Linda Vi Tank and Pump Station Project— Draft Initial Study /Mitigated Negative Declaration
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration
1.0 Introduction
1.1 PURPOSE OF THE INITIAL STUDY
This Initial Study /Mitigated Negative Declaration has been prepared in accordance with the California
Environmental Quality Act (CEQA, Public Resources Code, Section 21000 et seq.) and the City of
Anaheim CEQA procedures as amended, to evaluate the potential environmental impacts associated
with the implementation of the proposed project. The City of Anaheim is the Lead Agency for the
project under CEQA and, as such, has primary responsibility for approving the project.
The Initial Study evaluates the potential environmental impacts associated with the project for each
environmental category listed in CEQA's Environmental Checklist Form. The purpose of this
document is to evaluate the environmental impacts from the replacement and removal of an existing
4.0 million gallon (MG) partially buried reservoir with a new, partially buried 4.0 MG tank. Also on the
site is a dual booster pump station with pumps serving two separate pressure zones delivering water to
both west Anaheim, flatland area, (400 Zone) and east Anaheim, the Hill and Canyon area (555 Zone).
The existing pump station will be relocated so that they are in closer proximity to the new tank. The
reservoir, pump station, and associated facilities are located on a 5.3 acre site composed of 2 adjoining
parcels (see Figure 2).
1.2 FINDINGS OF THE INITIAL STUDY
The Initial Study consists of the Environmental Checklist and Technical Appendices and is the
environmental assessment used to determine whether the proposed project will result in any significant
environmental impacts that would require preparation of an Environmental Impact Report (EIR) or
result in any negative impacts upon the environment that would require mitigation measures. The
Initial Study for the project indicates that implementation of the project will not result in any significant
effects on the environment; therefore, a Mitigated Negative Declaration has been prepared for the
project.
1.3 CONTACT PERSONS
The Lead Agency for the Initial Study is the City of Anaheim. Any questions about its preparation

Linda Vista Tank and Pump Station Pr — Draft Initial Study /Mitigated Negative Declaration 2 -1
2.0 Project Summary
2.1 PRO 'ECT LOCATION
The proposed project is located at the Linda Vista Complex located at 1411 N. Tustin Avenue in the
City of Anaheim between Orangethorpe Avenue and Miraloma Avenue (see Figures 1 through 3). The
site is located in the Northeast Specific Plan Redevelopment Area, otherwise known as the Hill and
Canyon area. Light industrial uses are located south and east of the site. The OCWD's recharge basin
and seasonal recreational fishing site, Anaheim Lake, is located immediately west and north of the site.
The nearest residential neighborhood is located approximately one - quarter of a mile north of the
project site and north of the BNSF Northern Santa Fe railroad in the City of Placentia.
The Linda Vista Reservoir project site is 5.3 acres and is composed of 2 parcels; referred to as Site 1
and Site 2 for the purposes of this document (refer to Figures 1 and 2). Site 1 is characterized by a
relatively flat level surface consisting of a sand /gravel groundcover and contains a pressure regulating
station and four moderately- sized, single story buildings associated with the reservoir and pump station.
A row of ornamental trees is located along a portion of the western border of the site, adjacent to
OCWD's facility and several other ornamental trees and shrubs are located sporadically throughout the
site. Site 2 is relatively flat and is primarily occupied by the existing reservoir, a dual pump station,
weather station and one small electrical/ control building. The reservoir's roof structure is raised above
the ground by a couple feet. A paved access road runs around the entire reservoir.
2.2 PROJECT DESCRIPTION
The Linda Vista 4.0 MG storage reservoir was constructed in the 1935 and has reached its design life.
The reservoir lining requires extensive rehabilitation and the structure does not meet seismic code.
Additionally, pumping capacities are not adequately sized to meet future demands. The proposed
project will replace the existing 4.0 MG reservoir with a new 4.0 MG partially -buried (6 feet below and
32.5 ft above ground) pre - stressed concrete tank (148 -ft inside diameter) The new tank will be located
in the southern area of Site 1 (see Figure 4). The existing reservoir will be demolished and completely
removed. The existing pump station will be relocated north of the new tank location (see Figure 4); the
new expanded pump station will support the relocated existing pumps and motors as well as additional
pumps for future capacity increases. In addition to the reservoir and pump station replacement, new
water pipelines will be installed as well as block wall, fencing and other general civil, and electrical site
work to support the new facilities. New landscaping and irrigation will be added to the site with the
removal of some existing ornamental landscaping.
2.3 PROJECT BACKGROUND
The Linda Vista Reservoir and Pump Station is one of the City's 13 water supply reservoirs and is a critical
component in the City's potable water supply system as it serves both the "flatland" and Hill and Canyon
areas of the City. The existing 10 -ft. deep concrete lined, trapezoidal 4.0 MG reservoir is located on Site 2
and was constructed as an open reservoir in 1935. The open reservoir was enclosed with a roof cover (250'
x 250') in 1962 with approximately 2 -4 feet height visibility aboveground. The 555 pressure zone pumps
were constructed in 1962 and the 400 pressure zone pumps were installed in 1992. The reservoir is supplied
with water from four of the City's production wells that are located on the adjacent OCWD recharge basin
property. Other facilities located in buildings on the site that support the reservoir and the pump station
Lin Vist T and P Stat Pr oject— Draft Initial Study /Mitigated Negative Declaration 2 -2
include the emergency diesel generator, instrumentation and control, a sodium hypochlorite disinfection
system, and the ammonia system (for potential future use). The sodium hypochlorite is used to disinfect
water from the wells to the reservoir and also serves as storage and supply for other City -owned water
treatment facilities. Other onsite facilities include the remote SCADA operations center, a pressure
reducing station, PR -34, weather station and storage areas. An existing 42 -inch steel pipe is located in a 10-
foot wide utility easement that runs from the wells then parallel along the west property line. This
transmission line will connect to the proposed tank's reservoir fill piping.

DETERMINATION: (To be completed by the City) On the basis of this initial evaluation:
❑ I find that the proposed project COULD NOT have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
Q I find that although the proposed project could have a significant effect on the environment, there
will not be a significant effect in this case because revisions in the project have been made by or
agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be
prepared.
❑ I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
❑ I find that the proposed project MAY have a "potentially significant impact" or "potentially
significant unless mitigated" impact on the environment, but at least one effect 1) has been
adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been
addressed by mitigation measures based on the earlier analysis as described on attached sheets. An
ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that
remain to be addressed.
❑ I find that although the proposed project could have a significant effect on the environment,
because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or
NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or
mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or
mitigation measures that are imposed upon the proposed project, nothing further is required.

EVALUATION OF ENVIRONMENTAL IMPACTS:
1) All answers must take account of the whole action involved, including offsite as well as onsite,
cumulative as well as project - level, indirect as well as direct, and construction as well as operational
impacts.
2) A list of "Supporting Information Sources" must be attached and other sources used or individuals
contacted should be cited in the Narrative Summary for each section.
3) Response Column Heading Definitions:
a) Potentially Significant Impact is appropriate if there is substantial evidence that an effect
may be significant. If there are one or more "Potentially Significant Impact" entries when the
determination is made, an EIR is required.
b) Less Than Significant With Mitigation applies where the incorporation of mitigation
measures has reduced an effect from "Potentially Significant Impact" to a "Less Than
Significant Impact ". The mitigation measures must be described, along with a brief
explanation of how they reduce the effect to a less than significant level.
c) Less Than Significant Impact applies where the project creates no significant impacts, only
Less Than Significant impacts.
d) No Impact applies where a project does not create an impact in that category. A "No Impact"
answer is adequately supported if the referenced information sources show that the impact
simply does not apply to projects like the one proposed (e.g., the project falls outside of a fault
rupture zone). A "No Impact" answer should be explained where it is based on project- specific
factors as well as general standards (e.g., the project will not expose sensitive receptors to
pollutants, based on a project- specific screening analysis).
4) Earlier analyses may be used where, pursuant to a tiering, program EIR, Master EIR, or other
CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration
(Section 15062C(3)(D)). In this case, a brief discussion should identify the following:
a) Earlier Analysis Used. Identify and state where they are available for review.
b) Impacts Adequately Addressed. Identify which effects from the checklist were within the scope
of and adequately analyzed in an earlier document pursuant to applicable legal standards, and
state whether such effects were addressed by mitigation measures based on the earlier analysis.
c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures
Incorporated ", describe the mitigation measures which were incorporated or refined from the
earlier document and the extent to which they address site - specific conditions for the project.
5) Incorporate into the checklist any references to information sources for potential impacts (e.g.,
the General Plan, zoning ordinance). Reference to a previously prepared or outside document
should include a reference to the page or pages where the statement is substantiated.
6) The explanation of each issue should identify:
a) the significance criteria or threshold, if any, used to evaluate each question; and the
b) mitigation measure identified, if any, to reduce the impact to less than significant.

Discussion
The project site consists of 2 contiguous parcels (referred to as Site 1 and Site 2 for the purposes of this
document — see Figure No. 2) totaling 5.3 acres located within the Northeast Area Specific Plan (SP94 -1),
Development Area 1 zone. According to the City of Anaheim Municipal Code,
"This development area (Northeast Area Specific Plan 94 -1) is intended to provide for and encourage the development of
industrial uses and related facilities, and further, to recognitie the unique and valuable industrial land resources existing
within the City of Anaheim. "
The project site has served as a water supply reservoir since 1935. Located east of the project site are
light industrial land uses, limited commercial uses; a wholesale /retail landscape shop located to the south,
and an Orange County Water District recharge basin, that is also used as a recreational fishing spot, west
and north of the project site. The closest residential land uses are located in the City of Placentia;
approximately one - quarter mile north of the project site and north of the Burlington Northern and Santa
Fe Railroad. The project site is zoned industrial (SP94 -1), and the Anaheim General Plan (May 2004)
designates the project site for water type land uses.
A scenic vista is defined as "a distant view through or along an avenue or opening. "` Scenic is typically
correlated with landforms, e.g., hills, valleys, mountains, sandy beaches, wildlife corridor, etc. along some
type of contiguous open space or natural landscape which can be defined by grassland, desert, shrubs, or
trees. In the City of Anaheim, these areas might occur in Anaheim Hills, and include the Deer Canyon
Preserve, or Cypress (Coal) Canyon. In the flatland areas of Anaheim, west of SR -55, it might include
areas adjacent to the Santa Ana River, such as the Burris Basin.
As stated previously, the Linda -Vista Reservoir is primarily surrounded by light industrial uses. The only
unobstructed view of the site is from Tustin Avenue which is classified as a Major Arterial according to
the Circulation Element of the Anaheim General Plan. Within the public view (see Photographs No. 1
and 10, Section 3.0), from Tustin Avenue is a flat, vacant parcel that is partially -paved upon which the
CMU buildings are located with remaining portions of the parcel covered with a thin layer of a
gravel /sand surface. The front setback is narrowly landscaped with minimal groundcover set against a 6-
foot high chain link fence with minimal vine coverage that encloses the site. Also on the site, are a
pressure regulator system enclosed by a 4 -ft. block wall, an OCWD typical monitoring well, the 400 and
555 pressure zone pump station, five single story CMU accessory buildings, and a restroom facility are
located on Site 1. A row of nonspecimen trees consisting of Silk oaks, Aleppo pines, and junipers border
the most western edge of the site. Other ornamental types of vegetation such as, Mexican Fan palms are
located on Site 1 and Coast Live Oak and other ornamentals are located on Site 2. Site 2, the northern
parcel, is composed of the existing partially buried, covered reservoir with 2 -4 feet of visibility
aboveground. There are 3 driveways off of Tustin Avenue that provide entrance to the site with the
main access from the center driveway.
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -3
Anaheim Lake, an OCWD man -made recreational fishing lake /recharge basin, is located west and north
of the Linda Vista Reservoir and is a 67 -acre engineered deep gravel pit with open water that is stocked
seasonally. The facility is currently closed and scheduled to reopen in summer 2011." A single tree, of
minimal growth, is located on the eastern border of Anaheim Lake, the property boundary adjacent to
Linda Vista's western border.
No Impact. There are no unique topographical or landscape features, properties which typically
characterize or define a scenic vista, associated with the Linda Vista Reservoir site or the immediate area.
The project site is rectangular, primarily flat, has limited landscaping, and is partially developed with
appurtenant structures associated with the existing reservoir. There are no officially designated scenic
vistas within or adjacent to the project site which is set within a densely developed light industrial setting.
There are no scenic vistas in the area, and therefore there would be no impact.

Examples of scenic resources include areas of wildlife or open space, parks, trails, landmarks, rock
outcroppings, etc. The only officially designated State Scenic Highway in the City is a 4.5 mile segment
of SR -91 from SR -55 to the Weir Canyon Road interchange located approximately 2 miles southeast of
the project area. The City's Zoning Code provides for a Scenic Corridor Overlay Zone in order to
promote orderly growth in this scenic area of Anaheim Hills. The Scenic Corridor (SC) Overlay Zone is
defined as that area lying easterly of the intersection of SR -55 and SR -91, westerly of the Riverside
County line, southerly of the Atchison, Topeka and Santa Fe Railroad right -of -way, and northerly of the
present or any future south city limits of the City of Anaheim.
The proposed project site is located in the Northeast Specific Plan Area (SP94 -1) also referred to as the
Canyon Business Area of the City of Anaheim. The Northeast Area Specific Plan Area is characterized by
various types of industrial land uses and limited commercial land use. The nearest residential land uses
are located approximately one - quarter mile north of the Linda Vista Reservoir in the City of Placentia.
No historic buildings are located within the project's footprint. The closest historical structure which is
listed on the City of Anaheim's Structures of Historical Interest is an industrial building located '/a mile west
of the project site (1401 N. Miller Street); however it is not located within the project's footprint.
No Impact. The project site is located at the existing Linda Vista Reservoir located in the City's
Northeast Specific Plan area where the underlying zone is industrial. There are no scenic resources
within the project's footprint or within the surrounding area.

Discussion
The visual character of the surrounding area is a flat terrain with a gentle slope on Site 2. Light
industrial and limited water uses, such as OCWD's Anaheim Lake is located immediately west and
north of the project site. These land uses are consistent with the Northeast Area Specific Plan (SP94 -1)
Overlay Zone. The Anaheim General Plan (May 2004) refers to this specific plan area as the "Anaheim
Canyon Business Area" or the "Canyon ".
The Community Design Element of the General Plan provides recommendations and guidance for
design policies and aesthetic enhancements that would help to continue the appeal and cohesiveness of
the Canyon. It corresponds with the Land Use Element of the General Plan, as well. Some of the
recommendations of the Community Design Element that would be applicable to the Canyon, one of
the City's key industrial areas, are the following:
• Avoid use of long, blank walls b breaking them up with vertical and horitiontal fafade articulation achieved
through stamping, colors, materials, modulation and landscaping.
• Thoroughly screen and enclose all outside storage areas through the use of perimeter walls and landscape
treatments
• Use abundant landscaping to minimitie views of surface parking, storage and service areas.
• Where practical, underground or screen utilities and utility equipment or locate and sitie them to be as
inconspicuous as possible.
•
Reduce the noise, traffic and visual impacts of service, delivery, parking and loading areas by locating them as far
as practical from adjacent sensitive uses (e.g., residential and commercial areas), from the street, sidewalk or
building entrances.
Preliminary landscape plans (refer to Figure 5) for the proposed project demonstrate a landscape setback
varying in width from 4 -ft. to 19 -ft. along the front of Site 1 and Site 2 bordering the west side of Tustin

create a layered landscaped appearance. Proposed trees to be installed will be consistent with the area
(e.g., Canary Island Pines, Silk Oaks, etc.) and will assist to screen the view of the new reservoir tank
from the public's view from Tustin Avenue. The aforementioned trees are consistent with the area.
They exist at the Linda Vista Reservoir site and on Miraloma Avenue, just west of Tustin Avenue. Also,
an 8 -ft. block wall with architectural columns and a cap trim of contrasting color will replace the existing
chain link fence on Site 1 along Tustin Avenue. Vines will cover the block wall in order to prevent
opportunities for graffiti. The existing chain link fence on Site 2 will be replaced with a new 8 -ft. high
chain link fence. Vines will be installed on the chain link fence to assist in site screening. Currently, the
accessory CMU buildings, utility equipment, and the OCWD monitoring well are not screened and within

the block wall and trees. A sidewalk will also be installed within the parkway of the project site on the
west side of Tustin Avenue in front of the project site; currently there is not a sidewalk on Tustin
Avenue.
The new concrete tank will replace the existing partially buried reservoir built in 1935 and will be visible
up to a height of approximately 32.5 -ft. A portion of that height will be screened by the proposed 8 -ft.
block wall and the evergreen pine trees and canopy trees that will be installed within the front setback
and behind the block wall. The Anaheim Municipal Code does allow a structural height up to 60 feet, so
the project's height is consistent with the Zoning Code. To minimize the visibility of the tank, it will be
painted an earth tone color and will have architectural column features of contrasting color. The earth
tones colors will be designed to blend in with the area. Trees will also be planted along the southern
border of Site No. 1, in order to buffer the view of the tank from Miraloma Avenue. The access road for
site maintenance enters from Tustin Avenue and curves around along the western side of the tank;
thereby creating less noise, visual impact, and disturbance to the surrounding businesses in the area.
Less- Than - Significant Impact. The visual character of the site will not be degraded. The existing
partially buried reservoir built in 1935 will be replaced with a new tank built to current building seismic
standards. Approximately 32.5 feet of the tank's height will be visible, but with architectural features and
earth tone colors that will blend in with the surrounding area. Tall, evergreen pine trees and canopy type
trees will be installed within the front setback located on the west side of Tustin Avenue in front of the
project site. Improvements to the site include a new sidewalk to provide safer access for pedestrians.
Currently there is no sidewalk on Tustin Avenue. Landscaping within the front setback will include
installation of a layered appearance of drought tolerant landscaping. A block wall will replace the existing
chain link fence. Also, attention to the new structure's design compatibility with its existing surroundings
will help to maintain the existing visual quality of the site. Deliveries to the site will be made at the rear
of the site and would be obscured by the proposed block wall. Following implementation of these design
features, the visual quality of the site will be enhanced and not degraded, and therefore, its impact will be
less than significant.

Existing Air Quality Conditions
The project is located in the City of Anaheim in the County of Orange and is within the South Coast Air
Basin (basin). To the west of the basin is the Pacific Ocean. To the north and east of the basin are the
San Gabriel, San Bernardino, and San Jacinto mountains, while the southern limit of the basin is the San
Diego County line. The basin consists of Orange County, all of Los Angeles County except for the
Antelope Valley, the non - desert portion of western San Bernardino County, and the western and
Coachella Valley portions of Riverside County. The air quality in the basin is impacted by dominant
airflows, topography, atmospheric inversions, location, season, and time of day.
Dominant airflows provide the driving mechanism for transport and dispersion of air pollution. The
mountains surrounding the region form natural horizontal barriers to the dispersion of air contaminants.
Air pollution created in the coastal areas and around the Los Angeles area is transported inland until it
reaches the mountains where the combination of mountains and inversion layers generally prevent
further dispersion. This poor ventilation results in a gradual degradation of air quality from the coastal
areas to inland areas. These inversions, in conjunction with calm winds, trap pollutants near the source.
Local Air Quali
The local air quality can be evaluated by reviewing relevant air pollution concentrations near the project
area. For evaluation purposes, the SCAQMD has divided the basin into 36 Source Receptor Areas
within the Basin operating monitoring stations in most of the areas. These Source Receptor Areas are
designated to provide a general representation of the local meteorological, terrain, and air quality
conditions within the particular geographical area. The project is within Source Receptor Area 16.
SCAQNID operates an air monitoring station in Source Receptor Area 16.
Federal Regulations
Air quality is regulated by Federal, State, Regional, and Local standards. Per the Clean Air Act, the
United States Environmental Protection Agency (USEPA) is responsible for setting and enforcing the
National Ambient Air Quality Standards (NAAQS) for criteria air pollutants. There are seven criteria air
Linda Vista Tank and Pump Station Project - Draft Initial Study /Mitigated Negative Declaration 4 -9
pollutants: nitrogen dioxide (NOx), ozone (0 particulate matter (including both PM10 and PM2.5),
carbon monoxide (CO), sulfur dioxide (SOx), and lead. The project site is located within a Federal and
State designated nonattainment area for ozone, nitrogen dioxide, PM2.5, and PM10 and is in
attainment /maintenance for carbon monoxide.
Ozone is a secondary criteria pollutant, meaning that it is not directly emitted. It is a gas that is formed
when volatile organic compounds (VOCs) (also referred to as reactive organic gases) and nitrogen
dioxide undergo photochemical reactions that occur only in the presence of sunlight. Ground -level ozone
is the primary constituent of smog. The primary source of VOC emissions is unburned hydrocarbons in
motor vehicle and other internal combustion engine exhaust. Particulate matter tends to occur primarily
in the form of fugitive dust. The principal sources of dust in the urban areas are grading, construction,
disturbed areas of soil, and dust left by vehicles on roadways. PM10 is generally emitted directly as a
result of mechanical processes that crush or grind larger particles or from the re- suspension of dusts,
most typically through construction activities and vehicular travels. PM2.5 is directly emitted in
combustion exhaust and formed in atmospheric reactions between various gaseous pollutants including
nitrogen dioxide, sulfur oxides (SOx), and VOCs.
Carbon monoxide (CO) is a criteria pollutant that appears as a colorless and odorless gas which, in the
urban environment, is associated primarily with the incomplete combustion of fossil fuels in motor
vehicles. High levels of CO commonly occur near major roadways and freeways. Currently, CO levels in
the project region are in compliance with the State and federal one -hour and eight -hour standards. Each
standard has a different definition, or `form' of what constitutes attainment, based on specific air quality
statistics. For example, the Federal 8 -hour carbon monoxide (CO) standard is not to be exceeded more
than once per year; therefore, an area is in attainment of the CO standard if no more than one 8 -hour
ambient air monitoring values exceeds the threshold per year. In contrast, the Federal annual PM,-
standard is met if the three -year average of the annual average PM, concentration is less than or equal to
the standard.
Nitrogen dioxide (NOx) is a red -brown pungent gas and is toxic to various animals and to humans
because of its ability to form nitric acid with water in the eyes, lungs, mucus membranes, and skin. Motor
vehicle emissions are the main source of NOx in urban areas. SOx is the family of sulfur dioxide gases
and is formed during combustion of motor fuels. Another primary contributor of SOx emissions is fossil
fuel combustion for generating electric power. Lead is a metal that can be found in very small particles in
the atmosphere. When USEPA adopted the lead standard for gasoline in 1978, it was estimated that over
90 percent of ambient lead concentrations were attributable to the previous use of lead in gasoline.
Although lead from gasoline no longer poses an air quality problem, lead emissions from remaining
industrial sources such as battery recycling, lead smelters, cement and glass manufacturing, metal mining
and the use of non - leaded fuel in certain general aviation applications (but not in commercial passenger
aircraft) can still pose "hot spot" problems in a few locations.
In order to attain and maintain the Federal standards for criteria pollutants, the USEPA requires each
State with federal nonattainment areas to prepare and submit a State Implementation Plan (SIP) that
demonstrates the means to attain and maintain these standards.
State Regulations
The California Air Resources Board (CARB) is part of the California EPA and is responsible for the
coordination and administration of both federal and State air pollution control programs in California.
CARB conducts research; sets the California Ambient Air Quality Standards (CAAQS); compiles
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 410
emission inventories; develops suggested control measures; provides oversight of local programs;
prepares the SIP (adopted September 27, 2007) which outlines the plan for regions in nonattainment to
achieve attainment of Federal standards for criteria pollutants; is responsible for developing a Scoping
Plan to lower the State's Green House Gas Emissions (GHG); and oversees the Toxic Air Contaminants
Program (TACs) and Hotspots Program. A list of TACs was established in 1983, through AB 1807, to
reduce exposure to air toxins. Air toxins include substances such as, benzene, vinyl chloride, etc. (the
complete list is available through CARB website: http:// www. arb .ca.gov /toxics /id /tachst.htm The Air
Toxics "Hot Spots" Information and Assessment Act was established in 1987, and "requires stationary
sources to report the types and quantities of certain substances routinely released into the air. The
program requires notification to nearby residents of significant air emissions risks.
Regional Regulations
Regionally, the project is under the jurisdiction of the South Coast Air Quality Management District
( SCAQMD) which is the agency principally responsible for comprehensive air pollution control in the
basin. SCAQMD, a regional agency, works directly with local governments, and cooperates actively with
all Federal and State government agencies. SCAQMD develops rules and regulations; establishes
permitting requirements for stationary sources; inspects emissions sources; and enforces such measures
through educational programs or fines, when necessary. The SCAQMD has adopted the 2007 Air
Quality Management Plan that sets forth a comprehensive program that will lead the region into
compliance with Federal 8 -hour Ozone and PM2.5 air quality standards. EPA set a new one -hour
standard for nitrogen dioxide at a level of 100 parts per billion on January 25, 2010, which became
effective April 12, 2010. EPA expects to identify or designate areas not meeting the new standard, based
on the existing community-wide monitoring network, by January 2012. This project will comply with the
standards set forth in the 2007 Air Quality Management Plan.
Local Regulations
In addition to the regulations stated above, the project will comply with policies relative to emissions
reduction that are stated on page G -18 of the Green Element of the City of Anaheim General Plan (May
2004), including but not limited to: Policy 2) Regulate construction practices, including grading, dust
suppression, chemical management, and will encourage pre - determined construction routes that
minimi dust and particulate matter pollution.
Thresholds of Significance
The State CEQA Guidelines states that the significance criteria established by the applicable air quality
management or air pollution control district may be relied upon to make the above determinations. The
SCAQMD has established significance thresholds to assess the regional and localized impacts of project
related air pollutant emissions. Table 1 presents the most current significance thresholds including
regional daily thresholds for short -term construction and long -term operational emissions; maximum
incremental cancer risk and hazard indices for TACs; and maximum ambient concentrations for exposure
of sensitive receptors to localized pollutants. A project with daily emission rates, risk values, or
concentrations below these thresholds is generally considered to have a less than significant effect on air
quality.

° Ambient air quality threshold based on SCAQMD /ARB.
Conformance to Applicable Air Quality Plans
The two principal criteria for conformance to the SCAQMD's Air Quality Management Plan (AQMP)
are: (1) whether the project will not result in an increase in the frequency or severity of existing air
quality violations, cause or contribute to new violations, or delay timely attainment of air quality
standards and; (2) whether the project will exceed the assumptions in the AQMP (SCAQMD 1993).
Resulting calculations from the URBEMIS program (Urban Emissions, See Appendix A, Air Quality
Impact Analysis) that was run for construction emissions, demonstrates that the project would not result
in an increase in the frequency or severity of existing air quality violations, cause or contribute to new
violations, or delay timely attainment of air quality standards. Also, the proposed project would not
generate significant operational emissions, and therefore would not conflict with assumptions in the
AQMP. The project would conform to the AQMP; there would be no impact.
Conformance with the region's AQMP implies conformance with the SIP as the State's SIP incorporates
the latest version of the 2007 AQMP which focuses on how the basin will achieve attainment of the
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 412
Federal 8 -hour standard for ozone and the Federal standard for PM2.5. Since Table 3 demonstrates that
the project will not exceed SCAQMD thresholds, then the project is consistent with applicable air quality
management plans.
Construction Emissions
Development of the facility would require the use of heavy equipment during construction, which would
create some level of temporary emissions. Air pollutants would be emitted by off -road and on -road
construction equipment and worker vehicles; fugitive dust would be generated during demolition and
grading on the project site. Onsite temporary emissions principally consist of exhaust emissions (NO.,
SO„ CO, VOC, PM „„ and PM, 5 ) from heavy -duty construction equipment, motor vehicle operation, and
fugitive dust (mainly PM,, from disturbed soil. Other construction activities that emit pollutants include
painting, surface coating, and asphalt paving operations. Construction emissions were calculated using
URBEMIS version 9.2.4. Offsite temporary emissions are caused by motor vehicle exhaust from delivery
vehicles, worker traffic, and road dust (PM,,, and PM,
Grading /Site Preparation
It is expected that the excavation for construction of the concrete pad for the new tank will be 10 feet
deep. Even deeper trench excavations will be required for piping entering and exiting the reservoir.
Much of the excavated material is expected to be sand, which is not associated with much fugitive dust.
Therefore, the URBEMIS default fugitive dust emission rate of 20 pounds per day was used. Excavation
for the new tank and piping is expected to require approximately 2,000 cubic yards of soil removal.
Approximately 700 cubic yards will be backfilled and recompacted around the lower wall of the new tank.
The remaining 1,300 cubic yards of excavated material can be used for backfill of the existing tank during
demolition work.
Existing Reservoir Demolition and Backfill
Although minimal demolition is required prior to construction, the existing reservoir will be demolished
after the new reservoir and pump station are placed in service. Options available include:
• Partial demolition of the reservoir, or
• Full demolition of reservoir.
The decision regarding the extent of the reservoir demolition work performed as part of the current
construction contract depends on funding availability and the probability of constructing a future water
storage tank and /or a water treatment plant. For purposes of this analysis, a worst -case scenario of full
demolition of reservoir is assumed.
Demolition of reservoir: The existing reservoir is approximately 250 feet by 250 feet. The concrete floor
is approximately 0.5 feet thick. Concrete removal would be approximately 31,250 cubic feet (1,200 cubic
yards). It is assumed demolition of reservoir would occur over a period of ten days.
Backfill/grading of reservoir: It is estimated approximately 23,000 cubic yards of fill would be required
to backfill the existing reservoir. Approximately 5,000 cubic yards of excess material will be generated
from the new reservoir construction. An additional 10,000 cubic yards appears to be available from the
Anaheim Lake dredging spoil piles (which is adjacent to the site), leaving a deficit of 8,000 cubic yards to
be imported from other sources (this material may be obtained from a site near Santa Ana River south of
Imperial Highway, assuming ten miles round trip distance). To estimate fugitive dust from
backfill/grading, the "low” level of detail was used in URBEMIS, dividing 23,000 cubic yards by 10 days,
for 2,300 cubic yards of fill per day.

As shown in Table 2, project construction mass daily emissions would be less than the SCAQMD
thresholds.
In order to address particulate matter originating from dust emissions related to construction, the City of
Anaheim will comply with SCAQMD Rule 403 concerning fugitive dust and shall include in the grading
plans the requirement that:
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated N egative D eclaration 4 -14
The Contractor, during the period ofsoil excavation and export (1) water the ac gn
atleast 1 t[me per day ormore often ifnecessaty to prevent visible dust plumes from leaving the
project site and (2) water the excavated soil to prevent visible dustplumes when loading soil into
trucks for export from the site. This is a project design feature.
Operational Emissions
The project consists of upgrading and replacing existing facilities and developing new facilities to meet
future demands. Operation of the project would result in the same air pollutants as on the existing
project site. These emissions likely consist of vehicle emissions from any employee trips to the project
site. There is an existing emergency generator onsite; neither the diesel fuel tank nor the generator would
be replaced as part of the project. Any new equipment or facilities onsite would be more efficient than
the existing equipment or facilities; therefore, operational emissions could be less than existing.
Operational emissions are less than significant and would not violate any air quality standard or
contribute substantially to an existing or projected air quality violation. Plant operations would generate
a negligible quantity of criteria pollutants. Emissions would be limited to those from a few vehicle trips
per day for an operator or technician to check on plant operations. Therefore, no quantitative estimate
of operational emissions is required.
Less- Than - Significant Impact. The project as proposed would require earth movement and
construction activities; however, calculation results indicate that SCAQMD thresholds for construction
emissions would not be exceeded. Design features including the feature stated above, will be consistent
with AQMD's Best Available Measures under Rule 403 for fugitive dust during construction, and will be
followed and incorporated within the grading plans. Operational impacts are expected to be negligible
due to the size of the proposed project, the type of use, and the minimal increase in traffic generated by
the project. Based on this information, the project would comply with all applicable air quality
management plans and would result in a less than significant impact.

The project is located in the basin which has non - attainment levels of the criteria pollutants PM2.5 (fine
particles 2.5 microns or smaller in diameter), PM10 (suspended particles of both fine and dust particles
smaller than 10 microns in diameter but larger than 2.5 microns in diameter), nitrogen dioxide, and
ozone. The SCAQMD has established significance thresholds for these criteria pollutants for both
construction and operational activities. The air quality analysis that was conducted indicates that these
thresholds will not be exceeded (see Table 2). Standard measures for air quality, such as dust control
measures during grading and earth moving construction activities, will be implemented into the project as
a design feature and incorporated into the grading plans.
Due to the size of the project and the fact that the project will not generate any significant increase in
vehicular traffic, and the regulation of the proposed stationary equipment by the SCAQMD, the project
is not expected to exceed thresholds of criteria pollutants individually or cumulatively.
Less - Than - Significant Impact. The air quality analysis that was conducted for this project indicates
that significance thresholds for criteria pollutants will not be exceeded during construction and during
project operation.

Surrounding existing uses are primarily light industrial, water uses and limited commercial. Residential
land uses are located in the City of Placentia, approximately' /4 mile north of the project site and north of
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 416
the BNSF railroad. Receptors are those locations where persons may be exposed for one hour or more.
Sensitive receptors would include residences, any senior facilities, hospitals, or schools.
The Air Toxics "Hot Spots" Information and Assessment Act of 1987 is under the jurisdiction of the
California Air Resources Board and requires stationary sources to report the types and quantities of
certain substances routinely released into the air in order that any health risks to nearby residents or
sensitive receptors, are identified and notified of any significant risks. Construction equipment would
emit diesel particular matter, which is a carcinogen. However, use of construction equipment would be
temporary and determination of risk is considered over a 70 -year exposure period. As the nearest
receptor would be the residential neighborhood located '/4 mile north, exposure to diesel particulate
matter is considered to be less than significant.
A CO (carbon monoxide) hotspot is an area of localized CO pollution that is caused by severe vehicle
congestion on major roadways, typically near intersections. The proposed project would generate a very
small number of daily trips; so there would be no potential for a CO hotspot. There would be no
impact and no exposure of sensitive receptors to project - generated local CO emissions.
Operations Emissions
Operational emissions for the proposed project would be minimal. The sources would be the few vehicle
trips made by persons checking on operations of the plant and the distribution system. The impact would
be less than significant.
Less- Than - Significant Impact. Construction and operational activities will not result in air pollutants
that exceed SCAQMD thresholds or State standards. Based on the above air quality analyses, exposure
of substantial pollutant concentrations to any sensitive receptors would be less than significant.

Potential sources of odor could occur as a result of construction due to construction- related equipment
exhaust and asphalt and architectural coatings. Standard construction requirements would be imposed
upon the project to minimize odors. Any construction- related odor emissions would be temporary,
short-term, and intermittent in nature. Architectural coatings with a low VOC (Volatile Organic
Compounds) content will be used in order to minimize odors and emissions during construction.
Land uses such as industrial manufacturers, chemical treatment plants, dairies, landfills, refineries,
wastewater treatment facilities, and water recycling facilities do have the potential to generate some
degree of objectionable odor perceivable by the surrounding area. The proposed water reservoir will be
enclosed and is not expected to generate any odors. The primary chemical used on site is a 12.5%
solution of Sodium Hypochlorite (similar to household bleach).
The South Coast Air Quality Management District, SCAQMD, is the regional agency who regulates air
pollutant emissions, including foul odors, from stationary sources under Rule 402. The reservoir would
be subject to these regulations. SCAQMD has a hotline, 1- 800 - CUT -SMOG, that would receive

complaints relative to foul odors. If six or more complaints from the public were received and verified
by SCAQMD, then a nuisance violation cut be issued and the matter would need to be addressed under
conditions set by SCAQMD staff.
Less- Than - Significant Impact. Construction odors could be minimized with the imposition of
standard construction requirements and protocols. No operational emissions are expected. Any impacts
from offensive odors would be temporary and less than significant.

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 Game or U.S. Fish and Wildlife Service?
Discussion
Sensitive wildlife and plant species are those that are candidates, proposed, or listed as threatened or
endangered by the U.S. Fish and Wildlife Service (USFWS) or the California Department of Fish and
Game (CDFG), and in the case of plants, those that are considered sensitive species by the California
Native Plant Society (CNPS). The City contracted Psomas biologist, Dr. Brad Blood, who performed a
data search of sensitive wildlife and plants species that have historically occurred within the project area
or have the potential for occurrence. This search included records from the California Natural Diversity
Database (CNDDB) (2010) and the California Native Plant Society Inventory of Rare and Endangered
Vascular Plants of California (2004). A full list of resources reviewed can be found in the biological
resources evaluation that was completed for the project (Appendix B).
In order to complete the field survey of plants and wildlife present at the site, Dr. Blood made three visits
(April 15, 2010, June 22, 2010, and October 5, 2010) to the Linda Vista Reservoir. According to the
survey, no endangered, threatened, or candidate species were observed. Present at the site was a rookery,
or a colony, of Great Blue Herons (Ardae herodias) nesting within the onsite Aleppo pines (P.
halepensis) that border the western edge of Site 1. The California Department of Fish and Game has
listed a rookery of great blue herons on their "Special Animal' List. The Aleppo pine is not listed as
endangered or threatened, or sensitive species on any Federal or State of California lists. This nesting
location has been previously reported in the CNDDB. The biological evaluation that was completed for
the project indicates that during the April and June surveys, at least 3 of the nests appeared to be active.
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -18
The site contains no sensitive plant species. The site has limited vegetation, primarily consisting of
ornamental landscaping; some of which will be removed (e.g., Mexican fan palms approximately 7 feet in
height, etc.) in order to accommodate the improvements to the site; the removal of which will comply
with the provisions of the Migratory Bird Treaty Act (MBTA). The MBTA prohibits actions that pursue,
hunt, take, capture, kill, attempt to take, possess, offer for sale, offer to purchase, deliver for shipment,
deliver for transportation, or cause to be carried by any means or in any manner, any migratory bird
included in the terms of the Convention for the protection of migratory birds or any part, nest, or egg of
any such bird" (16 U.S.C. 703) during the nesting season which occurs from February through July 31
and sometimes trails into mid- August. The Aleppo pines that are being utilized as a rookery are a
nonnative pine tree that can grow to a height of 30 -60 feet and thrive under harsh conditions such as
poor soil and /or drought. The pines are not listed on any Federal or State lists for sensitive species. The
great blue heron as previously mentioned, is listed on the California Department of Fish & Game's
"Special Animal" list. This essentially means that numbers for this species are not low enough to be
considered at the endangered, threatened, or candidate levels, but their rookeries are under watch by the
Department of Fish & Game as habitat for this species, which can occur within a row or strand of trees
of tall height, can be subject to elimination due to development. City Public Utilities Environmental staff
has been in consultation with the California Department of Fish & Game and the Migratory Bird Treaty
Section of the U.S. Fish & Wildlife Service regarding the rookery and the potential project impacts.
The Great Blue Heron is a species that occurs throughout the United States. In California, the species
can be found mainly around coastal areas, bays, lakes, and rivers. In Orange County, the species is
known to occur in areas that include but are not limited to the Santa Ana River, Warner Basin, Anaheim
Lake (located immediately west of the Linda Vista Reservoir project site), Newport Back Bay, and the
Bolsa Chica Wetlands. The heron typically feeds on fish, but is also known to prey on other birds,
reptiles, rodents, and amphibians. It usually nests in colonies of tall trees and begins nest building after
February. The great blue heron is not a migratory bird in the strictest sense of the term, meaning it may
leave its nest but may not migrate south outside of our local coastal areas as with other migratory birds.
The herons may return to a nesting site again in November or late December "'following the bird nesting
season. It is not known whether the same herons or other herons will utilize the nests left in their
rookery.
The project will not directly adversely affect any candidate, sensitive, or special status species, but as the
rookery of great blue herons that is present on the site is considered, a "Special Animal ", City
Environmental staff have been working with the Department of Fish & Game to ensure that project
measures are in place to protect the rookery to the greatest extent of the project, as is possible. The
habitat for rookery will not be eliminated as a result of the project, but noise from heavy construction
could impact the nesting season where, nest abandonment could occur. Additionally, the Federal
Migratory Bird Treaty Act prohibits the modification of habitat belonging to a migratory bird. The
Treaty prohibits the "take" of an egg or bird during the bird nesting which could be a result of
disturbance to the nests of migratory birds. Noise from heavy construction activities could result in birds
abandoning their nests, although, it has been noted that the herons seem to also "tolerate human
presence" and "their numbers appear to be increasing in Orange County" "'.
Construction on the project will begin in August 2011, outside of the nesting season for the great blue
heron and will last for approximately 16 months. Some phases of construction, which at times is within
25 feet of the existing inactive nests, could generate noise levels in the 90 -100 dBA range (refer to
Section 4.13, Noise, of this document). In order to offset any potential impacts from construction that
could gccur during the nesting season for 2012, the following mitigation measure will be implemented:
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -19
MM1: Following August 1, 2011 and periodically thereafter during the month of
August, City Environmental Staff will monitor the nests of the great blue
he-ton within the onsite tookery in order to determine the presence of any
active nests within the Aleppo Pine trees located along the western perimeter
ofthe Linda Vista Resetvoit prop ett When ithas been determined that the
nests are inactive or empty of eggs, bird netting will be applied over the
Aleppo Pine trees as a deterrent to any impacts to the herons during the 2012
nesting season. The netting will be removed following the completion ofthe
nesting season, or approximately at the end of July 2012. Following removal
of the bird netting, 2 Aleppo pine trees, of trees of similar kind and height,
will be planted within the existing rookery. City Environmental staff will
forward a summary of their actions to the California Department ofFish and
Game, with a copy to the U.S. Fish & Wildlife Service.
As previously discussed in this section, great blue herons have been observed onsite at the adjacent
Anaheim Lake property, and are also present at Warner Basin — also a seasonal, recreational fishing lake,
and along portions of the Santa Ana River. These potential nesting sites are all within, at most, 1 mile of
the Linda Vista Reservoir site. Once the bird netting is removed from the Aleppo pine trees at Linda
Vista Reservoir, following project construction, the herons could once again utilize these trees.
Less - Than - Significant - Impact with Mitigation Incorporated. Three observation surveys of the site
indicate there are no endangered, threatened, or sensitive wildlife or plant species on site. A rookery of
great blue herons, a migratory bird, and a species listed on the Department of Fish and Game's Special
Animal List, and three active nests were present during the bird nesting season. Construction on the
project will begin in mid or late August of 2011; following the migratory bird breeding /nesting season
and will last until approximately December of 2012. This period would be during the potential
breeding /nesting season of 2012. In order to prevent potential impacts to the heron's nests, bird netting
will be applied to the Aleppo pine trees in the vicinity of the new tank. This is a mitigation measure,
MM1, that will remain in place until the end of the breeding nesting season or July 2012, and result in
impacts that are less than significant.

The project site is not located in any of Anaheim's five Historic Districts nor listed on the City's
"Qualified Historic Structures /Citywide Structures of Historical Interest" list. A historical records search
(See Appendix C) was conducted by the SCCIC and surveyed the project site as well as an area
encompassing a '/2 -mile radius around the site. The survey consisted of a review of the California Points of
Historical Interest, the California Historical Landmarks, the California Register of Historical Resources, the National
Register of Historic Places, and the California State Historic Resources Inventory. One archaeological site (30-
000430) and one cultural resource (30- 176798) were identified within the 1 /2 -mile radius of the site, but
no resources were located within the footprint of the project site.
A review of historic USGS maps indicated that by 1896, the project area was largely undeveloped and is
characterized by one railroad line and one marked road. In 1935, Site 2, the most northern portion of the
project site, was used for a water reservoir most likely in support of the agricultural activities that largely
characterized the area. Site 1 was undeveloped until 1992 when the 400 -Zone pump station was added.
Five small buildings and an office trailer have been added to the site since that time.
The existing roofed, concrete -lined reservoir may be removed as part of the project. Based on resources
located with a 1 /2 -mile radius of the project site, as referenced in the SCCIC Report mentioned above,
there is the potential that unknown cultural resources could be encountered during excavation. As part
of the project, a design feature will be incorporated into the grading and construction plans that
will require construction operations to cease and the contractor will be required to notify a
licensed archaeologist in the event that unknown historic resources are encountered during
construction activities.
Less - Than - Significant Impact. A search of historical records did not result in the identification of any
historical resources within the project site; however, resources were identified within a '/2 -mile radius. In
the event that unknown resources are encountered during construction activities, all work will cease until
a licensed archaeologist is summoned to make an assessment of the historical resource.

Mines and Geology Special Publication 42
Discussion
The Alquist -Priolo Earthquake Act was enacted in 1972 and revised in 1999 to the Alquist -Priolo Special
Studies Zones Act. Its purpose is to identify whether active fault zones for surface fault rupture hazards
are within the footprint of new construction; especially when these structures will be inhabited. These
types of faults are potentially hazardous.
The project site is not located within any active Alquist -Priolo Earthquake Fault Zone for surface fault
rupture hazards. No active or potentially active faults with the potential for surface fault rupture are
known to be present within the project's footprint.
NMG Geotechnical, Inc., the geotechnical consultant for the Linda Vista Reservoir and Pump Station
project, performed a site specific earthquake risk analysis using the software program, EZFRISK, version
7.32 (Appendix D). EZFRISK is used to calculate the probability of earthquake ground shaking at the
surface or in the bedrock beneath a site based on the location of surrounding faults. The program
determined that the closest active fault to the site is the Puente Hills Fault.' The Puente Hills Fault runs
from northern Orange County to downtown Los Angeles; north of the Whittier Fault and is a blind
thrust fault that was "discovered" in 1999.°' This fault is located approximately 5.5 miles east - northeast
of the Linda Vista Reservoir. According to the NMG study, "the Puente Hills buried thrust fault is the
controlling fault with a maximum moment magnitude of 7.1 to 7.2M." The maximum moment
magnitude is a measure of the size of the earthquake in terms of the energy released.
The Whittier - Elsinore Fault was also indicated by EZFRISK as another active fault (Alquist- Priolo) that
would be closest to the project site. It is located approximately 4 miles east - northeast of the Linda Vista
Reservoir project location. This fault is not within the project's footprint.
Design and construction recommendations were formulated following NMG's seismic- hazard and soil
borings analyses for the proposed 4MG, 38 -ft high and 148 -ft in diameter tank to be installed at 5 -ft±
below finish grade (refer to Appendix D for specific details). The analysis determined that "primary
Linda Vista Tank and Pump Station Project — Draft I St udy /Mitigated Negative Declaration 426
ground rupture would be considered nil or slight" and that "the primary seismic hazard for the site is
ground shaking due to a future earthquake on one of the major regional active faults." (Appendix D).
However, as California is prone to earthquake activity, including those resulting from subsurface thrust
faults (which are unmapped); all construction will be required to comply with seismic design criteria
under the existing 2007 CBC for Site Class "D ". As the proposed facility will comply with the 2007 CBC
site design standards, the potential to expose people or structures to substantial adverse effects is low.
Less- Than - Significant Impact. There is no record of active fault activity within the project's
footprint and the proposed unstaffed facility would comply with existing CBC seismic design standards.
Therefore, any impacts would be less than significant.

Discussion
The City is located in a seismically active general area and the project site could be subject to moderate to
strong ground shaking in the event of an earthquake resulting from an unknown subsurface thrust fault
or surface faults located in the southern California region. NMG Geotechnical, Inc. was contracted to
perform an estimation of peak and spectral accelerations for the Maximum Considered Earthquake
(MCE) ground motion values for all active faults within a 60 -mile radius of the project site. This
information was coupled with the data obtained from additional analyses completed as referenced in
Section a) above.
The proposed project may expose on -site structures to significant seismic hazards (e.g., shaking) if an
earthquake occurs along these faults. Development of the proposed facility would require adherence to
existing codes and regulations, such as the 2007 CBC, the ASCE Standard 7 -05, the U.S. Geological
survey programs, and the 2002 California Fault Database. The proposed project would be required to
adhere to the recommendations set forth in the geotechnical study (Appendix D) to ensure that the
proposed facility and associated infrastructure would be adequate to withstand ground shaking.

Seismic - related ground failure, including liquefaction?
Discussion
Soils subject to liquefaction are those saturated with water; particularly in the case of sandy soil. The
State of California Seismic Hazard Zone Map, Orange Quadrangle (April 15, 1998) indicates that the
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4_27
project site is located in an area subject to liquefaction. When there is shaking, as in the case of an
earthquake, the strength of soil can be reduced as it becomes saturated, particularly if the water pressure
within the soil becomes high and density of the soil is low or loose.
NMG Geotechnical, Inc. was contracted to do the geotechnical analysis for the proposed water tank
installation (Appendix D). Four hollow- stem -auger borings were performed for this analysis. "The
borings were drilled through fill and alluvial deposits to a depth of approximately 26.5 to 51.5 ft below
existing grade." (Appendix D). NMG's analysis indicates that the project "site has deep groundwater
conditions and relatively dense soils and as a result, the liquefaction for the site is considered to be
negligible."
Less- Than - Significant Impact. No significant impact would result as the geotechnical analyses
performed for the project indicates that groundwater conditions are deep and the soil is relatively dense.
If any liquefaction did occur, its impact would be considered negligible.

Discussion
The project site is located on a relatively flat surface. Most of the site will be paved and any permeable
surfaces will be landscaped or ground treatment (i.e., hydroseed, gravel, mulch) will be applied. The
project contractor would be required to provide an erosion control plan to be followed during the
grading and construction phases and would be approved by the Building Division of the City of Anaheim
Planning Department.
Less - Than - Significant Impact. Implementation of the proposed project would not result in
substantial soil erosion or the loss of topsoil. Significant erosion typically occurs on steep slopes where
stormwater and high winds can carry topsoil down hillsides. The relatively flat nature of the project site
precludes it from being susceptible to erosion. In addition, landscaping and other treatments would limit
the amount of exposed soil and would thus minimize the potential for soil erosion. During construction,

standard codes and conditions relating to stormwater runoff and dust control would minimi the
potential for erosion. Therefore, the project would have a less than significant impact on soil erosion.

The geotechnical report that was prepared for this project, (Appendix D) indicates that the existing fill
and soils of the project site are classified as "medium dense to dense ". Approximately, the upper 5 -ft of
the soil is from fill and the report recommends that it be removed and the area be recompacted.
Additionally a 5 -ft thick fill blanket is recommended for the location of the new water tank. A geologist
will be on site to monitor this phase of construction and make any needed, additional recommendations.
Less - Than - Significant Impact. The geotechnical report (Appendix D) makes recommendations
relative to the existing fill in order to accommodate the new reservoir. These recommendations will be
included on the grading/ construction plans and a geologist will be onsite to monitor construction
activities during this phase of development. The project will comply with all grading and building
requirements identified in the project geotechnical report which would minimize the potential for
impacts. Therefore, the proposed project in this regard would be less than significant.

Expansive soils are those that expand when water is added to them. Typically, these types of soils
contain clay minerals that absorb water. An expansion test evaluation, the R -value and Expansion Index
(EI), was performed by NMG Geotechnical, Inc. (See Appendix D). The expansion index of the soil was
determined to be "0" or have "very low" potential for expansion and the R -value resulted in an R -value
of 72. Both results indicate, according to NMG's geotechnical study, "to have negligible expansion
potential."
No impact. According to the testing that was done for expansive soils, the site soils contain only
negligible expansion potential; therefore there would be no impact.

Generate greenhouse gas emissions, either directly or
El
indirectly, that may have a significant impact on the
environment?
Discussion
Gases that trap heat in the atmosphere are referred to as greenhouse gases. The effect is analogous to
the way a greenhouse retains heat. Greenhouse gases as defined by AB 32 include the following gases:
carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
Natural processes and human activities emit greenhouse gases. The presence of greenhouse gases in the
atmosphere affects the earth's temperature. It is believed that emissions from human activities, such as
electricity production and vehicle use, have elevated the concentration of these gases in the atmosphere
beyond the level of naturally occurring concentrations.
Individual greenhouse gas compounds have varying global warming potential and atmospheric lifetimes.
Carbon dioxide, the reference gas for global warming potential, has a global warming potential of one.
The calculation of the carbon dioxide equivalent is a consistent methodology for comparing greenhouse
gas emissions since it normalizes various greenhouse gas emissions to a consistent metric. Methane's
warming potential of 21 indicates that methane has a 21 times greater warming affect than carbon dioxide
on a molecule per molecule basis. A carbon dioxide equivalent is the mass emissions of an individual
greenhouse gas multiplied by its global warming potential.
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -30
Recent state legislation such as AB32 and SB 375 has set goals for decreasing greenhouse gas (GHG)
emissions thereby requiring an analysis of potential impacts to global climate change and GHGs. SB 97
required the California Office of Planning and Research (OPR) to amend the CEQA Guidelines to
address impacts and provide guidelines for the analysis of GHG. The amendments to the Guidelines
became effective on January 1, 2010. Greenhouse gas mitigation measures are referenced in general
terms, but no specific measures are championed. The revision to the cumulative impact discussion
requirement (CEQA Guidelines, Section 15130) simply directs agencies to analyze greenhouse gas
emissions in the environmental document when a project's incremental contribution of emissions may be
cumulatively considerable, however it does not answer the question of when emissions are cumulatively
considerable. It is up to the Lead Agency to determine that, in fact, the GHGs emitted by a project do
not conflict with any policy or plan designed to decrease emissions.
It is accepted as very unlikely that any individual development project would have GHG emissions of a
magnitude to directly impact global climate change; therefore, any impact would be considered on a
cumulative basis. For purposes of the CEQA analysis for the proposed project, and considering the most
recent proposed revisions to the CEQA Guidelines, the following significance criteria will be used:
There would be a significant cumulative contribution to global climate change if:
1. The project would generate GHG emissions, either directly or indirectly, that may
have a significant impact on the environment, or
2. The project would conflict with any applicable plan, policy or regulation of an
agency adopted for the purpose of reducing the emissions of GHGs.
Certain greenhouse gases defined by AB 32 would not be emitted by the project. Perfluorocarbons and
sulfur hexafluoride are typically used in industrial applications, none of which would be used by the
project. Therefore, it is not anticipated that the project would emit perfluorocarbons or sulfur
hexafluoride.
An inventory of greenhouse gas emissions generated by the project is presented below. The emissions
are converted to metric tons of carbon equivalents (MTCO,e) using the formula:
MTCO,e = (tons of gas) x (global warming potential) x (0.9072 metric tons of gas)
Temporary impacts would result from project construction activities. GHGs would be emitted by off -
road and on -road construction equipment and worker vehicles. Greenhouse gas emissions from motor
vehicles are assumed to remain the same over time because the emission factors used to estimate
emissions from the motor vehicles that would access the project site are currently calculated as remaining
constant. The on -road mobile inventory used the current version of the EMission FACtors model
(EMFAC2007), and the off -road mobile inventory used the OFFROAD model for base emission factors.
Both the EMFAC and OFFROAD Models develop carbon dioxide and methane emission estimates;
however, they are not currently used as the basis for ARB's official greenhouse gas inventory, which is
based on fuel usage information. It is important to note that the current versions of EMFAC and
OFFROAD are not fuel- based, but apply a single carbon dioxide factor that is unchanged throughout
future years. ARB is working to reconcile the emissions estimates from the fuel usage approach and the
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -31
models. Implementation of adopted regulations (sucli as AB 1493) and anticipated regulations will
reduce future motor vehicular emissions.
The project would emit greenhouse gases from upstream emission sources and direct sources
(combustion of fuels from worker vehicles and construction equipment). An upstream emission source
(also known as life cycle emissions) refers to emissions that were generated during the manufacture of
products to be used for construction of the project. Upstream emission sources for the project include
but are not limited to the following: emissions from the manufacture of cement; emissions from the
manufacture of steel; and /or emissions from the transportation of materials to the seller (i.e., URBEMIS
only estimates the transportation of building materials locally). The upstream emissions were not
estimated because they are not within the control of the project and to do so would be speculative at this
time. Therefore, pursuant to CEQA Guidelines Sections 15144 and 15145, upstream /life cycle
emissions are speculative and no further discussion is necessary.
Construction emissions were calculated by using URBEMIS (Urban Emissions — See Appendix A).
Although minimal demolition is required prior to construction, the existing reservoir may require full or
partial demolition after the new reservoir and pump station piping are placed in service. The decision
regarding the extent of the reservoir demolition work performed as part of the current construction
contract depends on funding availability. For purposes of this analysis, a worst -case scenario of full
demolition of the reservoir is assumed; refer to Table 3 below.

Linda Vista Tank and Pump Station Project — Draft In Stu /Mitigated Negative Declaration 432
Because impacts from construction activities occur over a relatively short -term time period, they
contribute a relatively small portion of the overall lifetime project GHG emissions. In addition, GHG
emission reduction measures for construction equipment are relatively limited. Therefore, in their Draft
Guidance Document — Interim CEQA Greenhouse Gas (GHG) Significance Thresholds, the SCAQMD
recommends that construction emissions be amortized over a 30 -year project lifetime so that GHG
reduction measures will address construction GHG emissions as part of the operational GHG reduction
strategies ( SCAQMD 2008a). To convert the CO, emissions data to CO,e, the CO, values are multiplied
by factors relating CH., and N,O emissions to CO emissions for diesel engines and then converted to the
metric equivalent. GHGs from project construction would be 24 MTCO,e as demonstrated in Table 3
above. Also, project construction will utilize recycled building materials where feasible and paints with
low VOCs (volatile organic compounds).
Operation
Operational or long -term emissions occur over the life of the project. There is no anticipated change in
operational emissions with implementation of the project. There is no change in electrical energy usage
for the first phase of the project. Energy usage for the future phase is unknown and depends on future
water demands and will be analyzed in future environmental documents should future site improvements
go forward.
No Impact. The proposed project is consistent with the applicable measures of the Scoping Plan and
the recommendations of the Attorney General. The SCAQMD is in the process of preparing
significance thresholds for greenhouse gases; however, the SCAQMD Board had not approved the
thresholds as of the preparation of this document. The current draft thresholds consist of a tiered
approach ( SCAQMD 2009). The SCAQMD adopted a threshold for industrial source projects, rules,
and plans when it is the lead agency for projects subject to CEQA ( SCAQMD 2008). The threshold
consists of five tiers. Tier 3 is a screening threshold level to determine significance using a 90 percent
emission capture rate approach and is 10,000 MTCO per year (with construction emissions amortized
over 30 years and added to operational emissions). The project would emit approximately 24 MTCO,e
per year amortized (or averaged) over 30 years. These emissions are under the SCAQMD's threshold for
industrial projects and the SCAQMD's draft thresholds.
One of the potential impacts of climate change is a decrease in the quantity and quality of water available.
One of the objectives of the project is to maintain the water supply for the surrounding area.
Construction of the project would emit minor quantities of greenhouse gases during construction, but
the project is necessary in order to help maintain the availability of water for the community.
Considering the above information, the project would result in no impact. The project is consistent with
any adopted applicable plan or policy to reduce GHGs and would not generate greenhouse gas
emissions, either directly or indirectly, that may have a significant impact on the environment.

The proposed project consists of the replacement of a water reservoir which obtains its water from four
existing wells, Well Nos. 42, 43, 44, and 52, located at the south and western borders of the adjacent
property, Anaheim Lake. A fifth well may be installed at the Anaheim Lake Property in the near future in
order to supply additional water to the reservoir. It is not a part this project's approval process, and a
separate environmental document will be prepared for the project should it go forward. The existing
onsite Sodium hypochlorite (NaOCI) system, a 12.5% solution similar to liquid bleach is used in the
disinfection process. An empty ammonia storage tank is on site, but presently not being utilized. The
tank could be used in the future, if the City were to decide to convert to a chloraminated disinfection
system; however, there are no plans at this time.
The EPA, at the Federal and State levels, determines whether a chemical, either in its liquid, gas, or solid
form could be a hazardous material. This determination is based on its potential to pose a hazard to
human health, safety, or the environment. A material may also be considered hazardous if it is listed on
any Federal, State, or Local Hazardous Materials List. Sodium hypochlorite is a nonflammable and
noncombustible material that is determined to be hazardous because of its corrosive properties that cause
mild irritation when in contact with the skin or eyes. It is added to the water pumped in from the 4 wells
on the adjacent Anaheim Lake property prior to its discharge to the reservoir. Because the Linda Vista
Reservoir site is also used as a storage facility for sodium hypochlorite for existing production wells in the
area, the storage system consists of two (2) 4,500 gallon bulk storage tanks housed within a CMU
building.
Transport of hazardous materials is regulated by the EPA and by the Department of Transportation
(DOT) under Title 49. The DOT requires vehicles that transport hazardous materials to be clearly
identified as such and drivers to be licensed to transport those types of materials. All transport will
comply with applicable Federal, State and local regulations.
Use and disposal of hazardous materials will be required to comply with Occupational Health and Safety
Administration (OSHA) regulations, EPA requirements, and Chapter 6.11, California Unified Hazardous
Waste and Hazardous Material Management Regulatory Program, of the Anaheim Municipal Code. The City of
Anaheim's Fire Department has been certified, in accordance with Health and Safety Code Sections
25404, et seq., as the Certified Unified Program Agency ( "CUPA ") for the City of Anaheim. The
reservoir has a project specific permit on file with the City of Anaheim and will update the required
Hazardous Materials Business Planllnventory to the Anaheim Fire Department for review and approval.

which will ensure compliance with all Regional Water Quality Control Board regulatory requirements.
Any discharges to the flood channel will also follow the requirements of the City's permit with Orange

The Preliminary Engineering Design Report that was prepared for this project (Psomas, August 2010; on

maintain the existing drainage pattern of sheet flow. No streams, rivers, or other water features are
present within the project's footprint. As part of project implementation, three swales would be installed
to capture runoff and return it to the groundwater system.
No Impact. All drainage for the proposed project site drains either via sheet flow or pipe flow to the
existing streets and storm drain system. Erosion or siltation could occur during construction- related
earthmoving activities, but the potential for erosion will be minimized by the implementation of typical
erosion control measures and standard practices. Once operational, runoff from the site is likely to be
reduced. Onsite storm drain facilities would be designed according to City of Anaheim standards to
accommodate anticipated peak storm flows. Three swales will be incorporated into the project to help
return water to the groundwater basin. Therefore, the potential for long -term (operational) site runoff
leading to off -site erosion or siltation will be reduced. Therefore, there would be no impacts in this
regard.

Installation of the new reservoir on Site 1 will require the removal of approximately 41,450 s.f. of
pervious surface. However, the existing reservoir on Site 2 will be demolished and partially filled
followed by installation of groundcover (hydro -seed) on the site which is approximately 65,900 s.f..
When the existing reservoir is demolished, there would be a net gain of 24,450 s.f. of pervious surface;
creating a favorable decrease in the overall drainage area. This change would not result in flooding on or
off -site. The front setback of Site 1 and 2 will be landscaped with groundcover and shrubs to help
capture surface runoff, thereby resulting in a less than significant impact. The project will not result in

removed, partially filled with soil from Site 2 and soil stockpiles from Anaheim Lake and then covered
with groundcover to create a pervious surface. However, this impact is minimal and with the installation

Installation of the new tank will result in the removal of approximately 41,450 s.f. of pervious surface in
order to allow for the construction of the new tank on Site 1. Demolition of the existing reservoir on
Site 2 will be filled with soil and would allow for the addition of 65, 900 s.f. of new pervious surface
resulting in a net gain of 24, 450 s.f. of pervious surface for the site. A landscaped perimeter, as well as
the installation of two natural swales will add to the capture of stormwater runoff at the site.
No Impact. Any new surface runoff would be offset through the infill via infiltration on Site 2
following removal of the existing reservoir which would create additional pervious surface. The addition
of 3 natural swales to the site will help increase stormwater capture and reduce runoff; therefore, there
would be no impacts to the site.

Seiche is the sloshing or wave of water that occurs within a closed or partially enclosed area of water such
as a lake, swimming pool, or reservoir from a few minutes to a few hours as a result of seismic activity,
such as an earthquake. According to the "Preliminary Design Report for the Linda Vista Reservoir"
(Psomas, July 2010), sloshing activity was analyzed using a sloshing height of 58 inches and CBC -07 and
ASCE 7 -05 standards. The analysis determined that 3' -6" inches would be the required freeboard for the
proposed covered reservoir in order to avoid any seiche -like impacts. Additionally, an outlet pipe will be
installed on the tank to drain any excess water into the adjacent OCFCD facility in case of an event such
as an earthquake- induced seiche.
The Geotechnical Report prepared by NMG Geotechnical, Inc. (Appendix G) indicates that "secondary
seismic hazards, such as a tsunami, are considered nil, as the site is located over 20 miles from the ocean
at an elevation of 238 msl.
The site is flat and there are no adjacent hillsides, therefore, there would be no impact from inundation
due to mudflow potential.
Less - Than - Significant Impact. There would be no impact from inundation from mudflow or a
tsunami as the sources that might cause these events do not occur within the project's vicinity. Although,
there is the potential for a seiche to occur within the reservoir following an event such as an earthquake,
inundation would not likely occur as the facility has been designed with this event in mind.

The Linda Vista Reservoir site is primarily surrounded by industrial and limited commercial land uses.
The proposed project is the construction of a 4 -MG tank, relocation of the existing 400 -zone and 555 -
zone pump station, new site piping and connections, and installation of an 8 -foot high block wall along
the eastern perimeter of Site 1. In order to operate more efficiently, the dual pump station will be
relocated to an area approximately 200 feet south of its existing location; in closer proximity to the new
tank.
Goal 1.1 of the Anaheim General Plan lists the following directive:
`Protect sensitive land uses from excessive noise through diligentplanning and regulation':
Some of the policies that are listed under this directive to meet this goal include: 1) considering the
compatibility of proposed land uses with the noise environmental when preparing, revising or reviewing
development proposals; 2) encouraging proper site planning and architecture to reduce noise impacts;
and, 3) requiring that site - specific noise studies be conducted by a qualified acoustic consultant utilizing
acceptable methodologies while reviewing while reviewing development that has the potential to impact
sensitive land uses.
Goal 3.1 of the General Plan states the following:
`Protect residents from the effects of ".spill over" or nuisance noise emanating from the City's activity centers"
Applicable polices under this directive include the following: 1) Prohibit new industrial uses from
exceeding commercial or residential stationary- source noise standards at the most proximate land uses, as
appropriate. (Industrial noise may spill over to proximate industrial uses so long as the combined noise
does not exceed the appropriate industrial standards.)
In order to make the above determination noise levels are determined to be excessive when sound levels
exceed established Federal, State, Regional, or local regulations. Sound pressure levels are used to
measure the intensity of sound and are described in terms of decibels. The decibel (dB) is a logarithmic
unit, which expresses the ratio of the sound pressure level being measured to a standard reference level.
A- weighted decibels (dBA) approximate the subjective response of the human ear to a broad frequency
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4-45
noise source by discriminating against very low and very high frequencies of the audible spectrum. They
are adjusted to reflect only those frequencies that are audible to the human ear.
Federal regulations typically apply to noise generated by transportation, e.g., highways, railways, aircraft,
etc. The Anaheim General Plan states that: "the major source of noise is from mobile sources and most
specifically, traffic traveling through the City on its various roadways and freeways. This is particularly
true for the City's industrial areas where traffic is characterized by heavy truck use. Another Federal
Agency, the EPA, has also set standards for exterior noise as they apply to residences. Since residential
land uses are located '/< mile north of the project site and north of the BNSF railway and Orangethorpe
Avenue, a major arterial road, measurements would not be pertinent to this noise analysis due to the
distance of the residences from the project site and the roadways that are characteristic of that area.
Sounds levels from the BNSF and Metrolink rail services, which are located approximately 235 feet south
of the residences, would reach close to 90 dBA and ultimately serve as the primary source point for noise
when compared to noise generated from the Linda Vista Reservoir site either during project operation or
construction. The Noise Information sheet that was prepared for this project (MBA, Appendix E)
indicates that for point sources located on hard ground surfaces such as asphalt, concrete, stone, or very
hard packed earth, a drop -off rate of 6.0 dBA /DD where "DD" is "doubling of the distance" would
apply. Ambient noise measurements taken adjacent to the residences, just south of Orangethorpe
Avenue, registered at 70.3 dBA (absent active rail activity) which exceeds the noise level of 61.3 dBA
generated by the existing Linda Vista Reservoir site. Additionally, the proposed project will relocate the
pump station approximately 200 feet south of its present location which will ultimately decrease
operational sound levels created by Linda Vista Reservoir upon those residences located north of
Orangethorpe Avenue.
Another Federal regulation, although not one that directly regulates noise, is responsible for the
protection of a potential sensitive receptor to loud noise; the Federal Migratory Bird Treaty Act. It is
responsible for the protection of migratory birds. This regulation prohibits the direct or indirect take of
any nest of a migratory bird during their nesting season. An indirect take can be caused by actions, such
as loud noise, that might disrupt the bird's nesting so that it would abandon its nest and leave behind any
unhatched eggs or young. As mentioned in Section 4.5 of this Checklist, there is a rookery or colony of
Great Blue Herons located on Site 1 (refer to Section 4.5, Biological Resources, of this Checklist for the
detailed analysis) where the new water tank is proposed to be constructed. This area is adjacent to a row
of Aleppo pines that has provided nesting habitat for the herons. The pines are located at the western
perimeter of the Linda Vista Reservoir and are adjacent to the recreational fishing lake, Anaheim Lake.
Fourteen Aleppo pine trees are present at the Linda Vista site; eight of which are located along the
western perimeter of Site 1. Two of the Aleppo contain nests the herons used during the last nesting
season that are still present in the trees. Project construction is scheduled to begin after July 31, 2011;
after the heron's breeding /nesting season, and continue until approximately December, 2012. Noise
from construction equipment has the potential to reach sound levels from 90 -100 dBA during the
shotcreting phase of tank construction which would occur in April; although this would not be
continuous at this noise level. In order to prevent any impacts during the nesting season, a mitigation
measure, temporary bird netting (refer to Mitigation Measure No. 1), will be applied in order to prevent
any impacts that construction noise could have upon nests, if they were to be active. Netting will be
removed once the nesting period is over or approximately in August of 2012. See Section 4.5, Biological
Resources, of this document for further information and mitigation measure content.
Linda Vista Tank and Pump Station Project— Draft Initial Study /Mitigated Negative Declaration 4 -46
According to OCWD's 2006 Draft Program EIR for the "Application to Appropriate Santa Ana River
Water ", great blue herons were observed at the Anaheim Lake site, the recharge basin /recreational
fishing lake located immediately west of the Linda Vista Reservoir site. The recharge basin has been
closed while the basin underwent routine dredging, but is scheduled to reopen in summer of 2011. There
is the possibility that this fish- stocked lake serves as a source of food for the heron whose primary diet is
fish. The southwest perimeter of Anaheim Lake is lined with Blue Gum Eucalyptus trees whose elevated
height could provide nesting habitat, whether permanent or temporary, for the heron.
State regulations. The California Office of Noise Control has identified Community Noise Exposure
Levels and their compatibility with land uses (refer to Appendix E). These regulations pertain to
permanent new development, rather than temporary noise impacts. The Office of Noise Control has
recommended that new utility type development projects that will produce sound levels in the range of
70 -80 dBA could acceptably go forward if a detailed analysis of noise impacts is made. Projects that emit
sound levels in the range of 75 -85 dBA would only be acceptable if project design included insulation
features. During project operation, the pump station will be the equipment generating the highest level
of sound; however at 66.6 dBA, it would meet the criteria for State noise regulations. Additionally, the
Linda Vista Reservoir is an unstaffed facility as the pump station is controlled automatically by SCADA
at an offsite location. Staff only visit the site to perform routine inspection and maintenance on the
facility.
Locally, the City of Anaheim regulates sound through the noise reduction policies of the Anaheim
General Plan and through Section 6.70 of the Anaheim Municipal Code. Section 6.70 states, "No person
shall, within the City, create any sound, radiated for extended periods from any premises which produces
a sound pressure level at any point on the property line in excess of 60 decibels." Noise from the project
would occur during construction activities and operation. Section 6.70 exempts construction noise
between the hours of 7:00 a.m. to 7:00 p.m. Noise that could occur during project operation was
analyzed through noise measurements using a precision sound level meter programmed in "slow" mode
and in "A" weighted form; consistent with the noise measurement requirements stated in Chapter 6.70 of
the Municipal Code. Noise measurements were taken from each property line of the premise on
Thursday, November 4, 2010 between the hours of 9:30 a.m. and 11:08 a.m. in order to document
existing baseline conditions at the Linda Vista Reservoir. The weather was clear, the temperature was 87
degrees, and humidity was 32 %. The number of pumps that were operating at the time of the noise
measurements is identified below. Anaheim Public Utility staff indicated that the number of pumps
operating at the time of the measurements is typical of the number of pumps operating at any one time."'
The pump station has 11 pumps, but not all operate simultaneously. The inspection process for the
City's other reservoirs could require all pumps to operate for a period of about 1 week every other year. "

vehicular traffic, noise levels ranged from 61.6 dBA (west property line) to 67.3 dBA (north property
line), and reached levels as high as 84.2 dBA when the BNSF line passed by during one set of the
readings. Sound measurements of the 400 -zone and 555 -zone pump stations recorded at 53.4 dBA; this is
the baseline noise level; without vehicle traffic in the vicinity. The existing ambient sound level recorded
at the east property line, near the proposed new location of the pump stations is 74.4 dBA; which
includes automobile/ truck traffic. Currently, a 6 -ft. high chain link is located on the north, south, west
property, and the majority of the east property lines for the site. The existing chain link fence that is
located on the eastern perimeter of Site 1 will be replaced with an 8 -ft. high CMU block wall as a result of
project construction. A row of trees will border the rear and front of the block wall for aesthetic
purposes. The Noise Information sheet that was prepared for this project (Appendix E) states that
"effective noise barriers can reduce noise levels by 10 to 15 dBA. A noise barrier or a wall will work best
if it is high enough and long enough to block the view of a road. A noise barrier is most effective when
placed close to the noise source or receiver." As a result of installation of the block wall, sound levels
could be further decreased. Future, additional phases of the project, if approved, consists of the
construction of a CMU building to enclose the pump station. Typical buildings could provide an exterior
to interior noise reduction of at least 30 dBA. "' This would result in a sound level of 39.8 — 50.4 dBA
for the pump station; well below the 60 dBA standard. However, should future phases not go forward
due to funding, etc., the project would still comply with the City's Noise Ordinance. Table 4 indicates
that existing Linda Vista Reservoir operations, excluding traffic from Tustin Avenue and absent a block
wall, currently meets the City's sound requirements of a maximum level of 60 dBA. The proposed
relocation of the pump station will not result in an increase in the number of pumps used, however the
number of pump cans will be increased in the event that further expansion of the pump station were to
go forward. Should that project go forward at some time in the future, any impacts would be addressed
in a separate environmental document.
Design features will be implemented as part of the project and included on the construction /grading
plans. This includes the following:
`All internal combustion engines on construction equipment shall be equipped with a muf$er of
a tppe recommended by the manufacturer. Nointemal combustion engine shall be operated on
the project site without said muffier. "
Less - Than - Significant Impact. Temporary noise impacts from project construction will occur,
however these impacts would be exempt under the City's Noise Ordinance. The noise impact analysis
that was conducted for this project indicates that noise impacts associated with the pump station during
operation of the project will not exceed the 60 dBA range requirement of Section 6.70. A future,
additional phase, if approved, would provide for a CMU building that would enclose the pump station
thereby, allowing sound levels to fall below existing sound levels.
The project site is surrounded by industrial and limited commercial land uses. Residential land uses are
located '/a mile north of the project site and north of a major arterial road, Orangethorpe Avenue, and
the BNSF /Metrohnk railway. An 8 -ft. high CMU block wall will be installed along the east boundary of
Site 1 as part of this phase of the project. The noise measurements that were taken as illustrated in Table
4 indicate that the greatest output of noise during operation of the project would not occur from the
reservoir but would originate from the automobile and truck traffic on Tustin and Orangethorpe
Avenues; and the rail activity stemming from the BNSF /Metrolink that is located north of Orangethorpe
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -50
Avenue. The noise levels from the 400 -zone and 555 -zone booster station pumps meet the code
requirement of a maximum dBA of 60 dBA at the property line (this is without measuring traffic noise
from nearby roads). All other State and local noise regulations would be met.
Federal regulations would be met, as well. However, compliance with the Federal regulation, the
Migratory Bird Treaty Act, will require the implementation of a mitigation measure in order to reduce
impacts to the great blue herons that utilize the Aleppo pine trees. In order to be able to meet the
construction schedule for the new reservoir, which serves as one of the primary sources of potable water
for the West Anaheim and the Hill and Canyon area, temporary discouragement measures in order to
discourage interruption of the project's construction schedule by potential nesting herons will be
followed.' These methods are designed to be temporary and noninvasive; examples include placing bird
netting in the Aleppo that currently have nests. This is designed to encourage the birds to nest in an
offsite location, at least until construction of the new tank and associated appurtenances have been
completed. Other sites within the area that could serve as temporary nesting sites in the area where great
blue herons have been previously observed are the adjacent Anaheim Lake, Warner Basin, and along the
Santa Ana River. The netting will be removed once construction activity is completed. It is worth noting
that construction activity at Linda Vista is not unfamiliar, as the site has undergone periodic site
improvements since 1962.

groundborne vibration or groundborne noise level?
Discussion
Groundborne noise or vibration is the periodic movement of mass over time. It is described in terms of
frequency and amplitude and is frequently detected while indoors since it is produced by noise radiating
from the motion of wall, windows, and /or floors of a building. Vibration can occur as a result of an
earthquake, machinery (such as construction equipment), heavy vehicles, trains, etc.
Unlike sound, there is no standard way of measuring and reporting amplitude as it is felt rather than
heard. Vibration is described in units of velocity (inches per second [in /sec]), and discussed in dB units in
order to compress the range of numbers required to describe vibration. The frequency of a vibrating
object describes how rapidly it is oscillating. The number of cycles per second of oscillation is the
vibration frequency, which is described in terms of hertz (Hz). The normal frequency range of most
groundborne vibration that can be felt generally starts from a low frequency of less than 1 Hz to a high
of about 200 Hz.
Construction activities will result in temporary and intermittent vibration impacts to the surrounding
area. Construction vibration is generally associated with pile driving and water blasting. Occasionally,
large bulldozers and loaded trucks can cause perceptible vibration levels at close proximity. Vibration -
sensitive receptors are generally considered to be humans who are engaged in activities or who are
utilizing land uses that may be subject to significant interference from vibration. Groundborne vibration
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -51
generated by construction projects is usually highest from pile drivers, soil compaction, jack - hammers,
and demolition- related activities. For this project, the primary sources of vibration would occur from
bulldozers and graders. Vibration impacts to structures may be estimated from the following equation,
which assumes point source vibration and normal propagation conditions:
PPV� = PPV. x (25/D)
In the equation, PPV is the peak particle velocity in in /sec of the equipment adjusted for distance;
PPV. is the reference vibration level in in /sec at 25 feet from the source, and D is the distance from the
equipment to the receiver. Particle velocity is the rate of speed at which soil particles move in inches per
second. Table 5 below includes typical vibration levels from construction activities.

Sensitive users would include nearby schools, churches, or residences. There are no schools or churches
in the vicinity and the nearest vibration- sensitive receptors would be the residences located '/a mile, or
approximately 1,320 feet north of the project site. The primary sources of vibration during construction
would be from bulldozers and graders. From Table 5 above, a large bulldozer would produce the largest
amount of equipment - related vibration on the project site: 0.089 inch per second PPV at 25 feet. It is
anticipated that the vibration levels caused by a large bulldozer operating on the edge of the area to be
disturbed during construction of the proposed project at the nearest structure (1,320 feet away) will be
less than 0.002 inch per second. Table 6 below describes human reaction and effect on buildings to

Daytime ambient noise surveys were conducted for the project on Thursday, November 4, 2010, to
document the existing noise environment at various locations in the study area. A total of twelve short-
term noise level measurements were collected and are shown in Table 4. The ambient, or existing, noise
environment in the project area is also influenced by traffic mainly on Tustin Avenue and Orangethorpe
Avenue and from the BSNF railroad located north of the project site. During the survey, average
daytime noise levels in the project area ranged from 62 dBA to 84 dBA.
Chain link fencing currently surrounds the project on the northern, western, and southern boundaries. A
surrounding land use that might be exposed to noise from the Linda Vista Reservoir site is the
wholesale /retail landscape shop Qohn Deere Landscape, Inc.) located south of Site 1. There is also a 2-
unit office building just west of John Deere Landscape, Inc.; presently vacant. A portion of the Anaheim
Lake /recharge basin is located north of Site 2 of the Linda Vista Reservoir. An auto auction dealer is
located east of the project on the east side of Tustin Avenue. Residential land uses are located 'A mile
north of the project site and north of Orangethorpe Avenue, a major arterial, and the BNSF, a freight
railway that is also shared by the Metrolink. The Metrolink together with the freight trains generate
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration 4 -53
approximately 75 trips per day along the BNSF. The Anaheim General Plan recognizes that "noise
generated along the rail lines can be substantially higher than in areas that are located away from the
tracks." Orangethorpe Avenue, a major arterial, is north of the project site. The Average Daily Traffic
count for this section of Orangethorpe Avenue is 10,000 - 20,000 trips per day (in both directions).
Based on this distance from the project site, and the type of road uses that separate the project site from
the residential uses located north or Orangethorpe Avenue, noise levels generated by the project would
not be expected to have any noise impacts upon the residential community. The land uses are consistent
with the industrial setting of the Anaheim Canyon Business Center and the Northeast Specific Plan
(SP94 -1).
Noise from the project's mechanical equipment would not be increased at this time. The existing chain
link fence on the eastern border of Site 1 will be replaced with an 8 -ft. high block wall and multi - layered
landscaping consisting of groundcover, shrubs and two rows of trees. Trees will also be added within the
first 50 feet of the side setback between Site 1 and John Deere Landscape, Inc. It is expected that the
addition of both the block wall and the new landscaping will decrease existing ambient noise levels for
existing land uses in the vicinity.
The relocation of the pump station to its proposed location of 200 feet southeast of its present location
will increase ambient noise levels adjacent to the great blue heron rookery located along the southwest
perimeter of the site. The existing ambient noise level measured when adjacent to the existing rookery
nesting site (with area traffic included) is an average of 61.6 dBA. According to the Noise Information
sheet that was prepared for this project (Appendix E), ambient noise levels will increase slightly to 68.5
dBA. There is not sufficient reference literature, at this time, to conclude what impacts this increase
would have upon the great blue heron rookery nesting site. In humans, a change of 5 dBA is discernable
to most people in an exterior environment, but whether the herons would share this same impact and
whether this impact would cause any change in behavior is unknown.
Fourteen Aleppo trees are located on the Linda Vista Reservoir site; eight of which are located in the
vicinity of the existing rookery. At the time of preparation of this document, two of the eight trees
contain empty nests from the previous nesting season. Staff has been in consultation with the U.S. Fish
& Wildlife and the California Department of Fish Game. The latter is a trustee agency and has listed the
rookery of the great blue heron on their "Special Animal" list. To avoid impacts to the heron,
construction on the project will not begin until after the heron nesting season or approximately July 31,
2011. As discussed previously, the Linda Vista Reservoir site is not unfamiliar to tenant improvements.
The site has undergone periodic improvements since 1962.
As previously discussed, a building will be constructed to enclose the pump station, as funds permit, but
potentially within five years. There is also the potential that the existing Aleppo trees located near the
existing pump station that are not currently used for nesting sites, could serve as a valid nesting site
following relocation of the pump station as the level of perceivable noise generated by the relocated
pump station will be below its existing level of 66.6 at 5 feet from the pump station. It is expected that
the slight increase in noise levels, 68.6 dBA compared to 61.6 dBA that could be perceived by the
rookery following relocation of the pump, will not create a significant impact.
Less- Than - Significant Impact. There will be a less than significant permanent increase in ambient
noise levels for existing surrounding land uses. The relocation of the existing pump station to an area
Linda Vista Tank and Pump Station Project — Draft Ini Study /Mitiga Negative Declaration 4 -54
that is closer to the existing nesting sites of the great blue herons will result in a negligible increase in
ambient noise levels. Additionally existing Aleppo trees that are currently not being used as nesting sites
will be trimmed to encourage growth and adequate branching for perches following relocation of the
pump station.
Development of the project will result in an increase in temporary noise impacts from construction of
the project. Construction equipment includes, but is not limited to bulldozers, graders, loaders, an
excavator, backhoe, etc. In typical construction projects, grading activities generate the highest noise
levels as grading involves the largest equipment. Noise levels measured at a distance of 50 feet from an
individual piece of typical construction equipment can reach 90 dBA L,,, Following completion of
construction of the proposed project which could take up to 16 months, the water reservoir tank will
undergo prestressing and shotcreting operations. These operations are expected to require approximately
25 working days, of which approximately seven days would consist of water blasting and seven days of
shotcreting. Noise levels during tank water blasting at other projects have measured noise levels up to 80
dB at 100 feet from the tank. The Anaheim Municipal Code, Chapter 6.70, exempts noise generated by
construction during the hours of 7 a.m. to 7 p.m., as these impacts would be temporary and during
daytime hours.
The Federal Migratory Bird Treaty Act prohibits the take of the nest of any migratory bird during the
bird nesting season; for the great blue heron this period is from February 1 through July 31. This would
result in the nearest noise sensitive receptor to the project site the rookery of the great blue herons
located along the southwest perimeter of the site. The Noise Information sheet (Appendix E) that was
prepared for this project indicates that the blue heron nesting areas would experience the greatest noise
impact, with a noise level of 100.0 dB during the prestressing and shotcreting procedure. To avoid any
impacts to potential nesting herons, project construction will begin in August 2011, following the nesting
season. As construction will occur over an estimated 16 -month period, the trees that are part of the
existing rookery will be applied with temporary bird netting in prior to the 2012 nesting season in order
to prevent birds from nesting in the trees during construction. If no netting were to be placed prior to
construction and nesting occurred, those nests would required, by the Migratory Bird Treaty Act, to have
a 300 -foot buffer to be placed around them prohibiting construction activity. As tank shotcreting
activities are scheduled to take place within 25 feet of the rookery, construction on this project would
have been unable to continue. The temporary bird netting is a noninvasive method to temporarily

discourage birds from nesting in the trees. The netting will be removed once shotcreting activities are
completed, or approximately August 2012.
Less - Than - Significant Impact. Construction activities would be heard in the project site vicinity
above the existing ambient noise levels. Noise increases would vary depending on the type of equipment,
power requirements, and location and would occur intermittently. The implementation of the proposed
project is expected to create temporary and intermittent short -term annoyance for the local receptors,
especially during site preparation (grading) and trenching, which would cease after the construction of the
project. However, noise sources associated with construction are exempt between the hours of 7:00 AM
to 7:00 PM per the City Noise Ordinance of the Anaheim Municipal Code (Chapter Section 6.70);
therefore, any impacts would be less than significant. Construction would occur outside of the 2011
nesting season and a temporary, noninvasive measure to discourage nesting, bird netting, will be applied
to trees within the rookery. Therefore, any impacts would be less than significant.

Operational Impacts
The proposed project is the replacement of an existing 4 MG water reservoir with a similar type of
facility with the distinction that the new reservoir will be designed to meet current CBC seismic
standards. During project operation, vehicular trips will be limited to daily periodic visits by maintenance
staff in order to provide brief maintenance duties at the facility. The reservoir is located on Tustin
Avenue between Orangethorpe and Miraloma Avenues. This section of Tustin Avenue currently has an
LOS of "C ". LOS is a key indicator of a particular road's ability to accommodate traffic based on traffic
congestion and is rated on a scale from A -F where Level F is an indicator of the highest level of
congestion. The Anaheim General Plan (May 2004) describes LOS C as the following:
Stable operation continues. Full signal cycling loading is still intermittent, but more frequent. Occasional drives may have
to wait through more than one red signal intersection, and backups may develop behind turning vehicles
The Congestion Management Program is a traffic management plan for the County of Orange adopted
by OCTA. It requires a minimum level of LOS E to be met at specific congestion management
intersections. The nearest congestion management program intersection is located in the City of
Placentia, north of the project site at Tustin Avenue and Orangethorpe Avenue. During project
operation, there would not be an increase in vehicular trips to the site as it is not an expansion of its
current operation, and therefore, the LOS C designation would remain and therefore, the project would
be in compliance with the applicable Congestion Management Program. Additionally, a traffic signal will
be added near the site on Tustin Avenue in 2014 following the completion of OCTA's Grade Separation
Project on Tustin Avenue in order to provide increased efficiency on Tustin Avenue for ingress and
egress from the Linda Vista Reservoir site and the auto auction facility (Manheim) located on the east
side of Tustin Avenue.
Construction Impacts
During construction of the proposed project, temporary impacts to the existing street system from
construction vehicles and passenger cars used by construction workers entering and exiting the project
site could result in short -term traffic impacts to the project vicinity. Most construction vehicles will be
arriving to the site from the southerly direction or freeway system via Tustin Avenue which the
Circulation Element of the Anaheim General Plan (May 2004) identifies as one of the City's major truck
routes. It states, "Truck routes not only allow truck traffic to flow efficiently, they also minimize the
possible exposure of people in sensitive areas, such as residential neighborhoods and schools, to safety
and mobility impacts involving trucks or high noise levels that can be generated by truck traffic.
Directing truck traffic to specially designated truck routes minimizes impacts that could occur on local
roadways." Construction during the Linda Vista Reservoir project is expected to generate approximately
30 -40 daily vehicle trips during the most intensive phase of construction.
Traffic impacts that might occur during project construction were also analyzed in terms of three
additional projects occurring in the project vicinity that are proposed to begin at approximately the same
time as the Linda Vista Reservoir Project or around or shortly after summer of 2011. They are the
OCTA Grade Separation Project, the OCWD Miraloma Recharge Basin Project, and the Tustin
Avenue /La Palma Avenue Roadway Improvement Project. When construction begins on the
Kraemer /Crowther leg of the Grade Separation Project, traffic will be diverted from Kraemer Boulevard
and Crowther Avenue through Miraloma Avenue and Tustin /Rose Avenue beginning in June of 2011
Linda Vista Tank and Pump Station Project — Draft In Study /Mitigated Negative Declaration 461
and will be in place until the end of 2013. According to the LOS Analysis provided in OCTA's
Transportation Management Plan (October 15, 2010) that was prepared for the Kraemer Boulevard
Grade Separation Project, construction related trips will result in an additional 250 -300 morning and
evening or AM and PM peak hour trips which will result in a configuration of LOS D for the
Tustin /Rose- Orangethorpe Avenues intersection. The Tustin - Miraloma Avenue intersection will
maintain its designation of LOS C even with this detour of traffic from Kraemer Boulevard. OCWD's
Miraloma Recharge Basin project which will be located on Miraloma Avenue between Miller Avenue and
Kraemer Boulevard, southwest of the Linda Vista Reservoir site is scheduled to begin in October of 2011.
This project is currently in the Notice of Preparation (NOP) of the EIR phase and therefore, only limited
data regarding construction traffic is available at this time. OCWD is working with the City of Anaheim
Transportation /Traffic Division in the preparation of their traffic analysis and appropriate traffic detour
plans will be developed in consideration of ongoing construction activities in the area. The Tustin
Avenue /La Palma Avenue Improvement project is located south of the Linda Vista project site and is
tentatively scheduled to begin in summer of 2011. This project will ultimately improve the intersection's
current configuration from LOS E during peak traffic hours to LOS D. During the improvement, two
lanes in each direction on Tustin Avenue will be kept open at all times in order to keep circulation in that
area flowing. It is estimated that the Linda Vista Reservoir and Pump Station Improvement project will
generate at most, 30 -40 trips per day during its most intensive traffic phase of construction which is the
concrete pours for the new tank. This number of traffic trips would be less than significant as Tustin
Avenue in this vicinity would maintain its LOS C level at Miraloma and Tustin Avenues and LOS D at
Tustin /Rose and Orangethorpe Avenues during the construction period.
Less- Than - Significant Impact. In the vicinity of the project site, Tustin Avenue between
Orangethorpe Avenue and Miraloma Avenue is currently in compliance with the LOS levels required by
the Congestion Management Program and consequently, the Circulation Element of the Anaheim
General Plan. Construction of the proposed project will not result in increased impacts as a result of
project operation due to the fact that the project is a replacement of existing facilities, and not an
expansion of use. The project will actually increase the safety of ingress and egress on Tustin Avenue
from the Linda Vista Reservoir site and the auto auction facility, Manheim, located on the east side of
Tustin Avenue with the addition of a signal light in 2014, following completion of OCTA's Grade
Separation Project. Construction impacts related to the addition of vehicular trips would be negligible as
they would be temporary and would not lead to an increase in LOS levels of the surrounding area.

The facility is an unstaffed public utility that receives only brief daily visits from one or two employees to
the site. Public transportation would not be needed. The Anaheim General Plan designates this section
of Tustin Avenue for truck use in this industrial area and is not designated for a bicycle roadway.
However, as a result of construction of the project, a sidewalk will be constructed in front of the site; the
west side of Tustin Avenue, in order to accommodate any pedestrian traffic.

No Impact. Due to the fact that the facility is unstaffed, the project would not conflict with adopted
policies or plans regarding public transit. This section of Tustin Avenue is less pedestrian oriented due to
the industrial nature of the vicinity. However, the project will result in the addition of a sidewalk along
Tustin Avenue in front of the project site. Therefore the project would not impact these programs.

The proposed project consists of the replacement of a potable water supply reservoir that meets current
CBC code and design standards. The site is served by 4 existing production wells located on OCWD's
Anaheim Lake property which is located immediately west of the Linda -Vista Reservoir site. An
additional production well may be installed to replace an inactive well on the Anaheim Lake property.
Should an additional well be installed, it will be constructed on the Anaheim Lake property and a separate
environmental assessment would be provided at that time.
Less - Than - Significant Impact. The project is the replacement of an existing water reservoir with the
same capacity of 4.0 MG. It will be supplied by 4 production wells located on the adjacent OCWD
property; therefore, the impact of this project would be less than significant.

The proposed project is the replacement of an existing facility that has no regular staff other than City
employees who visit the site for periodic, routine and emergency maintenance procedures. A moderate
amount of additional solid waste will be generated during the construction phase. Construction or
commercial generated waste often contains materials that are recyclable which indicates that the material
will be disposed of at the local transfer station in Anaheim where recyclables will be removed. The
remaining solid waste will then be transferred to the local commercial landfill which is the Olinda -Alpha
Landfill in the City of Brea which currently has sufficient capacity until the year 2021.
Less - Than - Significant Impact. The local landfill that would receive the additional solid waste
generated during construction of this project has sufficient solid waste capacity until the year 2021.
Operation of the Linda Vista Reservoir will not result in a significant increase in solid waste; therefore,
any impact would be less than significant.

The proposed project is the replacement of an existing, partially -buried concrete 4.0 MG water reservoir
that was originally constructed in 1935. The replacement tank will be a partially buried 4.0 MG water
concrete tank. The parcel that will contain the new tank is partially vacant, but its perimeter has been
disturbed throughout the years by the placement of various reservoir related facilities. The area for the
proposed tank will be excavated in order to accommodate the 5 -ft depth of the tank that will be buried
below ground. Any archaeological and /or paleontological resources that may have existed on the site
have likely been removed or destroyed. Nevertheless, a cultural resources and paleontological records
search was conducted and it was reported that no cultural or paleontological resources exist within the
footprint of the site, however, standard protocol will be followed where the contractor will be required to
stop construction activities and a licensed archeologist or paleontologist will be contacted to be present at
the site in the event that cultural or paleontological resources are encountered during construction. This
is a design feature that has been added to the grading and construction plans.
The surrounding environment of the Linda Vista Reservoir site is relatively flat with a gentle slope and
located in the Canyon Business District of the City of Anaheim. Industrial and limited commercial land
Linda Vista Tank and Pump Station Project — Draft Initial Study /Mitigated Negative Declaration ¢g$
uses primarily characterize the area. An OCWD recharge groundwater basin, Anaheim Lake, that is also
used for seasonal recreational fishing is located immediately west of the Linda Vista site. Wildlife at the
Linda Vista Reservoir site is limited to a rookery of great blue herons that have left nests in two of the
onsite Aleppo pine trees located along the site's western perimeter. Great blue herons are not listed as an
endangered, threatened, candidate, or a Species of Concern. The population of the great blue heron is
not limited at this time in California, but when herons are associated with a rookery or a colony, then the
rookery is listed by the California Department of Fish & Game as a Special Animal. When a species is
listed on the Special Animal list it essentially means that Fish & Game has concern regarding the habitat
of this species because sufficient information regarding their basis for choosing a particular location isn't
fully known and areas for habitat may be subject to elimination due to development. What is known at
the Linda Vista site is that it is adjacent to a fish - stocked lake, Anaheim Lake, and coupled with the
knowledge that fish is a primary component of the heron's diet, it seems that the adjacent lake provides a
source of food for this migratory bird. Literature indicates that the heron prefers to nest in trees of tall
height and in locations subject to minimal human disturbance.
Being a migratory bird, the great blue heron is protected under the Federal Migratory Bird Treaty Act
which prohibits the take of any bird, nest, or its young during the bird breeding /nesting season. For the
great blue heron, this nesting season runs from approximately February 1 through July 31. Construction
of the Linda Vista Reservoir will begin with excavation for the new tank on Site 1 and is scheduled to
begin after August of 2011. Should the herons have returned to the nests in the Aleppo pine trees in
February of 2011, construction will begin following their departure, or approximately in August of 2011.
Construction is scheduled for 16 months, however, and therefore, work on the site will run into the next
potential breeding /nesting season in 2012. Site disturbance stemming from construction and workers at
the site could create a temporary situation where the existing rookery is no longer viewed as feasible
nesting location. There is the possibility that during the off hours of construction, i.e., weekends, etc. that
the herons could return to their site. This would result in a halt to the project and a delay in the
completion of this critical source of potable water for the community of Anaheim. In order to mitigate
or temporarily discourage the herons from using the site during the construction phase, wildlife sensitive
measures were obtained as a result of the City's consultation with the Department of Fish & Game. Staff
concluded that the most effective measure will be the covering of Aleppo pine trees with a net during late
September of early October of 2011. The nets will be in place until construction is completed or
October 2012. This measure was seen as the most effective as it is invasive, temporary, and due to the
fact that the Anaheim Lake site or nearby Kraemer recharge basin with trees similar in height could
provide a site for their temporary relocation.
No other significant plant life or wildlife is within the footprint of the project site.
Less -Than Significant Impact with Mitigation Incorporated. The proposed project site will not
result in the degradation of the environment or impact the population of an endangered, threatened, or
candidate species. No significant plant life is onsite. Ornamental silk oaks and Mexican fan palms are
located sporadically on Site 1; no significant plant life is onsite. Aleppo pine trees, which are also
ornamental in nature, house a rookery of great blue herons. While this is not a species whose population
is declining, its rookery is listed of concern on the Department of Fish & Game's Special Animal list.
Mitigation measures are being implemented into the project in order to protect the heron's rookery and
therefore, any impact would be less than significant.
Linda Vista Tank and Pump Station Project - Draft Initial Study /Mitigated Negative Declaration 4 -69
Implementation of the proposed project would require earth moving and construction activities. The
records search conducted for this project indicates that there are no identified archeological or
paleontological resources within the footprint of the project site. If it is determined, during the
construction phase, that resources are, or may be, present on the project site, standard protocol will be
followed and construction will be halted and a licensed archeologist or paleontologist will be contacted to
be present at the project site. This is a design feature that has been added to the grading and
construction plans.
b)
Does the project have impacts that are individually limited,
but cumulatively considerable? ( "Cumulatively considerable"
means that the incremental effects of a project are
considerable when viewed in connection with the effects of
past projects, the effects of other current projects, and the
effects of probable future projects)?

The project is the replacement of an existing facility and not the expansion of the existing use; therefore,
there would be no new significant impacts that would cause a cumulative effect. Traffic that will be
generated during the construction phase is limited during the most intensive phase of construction to 30-
40 trips per day during peak hour traffic. Three other projects will be occurring in the project vicinity, at
approximately the same time that the Linda Vista Reservoir will be under construction, however, LOS
levels will remain in compliance with the Congestion Management Program. Therefore there would be
no significant cumulative impact in this regard.
Less- Than - Significant Impact. When viewed within the context of other activities that are occurring
in the area, the project's impacts on the local and regional environment are negligible. Therefore, the
project's cumulative impact is less than significant.

PROJECT: Linda Vista Water Storage Tank and Pump Station
Improvement Project
PROJECT LOCATION: 1411 N. Tustin Avenue, Anaheim, CA 92806
PROJECT DESCRIPTION: The Linda Vista 4.0 MG storage reservoir was
constructed in 1935 and has reached its design life. The proposed project will replace the
existing 4.0 MG reservoir with a new 4.0 MG partially- buried (6 feet below and 32.5 ft
above ground) pre- stressed concrete tank (148 -ft inside diameter) The new tank will be
located in the southern area of the Linda Vista Complex. The existing reservoir will be
demolished and completely removed. In addition to the reservoir and pump station
replacement, new water pipelines will be installed as well as block wall, fencing and other
general civil and electrical site work to support the new facilities. New landscaping and
irrigation will be added to the site with the removal of some existing ornamental
landscaping.
