ITEM NO. 6
PLANNING COMMISSION REPORT
City of Anaheim
PLANNING AND BUILDING DEPARTMENT
DATE: DECEMBER 5, 2022
SUBJECT: DEVELOPMENT APPLICATION NO. 2021-00193
(GENERAL PLAN AMENDMENT)
LOCATION: Roadways within the City of Anaheim include a portion of Yorba
Linda Boulevard from the eastbound SR-91 interchange to La Palma Avenue, Savi
Ranch Parkway, Crystal Drive, Pullman Street, and Old Canal Road; and La Palma
Avenue between Yorba Linda Boulevard and the East City Limits.
REQUEST: This is a City-initiated request to amend the Circulation Element of
the City’s General Plan including the Bicycle Master Plan for portions of Yorba
Linda Boulevard, Savi Ranch Parkway, Crystal Drive, Pullman Street, Old Canal
Road, and La Palma Avenue for consistency with existing conditions and a
conditionally-approved amendment to the Master Plan of Arterial Highways
(MPAH); to add planned bicycle infrastructure; and to revise maps, figures, text, and
tables throughout the General Plan to reflect these changes.
RECOMMENDATION: Staff recommends that the Planning Commission, by
resolution, recommend that the City Council determine that Addendum No. 4 to the
previously certified Environmental Impact Report No. No. 330 (EIR 330) and
Supplemental Environmental Impact Report No. 346 (SEIR 346), is the appropriate
environmental documentation for this request; and, that the City Council approve a
General Plan Amendment associated with Development Application No. 2021-00193
(Attachment 1).
BACKGROUND: In May 2004, the City of Anaheim adopted a comprehensive
update of the City’s General Plan. The Circulation Element is one of the General Plan
elements, the purpose of which is to design and improve a circulation system to meet
the current and future needs of all Anaheim residents, businesses, and visitors. The
Bicycle Master Plan is included as Appendix B to the Circulation Element. The City
Council has approved numerous General Plan amendments, including to the
Circulation Element and Bicycle Master Plan, since adoption in furtherance of an
efficient and effective circulation system.

On May 11, 2020, the Yorba Linda Boulevard Widening Project (Project), was selected by the Orange
County Transportation Authority (OCTA) to receive grant funds for design engineering and project
administration. The Project area encompasses roadway improvements in the cities of Anaheim and
Yorba Linda as depicted in Figure 1, below. Improvements are proposed along Yorba Linda
Boulevard / Weir Canyon Road encompassing approximately 0.50 miles between La Palma Avenue
and Santa Ana Canyon Road; and along La Palma Avenue encompassing approximately 0.65 miles
moving easterly from the Yorba Linda Boulevard and La Palma Avenue intersection. The proposed
Project would improve traffic and other public infrastructure along Weir Canyon Road, Santa Ana
Canyon Road, and Yorba Linda Boulevard. The proposed Project would also increase multi-modal
transportation with the inclusion of a Class I bike path providing connectivity between the existing
bike and pedestrian facilities along La Palma Avenue, the Santa Ana River Trail, Yorba Linda
Boulevard, and access to the Savi Ranch development.

Source: Final Initial Study / Mitigated Negative Declaration (SCH. No. 2020100085)
On January 19, 2021, the City Council of the City of Yorba Linda, as the Lead Agency for the Project,
adopted a Mitigated Negative Declaration (MND) and Mitigation Monitoring and Reporting Program
(MMRP) for construction and operation of the Project. Subsequently, on February 15, 2022, City
Council of the City of Anaheim authorized the Public Works Department to execute a Cooperative
Agreement with the City of Yorba Linda to share in the costs associated with the required local match
for the engineering phase of the Project.
In order to proceed with the Project and maintain grant funding, amendments to the OCTA MPAH
and the General Plans of the cities of Yorba Linda and Anaheim are required to maintain consistency
between each jurisdictions’ long-range transportation plans and with the MPAH.
Development Application No. 2021-00193
December 5, 2022
Page 3 of 5
On July 12, 2021, the cities of Anaheim and Yorba Linda requested and received conditional approval
from the OCTA Board of Directors for the MPAH amendments. As a condition for final approval,
OCTA must receive approved amendments to the Circulation Elements of the cities of Anaheim and
Yorba Linda for consistency with the MPAH amendments within three years. On March 1, 2022, the
City Council of Yorba Linda approved their amendment to the Circulation Element.
PROPOSAL: Staff is proposing amendments to the Circulation Element of the General Plan
including the Bicycle Master Plan to resolve inconsistencies with existing conditions and provide
consistency with the MPAH, as conditionally amended.
• Yorba Linda Boulevard 1. Yorba Linda Boulevard, generally a six-lane divided facility, is
currently classified as a Primary Arterial, but is designed and operating as a Major Arterial. The
amendment would include the following actions:
○ Reclassify Yorba Linda Boulevard from the SR-91 eastbound on-ramp on the south to La
Palma Avenue on the north from a Primary Arterial to a Major Arterial in order to match the
existing condition of the roadway. The Scenic Expressway designation would remain in place
beginning south of the SR-91 interchange on Weir Canyon Road; and
○ Add a planned Class I Bike Path on the east side of Yorba Linda Boulevard. The Class I Bike
Path would stretch between La Palma Avenue on the north and Old Canal Road on the south.
• Savi Ranch Parkway. Savi Ranch Parkway is a four-lane divided facility within the City, not
currently identified in the City’s Circulation Element. The Primary Arterial classification typically
applies to four-lane divided facilities with left turn pockets and parking lanes. The amendment
would add Savi Ranch Parkway from the City’s boundary line at Yorba Linda Boulevard to
Crystal Drive and Pullman Street as a Primary (four-lane, divided) Arterial to match the existing
condition of the roadway.
• Crystal Drive / Pullman Street / Old Canal Road. Crystal Drive, Pullman Street, and Old Canal
Road are currently two-lane divided facilities that provide a loop connection from each end of
Savi Ranch Parkway. There are no through movements at the Savi Ranch Parkway / Yorba Linda
Boulevard intersection, as this intersection only provides left- and right-turn lanes from both
eastbound and westbound Savi Ranch Parkway onto Yorba Linda Boulevard. Therefore, Crystal
Drive, Pullman Street, and Old Canal Road function as a couplet to route travelers to either side
of Yorba Linda Boulevard.2 The City’s Circulation Element currently does not identify Crystal
Drive, Pullman Street / Old Canal Road on the Planned Roadway Network or provide a
classification for this roadway. The amendment would add Crystal Drive, Pullman Street / Old
Canal Road classified as Collector Streets (two-lane, divided) in order to provide a classification
consistent with the existing configuration of the roadway.
• La Palma Avenue. This portion of La Palma Avenue is classified as a Secondary Arterial, and
no changes are proposed to the Roadway classification. The amendment would add a planned
1 Yorba Linda Boulevard becomes Weir Canyon Road south of SR-91.
2 Pullman Street is called Old Canal Road where it crosses underneath Yorba Linda Boulevard and connects with
Savi Ranch Parkway within the City of Yorba Linda’s jurisdiction.

Class I Bike Path on the south side of La Palma Avenue between Yorba Linda Boulevard on the
west and the City boundary on the east.
All of these amendments would result in associated revisions to appropriate maps, figures, text, and
tables throughout the General Plan to reflect the described changes.
FINDINGS AND ANALYSIS: Before the Planning Commission can recommend approval of a
General Plan Amendment to the City Council, it must make the following findings:
a) The proposed amendment maintains the internal consistency of the General Plan;
b) The proposed amendment would not be detrimental to the public interest, health, safety,
convenience or welfare of the City;
c) The proposed amendment would maintain the balance of land uses within the City; and
d) If the amendment is to the General Plan Land Use Map, the subject property is physically
suitable to accommodate the proposed modification, including but not limited to, access,
physical constraints, topography, provision of utilities, and compatibility with surrounding
land uses.
The proposed General Plan Amendment meets the above findings because the proposed changes to
the Circulation Element of the General Plan including the Bicycle Master Plan remain consistent with
General Plan Goals to provide a comprehensive multimodal transportation system that facilitates
current and long-term circulation of people and goods in and through the City, and to protect and
encourage bicycle travel. The proposed amendments are also consistent with the General Plan Policies
to assign street classifications to provide an acceptable level of service based on projected traffic
demands, circulation functions, and the areas they are intended to serve while maintaining
coordination with the OCTA MPAH and circulation plans of adjacent cities, to provide safe, direct,
and continuous bicycle routes for commuter and recreational cyclists, and to implement a bikeway
system with linkages to routes in neighboring jurisdictions and regional bicycle routes.
The proposed General Plan Amendment would not be detrimental to the public interest, health, safety,
convenience, or welfare of the City in that the proposed amendment would reclassify or add roadway
classifications based on existing conditions and that the addition of planned bicycle facilities are
expected to improve connectivity and bicycling as a mode of transportation.
The proposed General Plan Amendment would not result in changes to land uses or development
assumptions.
Environmental Impact Analysis: An Addendum to the previously-certified Environmental Impact
Report (EIR) No. 330 and Supplemental Environmental Impact Report (SEIR) No. 346, has been
prepared pursuant to provision of State CEQA Guidelines Section 15164 in order to determine
whether the proposed General Plan Amendment would cause any significant environmental impacts
which were not previously identified or cause previously identified significant impacts to be
substantially more severe. As more thoroughly described in Addendum No. 4, none of the conditions
described in Sections 15162 of the State CEQA Guidelines calling for the preparation of a subsequent
Development Application No. 2021-00193
December 5, 2022
Page 5 of 5
or supplemental EIR or negative declaration have occurred. Addendum No. 4 compared anticipated
environmental effects of the General Plan Amendment with those disclosed in the EIR No. 330 and
SEIR No. 346 and concluded that the prior conclusions remain valid.
CONCLUSION: Staff has carefully considered the General Plan Amendment which resolves
inconsistencies with the existing conditions, provides consistency with the MPAH, and further
supports goals and policies of the General Plan. Staff recommends approval.

1.0 INTRODUCTION
1.1 PURPOSE AND SCOPE
In May 2004, the City of Anaheim (City) Council certified Environmental Impact Report (EIR) No. 330
(referred to as the “2004 Certified EIR No. 330” or “EIR No. 330”) in conjunction with its adoption of
a comprehensive update of Anaheim’s General Plan and Zoning Code. Subsequent to this update,
the Anaheim City Council has approved numerous General Plan amendments. The Bicycle Master
Plan is Appendix B to the Circulation Element.
In September 2013, the Anaheim City Council certified Supplemental Environmental Impact Report
(SEIR) No. 346 (referred to as the “2013 SEIR No. 346” or “SEIR No. 346”) in conjunction with the
Housing Opportunities Sites Rezoning Project. SEIR No. 346 is a supplemental EIR to EIR No. 330.
Following the certification of SEIR No. 346, three addenda have been adopted for subsequent
projects, as follows:
• Addendum No. 1 (Bicycle Master Plan)
• Addendum No. 2 (Olson East Street Townhomes Project)
• Addendum No. 3 (Nohl Ranch Open Space Trail Project)
This document collectively refers to EIR No. 330 and SEIR No. 346 as the “Certified EIR” and refers to
the General Plan Circulation Element including the Bicycle Master Plan, as last amended, as the
“approved project.”
The Certified EIR serves as the programmatic environmental document for which future projects
may tier off, including the three prior addenda prepared for subsequent projects.
This Addendum No. 4 to the Certified EIR has been prepared to evaluate the environmental impacts of
the proposed amendments to the General Plan Circulation Element including the Bicycle Master Plan
pertaining as detailed in the Project Description, Chapter 2.0.
Under Section 15162 of the State CEQA Guidelines, a subsequent EIR is not required for the
proposed changes unless the City determines on the basis of substantial evidence that one or more
of the following conditions are met:
1. Substantial changes are proposed in the project which will require major revisions of the
previous EIR or Negative Declaration due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified significant effects;
2. Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions of the previous EIR or Negative Declaration due to
the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified significant effects; or

3. New information of substantial importance, which was not known and could not have been
known with the exercise of reasonable diligence at the time the previous EIR was certified as
complete or the Negative Declaration was adopted, shows any of the following:
a. The project will have one or more significant effects not discussed in the previous EIR;
b. Significant effects previously examined will be substantially more severe than shown in the
previous EIR;
c. Mitigation measures or alternatives previously found not to be feasible would in fact be
feasible, and would substantially reduce one or more significant effects of the project, but
the project proponents decline to adopt the mitigation measure or alternative; or
d. Mitigation measures or alternatives which are considerably different from those analyzed in
the previous EIR would substantially reduce one or more significant effects on the
environment, but the project proponents decline to adopt the mitigation measure or
alternative.
Section 15164 of the State CEQA Guidelines states that an Addendum to an EIR shall be prepared “if
some changes or additions are necessary, but none of the conditions described in Section 15162
calling for preparation of a subsequent EIR have occurred.” Thus, if none of the above conditions are
met, the City may not require preparation of a subsequent or supplemental EIR. Rather, the City can
decide that no further environmental documentation is necessary or can require that an Addendum
be prepared.
This Addendum reviews changes to the approved project and to existing conditions that have
occurred since the Certified EIR was approved and compares environmental effects of the proposed
project with those analyzed and previously disclosed under the approved project. This Addendum
also considers new information of substantial importance that was not known and could not have
been known with exercise of reasonable diligence at the time the Certified EIR was certified and
evaluates whether there are new or more severe significant environmental effects associated with
changes in circumstances under which project development is being undertaken. It further examines
whether, as a result of any changes or any new information, a subsequent or supplemental EIR may
be required. This examination includes an analysis of provisions of Public Resources Code (PRC)
Section 21166 and Section 15162 of the State CEQA Guidelines and their applicability to the project.
On May 2004, a Final Environmental Impact Report (Anaheim General Plan and Zoning Code Update
FEIR No. 330 [State Clearinghouse (SCH) No. 2003041105]) was certified by the Anaheim City Council
along with a Mitigation Monitoring and Reporting Program (MMRP). In addition, the findings of fact
for the Anaheim General Plan and Zoning Code Update FEIR noted significant unavoidable adverse
impacts related to air quality, noise, greenhouse gas emissions, and traffic. Therefore, a statement
of overriding considerations was also adopted. In September 2013, the Anaheim City Council
certified Supplemental EIR (SEIR) No. 346 in conjunction with the Housing Opportunities Sites
Rezoning Project. SEIR No. 346 is a supplemental EIR to EIR No. 330. SEIR No. 346 concluded that
similar to EIR No. 330, impacts related to air quality, greenhouse gas emissions, noise, and
transportation would remain significant and unavoidable.

Pursuant to the provisions of CEQA and the State CEQA Guidelines, the City is the Lead Agency
charged with the responsibility of deciding whether to approve the proposed project, in
consideration of the potential environmental effects that could result from project implementation
compared to the environmental effects previously analyzed for the approved project.
The City’s review of the proposed project is limited to examining environmental effects associated
with differences between the proposed project and the approved project. Pursuant to CEQA and the
State CEQA Guidelines, the City has prepared this Addendum No. 4 to the Certified EIR to provide
decision-makers with a factual basis for evaluating the specific environmental impacts associated
with proposed project and to determine whether there are changes in circumstances or new
information of substantial importance that would require preparation of a subsequent or
supplemental EIR.
EIR No. 330 and SEIR No. 346 (collectively, the “Certified EIR “) remain valid and constitute the
certified CEQA documentation for future planning actions associated with implementation of the
Circulation Element. As such, the Certified EIR, along with this Addendum, will be used to determine
whether the proposed project falls within the scope of the approved project as analyzed in the
Certified EIR.
Based upon review of the facts as presented in the analysis contained in this document, the City
finds that an Addendum to the previous Certified EIR is the appropriate documentation to comply
with CEQA. The rationale and the facts for this finding are provided in the body of this Addendum.
1.2 EVALUATION OF ENVIRONMENTAL IMPACTS
1.2.1 Approved Project
1.2.1.1 EIR Process for EIR No. 330
Consistent with Section 15063 of the State CEQA Guidelines, City staff determined that a Program
EIR was the appropriate environmental document to be prepared for the approved project (refer to
Section 1.2.1.2, Type of EIR, below for more information regarding the decision to prepare a
Program EIR). The SCH issued a project number for EIR No. 330 (SCH No. 2003041105). In
accordance with the State CEQA Guidelines, Section 15082, the Notice of Preparation (NOP) was
circulated in April 2003 to responsible agencies and individuals for a period of 30 days, during which
time written comments were solicited pertaining to environmental issues and topics that the EIR
should evaluate.
The Draft EIR was circulated for public review for the required 45-day public review period, from
March 19, 2004, to May 3, 2004. The City Council certified the Final EIR in May 2004 and approved
the project.
1.2.1.2 Type of EIR (2004 Certified EIR No. 330)
The 2004 Certified EIR No. 330 serves as a Program EIR pursuant to State CEQA Guidelines,
Section 15168.

The use of a Program EIR provides an occasion for a more exhaustive consideration of effects and
alternatives than otherwise would be practical under a Project EIR. However, subsequent activities
occurring as a result of program/project approval and certification of a Program EIR must be further
evaluated in light of the Program EIR to determine whether or not an additional environmental
document must be prepared. If an agency finds that no new effects could occur and that no new
mitigation would be required, then the agency can determine that subsequent activities are covered
under the Program EIR and no further environmental documentation would be required.
Conversely, an agency may determine that future projects could require the preparation of a new
Initial Study, Mitigated Negative Declaration (MND), or new EIR. If new environmental
documentation is required, a Program EIR can be used to focus the scope of the subsequent
environmental document (State CEQA Guidelines, Section 15168).
EIR No. 330 identified the City’s vision for its development from buildout through 2035 and included
revisions to the existing Land Use Element; the Economic Development Element (which
incorporated the previous Redevelopment Element); the Circulation Element; the Growth
Management Element; the Green Element (which incorporated the previous Parks, Recreation and
Community Services; Open Space; and Conservation Elements); the Noise Element; and the Safety
Element (which incorporated the previous Safety and Seismic Safety Elements). In addition to the
topics addressed in the previous General Plan Elements, new goals, policies, and programs were
developed to address community design, economic development, and public services and facilities.
EIR No. 330 also involved a comprehensive update to Title 18 of the Anaheim Municipal Code, which
contains the City’s zoning regulations. Title 18 was amended to implement the updated General Plan
and included innovative zoning solutions that convey community expectations for future
development. Other actions included amendments to the Anaheim Stadium Master Land Use Plan
and/or the development of an overlay zone for this area, the Anaheim Resort Specific Plan, the
Northeast Area Specific Plan, zoning reclassifications within the Cypress Canyon Specific Plan Area,
and portions of the Anaheim Colony Historical District consistent with and necessary to implement
the General Plan and Zoning Code Update.
Subsequent activities associated with implementation of the approved project that would require
approval of a discretionary action would require a project-specific analysis of environmental impacts
associated with implementing maps, plans, and approvals. When reviewing future projects, the City
would utilize the tiering provisions in CEQA to determine whether, in the light of project-specific
circumstances, EIR No. 330 prepared for the approved project would still provide an adequate
description of the broad effects of future projects as they are considered. Following this approach, a
Supplemental EIR was prepared in 2013 for the Housing Opportunities Sites Rezoning Project, which
tiered from the 2004 Certified EIR No. 330 as described below.
1.2.1.3 EIR Process for SEIR No. 346
The City determined that preparation of an SEIR (California Code of Regulations [CCR] Title 14,
Division 6, Chapter 3, Article 11; State CEQA Guidelines Section 15163) was the appropriate
documentation for the Housing Opportunities Sites Rezoning Project. This SEIR addressed the
environmental effects associated with the rezoning of properties identified as Housing
Opportunities Sites to facilitate "by-right" residential development at these locations as well as

updating the General Plan's Land Use Build-out Estimates and facilitating streamlined review per the
Statutory Infill Housing Exemption and Senate Bill (SB) 226. As such, this SEIR need only contain
information necessary to make the City’s previous 2004 Certified EIR No. 330 adequate. As an SEIR,
the SCH filed the documentation related to the SEIR under the Program EIR number (SCH No.
2003041105). In accordance with State CEQA Guidelines, Section 15082, the NOP was circulated in
October 2012 to responsible agencies and individuals for a period of 30 days, during which time
written comments were solicited pertaining to environmental issues and topics that the SEIR should
evaluate.
The Draft SEIR was circulated for public review for the required 45-day public review period, from
July 15, 2013, to August 28, 2013. The City Council certified the Final SEIR in September 2013 and
approved the project.
1.2.1.4 Type of EIR (2013 Certified SEIR No. 346)
Pursuant to State CEQA Guidelines (14 CCR Section 15163), a lead responsible agency may choose to
prepare a supplement to an EIR if:
1. Any of the conditions described in Section 15162 would require the preparation of a subsequent
EIR, and
2. Only minor additions or changes would be necessary to make the previous EIR apply to the
project in the changed situation.
Section 15163(b) of the State CEQA Guidelines further states that a supplement to an EIR need only
contain the information necessary to make the previous EIR adequate for the project as revised.
The City of Anaheim, as Lead Agency under CEQA, determined that preparation of an SEIR (14 CCR
Section 15163) was appropriate. SEIR No. 346 addressed the environmental effects associated with
the implementation of the Housing Opportunities Sites Rezoning Project. As such, SEIR No. 346 only
contained information necessary to make the previous EIR (the 2004 Certified EIR No. 330)
adequate. The SEIR addressed the potential environmental effects of the Housing Opportunities
Sites Rezoning Project, including effects that may be significant and adverse, evaluated a number of
alternatives to the project, and identified mitigation measures to reduce or avoid adverse effects.
Although environmental impacts of future individual projects occurring as a result of project
approval would be analyzed under and compared against the analysis set forth in EIR No. 330 and
SEIR No. 346, a site-specific analysis is required under CEQA. Following the certification of SEIR No.
346, three addenda have been prepared for subsequent projects.
1.2.2 Proposed Project and Addendum
This Addendum No. 4 compares anticipated environmental effects of the proposed project with
those disclosed in the Certified EIR to review whether any conditions set forth in Section 15162 of
the State CEQA Guidelines requiring preparation of a subsequent or supplemental EIR are met. The
description of the proposed project contained in Section 2.3, in Chapter 2.0, Project Description,
below, establishes the basis for analyzing the proposed project’s potential environmental impacts

compared to the approved project. Potential environmental effects of the proposed project are
addressed for each of the following areas, which were included in the Certified EIR:
• Aesthetics
• Agricultural Resources
• Air Quality
• Biological Resources
• Cultural Resources
• Geology and Soils
• Greenhouse Gas Emissions
• Hazards and Hazardous Materials
• Hydrology and Water Quality
• Land Use and Planning
• Mineral Resources
• Noise
• Population and Housing
• Public Services and Utilities
• Recreation
• Transportation/Traffic
The City had determined in the Certified EIR prepared for the approved project that the following
issues would have less than significant or no impacts: aesthetics, agricultural and forestry resources,
land use and planning, mineral resources, population and housing, and recreation. The proposed
project does not necessitate a change in these determinations as the existing site conditions and
nature of the project have not substantially changed from those identified for the Certified EIR.
Therefore, environmental analysis provided in the Certified EIR remains relevant and applicable to
the proposed project for the areas unaffected by changes for these topic areas. A brief description
of these topics areas is provided in Chapter 3.0 of this Addendum below. Environmental topic areas
that were identified as less than significant with mitigation incorporated or significant and
unavoidable in the Certified EIR include: air quality, biological resources, cultural resources, geology
and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality,
noise, public services and utilities, and transportation and traffic. These topics areas are analyzed in
detail in Sections 3.1 through 3.10 below.
1.3 FINDINGS OF THIS ADDENDUM
The City is the Lead Agency for the proposed project. The City has determined that analyses of
project environmental effects are best provided through the use of an Addendum and that none of
the conditions set forth in PRC Section 21166 or Section 15162 of the State CEQA Guidelines
requiring preparation of a subsequent or supplemental EIR have been met.
1. There are no substantial changes to the project that would require major revisions of the
Certified EIR due to new significant environmental effects or a substantial increase in severity of
impacts identified in the Certified EIR;
2. Substantial changes have not occurred in the circumstances under which the project is being
undertaken that will require major revisions to the Certified EIR to disclose new significant
environmental effects or that would result in a substantial increase in severity of impacts
identified in the Certified EIR; and
3. There is no new information of substantial importance that was not known at the time the
Certified EIR was certified, indicating any of the following:
• The project will have one or more new significant effects not discussed in the Certified EIR;

• There are impacts determined to be significant in the Certified EIR that would be
substantially more severe;
• There are additional mitigation measures or alternatives to the project that would
substantially reduce one or more significant effects identified in the Certified EIR; and
• There are additional mitigation measures or alternatives rejected by the project proponent
that are considerably different from those analyzed in the Certified EIR that would
substantially reduce a significant impact identified in the Certified EIR.
The complete evaluation of potential environmental effects of the project, including rationale and
facts supporting the City’s findings, is contained in Chapter 3.0 of this Addendum.
1.4 FORMAT OF ADDENDUM
This Addendum has been organized into three chapters, as described in the sections below.
1.4.1 Chapter 1.0: Introduction
Chapter 1.0 includes a description of the purpose and scope of the Addendum, previous
environmental documentation, project approvals, findings of the Addendum, and existing
documents to be incorporated by reference.
1.4.2 Chapter 2.0: Project Description
Chapter 2.0 describes the Planning Area, the necessary City discretionary actions to implement the
proposed project, and an overview of the proposed project.
1.4.3 Chapter 3.0: Comparative Evaluation of Environmental Impacts
Chapter 3.0 contains the environmental analyses of the proposed project’s impacts compared to the
impacts of the approved project analyzed in the Certified EIR. This comparative analysis has been
undertaken pursuant to the provisions of CEQA to provide the City of Anaheim decision-makers with
a factual basis for determining whether the proposed project, changes in circumstances, or new
information since EIR No. 330 and SEIR No. 346 were certified, require additional environmental
review or preparation of a subsequent or supplemental EIR. Chapter 3.0 also contains findings for
each environmental topic to determine whether conditions set forth in PRC Section 21166 or
Section 15162 of the State CEQA Guidelines requiring preparation of a subsequent or supplemental
EIR have been met.

2.0 PROJECT DESCRIPTION
2.1 BACKGROUND
The City of Anaheim is proposing minor amendments to the General Plan Circulation Element
including the Bicycle Master Plan in the area of Yorba Linda Boulevard/La Palma Avenue at the
border of the City of Anaheim and City of Yorba Linda.
These amendments would reclassify a segment of Yorba Linda Boulevard as a “Major Arterial”, add
Savi Ranch Parkway as a “Primary Arterial”, and add Crystal Drive, Pullman Street, and Old Canal
Road as “Collector Streets” within the City’s General Plan Circulation Element, and would be
consistent with the existing right-of-way conditions and conditionally approved MPAH. The Orange
County Transportation Authority (OCTA) Board of Directors conditionally approved the MPAH
Amendments across multiple jurisdictions on July 12, 2021, provided that each affected City amends
their General Plans within three years. Additionally, these amendments add a planned Class I Bike
Path on portions of Yorba Linda Boulevard and on La Palma Avenue connecting to the existing Santa
Ana River Trail. It should be noted that construction of the two Class I Bike Paths has also been
evaluated in the Initial Study/Mitigated Negative Declaration (IS/MND) for the Yorba Linda
Boulevard Widening Project approved by the City of Yorba Linda in January 2021. The IS/MND did
not identify any potentially significant impacts associated with the construction of the proposed bike
paths.
Yorba Linda Boulevard has varying configurations through the City. Specifically, pertaining to the
proposed project:
• South of the La Palma Avenue / Yorba Linda Boulevard intersection to the Santa Ana River
Bridge, Yorba Linda Boulevard is currently built as a six-lane facility with three through lanes in
the southbound direction and two through lanes, one through right-turn lane, one right turn
lane, and two left-turn lanes in the northbound direction.
• South of the Santa Ana River Bridge, Yorba Linda Boulevard then straddles the border between
Anaheim and Yorba Linda. Yorba Linda Boulevard between the Santa Ana River Bridge and Savi
Ranch Parkway is currently built as a six-lane facility with three through lanes, one left-turn lane,
and one right-turn lane in the southbound direction and three through lanes, one left-turn lane,
and one right lane split to Savi Ranch Parkway in the northbound direction.
• South of Savi Ranch Parkway to the State Route 91 (SR-91) interchange, Yorba Linda Boulevard is
currently built as a seven-lane facility with three through lanes in addition to dedicated
westbound and eastbound on-ramps in both the northbound and southbound directions. Note:
the seventh lane in the southbound direction becomes an SR-91 merge lane.

Yorba Linda Boulevard, with these varying configurations, experiences an annual average daily
traffic (ADT) of up to 55,500 from La Palma Avenue to the westbound SR-91 off-ramp.1 The existing
configurations of this segment, as described above, exceed the City’s current classification of
Primary Arterial (defined in the current Circulation Element as typically six-lane divided facilities with
no parking lanes or four lane divided facilities with left-turn pockets and two parking lanes). These
configurations also exceed the MPAH’s definition of Primary Arterial, which is typically defined as a
four-lane divided (raised or painted median) roadway, with a typical right-of-way width of 100 feet,
designed to accommodate approximately 30,000 vehicle trips per day at Level of Service (LOS) C.
As a result, the City of Anaheim is proposing to update the Circulation Element to reclassify Yorba
Linda Boulevard from the SR-91 eastbound on-ramp on the south to La Palma Avenue on the north
from a Primary Arterial to a Major Arterial. The Scenic Expressway designation would remain in
place beginning south of the SR-91 interchange on Weir Canyon Road.
The City’s Circulation Element defines a Major Arterial as roadways that connect to freeways and
typically have six lanes, a landscaped median, left-turn pockets, parking lanes adjacent to each curb,
and a right-of-way width of 120 feet. While this is the “typical” configuration of a Major Arterial, the
segment of Yorba Linda Boulevard south of Savi Ranch Parkway would also be consistent with this
classification as a seven-lane, divided roadway that connects to a freeway (SR-91).
The City also is proposing to update the Circulation Element to provide classifications for Savi Ranch
Parkway, Crystal Drive, Pullman Street, and Old Canal Road in the vicinity of this section of Yorba
Linda Boulevard, as discussed in Section 2.3, below.
Additionally, portions of Yorba Linda Boulevard and La Palma Avenue are of sufficient right-of-way
width to include a Class 1 Bike Path with connectivity to the existing Santa Ana River Trail. As a
result, the City of Anaheim is proposing to update the Circulation Element including the Bicycle
Master Plan to add a planned Class 1 Bike Path on the east side of Yorba Linda Boulevard (between
La Palma Avenue and Old Canal Road) and on the south side of La Palma Avenue (between Yorba
Linda Boulevard and the City’s eastern boundary).
2.2 APPROVED PROJECT
2.2.1 Planning Area and Setting

Regional access to the City is provided by SR-91, which traverses the northern portion of the City
from east to west; State Route 57 (SR-57), which traverses the center of the City from north to
south; and Interstate 5 (I-5), which traverses the western portion of the City diagonally from north
to south. In addition, the northern portions of State Route 241 (SR-241) and State Route 55 (SR-55),
which connect to SR-91, are located within the City.
The OCTA maintains stops for several bus transit routes that provide both regional and local access
to and within the City. The Anaheim Regional Transportation Intermodal Center (ARTIC) and
Anaheim Canyon Metrolink Station also connect the City regionally to several transportation lines
maintained by Metrolink and Amtrak. The City also maintains several biking and hiking trail
networks within the City.
The City is home to a portion of the Santa Ana River Trail, a multi-use trail complex that runs
alongside the Santa Ana River spanning three counties (Orange, Riverside, and San Bernardino). The
trail spans between the San Bernardino County National Forest to the Pacific Ocean, including
multiple entry points and connecting several regional parks.
2.2.2 Approved Project Characteristics
The approved project is the existing General Plan Circulation Element, as amended, including three
addenda to Environmental Impact Report (EIR) No. 330 and Supplemental Environmental impact
Report (SEIR) No. 346.
2.3 PROPOSED PROJECT
The City is proposing amendments to the General Plan Circulation Element including the Bicycle
Master Plan. The General Plan Circulation Element would be revised in order to resolve
inconsistencies with existing conditions within the City of Anaheim and provide consistency with the
MPAH, as conditionally amended. The Bicycle Master Plan would be revised to add a planned Class I
Bike Path on portions of Yorba Linda Boulevard and La Palma Avenue. The proposed project includes
the corresponding revisions to all maps, figures, text, and tables throughout the General Plan to
reflect these changes. This Addendum No. 4 to the Certified EIR compares the potential impacts of
the proposed amendments to the Circulation Element and Bicycle Master Plan with the impacts
identified in the Certified EIR for the approved project. These proposed amendments to the
Circulation Element and Bicycle Master Plan are as follows, depicted in Figures 2.2, Planned Roadway
Network, and 2.3, Planned Bicycle Facilities.
• Yorba Linda Boulevard 2. Yorba Linda Boulevard is currently a six-lane divided facility, with a
small portion which includes a seventh lane in the southbound direction which becomes an SR-
91 merge lane, and is currently classified as a Primary Arterial. The current Primary Arterial
classification supports an ADT up to 30,000 at LOS C and is typically for six-lane facilities with no
parking or four-lane facilities with left-turn pockets and two parking lanes. The Major Arterial
classification applies to roadways that connect to freeways and typically have six-lanes, a
landscaped median, left-turn pockets, and parking lanes.
2 Yorba Linda Boulevard becomes Weir Canyon Road south of SR-91.

• The amendment would include the following actions:
○ Reclassify Yorba Linda Boulevard from the SR-91 eastbound on-ramp on the south to La
Palma Avenue on the north from a Primary Arterial to a Major Arterial in order to match the
existing condition of the roadway. The Scenic Expressway designation would remain in place
beginning south of the SR-91 interchange on Weir Canyon Road; and
○ Add a planned Class I Bike Path on the east side of Yorba Linda Boulevard. The Class I Bike
Path would stretch between La Palma Avenue on the north and Old Canal Road on the
south.
• Savi Ranch Parkway. Savi Ranch Parkway is currently a four-lane divided facility within the City.
The Primary Arterial classification typically applies to four-lane divided facilities with left turn
pockets and parking lanes. The amendment would include the following action:
○ Add Savi Ranch Parkway from the City’s boundary line at Yorba Linda Boulevard to Crystal
Drive and Pullman Street as a Primary (four-lane, divided) Arterial to match the existing
condition of the roadway.
• Crystal Drive/Pullman Street/Old Canal Road. Crystal Drive, Pullman Street and Old Canal Road
are currently two-lane divided facilities that provide a loop connection from each end of Savi
Ranch Parkway. There are no through movements at the Savi Ranch Parkway/Yorba Linda
Boulevard intersection, as this intersection only provides left- and right-turn lanes from both
eastbound and westbound Savi Ranch Parkway onto Yorba Linda Boulevard. Therefore, Crystal
Drive, Pullman Street, and Old Canal Road function as a couplet to route travelers to either side
of Yorba Linda Boulevard.3 The City’s Circulation Element currently does not identify Crystal
Drive, Pullman Street/ Old Canal Road on the Planned Roadway Network or provide a
classification for this roadway. The amendment would include the following actions:
○ Add Crystal Drive, Pullman Street/Old Canal Road classified as Collector Streets (two-lane,
divided) in order to provide a classification consistent with the existing configuration of the
roadway.
• La Palma Avenue. This portion of La Palma Avenue is classified as a Secondary Arterial, and no
changes are proposed to the Roadway classification. The amendment would include the
following action:
○ Add a planned Class I Bike Path on the south side of La Palma Avenue between Yorba Linda
Boulevard on the west and the City boundary on the east.
2.4 PROJECT OBJECTIVES
The proposed project would result in minor amendments to the City’s General Plan Circulation
Element including the Bicycle Master Plan, which would be generally consistent with the goals and

objectives established for the approved project. Under the approved project, the City established
the following intended project objectives for the General Plan Update in 2004:
• Provide a comprehensive update to the City’s General Plan and Zoning Code to deal more
effectively with contemporary issues facing the City of Anaheim.
• Provide for a wide range of housing opportunities in close proximity to existing and future
employment centers, and transportation facilities, consistent with the needs identified within
the City's Housing Element and local and regional jobs/housing balance policies.
• Preserve single-family residential neighborhoods by discouraging further development of
multiple family land uses in such areas.
• Concentrate and enhance commercial uses in strategic locations, primarily at the City’s major
intersections.
• Identify potential locations for enhanced entryways into neighborhoods and gateways into the
City.
• Revitalize neighborhood edges by converting underutilized mid-block commercial uses to
housing opportunities and/or community amenities.
• Expand park, open space, and recreational opportunities within the City.
• Intensify the development potential of The Platinum Triangle.
• Create a pedestrian-friendly, active Downtown that reflects the historic character of the
Anaheim Colony.
• Create gathering places where residents, employees, and visitors can interact, socialize, and
recreate.
• Update the City’s Land Use Map to reflect more accurate data provided by a parcel-based GIS
mapping system.
The City established the following objectives for the Housing Opportunities Sites Rezoning Project:
• Provide for the implementation of the Housing Element’s Housing Production Strategy 1V, to
rezone properties identified as Housing Opportunities Sites in the 2006–2014 General Plan
Housing Element and amend the Mixed-Use Overlay Zone, in order to facilitate “by right”
housing development at these locations.
• Facilitate future use of the Statutory Infill Housing Exemption and Senate Bill (SB) 226
streamlining allowed under the California Environmental Quality Act (CEQA) by providing
updated community level environmental review.

• Provide an update of General Plan Land Use Element Table LU-5: Residential Build-Out Estimates
and Table LU-6: Non-Residential Build-Out Estimates to reflect all General Plan amendments
that have been adopted since the City’s General Plan was adopted in May 2004.
In addition to the project objectives of the approved project, the Circulation Element including the
Bicycle Master Plan also contains numerous goals, implementation strategies, and policies to
enhance the development and maintenance of the transportation systems and to maximize
movements for all users within the City. The following policies identified in the Circulation Element
are applicable to the proposed project:
Policy 1 of Goal 1.1: Assign street classifications to provide an acceptable level of service based
on projected traffic demands, circulation functions and the areas they are
intended to serve. The system will be coordinated with the OCTA Master
Plan of Arterial Highways and the circulation plans of adjacent cities.
Policy 1 of Goal 7.1: Provide safe, direct, and continuous bicycle routes for commuter and
recreational cyclists.
Policy 6 of Goal 7.1: Implement a bikeway system with linkages to routes in neighboring
jurisdictions and regional bicycle routes.
Furthermore, the City has established the following objectives for the proposed project:
• Classify arterials consistent with the current configuration of the roadways; and
• Ensure consistency of the General Plan Circulation Element with the OCTA Master Plan of
Arterial Highways (MPAH), as amended, in order to ensure consistency amongst adopted
planning documents and compete for Regional Capacity Program funding for future
improvements; and
• Identify planned bicycle infrastructure in the Circulation Element including the Bicycle Master
Plan to facilitate increased opportunities for funding.
2.5 DISCRETIONARY ACTIONS
Discretionary approvals required for the proposed project include the following:
1. Approval of a General Plan Amendment to amend the Circulation Element including the Bicycle
Master Plan for portions of Yorba Linda Boulevard, Crystal Drive, Pullman Street, Old Canal
Road, Savi Ranch Parkway, and La Palma Avenue for consistency with existing conditions and
MPAH and add planned bicycle infrastructure; and revise maps, figures, text, and tables
throughout the General Plan to reflect these changes.
2. Determine that Program Environmental Impact Report No. 330 (EIR No. 330), Supplemental
Environmental Impact Report No. 346 (SEIR No. 346), and subsequent addenda adequately
analyzed the above General Plan Amendment pursuant to the requirements of CEQA.

3.0 COMPARATIVE EVALUATION OF ENVIRONMENTAL IMPACTS
The following discussion contains an analysis of the potential impacts of the changes to the
approved project in relation to the proposed project. The potential impacts of the proposed project
are compared to impacts identified for the approved project analyzed in the Certified EIR. As
previously explained in Chapter 1.0, Introduction, this comparative analysis has been undertaken
pursuant to CEQA and to provide City decision-makers with a factual basis for determining whether
the proposed changes to the approved project, changes in circumstances, or new information since
the certification of the Certified EIR require additional environmental review. Potential impacts
associated with the proposed project are evaluated using the same thresholds applied in the
Certified EIR. The basis for each finding is explained in the analysis that follows.
IMPACTS IDENTIFIED IN THE CERTIFIED EIR
As discussed in Chapter 2.0, Project Description, the proposed project would result in minor
amendments to the City’s General Plan Circulation Element and the Bicycle Master Plan. The
proposed project would include updates to the Circulation Element of the General Plan, which were
already analyzed under the approved project and any impacts are anticipated to be similar to or less
than those impacts previously covered by the Certified EIR. Additionally, the proposed project would
include updates to the Bicycle Master Plan that have not been analyzed by the approved project but
would not be considered significant. Environmental impacts of the proposed updates to the Bicycle
Master Plan were evaluated in the City of Yorba Linda IS/MND, and these findings were considered
in the analysis provided below. Although impacts would be similar to or less than those previously
covered by the Certified EIR, a new analysis for impacts is provided in this Addendum as required by
CEQA. The environmental analysis provided in the Certified EIR remains relevant and applicable to
the proposed project in areas unaffected by changes in existing conditions and changes in the
proposed project for the environmental topics as listed below.
The City had determined in EIR No. 330 that the following issues would have less than significant or
no impacts and would therefore not be addressed: aesthetics, agricultural and forestry resources,
land use/planning, mineral resources, population/housing, and recreation. In addition, SEIR No. 346
concluded potential impacts to these environmental topics, as well as, biological resources, cultural
resources, geology/soils, hazards and hazardous materials, hydrology/water quality, public services,
and utilities and service systems would not be significantly impacted compared to the impacts
identified in EIR No. 330; however, these topics were all addressed in the Initial Study prepared for
SEIR. No 346. Refer to Sections 3.1 through 3.10 below for a discussion of the environmental topic
areas that included potentially significant impacts in the Certified EIR.
• Aesthetics. The Certified EIR determined that impacts to aesthetic and scenic resources would
be less than significant. Sources of light and glare within the Planning Area are associated with
buildings (interior and exterior), security lighting, sign illumination, parking area lighting, and
sports fields. These sources are mostly associated with the residential, commercial, industrial,
and recreational uses located throughout the City. Other sources of nighttime light include
streetlights and vehicular traffic along roadways. Additionally, ambient lighting comes from
surrounding communities and roadways. The Certified EIR determined that the approved
project would result in improvements to the visual character of the City through

implementation of the General Plan and Zoning Code Updates. In addition, buildout of the
housing opportunities sites would be consistent with the buildout anticipated in the General
Plan, and no additional impacts were identified. The conditions of the Planning Area have not
changed since the Certified EIR. The proposed project would reclassify existing roadways and
does not include or facilitate physical improvements that would alter the Planning Area’s
aesthetic or scenic resources. As the proposed reclassifications would be consistent with the
existing configurations of the roadways within the Planning Area, these updates to the
Circulation Element would not facilitate future expansion of capacity or development that would
result in additional vehicular traffic or related light and glare impacts from parked cars or
headlights. Addition of the two bike paths would also not substantially affect the existing visual
environment along Yorba Linda Boulevard or La Palma Avenue given the location of the paths
adjacent to existing roadways. Therefore, like the approved project, the proposed project would
not result in any impacts to aesthetic resources, and the conclusions of the Certified EIR remain
valid.
• Agricultural Resources. The Certified EIR determined that there would be no impacts to
agricultural resources. The majority of the City is built out and does not have any large areas
that are currently in agricultural production. However, the General Plan continues to allow use
of easements for limited agricultural production including nursery crops. The proposed rezoning
for housing opportunities did not include redesignation of any agricultural areas or areas that
contained forestry resources. Similarly, the proposed project would not change the land use
designation for any parcels and would not result in any land use changes or physical
development that may impact the agricultural operations of these parcels. Furthermore, the
conditions of the Planning Area have not changed since the Certified EIR. Therefore, similar to
the approved project, the proposed project would not result in any impacts to agricultural
resources, and the conclusions of the Certified EIR remain valid.
• Land Use and Planning. The Certified EIR determined that the approved project would not result
in significant impacts to land use and planning. The analysis of land use and planning impacts in
EIR No. 330 concluded that upon implementation of regulatory requirements and General Plan
goals and policies, buildout of the General Plan would not result in significant impacts related to
land use and planning policies in the Planning Area. In addition, because EIR No. 330
contemplated development of the housing opportunity sites for residential and mixed uses, and
the rezoning was proposed to provide consistency with the land uses in the adopted General
Plan, impacts were also considered less than significant in SEIR No. 346. The proposed project
would update the Circulation Element of the General Plan by reclassifying roadways consistent
with existing conditions and does not include any physical improvements and would add two
Class I Bike Paths to the Bicycle Master Plan. The proposed changes to the roadway
classifications would not alter the land use designations of the General Plan. The conditions of
the Planning Area have not changed since certification of EIR No. 330. Therefore, like the
approved project, the proposed project would not result in any impacts to land use and
planning, and the conclusions of the Certified EIR remain valid.
• Mineral Resources. The Certified EIR determined that the approved project would not result in
significant impacts to mineral resources. While EIR No. 330 identified three specific areas of
regionally significant mineral resources within the City, it concluded that the land use
designations specified in the General Plan Update would not conflict with operation of these
mines. Furthermore, because EIR No. 330 contemplated development of the housing

opportunity sites, impacts to mineral resources were also considered less than significant in SEIR
No. 346. The proposed project would update the Circulation Element of the General Plan by
reclassifying roadways consistent with existing conditions, would add two Class I Bike Paths to
the Bicycle Master Plan, and does not propose any physical improvements. The conditions of the
Planning Area have not changed since the Certified EIR, and no changes to land use designations
or physical development would occur as a result of project implementation. Therefore, similar
to the approved project, the proposed project would not result in any impacts to mineral
resources, and the conclusions of the Certified EIR remain valid.
• Population and Housing. The Certified EIR determined that the approved project would not
have any significant impacts on population and housing resources. The City’s population would
grow as a result of the approved project; however, this growth would not occur at a large
enough scale to meet a threshold of significance and the General Plan Update was considered
consistent with the City’s commitments to provide housing to meet anticipated future demands
and population increases. As the rezoning analyzed in SEIR No. 346 involved rezoning for
consistency with the land use designations adopted in the General Plan Update, SEIR No. 346
concluded that impacts would remain less than significant. The proposed project would not alter
any land uses designations or propose physical development, there would be no displacement
of existing housing or people. As the reclassifications would update the Circulation Element to
be consistent with existing conditions and would add two Class I Bike Paths to the Bicycle
Master Plan, the proposed project would not result in additional capacity and would not induce
growth or alter any population projections and housing resources beyond what was anticipated
in the Certified EIR. Similar to the approved project, the proposed project would not result in
any impacts to population and housing, and the conclusions of the Certified EIR remain valid.
• Recreation. The Certified EIR determined that the approved project would not have any
significant impacts on recreation resources. The City has extensive parks and recreation
facilities. The City owns and operates nearly 50 developed parks totaling almost 700 acres, and
has over 50 miles of developed and proposed riding and hiking trails. The approved project
included the adoption of the Green Element and the Certified EIR concluded that
implementation of the goals and policies outlined in this element and compliance with the City’s
park dedication ordinance would adequately address impacts to recreation resources. As the
rezoning analyzed in SEIR No. 346 involved rezoning for consistency with the land use
designations adopted in the General Plan Update, SEIR No. 346 concluded that impacts would
remain less than significant. The conditions of the Planning Area have not changed since the
Certified EIR. The reclassification of roadways would not involve any physical improvements and
would not alter any recreation resources. As the proposed project would update the Circulation
Element to be consistent with existing conditions, the proposed project would not result in
additional capacity and would not induce growth resulting in the need for construction of new
or the expansion of existing recreational resources. The addition of the two Class I Bike Paths to
the Bicycle Master Plan would provide additional recreational resources within the City;
however, the proposed project does not propose physical improvements. Therefore, like the
approved project, the proposed project would not result in any impacts to recreation.

IMPACTS NOT IDENTIFIED IN THE CERTIFIED EIR
Impacts related to energy, wildfire, and tribal cultural resources were not evaluated as individual
resource topics in the Certified EIR because, at the time of preparation, these topics were not
required as individual resource sections under State CEQA Guidelines Appendix G. Tribal cultural
resources was added as a resource category in State CEQA Guidelines Appendix G in 2015. The
energy and wildfire resource categories were added to State CEQA Guidelines Appendix G in 2019.
As these three resource categories were only included in the State CEQA Guidelines after the 2004
Certified EIR and the 2013 SEIR were approved, they were not evaluated as separate resource
sections in the Certified EIR. Prior to the updates made to these topics in 2015 and 2019, impacts
from wildfire were briefly discussed within the Hazards and Hazardous Materials section, and
impacts to tribal cultural resources were briefly discussed within the Cultural Resources section. Per
the discussion below, the proposed project would not result in significant impacts to the following
issues; energy, wildfire, and tribal cultural resources.
• Energy. The proposed project is a policy-level document to update the City’s Circulation Element
for the reclassification of roadways in order to resolve inconsistencies with existing conditions
within the City, update the Bicycle Master Plan to add Class I Bike Paths, and provide
consistency with the MPAH, as amended. As the proposed reclassification and added bike paths
would not increase energy demand, there would be no significant impacts related to energy
resources.
• Wildfire. Per discussion in the Hazards and Hazardous Materials section of the 2004 EIR No. 330,
it was concluded that wildland fires would pose a significant threat to people and structures as
the Hill and Canyon Area is susceptible as a result of its larger proportion of vegetation and open
space. In wildland areas, proper precautions, such as the use of fire-resistant building materials,
would protect developed lands from fires and, therefore, reduce the potential loss of life and
property. The approved project includes goals and policies that address the threat of wildland
fires within the City, and impacts would be less than significant. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, impacts
related to wildfires resulting from the rezoning would remain less than significant. The proposed
project does alter the anticipated development analyzed under the approved project. The
proposed project is a policy-level document to update the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within
the City, update the Bicycle Master Plan to add Class I Bike Paths, and provide consistency with
the MPAH, as amended. As the proposed reclassification and added bike paths would not alter
the land use designations of the approved project, there would be no changes to the impacts
previously identified. Therefore, the proposed project would not result in significant impacts
related to wildfire.
• Tribal Cultural Resources. As discussed in Section 3.3 Cultural Resources, as the proposed
project includes an update to the City’s General Plan, the requirements of SB 18 for Native
American Consultation apply. The City submitted a request for a Sacred Lands File search and
letters were sent to 14 tribes on December 10, 2021, to notify them of the proposed project.
Tribes were provided 90 days from receipt of these notification letters to respond and request
consultation. No requests for consultation have been received to date, and the consultation
window closed on March 10, 2022. Therefore, no impacts to tribal cultural resources are

anticipated, and no new significant impacts to cultural resources would occur beyond those
analyzed in the Certified EIR.
3.1 AIR QUALITY
3.1.1 Existing Environmental Setting
No substantial changes to the Planning Area have occurred since the preparation of the Certified
EIR. There have been no major changes to the existing setting of the Planning Area with respect to
air quality.
The Planning Area includes the entire City of Anaheim and is located under the jurisdiction of the
South Coast Air Quality Management District (SCAQMD) and is part of the South Coast Air Basin
(Basin). The SCAQMD reports to the California Air Resources Board (CARB) and all emissions are also
governed by the California Ambient Air Quality Standards (CAAQS) as well as the National Ambient
Air Quality Standards (NAAQS). The Basin is currently designated as nonattainment for ozone (O3)
and particulate matter (PM10 and PM2.5, particulate matter less than 10 microns in diameter and less
than 2.5 microns in diameter, respectively). Emissions of volatile organic compounds (VOC) and
nitrogen oxides (NOX) are precursors to the formation of O3. In addition, NOx is a precursor to the
formation of particulate matter (PM10 and PM2.5).
3.1.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project result in a cumulatively considerable net increase of any criteria pollutant for
which the project region is non-attainment under an applicable federal or state ambient air quality
standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)?
Approved Project
Significant and Unavoidable Impact. As described in the EIR No. 330, construction of future land
uses would generate temporary emissions. Anticipated future development associated with the
approved project would increase short-term construction-generated emissions that have the
potential to exceed the SCAQMD’s significant thresholds. As the scale of future construction
activities is not known, EIR No. 330 determined that maximum daily emissions associated with an
individual development project would be potentially significant, and mitigation would be required.
Implementation of the SCAQMD’s rules, regulations, and Mitigation Measures 5.2-1 through 5.2-6,
provided in EIR No. 330, would reduce this impact, but not to a less than significant level, and air
quality impacts were determined to be significant and unavoidable. Similarly, SEIR No. 346
concluded that, like the 2004 approved project, due to the scale of development activity associated
with General Plan buildout, emissions may exceed the SCAQMD’s significance thresholds and
cumulatively contribute to the nonattainment designations of the Basin. The Certified EIR concluded
that impacts would remain significant and unavoidable after mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would neither allow for any increase in the capacity of these
roadways nor propose future development that would produce emissions of criteria air pollutants
and precursor pollutants. Therefore, there would be no change in the criteria air pollutants and
precursor pollutants from construction activities for which the region is in nonattainment compared
to the approved project. Therefore, the conclusions of the Certified EIR remain valid.
Would the project conflict with or obstruct implementation of the applicable air quality plan?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that as long as growth projections included in
the 2003 Air Quality Management Plan (AQMP) are not exceeded by implementation of the General
Plan Update and AQMP reduction measures are included, then the approved project would be
consistent with the region’s applicable air quality plan. Future development consistent with the
approved project may result in significant regional air quality impacts, and mitigation would be
required at the project level. However, the approved project is consistent with the AQMP and other
regional plan strategies to reduce the number of trips and length of trips in the region, and to
improve the balance between jobs and housing at the subregional level. Therefore, impacts were
considered less than significant. Similarly, SEIR No. 346 concluded the proposed zone changes were
consistent with the adopted General Plan and were assumed in the 2007 and 2012 AQMPs. Impacts
were also considered less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would not allow for any increases in the capacity of these roadways or
increase trips in the region. The proposed project, therefore, would not conflict with or obstruct
implementation of the AQMP for the Planning Area compared to the approved project. Therefore,
the conclusions of the Certified EIR remain valid.
Would the project violate any air quality standard or contribute substantially to an existing or
projected air quality violation?
Approved Project
Significant and Unavoidable Impact. EIR No. 330 concluded that the approved project had the
potential to result in new development within the Planning Area, which could include short-term,
construction sources of toxic air contaminants (TACs) and long-term, operational sources of TACs.
Subsequent CEQA documentation prepared for individual projects would have project-specific data
and would be required to address, and if necessary, mitigate any potentially significant impacts to a
less than significant level. EIR No. 330 also concluded that development within the Planning Area

could place sensitive land uses proximate to intersections that could exceed these standards in the
near term, and this impact was considered significant. SEIR No. 346 concluded that the proposed
zone changes would exceed SCAQMD’s thresholds for all criteria pollutants including carbon
monoxide (CO) and would result a substantial increase in emissions compared to the analysis in EIR
No. 330 for the same criterial air pollutants. Construction and operation emissions were considered
to be significant and unavoidable.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document to update the City’s Circulation Element for
the reclassification of roadways in order to resolve inconsistencies with existing conditions, amend
the Bicycle Master Plan to include two new Class I Bike Paths within the City, and provide
consistency with the MPAH, as amended. The proposed project would neither allow for any increase
in the capacity of these roadways nor propose future development; therefore, the proposed project
would not violate air quality standards or contribute to projected air quality violations. However, as
the proposed project would not alter the land use designations or development assumptions of the
approved project, the proposed project would also not reduce the significant and unavoidable
impacts identified for the approved project, and the conclusions of the Certified EIR remain valid.
Would the project expose sensitive receptors to substantial pollutant concentrations?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that sensitive
land uses may be sited near major freeways and expose receptors to substantial pollutant
concentrations but concluded that impacts would be less than significant because the criterion to
evaluate land use compatibility was not established and subsequent CEQA documentation would be
prepared for individual projects. The 2005 CARB guidance addressed the siting of sensitive land uses
in the vicinity of freeways, and new health analysis was conducted for SEIR No. 346, which
implemented a new mitigation measure requiring property owners/developers to submit a health
risk assessment (HRA) prior to issuance of building permits for projects with the potential to expose
sensitive receptors to substantial pollutant concentrations. With adherence to this mitigation
measure, air quality land use compatibility impacts were considered to be less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document to update the City’s Circulation Element for
the reclassification of roadways in order to resolve inconsistencies with existing conditions within
the City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide
consistency with the MPAH, as amended. The proposed project would not expose sensitive
receptors to substantial pollutant concentrations. As the proposed project would not alter the land
use designations of the adopted General Plan, there would be no changes to placement of sensitive
land uses proximate to major sources of air pollution. Therefore, the conclusions of the Certified EIR
remain valid.

Would the project create objectionable odors affecting a substantial number of people?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that there were no major existing sources of
odors identified in the Planning Area to which occupants would be exposed on a frequent basis.
However, commercial development may include odor-emitting sources. Temporary construction-
generated odors such as the use of diesel-powered equipment disperses rapidly with increased
distance from the source. If new development is proposed near residences or sensitive receptors,
the development projects would be required to evaluate and mitigate potential impacts. Therefore,
impacts were considered less than significant. SEIR No. 346 concluded that the rezoning generally
proposed the same types of land uses assumed for these sites as the adopted General Plan, none of
which would generate offensive odors affecting substantial numbers of people or would have a
significant impact related to the creation of objectionable odors. Impacts were considered less than
significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document to update the City’s Circulation Element for
the reclassification of roadways in order to resolve inconsistencies with existing conditions, amend
the Bicycle Master Plan to include two new Class I Bike Paths within the City, and provide
consistency with the MPAH, as amended. As the proposed project would neither allow for any
increase in the capacity of these roadways nor propose future development, the proposed project
would not create objectionable odors. As the proposed project would not alter the land use
designations of the adopted General Plan, there would be no changes to placement of land uses
that generate odors that may affect a substantial number of people. Therefore, the conclusions of
the Certified EIR remain valid.
3.1.3 Cumulative Air Quality Impacts
Approved Project
Cumulatively Considerable Impact. The Certified EIR analyzed the Basin as the cumulative study
area for potential air quality impacts. All future projects in the Basin would be required to comply
with SCAQMD rules and regulations and are subject to independent review. EIR No. 330 concluded
that due to the regional growth anticipated with General Plan buildout, the cumulative emissions
scenario would be considered significant and unavoidable. In addition, since the combination,
number, and sizes of projects that could be under construction at any one time are unknown, even
with implementation of the mitigation measures provided in the Certified EIR, the approved project
would result in significant cumulative construction emissions. Cumulative impacts for odors
affecting a substantial number of people were determined to be less than significant following
compliance with odor policies enforced by the SCAQMD (including Rule 402).
Proposed Project
Implementation of the proposed project would not result in changes in cumulative air quality
impacts. The proposed project is a policy-level document that would not result in changes to the
existing land uses or development assumptions included under the approved project. Therefore, the

proposed project would not have a significant impact on cumulative air quality impacts, and the
conclusions of the Certified EIR remain valid.
3.1.4 Findings Related to Air Quality
3.1.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to air quality, and there would not be an increase in the
severity of impacts described in the Certified EIR.
3.1.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
air quality that would require major changes to the Certified EIR.
3.1.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time of the Certified EIR, indicating that a new significant
effect not reported in that document may occur. Based on the information and analyses above,
there is no substantial new information indicating that there would be a new significant impact
related to air quality requiring major revisions to the Certified EIR.
3.1.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to air quality identified and
considered in the Certified EIR.
3.1.5 Mitigation Measures
The mitigation measures from the Certified EIR pertaining to air quality are not applicable to the
proposed project, as they include requirements for future development projects. As the proposed
project does propose physical development, the mitigation measures do not apply.

3.2 BIOLOGICAL RESOURCES
3.2.1 Existing Environmental Setting
The City of Anaheim is largely urbanized and surrounded by other developed cities with few
remaining areas of natural habitat. Developed areas of the City contain non-native species of plants
and animals while the eastern Hill and Canyon Area contains the majority of the City’s remaining
significant biological resources. A State-owned 1,400-acre wildlife corridor is present within Coal
Canyon. The General Plan and Zoning Code Update reflects this use by designating this area for open
space purposes. The other significant biological resource located in the City is the Santa Ana River.
3.2.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project have a substantial or adverse effect, either indirectly or through habitat
modifications, on any species identified as a candidate, sensitive, or special status species in local or
regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S.
Fish and Wildlife Service?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that the Hill and
Canyon Area provides important foraging, dispersal, migratory, and wildlife corridors for many
sensitive species. Implementation of development consistent with the approved project would
result in both direct and indirect significant adverse impacts to wildlife. Goals and policies included
in the approved project, in addition to Mitigation Measures 5.3-1 through 5.3-7, provided in EIR
No. 330, would reduce localized impacts of development on biological resource for projects within
sensitive plant communities and wildlife corridors and/or for projects containing sensitive wildlife
species. SEIR No. 346 concluded that because EIR No. 330 contemplated development of the
housing opportunity sites, impacts to biological resources resulting from the rezoning would remain
less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. As the proposed project would not allow for any increase in the
capacity of these roadways or impact sensitive resources, the proposed project would not have the
potential to adversely affect sensitive species, either directly or indirectly. The proposed project is a
policy-level document and would not alter the land use designations of the adopted General Plan,
there would be no changes to the designation of land uses preserved for the protection of sensitive
species or changes to the impacts previously identified for buildout of the General Plan under the
approved project. Therefore, the conclusions of the Certified EIR remain valid.
Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations or by the California Department
of Fish and Wildlife or the U.S. Fish and Wildlife Service?

Approved Project
Less Than Significant Impact with Mitigation Incorporated. Areas along the Santa Ana River and in
the eastern portion of the City were identified to contain riparian habitat and EIR No. 330 concluded
that the General Plan buildout would have potential impacts on existing riparian areas. Mitigation
Measure 5.3-8, provided in EIR No. 330, would require compliance with the United States Army
Corps of Engineers (USACE) and California Department of Fish and Wildlife (CDFW) and permit
processes at the project level to minimize the impacts of development. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, impacts to
riparian habitat resulting from the rezoning would remain less than significant with mitigation
incorporated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not allow for any increase in the capacity of these roadways
or impact riparian habitat, the proposed project would not have the potential to adversely affect
riparian habitat. As the proposed project would not alter the development assumptions of the
adopted General Plan, there would be no changes to the impacts previously identified, and the
conclusions of the Certified EIR remain valid.
Would the project have a substantial adverse effect on federally protected wetlands as defined by
Section 404 of the Clean Water Act (including but not limited to, marsh, vernal pool, coastal, etc.)
through direct removal, filling, hydrological interruption, or other means?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. Potential impacts to riparian or
wetlands protected by Section 404 of the Clean Water Act as a result of the future development
anticipated with General Plan buildout would be mitigated through compliance with the regulations
of the USACE and mitigation measures at the project level would minimize impacts of development.
SEIR No. 346 concluded that because EIR No. 330 contemplated development of the housing
opportunity sites, impacts to federally protected wetlands resulting from the rezoning would remain
less than significant with mitigation incorporated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

impact wetlands, the proposed project would not have the potential to adversely affect federally
protected wetlands. As the proposed project would not alter the development assumptions of the
approved project, there would be no changes to the impacts previously identified and the
conclusions of the Certified EIR remain valid.
Would the project interfere substantially with the movement of any native resident or migratory fish
or wildlife species or with established native resident or migratory wildlife corridors, or impede the
use of native wildlife nursey sites?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that several
areas within the City are utilized as migratory corridors for wildlife. Future development within the
Hill and Canyon Area could include the placement of bridges, an increase in vehicular traffic levels,
and an increase in nighttime light levels, which may deter the movement of wildlife. Through
adherence to the City’s Green Element goals and policies related to conservation of biological
resources, compliance with local and State regulations, and implementation of Mitigation Measure
5.3-9, provided in EIR No. 330, requiring a project-level biological resources analysis, impacts would
be reduced to less than significant. SEIR No. 346 concluded that because EIR No. 330 contemplated
development of the housing opportunity sites, impacts to wildlife movement resulting from the
rezoning would remain less than significant with mitigation incorporated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not allow for any increase in the capacity of these roadways,
alter the configurations of the roadways, or impact wildlife movement, the proposed project would
not have the potential to interfere with wildlife movement. As the proposed project would not alter
the development assumptions of the approved project, there would be no changes to the impacts
previously identified, and the conclusions of the Certified EIR remain valid.
Would the project conflict with any local policies or ordinances protecting biological resources, such
as a tree preservation policy or ordinance?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that future projects would have to comply with
all relevant policies and ordinances relating to tree preservation, which includes the City of Anaheim
Street Tree Ordinance. Therefore, because these regulations must be implemented for all future
development projects, impacts would be less than significant. SEIR No. 346 concluded that because
EIR No. 330 contemplated development of the housing opportunity sites, the rezoning would also
not conflict with local policies or ordinances, and impacts would remain less than significant.

Would the project conflict with the provisions of an adopted habitat conservation plan, natural
community conservation plan, or other approved local, regional, or state habitat conservation plan?
Approved Project
Less Than Significant Impact. Portions of the City of Anaheim are within the Orange County Central/
Coastal Natural Communities Conservation Plan Subregion (NCCP) and Habitat Conservation Plan
(HCP). EIR No. 330 concluded all new development would be required to adhere to the guidelines of
the NCCP/HCP. Therefore, impacts would be less than significant. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, the rezoning
would not conflict with the NCCP/HCP, and impacts would remain less than significant.
Proposed Project

3.2.3 Cumulative Biological Resources Impacts
Approved Project
Less Than Significant Impact. Despite potential for commercial, residential, and industrial growth in
the Planning Area from implementation of the approved project, EIR No. 330 concluded that
cumulative impacts on biological resources would be less than significant with mitigation
incorporated. New development would mostly be limited to currently developed land, and the goals
and policies of the General Plan for conservation of natural resources along with the
implementation of the NCCP required for all future project development would reduce impacts to
biological resources to a less than significant level. SEIR No. 346 concluded that because EIR No. 330

contemplated development of the housing opportunity sites, the rezoning would not result in
additional impacts to biological resources, and cumulative impacts would remain less than
significant.
Proposed Project
The proposed project does not propose physical development nor does it alter the anticipated
development under the approved project. The proposed project is a policy-level document that
would not result in changes to the existing land uses or development assumptions under the
approved project. Therefore, the proposed project would not result in cumulatively considerable
impacts on biological resources, and the conclusions of the Certified EIR remain valid.
3.2.4 Findings Related to Biological Resources
3.2.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to biological resources, and there would not be a
substantial increase in the severity of impacts described in the Certified EIR.
3.2.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
biological resources that would require major changes to the Certified EIR.
3.2.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time the Certified EIR was certified, indicating that a new
significant effect not reported in that document may occur. Based on the information and analyses
above, there is no substantial new information indicating that there would be a new significant
impact related to biological resources requiring major revisions to the Certified EIR.
3.2.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to biological resources identified and
considered in the Certified EIR.
3.2.5 Mitigation Measures
The mitigation measures from the Certified EIR pertaining to biological resources are not applicable
to the proposed project, as they include requirements for future development projects. As the
proposed project does not propose physical development, the mitigation measures do not apply.

3.3 CULTURAL RESOURCES
3.3.1 Existing Environmental Setting
Archaeological sites are locations that contain significant evidence of human activity and are often
located along creek areas, ridgelines, and vistas. Many of these types of landforms are located
within the City, and one major cultural resource site (CA-ORA-303) has been identified and
registered adjacent to SR-91. Paleontological sites are those areas that show evidence of pre-human
activity. Areas with Moderate to High paleontological sensitivity ratings have been identified
throughout areas of the Hill and Canyon Area.
3.3.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project cause substantial adverse change in the significance of a historical resource as
identified in §15064.5 of the CEQA Guidelines and/or identified on the Qualified Historic Structures
list of the Anaheim Colony Historic District Preservation Plan?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. Historic structures and sites that are
eligible for the National Register of Historic Places listing, particularly in the Anaheim Colony area,
may be vulnerable to development activities accompanying revitalization. EIR No. 330 concluded
that the policies of the General Plan Community Design Element would continue to enhance its
historic buildings and districts. With adherence to the goals and policies included in the General Plan
Update, and implementation of Mitigation Measure 5.4-1, provided in EIR No. 330, requiring
property owners and developers to provide studies to document the presence or absence of historic
resources for areas with documented or inferred resource presence, impacts to cultural resources
would be less than significant. SEIR No. 346 concluded that because EIR No. 330 contemplated
development of the housing opportunity sites, the rezoning would also require compliance with
General Plan policies and Mitigation Measure 5.4-1 for future projects, and impacts would remain
less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not allow for any increase in the capacity of these roadways,
alter the configurations of the roadways, propose future development, or impact a historical
resource, the proposed project would not have the potential to cause a substantial adverse change
to the significance of a historical resource. As the proposed project would not alter the development
assumptions of the approved project, there would be no changes to the impacts previously
identified, and the conclusions of the Certified EIR remain valid.

Would the project cause substantial adverse change in the significance of an archaeological resource
pursuant to §15064.5 of the CEQA Guidelines, directly or indirectly destroy a unique paleontological
resource or site or unique geologic feature, or disturb any human remains, including those interred
outside of formal cemeteries?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that CEQA
review and mitigation would be required for projects subject to discretionary action, particularly for
archaeological resources. Mitigation Measures 5.4-2 and 5.4-3, provided in EIR No. 330, would
require project-level studies and mitigation for impacts to archaeological or paleontological
resources, and impacts to cultural resources would be less than significant. SEIR No. 346 concluded
that because EIR No. 330 contemplated development of the housing opportunity sites, the rezoning
would also require compliance with Mitigation Measures 5.4-2 and 5.4-3, and impacts would remain
less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not allow for any increase in the capacity of these roadways
or affect archaeological resources, the proposed project would not have the potential to cause a
substantial adverse change to the significance of archaeological or paleontological resources. As the
proposed project would not alter the development assumptions of the approved project, there
would be no changes to the impacts previously identified and the conclusions of the Certified EIR
remain valid.
Furthermore, as the proposed project includes an update to the City’s General Plan, the
requirements of SB 18 for Native American Consultation apply. The City submitted a request for a
Sacred Lands File search and letters were sent to 14 tribes on December 10, 2021, to notify them of
the proposed project. Tribes were provided 90 days from receipt of these notification letters to
respond and request consultation. No requests for consultation have been received to date, and the
consultation window closed on March 10, 2022. Therefore, no impacts to tribal cultural resources
are anticipated, and no new significant impacts to cultural resources would occur beyond what was
analyzed in the Certified EIR.
3.3.3 Cumulative Cultural Resources Impacts
Approved Project
Less Than Significant Impact. Despite potential for commercial, residential, and industrial growth in
the Planning Area from the approved project, EIR No. 330 concluded that impacts to cultural
resources would be site specific and that potential impacts would be mitigated at the project level.
Goals and policies included in the approved project would address potential impacts to cultural
resources from future projects, and cumulative impacts to cultural resources were anticipated to be

less than considerable and less than cumulatively significant. SEIR No. 346 concluded that because
EIR No. 330 contemplated development of the housing opportunity sites, the rezoning would also
require compliance with the City’s General Plan goals and policies for future projects, and impacts
would remain less than cumulatively considerable.
Proposed Project
The proposed project does not propose physical development nor does it alter the anticipated

3.3.4 Findings Related to Cultural Resources
3.3.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to cultural resources, and there would not be a substantial
increase in the severity of impacts described in the Certified EIR.
3.3.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or

This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time of the Certified EIR, indicating that a new significant
effect not reported in that document may occur. Based on the information and analyses above,
there is no substantial new information indicating that there would be a new significant impact
related to cultural resources requiring major revisions to the Certified EIR.
3.3.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to cultural resources identified and
considered in the Certified EIR.
3.3.5 Mitigation Measures
The mitigation measures included in the Certified EIR pertaining to cultural resources are not
applicable to the proposed project, as they include requirements for future development projects.
As the proposed project does not propose any physical development, these requirements and
mitigation measures do not apply.

3.4 GEOLOGY AND SOILS
3.4.1 Existing Environmental Setting
The City of Anaheim is situated in the Peninsular Ranges Geomorphic Province, extending
approximately 900 miles from the Transverse Ranges and the Los Angeles Basin, south to the
southern tip of Baja California. The province generally consists of a northwest-southeast oriented
complex of blocks separated by similarly trending faults. The broad alluvial plain area in the western
half of the City is generally mantled by Holocene age (up to 11,000 years old) alluvial deposits, which
become increasingly older with depth. In addition, Pleistocene age (11,000 to 2,000,000 years old)
terrace deposits are present along the upper edges of the alluvial plains and the lower benches of
hillside areas. The Santa Ana River channel area is also underlain by Holocene alluvial deposits. The
Peralta Hills and Santa Ana Mountains expose a sequence of older sedimentary rock units, which
include Tertiary to Cretaceous age (2 million to 135 million years old) marine and non-marine
deposits. Landslide deposits are also relatively common in the steeper hillside areas.
3.4.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project expose people or structures to potential or substantial adverse effects, including
risk of loss, injury, or death involving: i) rupture of a known earthquake fault, ii) strong seismic
ground shaking; iii) seismic-related ground failure, including liquefaction; or iv) landslides?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded there are no
areas of the City on an Alquist-Priolo Earthquake Fault Zoning Map; however, buildout of the
General Plan would have the potential to expose future residents to the effects of geological
hazards, including groundshaking, seismically induced surface rupture, liquefaction, and slope
instability leading to mudslides and landslides. Regional active faults are typical of Southern
California; therefore, it is reasonable, to expect a moderately strong ground motion seismic event to
occur with the potential to cause property damage, personal injury, and loss of life. Mitigation
Measure 5.5-1, provided in EIR No. 330, would require future projects to include a geologic and
geotechnical investigation and compliance with the General Plan goals, policies, existing codes, and
regulations. Therefore, impacts would be reduced to less than significant. SEIR No. 346 concluded
that the rezoning would also require compliance with General Plan policies and Mitigation Measure
5.5-1 for future projects, and impacts would remain less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would not facilitate greater than anticipated future development, the
proposed project would not have the potential to expose people or structures to geologic hazards.

there would be no changes to the impacts previously identified for buildout of the General Plan
under the approved project. Therefore, the conclusions of the Certified EIR remain valid.
Would the project result in substantial soil erosion or the loss of topsoil?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that development would be subject to local
and State requirements for erosion control and grading. In addition, project sites encompassing an
area of one or more acres would require compliance with a National Pollutant Discharge Elimination
System (NPDES) permit and consequently the development and implementation of a Storm Water
Pollution Prevention Plan (SWPPP). With adherence to these regulations and implementation of the
General Plan goals and policies, impacts would be less than significant. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, the rezoning
would also require compliance with NPDES permit requirements and General Plan policies for future
projects, and impacts would remain less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. Design of the Class I Bike Paths would include appropriate best management practices
(BMPs) and would not result in soil erosion. As the proposed project would not alter the
development assumptions of the approved project, there would be no changes to the impacts
previously identified. Therefore, the conclusions of the Certified EIR remain valid.
Would the project be located on a geologic unit or soil that is unstable or that would become
unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading,
subsidence, liquefaction, or collapse?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that isolated areas of the City and its sphere-of-
influence are subject to landslides; however, many of the potential landslides that have existing land
development, may have been removed, mitigated, or altered during grading for land development.
With the established programs, impacts were considered less than significant. SEIR No. 346
concluded that because EIR No. 330 contemplated development of the housing opportunity sites,
the rezoning would also require compliance with the General Plan policies for future projects, and
impacts would remain less than significant with mitigation.

project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

EIR remain valid.
Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building
Code (1994), creating substantial risk to life or property?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that soils throughout the City range from “Low”
to “High” in expansion potential and proposed structures should be designed for the appropriate
expansion potential. Application of the existing regulations identified in the City’s Municipal Code
and Uniform Building Code and grading regulations would minimize the risk associated with any
development proposed within areas containing expansive soils, and impacts would be less than
significant. SEIR No. 346 concluded that because EIR No. 330 contemplated development of the
housing opportunity sites, the rezoning would also require compliance with the City’s regulations for
future projects, and impacts would remain less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved

impacts previously identified. Therefore, the conclusions of the Certified EIR remain valid.
3.4.3 Cumulative Geology and Soils Impacts
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that impacts
relating to geology and soils are site-specific and generally cannot be considered in cumulative
terms. A possible exception would be earthquake hazards. Mitigation of geologic, seismicity, and soil
impacts of development projects would be site specific. The adopted General Plan contains goals,
policies, and actions that address potential impacts due to soils and geology. As such, the approved

project’s contribution to cumulative impacts related to soils and geology is less than considerable
and less than cumulatively significant. SEIR No. 346 concluded that the rezoning would also require
compliance with the General Plan goals and policies for future projects, and impacts would remain
less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document that would not result in changes to the
existing land uses or development assumptions included under the approved project. Therefore, the
proposed project would not result in cumulatively considerable impacts related to geology and soils,
and the conclusions of Certified EIR remain valid.
3.4.4 Findings Related to Geology and Soils
3.4.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to geology and soils, and there would not be a substantial
increase in the severity of impacts described in the 2004 Certified EIR No. 330.
3.4.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
geology and soils that would require major changes to the Certified EIR.
3.4.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time of the Certified EIR, indicating that a new significant
effect not reported in that document may occur. Based on the information and analyses above,
there is no substantial new information indicating that there would be a new significant impact

There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to geology and soils identified and
considered in the Certified EIR.
3.4.5 Mitigation Measures
Mitigation Measure 5.5-1, provided in EIR No. 330, pertaining to geology and soils is not applicable
to the proposed project, as it includes requirements for future development projects. As the
proposed project does propose any physical development, this mitigation measure does not apply.

3.5 GREENHOUSE GAS EMISSIONS
3.5.1 Existing Environmental Setting
EIR No. 330 did not include a discussion of greenhouse gas (GHG) emissions; however, this
discussion was provided in SEIR No. 346 after inclusion of this topic section in the State CEQA
Guidelines Appendix G checklist in 2010. Since preparation of the Certified EIR, there have been no
major changes to the existing setting of the Planning Area with respect to GHG emissions. An
existing GHG emissions inventory of the City was conducted in 2015 for SEIR No. 346 based on the
existing land uses for the sectors of transportation, energy, waste, water, off-road equipment, and
industrial.
3.5.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the 2012 proposed project’s GHG emissions be greater than the 2004 approved project’s GHG
emissions?
Approved Project
Significant and Unavoidable Impact. SEIR No. 346 concluded that GHG emissions for the approved
project would exceed the SCAQMD's proposed GHG efficiency threshold. The rezoning analyzed in
SEIR No. 346 was compared to the General Plan buildout assumed in EIR No. 330 and was
determined to result in a substantial increase in GHG emissions based on SCAQMD’s brightline
thresholds. Due to the magnitude of the increase in GHG emissions for the rezoning compared to
the GHG emissions of the 2004 General Plan buildout scenario, this impact was considered to be
significant. Mitigation Measures 5.2-8 through 5.2-12, provided in EIR No. 330, would reduce GHG
emissions to the extent feasible; however, this impact would remain significant and unavoidable
even after mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would not allow for any increase in the capacity of these roadways or
facilitate future development that would produce GHG emissions. As the proposed project would
not alter the development assumptions of the approved project, there would be no changes to the
impacts previously identified and the conclusions of the Certified EIR remain valid.
Would the proposed project conflict with an applicable plan, policy, or regulation adopted for the
purpose of reducing GHG emissions?
Approved Project
Less Than Significant Impact. SEIR No. 346 concluded that the approved project would be consistent
with the applicable Orange County Sustainable Communities Strategy goals, which were
incorporated into the Southern California Association of Governments’ (SCAG) 2012 Regional

Transportation Plan/Sustainable Communities Strategy (RTP/SCS). SEIR No. 346 also included a
consistency analysis with existing statewide programs adopted for the purpose of reducing GHG
emissions. Compliance with these State and local regulations would ensure that the approved
project would not conflict with the 2008 Scoping Plan. Therefore, with adherence to these local and
regional plans and policies, impacts were determined to be less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would update the Circulation Element to reflect existing conditions,
the proposed reclassification would not allow for any increase in the capacity of these roadways or
facilitate future development or construction. Additionally, the proposed Class I Bike Paths would
not increase capacity of these roadways or facilitate future development. Implementation of the
proposed project would not conflict with or obstruct implementation of the GHG emissions
reduction plan applicable to the Planning Area. Therefore, the conclusions of the Certified EIR
remain valid.
3.5.3 Cumulative Greenhouse Gas Emissions Impacts
Approved Project
Cumulatively Considerable Impacts. SEIR No. 346 concluded that as the GHG emissions for the
approved project would be significant and unavoidable after mitigation and would exceed the
brightline thresholds, impacts would be cumulatively considerable.
Proposed Project
Implementation of the proposed project would not result in changes in cumulative air quality
impacts. The proposed Circulation Element and Bicycle Master Plan updates are policy-level
documents that would not result in development that would contribute to additional GHG
emissions. However, as the proposed project would not alter the development assumptions of the
approved project, there would be no changes to the impacts previously identified, and the
conclusions of the Certified EIR remain valid.
3.5.4 Findings Related to Greenhouse Gas Emissions
3.5.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to GHG emissions, and there would not be a substantial
increase in the severity of impacts described in the Certified EIR.

3.5.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
GHG emissions that would require major changes to the Certified EIR.
3.5.4.3 No New Information Showing Greater Significant Effects than in the Certified EIR
This analysis has analyzed all available relevant information to determine whether there is new
information that was not available at the time the Certified EIR was certified, indicating that a new
significant effect not reported in that document may occur. Based on the information and analyses
above, there is no substantial new information indicating that there would be a new significant
impact to GHG emissions requiring major revisions to the Certified EIR.
3.5.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to GHG emissions identified and
considered in the Certified EIR.
3.5.5 Mitigation Measures
The mitigation measures from the Certified EIR pertaining to GHG emissions are not applicable to
the proposed project, as they include requirements for future development projects. As the
proposed project does not propose any physical development, these mitigation measures do not
apply.

3.6 HAZARDS AND HAZARDOUS MATERIALS
3.6.1 Existing Environmental Setting
There have been no major changes to the existing setting of the Planning Area with respect to
hazards or hazardous materials since the preparation of the Certified EIR. The Planning Area is
developed and contains adequate resources and policy implementation for handling, processing,
transporting, storing, and managing hazardous waste. This also includes adequate processing for
hazardous materials emergency response. Vegetation risk in the undeveloped portions of the Hill
and Canyon Area were estimated to be a moderate probability/high for fire risk.
3.6.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project create a significant hazard to the public or the environment through the routine
transport, use, or disposal of hazardous materials or create a significant hazard to the public or the
environment through reasonable foreseeable upset and accident conditions involving the release of
hazardous materials into the environment?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that there would
be a small increase in residential uses adjacent to railways through the City, which are utilized for
the transport of hazardous materials. In addition, the proposed mixed-use zoning within The
Platinum Triangle and The Colony and Downtown areas would allow for the conversion of industrial
lands and mid-block commercial uses to residential or mixed-use designations. Residential uses are
considered sensitive land uses and may be impacted by any upset or accident involving the release
of hazardous materials. Mitigation Measures 5.6-1 and 5.6-2, provided in EIR No. 330, would ensure
that future development would not result in significant impacts related to hazardous materials. With
adherence to existing ordinances and regulations, and the mitigation measures included for future
development, impacts would be reduced to less than significant levels. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, impacts related
to hazards and hazardous materials resulting from the rezoning would remain less than significant
with mitigation incorporated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would not have the potential to create hazards through the release of
hazardous materials. As the proposed project would not alter the land use designations of the
approved project, there would be no changes to the impacts previously identified. Therefore, the
conclusions of the Certified EIR remain valid.

Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that new school sites required as a result of the
approved project should be evaluated for their proximity and potential exposure to hazardous
materials as they are proposed for development. Future projects involving school site acquisition
must comply with regulations that require that potential hazards to be addressed at the time of site
selection. Compliance with these requirements will prevent any significant hazard impacts related to
the siting of new schools. SEIR No. 346 concluded that because EIR No. 330 contemplated
development of the housing opportunity sites, impacts to hazards and hazardous materials resulting
from the rezoning would remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would neither allow for any increase in the capacity of these
roadways nor propose future development, the proposed project would not have the potential to
emit hazardous emissions or handle hazardous substances near a school. As the proposed project
would not alter the land use designations of the approved project, there would be no changes to the
impacts previously identified. Therefore, the conclusions of the Certified EIR remain valid.
Would the project be located on a site which is included on a list of hazardous materials sites
compiled pursuant to Government Code Section 65962.5 and as a result, would it create a significant
hazard to the public or the environment?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that because development of sites on the
Cortese Hazardous Substances Sites List would be subject to future environmental review, impacts
would be considered less than significant. SEIR No. 346 concluded that because EIR No. 330
contemplated development of the housing opportunity sites, impacts to hazards and hazardous
materials resulting from the rezoning would remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved

would be no changes to the impacts previously identified for buildout of the General Plan under the
approved project. Therefore, the conclusions of the Certified EIR remain valid.
Would the project be located on a site containing aboveground or underground pipelines which
transport hazardous substances or waste other than those serving the site?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that the potential increase in levels of
residential development in The Platinum Triangle, or in any areas located near any pipelines would
potentially be at risk due to rupture or leakage of materials within the pipeline. However, various
goals and policies were incorporated in the adopted General Plan that would ensure impacts would
be less than significant. SEIR No. 346 concluded that because EIR No. 330 contemplated
development of the housing opportunity sites, impacts to hazards and hazardous materials resulting
from the rezoning would remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project does not propose any physical development that impacts pipelines,
there would be no changes to the impacts previously identified. Therefore, the conclusions of the
Certified EIR remain valid.
Would the project be located on a site which is a current or former hazardous waste disposal site or
solid waste disposal site?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 identified no current and
two former solid waste disposal sites in the City of Anaheim, and no liquid or hazardous wastes are
known to have been deposited at these locations. With adherence to the City’s Safety Element Goal
4.1, Policies 1 through 8; and the implementation of Mitigation Measure 5.6-3, provided in EIR No.
330, which would require a Phase I Environmental Assessment to be submitted to the City for
developments at either of these former solid waste disposal sites, impacts to hazards and hazardous
materials would be reduced to less than significant. SEIR No. 346 concluded that because EIR No.
330 contemplated development of the housing opportunity sites, impacts to hazards and hazardous
materials resulting from the rezoning would remain less than significant with mitigation
incorporated.

Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

Certified EIR remain valid.
For a project located within an airport land use plan or, where such a plan has not been adopted,
would the project be located within two miles of a public airport or public use airport, or would the
project result in a safety hazard for people residing or working in the project area? And for a project
within the vicinity of a private airstrip, would the project result in a safety hazard for people residing
or working in the project area?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that accidents
may occur due to the high volume of operational trips being conducted at both airports in the City.
However, the Airport Land Use Commission (ALUC) requires that cities and County general plans and
zoning ordinances limit types of construction and building heights in navigable air space, as well as
regulate the establishment of sensitive uses within close proximity to airports. The ALUC also
established an Airport Environs Land Use Plan that addresses heliport operations, and while there
are no private airstrips within the City, there are several heliports. The approved project included
the redesignation of land uses surrounding heliports and included plans and policies to address land
use risks associated with helicopter operations. With adherence to the City’s Safety Element Goal
4.1, Policies 1 through 8; and the implementation of Mitigation Measures 5.6-4 through 5.6-6,
provided in EIR No. 330, impacts to hazards and hazardous materials would be reduced to less than
significant. SEIR No. 346 concluded that because EIR No. 330 contemplated development of the
housing opportunity sites, impacts to hazards and hazardous materials resulting from the rezoning
would remain less than significant.

Would the project expose people or structures to a significant risk of loss, injury or death involving
wildland fires, including where wildlands areas adjacent to urbanized areas or where residences are
intermixed with wildlands?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that wildland fires would pose a significant
threat to the people and structures as the Hill and Canyon Area is susceptible as a result of its larger
proportion of vegetation and open space. In wildland areas, proper precautions, such as the use of
fire resistant building materials, would protect developed lands from fires and, therefore, reduce
the potential loss of life and property. The approved project includes goals and policies that address
the threat of wildland fires within the City, and impacts would be less than significant. SEIR No. 346
concluded that because EIR No. 330 contemplated development of the housing opportunity sites,
impacts related to wildfires resulting from the rezoning would remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

there would be no changes to the impacts previously identified. Therefore, the conclusions of the
Certified EIR remain valid.
3.6.3 Cumulative Hazards and Hazardous Materials Impacts
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that Development of Emergency Preparedness
Programs, as well as implementation of the goals and policies included in the approved project
would provide adequate safety protection from hazards and hazardous materials. As such, the
approved project’s contribution to cumulative impacts related to hazards and hazardous materials is
less than considerable and less than cumulatively significant. SEIR No. 346 concluded that because
EIR No. 330 contemplated development of the housing opportunity sites, impacts to hazards and
hazardous materials resulting from the rezoning would remain less than significant.
Proposed Project
The proposed project is a policy-level document that would not result in changes to the existing land
uses or development assumptions included under the approved project. Therefore, the proposed
project would not result in cumulatively considerable impacts related to hazards and hazardous
materials and would not alter the conclusions of the Certified EIR related to cumulative impacts. The
conclusions of the Certified EIR remain valid.

3.6.4 Findings Related to Hazards and Hazardous Materials
3.6.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to hazards and hazardous materials, and there would not
be a substantial increase in the severity of impacts described in the Certified EIR.
3.6.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
hazards and hazardous materials that would require major changes to the Certified EIR.
3.6.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time the Certified EIR was approved, indicating that a new
significant effect not reported in that document may occur. Based on the information and analyses
above, there is no substantial new information indicating that there would be a new significant
impact related to hazards and hazardous materials requiring major revisions to the Certified EIR.
3.6.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to hazards and hazardous materials
identified and considered in the Certified EIR.
3.6.5 Mitigation Measures
The mitigation measures from the Certified EIR pertaining to hazards and hazardous materials are
not applicable to the proposed project, as they each include requirements for future development
projects. As the proposed project does not include or propose any physical development, these
mitigation measures do not apply.

3.7 HYDROLOGY AND WATER QUALITY
3.7.1 Existing Environmental Setting
The City lies within Region 8 (Santa Ana) of the California Regional Water Quality Control Board
(RWQCB) jurisdiction. The Santa Ana River is the main surface watercourse within the City and
provides roughly 70 percent of the total groundwater recharge for the Santa Ana River basin. Water
flow is regulated by the Prado Dam, Seven Oaks Dam, and other flood-control facilities. The river’s
unlined channel bottom consists of permeable sandy material and is directly connected to previous
alluvial materials that allow for the transfer of water into the underlying aquifers.
3.7.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project violate any water quality standards or waste discharge requirements?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded implementation of the approved project would
potentially impact the quantity of runoff and other pollutant loadings to receiving waters. However,
policies included in the adopted General Plan would ensure compliance with federal standards, and
impacts were considered to be less than significant. SEIR No. 346 concluded that because EIR No.
330 contemplated development of the housing opportunity sites, the rezoning would also require
compliance with General Plan policies and for future projects, and impacts would remain less than
significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. Design of the Class I Bike Paths would include appropriate best management practices
(BMPs) and would not negatively affect water quality. As the proposed project would not alter the
land use designations or alter development assumptions of the approved project, there would be no
changes to the impacts previously identified. Therefore, the conclusions of the Certified EIR remain
valid.
Would the project substantially deplete groundwater supplies or interfere substantially with
groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the
local groundwater table level (e.g., the production rate or pre-existing nearby wells would drop to a
level which would not support existing land uses or planned uses for which permits have been
granted)?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded implementation of the approved project would
not increase the demand on groundwater supplies and the adopted General Plan contains policies
directing the City to reduce pollution, enforce water quality management regulations, and conserve

water. Therefore, impacts were considered less than significant. SEIR No. 346 concluded that
because EIR No. 330 contemplated development of the housing opportunity sites, the rezoning
would also require compliance with General Plan policies and for future projects and impacts would
remain less than significant.
Proposed Project
The proposed project does not propose any physical development nor does it alter the anticipated
development analyzed under the approved project. The proposed project involves an update to the
City’s Circulation Element for the reclassification of roadways in order to resolve inconsistencies
with existing conditions within the City, amend the Bicycle Master Plan to include two new Class I
Bike Paths, and provide consistency with the MPAH, as amended. The proposed project is a policy-
level document that would not result in changes to the existing land uses or development
assumptions included under the approved project. As the proposed project does not propose future
development, there would be no impacts to groundwater or groundwater supplies. As the proposed
project would not alter the land use designations or development assumptions of the approved
project, there would be no changes to the impacts previously identified. Therefore, the conclusions
of the Certified EIR remain valid.
Would the project substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, or substantially increase the rate or amount
of surface runoff in a manner which would result in flooding on-site or off-site?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that the
increased development throughout the Planning Area may increase impervious surfaces, thereby
increasing runoff and resulting in nuisance flooding in areas without adequate drainage facilities.
The approved project would allow existing commercial and industrial areas to redevelop with mixed-
use projects that may include a greater amount of landscaping, resulting in a greater amount of
acreage available for groundwater recharge and decreased runoff volumes. EIR No. 330 also
concluded that a number of drainage facilities within the City were deficient; however, these were
reduced to a less than significant level with General Plan goals and policies and Mitigation Measures
5.7-1 and 5.7-2, provided in EIR No. 330. SEIR No. 346 concluded that because EIR No. 330
contemplated development of the housing opportunity sites and the rezoning would also require
compliance with General Plan policies and mitigation measures for future projects, impacts would
remain less than significant with mitigation.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. Design of the Class I Bike Paths would include appropriate drainage and would not
negatively affect drainage patterns. As the proposed project would not alter the land use

designations or development assumptions of the approved project, there would be no changes to
the impacts previously identified. Therefore, the conclusions of the Certified EIR remain valid.
Would the project create or contribute runoff water which would exceed the capacity of existing or
planned storm water drainage systems or provide substantial additional sources of polluted runoff?
Or would the project otherwise substantially degrade water quality?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that residential uses involving landscaping may
result in a greater amount of acreage available for groundwater recharge and decreases in runoff
volumes. Drainage deficiencies within the City would be addressed by applicable General Plan goals
and policies. The approved project would protect water quality by requiring residents and
businesses to engage in water quality management practices and pollution control measures. The
adopted General Plan’s goals and policies also direct the City to monitor water quality and provide
water service that meets or exceeds health standards, and impacts were considered less than
significant. SEIR No. 346 concluded that because EIR No. 330 contemplated development of the
housing opportunity sites, the rezoning would also require compliance with General Plan policies
and for future projects, and impacts would remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project does not propose future development and the Class I Bike Paths
would be designed consistent with City drainage standards, the proposed project would not
contribute additional runoff or degrade water quality. As the proposed project would not alter the
development assumptions of the approved project, there would be no changes to the impacts
previously identified. Therefore, the conclusions of the Certified EIR remain valid.
Would the project place housing within a 100-year flood hazard as mapped on a federal flood hazard
boundary or flood insurance rate map or other flood hazard delineation map or place within a 100-
year flood hazard area structures which would impede or redirect flood flows? Or would the project
expose people or structures to a significant risk of loss, injury, or death involving flooding, including
flooding as a result of the failure of a levee or dam? Or would the project be subject to inundation by
seiche, tsunami, or mudflow?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that buildout of the approved project could
expose more people and habitable structures to potential flooding through development of lands
within flood zones and areas subject to dam failure. The policies contained in the adopted General
Plan seek to protect structures and residents within flood zones by requiring all development
proposals to undergo an evaluation process to determine flood risks and ensure compliance with

local, State, and federal regulations. There is a low-to-moderate potential for flooding due to seiche
hazards affecting properties adjacent to the Walnut Canyon Reservoir. The City of Anaheim is not
located close enough to the coast to be subject to possible impacts from a tsunami. Potential
impacts from mudflow would be addressed by the goals and policies of the adopted General Plan.
Therefore, impacts were considered to be less than significant. SEIR No. 346 concluded that because
EIR No. 330 contemplated development of the housing opportunity sites, the rezoning would also
require compliance with General Plan policies and for future projects, and impacts would remain
less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project does not propose future development in a floodplain, the proposed
project would not expose people or structures to potential hazards from flooding or inundation. As
the proposed project would not alter the land use designations or development assumptions of the
approved project, there would be no changes to the impacts previously identified. Therefore, the
conclusions of the Certified EIR remain valid.
3.7.3 Cumulative Hydrology and Water Quality Impacts
Approved Project
Less Than Significant Impact. Cumulative impacts for hydrology and water quality are dependent on
the specific development proposed and the flood control/drainage improvements specific to the
development. Mitigating the increases in impervious surfaces is best addressed on a site-specific
basis and the adopted General Plan contains goals and policies to address hydrology and water
quality impacts. As such, the approved project’s contribution to cumulative impacts related to water
quality and hydrology was considered less than considerable and less than cumulatively significant.
SEIR No. 346 concluded that because EIR No. 330 contemplated development of the housing
opportunity sites, the rezoning would also require compliance with General Plan policies and for
future projects, and impacts would remain less than cumulatively considerable.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document that would not result in changes to the
existing land uses or development assumptions included under the approved project. Therefore, the
proposed project would not result in cumulatively considerable impacts related to hydrology and
water quality, and the conclusions of the Certified EIR remain valid.

3.7.4 Findings Related to Hydrology and Water Quality
3.7.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to hydrology and water quality, and there would not be a
substantial increase in the severity of impacts described in the Certified EIR.
3.7.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
hydrology and water quality that would require major changes to the Certified EIR.
3.7.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
This Addendum has analyzed all available relevant information to determine whether there is new
information that was not available at the time the Certified EIR was certified, indicating that a new
significant effect not reported in that document may occur. Based on the information and analyses
above, there is no substantial new information indicating that there would be a new significant
impact related to hydrology and water quality requiring major revisions to the Certified EIR.
3.7.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR
There is no new information, mitigation, or alternatives to the proposed project that would
substantially reduce one or more significant impacts pertaining to hydrology and water quality
identified and considered in the Certified EIR.
3.7.5 Mitigation Measures
The mitigation measures from the Certified EIR pertaining to hydrology and water quality are not
applicable to the proposed project, as they each include requirements for future development
projects. As the proposed project does not include or facilitate any physical development, these
mitigation measures do not apply.

3.8 NOISE
3.8.1 Existing Environmental Setting
No substantial changes to the Planning Area have occurred since the preparation of the Certified
EIR. Noise-sensitive receptors in the City include residences, schools, hospitals, churches, and similar
uses. The major sources of noise are mobile sources of traffic traveling on various roadways and
freeways, as well as freight and commuter rail-traffic. Aircraft also contribute to this noise. The City
is not located within the 65 A-weighted decibel (dBA) Community Noise Equivalent Level (CNEL)
contours for any commercial or private airports, and fixed-wing aircraft typically fly too high to add
measurably to local noise. However, local helicopter air traffic is commonplace throughout the City
and was noted in many instances during the field survey performed in drafting the General Plan
Noise Element. The City also includes stationary noise sources from industrial land uses that are
mostly restricted to appropriate areas. Sources of “stationary” noise also include the regular
fireworks displays at Disneyland and special events at Angel Stadium.
3.8.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project result in exposure of persons to or generation of noise levels in excess of standards
established in the local general plan or noise ordinance, or applicable standards or other agencies;
would the project result in substantial permanent increase in ambient noise levels in the project
vicinity above levels existing without the project; would the project result in a substantial temporary
increase in ambient noise levels in the project vicinity above levels existing without the project?
Approved Project
Significant and Unavoidable Impact. EIR No. 330 concluded that temporary increases in ambient
noise from construction activities anticipated for General Plan buildout would cause substantial
increases at noise-sensitive uses surrounding construction sites compared to typical urban
environments of 50 to 70 dBA. Potential impacts would be reduced to less than significant at the
project level through the enforcement of the Anaheim Municipal Code and policies of the General
Plan Noise Element.
Vehicle-generated noise contours and the siting of sensitive land uses within these contours for the
approved project represented a potentially significant impact and would require a separate noise
study through the development review process to determine project-level impacts and required
mitigation. In addition, the approved project anticipated an increase in railroad operations that
would have a potentially significant noise impact on nearby residents. Implementation of the goals
and policies included in the approved project, existing codes and regulations, and mitigation
measures would reduce all potential short-term and long-term noise impacts to the extent feasible.
However, many roadways within the City are expected to generate noise levels exceeding 65 CNEL,
and the impacts were determined to be significant and unavoidable. SEIR No. 346 concluded that
mitigation of construction noise impacts would be conducted at the project level through both the
enforcement of the Anaheim Municipal Code and the policies of the General Plan Noise Element.
In addition, SEIR No. 346 concluded that the development of residential projects at each of the 221
housing opportunity sites would be designed to meet the City’s noise standards. Prior to issuance of
building permits, the property owner/developer would be required to demonstrate that a project’s
noise levels would be less than 65 dBA CNEL for future proposed outdoor use areas. Therefore,

impacts concerning stationary noise and noise-sensitive receptors would be less than significant.
SEIR No. 346 also concluded that the primary noise source within the Planning Area was unchanged
from EIR No. 330 and would not alter the traffic-generated noise as a result of General Plan
buildout. Operational impacts related to traffic-generated-noise would remain significant and
unavoidable.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project neither allows for any increase in the capacity of these roadways
nor proposes future development beyond what was analyzed under the approved project, the
proposed project would not alter the ADT and vehicle-generated noise anticipated by the approved
project. The proposed project would not result in any increases in ambient noise or expose persons
to noise levels in excess of applicable standards as a result of construction or operation. However, as
the proposed project would not alter the land use designations or development assumptions of the
approved project, the proposed project would also not reduce the significant and unavoidable
impacts identified for the approved project, and the conclusions of the Certified EIR remain valid.
Would the project result in exposure of persons to or generation of excessive groundborne vibration
or groundborne noise levels?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that construction activities are the primary
sources of groundborne vibration within the Planning Area. Short-term exposure to vibration levels
would be considered a potentially significant impact; however, construction activities would comply
with the City’s hourly restrictions and are intermittent and short-term in nature and therefore would
not result in a significant increase in annoyance. Individual development projects would be subject
to site-specific environmental review, which would necessitate identification of site-specific
mitigation in the event that significant impacts are identified. SEIR No. 346 concluded that buildout
of the General Plan could potentially cause vibration impacts during construction of individual
projects on the 221 housing opportunity sites. Excessive groundborne vibration is typically caused by
activities such as blasting or the use of pile drivers during construction, which would be addressed at
the time of specific development applications, and impacts were considered to remain less than
significant.

The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency

in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would not generate groundborne vibration or groundborne noise. As
the proposed project would not alter the development assumptions of the approved project, there
would be no changes to the impacts previously identified, and the conclusions of the Certified EIR
remain valid.
For a project located within an airport land use plan or, where such a plan has not been adopted,
within two miles of a public airport or public use airport, would the project expose people residing or
working in the project area to excessive noise levels; for a project within the vicinity of a private
airstrip would the project expose people residing or working in the project area to excessive noise
levels?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that the ALUC
was established to ensure that no direct conflicts with land uses, noise, or other issues would occur
or would impact the functionality and safety of airport and heliport operations. Land use conflicts
between the designated land uses of the approved project and airport and heliport safety and
operations would be mitigated to a less than significant level with implementation of Mitigation
Measure 5.10-2, provided in EIR No. 330, requiring future development to use the most current
airport environs land use plan as a planning resource for consistency. SEIR No. 346 concluded that
Mitigation Measure 5.10-2 from EIR No. 330 would remain applicable to the future development
anticipated as a result of the rezoning, which was also anticipated under the General Plan buildout,
and therefore the conclusions of EIR No. 330 remain valid.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not facilitate future development near an airport, the
proposed project would not have the potential to expose persons to noise levels related to public
airports, private airstrips, or heliports. As the proposed project would not alter the development
assumptions of the adopted General Plan, there would be no changes to the impacts previously
identified. Therefore, the conclusions of the Certified EIR remain valid.

3.8.3 Cumulative Noise Impacts.
Approved Project
Cumulatively Considerable Impacts. EIR No. 330 concluded that because construction activities
associated with development projects are localized and duration and intensity are limited,
construction- generated noise and vibration levels would not contribute substantially to the
cumulative noise environment at any given location. However, due to the scale of development
activity associated with the approved project, roadways within the City would still be expected to
generate significant noise impacts. Mitigation Measures 5.10-1 and 5.10-2, provided in EIR No. 330,
would reduce operational noise impacts to the extent feasible. SEIR No. 346 concluded that because
EIR No. 330 contemplated development of the housing opportunity sites, the rezoning would also
require compliance with General Plan policies and mitigation measures for future projects; however,
the rezoning would not alter the development assumptions, and impacts would remain significant
and unavoidable.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project is a policy-level document that would not result in changes to the
existing land uses or development assumptions included under the approved project. Therefore,
while the proposed project would not result in cumulatively considerable impacts related to noise;
the proposed project would not alter the conclusions of the Certified EIR related to cumulative
impacts. The conclusions of the Certified EIR remain valid.
3.8.4 Findings Related to Noise
3.8.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to noise, and there would not be a substantial increase in
the severity of impacts described in the Certified EIR.

3.9 PUBLIC SERVICES AND FACILITIES
3.9.1 Existing Environmental Setting
No substantial changes to the Planning Area have occurred since the preparation of the Certified
EIR; however, the current information for public services and utilities within the City is provided
below.
Fire Protection. The Anaheim Fire Department is responsible for fire protection in the City of
Anaheim. The Anaheim Fire Department operates 11 fire stations and employs a total of 278 safety
and full-time personnel.
Police Protection. Law enforcement in the City is provided by the Anaheim Police Department. The
Anaheim Police Department currently employs over 400 sworn officers and upwards of 170 civilian
support staff.
Public Schools. The Anaheim City School District, Anaheim Union High School District, Orange
Unified School District, Centralia School District, Magnolia School District, Savanna School District,
Fullerton School District, Fullerton Joint Union School District, Placentia-Yorba Linda Unified School
District, Garden Grove Unified School District, and Buena Park School District provide educational
services to the City.
Public Libraries. The City of Anaheim Library Services Division maintains a Strategic Plan to guide the
future development of the City’s libraries and there are ten library branches serving the City.
Water. With the exception of several small areas bordering the City limits, the Anaheim Public
Utilities Department provides water service throughout the City. The system includes approximately
744 miles of water mains, 61,500 active water meters, and over 7,800 fire hydrants. The system
facilities also include eight water connections to the Metropolitan Water District of Southern
California, 27 active wells, one 920-million-gallon (MG) reservoir for untreated water, one 15 MG
per day water treatment plant, 12 reservoirs with a total capacity of more than 29 MG for treated
water, seven chlorination facilities, and nine booster pump stations.
Wastewater. Sewage is collected by City collector facilities and conveyed to trunk sewers owned
and maintained by the Orange County Sanitation District. There are small portions of the City that
receive local sewer service from adjacent agencies, including the City of Stanton Water District and
the City of Garden Grove Sanitary District. Two Orange County wastewater treatment plants serve
the Planning Area.
Electric Power. The Anaheim Public Utilities Department’s Electrical Division provides electricity to
Anaheim’s citizens and business industries. The distribution system consists of approximately 1,500
circuit miles of transmission and distribution lines, over 500 miles of which are underground. In
order to facilitate the safe and efficient transfer of electricity to residences and businesses, ten
distribution substations are located throughout the City.
Natural Gas. Southern California Gas Company provides gas service in the City of Anaheim and has
facilities throughout the City. The availability of natural gas service is based upon present conditions

of gas supply and regulatory policies. As a public utility, Southern California Gas Company is under
the jurisdiction of the Public Utilities Commission and federal regulatory agencies.
Telecommunication Facilities. Telephone, television, and internet services are offered by a variety
of providers in the City of Anaheim, including AT&T, Cox Communications, Earthlink, and Starry
Internet. Non-satellite providers include Frontier, DirectTV, Spectrum Cable, and DishTV. Satellite
internet providers include ViaSat. These services are privately operated and offered to each location
in the City for a fee defined by the provider.
Landfills. Orange County owns and operates three active landfills. These are Olinda Alpha Landfill
near Brea, the Frank R. Bowerman Landfill near Irvine, and the Prima Deshecha Landfill in San Juan
Capistrano. In order to ensure that the maximum permitted daily tonnage at a particular landfill is
not exceeded, refuse trucks may have to transport material to one or the other. In October 2020,
the anticipated landfill closure date for the Olinda Landfill was extended to 2036 due to increased
recycling and waste diversion.4
3.9.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project result in substantial adverse physical impacts associated with the provision of new
or physically altered government facilities, need for new or physically altered government facilities,
the construction of which could cause significant environmental impacts, in order to maintain
acceptable service ratios, response times, or other performance objectives?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that the
approved project would increase the overall demand on fire and police protection services and new
facilities would need to be developed to provide adequate response times to serve future growth.
However, additional personnel and materials costs may be offset through the increased revenue and
fees generated by future development. In addition, Mitigation Measure 5.11-1, provided in EIR No.
330, was included to require future projects to be reviewed by the City of Anaheim on an individual
basis and to comply with requirements in effect at the time building permits are issued or with
appropriate mitigation measures.
EIR No. 330 also concluded that the approved project would allow for the construction of additional
residential units resulting in an increased demand on schools and library services. The Library
Facilities’ Master Plan and would meet the need for library building space. While future growth
would result in increased need for school facilities, the City was precluded per SB 50 to consider this
a significant impact for the purposes for CEQA. The General Plan goals and policies, in addition to
development fees, would further reduce potential impacts, and Mitigation Measure 5.13-1,
provided in EIR No. 330, was included to identify new school sites and expansions.

EIR No. 330 also concluded that the approved project would result in development that may require
expansion of infrastructure for energy supply and telecommunications facilities and services in the
Planning Area. However, the provision for these services was not anticipated to require substantial
alterations. With implementation of the goals and policies included in the adopted General Plan, no
significant impacts related to the provision of electricity, natural gas, telephone, or cable services
were anticipated.
SEIR No. 346 concluded that because EIR No. 330 contemplated development of the housing
opportunity sites, the rezoning would also require compliance with the mitigation measures
included in EIR No. 330 and compliance with General Plan policies and for future projects, and
impacts would remain less than significant with mitigation incorporated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended.. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not alter the development assumptions of the approved
project, there would be no impacts related to construction of new facilities or impacts to service
ratios for public services or facilities. The proposed project would not change the impacts previously
identified for the approved project, and the conclusions of the Certified EIR remain valid.
Would the project require or result in the construction of new water and wastewater treatment
facilities, or expansion of existing facilities, the construction of which could cause significant
environmental effect, have insufficient water supplies being available to serve the project from
existing entitlements and resources, or have new or expanded entitlements needed? Or would the
project result in a determination by the wastewater treatment provider that serves or may serve the
project that it has inadequate capacity to serve the project’s projected demand in addition to the
provider’s existing commitments?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. EIR No. 330 concluded that the
approved project would increase residential units and office square footage within the City,
resulting in localized increases in water demands and sewer services. As the size, location, and form
of future growth is unknown, impacts to water and wastewater services could occur, but would be
mitigated to less than significant at the project level through implementation of Mitigation
Measures 5.13-3 through 5.13-6, provided in EIR No. 330, and compliance with goals and policies
outlined in the adopted General Plan. SEIR No. 346 concluded that because EIR No. 330
contemplated development of the housing opportunity sites, the rezoning would also require
compliance with the mitigation measures included in EIR No. 330 and compliance with General Plan
policies and for future projects, and impacts would remain less than significant with mitigation
incorporated.

assumptions of the approved project, there would be no impacts related to construction of new
facilities or to service ratios for water or wastewater infrastructure. The proposed project would not
change the impacts previously identified for the approved project, and the conclusions of the
Certified EIR remain valid.
Would the project not be served by a landfill with sufficient permitted capacity to accommodate the
project’s solid waste disposal needs? Or would the project not comply with federal, state and local
statutes and regulations related to solid waste?
Less Than Significant Impact. EIR No. 330 concluded that the projected solid waste generation
would be slightly reduced under the approved project and would be consistent with County
Integrated Waste Management Department (IWMD) projections and the permitted capacities at
the Olinda Landfill, the Frank R. Bowerman Landfill, and the Prima Deshecha Landfill, which would
serve the City. Therefore, no significant impacts were anticipated. Furthermore, EIR No. 330
concluded that the approved project would not alter the City’s compliance with federal, State, and
local statutes related to solid waste. SEIR No. 346 concluded that because EIR No. 330 contemplated
development of the housing opportunity sites, the rezoning would also require compliance with
applicable federal, State, and local statutes for future projects, and impacts would remain less than
significant.

EIR No. 330 concluded that service agencies incorporate growth anticipated in the adopted General
Plan into their long-range planning programs and that standard measures such as the payment of
fees and incorporation of needed facilities would be addressed in future projects as determined

appropriate in individual EIR analyses. Therefore, no significant impacts would occur associated with
the proposed project related to public services and utilities. As such, the approved project’s
contribution to cumulative impacts related to public service and utilities was less than considerable
and less than cumulatively significant. SEIR No. 346 concluded that because EIR No. 330

3.10 TRANSPORTATION AND TRAFFIC
3.10.1 Existing Environmental Setting
No substantial changes to the Planning Area have occurred since the preparation of the Certified
EIR, and the City’s circulation system as provided in the adopted Circulation Element is described
below.
Existing Classification System. The City’s circulation network provides access to adjacent land uses
and facilitates the movement of persons and goods through the City. The adopted General Plan uses
a functional classification system consistent with classification systems used throughout Orange
County. It includes the following arterial street classifications: Major; Primary; Secondary; Collector
Streets; Scenic Expressways, Complete Streets Collectors, and Smartstreets, and various hillside
classifications. The existing Circulation Element Planned Roadway Network (as identified in
Figure C-1) currently shows Yorba Linda Boulevard from the City limits to SR-91 as a Primary Arterial,
even though under existing conditions and at the time of the approved project, this roadway was
generally developed as a six-lane roadway 5 that connects to a freeway, consistent with the
classification of a Major Arterial. The existing Circulation Element currently does not depict Savi
Ranch Parkway, Crystal Drive, Pullman Street, or Old Canal Road. However, the current
configurations of these roadways as four-lane and two-lane facilities have not changed since
adoption of the existing Circulation Element.
Existing Transit Service. The OCTA operates the local public transit routes that extend into the City.
Existing Bicycle and Pedestrian Facilities. The City currently has four classifications of bikeways:
Class I Bikeways, which provide a completely separated right-of-way designated for the exclusive
use of bicycles and pedestrians with crossflows by motorists minimized; Class II Bikeways, which
provide a restricted right-of-way designated for the exclusive or semi-exclusive use of bicycles with
through travel by motor vehicles or pedestrians prohibited, but with vehicle parking and crossflows
by pedestrians and motorists permitted; Class III bikeways, which provide a right-of-way on-street or
off-street, designated by signs or permanent markings and shared with pedestrians and motorists;
and Class IV Bikeways referred to as Cycle Tracks, which provide a bikeway adjacent to a roadway
separated by a barrier or by on-street parking. The City’s circulation has been designed to include
pedestrian circulation through the provision of sidewalks within street rights-of-way.
Existing Volumes and Levels of Service (LOS) Analysis. The City uses a level of service standard to
describe both existing and future traffic conditions. LOS analysis is a qualitative ranking that
characterizes traffic congestion on a scale of A through F, with LOS A being a free-flow/best
condition and LOS F representing failure/extreme congestion. The Circulation Element establishes
that the LOS standard should be LOS D or better for MPAH intersections in the City. The Congestion
Management Plan (CMP) establishes that the LOS standard should be LOS E or better for CMP
roadways and intersections.
5 A small portion includes a seventh lane in the southbound direction which becomes an SR-91 merge lane.

3.10.2 Comparison of Impacts for the Approved Project and the Proposed Project
Would the project cause an increase in traffic which is substantial in relation to the existing traffic
load and capacity of the street system? Or would the project exceed, either individually, or
cumulatively, a level of service standard established by the congestion management agency for
designated roads or highways?
Approved Project
Significant and Unavoidable Impact. EIR No. 330 concluded that the future conditions scenario for
the approved project identified intersections that are anticipated to operate at an unacceptable
level of service in 2025 as well as intersections projected to operate at LOS E or F requiring
additional enhancements beyond those planned in the Circulation Element, including two CMP
intersections determined to operate at a deficient LOS. The improvements necessary to maintain
adequate levels of service may impact adjacent land uses but would be considered significant if the
City chooses not to implement the required improvements.
SEIR No. 346 concluded that the number of intersections performing at LOS E or F during the AM
peak hour worsened from six to seven; however, the number of intersections that are performing at
LOS E or F during the PM peak hour improved from 18 to 13 using an updated traffic model. SEIR No.
346 modified mitigation measures from EIR No. 330 to maintain acceptable levels of service as
identified in the updated traffic modeling data. SEIR No. 346 also provided additional mitigation for
intersection improvements for the 20 intersections and to construct the roadways identified in
Circulation Element Figure C-1 to accommodate future growth established by the Land Use Element.
Similar to EIR No. 330, SEIR No. 346 concluded there are numerous physical constraints associated
with the proposed improvements, including private properties, extensive circulation landscaping,
and mature trees, and a variety of hotels and other businesses that would likely be impacted.
Consequently, impacts were considered to remain significant and unavoidable.
Proposed Project
Subsequent to certification of SEIR No. 346 in 2013, the California Office of Administrative Law
cleared revised State CEQA Guidelines for use. Among the changes to the guidelines was the
removal of vehicle delay and LOS from consideration under CEQA. With the adopted guidelines,
transportation impacts are now to be evaluated based on a project’s effect on vehicle miles traveled
(VMT). The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project neither proposes any physical development that
would result in additional traffic nor alters the anticipated development analyzed under the
approved project that would generate additional VMT. The proposed project is a policy-level
document that would update roadway classifications consistent with existing conditions and would
add new Class I Bike Paths along portions of Yorba Linda Boulevard and La Palma Avenue, but would
not alter the Circulation Element or the Bicycle Master Plan goals or policies related to establishing
measures of effectiveness for intersections. As the proposed project would not increase roadway
capacity or additional trips generated, there would be no additional impacts to the intersection
capacity. Consistent with the revised State CEQA Guidelines Section 15064.3(b), the project would
neither allow for any increase in the capacity of the roadway, induce future growth that would lead

to an increase in VMT, nor change the measures of effectiveness at any intersections. The addition
of Class I Bike Paths along portions of Yorba Linda Boulevard and La Palma Avenue including a
connection to the Santa Ana River Trail would be developed as a separated bikeway and would not
impact existing adjacent traffic load, capacity, or level of service. The proposed bike paths would
continue to promote bicyclist safety and development of multimodal roadways in the City.
Therefore, the proposed project would not conflict with an applicable plan, ordinance, or policy
establishing measures of effectiveness for intersections or be inconsistent with State CEQA
Guidelines Section 15064.3(b). The proposed project would reflect the current geometric
configuration of the roads, the ADT of the roadway segments, and LOS at the relevant intersections,
and would not change the impacts previously identified for the approved project. The General Plan
would be updated to reflect the roadway and bikeway classifications, but the proposed project does
not propose any of the future improvements identified in the Certified EIR for mitigation. Therefore,
the conclusions of the Certified EIR remain valid.
Would the project result in a change in air traffic patterns, including either an increase in traffic
levels or change in location that resulting in substantial safety risk? Or would the project
substantially increase hazards due to a design feature or incompatible uses?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that although the approved project would
result in changes to the land use and zoning standards in portions of the City, the changes would not
impact air traffic patterns. Changes to the circulation network resulting from the approved project
would not increase hazards due to a design feature due to City roadway design standards, which
would preclude the construction of unsafe design features. Therefore, no impacts were anticipated.
SEIR No. 346 concluded that the rezoning was anticipated in the adopted General Plan buildout
scenario and would not increase hazards due to a design feature. The City’s adopted roadway design
standards would also apply to future development and would preclude the construction of any
unsafe design features. Therefore, no impacts were anticipated.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City and provide consistency with the MPAH, as amended. Additionally, the proposed project would
update the Bicycle Master Plan to include new Class I Bike Paths. The proposed project is a policy-
level document that would not result in changes to the existing land uses or development
assumptions included under the approved project. The proposed project would not have the
potential to result in changes to air traffic patterns or other safety hazards from hazardous design
features. Therefore, no impacts would occur, and the conclusions of the Certified EIR remain valid.
Would the project result in inadequate emergency access or parking capacity?
Approved Project
Less Than Significant Impact. EIR No. 330 concluded that the Circulation Element included in the
approved project was designed to provide and maintain a comprehensive circulation system within

the City at buildout. Adequate levels of service would be maintained with the exception of three
intersections, and no significant impacts to emergency access were associated with the approved
project. SEIR No. 346 also concluded that adequate levels of service would be maintained with the
exception of seven intersections after mitigation and that rezoning would not impact emergency
access. As a result, no significant impacts to emergency access would occur, and impacts would
remain less than significant.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. As the proposed project would not alter the configurations of the roadways, the proposed
project would not have the potential to result in changes to emergency access or parking. Therefore,
the conclusions of the Certified EIR remain valid.
Would the project comply with adopted policies, plans and programs for alternative transportation?
Approved Project
No Impact. EIR No. 330 did not include this threshold; however, SEIR No. 346 concluded that similar
to the analysis provided in EIR No. 330, the rezoning would require compliance with the adopted
General Plan which includes goals and policies to promote alternative modes of transportation.
Therefore, SEIR No. 346 concluded that the approved project is consistent with the Orange County
Sub-regional Sustainable Communities Strategy, which includes measures to reduce dependence on
the automobile, and no impacts would occur.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project would update the Circulation Element to reflect existing conditions.
Addition of Class I Bike Paths will provide additional alternatives to the use of motor vehicles within
this part of the City of Anaheim. The proposed project would not alter the goals and policies
included in the Circulation Element or Bicycle Master Plan related to alternative transportation.
Therefore, the conclusions of the Certified EIR remain valid.

3.10.3 Cumulative Transportation and Traffic Impacts
Approved Project
Cumulatively Considerable Impacts. EIR No. 330 concluded that cumulative travel patterns within
the Planning Area would be directly influenced by changes to the surrounding regional
transportation system. Significant impacts on transportation are associated with several regional
serving streets, such as Harbor Boulevard and Ball Road, which is a significantly impacted
intersection, and impacts were considered to be cumulatively significant. SEIR No. 346 included
additional mitigation for operation of intersections within the Planning Area; however, it was noted
that there were numerous physical constraints associated with the improvements that would limit
the ability to ensure that the improvements necessary could be implemented. Consequently,
impacts were determined to remain significant and unavoidable.
Proposed Project
The proposed project does not alter the anticipated development analyzed under the approved
project. The proposed project involves an update to the City’s Circulation Element for the
reclassification of roadways in order to resolve inconsistencies with existing conditions within the
City, amend the Bicycle Master Plan to include two new Class I Bike Paths, and provide consistency
with the MPAH, as amended. The proposed project is a policy-level document that would not result
in changes to the existing land uses or development assumptions included under the approved
project. The proposed project is a policy-level document that would update the General Plan
Circulation Element consistent with existing conditions and add Class I bike paths. The proposed
project would not update the roadway and bicycle path designations in a manner that would
accommodate future growth or conflict with existing traffic load, capacity, or level of service.
3.10.4 Findings Related to Transportation and Traffic
3.10.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR
Based on the foregoing analysis and information, there is no evidence that the proposed project
requires a major change to the Certified EIR. The proposed project would not result in new
significant environmental impacts related to transportation and traffic, and there would not be a
substantial increase in the severity of impacts described in the Certified EIR.
3.10.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
transportation and traffic that would require major changes to the Certified EIR.
3.10.4.3 No New Information Showing Greater Significant Effects than the Certified EIR
No major changes to the Planning Area have taken place since preparation of the Certified EIR that
would require revisions to the analysis in the Certified EIR. There is no information in the record or
otherwise available that indicates that there are substantial changes in circumstances pertaining to
transportation and traffic that would require major changes to the Certified EIR.
