a custom map. If you do not understand the digital fee structure, ask before we process your request and send you data. You can find the digital fee structure on the OHP website under the CHRIS tab. In order to keep costs down, you must be willing to make adjustments to the search radius or what you are expecting to receive as part of the search. Remember that some areas are loaded with data and others are sparse – our fees will reflect that. WE ARE ONLY PROVIDING DATA THAT IS ALREADY DIGITAL AT THIS TIME. For LA, Orange, and Ventura Counties, this is good news because we are almost fully digital. The exception to this is that not all of our reports are scanned. You can submit a second request for any unscanned documents when we are back in the office (fees apply). INSTRUCTIONS FOR SUBMITTING A RECORD SEARCH: There is a one-hour minimum per invoice. Use one data request form for each project search. Please send in your requests via email to SCCIC@fullerton.edu using the data request form along with the associated shape files and pdf maps of the project area(s) at 1-24k scale. PDFs must be able to be printed out on 8.5X 11 paper. We check your shape file data against the pdf maps. This is where we find discrepancies between your shape files and your maps. This is required. If you do not submit shape files of your project area, you will be charged for our time to draw your project area digitally so that we can process your request. Any “special instructions” must be noted on the data request form – not in the body of an email. Please use this data request form and make sure you fill it out properly. http://web.sonoma.edu/nwic/docs/CHRISDataRequestForm.pdf DELIVERABLES: 1. A copy of the Built Environment Resources Directory or BERD for Los Angeles, Orange, Ventura, or San Bernardino County can now be found at the OHP Website for you to do your own research. This replaces the old Historic Properties Directory or HPD. We will not be searching this for you at this time but you can search it while you are waiting for our results to save time. 2. You will get custom maps of resource locations for the project area and the radius that you choose. For report locations you can request any radius you like, but we will only be providing custom maps of report locations for the project area and up to a ¼-mile radius. If you don’t see a report plotted on the map then it’s outside of the ¼-mile radius. You can ask for a project area only search if the lead agency or your client will accept a project area only search. 3. You will receive the type of bibliography that you select on the data request form and in accord with the search radius that you selected. If you need bibliographic information for reports for more than ¼-mile radius – you will be charged for all report map features within your selected search radius – even if they are not mapped. 4. You will get pdfs of resources and reports in accord with the search radius if you request them, provided that they are in digital formats. We will not be scanning records or reports at this time. 5. You will get one invoice per data request form. There is a one-hour minimum per job. 6. We will be billing you at the staff rate of $150 per hour and you will be charged for all resources and report locations according to the “custom map charges”. You will also be billed 0.15 per pdf page, or 0.25 per excel line as is usual. Quad fees will apply if your research includes more than 2 quads. 7. A copy of the digital fee structure is available on the Office of Historic Preservation website under the CHRIS tab. If the digital fee structure is new to you or you don’t understand it; please ask questions before we process your request, not after. Thank you 8. Your packet will be sent to you electronically via Dropbox. We use 7-zip to password protect the files so you will need both on your computers. We email you the password. If you can’t use Dropbox for some reason, then you will need to provide us with your Fed ex account number and we will ship you a disc with the results. As a last resort, we will ship on a disc via the USPS. You may be billed for our shipping and handling costs. I may not have been able to cover every possible contingency in this set of instructions and will update it if necessary.

Via Email to: gpacheco@kleinfelder.com Re: 20221225.001A Bio and Cult Pepperwood Place Anaheim Project, Orange County Dear Mr. Pacheco: A record search of the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) was completed for the information submitted for the above referenced project. The results were positive. Please contact the Gabrieleno/Tongva San Gabriel Band of Mission Indians on the attached list for information. Please note that tribes do not always record their sacred sites in the SLF, nor are they required to do so. A SLF search is not a substitute for consultation with tribes that are traditionally and culturally affiliated with a project’s geographic area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites, such as the appropriate regional California Historical Research Information System (CHRIS) archaeological Information Center for the presence of recorded archaeological sites. Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. Please contact all of those listed; if they cannot supply information, they may recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from tribes, please notify the NAHC. With your assistance, we can assure that our lists contain current information.

RECOMMENDATION: Staff recommends that the Planning Commission, by motion, determines that the proposed actions are exempt from the requirements to prepare additional environmental documentation per California Environmental Quality Act (CEQA) Guidelines Sections 15061(b)(3); and the Legislature has declared that this ordinance, which implements the provisions of Government Code Section 65852.21, is not a project under CEQA or the CEQA Guidelines; and recommend City Council approval of DEV2021-00216 for a Zoning Code Amendment implementing Senate Bill 9, including Adjustment No. 12 to the Anaheim Canyon Specific Plan No. 2015-1 and Adjustment No. 5 to the Beach Boulevard Specific Plan No. 2017-1. BACKGROUND: On September 16, 2021, the State Legislature approved Senate Bill 9 (SB9). SB9 requires cities to allow, by right, two residential dwelling units on any lot in a single family zone (Two-Unit Development) and requires cities to ministerially allow the subdivision of one existing single family zoned lot into two lots (Urban Lot Split). Both sections could be used together to yield a maximum of two lots, and two units on each lot that are a minimum of 800 square feet in area each must be permitted subject to certain requirements and prohibitions. If an Urban Lot Split is requested, each lot must be a minimum of 1,200 square feet in area. Properties that have been subdivided by Urban Lot Split may not be subdivided again. SB9 outlines various limitations and requirements, but allows the City to adopt objective zoning, design, and subdivision standards for both Two-Unit Developments and Urban Lot Splits (provided that they do not conflict with SB9). In addition, the new law adds another 12 months to the time a tentative parcel map can be extended. SB9 becomes effective January 1, 2022. Currently, the Anaheim Municipal Code (AMC) would allow one single family dwelling on a single-family zoned lot with the possibility of up to two additional dwelling units using the City’s adopted Accessory Dwelling Unit and Junior Accessory Dwelling Unit (ADU and JADU) code. Any subdivision of land would require a public hearing before the Planning Commission for a tentative parcel or tract map. A final map would then be required through the Public Works Department. 200 S.

SB9 states that sites with the following designation or developed with the following projects are prohibited from implementing either a Two-Unit Development or an Urban Lot Split: Affordable Housing Tenant Occupied within the last 3 years Rental Terminated within the last 15 years Hazard Waste Site Natural Community Conserviation Planning Act (NCCP) sites Conservation Easement Historic District Other sites located in the following areas may be prohibited with exceptions from developing either a Two-Unit Development or Urban Lot Split unless specific criteria are met to allow development: Very High Fire Hazard Severity Zone Earthquake Fault Zone Special Flood Hazard Zone Regulatory Floodway To help determine eligibility for implementation of Two-Unit Developments and Urban Lot Splits, staff is preparing a map which will depict these exclusion areas. This map may be updated from time to time as designations and land uses change. Procedural Requirements. Part of SB9 states that review of Two-Unit Developments and Urban Lot Splits must be conducted ministerially. Staff anticipates the review of Two-Unit Developments to be similar to current ADU review which involves submittal of construction drawings into the Building Division for plan check review subsequent to verification of clearance from site prohibitions. For the subdivision of one property into two, the AMC currently requires the submittal of a tentative parcel map for discretionary review by the Planning Commission. Since SB9 requires a ministerial review of the subdivision, amendments to the AMC include procedural changes to create an administrative review process for the tentative parcel map. In addition, Chapter 17.08 Subdivisons will be updated to include a defintion of Urban Lot Split. The subdivision would be processed as an administrative permit with approval authority by the Planning Director. This decision of the Planning Director will be final without the opportunity to appeal or request variances to keep the process ministerial as required by SB9. Subsequent to tenative parcel map approval, a Parcel Map would be processed administratively with the Public Works Department. Code Comparison. Staff has prepared the attached draft ordinance to implement SB9. It includes SB9 requirements and creates objective standards where provided for in SB9. The following tables identify key development standards and compares SB9 with proposed changes to the AMC for Two- Unit Developments and Urban Lot Splits.

Same as SB9 DEVELOPMENT PROJECT NO. 2021-00216 December 6, 2021 Page 5 of 8 Urban Lot Split Criteria State Law Proposed Urban Lot Split Code Minimum Lot Size 1,200 1,200 PROPOSAL: This proposal would amend Title 18 (Zoning) of the AMC in response to the aforementioned changes to SB 9 pertaining to Two-Unit Developments and Urban Lot Splits. The proposed code amendment would modify the following chapters of the AMC: • 17.08 (Subdivisions) • 18.04 (Single-Family Residential Zones) • 18.06 (Multiple-Family Residential Zones) • 18.08 (Commercial Zones) • 18.10 (Industrial Zone) • 18.14 (Public and Special-Purpose Zones) • 18.20 (Platinum Triangle Mixed Use (PTMU) Overlay Zone) • 18.36 (Types of Uses) • 18.38 (Supplemental Use Regulations) • 18.42 (Parking and Loading) • 18.62 (Administrative Reviews) • 18.92 (Definitions) • 18.120 (Anaheim Canyon Specific Plan No. 2015-1 (SP 2015-1) • 18.122 (Beach Boulevard Specific Plan No. 2017-1 (SP 2017-1) ANALYSIS: Staff recommends that the City Council adopt an ordinance to amend the AMC to provide consistency with SB9 for the specific provisions that municipalities must implement. SB9 also gives municipalities some discretion in adopting their respective Code requirements for Two- Unit Developments and Urban Lot Splits. In those instances, staff recommends AMC requirements that are more restrictive than what SB9 allows. In addition, staff drafted the proposed amendments to the AMC in a way that streamlines the development standards to help property owners understand the different options and regulations associated with construction and subdivision of land. The following includes an analysis of the provisions that the City can regulate as part of its SB9 ordinance along with staff’s main recommendations for implementation of these regulations. Minimum Unit Size: SB9 does not establish a minimum unit size. To facilitate livable units, staff recommends a minimum 400 square foot unit size, consistent with a typical two car garage. Maximum Unit Size: SB9 does not specify a maximum unit size for Two-Unit Developments; however, it does specify that cities have to allow a minimum 800 square foot unit. Staff recommends that Two-Unit Developments be limited to the smallest unit size allowed by SB9, which is 800 square feet. Lot Coverage: SB9 does not regulate lot coverage except that any objective standards that preclude the construction of two 800 square foot units is prohibited. Given the small lot sizes anticipated DEVELOPMENT PROJECT NO. 2021-00216 December 6, 2021 Page 6 of 8 for Two-Unit Development and that unit size will be limited, staff recommends the elimination of the maximum lot coverage requirement to streamline project review. Structural Height: SB9 does not regulate structural height. Staff recommends that the maximum permitted height for any attached Two-Unit Development be subject to the underlying zone. For detached units, staff recommends a maximum height of 16 feet or the height of the main dwelling unit, whichever is greater. This will prevent the Two-unit Development from being out of scale with the main dwelling unit. Given that an attached Two-Unit Development will visually appear as an addition to the main dwelling unit, staff recommends that the maximum height of an attached unit be the same as the height permitted by the underlying zone. Structural Setbacks: SB9 requires that side and rear yard setbacks cannot be greater than four feet. Municipalities have the discretion to determine the minimum structural setbacks along the front of the property. Staff recommends that the city require front setbacks based on the underlying zone to maintain a consistent street scene. Building Separation: SB9 provides municipalities with the discretion to establish building separation requirements between structures on the same property provided it does not become the reason a project is not approved. It further states that the separation must meet building safety requirements and are adequate to allow separate conveyance. Staff recommends a minimum 10- foot building separation between detached structures. Staff recommends this dimension to provide for additional privacy, ensure adequate open space between the two units and to avoid building code issues. Design: SB9 allows municipalities the discretion to ensure that Two-Unit Developments are compatible with existing structures and surrounding neighborhoods using objective design standards. Staff recommends incorporating the same language used in the single family zones for building articulation so that Two-Unit Developments are held to the same design standard as all other single family homes in the City. Non-conformities: SB9 stipulates that existing structures may be retained and existing structures may be demolished and rebuilt in its pre-existing location and size. In addition to adopting the state provisions, staff recommends that for Two-Unit Developments, all other non-conformities comply with the zoning code chapter. For Urban Lot Splits, SB9 further stipulates that cities may not require correction of nonconforming zoning conditions therefore any legal non-conformities may remain for the subdivision. Staff recommends that subsequent development on property subdivided under the Urban Lot Split comply with the Two-Unit Development standards. Sewer Deficient Areas: SB9 allows municipalities to prohibit Two-Unit Developments and Urban Lot Splits in prohibited areas identified above. In addition, SB9 allows a city to deny a Two-Unit Development or Urban Lot Split if the development would have a specific, adverse impact on public health and safety or the physical environment when there is no feasible method to satisfactory mitigate or avoid the impact. This determination is made by written finding of the building official. Staff anticipates that development on parcels with a known sewer deficiency will be a specific, adverse impact of concern to the building official. Parcels affected by a sewer deficiency are currently prohibited from development of ADU and JADUs. These properties have been identified by the City Engineer and are depicted on a map approved by resolution of the City Council. Although this limitation is not a known prohibition, development of additional dwelling units in areas with insufficient sewer infrastructure is a matter of public health and safety. DEVELOPMENT PROJECT NO. 2021-00216 December 6, 2021 Page 7 of 8 Administrative Urban Lot Split: SB9 mandates that parcel maps requested under an Urban Lot Split must be processed ministerially but in compliance with the Subdivision Map Act. It further states that the City may not condition the parcel map to provide dedications of rights-of-way or construction of off-site improvements. SB9 provides that cities are allowed to require access to a public right-of-way and easements for public services. Staff recommends that all parcels created through an Urban Lot Split have a minimum frontage of 25 feet on a public street. Additionally, in order to prevent structures that are out of scale with the land area created from an Urban Lot Split, development must comply with the Two Unit Development standards. The law further limits parcels eligible for subdivision so that existing affordable or rental housing is not diminished or converted. Staff has created a new administrative review process for Urban Lot Splits in Chapter 18.62 (Administrative Reviews) to identify a method to ministerially review tentative parcel maps. Staff will be tracking these applications in order to ensure that properties that have previously subdivided through an Urban Lot Split are not subdivided again and that individuals who have previously split an adjacent parcel are unable to request another Urban Lot Split, as required by law. An application fee for the tentative parcel map portion of an Urban Lot Split will be established to recover the cost of staff time to review the parcel map. An updated fee resolution will be presented to the City Council at an upcoming meeting to establish this new fee. Environmental Impact Analysis: Staff recommends that the Planning Commission find that the proposed ordinance is not subject to the California Environmental Quality Act (CEQA). This determination is pursuant to Section 15061(b)(3) of the CEQA Guidelines. Pursuant to this section, the proposed amendments and adjustments fit within the general rule that CEQA only applies to projects that have the potential for causing a significant effect on the environment. In that, the proposed amendments and adjustments would create consistency and amend Code requirements to reflect State law, the proposed adjustments and amendments will not have a significant effect on the environment; and, therefore, the activity is not subject to CEQA. In addition, the Legislature has declared that this ordinance, which implements the provisions of Government Code Section 65852.21, is not a project under CEQA or the CEQA Guidelines. CONCLUSION: The proposed amendments are in response to the adoption of SB9 which becomes effective January 1, 2022. The new law includes specific provisions that municipalities must implement; however, the legislation gives the City minimal discretion in adopting its Two- Unit Development and Urban Lot Split ordinance. Staff recommendations included in the draft ordinance are intended to minimize impacts to surrounding and existing residential neighborhoods while ensuring compliance with SB9. As such, staff recommends that the Planning Commission, by motion, recommend approval of the proposed Zoning Code Amendment to the City Council.
