EXECUTIVE SUMMARY
The City of Chula Vista's Growth Management Ordinance (CVMC 19.09.050C) requires
that all development projects with 50 dwelling units or greater prepare a Water
Conservation Plan (WCP) at the time of the Sectional Planning Area (SPA) plan
preparation. A WCP was prepared for the Freeway Commercial (FC) project when the
project was originally approved in 2002 and updated in 2019 when the SPA was amended
for the northern portion of the SPA. This plan presents a review of presently available
technologies and practices which result in water conservation in primarily residential
development. This report presents an updated WCP with measures that will be
incorporated into the planning and design of the Otay Ranch Town Center SPA, including
the requirements outlined in the Chula Vista Landscape Water Conservation Ordinance
(CVMC 20.12).
The FC SPA consists of the FC 1 site (Otay Ranch Town Center) which has been developed
as commercial per the originally approved SPA plan, the FC 2 site that was approved in
2019 and under-construction, and an update to FC 1 site to add approximately 840
residential units. This updated water conservation plan is limited to the FC 1 site. Town
Center Drive, which bisects the FC 2 site, was constructed concurrent with the FC 1 site
development.
The FC 1 site consists of 87.25 acres of property that is entitled for commercial uses. The
SPA Amendment would rezone 16.57 acres from FC to Mixed-Use/Residential (MU/R) to
allow up to 840 dwelling units. The rezone would reduce the allowed commercial space
from 960,000 to 816,000 square-feet – a reduction of 144,000 square-feet.
The Otay Water District is the local water agency that supplies potable water and recycled
water to the Otay Ranch Town Center. The current total estimated average potable and
recycled water use for the project is 0.26 mgd and 0.02 mgd, respectively.

The federal, state, and local governments have mandated a number of water conservation
measures. The project will install hot water pipe insulation, pressure reducing valves, and
water efficient dishwashers in all multi-family residential units. Additionally, the builder
will install dual flush toilets and other water conserving irrigation equipment and
techniques in compliance with the Landscape Water Conservation Ordinance. At buildout
of the project, implementation of the above measures along with the use of recycled water
would reduce estimated potable water usage on the project by an approximate 42,105 gpd.

INTRODUCTION
In recent years, the subject of water conservation has been given increased attention. The
growing awareness of the need and value of water conservation has been sparked by local
and regional water purveyors concerned about meeting the future water demands of their
customers, particularly during drought conditions. Water conservation provides an
alternative approach to the problem of finding new water sources to meet the water
demand for a proposed community. The intent of water conservation is to manage water
demand so that the customers receive adequate service but use less water.
Much has been done to educate consumers about limitations of water supply, the serious
implications of a long-term drought and the need for water conservation, but there is a
practical limit to the percentage reduction of water use in established communities. This
limit is a result of the types of plumbing fixtures installed in existing homes as well as the
difficulty in altering consumers' established patterns of water use. Any water conservation
effort, voluntary or mandatory, requires the cooperation of the public. Public information
should be utilized to inform and convince the consumer that a change in personal water use
habits is in everyone's best interest.
The private development sector has become more attuned to the concerns of water
availability and has recognized the value of addressing water conservation issues
throughout planned development projects. By incorporating low water use plumbing
fixtures, promoting drought tolerant landscaping, and providing educational materials to
homeowners within the development project, private developments can do much to cultivate
an interest in water conservation and establish new patterns of water use. These efforts
can have significant impacts with regard to reducing the need for securing and importing
larger quantities of water for use in San Diego County.
In 2006, the State repealed the Water Conservation in Landscaping Act and adopted a new
Water Conservation in Landscaping Act, Government Code Sections 65591 et seq. The new
Act requires the Department of Water Resources to update the previously adopted model
water efficient landscape ordinance that provides for greater efforts at water conservation
and more efficient use of water in landscaping. The modeled ordinance was required to
include provisions for: 1) water conservation by the appropriate use and groupings of plants
June 22, 2023
Otay Ranch Town Center Water Conservation Plan
DEXTER WILSON ENGINEERING, INC. PAGE 4
that are well adapted to particular sites and local conditions, 2) a landscape water budget
that establishes the maximum amount of water to be applied through the irrigation system,
3) automatic irrigation systems and irrigation schedules based on climatic conditions,
terrains and soil types and other environmental conditions, 4) onsite soil assessment and
soil management plans that include grading and drainage to promote healthy plant growth
and prevent excessive erosion and runoff, and 5) promoting the use of recycled water for
landscaping when it is available and the use is consistent with State law.
Government Code Section 65595 requires that on or before January 1, 2010 a local agency
shall adopt a water efficient landscape ordinance that is at least as effective in conserving
water as the updated model ordinance or adopt the model ordinance. The City of Chula
Vista Landscape Water Conservation Ordinance went into effect on January 1, 2010 and
requires homeowners to be efficient with the landscape systems and plant selection.
The City of Chula Vista ordinance complies with the findings and declarations of the State’s
Water Conservation in Landscaping Act and is as effective as the State’s updated model
water efficient landscape ordinance. This water conservation plan incorporates the
requirement of the City’s ordinance.
The Otay Ranch Freeway Commercial project is within the Otay Ranch General
Development Plan (Otay Ranch GDP). The Otay Ranch GDP was adopted in 1993 and
included objectives for water conservation to be incorporated into the development of Otay
Ranch. These objectives included the implementation of water efficient fixtures, increased
use of drought tolerant landscaping, and use of recycled water for irrigation. The objective
of these measures is to reduce the per capita water use within Otay Ranch by 25-percent as
compared to county wide 1989, per capita levels. This report will demonstrate how the
City, in partnership with the Otay Water District and development community are meeting
these objectives.

PURPOSE
The State Legislature determined in the Water Conservation in Landscaping Act that the
State’s water resources are in limited supply. The Legislature also recognized that while
landscaping is essential to the quality of life in California, landscape design and
maintenance must be water efficient. The City of Chula Vista’s Growth Management
Implementation Manual requires Water Conservation Plans for 1) all major development
projects of 50 dwelling units or greater; 2) commercial and industrial projects with 50 EDUs
or greater; and 3) all SPA Plans and Tentative Maps. The City has adopted guidelines for
the preparation and implementation of required Water Conservation Plans.
This report will present water conservation measures which will be incorporated into the
planning and design of the project, including an estimate of the anticipated water savings.
Approximately half of the water used by residences in California is used outdoors. For this
reason, the City's Landscape Water Conservation Ordinance will be an important
component of reduced water usage.
Although not covered in detail, there are several secondary benefits to conserving water
that should be kept in mind when reviewing material in this report. These benefits include
reduced sewage flows, reduced natural gas use, and reduced electricity use. Using less
water in the shower, for example, reduces the amount of water input into the sewer system
which requires treatment and disposal and reduces the amount of energy required to heat
the water.

WATER SERVICE AND SUPPLY
The Otay Water District is the local water agency that supplies potable water and recycled
water to the Otay Ranch Town Center. The Otay Water District relies solely on the San
Diego County Water Authority (SDCWA) for its potable water supply. The SDCWA is the
largest of 27-member agencies of the Metropolitan Water District of Southern California
(MWD), which is the primary importer of domestic water in Southern California.
PROJECTED WATER USE
Potable Water Demand
Potable water use is estimated by taking the acreage for each land use category and
multiplying by the corresponding water use factor. Table 2 provides the projected potable
water demand for the Otay Ranch Town Center Redevelopment. The total estimated
potable water use is 0.26 mgd. Potable water use factors were taken from the 2015 Otay
Water District Water Facilities Master Plan.

LOCAL WATER CONSERVATION REQUIREMENTS
There are a number of water conserving measures required by the Otay Water District and
City of Chula Vista Landscape Manual. These include the use of recycled water for the
irrigation of open space slopes and common landscaped areas where feasible. The
Landscape Manual also requires some drought tolerant plant selection in the landscaping
plan and the use of evapotranspiration controllers for parks and common landscaped areas.
Additionally, the City of Chula Vista Landscape Water Conservation Ordinance that was
updated on January 1, 2015 is expected to reduce outdoor water consumption due to the
setting of strict water budgets on City approved landscape plans that must not be exceeded.
The City of Chula Vista Water Conservation Plan Guidelines requires the following three
indoor water conservation measures for non-residential units. These measures are
mandatory.
Residential Measures - Mandatory
1. Hot Water Pipe Insulation. This measure involves the insulation of hot water pipes
with 1-inch walled pipe insulation and separation of hot and cold water piping. This
measure is estimated to cost an additional $50 during initial construction and result
in annual savings of 2,400 gallons per residential unit.
2. Pressure Reducing Valves. Setting the maximum service pressure to 60 psi reduces
any leakage present and prevents excessive flow of water from all appliances and
fixtures. This measure is estimated to cost $100 during initial construction and
result in annual water savings of 1,800 gallons per residential unit.
3. Water Efficient Dishwashers. There are a number of water efficient dishwashers
available that carry the Energy Star label. These units cost an additional $500 on
average and result in an estimated yearly water savings of 650 gallons per
residential unit.
June 22, 2023
Otay Ranch Town Center Water Conservation Plan
DEXTER WILSON ENGINEERING, INC. PAGE 11
In addition, to comply with the City's current water conservation requirements, the
developer must select at least one outdoor measure and one additional indoor or outdoor
water conservation measure for residential development and non-residential development.
Water conservation measures not included on the City's Residential Water Conservation
Measures list may be proposed by the developer. Since this project does not propose any
single-family residences, all outdoor irrigation water use is proposed to be met with
recycled water. Thus, there are no outdoor water measures that would result in a direct
reduction in potable water use.
The developer will implement, from the City's list of approved measures, the following
indoor non-mandatory measure in multi-family residential units and non-residential units.
1. Dual Flush Toilets. The developer will install dual flush toilets within the project.
This measure is estimated to cost $200 per household and result in annual water
savings of 4,000-gallons per year per residential unit.
WATER CONSERVATION ESTIMATED SAVINGS
The estimated water savings for water conservation measures are based on the estimates
provided in the previous section of this report. The potential water savings varies widely
based on land use types. Multi-family residential units, for example, have much less
opportunity to implement additional water saving measures than low density single family
residential units. This is primarily because the common landscaped areas of multi-family
units are required to be irrigated with recycled water and, thus, there are no outdoor water
conservation measures that can directly offset potable water usage in these areas.
Table 5 summarizes the total estimated water savings for the Otay Ranch Town Center
SPA Amendment based on the proposed required measures and non-mandatory measure
described above.

Water Conservation Summary
As detailed in this report, the Otay Ranch Town Center project is committed to being water
efficient through the use of recycled water for irrigation and utilizing other water
conservation devices and measures. Table 6 summarizes the baseline potable water use if
recycled water and water conservation measures were not utilized and provides the
anticipated water savings outlined in this report. As shown, the use of recycled water and
other water conservation measures is expected to reduce potable water usage by 42,105
gpd, or 15.1 percent.
