5.15 Public Utilities
This section describes the public utilities that would serve Village 8 West and evaluates the potential for
impacts to water, wastewater, recycled water, and energy services due to implementation of the
project. Water services is addressed in subsection 5.15.1, including existing conditions, regulatory
framework, and impact analysis. Wastewater is addressed in subsection 5.15.2, solid waste in subsection
5.15.3, recycled water in subsection 5.15.4, and energy in subsection 5.15.5.
As stated in Section 2.3, Purpose and Legal Authority, the analysis of public utilities in this EIR tiers from
the 2013 GPA/GDPA SEIR (09-01). The 2013 GPA/GDPA SEIR and 2005 GPU EIR concluded that impacts
related to water and energy would be significant and unavoidable because there is no assurance that
water supply or energy will be available to adequately serve the projected increase in population
resulting from development under the GPA/GDPA. The 2013 GPA/GDPA SEIR and 2005 GPU EIR
concluded that impacts to wastewater would be less than significant because the City could withhold
discretionary approvals and subsequent building permits from development that would cause the City to
exceed its wastewater capacity. The 2013 GPA/GDPA SEIR and 2005 GPU EIR concluded that impacts
related to solid waste would be less than significant.
The portions of this analysis related to water and sewer service are also based on the Final Overview of
Sewer Service and the Final Overview of Water Service for Otay Ranch Village 8 West, both prepared by
Dexter Wilson Engineering, Inc in November 2010. The analyses in this section pertaining to Village 8
West update the applicable information in these previously certified EIRs, which are incorporated by
reference.
5.15.1 Water
The following discussion of water impacts is based on the 2005 Urban Watershed Management Plans
(UWMP) adopted by the OWD and other relevant agencies. A 2010 UWMP was subsequently approved
in 2011. The 2010 UWMP included the water demand for Village 8 West. However, this analysis is based
on the 2005 UWMP because it was the most recent resource available at the time that the Notice of
Preparation for this EIR was published (July 2010), and during preparation of the Final Overview of
Water Service and the WSAV, discussed below.
5.15.1.1 Existing Conditions
A. Regulatory Framework
1. State
a. Senate Bills 610 and 221
SB 610 requires public water agencies, parties, or purveyors that may supply water to certain proposed
development projects to prepare a water supply assessment for use by the planning agency in
compliance with CEQA. A water supply assessment is required for any project that is subject to the CEQA
Guidelines and proposes to construct 500 or more residential units or the equivalent. SB 221 requires
proof of a sufficient water supply, while placing the initial burden of proof on the public water system.
SB 221 requires a city, county, or local agency to include as a condition in any TM that includes a
subdivision a requirement that a sufficient water supply shall be available to serve the subdivision.

CV EIR 10-03; SCH No. 2010062093 Page 5.15-2
City of Chula Vista
November 2013
The availability of a sufficient water supply is based on written verification from a water supplier with
more than 3,000 service connections (prior to or as a result of serving a subdivision) which may provide
water to the project. "Sufficient water supply" is the total water supplies available during normal, single-
dry and multiple-dry water years within a 20-year projection that will meet the projected demand of a
proposed subdivision. Moreover, and likely as an attempt to arrest reliance on "paper water"
entitlements from the State Water Project (SWP), SB 221 further requires any verification of "projected"
water supplies to be based on entitlement contracts, capital outlay programs, and regulatory permits
and approvals regarding the right to and capability of delivering the projected supply. These statutes
basically require that the water supplies be sufficient and meet projected demand , but do not specify a
particular number of gallons that must be provided.
b. Urban Water Management Plan Act
In 1983, the California Legislature enacted the Urban Water Management Act (California Water Code
Sections 10610 through 10657). The Act requires that any urban water supplier that provides water for
municipal purposes, either directly or indirectly to more than 3,000 customers or supplies more than
3,000 acre-feet of water, prepare and annually update an UWMP at least once every five years.
The Act requires a description of specific water supply projects and implementation schedules to meet
projected demands over the planning horizon; a description of the opportunities for the development of
desalinated water; information on groundwater (where groundwater is identified as an existing or
planned water source); description of water quality over the planning horizon; and description of water
management tools that maximize local resources and minimize imported water supplies. Additionally,
the Act requires evaluation of the reliability of a water supply as part of a development plan. This
includes a water supply reliability assessment, a water shortage contingency plan, and development of a
plan in case of an interruption of water supplies.
The Metropolitan Water District (MWD), San Diego County Water Authority (SDCWA), and OWD all play
a role in supplying water to the proposed Village 8 West. All of these agencies have prepared and
updated UWMPs in accordance with this statutory requirement.
c. Memorandum of Understanding Regarding Urban Water Conservation in California
The OWD is signatory to the Memorandum of Understanding (MOU) Regarding Urban Water
Conservation in California, which created the California Urban Water Conservation Council in 1991 in an
effort to reduce California's long-term water demands. Water conservation programs are developed and
implemented on the premise that water conservation increases the water supply by reducing the
demand on available supply, which is vital to the optimal utilization of a region's water supply resources.
As one of the first signatories to the MOU Regarding Urban Water Conservation in California, OWD has
made BMP implementation for water conservation the cornerstone of its conservation programs and a
key element in its water resource management strategy. As a member of the SDCWA, OWD also
benefits from regional programs performed on behalf of its member agencies. The BMP programs
implemented by OWD and regional BMP programs implemented by the SDCWA that benefit all their
member agencies are addressed in the OWD 2005 UWMP.
As a signatory to the MOU Regarding Urban Water Conservation in California, OWD is required to
submit biannual reports that detail the implementation of current water conservation practices. The
OWD voluntarily agreed to implement the fourteen water conservation BMPs beginning in 1992. The
OWD submits its report to the California Urban Water Conservation Council every two years. The OWD

BMP reports for 2001 to 2004, as well as the BMP Coverage Report for 2003-04, are included in the
OWD 2005 UWMP.
2. Local
a. City of Chula Vista General Plan
The Chula Vista General Plan recognizes that, in order to ensure adequate water service, water supplies
and facilities need to be maintained and expanded as the city’s population grows. The Chula Vista
General Plan includes objectives and policies in the Public Facilities and Services Element that require
development to plan for careful use of natural and man-made resources and services, and maximize
opportunities for conservation while minimizing waste (Objective LUT 62); and increase efficiencies in
water use through use of alternative technologies (Objective PFS 2). Additionally, the Housing Element
includes Objective H 2 to promote efficient use of water through adopted standards and incentive-based
policies to conserve limited resources and reduce long-term operational costs of housing. Growth
Management Objective GM 1 and Policy GM 1.11 encourage withholding discretionary approvals and
subsequent building permits from projects demonstrated to be out of compliance with applicable
threshold standards for water service.
b. Chula Vista Landscape Water Conservation Ordinance
In response to the new State Water Conservation in Landscaping Act (AB 1881), which required cities
and counties to adopt landscape water conservation ordinances by January 1, 2010, the City of Chula
Vista adopted the Chula Vista Landscape Water Conservation Ordinance (Chapter 20.12 of the Municipal
Code). This ordinance calls for greater efforts at water conservation and more efficient use of water in
landscaping.
c. Otay Water District Growth Management Oversight Commission Questionnaire
Prepared by the OWD in support of the 2012 GMOC Annual Report, the GMOC Questionnaire responds
to the issue of whether existing water systems are able to serve projected growth for Chula Vista. The
questionnaire provided an opportunity for OWD to identify capital improvement programs required to
serve the forecasted water demands. The questionnaire identified a list of capital improvement projects
(CIPs) that would need to be implemented by the OWD in order to meet projected demand. The
questionnaire concluded that the near-term water supply outlook remains “unsettled,” while the city’s
long-term growth should be assured of a reliable water supply. The water supply is considered unsettled
because water supply agencies throughout California continue to face climatological, environmental,
legal, and other challenges that impact water source supply conditions. However, challenges such as
these are expected to always be present, and the OWD nevertheless fully intends to have sufficient,
reliable supplies to serve demands.
d. City of Chula Vista Growth Management Program
Chula Vista’s Growth Management Program’s goal for water supply is to ensure that adequate supplies
of quality water (appropriate for intended uses) are available to the City of Chula Vista. The Growth
Management Program has two objectives regarding water supply and distribution: 1) ensure that
adequate storage, treatment, and transmission facilities are constructed concurrently with planned
growth; and 2) ensure that water quality standards are not jeopardized during growth and construction.

City of Chula Vista
November 2013
The growth management threshold standard for water supply and distribution states:
1. The applicant will request and deliver to the City a service availability letter from the water
district for each project.
2. The City shall provide annually to the San Diego County Water Authority, the Sweetwater
Authority and the Otay Municipal Water District a 12- to 18-month development forecast and
request an evaluation of their ability to accommodate the forecast and continuing growth. The
districts’ replies should address the following:
a. Water availability to the city and planning area, considering both short and long term
perspectives;
b. Amount of current capacity, including storage capacity, now used or committed;
c. Ability of affected facilities to absorb forecast growth;
d. Evaluation of funding and site availability for projected new facilities; and
e. Other relevant information the district(s) desire(s) to communicate to the City and the
GMOC. The growth forecast and water district response letters shall be provided to the
GMOC for inclusion in its review.
The Chula Vista Growth Management Ordinance (CVMC Section 19.09.050C) requires a Water
Conservation Plan (WCP) to be submitted with all SPA Plans. In accordance with the Growth
Management Program, WCPs must provide an analysis of water usage requirements of the project.
B. Existing Water Services
1. Water Service Providers and Planning
Water service to Village 8 West would be provided by OWD. OWD purchases water from the SDCWA,
which in turn imports water from the MWD. The projected supply and demand and planning documents
for each of these agencies is described below.
a. Metropolitan Water District
MWD supplies water to approximately 19 million people in a 5,200-square mile service area that
includes portions of Ventura, Los Angeles, Orange, San Bernardino, Riverside, and San Diego counties.
SDCWA is one of MWD’s 27 member agencies. Supply and demand projection information for MWD is
included in its 2005 UWMP. MWD gets its water from two sources. The first source is the Colorado
River, which is connected to MWD’s six-county service area through the 242-mile Colorado River
Aqueduct. The second source is water from northern California, which supplies water through a series of
dams, aqueducts, pipelines, and other facilities known as the SWP. The SWP is operated by the
California Department of Water Resources.
Since 1996, MWD has operated under a 20-year resource plan designed to balance local and imported
supplies. The 1996 Integrated Water Resources Plan called for investments in water conservation,
recycling, groundwater treatment storage, and water transfers in order to diversify and stabilize MWD’s
water supplies. On November 8, 2005, the MWD adopted its 2005 Regional UWMP. In its 2005 UWMP,
MWD evaluated water supply reliability over a 20-year period, for average, single-dry and multiple-dry
water years. To complete its most recent water supply reliability assessment, MWD developed
estimates of total retail demands for the region, factoring in the impacts of conservation. MWD's
reliability assessment showed that MWD can maintain reliable water supplies to meet projected

demands through the year 2030. MWD also identified buffer supplies, including other SWP groundwater
storage and transfers, which could serve to supply additional water needs. Appendix A-3 to the MWD
2005 Regional UWMP contains detailed justifications for the sources of supply projected to meet water
demands in the region, including Colorado River Aqueduct deliveries (Colorado River supplies) and
California Aqueduct deliveries (SWP supplies).
Additionally, MWD has comprehensive plans for stages of actions it would undertake to address up to a
50 percent reduction in its water supplies and a catastrophic interruption in water supplies through its
Water Surplus and Drought Management and Water Supply Allocation Plans. MWD is working with the
state to implement a comprehensive improvement plan to address catastrophic occurrences that could
occur outside of the Southern California region, such as a maximum probable seismic event in the
Sacramento-San Joaquin Delta, a key water resource, which would cause levee failure and disruption of
SWP deliveries.
b. San Diego County Water Authority
The SDCWA service area covers approximately 922,000 acres and encompasses the western third of San
Diego County. SDCWA has 24 member agencies. The SDCWA is responsible for ensuring a safe and
reliable water supply to support the region and the quality of life for three million residents. Because of
the county’s semi-arid climate and limited local water supplies, SDCWA imports between 70 and 95
percent of the water used in the San Diego region from MWD. In 2008, MWD provided 71 percent of the
San Diego region's water supply. Historically, SDCWA has relied on imported water supplies purchased
from the MWD to meet the needs of its member agencies. SDCWA is the largest MWD member agency
in terms of deliveries, purchasing approximately 25 percent of MWD's water. SANDAG is responsible for
providing and updating land use planning and demographic forecasts for San Diego County. MWD and
SDCWA update their water demand and supply estimates based on the most recent SANDAG forecasts
approximately every five years to coincide with preparation of the their respective UWMPs.
The SDCWA 2005 UWMP reports that the San Diego region conserved an average of 40,500 acre feet
per year (AFY) over a five year period. In addition, in 2003, conserved agricultural transfer water from
the Imperial Valley began flowing to the San Diego region, which will provide 200,000 AFY by 2021. This
additional water supply is the result of SDCWA entering into the Quantification Settlement Agreement
with other water agencies in October 2003, including the SDCWA/Imperial Irrigation District (IID)
transfer agreement. Transfers from IID began in late 2003 with the signing of the settlement agreement.
The SDCWA will receive up to 200,000 AFY after an initial ramp-up in water deliveries. A summary of
projected imported water supply is provided in Table 5.15-1.

On November 17, 2005, the SDCWA adopted its 2005 UWMP. Sections 4 and 5 of SDCWA’s 2005 UWMP
contain documentation of SDCWA’s existing and planned water supplies, including MWD supplies,
SDCWA supplies, and local member agency supplies. SDCWA supplies include: 1) IID water transfer
supplies, 2) 77,770 AFY from conservation projects to line the All-American Canal and the Coachella
Canal, located in Imperial and Coachella Valleys, and 3) development of a seawater desalination facility
at the Encina Power Plant in Carlsbad, which is anticipated to produce 56,000 AFY of additional water
supplies. Additionally, since 1980, five percent to 30 percent of the water used by SDCWA member
agencies has come from local sources, primarily from surface water reservoirs. Recycled water and
groundwater recovery projects are growing in importance in the region, and water conservation efforts
have also made SDCWA member agencies less dependent on imported water. Projected local water
supply is summarized in Table 5.15-2.

City of Chula Vista
November 2013
SDCWA’s Board of Directors prepared the 2008 Strategic Plan and the 2008 Business Plan to provide
clear direction for the SDCWA to continue to increase the reliability of the water supply to meet the San
Diego region’s demands, and to ensure cost effective, environmentally sensitive, and safe delivery of
those supplies. Since its adoption, SDCWA has adopted policies and programs in the areas of supply
reliability, system infrastructure, finance, and outreach to help accomplish its mission to provide a safe
and reliable water supply to its member agencies serving the San Diego region. SDCWA’s long-term
commitment also involves diversifying the region’s water supplies portfolio, reducing the region’s
reliance on imported water, and optimizing facilities to provide the flexibility needed to respond to the
region’s ever-changing water needs.
To prepare the San Diego region for potential water shortages, in March 2008 the SDCWA released a
Model Drought Response Ordinance to its member agencies. The Model Drought Response Ordinance
has identified four drought response levels that contain water-use restrictions to help achieve demand
reduction during water shortages. Member agencies are using the SDCWA’s model to update their own
ordinances to help provide consistency throughout the region on response levels and water use
restrictions that may be taken to reduce water demand.
c. Otay Water District
Potable water would be supplied to Village 8 West by OWD, which currently relies on SDCWA for its
water supply. In San Diego County, OWD provides water services to southern El Cajon, La Mesa, Rancho
San Diego, Jamul, Spring Valley, Bonita, eastern Chula Vista, the Eastlake community, Otay Ranch, and
Otay Mesa along the U.S./Mexico international border. OWD covers 137 square miles and has
approximately 38,870 meter connections. OWD has approximately 450 miles of pipelines, 21 pump
stations, and 37 reservoirs with a total storage capacity of 190 million gallons. OWD provides 90 percent
of its water service to residential land uses, and 10 percent to commercial, industrial, and other land
uses. Average daily consumption for OWD is 40,324 acre feet. OWD maintains five major systems to
supply and deliver water, which include Hillsdale, Regulatory, La Presa, Central, and Otay Mesa. OWD
also operates the Ralph W. Chapman Water Recycling Facility.
On December 7, 2005, OWD’s Board of Directors adopted the OWD 2005 UWMP. Section 7 of the 2005
UWMP contains OWD’s water service reliability assessment. OWD is investigating the potential for
developing local groundwater to reduce its dependence on imported water. OWD’s UWMP identifies
sources of water other than imported water that are being evaluated, including local groundwater
supply, proposed regional seawater desalination project at the Encina Power Station, and recycled water
programs. OWD currently does not use local groundwater to meet any of its demands. OWD maintains
an active recycled water program and is actively pursuing conservation programs.
2. Water Supply Challenges
Since adoption of the 2005 UWMPs, multiple events occurred that affected southern California’s water
supply. The Colorado River has experienced drought conditions for eight of the last nine years.
Additionally, the SWP in northern California experienced three years (2006-2008) of drought conditions,
which substantially depleted storage in reservoirs throughout the SWP system, including San Diego
County. After a record dry spring that dramatically curtailed snow runoff from the Sierra Nevada
Mountains, Governor Schwarzenegger declared an official statewide drought on June 4, 2008. In March
2011, Governor Jerry Brown proclaimed an end to the statewide drought.
In addition to extreme drought conditions, in August 2007, a U.S. Dis trict Court decision was issued to
protect the endangered Delta smelt (fish). This federal court ruling set operational limits on pumping in
5.15 Public Utilities

the Sacramento-San Joaquin Bay Delta from December 2007 to June 2008 to protect the Delta smelt.
Since the SDCWA and its member agencies import water from MWD, their water supply was impacted
by this Court ruling. Additionally, climate change due to global warming also creates uncertainties that
may significantly affect California’s water resources over the long-term.
3. Existing Infrastructure
The project would be served by the Central Service Area of the OWD. This area of OWD is supplied
water from Connection Numbers 10 and 12 to the SDCWA aqueduct, which fills the reservoirs in the 624
Zone. Water is then distributed within the 624 Zone and pumped to the 711 Zone storage and
distribution system. The following paragraphs describe the existing potable water facilities located in the
vicinity of the project.
a. 624 Zone
The 624 Zone has three existing storage reservoirs. The 624-2 Reservoir is located adjacent to the
SDCWA aqueduct between Otay Lakes Road and East H Street, has a capacity of 8.0 million gallons and is
supplied by Connection Number 10 to the SDCWA aqueduct. The 624-1 and 624-3 Reservoirs are
supplied by Connection Number 12 and have a capacity of 12.4 million gallons and 30 million gallons,
respectively. The 624-1 reservoir is located adjacent to the eastern boundary of Otay Ranch Village 5
and the 624-3 reservoir is located along Eastlake Parkway, just north of the Olympic Parkway. In the
vicinity of Village 8 West, there are currently no 624 Zone facilities. Water will be supplied to the 624
Zone in this area by the 711 Zone system.
b. 711 Zone
There is currently one pump station in the 711 Zone, referred to as the Central Area Pump Station,
which is located at the 624-1 Reservoir site adjacent to the eastern boundary of Otay Ranch Village 5.
This station pumps water from the 624 Zone system into the 711 Zone distribution system and into two
existing 711 Zone reservoirs located in the Eastlake Greens development. The 711 Zone Pump Station
currently has five pumps (one standby), each rated for 4,000 gallons per minute (gpm) which results in a
firm station capacity of 16,000 gpm. There are three existing reservoirs in the 711 Zone. Two reservoirs
are located at the same site within the Eastlake Greens development and have capacities of 2.8 and 2.2
million gallons for a total of 5.0 million gallons. A 16.0 million gallon reservoir, 711-3, was constructed
north of the Rolling Hills Ranch project. With the construction of this reservoir, the OWD now has
enough storage within the 711 Zone to meet the demands from ultimate projected development in the
Central Area.
The major 711 Zone pipelines in the vicinity of Village 8 West include a 12-inch line in La Media Road and
a 12-inch line in Main Street.
5.15.1.2 Thresholds of Significance
According to Appendix G of the CEQA Guidelines, the project would result in a significant impact to
water services if it would:
■ Threshold 1: Require or result in the construction of new water treatment facilities or expansion
of existing facilities, the construction of which could cause significant environmental effects.
■ Threshold 2: Have insufficient water supplies available to serve the project from existing
entitlements and resources, or require new or expanded entitlements.

■ Threshold 3: Exceed city threshold standards which seek to ensure that adequate supplies of
quality water, appropriate for intended uses, are available. The standards require the applicant
must request and deliver to the city service availability letters from the appropriate water
district for each project; the applicant is required to submit a Water Conservation Plan along
with the SPA Plan application; and the project plans shall ensure an adequate supply of water on
a long-term basis prior to the development of each Otay Ranch SPA.
■ Threshold 4: Be inconsistent with General Plan, GDP or other relevant objectives and policies
regarding water supply thereby resulting in a significant physical impact.
5.15.1.3 Impact Analysis
A. Threshold 1: Require or result in the construction of new water treatment
facilities or expansion of existing facilities, the construction of which could
cause significant environmental effects.
Village 8 West would receive water service by expanding the existing 624 and 711 Zone water systems,
described above under Existing Infrastructure. Figure 3-9, Potable Water System, provides the
recommended on-site potable water facilities for the project. In general, the project will be phased and
must ensure that the OWD looping criteria is met during all phases of development. The proposed
phasing for the potable water facilities is provided in Figure 5.15-1. Final location, sizing, phasing, and
hydraulic modeling of the project water system will be presented in the final SAMP that is prepared for
the project and submitted to OWD. A brief description of the facilities that would be required to serve
Village 8 West, based on the SPA Plan and TM, is provided below.
1. 624 Zone
The southern and northwest portions of the project would be served by the 624 Zone. The OWD Master
Plan identifies a 624 Zone line that will be extended from Heritage Road to the west and a line f rom
Otay Valley Road to the east that will ultimately supply this area. These pipelines would be installed
during construction Otay Valley Road and the extension of Heritage Road. Development of Village 8
West would begin prior to installation of these OWD pipelines and temporary infrastructure would be
installed if necessary to supply water until the ultimate pipelines are constructed. Based on OWD
criteria, if more than 70 equivalent dwelling units would be constructed prior to connection of the OWD
projects to the 624 Zone system, the 711 Zone system to the north would be expanded through the
installation of temporary 711/624 Zone pressure reducing stations within Village 8 West as needed as
part of the project (Nielsen 2012).
2. 711 Zone
The OWD Master Plan identifies proposed 12-inch 711 Zone water lines that are planned to be routed
through Village 8 West from Main Street to the east and La Media Road to the north. The 711 Zone
would be looped on site and will provide service to the northeast corner of the project and to a portion
of development by the western boundary of the project. The 711 Zone would also temporarily supply
the 624 Zone on site via a pressure reducing station until the OWD completes two pipeline extensions in
the 624 Zone, described above.

3. Project Phasing
Village 8 West is anticipated to develop in five major phases. The order in which the facilities will
develop is not known at this time. At the time the SAMP is prepared for the project, more detailed
information on the project phasing will be presented. A description of the water facilities required to
serve each individual phases of the project is described below. Figure 3-18, Development Phases,
graphically shows the proposed phasing of the project.
a. Orange Phase
The Orange phase is mostly in the 711 Zone with a few lots in the 624 Zone. The 711 Zone development
would be served by connecting to the existing 12-inch line in La Media Road and extending 711 Zone
lines to the development area. The 624 Zone portion of the project would require a temporary 711/624
Zone pressure reducing station until the other phases of the SPA and associated infrastructure would be
completed.
b. Blue Phase
The Blue phase is located in the southwest portion of the project. This area is primarily within the 624
Zone and would be served by constructing the off-site 12-inch line in La Media Road and constructing
the temporary 711/624 Zone pressure reducing station until the other phases of the SPA and associated
infrastructure would be completed.
c. Purple Phase
The Purple phase is located in the southeast corner of the project. Development in this area is within the
624 Zone and requires looped connections to the 624 Zone east of the project. If the 624 Zone has not
been developed east of the project, the 711 Zone system to the north would be expanded and the
temporary 711/624 Zone pressure reducing stations would be required.
d. Yellow Phase
The Yellow phase is located in the north portion of the project. To provide water service to this area of
the project, 8-inch and 12-inch water lines would need to be constructed. These lines would include
extending a 12-inch 711 Zone line off site to the north to connect to the existing 12-inch line in La Media
Road. A temporary 711/624 Zone pressure reducing station would be required to supply the proposed
624 Zone development to be constructed during this phase.
e. Green Phase
The Green phase is located on the eastern side of the project site. This area of the project would be
served by connecting to the off-site 12-inch water line in La Media Road and existing 12-inch line at the
intersection of main street and Magdalena Avenue and extending a 12-inch 711 Zone line to the
development area. The southern portion of this phase is within the 624 Zone and would require a
temporary 711/624 Zone pressure reducing station if the 624 Zone system has not been developed east
of the project.
The proposed pipeline would be installed using conventional construction methods, either open trench
excavation or a boring and jacking method. Installation of on-site and off-site water lines have the
potential to generate vehicle and equipment emissions and dust, increase noise levels, impact
undiscovered cultural resources, and cause contamination of groundwater and erosion. These issues
have been addressed as part of the construction analyses presented in Sections 5.4 Air Quality,

5.6 Biological Resources, 5.7 Cultural Resources, 5.11 Hydrology and Water Quality, and 5.5 Noise of this
EIR. Mitigation measures are proposed in these sections to reduce construction impacts to a less than
significant level with the exception of air quality. Air pollutant emissions from installation of
infrastructure are included in the trenching phase of construction in Table 5.4-6, Maximum Daily
Emissions per Construction Activity. As shown in this table, all air pollutant emissions associated with
the installation of the underground utilities would be less than significant. Therefore, installation of the
water infrastructure required by buildout of Village 8 West would not result in significant environmental
effects and this impact would be less than significant.
B. Threshold 2: Have insufficient water supplies available to serve the project from
existing entitlements and resources, or require new or expanded entitlements.
Water service for the project would be provided by the OWD. Annexation into Improvement Districts 22
and 27 would be required prior to water service being provided. The OWD has existing and planned
facilities in the vicinity of the project and water service can be provided by expanding the existing
system, as detailed in the overview of water service (Appendix K2).
Water demand and required facilities for the project were determined based on the October 2008 OWD
Water Resources Master Plan. This document was amended in November 2010 to include the current
Village 8 West development plan. Table 5.15-6 presents the factors used in projecting the total average
day potable water demands. The required fire flows and durations are included in the total water
demand. The City of Chula Vista utilizes the California Fire Code for determining required fire flows and
durations for new development. The fire code utilizes a number of factors to determine the required fire
flow for a building. These factors include building footprint, building construction materials, and
whether or not the building has sprinklers. Since this level of detail is not known at the planning stage,
this report uses the fire flow requirements utilized by the OWD in master planning storage,
transmission, and distribution facilities throughout the OWD. The projected water demand for Village 8
West is summarized in Table 5.15-7. Additional details, such as the projected water demand for each
planning area, are available in the overview of water service (Appendix K2). As shown in Table 5.15-7,
the total estimated potable water use is approximately 0.79 mgd, or 881 acre feet per year.

The Village 8 West SPA Plan allows intensity transfer between planning areas provided that the overall
target intensity of 2,050 residential units and 300,000 square feet of non-residential floor area is not
exceeded. A request for an intensity transfer must be accompanied by a variety of findings, one of which
is that adequate infrastructure exists to support the transfer. This finding must be substantiated by an
updated technical study (in this case a water study) that ensures adequate infrastructure exists to
accommodate the transfer and that the target intensity is not exceeded. This provision in the SPA Plan
ensures that while water demand by planning area may shift, the total water demand for Village 8 West
would not exceed 786,575 gpd. A mitigation measure has been added to enforce this SPA provision.
As previously discussed, the OWD currently relies on the SDCWA for its water supply, which relies on the
MWD for 70 percent to 95 percent of its water supply. Therefore, the water supply overview relied on
the MWD, SDCWA, and OWD 2005 UWMPs, all of which are incorporated herein by reference, to ensure
that the project would have sufficient water supplies to meet demand for the project, in conjunction
with other planned and future development within the SDCWA service area.
In accordance with SB 610 and SB 221, OWD approved a WSAV in November 2010 for Village 8 West.
The WSAV includes, among other information, an identification of existing water supply entitlements,
water rights, water services contracts and agreements relevant to the identified water supply needs for
the proposed project. The WSAV evaluates water supplies that are or will be available during normal,
single-dry and multiple-dry water years during a 20-year projection to meet existing demands, expected
demands associated with the project, and reasonably foreseeable planned future water demands served
by OWD. The WSAV incorporates by reference the UWMPs and other water resources planning
documents of the OWD, SDCWA, and MWD. The WSAV determined that sufficient water supplies are
planned for and are intended to be available over a 20-year planning horizon, under normal conditions
and in single-dry and multiple-dry water years to meet the projected demand of Village 8 West and the
existing and other planned development projects to be served by the OWD.
Additionally, the Chula Vista Landscape Water Conservation Ordinance calls for greater water
conservation efforts and more efficient use of water in landscaping. The SPA Plan requires landscaping
to comply with this ordinance, and the requirements of the ordinance have been incorporated into the
WCP included in the SPA Plan. The project would promote water conservation through the use of low
water use plumbing fixtures and the use of recycled water for the irrigation of parks, open space slopes,
schools, parkway landscaping, and the common areas of multi-family residential and commercial sites.
Section 27.05 of the OWD Code of Ordinances also requires the implementation of water conservation
BMPs for new development, including installation of high efficiency water fixtures and appliances and
use of low water plants and smart irrigation controllers for landscaping. The OWD requirements have
been incorporated into the project WCP. The project is also required to contribute to the development
of alternative water supply projects through payment of the New Water Supply Fee adopted by the
OWD in May 2010. The potential water supply projects, such as the Rosarito Ocean Desalination Facility,
are in response to the regional water supply issues and are in various stages of the planning process.
Although the WSAV for the SPA Plan and the water supply and reliability studies from OWD identify
adequate water supplies for Village 8 West, the WSAV cannot ensure that water resources will be
available when needed. Conditions such as unanticipated drought conditions or delays in providing
planned infrastructure would potentially interfere with projected water supply. As stated in the 2005
GPU EIR and 2013 GPA/GDPA SEIR, because a long-term water supply is not assured, increases in water
demand would result in a significant impact. Therefore, because there is still no assurance of a long-
term supply of water in the future, the increase in water consumption associated with Village 8 West
would be significant.

C. Threshold 3: Exceed city threshold standard which seeks to ensure that
adequate supplies of quality water, appropriate for intended uses, are
available. The standard requires the applicant to request and deliver to the
city service availability letters from the appropriate water district for each
project; the applicant is required to submit a Water Conservation Plan along
with the SPA Plan application; and the project plans shall ensure an
adequate supply of water on a long-term basis prior to the development of
each Otay Ranch SPA.
The City of Chula Vista requires an applicant to provide service availability letters prior to issuance of a
building permit. Individual developers would be required to obtain service availability letters prior to
construction of land uses within Village 8 West. In addition, the SPA Plan includes a WCP to address
water use during project construction and operation. The WCP provides an analysis of water usage
requirements of the project, an overview of mandated water conservation measure, a detailed plan of
proposed measures for water conservation, use of recycled water, other means of reducing per capita
water consumption from the project, and a program to monitor compliance. The mandatory measures
identified in the WCP for residences are as follows:
1. Insulate hot water pipes with 1-inch walled pipe insulation, separate hot and cold water piping.
2. Set the maximum service pressure to 60 pounds per square inch to reduce any leakage present
and prevent excessive flow of water from all appliances and fixtures.
3. Install Water Efficient Dishwashers.
4. Install dual flush toilets within the project.
5. Comply with the Chula Vista Landscape Water Conservation Ordinance to reduce outdoor water
use. This will include selection of a more drought tolerant plant selection, including less turf area
as well as installation of water efficient irrigation systems.
The mandatory measures identified in the WCP for non-residential land uses are as follows:
1. Insulate hot water pipes with 1-inch walled pipe insulation.
2. Comply with Division 5.3 of the California Green Building Standards Code in effect at the time of
plan submittal.
3. Install pressure reducing valves.
4. Install dual flush toilets.
5. Install water efficient landscaping.
The project would also incorporate appliance efficiency regulations required by the state of California
(CCR Title 20). These include maximum flow rates for all new showerheads, lavatory faucets, sink
faucets, metering faucets in public restrooms, tub spout diverters, residential and commercial water
closets, and flushometer valves. Also, under the WCP, the project would use recycled water in all
common landscaped areas, in compliance with the recycled water requirements of the Chula Vista
Landscape Manual and OWD ordinance. The use of recycled water would not reduce the irrigation
demand for landscaping but would reduce potable water demand. The WCP is estimated to reduce total
water demand for the project by 202,505 gpd, which is a 22 percent reduction in estimated water use
compared to the usage without the incorporation of the conservation measures. As the project would
implement a WCP, it would be consistent with this threshold requirement.

Finally, as discussed above under Threshold 2, the WSAV prepared by the OWD describes current and
long-range storage capacity and ensures that the OWD would be able to absorb the forecasted growth
for Village 8 West. The WSAV also provided documentation of entitlements and contracts, and a
financial analysis of OWD’s maintenance and future water supplies. The WSAV report concludes that
adequate long-term water supply will be available to the project. The Overview of Water Service
prepared by Dexter Wilson Engineering also provides information that existing and OWD off-site
conveyance and storage facilities would be adequate to serve Village 8 West (see Appendix K2).
However, future individual developers within Village 8 West would be required to obtain service
availability letters and submit SAMPs for OWD approval in order to ensure that the project is consistent
with the city GMO thresholds. Therefore, this impact is potentially significant.
D. Threshold 4: Be inconsistent with General Plan, GDP, or other relevant
objectives and policies regarding water supply thereby resulting in a
significant physical impact.
Table 5.15-8 evaluates the consistency of the project with the applicable General Plan objectives and
Table 5.15-9 evaluates the project’s consistency with applicable GDP goals and objectives. As shown in
these tables, the project would be consistent with applicable water supply policies.
Table 5.15-8 Project Consistency with Applicable General Plan Water Service Policies
Applicable Policies Evaluation of Consistency
Objective LUT 62: Require development to consider and plan
for careful use of natural and man-made resources and
services, and maximize opportunities for conservation while
minimizing waste.
Policy LUT 62.1: Require developments within the East
Planning Area to provide resource management plans for
water, air quality, recycling, solid waste management, and
energy.
Consistent. The project is consistent with this General Plan
objective and Policy 62.1 because the SPA Plan includes a
WCP. The WCP addresses state, federal, and local water
conservation requirements as well as on-site water
conservation measures and estimated savings.
Objective PFS 2: Increase efficiencies in water use, wastewater
generation and its re-use, and handling of storm water runoff
throughout the city through use of alternative technologies.
Policy PFS 2.3: In designing water, wastewater, and drainage
facilities, limit the disruption of natural landforms and water
bodies. Encourage the use of natural channels that simulate
natural drainage ways while protecting property.
Consistent. The project is consistent with this objective and
Policy PFS 2.3. The proposed water distribution facilities would
be placed underground. No new water storage facilities are
required for the project.
Objective E 3: Minimize the impacts of growth and
development on water supply resources through the efficient
use and conservation of water by residents, businesses, and
city government.
Policy E 3.2: Promote the use of low water demand
landscaping and drought tolerant plant materials in both
existing and new development.
Consistent. The project would be consistent with General Plan
Policy E 3.2. The SPA Plan includes a WCP to promote water
conservation.
Objective H 2: Promote efficient use of water and energy
through adopted standards and incentive-based policies to
conserve limited resources and reduce long-term operational
costs of housing.
Policy H 2.1: Encourage the efficient use and conservation of
water by residents.
Consistent. See the analysis for Objective E 3.

Objective GM 1: Concurrent public facilities and services.
Policy GM 1.1: Maintain a set of quantitative levels of service
measures (Growth Management Threshold Standards) as a
tool to assess the relative impact of new facility and service
demands created by growth and apply those standards as
appropriate to approval of discretionary projects.
Consistent. The GMO contains a threshold standard to ensure
that the supply of water for existing and future residents is
available at a level and quality necessary for its intended use.
As discussed above, a WSAV has been prepared for the
project. The WSAV ensures that adequate water would be
available to serve the project. Should conditions change, this
General Plan objective includes policies that require detailed
forecasting of water demands, updating of threshold
standards, and monitoring of development activities to impose
limits on the rate of development to ensure water is available
commensurate with need. Therefore, the project would be
consistent with this objective.
Objective GM 3: Create and preserve vital neighborhoods.
Policy GM 3.3: Assure that all new and infill development
within existing urban areas pays its proportional share of the
cost for urban infrastructure and public facilities required to
maintain the Threshold Standards, as adopted for its area of
impact.
Consistent. See analysis for Objective GM 1.

Part II, Chapter 5 – Capital Facilities, Section C –Public Facility Plans
Goal: Ensure an adequate supply of water for build-out of the
entire Otay Ranch project area; design the Otay Ranch project
area to maximize water conservation.
Objective: Ensure an adequate supply of water on a long-term
basis prior to the development of each phase of the Otay
Ranch project area.
Objective: Ensure infrastructure is constructed concurrently
with planned growth, including adequate storage, treatment,
and transmission facilities, which are consistent with
development phasing goals, objectives and policies, and the
Service/Revenue Plan.
Consistent. The project is consistent with this objective
because it demonstrates that adequate water supply is
available. The project would implement a WCP to reduce
water use and help ensure long-term water supply.
Implementation of mitigation measure 5.15.1-1 would ensure
that water service is available to serve development prior to
construction. The SPA Plan includes a Water Infrastructure
Plan, provided in Appendix K2, which identifies the
infrastructure required for each phase of development, and
the project as a whole.
Objective: Promote water conservation through increased
efficiency in essential uses and use of low water demand
landscaping.
Consistent. Landscaping on the project site would be required
to comply with the City’s Landscape Water Conservation
Ordinance (CVMC §20.12). Additionally, the site would utilize
recycled water to reduce potable water use for landscaping.
Goal: Conserve water during and after construction of Otay
Ranch.
Objective: Reduce CWA water use within Otay Ranch to a level
that is 75% of County-wide, 1989 per capita levels.
Objective: Create a comprehensive framework for the design
implementation and maintenance of water conserving
measures, both indoor and outdoor.
Objective: Comply with the water conservation standards and
policies of all applicable jurisdictions.
Consistent. Development on the project site would be
required to adhere to the provisions of the WCP included in
the SPA Plan. Development would also be required to comply
with all city regulations related to water conservation, such as
the City’s Landscape Water Conservation Ordinance

A. New Water Treatment Facilities
No significant impacts related to new water treatment facilities have been identified for implementation
of the SPA Plan and TM.
B. Long-Term Water Supply and Entitlements
Long-term water supply availability cannot be guaranteed; therefore, the increase in water demand that
would result from implementation of the project would be potentially significant. Additionally, the
transfer of density between planning areas could have a significant impact to on-site infrastructure.
C. Compliance with City Water Supply Thresholds
Until future developers provide service availability letters and get approved SAMPs from OWD, the
project would not be in compliance with the city threshold standards.
D. Consistency with Water Supply Policies
No significant impacts related to consistency with water supply policies have been identified for
implementation of the SPA Plan and TM.
5.15.1.5 Mitigation Measures
A. New Water Treatment Facilities
No mitigation measures are required.
B. Long-Term Water Supply and Entitlements
The WSAV verifies that the OWD has adequate water supply for the project. Additionally, the project
would comply with the Chula Vista Landscape Water Conservation Ordinance, implement a WCP, and
utilize recycled water to reduce water demand. However, no mitigation measures are available to
guarantee a long-term water supply would be available to serve the project. The following mitigation
measure reduces impacts related to density transfers.

Intensity Transfer provision in the Village 8 West SPA, the applicant shall provide an update
to the Overview of Water Service for Otay Ranch Village 8 West (Dexter Wilson Engineering,
Inc. 2010) with each proposed project requesting an intensity transfer. The technical study
shall demonstrate to the satisfaction of the City Engineer that adequate on-site water
infrastructure will be available to support the transfer. The transfer of residential density
shall be limited by the ability of the on-site water supply infrastructure to accommodate
flows.
C. Compliance with City Water Supply Thresholds
5.15.1-2 Service Availability Letters. Prior to approval of each final map, the applicant shall request
and obtain a service availability letter from the Otay Water District and submit the letter to
the City of Chula Vista.

D. Consistency with Water Supply Policies
No mitigation measures are required.
5.15.1.6 Level of Significance After Mitigation
A. New Water Treatment Facilities
Impacts would be less than significant without mitigation.
B. Long-Term Water Supply and Entitlements
Mitigation measure 5.15.1-1 would reduce impacts related to density transfers to a less than significant
level. No mitigation measures are available to guarantee a long-term water supply would be available to
serve the project. As such, any increase in water demand would be considered significant. Therefore,
impacts would be significant and unavoidable.
C. Compliance with City Water Supply Thresholds
With implementation of mitigation measures 5.15.1-2 through 5.15.1-4 identified above, impacts
related to compliance with city thresholds would be mitigated to less than significant.
D. Consistency with Water Supply Policies
Impacts would be less than significant without mitigation.

5.15.2.1 Existing Conditions
A. Regulatory Framework
1. Local
a. City of Chula Vista General Plan
The Chula Vista General Plan recognizes that to ensure adequate and reliable sewer service and
facilities, services need to be maintained and expanded as the city population grows. The Chula Vista
General Plan includes objectives and policies in the Public Facilities and Services Element that increase
efficiencies in wastewater generation and its reuse through use of alternative technologies (Objective
PFS 2). Additionally, Growth Management Objective GM 1, and Policy GM 1.11 encourage withholding
discretionary approvals and subsequent building permits from projects demonstrated to be out of
compliance with applicable threshold standards for wastewater service.
b. Wastewater Master Plan
The Chula Vista Wastewater Master Plan was adopted in May 2005 for the purpose of evaluating the
capacity of the sewerage system, assessing the condition of existing pump station facilities, developing a
CIP for rehabilitation and expansion of the collection system, and recommendation of a revised capacity
charge. The 20-year CIP includes the recommended system improvements to address existing and
projected demand at build out. Future city flow estimates, based on 2005 growth projections, indicate
that the city would exceed its existing (or increased to 20.870 mgd) share in the City of San Diego
Metropolitan Wastewater Department Sewerage System (Metro system) by 2010. As such, the
wastewater generation analysis presented in the Wastewater Master Plan is intended to be used by the
city to establish a basis for future sewage capacity acquisitions to allow for the implementation of the
Chula Vista General Plan, as adopted in 2005. The city’s sewage capacity was not exceeded in 2010, and
the 2012 GMOC Annual Report concluded the city would not exceed its sewage capacity in the next five
years.
The Wastewater Master Plan also presents the methodology and findings of the sewer capacity
evaluation, including summaries of hydraulic computer model analyses used to present findings of
existing pump station assessments and recommended facility improvements. Sewer system design
standards under the Wastewater Master Plan are based on the Chula Vista Subdivision Manual Section
3-300. Recommended wastewater unit generation rates for use in design of sewer improvements are
shown in Table 5.15-10.

c. Chula Vista Municipal Code Growth Ordinance
CVMC Section 19.80.030 (Controlled Residential Development) is intended to ensure that new
development would not degrade existing public services and facilities below acceptable standards for
sewer and other public services. The preparation of the PFFP is required in conjunction with the SPA
Plan to ensure that the development of the project is consistent with the overall goals and policies of
the General Plan and would not degrade public services. Similarly, CVMC Section 19.09 (Growth
Management) provides policies and programs that tie the pace of development to the provision of
public facilities and improvements. Section 19.09.040G specifically requires that “that sewage flows and
volumes shall not exceed City engineering standards as set forth in the subdivision manual.” In addition,
the City must annually provide the San Diego Metropolitan Sewer Authority with a 12- to 18-month
development forecast and request confirmation that the projection is within the city’s purchased
capacity rights and an evaluation of their ability to accommodate the forecast and continuing growth, or
the City Engineering Department staff shall gather the necessary data. The information provided to the
GMO must include the following:
■ Amount of current capacity now used or committed;
■ Ability of affected facilities to absorb forecast growth;
■ Evaluation of funding and site availability for projected new facilities;
■ Other relevant information.
The development (growth) forecast and authority response letters are to be provided to the GMOC for
inclusion in its review. Section 19.09 also requires a PFFP and the demonstration that utilities, such as
sewer services, meet the GMOC quality of life threshold standards. The analysis of sewer services
provided in this section, along with the PFFP are intended to ensure funding for any needed expansion
of sewers and to confirm that wastewater services will be provided commensurate with development
and demand.
d. City of Chula Vista Municipal Code, Ordinance 2974
To reimburse the City for the cost to construct the Salt Creek Interceptor, all developments that propose
connections to this line are required to pay a development impact fee. Ordinance 2974 provides that the
fees are to be collected by the City for properties to be served by the Salt Creek Interceptor.
B. Existing Sewer Service
The City of Chula Vista operates and maintains it own sanitary collection system that connects to the
Metro sewerage system for treatment and disposal. The Metro sewerage system treats wastewater
from the city of San Diego and 15 other cities and districts, including Chula Vista. The San Diego
Metropolitan Sewer Authority regulates the three wastewater treatment plants: 1) the Point Loma
Wastewater Treatment Plant, 2) the Southbay Water Reclamation Plant, and 3) the North City Water
Reclamation Plant. Currently, the three combined treatment plants have a maximum permitted
treatment capacity of 285 mgd of wastewater for the City of San Diego and 15 other participating
agencies. All wastewater within the Otay Ranch area will eventually be conveyed to the Salt Creek Sewer
Interceptor that discharges into the Metro system. The wastewater would ultimately be treated by the
City of San Diego at the Point Loma Wastewater Treatment Plant. The Point Loma Wastewater
Treatment Plant currently treats approximately 180 million gallons of wastewater each day for the City
of San Diego and 15 other cities and districts in the region, and has a maximum daily treatment capacity
of 240 million gallons.

Chula Vista has wastewater treatment capacity rights to 20.864 mgd in the Metro system. According to
GMOC's 2012 Annual Report, Chula Vista generated an average flow of 16.219 mgd in fiscal year 2010;
therefore, it has remaining capacity of approximately 4.645 mgd. According to the Chula Vista
Wastewater Master Plan, Chula Vista would require 5.358 mgd of additional capacity to accommodate
City growth as projected in 2005. However, growth projections have been revised since the master plan
was prepared. The 2005 General Plan was adopted after preparation of the master plan, and
amendments have been adopted since 2005 to accommodate increased development capacities in
some areas, including Otay Ranch. The General Plan was recently amended to accommodate an
additional 494 homes in Village 8 West compared to 2005 General Plan projections.
The Salt Creek Interceptor Technical Sewer Study for the South Otay Ranch, prepared by Atkins
(formerly PBS&J) in November 2010, specifically looked at the impact of the updates to the General Plan
growth projection since approval of the 2005 General Plan, including Village 8 West. The Salt Creek
Interceptor Technical Sewer Study determined the City would need to acquire an additional 11.684 mgd
of capacity above current capacity rights. The City may acquire rights for this additional capacity in the
Metro system through negotiations with the City of San Diego, but the City of Chula Vista is also
evaluating the construction of a new wastewater treatment plant to meet its future treatment capacity
and disposal requirements. The project will be timed to proceed with the City’s acquisition of additional
treatment capacity. Building permits will be issued only if the City Engineer had determined that
adequate sewer capacity exists.
Village 8 West is located within the Salt Creek sewer basin. The Salt Creek Interceptor was planned,
designed, and constructed to convey projected development sewer flows in the eastern portions of
Chula Vista and unincorporated areas in San Diego County. At the location where the Salt Creek
Interceptor passes south of Village 8 West the line is 36 inches in diameter. There are no existing sewer
facilities within Village 8 West but facilities exist in Village 2 and Village 7.
5.15.2.2 Thresholds of Significance
According to Appendix G of the CEQA Guidelines, the project would result in a significant impact to
wastewater services if it would:
■ Threshold 1: Result in a determination by the wastewater treatment provider, which serves or
may serve the project, that it has inadequate capacity to serve the project’s projected demand
in addition to the providers existing commitments.
■ Threshold 2: Require the construction of new wastewater treatment facilities or expansion of
existing facilities, the construction of would cause significant environmental effects.
■ Threshold 3: Generate sewage flows and volumes that exceed City Engineering Standards as set
forth in the Subdivision Manual.
■ Threshold 4: Be inconsistent with the General Plan, GDP or other relevant objectives and
policies regarding wastewater thereby resulting in a significant physical impact.

5.15.2.3 Impact Analysis
A. Threshold 1: Result in a determination by the wastewater treatment provider
which serves or may serve the project that it has inadequate capacity to
serve the project’s projected demand in addition to the providers existing
commitments.
Sewer service for the project will be provided by the City of Chula Vista. Village 8 West is within the Salt
Creek sewer basin. The Salt Creek Interceptor was constructed to serve regional development in the
Otay Ranch area, and is located approximately 1,500 feet south of the project site.
The design criteria used to determine wastewater flow is based on the 2002 Chula Vista Subdivision
Manual sewer generation factors. The details of these factors are provided in Appendix L. The project’s
sewer generation according to proposed land uses is shown in Table 5.15-11. As shown in Table 5.15-11,
the projected average sewer flow for the project is 0.55 mgd. The estimated peak sewage flow is 1.07
mgd, which is equal to 2,074.4 equivalent dwelling units. Converting the proposed land uses to
equivalent dwelling units create a standard growth projection for utility demand that can easily be
compared to growth projections for Village 8 West in other documents.

The Village 8 West SPA allows intensity transfer between planning areas provided that the overall target
intensity of 2,050 residential units and 300,000 square feet of non-residential floor area is not exceeded.
A request for an intensity transfer must be accompanied by a variety of findings, one of which is that
adequate infrastructure exists to support the transfer. This finding must be substantiated by updated
technical studies, in this case a sewer study, which ensure adequate infrastructure exists to
accommodate the transfer and that the target intensity is not exceeded. This provision in the SPA Plan
ensures that while sewerage generation by planning area may shift, the total sewerage generation for
Village 8 West would not exceed 549,700 gpd. A mitigation measure has been added to enforce this
provision.
Chula Vista has wastewater treatment capacity rights of 20.864 mgd in the Metro system. According to
the GMOC 2012 Annual Report, Chula Vista generated an average flow of approximately 16.219 mgd,
and has a remaining capacity of approximately 4.645 mgd in the Metro system. Therefore, Chula Vista
currently has adequate capacity to serve the project’s direct impact on wastewater demand. However,
like other properties in the area, the proposed intensity of development in the SPA Plan has increased
from what was accounted for in the Wastewater Master Plan projections and would contribute to a
regional increase in wastewater generation. According to the November 2010 Salt Creek Interceptor

Technical Sewer Study, the City would need to acquire an additional 11.684 mgd of capacity above
current capacity rights to serve the estimated buildout of the city by 2030 under the current General
Plan, including implementation of the project.
Development of Village 8 West would require 0.55 mgd of treatment capacity. The increase of 0.55 mgd
is the portion of the city’s estimated 11.684 mgd capacity requirement that is attributable to Village 8
West. With a limited amount of treatment capacity remaining, the City is working on a variety of
alternatives that would provide additional treatment capacity in order to serve all of the anticipated
development within city limits. Building permits will be issued only if the City Engineer had determined
that adequate sewer capacity exists.
The Salt Creek Interceptor Technical Sewer Study also concluded that certain sections of the Salt Creek
Interceptor may require upgrades at ultimate buildout. However, these sections are upstream of the
project site and the study determined that the projected development of Village 8 West would not
exceed the capacity of the Salt Creek Interceptor or trigger the need for any upgrades. The total
equivalent dwelling units proposed for the project in the SPA Plan and TM (2,074.4 equivalent dwelling
units) is less than what was estimated in the Salt Creek Interceptor Technical Study (2,242.8 equivalent
dwelling units). Therefore, the development proposed in the project would not exceed the capacity of
the Salt Creek Interceptor.
The approximately 549,700 gpd generated by the project is within the city’s remaining capacity of 4.664
mgd. However, the project would be phased over a period of up to 20 years. The city’s sewer system
would potentially reach capacity during this time. If adequate sewer facilities are not provided
concurrently with demand, a significant impact would occur.
B. Threshold 2: Require the construction of new wastewater treatment facilities or
expansion of existing facilities, the construction of would cause significant
environmental effects.
Installation of new on-site and off-site wastewater conveyance lines that would contribute to or expand
existing facilities would be required as part of development of Village 8 West. The on-site sewer system
would consist of 8- to 15-inch diameter pipes, depending on the projected flows, available grade, and
anticipated land use. Several currently planned on-site sewer lines may also need to be extended during
final engineering to accommodate development of the individual blocks at multiple or alternative
connection points. The proposed system is described in greater detail under Threshold 3 below. Figure
3-11, Sewer System, illustrates the location of the proposed on-site sewer system. The proposed phasing
of the sewer system is provided in Figure 5.15-2.
The sewer pipeline would be installed using conventional construction practices, either open trench
excavation or a boring and jacking method. Installation of on- and off-site site sewer lines has the
potential to generate vehicle and equipment emissions and dust, increase noise levels, impact
undiscovered cultural resources, affect biologically sensitive habitats, contaminate groundwater, and
cause erosion. These issues have been addressed as part of the construction analyses presented in
Sections 5.4 Air Quality, 5.6 Biological Resources, 5.7 Cultural Resources, 5.11 Hydrology and Water
Quality, and 5.5 Noise. Mitigation measures are proposed in these sections to reduce construction
impacts to a less than significant level, with exception of air quality emissions from grading. Air pollutant
emissions from installation of infrastructure are included in the trenching phase of construction in Table
5.4-6, Maximum Daily Emissions per Construction Activity. As shown in this table, all air pollutant
emissions associated with installation of the underground utilities would be less than significant.

The proposed project could require sewage treatment capacity beyond the City's existing wastewater
treatment capacity rights and allocated additional treatment capacity. Implementation of respective
General Plan policies would ensure that treatment capacity would be provided by the City; however, the
means by which additional treatment capacity would be acquired is unknown. The City's options include
the acquisition of treatment capacity from a San Diego Metropolitan Sewer Authority member agency,
including the City of San Diego, or construction of a Chula Vista treatment facility. Final determination
on the means by which additional treatment capacity would be acquired has not yet been made. As the
location and scope of construction for any newly developed treatment facilities are unknown, and the
development of treatment capacity beyond the City's existing and allocated capacity may result in
impacts on the environment, it is conservatively concluded that a potentially significant environmental
impact associated with construction of new or expanded treatment facilities may occur.
C. Threshold 3: Generate sewage flows and volumes that exceed City
Engineering Standards as set forth in the Subdivision Manual, as may be
amended from time to time.
The proposed sewer facility improvements that would be required to serve Village 8 West were
developed by Dexter Wilson Engineering, Inc. and are provided in Appendix L. Sewer facility
improvements required to serve Village 8 West include on-site gravity sewer lines, including a temporary
deep sewer line, and an off-site connection to the Salt Creek Interceptor. Figure 3-11, Sewer System,
shows the conceptual sewer facilities. These facilities are summarized below.
The southern portion of the site would be served by constructing gravity sewer pipelines to convey flows
south to a single point of connection with the Salt Creek Interceptor. This would require approximately
2,000 feet of off-site 15-inch gravity sewer pipelines that would be located within the right-of-way for
the trail connection to the Otay Valley Regional Park. The northern portion of Village 8 West would drain
by gravity to the western boundary of the project site. A deep sewer line is proposed to convey flows to
the south to the gravity sewer system that would serve the project.
The maximum depth of cover over the sewer is approximately 50 feet. The deep gravity sewer would be
sized to convey on-site flows plus off-site flows from the Village 4 community park, Village 7, and the
EUC, as described below.
The SPA Plan has identified five phases of development. The order in which these phases will occur is
not yet known. The sewer service report for Village 8 West describes the sewer facilities that would be
required to serve each phase, assuming development of each phase would occurs independent of the
other project phases. Figure 3-18, Development Phases, graphically shows the proposed phasing of the
project. The required improvements are summarized below. Prior to the approval of the final map for
each phase, the sewer improvements described below would be required to be installed.
The Orange phase is located in the southwest corner of the site. This area of the site can be served by
constructing 8-inch through 15-inch gravity sewer lines. These lines will collect flows and convey them
south through Planning Area V and off site to the connection with the Salt Creek Interceptor.
The Blue phase is located in the southwest portion of the site. To serve this area, gravity sewer lines
would need to be installed in La Media Road, through Planning Area V, and off site to the connection
with the Salt Creek Interceptor.

The Purple phase is located in the southwest corner of the site. Development in this area can be served
by installing 8-inch through 15-inch gravity sewer lines and installing the off-site gravity sewer line to the
point of connection with the Salt Creek Interceptor.
The Yellow phase is located in the northern portion of the site. To provide sewer service to this area of
the site, gravity sewer lines ranging from 8-inch to 15-inch will need to be installed. This includes
extending a sewer line to the northern project boundary to serve the Village 4 community park and a
temporary deep gravity sewer line to divert flows from the northern portion of the project to the south.
Development of this phase would also require the installation of the gravity system in La Media Road,
through Planning Area V, and off site to a connection with the Salt Creek Interceptor.
The Green phase is located on the eastern side of the site. This area of the site can be served by
installing 8-inch through 15-inch gravity sewer lines. These lines will convey flow southerly through
planning Area V and off site to the connection with the Salt Creek Interceptor.
The on-site sewer system in the northern portion of Village 8 West would also be sized to accommodate
flows from the Village 4 community park, a portion of Village 7, and a portion of the EUC. Flows from
existing development in Village 7 and the EUC are currently being diverted to the Poggi Basin. The
gravity collection system for Village 8 West would include a stub to the northern project boundary in La
Media Road to allow the Village 4 community park site and a portion of Village 7 to be connected to this
system. The Village 4 community park is located at the northern boundary of Village 8 West. Average
flows from the portion of the park to the north of Village 8 West are estimated to be 22,100 gpd. The
proposed on-site gravity sewer line in La Media Road would be extended to the northern boundary of
the site to accommodate these flows. Development east of Magdalena Avenue in Village 7, which would
be conveyed to Village 8 West, generates an estimated 120,894 gpd. A maximum average flow of
660,297 gpd would be conveyed from the EUC to the Village 8 West sewer system. Flow from Village 7
and the EUC would connect to the Village 8 West system at the intersection of Main Street and
Magdalena Avenue.
Detailed calculations for the on-site sewer system are provided in the Overview of Sewer Service,
contained in Appendix L of this EIR. Since Village 8 West has the potential to develop in a variety of
ways, flow projections are based on the maximum buildout. Several on-site lines may need to be
relocated (with respect to the existing preliminary plan) during final engineering to accommodate
development of the individual blocks at multiple or alternative connection points.
The design of the proposed on-site system would be required to comply with the existing Subdivision
Manual, Section 3 (General Design Criteria) and would be subject to review by the City’s Engineering
Department. Compliance with regulatory design criteria would ensure that on-site lines would not
exceed 75 percent of pipe capacity for pipes greater than 12 inches in diameter or 50 percent for pipes
12 inches or less in diameter, including projected flows for the off-site developments that would be
served by Village 8 West infrastructure. Therefore, the project would be less than significant with
respect to this threshold.
D. Threshold 4: Be inconsistent with General Plan, GDP or other relevant
objectives and policies regarding wastewater, thereby resulting in a
significant physical impact.
Table 5.15-12 evaluated the project’s consistency with the General Plan policies related to wastewater
and Table 5.15-13 evaluated the project’s consistency with applicable GDP policies. The evaluations
demonstrate that the project would be consistent with applicable General Plan and GDP policies.

Objective PFS 2: Increase efficiencies in water use, wastewater
generation and its re-use, and handling of storm water runoff
throughout the city through use of alternative technologies.
Policy PFS 2.3: In designing water, wastewater, and drainage
facilities, limit the disruption of natural landforms and water
bodies. Encourage the use of natural channels that simulate
natural drainage ways while protecting property.
Consistent. The proposed sewer infrastructure would be
placed underground. No new storage facilities or other above
ground facilities would be required. Refer to the analysis of
the sewer system’s impact under Threshold 2. Installation of
the facilities would not significantly disrupt any natural
landforms or water bodies.
Objective PFS 4: Provide long-term wastewater treatment
capacity to meet the needs of existing and new development in
Chula Vista.
Consistent. Project development would be consistent with the
growth anticipated for Village 8 West and would not result in a
determination by the City of Chula Vista or San Diego
Metropolitan Sewer Authority that it has inadequate capacity
to serve the project’s demand in addition to the providers’
existing commitments. The PFFP for Village 8 West identifies
the appropriate funding mechanisms to support the City’s
provision of public services, including a future expansion of
waste water treatment capacity.
Objective GM 1: Concurrent public facilities and services. Consistent. Development in Village 8 West would be subject
to this policy. This objective provides the authority to impose
limits on the rate of development if adequate sewer treatment
facilities would not be available.
Objective GM 3: Create and preserve vital neighborhoods.
Policy GM 3.3: Assure that all new and infill development within
existing urban areas pays its proportional share of the cost for
urban infrastructure and public facilities required to maintain the
threshold standards, as adopted for its area of impact.
Consistent. See analysis for Objective GM 1.

Part II, Chapter 5 – Capital Facilities, Section C –Public Facility Plans
Goal: Provide a healthful and sanitary sewerage collection and
disposal system for the residents of Otay Ranch and the region,
including a system designed and constructed to accommodate
the use of reclaimed water.
Objective: The on-going planning, management and
development of sewerage conveyance, treatment and disposal
facilities to adequately meet future demands.
Policy: Land use planning will be coordinated with sewerage
system planning, which is the responsibility of facility providers.
Policy: Ensure that the Otay Ranch project will not use all
available regional facility capacity, such as sewer, water and
roads, and thus compromise the ability of other South County
and East County parcels to develop as planned.
Objective: Assure that wastewater treatment plans are
consistent with sewerage master plans.
Consistent. A sewer plan was developed for project, provided
as Appendix L, which includes the infrastructure required to
serve the entire project site, as well as by individual phase. The
infrastructure plan was developed based on the City’s
Wastewater Master Plan, which was updated by the
November 2010 Salt Creek Interceptor Technical Sewer Study
for the South Otay Ranch. The updated Wastewater Master
Plan factored Village 8 West into the city wastewater demand.
See also the analysis of impact on the city sewer system under
Thresholds 1, 2 and 3. The City currently has the capacity to
serve development of Village 8 West and has the authority
through the General Plan to withhold permits in the future if
adequate sewer capacity is not available.

5.15.2.4 Level of Significance Prior to Mitigation
A. Adequate Wastewater Facilities
A significant impact would occur if adequate wastewater facilities are not provided concurrently with
new demand. Additionally, the transfer of density between planning areas could have a significant
impact on on-site infrastructure.
B. New Wastewater Treatment Facilities
With respect to conveyance lines, no significant impacts have been identified for implementation of the
SPA Plan and TM. However, the proposed project would require sewerage treatment beyond the City’s
existing wastewater treatment capacity rights and allocated additional treatment capacity. Therefore,
additional capacity would need to be acquired from the San Diego Metropolitan Sewer Authority or
other sources. The means by which additional treatment capacity would be acquired is unknown and
the development of additional capacity may require construction of new treatment facilities. As the
location and scope of construction for any newly developed treatment facilities is unknown, the
development of treatment capacity beyond the City's existing and allocated capacity may result in a
potentially significant environmental impact, even understanding that such projects would likely be
subject to environmental review.
C. Consistency with City Engineering Standards
No significant impacts City engineering standards have been identified for implementation of the SPA
Plan and TM.
D. Consistency with Wastewater Policies
No significant impacts related to consistency with wastewater policies have been identified for
implementation of the SPA Plan and TM.

technical study shall demonstrate to the satisfaction of the City Engineer that adequate on -
site wastewater infrastructure will be available to support the transfer. The transfer of
residential density shall be limited by the ability of the on-site sewerage facilities to
accommodate flows.
B. New Wastewater Treatment Facilities
No mitigation measures are required for wastewater conveyance facilities in compliance with standards
are policies. The means by which additional capacity is obtained from the San Diego Metropolitan Sewer
Authority or other sources to support treatment city-wide is unknown at this time.
C. Consistency with City Engineering Standards
No mitigation measures are required.
D. Consistency with Wastewater Policies
No mitigation measures are required.
5.15.2.6 Level of Significance After Mitigation
A. Adequate Wastewater Facilities
With implementation of mitigation measures 5.15.2-1 through 5.15.2-3, no significant impacts with
respect to wastewater conveyance facilities would occur and adequate treatment capacity to serve new
development within Village 8 West would be ensured through review of available capacity by the City
Engineer prior to approval of building permits.
However, the project in combination with foreseeable growth may require sewerage treatment that
exceeds the City’s existing wastewater treatment capacity. Therefore, additional capacity may need to
be acquired from the San Diego Metropolitan Sewer Authority or other sources to support treatment
needs through the Year 2030. The means by which additional treatment capacity would be acquired is
unknown and could include the acquisition of available sewerage treatment capacity from another
participating agency, including the City of San Diego, or the construction of new treatment facilities. As

5.15.3 Solid Waste
5.15.3.1 Existing Conditions
A. Regulatory Framework
1. State
a. California Integrated Waste Management Act of 1989
The Integrated Waste Management Act of 1989 (PRC Section 4000, et.seq.) requires each city and
county in California to recycle or divert 50 percent (or as much as feasible) of its current waste stream
from landfills by 2000. In 2008, California diverted 60 percent of its solid waste stream in accordance
with the Integrated Waste Management Act (CIWMB 2009). The term “integrated waste management”
refers to the use of a variety of waste management practices to safely and effectively handle the
municipal solid waste stream with a minimum impact on human health and the environment. The
Integrated Waste Management Act establishes the following waste management priorities: source
reduction, recycling, composting, energy recovery, deposits in landfills, and household hazardous waste
management.
2. Local
a. City of Chula Vista General Plan
Objective PFS 25 of the Public Facilities and Services Element of the Chula Vista General Plan encourages
the city to “efficiently handle solid waste disposal throughout the city.” The General Plan policies related
to solid waste address city-wide methods to manage waste generation, permit transfer stations,
promote recycled materials and participate in interjurisdictional efforts to maintain available landfill
capacity. As such, the policies are regional in nature and do not specifically address individual
developments.

B. Existing Solid Waste Service
The Chula Vista Public Works Department, Environmental Services Division provides guidance in the
disposal of solid waste for residences and businesses, recycling, and household hazardous materials
disposal. Currently, Allied Waste Management Services is the exclusive solid waste and recycling services
provider for Chula Vista’s residential, commercial, and industrial waste. The City of Chula Vista Public
Works Department, Environmental Services Division also enforces a Special Event Recycling and Solid
Waste Management Plan in which a permit for special events requires a plan for litter control before,
during, and after a special event (City of Chula Vista 2009b).
The Environmental Services Division also provides a household hazardous waste program at the Public
Works Center in which household hazardous materials can be dropped off or picked up for a nominal
donation. Household waste collected at the city facility is sent to various locations throughout the
United States for treatment and/or recycling. The City has a mandatory construction and demolition
recycling program mandating that 90 percent of all inert materials (rock, dirt, concrete, brick, etc.) and
50 percent of all other debris be diverted from disposal (Municipal Code 15.12). Allied Waste provides a
construction and demolition debris processing facility to ensure that these materials are separated from
trash and recycled material (City of Chula Vista 2009b). Several processing facilities are currently
available in Chula Vista: untreated wood and mixed load recycling at Otay Landfill; dirt and rocks,
concrete, and asphalt recycling at the Reclaimed Aggregates facility at 855 Energy Way; and concrete
and asphalt recycling at the Rimrock CA, LLC facility at 2041 Heritage Road (City of San Diego 2010).
Per the City’s franchise agreement with Allied Waste, both the Otay Landfill and the Sycamore Canyon
Landfill are City-authorized landfills, in accordance with all applicable laws.
The Otay Landfill, located in Chula Vista, is a private landfill operated by San Diego Landfill Systems that
receives the majority of solid waste from the city. Based on permitted daily maximum disposal rates, the
Otay Landfill is expected to be in operation until 2028. Once the Otay Landfill is closed, it is anticipated
that a portion of the site could be used for a trash transfer facility and/or a material recovery facility
where recyclables are prepared for secondary markets. The City has also acquired rights to
approximately 30 acres of space at the Otay Landfill for a composting facility when the landfill closes.
Continued efforts to expand recycling and to accommodate compostable materials will reduce future
waste transfer costs (City of Chula Vista 2007). When the Otay Landfill closes, it is expected that Allied
Waste will build a transfer station at the Otay Landfill site to enable trash hauling to Sycamore Canyon
or a more distant landfill.
5.15.3.2 Thresholds of Significance
According to Appendix G of the CEQA Guidelines, the project would result in a significant impact to solid
waste services if it would:
■ Threshold 1: Would be served by a landfill with insufficient permitted capacity to accommodate
the project’s solid waste disposal needs.
■ Threshold 2: Does not comply with federal, state, and local statutes and regulations relating to
solid waste.
■ Threshold 3: Be inconsistent with General Plan, GDP, or other relevant objectives and policies
regarding solid waste thereby resulting in a significant physical impact.

City of Chula Vista
November 2013
5.15.3.3 Impact Analysis
A. Threshold 1: Would be served by a landfill with insufficient permitted capacity
to accommodate the project’s solid waste disposal needs.
The Otay Landfill has a total permitted capacity of 62.4 million cubic yards and has a permitted
remaining capacity of 33.1 million cubic yards (53 percent capacity). According to the 2013 GPA/GDPA
SEIR, buildout of the city under the General Plan would generate a solid waste disposal quantity of
274,063 tons, after which there would be 26.2 million tons of remaining landfill capacity. Based on the
city’s generation rate of 4.0 pounds per person per day, implementation of the 2013 GPA/GDPA,
including Village 8 West, would result in an additional disposal quantity of 22,433 tons above the 2005
General Plan projection. The Otay Landfill has sufficient capacity to accommodate the increased waste
disposal. The Otay Landfill is scheduled to close in 2028. However, an existing agreement will permit
waste from the city to be transferred to the Sycamore Canyon Landfill upon the closing of the Otay
Landfill. There would be no interruption of service (City of Chula Vista 2013).
Since there is sufficient existing and future landfill capacity to accommodate projected development of
the GPA/GDPA, impacts associated with insufficient permitted capacity to accommodate solid waste
disposal from Village 8 West would be less than significant, consistent with the conclusion of the 2013
GPA/GDPA SEIR.
B. Threshold 2: Does not comply with federal, state, and local statutes and
regulations relating to solid waste.
The City of Chula Vista’s Office of City Manager, Special Operations Division complies with state and
federal requirements through the development and the implementation of goals and policies in the
Public Facilities and Services and the Environmental Elements of the General Plan. General Plan policies
support and provide for city-wide recycling programs, including educational programs; source reduction
programs; the control of litter and solid waste associated with special events; and collection of
household hazards materials.
Landfills used for the disposal of Chula Vista’s solid waste are legally permitted and consistent with the
California Integrated Waste Management Board requirements and other state and federal
requirements. Waste collection for Village 8 West commercial and residential land uses would be
provided by the City of Chula Vista under its contract agreement with Allied Waste. The Village 8 West
waste collection procedures and programs would be required to comply with the municipal
requirements for recycling and collection of solid waste, including provision for litter control for public
events. Therefore, the project would be consistent with all applicable statutes and regulations, and
would have a less than significant impact with respect to solid waste collection and management.
C. Threshold 3: Be inconsistent with General Plan, GDP, or other relevant
objectives and policies regarding solid waste thereby resulting in a significant
physical impact.
Table 5.15-15 evaluates the consistency of the project with the applicable General Plan policies and
Table 5.15-16 evaluates the project’s consistency with that applicable GDP goal and objective. As shown
in these tables, the project would be consistent with the General Plan and GDP policies that pertain to
solid waste.

B. Existing Recycled Water Service
Historically, the only source of recycled water for the OWD has been the Ralph W. Chapman Water
Recycling Facility. This facility currently has a rated capacity of 1.3 mgd with a maximum production of
approximately 1.1 mgd and could be expanded to an ultimate capacity of 2.50 mgd. Typically, summer
demands exceed the 1.1 mgd plant capacity. OWD has the capability to supplement the recycled water
supply with the potable 980 Zone water system which has facilities in the area. The South Bay Water
Treatment Plant has an ultimate rated capacity of 15 mgd and the OWD obtained capacity rights to 6.0
mgd of recycled water. This additional source of recycled water will allow OWD to meet existing and
future recycled water demands. OWD has planned and begun constructing a series of pump stations,
reservoirs, and transmission lines to integrate this source of water into the existing recycled water
system. A 12-inch pipeline has been constructed beneath La Media Road to the north of Village 8 West
and an 8-inch line will be extended to the western and eastern boundaries for future extension by
others. Some piping may be required in the northeast corner of Village 8 West per the OWD Master Plan
but this line will not provide service to the project.
5.15.4.2 Thresholds of Significance
According to Appendix G of the CEQA Guidelines, the project would result in a significant impact to
recycled water services if it would:
■ Threshold 1: Require or result in the construction of new recycled water treatment facilities or
expansion of existing facilities, the construction of which could cause significant environmental
effects.
■ Threshold 2: Be inconsistent with General Plan, GDP, or other relevant objectives and policies
regarding recycled water thereby resulting in a significant physical impact.
5.15.4.3 Impact Analysis
A. Threshold 1: Require or result in the construction of new recycled water
treatment facilities or expansion of existing facilities, the construction of
which could cause significant environmental effects.
The OWD will also be the purveyor of recycled water to the project. The project would use recycled
water for landscape irrigation, including medians, parks, open space, and common landscaped areas.
The primary benefit of using recycled water is that it would offset potable water demand. Table 5.15-17
summarizes the recycled water demand for Village 8 West. As shown in this table, the estimated
recycled water demand is 0.14 mgd.
Recycled water would be provided to the project by extending the 680 Zone recycled water system from
the 12-inch line in La Media Road to the north. Some 927 Zone recycled water piping exists in the
northeast corner of the project but no 927 Zone service is proposed within Village 8 West. The slopes on
the western edge of the project that approach elevations of up to 600 feet will require private booster
systems at the landscape connections. Figure 3-10, Recycled Water System, provides the proposed on-
site recycled water system.

Installation of on- and off-site recycled water pipelines have the potential to generate vehicle and
equipment emissions and dust, increase noise levels, impact undiscovered cultural resources, disturb
biological resources, contaminate groundwater, and increase erosion. These issues have been addressed
as part of the construction analyses presented in Sections 5.4 Air Quality, 5.6 Biological Resources, 5.7
Cultural Resources, 5.11 Hydrology and Water Quality, and 5.5 Noise of this EIR. Mitigation measures
are proposed in these sections to reduce construction impacts to a less than significant level, with
exception of air quality impacts related to grading. Air pollutant emissions from installation of
infrastructure are included in the trenching phase of construction in Table 5.4-6, Maximum Daily
Emissions per Construction Activity. As shown in this table, all air pollutant emissions associated with
installation of the underground utilities would be less than significant. Therefore, construction of the
recycled water infrastructure required by buildout of the project would not result in significant
environmental effects. However, if the proposed recycled water facilities are not constructed, the
project would result in an additional impact related to water supply because a greater amount of
potable water would be needed. If recycled water facilities are not provided concurrently with demand,
a potentially significant impact would occur.
B. Threshold 2: Be inconsistent with General Plan, GDP, or other relevant
objectives and policies regarding recycled water thereby resulting in a
significant physical impact.
The evaluation in Table 5.15-18 demonstrates that the project would be consistent with General Plan
Policy E 3.3. The evaluation in Table 5.15-19 demonstrates that the project would be consistent with
applicable GDP goals and objectives. Therefore, this impact would be less than significant.

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System is a
certification program and the nationally accepted benchmark for the design, consumption, and
operation of high performance green buildings. LEED provides building owners and operators with the
tools they need for an immediate and measurable impact on their building’s performance. The LEED
green building certification program encourages and accelerates global adoption of sustainable green
building and development practices through a suite of rating systems that recognize projects that
implement strategies for better environmental and health performance.
b. California Code of Regulations Title 20 and Title 24
New buildings and major renovations constructed in California are required to comply with the
standards contained in Title 20, Energy Building Regulations, and Title 24, Building Energy Efficiency
Standards. The standards are updated periodically to allow consideration and possible incorporation of
new energy-efficiency technologies and methods. The Energy Commission adopted the 2008 changes to
the Building Energy Efficiency Standards for a number of compelling reasons (CEC 2012):
■ To provide California with an adequate, reasonably priced, and environmentally sound supply of
energy.
■ To respond to AB 32, the Global Warming Solutions Act of 2006, that mandates that California
must reduce its GHG emissions to 1990 levels by 2020.

■ To pursue California energy policy that energy efficiency is the resource of first choice for
meeting California's energy needs.
■ To act on the findings of California's Integrated Energy Policy Report that Standards are the most
cost effective means to achieve energy efficiency, expects the Building Energy Efficiency
Standards to continue to be upgraded over time to reduce electricity and peak demand, and
recognizes the role of the Standards in reducing energy related to meeting California's water
needs and in reducing GHG emissions.
■ To meet the West Coast Governors' Global Warming Initiative commitment to include
aggressive energy efficiency measures into updates of state building codes.
■ To meet the Executive Order in the Green Building Initiative to improve the energy efficiency of
non-residential buildings through aggressive standards.
Title 20 contains standards ranging from power plant procedures and siting to energy -efficiency
standards for appliances to ensure that reliable energy sources are provided and diversified through
energy efficiency and renewable energy resources.
Title 24 contains energy efficiency standards for residential and non-residential buildings based on a
state mandate to reduce California’s energy demand. Specifically, Title 24 addresses a number of energy
efficiency measures that impact energy used for lighting, water heating, heating, and air conditioning,
including the energy impact of the building envelope such as windows, doors, skylights, wall/ floor/
ceiling assemblies, attics, and roofs. The 2008 version of Title 24 includes standards that achieve a
minimum 15 percent improvement in energy efficiency over the previous 2005 Title 24 standards.
c. California Flex Your Power Campaign
California’s intent to reduce energy consumption is also reflected in the established Flex Your Power
Campaign. Flex Your Power aims to partner Californians across the state to maximize energy
conservation and efficiency. The goal is to get local governments and elected officials to implement
innovative energy conservation and efficiency measures in facilities throughout communities. Flex Your
Power collaborates with local businesses and community groups to get local business leaders and
building owners to sign an Energy Conservation Declaration Action, thereby committing to follow
measures that will help “achieve collectively an overall 20 percent reduction in energy use as compared
to the same period last summer.”
Some of the activities outlined in the declaration include setting building temperatures no cooler than
78 degrees during the months of May through October, reducing lighting levels by 25 percent, closing
blinds and shades where windows contribute to indoor temperature increases, and turning off and
unplugging all appliances in commercial and residential buildings. Businesses can also benchmark
buildings using the Energy Star rating system, which calculates energy use in a building or a group of
buildings, providing a tool with which to measure the impact of energy efficiency improvements. This
can provide a way to compare energy use in buildings of similar size, shape, location, and operating
characteristics. The results (a number on a scale of 1 to 100) determine which buildings will benefit most
from energy efficiency upgrades. By increasing energy efficiency in buildings, local governments can
save energy immediately.

a. SDG&E 20-Year Resource Plan
In April 2003, San Diego Gas & Electric (SDG&E) filed its 20-year resource plan with the California Public
Utilities Commission to outline its resource portfolio to meet future demand. The plan describes
SDG&E’s recommended resource portfolio and includes a number of policy recommendations that
SDG&E believes should be adopted by the California Public Utilities Commission as guidance for future
resource planning and procurement. The plan included four different portfolio proposals: one portfolio
emphasized on-system fossil generation; one emphasized resources delivered over added transmission;
another emphasized resources delivered over added transmission but builds in additional fuel diversity
by including an off-system coal based resource in the mix; and the fourth represented SDG&E’s
recommended balanced portfolio, which included the best elements of each of the prior three.
Resource gaps that would not be filled by energy conservation and demand response alternatives were
planned to be filled by additional transmissions lines from generating systems outside of SDG&E
territory, including renewable energy facilities. Using the Balanced Portfolio, SDG&E’s 2012 energy mix
would be comprised of roughly 14 percent Renewable, 53 percent Natural Gas, 14 percent Nuclear, and
19 percent Off-System Resources.
3. Local
a. Climate Change Working Group Measures – Implementation Plans
The Chula Vista Climate Change Working Group recommended seven measures to reduce city-wide GHG
emissions that were adopted by the City Council on April 1, 2008. Two of these measures would reduce
GHG emissions by reducing electricity and natural gas use. These measures include adopting a green
building standard, and providing cost-effective and streamlined mechanism for property owners to
implement solar and energy efficiency upgrades.
b. Chula Vista Green Building Standards
The Green Building Standards ordinance includes standards for energy efficiency. Building permit
applications are required to indicate on project construction plans and specifications the GBS measures
that comply with the ordinance. Prior to final building approval or issuance of a certificate of occupancy
the Building Official reviews the information submitted by the applicant and determines whether the
applicant has constructed the project in accordance with the permitted plans and documents, and
whether the plans are in compliance with the GBS.
c. City of Chula Vista Municipal Code Section 15.26, Energy Code
Since the adoption of the 2005 GPU EIR, the City adopted its Energy Code, Municipal Code sections
15.26, et seq. The Energy Code incorporates the requirements of the state’s 2008 energy code (i.e., Title
24), discussed above, with an additional requirement for increased energy efficiency standards to be
applied to most new development within the city (Section 15.26.030). The Energy Code went into effect
on February 26, 2010. There are several different volumes of information that make up the Energy Code
including:
■ Building Energy Efficiency Standards for Residential and Non-Residential Buildings. This
volume is the actual Energy Code text.

■ Residential Compliance Manual. This volume is intended to help owners, designers, builders,
inspectors, plans examiners, and energy consultants comply with and enforce building energy
efficiency standards for low-rise (3 stories or less) residential buildings.
■ Non-Residential Compliance Manual. This volume is intended to help owners, designers,
builders, inspectors, plans examiners, and energy consultants comply with and enforce building
energy efficiency standards for non-residential, high-rise residential and hotel/motel buildings.
■ Reference Appendices. This volume contains the testing standards and methods as well as the
background and support information used throughout the Energy Code package.
■ Residential Compliance Forms
■ Non-Residential Compliance Forms
Energy efficiency reduces energy costs, increases reliability and availability of electricity, improves
building occupant comfort, and reduces impacts to the environment. All building permits applied for and
submitted after February 2010 are subject to these increased energy efficiency standards. The increase
in energy efficiency is a percentage above the 2008 Title 24 energy code and is dependent on Climate
Zone and type of development proposed. The project area is located withi n Climate Zone 7. Generally,
new residential and non-residential projects within the project area must be at least 15 percent more
energy efficient than the 2008 Title 24 energy code.
d. Chula Vista Climate Adaptation Strategies – Implementation Plans
The Climate Adaptation Strategies – Implementation Plans document developed by the Climate Change
Working Group includes eleven strategies to adapt Chula Vista to the potential impacts of global climate
change, including energy supply. The strategies to reduce energy demand include cool paving, shade
trees, and cool roofs. For each strategy, the plans outline specific implementation components, critical
steps, costs, and timelines. In order to limit the necessary staffing and funding required to implement
the strategies, the plans were also designed to build upon existing municipal efforts rather than create
new, stand-alone policies or programs. Initial implementation of all eleven strategies is intended to be
phased in over a three year period from plan adoption.
e. San Diego Regional Energy Efficiency Plan/City of Chula Vista Energy Strategy and Action Plan
The San Diego Regional Energy Plan provided policy and program recommendations to achieve energy
sustainability and security (SANDAG 1994). The San Diego Regional Energy office worked with SANDAG
to update the plan with Energy 2030, the San Diego Regional Energy Strategy. The Regional Energy
Strategy is intended to create a vision of how energy will be produced and consumed in the San Diego
region in 2030. It also provides an integrated approach to meeting energy needs and ensures that an
adequate supply and distribution of electricity, natural gas and transportation fuels is available.
The City has adopted an energy plan to address long-term energy issues and to protect its residents
from unreliable energy supply and volatile prices. The plan, called the Chula Vista Energy Strategy and
Action Plan, addresses demand side management, energy efficient and renewable energy outreach
programs for businesses and residents, energy acquisition, power generation, and distributed energy
resources and legislative actions (City of Chula Vista 2001a).
f. City of Chula Vista Solar Ready Ordinances
CVMC Section 15.28.015, solar water heater pre-plumbing, and Section 15.24.065, photovoltaic pre-
wiring requirements, are referred to as the Solar Ready ordinances. Section 15.28.015 requires all new

residential units to include plumbing specifically designed to allow the later installation of a system
which utilizes solar energy as the primary means of heating domestic potable water. Section 15.24.065
requires all new residential units to include electrical conduit specifically designed to allow the later
installation of a photovoltaic system which utilizes solar energy as a means to provide electricity.
g. City of Chula Vista General Plan
The Chula Vista General Plan recognizes that to ensure adequate and reliable energy service, efficient
energy efforts throughout the city and transitioning to non-fossil fuel alternatives will help to extend
limited supplies, reduce the need for expensive new regional power generators and transmission lines,
and contribute to Chula Vista’s economic sustainability and regional competitiveness. The General Plan
includes objectives in the Public Facilities and Services Element to ensure adequate energy supplies
throughout Chula Vista (Objective PFS 22) and integrate sensible and efficient electrical and natural gas
facilities into the natural and developed environment (Objective PFS 23).
h. Otay Ranch General Development Plan
Part II, Chapter 10 establishes goals, objectives, and policies to ensure the conservation of significant
portions of Otay Ranch's natural environment. Overall, these goals, objectives and policies prevent the
wasteful exploitation, destruction, or neglect of resources and encourage the preservation
enhancement and management of sensitive resources. Specifically, Section E addresses the overall goal
of establishing Otay Ranch as a “showcase” for the efficient utilization of energy resources and the use
of renewable energy resources.
■ Objective: Reduce the use of non-renewable energy resources within Otay Ranch below per
capita non-renewable energy consumption in San Diego County.
Policy: Prepare a non-renewable energy-conservation plan for each SPA.
■ Objective: Provide land use patterns and project features which result in the conservation of
non-renewable energy resources.
Policy: Reduce the reliance for project residents to utilize the automobile, thereby minimizing
automobile trips and miles traveled. Encourage the provision of regional mass transit facilities
within the Otay Ranch.
B. Existing Energy Demand
As discussed in the 2013 GPA/GDPA SEIR, existing energy use in Chula Vista consists of fixed uses, such
as homes and businesses and mobile uses primarily cars and trucks. The discussion of energy demand
from each of these uses is provided below.
1. Fixed Uses
a. Electricity
Electricity is provided by SDG&E, who is the owner and operator of electricity transmission, distribution,
and natural gas distribution infrastructure in the county. Power generation and power use are not linked
geographically. In other words, power generated within the city is not dedicated to users in the city.
Electricity generated is fed into the statewide grid and is generally available to any users statewide.
Electricity consumption in the San Diego region varies greatly by type of use. In 2010, the city consumed
approximately 872 million kilowatt-hours (kWh) (City of Chula Vista 2012e). As mirrored in the county,

Otay Ranch Village 8 West EIR
CV EIR 10-03; SCH No. 2010062093 Page 5.15-44
City of Chula Vista
November 2013
the largest electricity consumption was from commercial uses, followed by residential, industrial, and
agriculture. Average energy consumption rates are based on CARB’s 2011 California Emissions Estimator
Model (CalEEMod) obtained from the CEC end-use surveys for residential and non-residential uses. For
ease of comparison, all rates have been calculated into annual rates. Table 5.15-20 shows average
existing annual consumption rates.
Table 5.15-20 Average Existing Energy Consumption Rates
Land Use Type Electricity Natural Gas
Residential 7,090.56.0 kWh/single-family unit
4,324.68 kWh/multi-family unit
62,384.40 cubic feet/single-family unit
37,547.64 cubic feet/multi-family unit
Schools 6.35 kWh/square feet 15.50 cubic feet/square feet
Commercial 14.10 kWh/square feet 34.8 cubic feet/square feet
Industrial ( Regional Technology Park) 17.6 kWh/square feet 2,899,332 cubic feet/consumer/year
Community Purpose Facility 9.38 kWh/square feet 33.20 cubic feet/square feet
Parks 9.38 kWh/square feet 3.0 cubic feet/square feet
Source: City of Chula Vista 2013
b. Natural Gas
Natural gas imported into southern California originates from any of a series of major supply basins
located from Canada to Texas. Although the San Diego region has access to all of these basins by
interstate pipeline, the final delivery into the SDG&E system is dependent on only one gas pipeline.
Several liquefied natural gas plants are proposed in Mexico, which would provide an additional source of
natural gas to southern California.
In general, power plants account for the highest percentage of natural gas consumption in the San Diego
region. Residential consumption of natural gas is the second highest percentage, followed by co-
generation, commercial consumption, industrial consumption, and natural gas vehicles. In 2010, the city
consumed approximately 48 million therms of natural gas (City of Chula Vista 2012e).
Natural gas consumption for this analysis is likewise calculated using rates obtained from CARB’s 2011
CalEEMod. Table 5.15-20 shows average existing annual consumption rates for natural gas.
2. Mobile Uses
Roughly half of the energy Californians consume is for transportation. In 2007, Californians consumed an
estimated 20 billion gallons of gasoline and diesel fuel on the state's roadways, an increase of nearly 50
percent over the last 20 years. Nearly 26 million registered vehicles operating in California produce
about 40 percent of the state's GHG emissions (CEC 2010).
5.15.5.2 Thresholds of Significance
According to the City of Chula Vista, the project would result in a significant impact to energy resources
if it would:
■ Threshold 1: Increase the demand of energy resources to exceed the available supply or cause a
need for new and expanded facilities.
■ Threshold 2: Result in the wasteful, inefficient, or unnecessary use of energy.

■ Threshold 3: Be inconsistent with General Plan, GDP, or other relevant objectives and policies
regarding energy thereby resulting in a significant physical impact.
5.15.5.3 Impact Analysis
A. Threshold 1: Increase the demand of energy resources to exceed the
available supply or cause a need for new and expanded facilities.
A significant impact to energy resources would occur if implementation of Village 8 West would result in
a demand for energy that would exceed the city’s available supply or cause a need for new and
expanded facilities. Table 5.15-21 provides for the projected energy demand for Village 8 West.
Adjustments to the existing rates of average energy consumption were made in these calculations to
reflect improvements in energy-efficient building design due to the 2008 Title 24 updates (which
became effective January 2010) and the new Increased Energy Efficiency Standards of the city Energy
Code (which became effective February 2010). Combined, these increased energy-efficiency
requirements would achieve 30 percent less energy consumption for the project compared to existing
average rates of energy consumption. This 30 percent reduction is based on the 15 percent increase in
energy efficiency in building design required in the 2008 Energy Code plus an additional 15 percent
energy improvement required by the Chula Vista Increased Energy Efficiency Ordinance (City of Chula
Vista 2013). As shown in Table 5.15-21, Village 8 West would increase electricity demand by 11.2 million
kWh and natural gas demand by 37.3 million cubic feet.

The Climate Change Working Group’s recommendations to reduce energy use are actions for the City to
implement and do not include any measures to be implemented by individual projects. However, the
project would be required to comply with any ordinances that are adopted as a result of the
recommendations. At a minimum, future development in Village 8 West would be required to meet the
mandatory energy standards of the Chula Vista Green Building Standards (Ordinance No. 3140), the
Chula Vista Energy Code (Municipal Code Sections 15.26, et seq.) and current CCR Titles 24, Part 6
California Energy Code, Part 11 California Green Building Standards, and the Chula Vista Energy Code
includes Increased Energy Efficiency Standards (Municipal Code Section 15.26.030). These standards
require projects to use 15 to 20 percent less energy than the California Energy Code requires, d epending
on climate zone. Village 8 West lies within the climate zone that requires 15 percent increased energy
efficiency. Additionally, some of the recommendations of the Climate Change Working Group’s
Adaptation Strategies have been incorporated into the SPA Plan. The SPA Plan encourages shared

parking and parking structures that would minimize expansive paved areas for parking lots, requires
streetscaping that would include shade trees and other vegetation, and encourages the use of cool
roofs, photovoltaics, and other energy saving materials and features.
To further address energy efficiency, the city also participates in the LEED Rating System and private
developments are strongly encouraged to utilize green building practices. The city’s adoption of the
Green Building Standards Ordinance in 2009 represented early adoption of the now-effective (as of
January 1, 2011) California Green Building Standards. Respective to energy efficiency, these standards
mandate 20 percent less water use than currently required by the state plumbing code.
The City’s Landscape Water Conservation Ordinance calls for greater efforts at water conservation and
more efficient use of water in landscaping. Because energy consumption is embodied in the acquisition,
treatment and distribution of water resources, less water consumption yields less energy consumption.
Development would also be required to comply with the Chula Vista Solar Ready ordinances, which
would encourage the use of solar energy.
As required by the Otay Ranch GDP, the SPA Plan includes a non-renewable energy conservation plan
addressing preservation of energy resources. This includes the development of land use patterns and
project features which reduce the reliance for project residents to utilize the automobile, encourage the
use of regional mass transit facilities, and reduce fossil fuel consumption through better siting and
design. Application of the city Energy Code, requiring a 15 percent less energy use than the state 2008
Energy Code, would add to the overall decrease in energy use throughout the project area. Therefore,
average energy consumed by future occupants of Village 8 West would not be excessive, and would in
fact be less than the regional average and less than statewide business-as-usual projections made by the
CARB as part of its GHG emissions forecasting.
Although these programs and policies would result in more efficient use of energy, they do not ensure
that increased resources will be available when needed. SDG&E has indicated that without an increased
import capacity, including a new substation within the Otay Ranch area, future energy needs could not
be assured. The new substation would be located in the EUC, south of the east end of Hunte Parkway.
Construction of the substation is expected to begin in late 2014 and is expected to be placed in service
in late 2015 (SDG&E 2012). The 120 megavolt amperes substation would provide infrastructure
necessary to provide power to buildout of Otay Ranch, but would not generate electricity or guarantee
that adequate supply would be available. Therefore, consistent with the conclusion of the 2013
GPA/GDPA SEIR, because there is still no assurance of a long-term supply of energy in the future, the
increase in energy consumption associated with the project would be significant.
B. Threshold 2: Result in the wasteful, inefficient, or unnecessary use of energy.
As discussed above, future development in Village 8 West would be required to meet the mandatory
energy standards of the Chula Vista Energy Code, current CC R Titles 24, Part 6 California Energy Code,
Part 11 California Green Building Standards, and the Chula Vista Energy Code. Additionally, the SPA Plan
includes a non-renewable energy conservation plan addressing preservation of energy resources.
Compliance with these policies and the energy conservation plan would ensure that average energy
consumed by future occupants of Village 8 West would not be wasteful, inefficient, or unnecessary, and
would in fact be less than the regional average and less than statewide business-as-usual projections.
Therefore, this impact would be less than significant.

C. Threshold 3: Be inconsistent with General Plan, GDP, or other relevant
objectives and policies regarding energy thereby resulting in a significant
physical impact.
Table 5.15-22 evaluates the consistency of the project with the applicable General Plan policies and
Table 5.15-23 evaluates the project’s consistency with applicable GDP goals and objectives. As shown in
these tables, the project would be consistent with the General Plan and GDP policies that pertain to
energy.
Table 5.15-22 Project Consistency with Applicable General Plan Energy Policies

Objective E 7: Promote energy conservation through the
efficient use of energy and through the development of local,
non-fossil fuel-based renewable sources of energy.
Policy E 7.1: Promote development of regulations and building
design standards that maximize energy efficiency through
appropriate site and building design and through the use of
energy-efficient materials, equipment, and appliances.
Consistent. As discussed in Section 5.10, Global Climate
Change, Village 8 West would be subject to the California
Green Building Standards and the Chula Vista Green Building
and Increased Energy Efficiency ordinances of the city
municipal code. Additionally, the SPA Plan includes a Non-
Renewable Energy Conservation Plan that identifies feasible
methods to reduce the consumption of non-renewable energy
resources, including methods for land use and community
design, building siting and construction techniques, and the
transit facilities and alternative transportation modes.
Objective H 2: Promote efficient use of water and energy
through adopted standards and incentive-based policies to
conserve limited resources and reduce long-term operational
costs of housing.
Policy H 2.1: Encourage the efficient use and conservation of
water by residents.

Part II, Chapter 6 – Air Quality
Objective: Minimize fossil fuel emission by conserving energy. Consistent. As discussed in Section 3.3.1(C), Mobility, Village 8
West is designed to provide alternate modes of travel and
reduce vehicle trips to reduce fossil fuel emissions.
Part II, Chapter 10 – Resource Protection, Conservation and Management
Goal: Establish Otay Ranch as a “showcase” for the efficient
utilization of energy resources and the use of renewable
energy resources.
Objective: Reduce the use of non-renewable energy resources
within Otay Ranch below per capita non-renewable energy
consumption in San Diego County.
Policy: Prepare a non-renewable energy-conservation plan for
each SPA.
Consistent. The design of Village 8 West encourages walking,
bicycling, and public transit use to lower fuel consumption. A
non-renewable energy conservation plan is included in the SPA
Plan and will contribute to efficient use of resources.

5.15.5.4 Level of Significance Prior to Mitigation
A. Energy Resources
While energy consumed by future occupants of Village 8 West would not be excessive, implementation
of the SPA Plan and TM has the potential to result in impacts due to increased consumption of electricity
and natural gas above that analyzed in the 2005 GPU EIR, which identified a significant and unavoidable
impact related to energy demand. Although development pursuant to the project would be required
comply with state and city building and energy codes and regulations related to reduction in energy use,
there is no long-term assurance that energy supplies will be available as needed to support subsequent
development projects. Therefore, impacts associated with energy consumption would be significant.
B. Wasteful Use of Energy
No significant impacts related to wasteful use of energy have been identified for the project.
C. Consistency with Energy Policies
No significant impacts related to consistency with energy policies have been identified for the project.
5.15.5.5 Mitigation Measures
A. Energy Resources
The 2013 GPA/GDPA SEIR included mitigation measure 5.3.5-1, as identified in the 2005 GPU EIR, to be
incorporated into future SPA plans to reduce impacts related to energy use. This plan required
continued focus on the Energy Strategy and Action Plan and continued implementation of the
Adaptation Strategies to lessen the impacts from energy. The project is consistent with this mitigation
measure because it includes a non-renewable energy conservation plan to reduce energy use.
Implementation of this plan would reduce average energy consumption, but would not guarantee that
future energy supplies will be available as needed to support future development project. No mitigation
measures are available that would guarantee future energy supplies.
B. Wasteful Use of Energy
No mitigation measures are required.
C. Consistency with Energy Policies
No mitigation measures are required.
5.15.5.6 Level of Significance After Mitigation
A. Energy Resources
Consistency with 2013 GPA/GDPA SEIR mitigation measure 5.3.5-1, along with the programs and policies
identified above, would reduce impacts to energy resources; however, because there is no assurance
that energy resources will be available to adequately serve the projected increase in population
resulting from the project, impacts would remain significant and unmitigated.
