SUBJECT: Award of As-Needed Utility Locating Services Contract to AIRX
Utility Surveyors, Inc. for Fiscal Years 2018 through 2020
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board)
award a professional As-Needed Utility Locating Services contract to
AIRX Utility Surveyors, Inc. (AIRX) and to authorize the General
Manager to execute an agreement with AIRX in an amount not-to-exceed
$500,000 for a period of three (3) Fiscal Years (FY), FY 2018
through FY 2020 (ending June 30, 2021).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board authorization for the General Manager to enter into
a professional As-Needed Utility Locating Services agreement with
AIRX in an amount not-to-exceed $500,000 for FY 2018 through FY 2020
(ending June 30, 2021).

ANALYSIS:
California Government Code 4216 requires operators of subsurface
installations (including water and sewer facilities) to be a member
of the DigAlert Regional Notification Center which includes the
District’s Underground Service Alert (USA) of Southern California
program. As a member, operators are required to locate and field
mark their subsurface installations within two days of receiving
timely notification. To meet this legal requirement and support the
District’s USA program, the District will require the services of a
professional utility locating services consultant for three (3)
fiscal years, FY 2018 through FY 2020 (ending June 30, 2021). It is
more efficient and cost effective to augment District staff by
issuing an as-needed contract for utility locating services, which
will provide the District with the ability to obtain consulting
services in a timely and efficient manner. This concept has also
been used in the past with other disciplines such as engineering
design, construction management, electrical, and environmental
services.
The District has used an as-needed contract for utility locating
services over the previous six (6) fiscal years. The annual effort
of the As-Needed Utility Locating Services, used to support the
District’s USA Mark-out program from July 2015 through June 2017,
averaged hours that equated to less than a full-time employee (FTE)
at a rate of 0.85 FTE per year. An analysis of the USA workload for
FY 2018 through FY 2020 indicates a steadily increasing level of
effort from prior years will be needed for utility locating
services. It is estimated this steadily increasing level of effort
will equate to a rate of 1.4 FTE per year. Staff will recommend
budgeting for an additional employee during the FY 2019 budget
process.
The District will issue task orders to the consultant for specific
projects during the contract period based on a detailed scope of
work. The consultant will then prepare a schedule and fee estimate
for each task order assigned under the contract. Upon written task
order authorization from the District, the consultant shall then
proceed with the project, as described in the scope of work.
This As-Needed Utility Locating Services contract does not commit
the District to any expenditure until a task order is approved to
perform work on a USA project. The District does not guarantee work
to the consultant, nor does the District guarantee that it will
expend all of the funds authorized by the contract for professional
services.
3
The District solicited for utility locating services by placing an
advertisement on the Otay Water District’s website on September 5,
2017 and with various other publications including the San Diego
Daily Transcript. Seven (7) firms submitted a Letter of Interest
and a Statement of Qualifications. The Request for Proposal (RFP)
for As-Needed Utility Locating Services was sent to the seven (7)
firms resulting in three (3) proposals received by September 27,
2017.
AIRX Utility Surveyors, Inc., Escondido, CA
Cable Pipe and Leak Detection, Inc., El Cajon, CA
C Below, Chino, CA
The four (4) firms that chose not to propose are Encompass
Inspections, Temecula, CA, Kana Subsurface Engineering, Riverside,
CA, SPEC Services Inc., Fountain Valley, CA, and Superior Leak
Detection, Upland, CA.
In accordance with the District’s Policy 21, staff evaluated and
scored all written proposals and interviewed the top two (2) firms
on October 24, 2017. AIRX received the highest score for their
services based on their experience, understanding of the scopes of
work, proposed method to accomplish the work, and their composite
hourly rate. AIRX was the most qualified consultant with the best
overall rating or ranking scores. A summary of the complete
evaluation is shown in Attachment B.
AIRX submitted the Company Background Questionnaire as required by
the RFP and staff did not find any outstanding issues. In addition,
staff checked their references and performed an internet search on
the company. Staff found the references to be excellent and did not
find any outstanding issues with the internet search. AIRX is
providing these services to the District under the District’s
current As-Needed Utility Locating Services contract, which expires
on June 30, 2018. Staff found that AIRX’s performance under the
current contract has been exceptional with a 100% accuracy rate of
utility locations in support of the District’s USA Mark-out program.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer
The funds for this contract will be expended from the Fiscal Years
2018, 2019, and 2020 budgets for various CIP and developer projects
or programs. This contract is for professional As-Needed Utility
Locating Services based on the District's need and schedule, and
expenditures will not be made until a task order is approved by the
District for the consultant's services.
4
Based on a review of the financial budgets, the Project Manager
anticipates that the budgets will be sufficient to support the
professional as-needed consulting services required for the projects
or programs.
The Finance Department has determined that, under the current rate
model, the funds to cover this contract will be available as
budgeted for these projects or programs.
STRATEGIC GOAL:
This Project supports the District’s Mission statement, “To provide
high value water and wastewater services to the customers of the
Otay Water District in a professional, effective, and efficient
manner” and the District’s Vision, “A District that is at the
forefront in innovations to provide water services at affordable
rates, with a reputation for outstanding customer service.”
LEGAL IMPACT:
None.

SUBJECT: Approval of Water Supply Assessment and Verification Report
(November 2017) for the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors
(Board) approve the Water Supply Assessment Report and
Verification (WSA&V Report) dated November 2017 for the County
of San Diego Otay Ranch Village 14 and Planning Area 16/19
Project, as required by Senate Bills 610 and 221 (see Exhibit A
for Project location).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board approval of the November 2017 WSA&V Report for
the County of San Diego Otay Ranch Village 14 and Planning Area
16/19 Project, as required by Senate Bill 610 and Senate Bill
221 (SB 610 and SB 221).
ANALYSIS:
The County of San Diego submitted a request to the District for
a WSA&V Report, pursuant to SB 610 and SB 221. SB 610 and SB
221 require that, upon the request of the City or County, a
water purveyor, such as the District, prepare a water supply
assessment and verification report to be included in the
2
California Environmental Quality Act (CEQA) environmental
documentation. SB 610 requires a city or county to evaluate
whether water supplies will be sufficient to meet the projected
water demand for certain “projects” that are otherwise subject
to the requirement of the CEQA. SB 610 provides its own
definition of “project” in Water Code Section 10912.
SB 221 requires affirmative written verification from the water
purveyor of the public water system that sufficient water
supplies are planned to be available for certain residential
subdivisions of property. The requirements of SB 610 and SB 221
are addressed by the November 2017 WSA&V Report for this
Project. The WSA&V Report was prepared by the District in
consultation with Dexter Wilson Engineering, Inc., the San Diego
County Water Authority (Water Authority), and the County of San
Diego (County).
Prior to transmittal to the County, the WSA&V Report must be
approved by the Board of Directors. An additional explanation
of the intent of SB 610 and SB 221 is provided in Exhibit B, the
County of San Diego Otay Ranch Village 14 and Planning Area
16/19 WSA&V Report is provided as Exhibit C.
For the County of San Diego Otay Ranch Village 14 and Planning
Area 16/19 Project, the County is the responsible land use
agency that requested the SB 610 and SB 221 water supply
assessment and verification report from the District. The
request for the WSA&V Report, in compliance with SB 610 and SB
221 requirements, was made by the County because the Project
meets or exceeds one or both of the following SB 610 and SB 221
criteria:
A proposed residential development of more than 500
dwelling units.
A proposed commercial office building employing more than
1,000 persons or having more than 250,000 square feet of
floor space.
A mixed-use project that includes one or more of the land
uses specified in SB 610.
A project that would demand an amount of water equivalent
to, or greater than, the amount of water required by a 500
dwelling unit project.
3
The County of San Diego Otay Ranch Village 14 and Planning Area
16/19 Project is located within the Otay Ranch General
Development Plan along Proctor Valley Road, just east of the
City of Chula Vista. Village 14 is planned for 994 homes in
three distinct areas (referred to as the South, Central, and
North Village 14). The plan includes 878 single-family homes
located in gated enclaves and another 116 detached courtyard
homes. Twelve neighborhoods are planned with approximate
densities ranging from 0.2 to 10.0 dwelling units per acre.
Otay Ranch Village 14 is planned around a “Village Core,”
centrally located in the heart of the village and will include a
9.7-acre elementary school, a 7.2-acre Village Green (public
park), and a 1.7-acre Mixed Use Site with up to 10,000 square
feet of commercial/retail uses. There will also be a 2.3-acre
public safety site for a fire station and satellite sheriff’s
facility. Additional public and private parks, swim clubs,
trails, and recreational facilities will be situated throughout
South, Central, and North Village 14. Planning Area 19 is
planned for 13 one-acre estate lots and Planning Area 16 is
planned for 112 lots averaging 3 acres in size.
The expected potable water demand for the Otay Ranch Village 14
and Planning Areas 16/19 Project is 797,970 gallons per day
(GPD) or about 893.9 acre-feet per year (AFY). The number of
dwelling units and the areas for commercial development, parks,
schools, and public safety sites match the total approved units
noted on Table C of the District’s Water Facilities Master Plan
Update dated March 2016 (WFMP Update).
The entire watershed of the Otay Ranch Village 14 and Planning
Areas 16/19 Project is tributary to the Upper and Lower Otay
Reservoirs. The use of recycled water within watersheds
tributary to surface water storage reservoirs that provide
supply for potable domestic water uses must be approved by the
owners of the reservoirs in order to protect water quality in
these reservoirs. The Applicants for other projects within this
watershed have met with and discussed the use of recycled water
with the City of San Diego, the operator of the reservoirs. The
City of San Diego has requested all projects not use recycled
water because they are concerned about the runoff from the
project entering the reservoirs and increasing nutrients and
salinity. For this reason, the projected water use within the
Otay Ranch Village 14 and Planning Areas 16/19 Project has been
estimated with the assumption that the use of recycled water
within the project will not be allowed. However, prior to the
approval of a Sub-area master Plan for this project, the
4
Developer will need to pursue the use of recycled water with the
City of San Diego.
The request for compliance with SB 221 requirements was made by
the County because the Project will exceed the SB 221 criteria
of a proposed residential development with more than 500
dwelling units.
Pursuant to SB 610 and SB 221, the WSA&V Report incorporates by
reference the current Urban Water Management Plans and other
water resources planning documents of the District, the Water
Authority, and the Metropolitan Water District of Southern
California (Metropolitan). The District prepared the WSA&V
Report in consultation with Dexter Wilson Engineering, Inc., the
Water Authority, and the County, which demonstrates and
documents that sufficient water supplies are planned for and are
intended to be made available over a 20-year planning horizon
under normal supply conditions, in single and multiple-dry years
to meet the projected demand of the County of San Diego Otay
Ranch Village 14 and Planning Area 16/19 Project and other
planned development projects within the District.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer
The District has been reimbursed $8,000 for all costs associated
with the preparation of the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project WSA&V Report. The
reimbursement was accomplished via an $8,000 deposit the Project
proponents placed with the District.
STRATEGIC GOAL:
The preparation and approval of the WSA&V Report for the County
of San Diego Otay Ranch Village 14 and Planning Area 16/19
Project supports the District’s Mission statement, “To provide
high value water and wastewater services to the customers of the
Otay Water District in a professional, effective, and efficient
manner” and the General Manager’s Vision, “A District that is at
the forefront in innovations to provide water services at
affordable rates, with a reputation for outstanding customer
service.”
LEGAL IMPACT:
Approval of a WSA&V Report for the County of San Diego Otay
Ranch Village 14 and Planning Area 16/19 Project in form and
content satisfactory to the Board of Directors would allow the
5
District to comply with the requirements of Senate Bills 610 and
221.

Background Information
The Otay Water District (District) prepared the November 2017 Water Supply
Assessment and Verification (WSA&V) Report for the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project at the request of the County of San Diego
(County). The County’s WSA&V request letter dated November 28, 2017 was received
by the District on November 28, 2017 so the 90-day deadline for the District to provide
the Board an approved WSA&V Report to the County ends February 26, 2018.
The County of San Diego Otay Ranch Village 14 and Planning Area 16/19 Project is
located within the jurisdictions of the District, the San Diego County Water Authority
(Water Authority), and the Metropolitan Water District of Southern California (MWD).
See Exhibit A for Project location. To obtain permanent imported water supply service,
land areas are required to be within the jurisdictions of the District, Water Authority, and
MWD.
The November 2017 WSA&V Report for the County of San Diego Otay Ranch Village
14 and Planning Area 16/19 Project has been prepared by the District in consultation
with Dexter Wilson Engineering, Inc., the Water Authority, and the County, pursuant to
Public Resources Code Section 21151.9 and California Water Code Sections 10631,
10656, 10910, 10911, 10912, and 10915 referred to as Senate Bill (SB) 610 and
Government Code Sections 65867.5, 66455.3, and 66473.7 referred to as SB 221. SB
610 and SB 221 amended state law, effective January 1, 2002, intending to improve the
link between information on water supply availability and certain land use decisions
made by cities and counties. SB 610 requires that the water purveyor of the public
water system prepare a water supply assessment to be included in the California
Environmental Quality Act (CEQA) environmental documentation and approval process
of certain proposed projects. SB 221 requires affirmative written verification from the
water purveyor of the public water system that sufficient water supplies are to be
available for certain residential subdivision of property. The requirements of SB 610
and SB 221 are addressed in the November 2017 WSA&V Report for the County of San
Diego Otay Ranch Village 14 and Planning Area 16/19 Project. The expected potable
water demands for the County of San Diego Otay Ranch Village 14 and Planning Area
16/19 Project are 797,970 gallons per day (GPD) or about 893.9 acre-feet per year
(AFY).
Therefore, based on the findings from the Otay WD’s 2015 UWMP and the Water
Authority’s 2015 UWMP, this Project will result in no unanticipated demands.
The District currently depends on the Water Authority and the MWD for all of its potable
water supplies and regional water resource planning. The District’s 2015 Urban Water
Management Plan (UWMP) relies heavily on the UWMP’s and Integrated Water
Resources Plans (IRPs) of the Water Authority and MWD for documentation of supplies
available to meet projected demands. These plans are developed to manage the
2
uncertainties and variability of multiple supply sources and demands over the long-term
through preferred water resources strategy adoption and resource development target
approvals for implementation.
MWD, in January 2016, approved the update of their Integrated Water Resources Plan
(IRP). The 2015 IRP Update describes an adaptive management approach to mitigate
against future water supply uncertainty. The new uncertainties that are significantly
affecting California’s water resources include:
The State Water Project (SWP) supplies which are affected by a changing
climate and the operational constraints in the ecologically struggling Sacramento-
San Joaquin Delta.
Periodic extended drought conditions.
These uncertainties have rightly caused concern among Southern California water
supply agencies regarding the validity of the current water supply documentation.
MWD is currently involved in several proceedings concerning Delta operations to
evaluate and address environmental concerns. In addition, at the State level, the Delta
Vision and Bay-Delta Conservation Plan processes are defining long-term solutions for
the Delta.
The SWP represents approximately 9% of MWD’s 2025 Dry Resources Mix, with the
supply buffer included. A 22% cutback in SWP supply represents an overall 2% (22%
of 9% is 2%) cutback in MWD supplies in 2025. Neither the Water Authority nor MWD
has stated that there is insufficient water for future planning in Southern California.
Each agency is in the process of reassessing and reallocating their water resources.
Under preferential rights, MWD can allocate water without regard to historic water
purchases or dependence on MWD. Therefore, the Water Authority and its member
agencies are taking measures to reduce dependence on MWD through development of
additional supplies and a water supply portfolio that would not be jeopardized by a
preferential rights allocation.
As calculated by MWD, the Water Authority’s current preferential right is 18.27% of
MWD’s supply, while the Water Authority accounted for approximately 22% of MWD’s
total revenue. So MWD could theoretically cut back the Water Authority’s supply and
theoretically, the Water Authority should have alternative water supply sources to make
up for the difference. In the Water Authority’s 2010 UWMP, they had already planned to
reduce reliance on MWD supplies. This reduction is planned to be achieved through
diversification of their water supply portfolio.
The Water Authority’s Drought Management Plan (May 2006) provides the Water
Authority and its member agencies with a series of potential actions to engage when
faced with a shortage of imported water supplies due to prolonged drought conditions.
3
Such actions help avoid or minimize impacts of shortages and ensure an equitable
allocation of supplies throughout the San Diego County region.
The Otay Water District Board of Directors could acknowledge the ever-present
challenge of balancing water supply with demand and the inherent need to possess a
flexible and adaptable water supply implementation strategy that can be relied upon
during normal and dry weather conditions. The responsible regional water supply
agencies have and will continue to adapt their resource plans and strategies to meet
climatological, environmental, and legal challenges so that they may continue to provide
water supplies to their service areas. The regional water suppliers (i.e., the Water
Authority and MWD), along with the District, fully intend to maintain sufficient reliable
supplies through the 20-year planning horizon under normal, single, and multiple-dry
year conditions to meet projected demand of the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project, along with existing and other planned
development projects within the District’s service area.
If the regional water suppliers determine additional water supplies will be required, or in
this case, that water supply portfolios need to be reassessed and redistributed with the
intent to serve the existing and future water needs throughout Southern California, the
agencies must indicate the status or stage of development of actions identified in the
plans they provide. MWD’s 2015 IRP update will then cause the Water Authority to
update its IRP, which will then provide the District with the necessary water supply
documentation. Identification of a potential future action in such plans does not by itself
indicate that a decision to approve or to proceed with the action has been made. The
District’s Board approval of the Approval of Water Supply Assessment and Verification
Report (November 2017) for the County of San Diego Otay Ranch Village 14 and
Planning Area 16/19 Project WSA&V Report does not in any way guarantee water
supply to the Project.
Alternatively, if the WSA&V Report is written to state that water supply is or will be
unavailable; the District must include, in the assessment, a plan to acquire additional
water supplies. At this time, the District should not state there is insufficient water
supply.
At the present time, based on the information available, the District is able to clearly
describe the current water supply situation clearly, indicating intent to provide supply
through reassessment and reallocation by the regional, as well as, the local water
suppliers. In doing so, it is believed that the Board has met the intent of the SB 610
statute, that the land use agencies and the water agencies are coordinating their efforts
in planning water supplies for new development.
With District Board approval of the County of San Diego Otay Ranch Village 14 and
Planning Area 16/19 Project WSA&V Report, the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project proponents can proceed with the draft
environmental documentation required for the CEQA review process. The water supply
4
issues will be addressed in these environmental documents, consistent with the
WSA&V Report.
The District, as well as others, can comment on the draft EIR with recommendations
that water conservation measures and actions be employed on the County of San Diego
Otay Ranch Village 14 and Planning Area 16/19 Project.
Some recent actions regarding water supply assessments and verification reports by
Otay Water District are as follows:
The Board approved the water supply assessment report for the Otay Ranch
University Villages Project on November 6, 2013.
The Board approved the water supply assessment report for the Otay Ranch
Resort Village Project on May 7, 2014.
The Board approved the water supply assessment report for the Otay Ranch
Planning Area 12 Freeway Commercial Project on April 1, 2015.
The Board approved the water supply assessment report for the Otay 250
Sunroad East Otay Mesa Business Park Specific Plan Amendment Project on
July 6, 2016.
The Board approved the water supply assessment report for the City of Chula
Vista University Innovation District Project on October 5, 2016.
Water supplies necessary to serve the demands of the proposed County of San Diego
Otay Ranch Village 14 and Planning Area 16/19 Project, along with existing and other
projected future users, as well as the actions necessary to develop these supplies, have
been identified in the water supply planning documents of the District, the Water
Authority, and MWD.
The WSA&V Report includes, among other information, an identification of existing
water supply entitlements, water rights, water service contracts, or agreements relevant
to the identified water supply needs for the proposed County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project. The WSA&V Report demonstrates and
documents that sufficient water supplies are planned and are intended to be available
over a 20-year planning horizon, under normal conditions and in single and multiple-dry
years, to meet the projected demand of the proposed and the existing and other
planned development projects within the District.
Accordingly, after approval of a WSA&V Report for the County of San Diego Otay
Ranch Village 14 and Planning Area 16/19 Project by the District's Board of Directors,
the WSA&V Report may be used to comply with the requirements of the legislation
enacted by Senate Bills 610 and 221 as follows:
5
Senate Bill (SB) 610 Water Supply Assessment: The District's Board of Directors
approved WSA&V Report may be incorporated into the California Environmental
Quality Act (CEQA) compliance process for the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project as a water supply assessment report
consistent with the requirements of the legislation enacted by SB 610. The County
of San Diego, as lead agency under the CEQA for the County of San Diego Otay
Ranch Village 14 and Planning Area 16/19 Project environmental documentation,
may cite the approved WSA&V Report as evidence that a sufficient water supply is
planned and intended to be available to serve the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project.
Senate Bill (SB) 221 Water Supply Verification: The District's Board of Directors
approved WSA&V Report may be incorporated into the County of San Diego Otay
Ranch Village 14 and Planning Area 16/19 Project as a water supply verification
report, consistent with the requirements of the legislation enacted by SB 221. The
County, within their process of approving the County of San Diego Otay Ranch
Village 14 and Planning Area 16/19 Project, may cite the approved WSA&V Report
as verification of intended sufficient water supply to serve the Project.

Water Supply Assessment and Verification Report
November 2017
Otay Ranch Village 14 and Planning Areas 16/19 Project
Executive Summary
The Otay Water District (Otay WD) prepared this Water Supply Assessment and Verification
Report (WSA&V Report) at the request of the County of San Diego (County) for the Otay
Ranch Village 14 and Planning Areas 16/19 Project. The County is having an environmental
impact report (EIR) prepared for the development of this project. Jackson Pendo
Development Company is the project applicant.
Otay Ranch Village 14 and Planning Areas 16/19 Project Overview and Water Use
The Otay Ranch Village 14 and Planning Areas 16/19 Project is located within the
jurisdictions of the Otay WD, the San Diego County Water Authority (Water Authority), and
the Metropolitan Water District of Southern California (MWD). In order to obtain permanent
imported water supply service, land areas are required to be within the jurisdictions of the
Otay WD, Water Authority, and MWD.
The proposed project entitlement includes a Specific Plan entitled “Otay Ranch Village 14
and Planning Areas 16/19 Specific Plan”, General Plan Amendments, EIR, Rezone, Tentative
Map, and an Otay Ranch Resource Management Plan Amendment. The County is having an
EIR prepared for development of the 1,283.6 acre site (Otay Ranch Village 14 and Planning
Areas 16/19 Project). The land use plan proposes a transitional village between the City of
Chula Vista and community of Jamul with up to 1,119 residential units. The project is located
within the Otay Ranch General Development Plan along Proctor Valley Road, just east of the
City of Chula Vista.
Village 14 is planned for 994 homes in three distinct areas (referred to as the South, Central
and North Village 14) with 878 single-family homes located in gated enclaves and 116 will be
detached courtyard homes. Twelve neighborhoods are planned with approximate densities
ranging from 0.2 to 10.0 dwelling units per acre. Otay Ranch Village 14 is planned around a
“Village Core”, centrally located in the heart of the village and will include a 9.7-acre
elementary school; a 7.2-acre Village Green (public park); a 1.7-acre Mixed Use Site with up
to 10,000 square feet of commercial/retail uses; and a 2.3-acre public safety site for a fire
station and satellite sheriff’s facility. Additional public and private parks, swim clubs, trails
and recreational facilities will be situated throughout South, Central and North Village 14.

Planning Area 19 is planned for 13 one-acre estate lots and Planning Area 16 is planned for
112 lots averaging 3 acres in size.
The expected potable water demand for the Otay Ranch Village 14 and Planning Areas 16/19
Project is 797,970 gallons per day (gpd) or about 893.9 acre feet per year (AFY). The number
of dwelling units and the areas for commercial development, parks, schools and public safety
sites match the total approved units noted on Table C of the District’s -Water Facilities Master
Plan Update dated March 2016 (WFMP Update).
The entire watershed of the Otay Ranch Village 14 and Planning Areas 16/19 Project is
tributary to the Upper and Lower Otay Reservoirs. The use of recycled water within
watersheds tributary to surface water storage reservoirs that provide supply for potable
domestic water uses must be approved by the owners of the reservoirs in order to protect
water quality in these reservoirs. The Applicants for other projects within this watershed have
met with and discussed the use of recycled water with the City of San Diego, the operator of
the reservoirs. The City of San Diego has requested all projects not use recycled water
because they are concerned about the runoff from the project entering the reservoirs and
increasing nutrients and salinity. For this reason, the projected water use within the Otay
Ranch Village 14 and Planning Areas 16/19 Project has been estimated with the assumption
that the use of recycled water within the project will not be allowed.
Planned Imported Water Supplies from the Water Authority and MWD
The Water Authority and MWD have an established process that ensures supplies are being
planned to meet future growth. Any annexations and revisions to established land use plans
are captured in the San Diego Association of Governments (SANDAG) updated forecasts for
land use planning, demographics, and economic projections. SANDAG serves as the
regional, intergovernmental planning agency that develops and provides forecast information.
The Water Authority and MWD update their demand forecasts and supply needs based on the
most recent SANDAG forecast approximately every five years to coincide with preparation of
their UWMP’s. Prior to the next forecast update, local jurisdictions with land use authority
may require water supply assessment and/or verification reports for proposed land
developments that are not within the OTAY WD, Water Authority, or MWD jurisdictions (i.e.
pending or proposed annexations) or that have revised land use plans with either lower or
higher development intensities than reflected in the existing growth forecasts. Proposed land
areas with pending or proposed annexations, or revised land use plans, typically result in
creating higher demand and supply requirements than previously anticipated. The Otay WD,
Water Authority, and MWD next demand forecast and supply requirements and associated
planning documents would then capture any increase or decrease in demands and required
supplies as a result of annexations or revised land use planning decisions.
An important planning document utilized by MWD, the Water Authority and Otay WD is the
Integrated Resources Plan (IRP) which describes an agency’s long term water plan. MWD’s
Otay Water District
Water Supply Assessment and Verification Report

2015 IRP offers an adaptive management strategy to protect the region from future supply
shortages. This adaptive management strategy has five components: achieve additional
conservation savings, develop additional local water supplies, maintain Colorado River
Aqueduct supplies, stabilize State Water Project supplies, and maximize the effectiveness of
storage and transfer. MWD’s 2015 IRP has a plan for identifying and implementing
additional resources that expand the ability for MWD to meet future changes and challenges
as necessary to ensure future reliability of supplies. The proper management of these
resources help to ensure that the southern California region, including San Diego County, will
have adequate water supplies to meet long-term future demands.
Another important planning document is the UWMP. The California Urban Water
Management Planning Act (Act), which is included in the California Water Code, requires all
urban water suppliers within the state to prepare an UWMP and update it every five years.
The purpose and importance of the UWMP has evolved since it was first required 25 years
ago. State agencies and the public frequently use the document to determine if agencies are
planning adequately to reliably meet future demands. As such, UWMPs serve as an important
element in documenting supply availability for the purpose of compliance with state laws,
Senate Bills 610 and 221, linking water supply sufficiency to large land-use development
approval. Agencies must also have a UWMP prepared, pursuant to the Act, in order to be
eligible for state funding and drought assistance.
MWD’s 2015 UWMP Findings state that MWD has supply capabilities that would be
sufficient to meet expected demands from 2020 through 2040. MWD has plans for supply
implementation and continued development of a diversified resource mix including programs
in the Colorado River Aqueduct, State Water Project, Central Valley Transfers, local resource
projects, and in-region storage that enables the region to meet its water supply needs.
The County Water Authority Act, Section 5 subdivision 11, states that the Water Authority
“as far as practicable, shall provide each of its member agencies with adequate supplies of
water to meet their expanding and increasing needs.”
As part of preparation of a written water supply assessment report, an agency’s shortage
contingency analysis should be considered in determining sufficiency of supply. Section 11
of the Water Authority’s 2015 UWMP Update contain a detailed shortage contingency
analysis that addresses a regional catastrophic shortage situation and drought management.
The analysis demonstrates that the Water Authority and its member agencies, through the
Integrated Contingency Plan, Emergency Storage Project, and Water Shortage and Drought
Response Plan are taking actions to prepare for and appropriately handle an interruption of
water supplies. The Water Shortage and Drought Response Plan, provides the Water
Authority and its member agencies with a series of potential actions to take when faced with a
shortage of imported water supplies from MWD due to prolonged drought or other supply
shortfall conditions. The actions will help the region avoid or minimize the impacts of
shortages and ensure an equitable allocation of supplies.

Water supply agencies throughout California continue to face climate, environmental, legal,
and other challenges that impact water source supply conditions, such as the court rulings
regarding the Sacramento-San Joaquin Delta issues and reoccurring droughts impacting the
western states. Even with these ever present challenges, the Water Authority and MWD,
along with Otay WD fully intend to have sufficient, reliable supplies to serve demands.
Otay Water District Water Supply Development Program
In evaluating the availability of sufficient water supply, the Otay Ranch Village 14 and
Planning Areas 16/19 Project will be required to participate in the water supply development
program being implemented by the Otay WD. This is intended to be achieved through
financial participation in several local and/or regional water supply development projects
envisioned by the Otay WD. These water supply projects are in addition to those identified as
sustainable supplies in the current Water Authority and MWD UWMP, IRP, Master Plans,
and other planning documents, and are in response to the regional water supply issues. These
new water supply projects are not currently developed and are in various stages of the
planning process. Imported water supplies along with the development of these additional
Otay WD water supply development projects supplies are intended to increase water supplies
to serve the Otay Ranch Village 14 and Planning Areas 16/19 Project water supply needs and
that of other similar development projects. The Otay WD water supply development program
includes but is not limited to projects such as the Middle Sweetwater River Basin
Groundwater Well project, the Rancho del Rey Groundwater Well project, the North District
Recycled Water Supply Concept, and the Rosarito Ocean Desalination Facility project. The
Water Authority and MWD’s next forecasts and supply planning documents would capture
any increase in water supplies resulting from any new water resources developed by the Otay
WD.
Findings
The WSA&V Report identifies and describes the processes by which water demand
projections for the proposed Otay Ranch Village 14 and Planning Areas 16/19 project will be
fully included in the water demand and supply forecasts of the Urban Water Management
Plans and other water resources planning documents of the Water Authority and MWD.
Water supplies necessary to serve the demands of the proposed project, along with existing
and other projected future users, as well as the actions necessary and status to develop these
supplies, have been identified in the Otay Ranch Village 14 and Planning Areas 16/19 project
WSA&V Report and will be included in the future water supply planning documents of the
Water Authority and MWD.
This WSA&V Report includes, among other information, an identification of existing water
supply entitlements, water rights, water service contracts, water supply projects, or
agreements relevant to the identified water supply needs for the proposed Otay Ranch Village

14 and Planning Areas 16/19 project. The WSA&V Report demonstrates and documents 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 and multiple dry years to meet the
projected demand of the proposed Otay Ranch Village 14 and Planning Areas 16/19 project
and the existing and other planned development projects to be served by the Otay WD.
Accordingly, after approval of a WSA&V Report for the Otay Ranch Village 14 and Planning
Areas 16/19 project by the Otay WD Board of Directors (Board), the WSA&V Report may be
used to comply with the requirements of the legislation enacted by Senate Bills 610 and 221
as follows:
1. Senate Bill 610 Water Supply Assessment: The Otay WD Board approved WSA&V
Report may be incorporated into the California Environmental Quality Act (CEQA)
Environmental Impact Report (EIR) compliance process for the Otay Ranch Village
14 and Planning Areas 16/19 project as a water supply assessment report consistent
with the requirements of the legislation enacted by SB 610. The County, as lead
agency under CEQA for the Otay Ranch Village 14 and Planning Areas 16/19 project
EIR and Alternatives, may cite the approved WSA&V Report as evidence that a
sufficient water supply is planned for and is intended to be made available to serve the
Otay Ranch Village 14 and Planning Areas 16/19 project.
2. Senate Bill 221 Water Supply Verification: The Otay WD Board approved WSA&V
Report may be incorporated into the County’s Tentative Map approval process for the
Otay Ranch Village 14 and Planning Areas 16/19 project as a water supply
verification report, consistent with the requirements of the legislation enacted by SB
221. The County, within their process of approving the Otay Ranch Village 14 and
Planning Areas 16/19 project’s Tentative Map, may cite the approved WSA&V
Report as verification of intended sufficient water supply to serve the Otay Ranch
Village 14 and Planning Areas 16/19 project.
Section 1 - Purpose
The County of San Diego is having an environmental impact report (EIR) prepared for the
development of the 1283.6 acre project (Otay Ranch Village 14 and Planning Areas 16/19
Project). The project is located within the Otay Ranch General Development Plan along
Proctor Valley Road between the City of Chula Vista and the community of Jamul. The
County requested that the Otay WD prepare a Water Supply Assessment and Verification
(WSA&V) Report for the Otay Ranch Village 14 and Planning Areas 16/19 Project. The
Otay Ranch Village 14 and Planning Areas 16/19 Project description is provided in Section 3
of this WSA&V Report.

This WSA&V Report for the Otay Ranch Village 14 and Planning Areas 16/19 project has
been prepared by the Otay WD in consultation with Dexter Wilson Engineering, Inc., the
Water Authority, and the County pursuant to Public Resources Code Section 21151.9 and
California Water Code Sections 10631, 10656, 10910, 10911, 10912, and 10915 referred to as
Senate Bill (SB) 610 and Business and Professions Code Section 11010 and Government
Code Sections 65867.5, 66455.3, and 66473.7 referred to as SB 221. SB 610 and SB 221
amended state law, effective January 1, 2002, is intended to improve the link between the
information on water supply availability and certain land use decisions made by cities and
counties. SB 610 requires that the water purveyor of the public water system prepare a water
supply assessment to be included in the CEQA documentation and approval process of certain
proposed projects. SB 221 requires affirmative written verification from the water purveyor
of the public water system that sufficient water supplies are to be available for certain
residential subdivisions of property prior to approval of a tentative map. The requirements of
SB 610 and SB 221 are being addressed by this WSA&V Report.
The County also requested, since the requirements of SB 610 and SB 221 are substantially
similar, that Otay WD prepare both the water supply assessment and verification
concurrently.
This WSA&V Report evaluates water supplies that are planned to be available during normal,
single dry year, and multiple dry water years during a 20-year planning horizon to meet
existing demands, expected demands of the Otay Ranch Village 14 and Planning Areas 16/19
Project, and reasonably foreseeable planned future water demands to be served by Otay WD.
The Otay Water District Board of Directors approved WSA&V Report is planned to be used
by the County in its evaluation of the Otay Ranch Village 14 and Planning Areas 16/19
Project under the CEQA approval process procedures.
Section 2 - Findings
The Otay WD prepared this WSA&V Report at the request of the County for the Otay Ranch
Village 14 and Planning Areas 16/19 Project. Jackson Pendo Development Company
submitted an entitlement application to the County for the project.
The Otay Ranch Village 14 and Planning Areas 16/19 Project is located within the
jurisdictions of the Otay WD, the Water Authority, and MWD. To obtain permanent
imported water supply service, land areas are required to be within the jurisdictions of the
Otay WD, Water Authority, and MWD to utilize imported water supply.
The expected potable water demand for the Otay Ranch Village 14 and Planning Areas 16/19
Project is 797,970 gallons per day (gpd) or about 893.9 acre feet per year (AFY). The number
of dwelling units and the areas for commercial development, parks, schools and public safety
sites match the total approved units noted on Table C of the District’s Water Facilities Master
Otay Water District

Plan Update dated March 2016 (WFMP Update). Recycled water is not proposed to be used
on the project due to its proximity to Upper Otay Reservoir.
The Water Authority and MWD have an established process that ensures supplies are being
planned to meet future growth. Any annexations and revisions to established land use plans
are captured in the San Diego Association of Governments (SANDAG) updated forecasts for
land use planning, demographics, and economic projections. SANDAG serves as the
regional, intergovernmental planning agency that develops and provides forecast information.
The Water Authority and MWD update their demand forecasts and supply needs based on the
most recent SANDAG forecast approximately every five years to coincide with preparation of
their urban water management plans. Prior to the next forecast update, local jurisdictions may
require water supply assessment and/or verification reports for proposed land developments
that are not within the Otay WD, Water Authority, or MWD jurisdictions (i.e. pending or
proposed annexations) or that have revised land use plans with lower or higher land use
intensities than reflected in the existing growth forecasts. Proposed land areas with pending
or proposed annexations, or revised land use plans, typically result in creating higher demand
and supply requirements than anticipated. The Otay WD, the Water Authority, and MWD
next demand forecast and supply requirements and associated planning documents would then
capture any increase or decrease in demands and required supplies as a result of annexations
or revised land use planning decisions.
This process is utilized by the Water Authority and MWD to document the water supplies
necessary to serve the demands of the Otay Ranch Village 14 and Planning Areas 16/19
project, along with existing and other projected future users, as well as the actions necessary
to develop any required water supplies. Through this process the necessary demand and
supply information is thus assured to be identified and incorporated within the water supply
planning documents of the Water Authority and MWD.
This WSA&V Report includes, among other information, an identification of existing water
supply entitlements, water rights, water service contracts, proposed water supply projects, and
agreements relevant to the identified water supply needs for the proposed Otay Ranch Village
14 and Planning Areas 16/19 Project. This WSA&V Report incorporates by reference the
current Urban Water Management Plans and other water resources planning documents of the
Otay WD, the Water Authority, and MWD. The Otay WD prepared this WSA&V Report to
assess and document that sufficient water supplies are planned for and are intended to be
acquired to meet projected water demands of the Otay Ranch Village 14 and Planning Areas
16/19 Project as well as existing and other reasonably foreseeable planned development
projects within the Otay WD for a 20-year planning horizon, in normal supply years and in
single dry and multiple dry years.
The Otay Water District 2015 UWMP includes a water conservation component to comply
with Senate Bill 7 of the Seventh Extraordinary Session (SBX 7-7), which became effective
February 3, 2010. This new law was the water conservation component to the Delta
legislation package, and seeks to achieve a 20 percent statewide reduction in urban per capita
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
8
water use in California by December 31, 2020. Specifically, SBX 7-7 from this Extraordinary
Session requires each urban retail water supplier to develop urban water use targets to help
meet the 20 percent reduction goal by 2020 (20x2020), and an interim water reduction target
by 2015.
Otay WD adopted Method 1 to set its 2015 interim and 2020 water use targets. Method 1
requires setting the 2020 water use target to 80 percent of baseline per capita water use target
as provided in the State’s 20x2020 Water Conservation Plan. The Otay WD 2015 target was
172 gpcd which it met (2015 actual was 124 gpcd) and the 2020 gpcd target (80 percent of
baseline) is 153 gpcd. The Otay WD’s recent per capita water use has been declining and
current water use already meets the 2020 target as calculated using Method 1. This recent
decline in per capita water use is largely due to drought water use restrictions, increased water
costs, and economic conditions. However, Otay WD’s effective water use awareness
campaign and enhanced conservation mentality of its customers will likely result in some
long-term carryover of these reduced consumption rates.
Based on a normal water supply year, the five-year increments for a 20-year projection
indicate projected potable and recycled water supply is being planned for and is intended to be
acquired to meet the estimated water demand targets of the Otay WD (42,720 acre-feet (ac-ft)
in 2020 to 57,582 ac-ft in 2040) per the Otay Water District 2015 UWMP. Based on dry year
forecasts, the estimated water supply is also being planned for and is intended to be acquired
to meet the projected water demand, during single dry and multiple dry year scenarios. On
average, the dry-year demands are about 6.64 percent higher than the normal year demands.
The Otay WD recycled water supply is assumed to be drought-proof and not subject to
reduction during dry periods.
Together, these findings assess, demonstrate, and document that sufficient water supplies are
planned for and are intended to be acquired for the Otay Ranch Village 14 and Planning Areas
16/19 Project. In addition, the actions necessary to develop these supplies are and will be
further documented, to serve the proposed project and the existing and other reasonably
foreseeable planned development projects within the Otay WD in both normal and single and
multiple dry year forecasts for a 20-year planning horizon.
Section 3 - Project Description

The Otay Ranch Village 14 and Planning Areas 16/19 Project is planned to include up to 994
residential homes in the Village 14 core area that includes a school, public use facility, mixed
use commercial site, parks, and open space. An additional 125 lower density residential units
are proposed in Planning Areas 16/19 for a total of up to 1,119 residential units. Refer to
Appendix B for the proposed development plan of the Otay Ranch Village 14 and Planning
Areas 16/19 project. The EIR proposes a land exchange alternative for the project that would
designate Planning Areas 16/19 as open space and allow for the development of up to 1,530
residential units in Village 14. This land use alternative includes lands within Village 14 and
Planning Area 16 that are owned by the State of California. The State of California is
considering, but has not approved, the land exchange alternative.
The County has discretionary authority on land use decisions for the Otay Ranch Village 14
and Planning Areas 16/19 Project and can establish actions and/or permit approval
requirements. The projected potable water demands associated with the Otay Ranch Village
14 and Planning Areas 16/19 Project EIR has considered the anticipated County discretionary
actions and/or permit approvals and are incorporated into and used in this WSA&V Report.
The water demands for the proposed Otay Ranch Village 14 and Planning Areas 16/19 Project
are included in the projected water demand estimates provided in Section 5 – Historical and
Projected Water Demands.
Section 4 – Otay Water District
The Otay WD is a municipal water district formed in 1956 pursuant to the Municipal Water
District Act of 1911 (Water Code §§ 71000 et seq.). The Otay WD joined the Water
Authority as a member agency in 1956 to acquire the right to purchase and distribute imported
water throughout its service area. The Water Authority is an agency responsible for the
wholesale supply of water to its 24 public agency members in San Diego County.
The Otay WD currently meets all its potable demands with imported treated water from the
Water Authority. The Water Authority is the agency responsible for the supply of imported
water into San Diego County through its membership in MWD. The Water Authority
currently obtains about 40% of its imported supply from MWD, but is in the process of
further diversifying its available supplies.
The Otay WD provides water service to residential, commercial, industrial, and agricultural
customers, and for environmental and fire protection uses. In addition to providing water
throughout its service area, Otay WD also provides sewage collection and treatment services
to a portion of its service area known as the Jamacha Basin. The Otay WD also owns and
operates the Ralph W. Chapman Water Reclamation Facility (RWCWRF) which has an
Otay Water District

effective treatment capacity of 1.2 million gallons per day (mgd) or about 1,300 acre feet per
year to produce recycled water. On May 18, 2007, an additional source of recycled water
supply of up to 6 mgd, or about 6,720 acre feet per year, became available to Otay WD from
the City of San Diego’s South Bay Water Reclamation Plant (SBWRP).
The Otay WD jurisdictional area is generally located within the south central portion of San
Diego County and includes approximately 125 square miles. The Otay WD serves portions of
the unincorporated communities of southern El Cajon, La Mesa, Rancho San Diego, Jamul,
Spring Valley, Bonita, and Otay Mesa, the eastern portion of the City of Chula Vista and a
portion of the City of San Diego on Otay Mesa. The Otay WD jurisdiction boundaries are
roughly bounded on the north by the Padre Dam Municipal Water District, on the northwest
by the Helix Water District, and on the west by the South Bay Irrigation District (Sweetwater
Authority) and the City of San Diego. The southern boundary of Otay WD is the international
border with Mexico.
The planning area addressed in the Otay WD WFMP Update and the Otay WD 2015 UWMP
includes both the land within the jurisdictional boundary of the Otay WD and those areas
outside of the present Otay WD boundaries considered to be in the Area of Influence of the
Otay WD. Figure 3-1 contained within the Otay WD 2015 UWMP shows the jurisdictional
boundary of the Otay WD and the Area of Influence. The planning area is approximately 143
square miles, of which approximately 125 square miles are within the Otay WD current
boundaries and approximately 18 square miles are in the Area of Influence. The area east of
Otay WD is rural and currently not within any water purveyor jurisdiction and potentially
could be served by the Otay WD in the future if the need for imported water becomes
necessary, as is the case for the Area of Influence.
The City of Chula Vista, the City of San Diego, and the County of San Diego are the three
land use planning agencies within the Otay WD jurisdiction. Data on forecasts for land use
planning, demographics, economic projections, population, and the future rate of growth
within Otay WD were obtained from the San Diego Association of Governments (SANDAG).
SANDAG serves as the regional, intergovernmental planning agency that develops and
provides forecast information through the year 2050. Population growth within the Otay WD
service area is expected to increase from the 2015 figure of 217,339 to an estimated 285,340
by 2040. Land use information used to develop water demand projections are based upon
Specific or Sectional Planning Areas, the Otay Ranch General Development Plan/Sub-
regional Plan, East Otay Mesa Specific Plan Area, San Diego County Community Plans, and
City of San Diego, City of Chula Vista, and County of San Diego General Plans.
The Otay WD long-term historic growth rate has been approximately 4 percent. The growth
rate has significantly slowed due to the current economic conditions and it is expected to slow
as the inventory of developable land is diminished.
Climatic conditions within the Otay WD service area are characteristically Mediterranean
near the coast, with mild temperatures year round. Inland areas are both hotter in summer and
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
11
cooler in winter, with summer temperatures often exceeding 90 degrees and winter
temperatures occasionally dipping to below freezing. Most of the region’s rainfall occurs
during the months of December through March. Average annual rainfall is approximately
10.08 inches per year.
Historic climate data were obtained from the Western Regional Climate Center for Station
042706 (El Cajon). This station was selected because its annual temperature variation is
representative of most of the Otay WD service area. While there is a station in the City of
Chula Vista, the temperature variation at the City of Chula Vista station is more typical of a
coastal environment than the conditions in most of the Otay WD service area.
Urban Water Management Plan
In accordance with the California Urban Water Management Planning Act and recent
legislation, the Otay WD Board of Directors adopted an UWMP in June 2016 and
subsequently submitted the plan to the California Department of Water Resources (DWR).
As required by law, the Otay Water District 2015 UWMP includes projected water supplies
required to meet future demands through 2040. In accordance with Water Code Section
10910 (c)(2) and Government Code Section 66473.7 (c)(3), information from the Otay WD
2015 UWMP along with supplemental information from the Otay WD WFMP Update have
been utilized to prepare this WSA Report and are incorporated herein by reference.
The state Legislature passed Senate Bill 7 as part of the Seventh Extraordinary Session (SBX
7-7) on November 10, 2009, which became effective February 3, 2010. This new law was the
water conservation component to the Delta legislation package and seeks to achieve a 20
percent statewide reduction in urban per capita water use in California by December 31, 2020.
Specifically, SBX 7-7 from this Extraordinary Session requires each urban retail water
supplier to develop urban water use targets to help meet the 20 percent reduction goal by 2020
(20x2020), and an interim water reduction target by 2015.
The SBX 7-7 target setting process includes the following: (1) baseline daily per capita water
use; (2) urban water use target; (3) interim water use target; (4) compliance daily per capita
water use, including technical bases and supporting data for those determinations. In order
for an agency to meet its 2020 water use target, each agency can increase its use of recycled
water to offset potable water use and also step up its water conservation measures. The
required water use targets for 2020 and an interim target for 2015 are determined using one of
four target methods – each method has numerous methodologies.
In 2015, urban retail water suppliers were required to report interim compliance followed by
actual compliance in 2020. Interim compliance is halfway between the baseline water use and
2020 target. Baseline, target, and compliance-year water use estimates are required to be
reported in gallons per capita per day (gpcd).

Failure to meet adopted targets will result in the ineligibility of a water supplier to receive
grants or loans administered by the State unless one (1) of two (2) exceptions is met.
Exception one (1) states a water supplier may be eligible if they have submitted a schedule,
financing plan, and budget to DWR for approval to achieve the per capita water use
reductions. Exception two (2) states a water supplier may be eligible if an entire water service
area qualifies as a disadvantaged community.
Otay WD adopted Method 1 to set its 2015 interim and 2020 water use targets. Method 1
requires setting the 2020 water use target to 80 percent of baseline per capita water use target
as provided in the State’s 20x2020 Water Conservation Plan. The Otay WD was well below
its required 2015 target of 172 gpcd, with an actual 2015 gpcd of 124. The 2020 gpcd target
which is 80 percent of baseline is 153 gpcd.
The Otay WD’s recent per capita water use has been declining to the point where current
water use already meets the 2020 target for Method 1. This recent decline in per capita water
use is largely due to drought water use restrictions, increased water costs, and poor economic
conditions. However, Otay WD’s effective water use awareness campaign and enhanced
conservation mentality of its customers will likely result in some long-term carryover of these
reduced consumption rates beyond the current drought period.
Section 5 – Historical and Projected Water Demands
The projected demands for Otay WD are based on Specific or Sectional Planning Areas, the
Otay Ranch General Development Plan/Sub-regional Plan, the East Otay Mesa Specific Plan
Area, San Diego County Community Plans, and City of San Diego, City of Chula Vista, and
County of San Diego General Plans. This land use information is also used by SANDAG as
the basis for its most recent forecast data. This land use information was utilized for the
preparation of the Otay Water District WFMP Update and Otay Water District 2015 UWMP
to develop the forecasted demands and supply requirements.
In 1994, the Water Authority selected the Institute for Water Resources-Municipal and
Industrial Needs (MAIN) computer model to forecast municipal and industrial water use for
the San Diego region. The MAIN model uses demographic and economic data to project
sector-level water demands (i.e. residential and non-residential demands). This econometric
model has over a quarter of a century of practical application and is used by many cities and
water agencies throughout the United States. The Water Authority’s version of the MAIN
model was modified to reflect the San Diego region’s unique parameters and is known as
CWA-MAIN.
The foundation of the water demand forecast is the underlying demographic and economic
projections. This was a primary reason why, in 1992, the Water Authority and SANDAG
entered into a Memorandum of Agreement (MOA) in which the Water Authority agreed to
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
13
use the SANDAG current regional growth forecast for water supply planning purposes. In
addition, the MOA recognizes that water supply reliability must be a component of San Diego
County’s regional growth management strategy required by Proposition C, as passed by the
San Diego County voters in 1988. The MOA ensures a strong linkage between local general
plan land use forecasts and water demand projections and resulting supply needs for the San
Diego region.
Consistent with the previous CWA-MAIN modeling efforts, on October 15, 2013, the
SANDAG Board of Directors accepted the Series 13: 2050 Regional Growth Forecast. The
2050 Regional Growth Forecast will be used by SANDAG as the foundation for the next
Regional Comprehensive Plan update. SANDAG forecasts were used by local governments
for planning, including the Water Authority 2015 UWMP update.
The municipal and industrial forecast also included an updated accounting of projected
conservation savings based on projected regional implementation of the California Urban
Water Conservation Council (CUWCC) Best Management Practices and SANDAG
demographic information for the period 2015 through 2050. These savings estimates were
then factored into the baseline municipal and industrial demand forecast.
Agricultural demand projections were developed through a cooperative effort between Water
Authority staff, Water Authority member agencies, SANDAG, County of San Diego
Agricultural Weights and Measures, and the California Avocado Commission. Forecast driver
variables include irrigated acreage within the Water Authority’s service area, estimated crop
type distribution, and calculated historic water-use factors. SANDAG’s projection of
agricultural land conversions to other land use categories provides the long-term trend in
acreage used to forecast agricultural water use. The total agricultural forecast is then separated
into two categories: (1) projected demands in the Water Authority’s Transitional Special
Agricultural Water Rate (TSAWR) program and (2) demands under the Water Authority M&I
rate or agricultural demands met through local supplies.
The Water Authority and MWD update their water demand and supply projections within
their jurisdictions utilizing the SANDAG most recent growth forecast to project future water
demands. This provides for the important strong link between demand and supply projections
to the land use plans of the cities and the county. This provides for consistency between the
retail and wholesale agencies water demand projections, thereby ensuring that adequate
supplies are and will be planned for the Otay WD existing and future water users. Existing
land use plans, any revisions to land use plans, and annexations are captured in the SANDAG
updated forecasts. The Water Authority and MWD update their demand forecasts based on
the SANDAG most recent forecast approximately every five years to coincide with
preparation of their urban water management plans. Prior to the next forecast update, local
jurisdictions may require water supply assessment and/or verification reports consistent with
Senate Bills 610 and 221 for proposed land use developments that either have pending or
proposed annexations into the Otay WD, Water Authority, and MWD or that have revised
land use plans than originally anticipated. The Water Authority and MWD’s next forecasts
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
14
and supply planning documents would then capture any increase or decrease in demands
caused by annexations or revised land use plans.
In evaluating the availability of sufficient water supply, the Otay Ranch Village 14 and
Planning Areas 16/19 Project proponents are required to participate in the development of
alternative water supply project(s). This can be achieved through payment of the New Water
Supply Fee adopted by the Otay WD Board in May 2010. These water supply projects are in
addition to those identified as sustainable supplies in the current Water Authority and MWD
UWMP, IRP, Master Plans, and other planning documents. These new water supply projects
are in response to the regional water supply issues related to the Sacramento-San Joaquin
Delta and the current ongoing western states drought conditions. These additional water
supply projects are not currently developed and are in various stages of the planning process.
A few examples of these alternative water supply projects include the Middle Sweetwater
River Basin Groundwater Well project, the Otay WD Desalination project, and the Rancho
del Rey Groundwater Well project. The Water Authority and MWD next forecast and supply
planning documents would capture any increase in water supplies resulting from verifiable
new water resources developed by the Otay WD.
In addition, MWD’s 2015 UWMP identified potential reserve supplies in the supply
capability analysis (Tables 2-4, 2-5, and 2-6), which could be available to meet any
unanticipated demands. The Water Authority and MWD’s next forecasts and supply planning
documents would capture any increase in necessary supply resources resulting from any new
water supply resources.
Demand Methodology
The Otay WD water demand projection methodology in the WFMP Update utilizes a
component land use approach. This is done by applying representative values of water use to
the acreage of each land use type and then aggregating these individual land use demand
projections into an overall total demand for the Otay WD. This is called the water duty
method, and the water duty is the amount of water used in gallons per day per acre per year.
This approach is used for all the land use types except residential development where a
demand per dwelling unit was applied. In addition, commercial and industrial water use
categories are further subdivided by type including separate categories for golf courses,
schools, jails, prisons, hospitals, etc. where specific water demands are established.
To determine water duties for the various types of land use, the entire water meter database of
the Otay WD is utilized and sorted by the appropriate land use types. The metered
consumption records are then examined for each of the land uses, and water duties are determined for
the various types of residential, commercial, industrial, and institutional land uses. For example
the water duty factors for commercial and industrial land uses are estimated using 1,785 and 893
gallons per day per acre (gpd/acre) respectively. Residential water demand is established based on
the same data but computed on a per-dwelling unit basis. The focus is to ensure that for each of the
residential land use categories (very low, low, medium, and high densities), the demand criteria
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
15
used is adequately represented based upon actual data. This method is used because
residential land uses constitute a substantial percentage of the total developable planning area of the
Otay WD.
The WFMP Update calculates potable water demand by taking the gross acreage of a site and
applying a potable water reduction factor (PWRF), which is intended to represent the
percentage of acreage to be served by potable water and that not served by recycled water for
irrigation. For industrial land use, as an example, the PWRF is 0.95 (i.e., 95% of the site is
assumed to be served by potable water, 5% of the site is assumed to be irrigated with recycled
water, if available). The potable net acreage is then multiplied by the unit demand factor
corresponding to its respective land use. This approach is used in the WFMP Update for all
the land use types except residential development where a demand per dwelling unit is
applied. In addition, commercial and industrial water use categories are further subdivided by
type including separate categories for golf courses, schools, jails, prisons, hospitals, etc.
where specific water demands are allocated.
Otay Water District Projected Demand
By applying the established water duties to the proposed land uses, the projected water
demand for the entire Otay WD planning area at ultimate development is determined.
Projected water demands for the intervening years were determined using growth rate
projections consistent with data obtained from SANDAG and the experience of the Otay WD.
The historical and projected potable water demands for Otay WD are shown in Table 1.

5.1 Demand Management (Water-Use Efficiency)
Demand management, or water-use efficiency is a critical part of the Otay Water District’s
2015 Urban Water Management Plan (UWMP) and its long-term strategy for meeting the
water supply needs of its customers. Water conservation is frequently the lowest cost
resource available to any water agency. The Otay WD’s water conservation program
objectives are to:
• Reduce the demand for more expensive, imported water.
• Ensure a reliable water supply.
The Otay WD was one of the original signatories to the Memorandum of Understanding
(MOU) regarding Urban Water Conservation in California, which created the California
Urban Water Conservation Council (CUWCC) in 1991 in an effort to reduce California's
long-term water demands. The Otay WD has been a long-standing supporter of the
CUWCC through its implementation of Best Management Practices (BMPs), which
required the District to submit biannual reports that detailed the implementation of its
conservation programs. As a result of the 2014-2017 drought and the state’s changing
regulatory, political, social, economic, and environmental climate, CUWCC members
and its Board, in 2017, restructured the organization and renamed it the California Water
Efficiency Partnership (CWEP). The new framework allows the organization to better
fulfill its members’ needs, quickly adapt to the changing climate, provide resources
about water-use efficiency issues in California, and foster collaboration among a wide
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
19
variety of stakeholders. The Otay WD is currently a member of CWEP as part of its
effort to continue upholding its long-term commitment in reducing the state’s water
demands, diversifying local water supply, and encouraging its customer to make
conservation a way of life. In addition to meeting customer demands during a drought,
the District consistently advocates for state policies and legislation that include supply
development and water-use efficiency. The District continues to work closely with the
Water Authority, the Association of California Water Agencies, and other water
agencies in the region to ensure that the targets and measures in the State Water
Resources Control Board’s (SWRCB) long-term framework support a balanced
approach and reflect local water supply investments and conditions.
Water conservation programs are developed and implemented on the premise that water
conservation increases the local water supply by reducing the demand on available imported
supply, which is vital to the optimal utilization of a region's water supply resources. The
Otay WD participates in many water conservation programs designed and typically operated
on a shared cost-participation program basis among the Water Authority, MWD, and their
member agencies. The demands shown in Tables 1 and 2 take into account
implementation of water conservation measures within Otay WD.
As part of the preceding CUWCC’s BMPs requirements, the Otay WD implemented water
conservation programs and provided services to its customers to promote water-use efficiencies
and water savings. It continues to do so today. As a member of the Water Authority, Otay
WD also benefits from regional programs performed on behalf of its member agencies. In
partnership with the Water Authority, the County of San Diego, City of San Diego, City of
Chula Vista, and developers, the Otay WD water-use efficiency efforts are expected to
grow and expand. The resulting savings directly relate to additional available water in the
San Diego County region for beneficial use within the Water Authority service area,
including the Otay WD.
Additional conservation or water-use efficiency measures or programs practiced by the
Otay WD include the following:
Supervisory Control and Data Acquisition System
The Otay WD implemented and has operated for many years a Supervisory Control and
Data Acquisition (SCADA) system to control, monitor, and collect data regarding the
operation of the water system. The major facilities that have SCADA capabilities are the
water-flow control supply sources, transmission network, pumping stations, and water
storage reservoirs. The SCADA system allows for many and varied useful functions. Some
of the functions they provide for operating personnel are the ability to monitor the water
supply source flow rates, reservoir levels, tum on or off pumping units, etc. The SCADA
system aids in the prevention of water reservoir overflow events and increases energy
efficiency.

the customers, resulting in the conservation of water supplies for that public entity. In
1988, the Otay WD Board of Directors established a comprehensive water conservation
program pursuant to California Water Code Sections 375 et seq., based upon the need to
conserve water supplies and to avoid or minimize the effects of any future shortage. A
water shortage could exist based upon the occurrence of one or more of the following
conditions:
1. A general water supply shortage due to increased demand or limited supplies.
2. Distribution or storage facilities of the Water Authority or other agencies
become inadequate. 3. A major failure of the supply, storage, and distribution facilities of MWD, Water Authority, and/or Otay WD.
The Otay WD water conservation ordinance specifies that the conditions prevailing in the San
Diego County area require that the available water resources be put to maximum beneficial use
to the extent to which they are capable, and that the waste or unreasonable use, or unreasonable
method of use, of water be prevented. In addition, the ordinance encourages the conservation
of such water with a view to the maximum reasonable and beneficial use thereof in the interests
of the people of the Otay WD and for the public welfare.
Otay WD continues to promote water-use efficiency and conservation at community and
business events, including those involving developers in its service area. In addition,
Otay WD, working with the Water Authority and MWD manages a number of programs.
Otay WD is currently engaged in a number of conservation and water-use efficiency activities.
Listed below are programs that either are current or have been concluded:
• Residential Water Surveys
• Large Landscape Surveys
• Cash for Water Smart Plants Landscape Retrofit Program
• Rotating Nozzles Rebates
• Residential Weather-Based Irrigation Controller (WBIC) Incentive Program
• Residential High Efficiency Clothes Washers
• Residential ULFT/HET Rebate Program
• Outreach Efforts to Otay WD Customers - the Otay WD promotes its conservation
programs through outreach at community and business events, bill inserts, articles
in the Otay WD's quarterly customer Pipeline newsletter, direct mailings to Otay
WD customers, the Otay WD's webpage and social media platforms, and through
the Water Authority's marketing efforts.
• School Education Programs - the Otay WD funds school tours of the Water
Conservation Garden and school assemblies, co-funds Splash Labs, and maintains

• Landscape Contest for homeowners in the Otay WD’s service area
The county’s residents and businesses also exceeded the SWRCB’s emergency water-use
reduction mandates during 2015 and 2016, and they continue to use less water than they did in
2013 even though drought conditions have ended. Since the SWRCB’s conservation mandate
began in June 2015, Otay customers have saved an average of 16 to 19 percent more water
compared to 2013 water-use totals.
Section 6 - Existing and Projected Supplies
The Otay WD currently does not have an independent raw or potable water supply source.
The Otay WD is a member public agency of the Water Authority and the Water Authority is
a member public agency of MWD. The statutory relationships between the Water Authority
and its member agencies, and MWD and its member agencies, respectively, establish the
scope of the Otay WD entitlement to water from these two agencies.
The Water Authority currently supplies the Otay WD with 100 percent of its potable water
through two delivery pipelines, referred to as Pipeline No. 4 and the Helix Flume Pipeline.
The Water Authority in turn, currently purchases the majority of its water from MWD. Due
to the Otay WD reliance on these two agencies, this WSA&V Report includes referenced
documents that contain information on the existing and projected supplies, supply programs,
and related projects of the Water Authority and MWD. The Otay WD, Water Authority, and
MWD are actively pursuing programs and projects to further diversify their water supply
resources.
The description of local recycled water supplies available to the Otay WD is also discussed
below.
6.1 Metropolitan Water District of Southern California 2015 Urban
Water Management Plan
MWD has prepared its 2015 UWMP which was adopted on May 9, 2016. The 2015 UWMP
provides MWD’s member agencies, retail water utilities, cities, and counties within its service
area with, among other things, a detailed evaluation of the supplies necessary to meet future
demands, and an evaluation of reasonable and practical efficient water uses, recycling, and
conservation activities. During the preparation of the 2015 UWMP, MWD utilized the
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
22
previous SANDAG regional growth forecast in calculating regional water demands for the
Water Authority service area.
6.1.1 Availability of Sufficient Supplies and Plans for Acquiring
Additional Supplies
MWD is a wholesale supplier of water to its member public agencies and obtains its supplies
from two primary sources: the Colorado River, via the Colorado River Aqueduct (CRA),
which it owns and operates, and Northern California, via the State Water Project (SWP). The
2015 UWMP documents the availability of these existing supplies and additional supplies
necessary to meet future demands.
MWD’s IRP identifies a mix of resources (imported and local) that, when implemented, will
provide 100 percent reliability for full-service demands through the attainment of regional
targets set for conservation, local supplies, State Water Project supplies, Colorado River
supplies, groundwater banking, and water transfers. The 2015 update to the IRP (2015 IRP
Update) describes an adaptive management strategy to protect the region from future supply
shortages. This adaptive management strategy has five components: achieve additional
conservation savings, develop additional local water supplies, maintain Colorado River
Aqueduct supplies, stabilize State Water Project supplies, and maximize the effectiveness of
storage and transfer. MWD’s 2015 IRP Update has a plan for identifying and implementing
additional resources that expand the ability for MWD to meet future changes and challenges
as necessary to ensure future reliability of supplies. The proper management of these
resources help to ensure that the southern California region, including San Diego County, will
have adequate water supplies to meet long-term future demands.
In May 2016, MWD adopted its 2015 UWMP in accordance with state law. The resource
targets included in the preceding 2015 IRP Update serve as the foundation for the planning
assumptions used in the 2015 UWMP. MWD’s 2015 UWMP contains a water supply
reliability assessment that includes a detailed evaluation of the supplies necessary to meet
demands over a 20-year period in average, single dry year, and multiple dry year periods. As
part of this process, MWD also uses the current SANDAG regional growth forecast in
calculating regional water demands for the Water Authority’s service area.
As stated in MWD’s 2015 UWMP, the plan may be used as a source document for meeting
the requirements of SB 610 and SB 221 until the next scheduled update is completed in 5
years (2020). The 2015 UWMP includes a “Justifications for Supply Projections” in
Appendix A.3, that provides detailed documentation of the planning, legal, financial, and
regulatory basis for including each source of supply in the plan. A copy of MWD’s 2015
UWMP can be found on the internet at the following site address:

The UWMP updates for both MWD and the Water Authority included the increase in demand
projections included in SANDAG’s Series 13 Update and from the projections from Otay
Water District WFMP Update.
Water supply agencies throughout California continue to face climate, environmental, legal,
and other challenges that impact water source supply conditions, such as the court rulings
regarding the Sacramento-San Joaquin Delta and the current western states drought
conditions. Challenges such as these essentially always will be present. The regional water
supply agencies, the Water Authority and MWD, along with Otay WD nevertheless fully
intend to have sufficient, reliable supplies to serve demands.
6.1.2 MWD Capital Investment Plan
MWD prepares a Capital Investment Plan as part of its annual budget approval process. The
cost, purpose, justification, status, progress, etc. of MWD’s infrastructure projects to deliver
existing and future supplies are documented in the Capital Investment Plan. The financing of
these projects is addressed as part of the annual budget approval process.
MWD’s Capital Investment Plan includes a series of projects identified from MWD studies of
projected water needs, which, when considered along with operational demands on aging
facilities and new water quality regulations, identify the capital projects needed to maintain
infrastructure reliability and water quality standards, improve efficiency, and provide future
cost savings. All projects within the Capital Investment Plan are evaluated against an
objective set of criteria to ensure they are aligned with the MWD’s goals of supply reliability
and quality.
6.2 San Diego County Water Authority Regional Water Supplies
The Water Authority has adopted plans and is taking specific actions to develop adequate
water supplies to help meet existing and future water demands within the San Diego region.
This section contains details on the supplies being developed by the Water Authority. A
summary of recent actions pertaining to development of these supplies includes:
In accordance with the Urban Water Management Planning Act, the Water Authority
adopted their 2015 UWMP in June 2016. The updated Water Authority 2015 UWMP
identifies a diverse mix of local and imported water supplies to meet future demands. A
copy of the updated Water Authority 2015 UWMP can be found on the internet at:

As part of the October 2003 Colorado River Quantification Settlement Agreement
(QSA), the Water Authority was assigned MWD’s rights to 77,700 acre feet per year of
conserved water from the All-American Canal (AAC) and Coachella Canal (CC) lining
projects. Deliveries of this conserved water from the CC reached the region in 2007 and
deliveries from the AAC reached the region in 2010. Expected supplies from the canal
lining projects are considered verifiable Water Authority supplies.
Deliveries of conserved agricultural water from the Imperial Irrigation District (IID) to
San Diego County have increased annually since 2003, with 70,000 acre feet per year of
deliveries in Fiscal Year (FY) 2010. The quantities will increase annually to 200,000
acre feet per year by 2021, and then remain fixed for the duration of the transfer
agreement.
Development of seawater desalination in San Diego County assists the region in
diversifying its water resources; reduces dependence on imported supplies; and provides
a new drought‐proof, locally treated water supply. The Carlsbad Desalination Project is
a fully operational seawater desalination plant and conveyance pipeline developed by
Poseidon, a private investor–owned company that develops water and wastewater
infrastructure. The Carlsbad Desalination Project, located at the Encina Power Station in
Carlsbad, began commercial operation on December 23, 2015, and can provide a highly
reliable local supply of up to 56,000 AF/YR for the region. Of the total Carlsbad
Desalination Plant production, Vallecitos Water District has a direct connection and a
contract to receive 4,083 AFY. Carlsbad MWD has agreed to a take or pay of 2,500
AFY but a direct connection has not been built.
Through implementation of the Water Authority and member agency planned supply projects,
along with reliable imported water supplies from MWD, the region anticipates having
adequate supplies to meet existing and future water demands.
To ensure sufficient supplies to meet projected growth in the San Diego region, the Water
Authority uses the SANDAG most recent regional growth forecast in calculating regional
water demands. The SANDAG regional growth forecast is based on the plans and policies of
the land-use jurisdictions with San Diego County. The existing and future demands of the
member agencies are included in the Water Authority’s projections.

6.2.1 Availability of Sufficient Supplies and Plans for Acquiring
Additional Supplies
The Water Authority currently obtains imported supplies from MWD, conserved water from
the AAC and CC lining projects, an increasing amount of conserved agricultural water from
IID, and desalinated seawater from the Carlsbad desalination plant. Of the twenty-seven
member agencies that purchase water supplies from MWD, the Water Authority is MWD’s
largest customer.
Section 135 of MWD’s Act defines the preferential right to water for each of its member
agencies. Currently, the Water Authority pays about 22 percent of MWD's total revenue, but
has preferential rights to only 18.27 percent of MWD's water supply. Under preferential
rights, MWD could allocate water without regard to historic water purchases or dependence
on MWD. The Water Authority and its member agencies are taking measures to reduce
dependence on MWD through development of additional supplies and a water supply
portfolio that would not be jeopardized by a preferential rights allocation. MWD has stated,
consistent with Section 4202 of its Administrative Code that it is prepared to provide the
Water Authority’s service area with adequate supplies of water to meet expanding and
increasing needs in the years ahead. When and as additional water resources are required to
meet increasing needs, MWD stated it will be prepared to deliver such supplies. In Section
ES-5 of their 2015 UWMP, MWD states that MWD has supply capacities that would be
sufficient to meet expected demands from 2020 through 2040. MWD has plans for supply
implementation and continued development of a diversified resource mix including programs
in the Colorado River Aqueduct, State Water Project, Central Valley Transfers, local resource
projects, and in-region storage that enables the region to meet its water supply needs.
The Water Authority has made large investments in MWD’s facilities and will continue to
include imported supplies from MWD in the future resource mix. As discussed in the Water
Authority’s 2015 UWMP, the Water Authority and its member agencies are planning to
diversify the San Diego regions supply portfolio and reduce purchases from MWD.
As part of the Water Authority’s diversification efforts, the Water Authority is now taking
delivery of conserved agricultural water from IID, water saved from the AAC and CC lining
projects and desalinated seawater from the Carlsbad desalination plant. Table 3 summarizes
the Water Authority’s supply sources with detailed information included in the sections to
follow. Deliveries from MWD are also included in Table 3, which is further discussed in
Section 6.1 above. The Water Authority’s member agencies provided the verifiable local
supply targets for groundwater, recycled water, potable reuse and surface water, which are
discussed in more detail in Section 5 of the Water Authority’s 2015 UWMP.

Section 5.6.1 of the Water Authority’s 2015 UWMP also includes a discussion on the local
supply target for seawater desalination. Seawater desalination supplies represent a significant
local resource in the Water Authority’s service area.
The Carlsbad Desalination Project (Project) is a fully-permitted seawater desalination plant
and conveyance pipeline designed to provide a highly reliable local supply of up to 56,000
acre-feet (AF) per year for the region. In 2020, the Project would account for approximately
8% of the total projected regional supply and 30% of all locally generated water in San Diego
County. The project became operational in late 2015 and it more than doubles the amount of
local supplies developed in the region since 1991. The desalination plant itself was fully
financed, built, and is being operated by Poseidon. The Water Authority purchases water
from the plant under a water purchase agreement. The new pipeline connecting the
desalination plant with the Water Authority’s Second Aqueduct is owned and operated by the
Water Authority, but Poseidon had the responsibility for design and construction through a
separate Design-Build Agreement. The Water Authority was responsible for aqueduct
improvements, including the relining and rehabilitation of Pipeline 3 to accept desalinated
water under higher operating pressures, modifications to the San Marcos Vent that allows the
flow of water between Pipelines 3 and 4, and improvements at the Twin Oaks Valley Water
Treatment Plant necessary to integrate desalinated water into the Water Authority’s system
for optimal distribution to member agencies.
The Water Authority’s existing and planned supplies from the IID transfer, canal lining, and
desalination projects are considered “drought-proof” supplies and should be available at the
Otay Water District

yields shown in Table 4 in normal water year supply and demand assessment. Single dry year
and multiple dry year scenarios are discussed in more detail in Section 9 of the Water
Authority’s 2015 UWMP.
As part of preparation of a written water supply assessment and/or verification report, an
agency’s shortage contingency analysis should be considered in determining sufficiency of
supply. Section 11 of the Water Authority’s 2015 UWMP contains a detailed shortage
contingency analysis that addresses a regional catastrophic shortage situation and drought
management. The analysis demonstrates that the Water Authority and its member agencies,
through the Emergency Response Plan, Emergency Storage Project, and Drought
Management Plan (DMP) are taking actions to prepare for and appropriately handle an
interruption of water supplies. The Water Authority’s Board of Directors approved the
Drought Management Plan (DMP) in 2006. The DMP outlined a series of orderly, progressive
steps for the Water Authority and its member agencies to take during shortages to minimize
impacts to the region’s economy and quality of life. It also included an allocation
methodology to equitably allocate water supplies to the member agencies. The DMP was first
activated in 2007 in response to MWD drawing water from storage to meet demands, and
deactivated in 2011 when supply conditions improved.
In 2008, the Water Authority’s Board approved another drought management document, the
Model Drought Response Conservation Program Ordinance. The model ordinance focuses on
core water use restrictions and is intended to assist the member agencies when updating or
drafting local drought response ordinances. The intent of the model ordinance is to provide
regional consistency in drought response levels and messaging to the public and media. Also
in 2008, the Water Authority’s Board adopted Resolution 2008-11, that established
procedures to administer the supply allocation methodology contained in the DMP.
In 2012, the DMP’s supply allocation methodology was updated, using lessons from the
previous shortage periods, and the DMP was renamed the Water Shortage and Drought
Response Plan (WSDRP). In 2014, the WSDRP was activated due to critically dry weather in
California and the impact on water supply conditions. It deactivated in 2016 when supply
conditions improved.
In each instance when the DMP and WSDRP were activated, a smooth transition into and out
of water allocations for the member agencies was possible due to the advanced planning of
the Water Authority and its member agencies. Those planning efforts also resulted in an
approach that allowed for regional consistency in public drought messaging.
On August 24, 2017, the Water Authority’s Board approved proposed revisions of the
WSDRP and renamed it the Water Shortage Contingency Plan (WSCP) to align the WSCP
with the framework outlined in the April 2017 Final Report, Making Water Conservation a
California Way of Life, Implementing Executive Order B-37-16 in the areas of water use
efficiency and shortage response planning. The WSCP continues a proactive and
comprehensive approach to shortage response planning for the region. The plan will be
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
28
reviewed and potentially updated at least every five years in coordination with the preparation
of the Water Authority’s Urban Water Management Plan for 2020, which will include any
final requirements approved through legislation implementing the state’s framework report.
The approval of the WSCP does not require the member agencies to update their planning
document or conservation ordinance at this time.
6.2.1.1 Water Authority-Imperial Irrigation District Water Conservation
and Transfer Agreement
The QSA was signed in October 2003, and resolves long-standing disputes regarding priority
and use of Colorado River water and creates a baseline for implementing water transfers. With
approval of the QSA, the Water Authority and IID were able to implement their Water
Conservation and Transfer Agreement. This agreement not only provides reliability for the San
Diego region, but also assists California in reducing its use of Colorado River water to its legal
allocation.
On April 29, 1998, the Water Authority signed a historic agreement with IID for the long-term
transfer of conserved Colorado River water to San Diego County. The Water Authority-IID
Water Conservation and Transfer Agreement (Transfer Agreement) is the largest agriculture-to-
urban water transfer in United States history. Colorado River water will be conserved by
Imperial Valley farmers who voluntarily participate in the program and then transferred to the
Water Authority for use in San Diego County.
Implementation Status
On October 10, 2003, the Water Authority and IID executed an amendment to the original 1998
Transfer Agreement. This amendment modified certain aspects of the Transfer Agreement to be
consistent with the terms and conditions of the QSA and related agreements. It also modified
other aspects of the agreement to lessen the environmental impacts of the transfer of conserved
water. The amendment was expressly contingent on the approval and implementation of the
QSA, which was also executed on October 10, 2003. Section 6.2.1, “Colorado River,” contains
details on the QSA.
On November 5, 2003, IID filed a complaint in Imperial County Superior Court seeking
validation of 13 contracts associated with the Transfer Agreement and the QSA. Imperial
County and various private parties filed additional suits in Superior Court, alleging violations of
the California Environmental Quality Act (CEQA), the California Water Code, and other laws
related to the approval of the QSA, the water transfer, and related agreements. The lawsuits were
coordinated for trial. The IID, Coachella Valley Water District, MWD, the Water Authority, and
state are defending these suits and coordinating to seek validation of the contracts. In January
2010, a California Superior Court judge ruled that the QSA and 11 related agreements were
invalid, because one of the agreements created an open-ended financial obligation for the state,
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
29
in violation of California’s constitution. The QSA parties appealed this decision and on July
2013, a Sacramento Superior Court judge entered a final judgment validating the QSA and
rejecting all of the remaining legal challenges. The judge affirmed all of the contested actions,
including the adequacy of the environmental documents prepared by the IID. In May 2015, the
state Court of Appeal issued a ruling that dismissed all remaining appeals.
Expected Supply
Deliveries into San Diego County from the transfer began in 2003 with an initial transfer of
10,000 acre feet per year. The Water Authority received increasing amounts of transfer water
each year, according to a water delivery schedule contained in the transfer agreement The
quantities will increase annually to 200,000 acre feet per year by 2021 then remain fixed for the
duration of the transfer agreement. The initial term of the Transfer Agreement is 45 years, with a
provision that either agency may extend the agreement for an additional 30-year term.
During dry years, when water availability is low, the conserved water will be transferred
under IID’s Colorado River rights, which are among the most senior in the Lower Colorado
River Basin. Without the protection of these rights, the Water Authority could suffer delivery
cutbacks. In recognition for the value of such reliability, the 1998 contract required the Water
Authority to pay a premium on transfer water under defined regional shortage circumstances.
The shortage premium period duration is the period of consecutive days during which any of the
following exist: 1) a Water Authority shortage; 2) a shortage condition for the Lower Colorado
River as declared by the Secretary; and 3) a Critical Year. Under terms of the October 2003
amendment, the shortage premium will not be included in the cost formula until Agreement Year
16.
Transportation
The Water Authority entered into a water exchange agreement with MWD on October 10, 2003,
to transport the Water Authority–IID transfer water from the Colorado River to San Diego
County. Under the exchange agreement, MWD takes delivery of the transfer water through its
Colorado River Aqueduct. In exchange, MWD delivers to the Water Authority a like quantity
and quality of water. The Water Authority pays MWD’s applicable wheeling rate for each acre-
feet of exchange water delivered. Under the terms of the water exchange agreement, MWD will
make delivery of the transfer water for 35 years, unless the Water Authority and MWD elect to
extend the agreement another 10 years for a total of 45 years.
Cost/Financing
The costs associated with the transfer are financed through the Water Authority’s rates and
charges. In the agreement between the Water Authority and IID, the price for the transfer water
started at $258 per acre-feet and increased by a set amount for the first seven years. In December
2009, the Water Authority and IID executed a fifth amendment to the water transfer agreement
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
30
that sets the price per acre-feet for transfer water for calendar years 2010 through 2015,
beginning at $405 per acre-feet in 2010 and increasing to $624 per acre-feet in 2015. For
calendar years 2016 through 2034, the unit price will be adjusted using an agreed-upon index.
The amendment also required the Water Authority to pay IID $6 million at the end of calendar
year 2009 and another $50 million on or before October 1, 2010, provided that a transfer
stoppage is not in effect as a result of a court order in the QSA coordinated cases. Beginning in
2035, either the Water Authority or IID can, if certain criteria are met, elect a market rate price
through a formula described in the water transfer agreement.
The October 2003 exchange agreement between MWD and the Water Authority set the initial
cost to transport the conserved water at $253 per acre-feet. Thereafter, the price is set to be equal
to the charge or charges set by MWD’s Board of Directors pursuant to applicable laws and
regulation, and generally applicable to the conveyance of water by MWD on behalf of its
member agencies.
The Water Authority is providing $10 million to help offset potential socioeconomic impacts
associated with temporary land fallowing. IID will credit the Water Authority for these funds
during years 16 through 45. In 2007, the Water Authority prepaid IID an additional $10 million
for future deliveries of water. IID will credit the Water Authority for this up-front payment
during years 16 through 30.
As part of implementation of the QSA and water transfer, the Water Authority also entered into
an environmental cost sharing agreement. Under this agreement the Water Authority is
contributing a total of $64 million to fund environmental mitigation projects and the Salton Sea
Restoration Fund.
Written Contracts or Other Proof
The supply and costs associated with the transfer are based primarily on the following
documents:
Agreement for Transfer of Conserved Water by and between IID and the Water Authority (April
29, 1998). This Agreement provides for a market-based transaction in which the Water
Authority would pay IID a unit price for agricultural water conserved by IID and transferred to
the Water Authority.
Revised Fourth Amendment to Agreement between IID and the Water Authority for Transfer of
Conserved Water (October 10, 2003). Consistent with the executed Quantification Settlement
Agreement (QSA) and related agreements, the amendments restructure the agreement and
modify it to minimize the environmental impacts of the transfer of conserved water to the Water
Authority.

6.2.1.2 All-American Canal and Coachella Canal Lining Projects
As part of the QSA and related contracts, the Water Authority was assigned MWD’s rights to
77,700 acre-feet per year of conserved water from projects that will line the All-American
Canal (AAC) and Coachella Canal (CC). The projects will reduce the loss of water that
currently occurs through seepage, and the conserved water will be delivered to the Water
Authority. This conserved water will provide the San Diego region with an additional 8.5
million acre-feet over the 110-year life of the agreement.
Implementation Status
The CC lining project began in November 2004 and was completed in 2006. Deliveries of
conserved water to the Water Authority began in 2007. The project constructed a 37-mile
parallel canal adjacent to the CC. The AAC lining project was begun in 2005 and was
completed in 2010. The lining project constructed a concrete-lined canal parallel to 24 miles
of the existing AAC from Pilot Knob to Drop 3.
In July 2005, a lawsuit (CDEM v United States, Case No. CV-S-05-0870-KJD-PAL) was filed
in the U. S. District Court for the District of Nevada on behalf of U.S. and Mexican groups
challenging the lining of the AAC. The lawsuit, which names the Secretary of the Interior as
a defendant, claims that seepage water from the canal belongs to water users in Mexico.
California water agencies note that the seepage water is actually part of California's Colorado
River allocation and not part of Mexico's allocation. The plaintiffs also allege a failure by the
United States to comply with environmental laws. Federal officials have stated that they
intend to vigorously defend the case.
Expected Supply
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
33
The AAC lining project makes 67,700 acre-feet of Colorado River water per year available
for allocation to the Water Authority and San Luis Rey Indian water rights settlement parties.
The CC lining project makes 26,000 acre-feet of Colorado River water each year available for
allocation. The 2003 Allocation Agreement provides for 16,000 acre-feet per year of
conserved canal lining water to be allocated to the San Luis Rey Indian Water Rights
Settlement Parties. The remaining amount, 77,700 acre-feet per year, is to be available to the
Water Authority, with up to an additional 4,850 acre-feet per year available to the Water
Authority depending on environmental requirements from the CC lining project. For planning
purposes, the Water Authority assumes that 2,500 acre-feet of the 4,850 acre-feet will be
available each year for delivery, for a total of 80,200 acre-feet per year of that supply.
According to the Allocation Agreement, IID has call rights to a portion (5,000 acre-feet per
year) of the conserved water upon termination of the QSA for the remainder of the 110 years
of the Allocation Agreement and upon satisfying certain conditions. The term of the QSA is
for up to 75 years.
Transportation
The October 2003 Exchange Agreement between the Water Authority and MWD provides for
the delivery of the conserved water from the canal lining projects. The Water Authority pays
MWD’s applicable wheeling rate for each acre-foot of exchange water delivered. In the
Agreement, MWD will deliver the canal lining water for the term of the Allocation
Agreement (110 years).
Cost/Financing
Under California Water Code Section 12560 et seq., the Water Authority received $200
million in state funds for construction of the canal lining projects. In addition, $20 million
was made available from Proposition 50 and $36 million from Proposition 84. The Water
Authority was responsible for additional expenses above the funds provided by the state.
The rate to be paid to transport the canal lining water will be equal to the charge or charges set
by MWD’s Board of Directors pursuant to applicable law and regulation and generally
applicable to the conveyance of water by MWD on behalf of its member agencies.
In accordance with the Allocation Agreement, the Water Authority is responsible for a portion
of the net additional Operation, Maintenance, and Repair (OM&R) costs for the lined canals.
Any costs associated with the lining projects as proposed are to be financed through the Water
Authority’s rates and charges.

6.2.1.3 Carlsbad Seawater Desalination Project
Development of seawater desalination in San Diego County has assisted the region in
diversifying its water resources, reduce dependence on imported supplies, and provide a new
drought-proof, locally treated water supply. The Carlsbad Desalination Project is a fully-
permitted seawater desalination plant and conveyance pipeline developed by Poseidon, a
private investor–owned company that develops water and wastewater infrastructure. The
project, located at the Encina Power Station in Carlsbad, has been in development since 1998
and was incorporated into the Water Authority’s 2003 Water Facilities Master Plan and the
2015 UWMP. The Carlsbad Desalination Project has obtained all required permits and
environmental clearances and starting in late 2015 provides a highly reliable local supply of
48,000 to 56,000 acre-feet per year for the region.
Implementation Status
The Project has obtained all required permits and environmental clearances, including the
following:
National Pollutant Discharge Elimination System (NPDES) Discharge Permit
(Regional Water Quality Control Board)
Conditional Drinking Water Permit (California Department of Health Services)
State Lands Commission Lease (State Lands Commission)
Coastal Development Permit (California Coastal Commission)
IDE Technologies, a worldwide leader in the design, construction, and operation of
desalination plants, is the desalination process contractor for the Project.
On July 22, 2010, the Board approved a Term Sheet between the Water Authority and
Poseidon Resources that outlined the key terms and conditions that would be detailed and
incorporated in a comprehensive Water Purchase Agreement (WPA). Beginning in October
2011 and under the direction of the Board’s Carlsbad Desalination Project Advisory Group,
staff began developing and negotiating with Poseidon a WPA consistent with the July 22,
Otay Water District

37
2010 Board approved Term Sheet. The July 2010 Term Sheet also identified specific
conditions precedent to Board consideration of the WPA.
On November 29, 2012, the Water Authority Board adopted a resolution approving the
Design-Build Agreement between the Water Authority and Poseidon. The Design-Build
Agreement established the commercial and technical terms for implementation of the
desalination product pipeline improvements. These improvements consisted of an
approximate 10-mile long, 54-inch diameter conveyance pipeline connecting the Desalination
Plant to the Water Authority’s Second Aqueduct. The pipeline was generally be constructed
within improved streets in commercial and industrial areas in the cities of Carlsbad, Vista, and
San Marcos. The Water Authority owns the Project Water Pipeline Improvements and has
assumed operational control of all pipeline improvements. This system was placed into
service in late 2015.
Expected Supply
The Project provides a highly reliable local supply of 48,000 to 56,000 acre-feet per year of
supply for the region, available in both normal and dry hydrologic conditions. In 2020, the
Project would account for approximately 10% of the total projected regional supply and 30%
of all locally generated water in San Diego County. The project more than doubles the
amount of local supplies developed in the region since 1991.

The plant and the offsite pipeline is being financed through tax exempt government bonds
issued for the Water Authority by the California Pollution Control Financing Authority
(CPCFA). On November 29, 2012, the Water Authority Board adopted a resolution
approving agreements to accomplish tax exempt project financing through the CPCFA.
Based on current electricity cost estimates, the Water Purchase Agreement sets the price of
the water from the Carlsbad Desalination Project at $2,131 to $2,367 per acre foot in 2016.
The Water Authority’s water purchase costs would be financed through Water Authority rates
and charges. Poseidon is financing the capital cost of the Project with a combination of
private equity and tax-exempt Private Activity Bonds.

6.2.2 Water Authority Capital Improvement Program and Financial
Information
The Water Authority’s Capital Improvement Program (CIP) can trace its beginnings to a
report approved by the Board in 1989 entitled, The Water Distribution Plan, and a Capital
Improvement Program through the Year 2010. The Water Distribution Plan included ten
projects designed to increase the capacity of the aqueduct system, increase the yield from
existing water treatment plants, obtain additional supplies from MWD, and increase the
reliability and flexibility of the aqueduct system. Since that time the Water Authority has
made numerous additions to the list of projects included in its CIP as the region’s
infrastructure needs and water supply outlook have changed.
The current list of projects included in the CIP is based on the results of planning studies,
including the 2015 UWMP and the 2013 Regional Water Facilities Master Plan. These CIP
projects, which are most recently described in the Water Authority’s Adopted Multi-Year
Budget Fiscal Years 2018 and 2019, include projects valued at $118 million. These CIP
projects are designed to meet projected water supply and delivery needs of the member
agencies. The projects include a mix of new facilities that will add capacity to existing
conveyance, storage, and treatment facilities, as well as repair and replace aging
infrastructure:
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project

Asset Management – The primary components of the asset management projects
include relining and replacing existing pipelines and updating and replacing metering
facilities.
New Facilities – These projects will expand the capacity of the aqueduct system and
evaluate new supply opportunities.
Emergency Storage Project – Projects remaining to be completed under the ongoing
ESP include the San Vicente Dam Raise, the Lake Hodges projects, and a new pump
station to extend ESP supplies to the northern reaches of the Water Authority service
area.
Other Projects – This category includes out-of-region groundwater storage, increased
local water treatment plant capacity, and projects that mitigate environmental impacts
of the CIP.
The Water Authority Board of Directors is provided a semi-annual and annual report on the
status of development of the CIP projects. As described in the Water Authority’s biennial
budget, a combination of long and short term debt and cash (pay-as-you-go) will provide
funding for capital improvements. Additional information is included in the Water
Authority’s biennial budget, which also contains selected financial information and
summarizes the Water Authority’s investment policy.
6.3 Otay Water District
The Otay Water District WFMP Update and the 2015 UWMP contain comparisons of
projected supply and demands through the year 2040. Projected potable water resources to
meet planned demands as documented were planned to be supplied entirely with imported
water received from the Water Authority. Recycled water resources to meet projected
demands are planned to be supplied from local wastewater treatment plants. The Otay WD
currently has no local supply of raw water, potable water, or groundwater resources.
The development and/or acquisition of potential groundwater, recycled water market
expansion, and seawater desalination supplies by the Otay WD have evolved and are planned
to occur in response to the regional water supply issues. These water supply projects are in
addition to those identified as sustainable supplies in the current Water Authority and MWD
UWMP, IRP, Master Plans, and other planning documents. These new additional water
supply projects are not currently developed and are in various stages of the planning process.
These local and regional water supply projects will allow for less reliance upon imported
water and are considered a new water supply resource for the Otay WD.
The supply forecasts contained within this WSA Report do consider development and/or
acquisition of potential groundwater, recycled water market expansion, and seawater
desalination supplies by the Otay WD.

6.3.1 Availability of Sufficient Supplies and Plans for Acquiring Additional
Supplies
The availability of sufficient potable water supplies and plans for acquiring additional potable
water supplies to serve existing and future demands of the Otay WD is founded upon the
preceding discussions regarding MWD’s and the Water Authority’s water supply resources
and water supplies to be acquired by the Otay WD. Historic imported water deliveries from
the Water Authority to Otay WD and recycled water deliveries from the Otay WD Ralph W.
Chapman Water Reclamation Facility (RWCWRF) are shown in Table 4. Since the year 2000
through mid-May 2007, recycled water demand has exceeded the recycled water supply
capability typically in the summer months. The RWCWRF is limited to a maximum
production of about 1,300 acre-feet per year. The recycled water supply shortfall had been
met by supplementing with potable water into the recycled water storage system as needed by
adding potable water supplied by the Water Authority. On May 18, 2007 an additional source
of recycled water supply from the City of San Diego’s South Bay Water Reclamation Plant
(SBWRP) became available. The supply of recycled water from the SBWRP is a result of
completing construction and the operation of the transmission, storage, and pump station
systems necessary to link the SBWRP recycled water supply source to the existing Otay WD
recycled water system.

6.3.1.1 Imported and Regional Supplies
The availability of sufficient imported and regional potable water supplies to serve existing
and planned uses within Otay WD is demonstrated in the above discussion on MWD and the
Water Authority’s water supply reliability. The County Water Authority Act, Section 5
subdivision 11, states that the Water Authority “as far as practicable, shall provide each of its
member agencies with adequate supplies of water to meet their expanding and increasing
needs.” The Water Authority provides between 75 to 95 percent of the total supplies used by
its 24 member agencies, depending on local weather and supply conditions.
Potable Water System Facilities
The Otay WD continues to pursue diversification of its water supply resources to increase
reliability and flexibility. The Otay WD also continues to plan, design, and construct potable
water system facilities to obtain these supplies and to distribute potable water to meet
customer demands. The Otay WD has successfully negotiated two water supply
diversification agreements that enhance reliability and flexibility, which are briefly described
as follows.
The Otay WD entered into an agreement with the City of San Diego, known as the Otay
Water Treatment Plant (WTP) Agreement. The Otay WTP Agreement provides for raw
water purchase from the Water Authority and treatment by the City of San Diego at their
Otay WTP for delivery to Otay WD. The supply system link to implement the Otay
WTP Agreement to access the regions raw water supply system and the local water
treatment plant became fully operational in August 2005. This supply link consists of the
typical storage, transmission, pumping, flow measurement, and appurtenances to receive
and transport the treated water to the Otay WD system. The City of San Diego
obligation to supply 10 mgd of treated water under the Otay WTP Agreement is
contingent upon there being available 10 mgd of surplus treatment capacity in the Otay
WTP until such time as Otay WD pays the City of San Diego to expand the Otay WTP to
meet the Otay WD future needs. In the event that the City of San Diego’s surplus is
projected to be less than 10 mgd the City of San Diego will consider and not
unreasonably refuse the expansion of the Otay WTP to meet the Otay WD future needs.
The Otay WTP existing rated capacity is 40 mgd with an actual effective capacity of
approximately 34 mgd. The City of San Diego’s typical demand for treated water from
the Otay WTP is approximately 20 mgd. It is at the City of San Diego’s discretion to
utilize either imported raw water delivered by the Water Authority Pipeline No. 3 or local
water stored in Lower Otay Reservoir for treatment to supply the Otay WD demand.
The Otay WD entered into an agreement with the Water Authority, known as the East
County Regional Treated Water Improvement Program (ECRTWIP Agreement). The
ECRTWIP Agreement provides for transmission of raw water to the Helix WD R. M.
Levy WTP for treatment and delivery to Otay WD. The supply system link to implement
the ECRTWIP Agreement is complete allowing access to the regions raw water supply
Otay Water District
Water Supply Assessment and Verification Report

43
system and the local water treatment plant. This supply link consists of the typical
transmission, pumping, storage, flow control, and appurtenances to receive and transport
the potable water from the R. M. Levy WTP to Otay WD. The Otay WD is required to
take a minimum of 10,000 acre-feet per year of treated water from the R.M. Levy WTP
supplied from the regions raw water system.
Cost and Financing
The capital improvement costs associated with water supply and delivery are financed
through the Otay WD water meter capacity fee and user rate structures. The Otay WD
potable water sales revenue are used to pay for the wholesale cost of the treated water supply
and the operating and maintenance expenses of the potable water system facilities.
Written Agreements, Contracts, or Other Proof
The supply and cost associated with deliveries of treated water from the Otay WTP and the R.M.
Levy WTP is based on the following documents.
Agreement for the Purchase of Treated Water from the Otay Water Treatment Plant between the
City of San Diego and the Otay Water District. The Otay WD entered into an agreement dated
January 11, 1999 with the City of San Diego that provides for 10 mgd of surplus treated water to
the Otay WD from the existing Otay WTP capacity. The agreement allows for the purchase of
treated water on an as available basis from the Otay WTP. The Otay WD pays the Water
Authority at the prevailing raw water rate for raw water and pays the City of San Diego at a rate
equal to the actual cost of treatment to potable water standards.
Agreement between the San Diego County Water Authority and Otay Water District Regarding
Implementation of the East County Regional Treated Water Improvement Program. The
ECRTWIP Agreement requires the purchase of at least 10,000 acre-feet per year of potable water
from the Helix WD R.M. Levy WTP at the prevailing Water Authority treated water rate. The
ECRTWIP Agreement is dated April 27, 2006.
Agreement between the San Diego County Water Authority and Otay Water District for Design,
Construction, Operation, and Maintenance of the Otay 14 Flow Control Facility Modification.
The Otay WD entered into the Otay 14 Flow Control Facility Modification Agreement dated
January 24, 2007 with the Water Authority to increase the physical capacity of the Otay 14 Flow
Control Facility. The Water Authority and Otay WD shared the capital cost to expand its
capacity from 8 mgd to 16 mgd.
Federal, State, and Local Permits/Approvals
The Otay WD acquired all the permits for the construction of the pipeline and pump station
associated with the Otay WTP supply source and for the 640-1 and 640-2 water storage

reservoirs project associated with the ECRTWIP Agreement through the typical planning,
environmental approval, design, and construction processes.
The transmission main project constructed about 26,000 feet of a 36-inch diameter steel
pipeline from the Otay 14 Flow Control Facility to the 640-1 and 640-2 Reservoirs project.
The Otay 14 Flow Control Facility modification increased the capacity of the existing systems
from 8 mgd to 16 mgd. CEQA documentation is complete for both projects. Construction of
both of these projects was completed October 2010.
The City of San Diego and the Helix Water District are required to meet all applicable federal,
state, and local health and water quality requirements for the potable water produced at the
Otay WTP and the R.M. Levy WTP respectively.
6.3.1.2 Recycled Water Supplies
Wastewater collection, treatment, and disposal services provided by the Otay WD is limited to
a relatively small area within what is known as the Jamacha Basin, located within the Middle
Sweetwater River Basin watershed upstream of the Sweetwater Reservoir and downstream of
Loveland Reservoir. Water recycling is defined as the treatment and disinfection of
municipal wastewater to provide a water supply suitable for non-potable reuse. The Otay WD
owns and operates the Ralph W. Chapman Water Reclamation Facility, which produces
recycled water treated to a tertiary level for landscape irrigation purposes. The recycled water
market area of the Otay WD is located primarily within the eastern area of the City of Chula
Vista. The Otay WD distributes recycled water to a substantial market area that includes but
is not limited to the U.S. Olympic Training Center, the Eastlake Golf Course, Otay Ranch,
and other development projects.
The Otay WD projects that annual average demands for recycled water will increase to 6,500
acre-feet per year by 2050. About 1,300 acre-feet per year of supply is generated by the
RWCWRF, with the remainder planned to be supplied to Otay WD by the City of San
Diego’s SBWRP.
North District Recycled Water Concept
The Otay WD is a recognized leader in the use of recycled water for irrigation and other
commercial uses. The Otay WD continues to investigate all viable opportunities to expand
the successful recycled water program into areas that are not currently served. One of these
areas is in the portion of the service area designated as the North District, located within the
Middle Sweetwater River Basin watershed upstream of the Sweetwater River. The close
proximity of the recycled water markets in the North District to the Otay WD source of
recycled water, the RWCWRF, means that the distribution system to serve this area could be
constructed relatively cost effectively. This makes the North District a logical location for the
expansion of the Otay WD recycled water system and market area.

The purpose of the North District Recycled Water System Development Project, Phase I
Concept Study, was to identify the feasibility of using recycled water in the North District and
to investigate and assess any limitations or constraints to its use. The Phase I study
components of the North District Recycled Water Concept encompassed the preparation of
six technical memorandums including the project definition, a discussion of the regulatory
process, a discussion of the protection of the watershed that would be affected by recycled
water use in the North District, identification of stakeholders, public outreach, and an
implementation plan.
Several opportunities that could be realized with the implementation of the use of recycled
water in the North District were identified. These include a reduction of demand on the
potable water system and maximizing recycled water resources which in turn minimizes
treated wastewater discharges to the local ocean outfall. Other opportunities are a possible
partnership with Sweetwater Authority to monitor any benefits and impacts of increased
recycled water use in the watershed and stakeholder outreach to resolve any water quality
concerns and to retain consumer confidence. Also identified were two major constraints
associated with the North District Recycled Water System Development Project. One
constraint is the water quality objectives for the Middle Sweetwater Basin that will affect the
effluent limitations for the recycled water produced at the RWCWRF. The effluent limit of
concern was total nitrogen. The RWCWRF underwent an upgrade in 2012 to enhance
nitrogen removal through the treatment process. The other major constraint is the cost of the
infrastructure needed to convey and store recycled water in the North District. These costs
are estimated to be in the range of $14 to $15 million dollars.
There are two additional phases proposed for the North District Recycled Water System
Development Project. Phase II would include further investigation of the issues identified in
Phase I as requiring further study. These include stakeholder outreach, regulatory issues, and
facility planning. The third phase of the effort would include the facility planning, permitting,
environmental compliance, design, and construction of the improvements necessary for
delivery of recycled water to the North District markets.
The estimated amount of imported water saved at full implementation of the North District
Recycled Water System Development Project is 1,200 acre-feet per year. This saved
imported water could then be used to offset new potable water demands.

Recycled Water System Facilities
The Otay WD has constructed recycled water storage, pumping, transmission, and distribution
facilities and will continue to construct these facilities to meet projected recycled water
market demands. The Supply Link project consisting of a transmission main, storage
reservoir, and a pump station to receive and transport the recycled water from the City of San
Diego’s SBWRP was completed in 2007 and recycled water deliveries began on May 18,
2007.
Cost and Financing
The capital improvement costs associated with the recycled water supply and distribution
systems are financed through the Otay WD water meter capacity fee and user rate structures.
The Otay WD recycled water sales revenue, along with MWD and the Water Authority’s
recycled water sales incentive programs are used to help offset the costs for the wholesale
purchase and production of the recycled water supply, the operating and maintenance
expenses, and the capital costs of the recycled water system facilities.
Written Agreements, Contracts, or Other Proof
The supply and cost associated with deliveries of recycled water from the SBWRP is based on
the following document.
Agreement between the Otay Water District and the City of San Diego for Purchase of
Reclaimed Water from the South Bay Water Reclamation Plant. The agreement provides for the
purchase of at least 6,721 acre-feet per year of recycled water from the SBWRP at an initial price
of $350 per acre-foot. The Otay Water District Board of Directors approved the final agreement
on June 4, 2003 and the San Diego City Council approved the final agreement on October 20,
2003. Effective January 1, 2016, the City of San Diego raised the cost of recycled water 116% to
$754 per acre-foot.
Federal, State, and Local Permits/Approvals
The Otay WD has in place an agreement with MWD for their recycled water sales incentive
program for supplies from the RWCWRF and the SBWRP. Also, the Otay WD has in place
an agreement with the Water Authority for their recycled water sales incentive program for
supplies from the RWCWRF and the SBWRP. The Water Authority sales incentive
agreement was approved by Water Authority on July 26, 2007 and by Otay WD on August 1,
2007. All permits for the construction of the recycled water facilities to receive, store, and
pump the SBWRP supply have been acquired through the typical planning, environmental
approval, design, and construction processes.
The California Regional Water Quality Control Board San Diego Region (RWQCB) “Master
Reclamation Permit for Otay Water District Ralph W. Chapman Reclamation Facility” was
adopted on May 9, 2007 (Order No. R9-2007-0038). This order establishes master

reclamation requirements for the production, distribution, and use of recycled water in the
Otay WD service area. The order includes the use of tertiary treated water produced and
received from the City of San Diego‘s SBWRP. Recycled water received from and produced
by the SBWRP is regulated by Regional Board Order No. 2000-203 and addenda. The City
of San Diego is required to meet all applicable federal, state, and local health and water
quality requirements for the recycled water produced at the SBWRP and delivered to Otay
WD in conformance with Order No. 2000-203.
6.3.1.3 Potential Groundwater Supplies
The Otay Water District WFMP Update, 2015 UWMP, and the 2015 Integrated Water
Resources Plan Update all contain a description of the development of potential groundwater
supplies. Over the past several years, Otay WD has studied numerous potential groundwater
supply options that have shown, through groundwater monitoring well activities, poor quality
water and/or insufficient yield from the basins at a cost effective level. The Otay WD has
developed capital improvement program projects to continue the quest to develop potential
groundwater resources. Local Otay WD groundwater supply development is currently
considered as a viable water supply resource to meet projected demands.
The development and/or acquisition of potential groundwater supply projects by the Otay WD
have been on hold in response to the regional water supply issues related to water source
supply conditions. Local ground water supply projects will allow for less reliance upon
imported water, achieve a level of independence of the regional wholesale water agencies, and
diversify the Otay WD water supply portfolio consistent with the Otay Water District 2015
IRP Update.
In recognition of the need to develop sufficient alternative water supplies, the Otay WD has
taken the appropriate next steps towards development of production groundwater well
projects.
There are three groundwater well projects that the Otay WD is actively pursuing to develop as
new local water supplies. They are known as the Middle Sweetwater River Basin
Groundwater Well, the Otay Mesa Lot 7 Groundwater Well, and the Rancho del Rey
Groundwater Well projects.
Middle Sweetwater River Basin Groundwater Well
The Middle Sweetwater River Basin Groundwater Well is an additional water supply project
that was thoroughly studied and documented in the 1990s. The Middle Sweetwater River
Basin is located within the Sweetwater River watershed and that reach of the river extends
from Sweetwater Reservoir to the upstream Loveland Reservoir. The next step in
development of the Middle Sweetwater River Basin Groundwater Well is the implementation
of a pilot well project. The ultimate objective of the Otay WD is to develop a groundwater
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
48
well production system within the Middle Sweetwater River Basin capable of producing a
sustainable yield of potable water as a local supply.
The purpose of the Middle Sweetwater River Basin Groundwater Well Pilot project is to
identify the feasibility of developing a groundwater resource production system and then
determine and assess any limitations or constraints that may arise. The Middle Sweetwater
River Basin Groundwater Well Pilot Project will accomplish six primary goals:
Update project setting
Update applicable project alternatives analysis
Prepare groundwater well pilot project implementation plan
Construct and test pilot monitoring and extraction wells
Provide recommendations regarding costs and feasibility to develop a groundwater
well production system within the Middle Sweetwater River Basin capable of
producing a sustainable yield of potable water
Prepare groundwater well production project implementation plan and scope of work
The groundwater conjunctive use concept is described as the extraction of the quantity of
water from the groundwater basin that was placed there by customers of the Otay Water
District, Helix Water District, and Padre Dam Municipal Water District by means of their use
of imported treated water that contributed to the overall volume of groundwater within the
basin. An estimated quantity was developed to be approximately 12.5 percent of the total
consumption of the Otay WD customers within that basin, as measured by water meters. In
the 1994-1995 period, the quantity of water that was returned to the groundwater basin by
Otay WD customers was estimated to be 810 acre-feet per year. Currently, that 12.5 percent
quantity could be on the order of 1,000 acre-feet per year. A future scope of work will need
to addresses this concept while considering further development of the groundwater basin as
an additional supply resource. If it is deemed that a Middle Sweetwater River Basin
Groundwater Well Production Project is viable then the consultant will develop and provide a
groundwater well production project implementation plan, cost estimate, and related scope of
work.
Further development of the groundwater basin to enhance the total groundwater production
could be accomplished by the Otay WD by means of additional extraction of water from the
basin that is placed there by means of either injection and/or spreading basins using imported
untreated water as the resource supply. The existing La Mesa Sweetwater Extension Pipeline,
owned by the Water Authority, once converted to an untreated water delivery system, could
be the conveyance system to transport untreated water for groundwater recharge in support of
this conjunctive use concept. These two distinct water resource supply conjunctive use
concepts will be addressed so they may coexist and to allow for their development as separate
phases.
The scope of work to complete Middle Sweetwater River Basin Groundwater Well Pilot
Project consists of many major tasks and is to address the groundwater supply concepts
Otay Water District
Water Supply Assessment and Verification Report

49
outlined above. It is anticipated that the cost for the entire scope of work, will be on the order
of $2,000,000, which includes a contingency and may take up to one and a half years to
complete.
The primary desired outcome of the Middle Sweetwater River Basin Groundwater Well Pilot
Project is for the engineering consultant to determine and make recommendations if it is
financially prudent and physically feasible to develop a Phase I groundwater well production
system within the Middle Sweetwater River Basin capable of producing a sustainable yield of
up to 1,500 ac-ft/yr of potable water for the Otay WD. If it is deemed that a Middle
Sweetwater River Basin Groundwater Well Production Project is viable then the consultant
will develop and provide a groundwater well production project implementation plan and
related scope of work.
Otay Mesa Lot 7 Groundwater Well
In early 2001 the Otay WD was approached by a landowner representative about possible
interest in purchasing an existing well or alternatively, acquiring groundwater supplied from
the well located on Otay Mesa. The landowner, National Enterprises, Inc., reportedly stated
that the well could produce 3,200 acre-feet per year with little or no treatment required prior
to introducing the water into the Otay WD potable water system or alternatively, the recycled
water system. In March 2001 authorization to proceed with testing of the Otay Mesa Lot 7
Groundwater Well was obtained and the Otay WD proceeded with the investigation of this
potential groundwater supply opportunity.
The May 2001 Geoscience Support Services, Inc. completed for the Otay WD the preparation
of a report entitled, “Otay Mesa Lot 7 Well Investigation,” to assess the Otay Mesa Lot 7
Well. The scope of work included a geohydrologic evaluation of the well, analyses of the
water quality samples, management and review of the well video log, and documentation of
well pump testing. The primary findings, as documented in the report, formed the basis of the
following recommendations:
For the existing well to be use as a potable water supply resource, a sanitary seal must
be installed in accordance with the DDW guidelines.
Drawdown in the well must be limited to avoid the possibility of collapsing the casing.
Recover from drawdown from pumping is slow and extraction would need to be
terminated for up to 2 days to allow for groundwater level recovery.
The well water would need to be treated and/or blended with potable water prior to
introduction into the potable water distribution system.
The existing Otay Mesa Lot 7 Well, based upon the above findings, was determined not to be
a reliable municipal supply of potable water and that better water quality and quantity perhaps
could be discovered deeper or at an alternative location within the San Diego Formation.
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project

The Otay WD may still continue to pursue the Otay Mesa groundwater well opportunity with
due consideration of the recommendations of the existing report. Based on the
recommendations of the investigation report, a groundwater well production facility at Otay
Mesa Lot 7 could realistically extract approximately 300 acre-feet per year.
Rancho del Rey Groundwater Well
In 1991, the McMillin Development Company drilled the Rancho del Rey Groundwater Well
to augment grading water supplies for their Rancho del Rey development projects. Although
the well was considered a “good producer,” little was known regarding its water quality and
sustainable yield because the water was used solely for earthwork (i.e. dust control and soil
compaction). The well was drilled to 865 feet, with a finished depth of 830 feet and produced
approximately 400 acre-feet per year of low quality water for four years until its use was
discontinued in April 1995 when the well was no longer needed. McMillin notified the Otay
WD of its intent to sell off the groundwater well asset.
In 1997, the Otay WD purchased an existing 7-inch well and the surrounding property on
Rancho del Rey Parkway from the McMillin Company with the intent to develop it as a
source of potable water. Treatment was required to remove salts and boron, among other
constituents, using reverse osmosis membranes and ion exchange.
In 2000, having received proposals for the design and construction of a reverse osmosis
treatment facility that far exceeded the allocated budget, the Board of Directors instructed
staff to suspend the project until such time as it became economically viable.
In January 2010, citing the rising cost of imported water and the Otay WD's interest in
securing its own water source for long-term supply reliability, the Board authorized Phase 1
for drilling and development of the Rancho del Rey Well.
On March 3, 2010, the Board adopted the Mitigated Negative Declaration for this project and
a Notice of Determination was filed with the County of San Diego on March 5, 2010. In
September 2010, a new 12-inch production well was drilled to a depth of 900 feet through the
groundwater formation and into fractured bedrock. Testing showed the long-term yield of the
new well to be 450 gpm, higher than previous studies had estimated. Separation Processes,
Inc. (SPI), a highly qualified membrane treatment firm, was hired to conduct a detailed
economic feasibility study to confirm that the annualized unit cost of the new water source
was economically competitive with other sources. The economic study estimated the unit
cost of water to be $1, 500 to $2,000 per acre-feet for an alternative that utilizes a seawater
membrane for treating both salts and boron. When compared with the current imported
treated water rate from the Water Authority, and with the knowledge that this rate will
continually increase as MWD and the Water Authority raise their rates, the Rancho del Rey
Well project appears to be economically viable.
The Otay WD is continuing to pursue the Rancho del Rey groundwater well opportunity with
due consideration of the recommendations of the existing reports and plans to develop a
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
51
groundwater well production facility to extract approximately 500 acre-feet per year. For
water planning purposes, production of groundwater from the Rancho del Rey well is
considered “additional planned” for local supplies.
6.3.1.4 Otay Water District Desalination Project
The Otay WD is currently investigating the feasibility of purchasing desalinated water from a
seawater reverse osmosis plant that is planned to be located in Rosarito, Mexico, known as the
Otay Mesa Desalinated Water Conveyance System (Desalination) project. The treatment
facility is intended to be designed, constructed, and operated in Mexico by a third party. The
Otay WD’s draft Desalination Feasibility Study, prepared in 2008, discusses the likely issues
to be considered in terms of water treatment and monitoring, potential conveyance options
within the United States from the international border to potential delivery points, and
environmental, institutional, and permitting considerations for the Otay WD to import the
Desalination project product water as a new local water supply resource.
While the treatment facility for the Desalination project will not be designed or operated by
the Otay WD , it is important that the Otay WD maintain involvement with the planning,
design, and construction of the facility to ensure that the implemented processes provide a
product water of acceptable quality for distribution and use within the Otay WD’s system as
well as in other regional agencies’ systems that may use the product water, i.e. City of San
Diego, the Water Authority, etc. A seawater reverse osmosis treatment plant removes
constituents of concern from the seawater, producing a water quality that far exceeds
established United States and California drinking water regulations for most parameters,
however, a two-pass treatment system may be required to meet acceptable concentrations of
boron and chlorides, similar to the levels seen within the existing Otay WD supply sources.
The Desalination Feasibility Study addresses product water quality that is considered
acceptable for public health and distribution.
The Otay WD, or any other potential participating agencies, will be required to get approval
from the DDW in order to use the desalinated seawater as a water source. Several alternative
approaches are identified for getting this approval. These alternatives vary in their cost and
their likelihood of meeting DDW approval.
The Rosarito Desalination Facility Conveyance and Disinfection System Project report
addresses two supply targets for the desalinated water (i.e. local and regional). The local
alternative assumes that only Otay WD would participate and receive desalinated water, while
the regional alternative assumes that other regional and/or local agencies would also
participate in the Rosarito project.
On November 3, 2010, the Otay WD authorized the General Manager to enter into an
agreement with AECOM for the engineering design, environmental documentation, and the
permitting for the construction of the conveyance pipeline, pump station, and disinfection
Otay Water District
Water Supply Assessment and Verification Report

52
facility to be constructed within the Otay WD. The supply target is assumed to be 50 mgd
while the ultimate capacity of the plant will be 100 mgd.
The Otay WD is proceeding with negotiations among the parties.
6.3.2 Otay Water District Capital Improvement Program
The Otay WD plans, designs, constructs, and operates water system facilities to acquire
sufficient supplies and to meet projected ultimate demands placed upon the potable and recycled
water systems. In addition, the Otay WD forecasts needs and plans for water supply
requirements to meet projected demands at ultimate build out. The necessary water facilities and
water supply projects are implemented and constructed when development activities proceed and
require service to achieve timely and adequate cost effective water service.
New water facilities that are required to accommodate the forecasted growth within the entire
Otay WD service area are defined and described within the Otay Water District WFMP Update.
These facilities are incorporated into the annual Otay WD Six Year Capital Improvement
Program (CIP) for implementation when required to support development activities. As major
development plans are formulated and proceed through the land use jurisdictional agency
approval processes, Otay WD prepares water system requirements specifically for the proposed
development project consistent with the Otay WD WFMP Update. These requirements
document, define, and describe all the potable water and recycled water system facilities to be
constructed to provide an acceptable and adequate level of service to the proposed land uses, as
well as the financial responsibility of the facilities required for service. The Otay WD funds the
facilities identified as CIP projects. Established water meter capacity fees and user rates are
collected to fund the CIP project facilities. The developer funds all other required water system
facilities to provide water service to their project.
Section 7 – Conclusion: Availability of Sufficient Supplies
The Otay Ranch Village 14 and Planning Areas 16/19 Project is currently located within the
jurisdictions of the Otay WD, Water Authority, and MWD. To obtain permanent imported
water supply service, land areas are required to be within the jurisdictions of the Otay WD,
Water Authority, and MWD to utilize imported water supply.
The Water Authority and MWD have an established process that ensures supplies are being
planned to meet future growth. Any annexations and revisions to established land use plans
are captured in the SANDAG updated forecasts for land use planning, demographics, and
economic projections. SANDAG serves as the regional, intergovernmental planning agency
that develops and provides forecast information. The Water Authority and MWD update their
demand forecasts and supply needs based on the most recent SANDAG forecast
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Village 14 and Planning Areas 16/19 Project
53
approximately every five years to coincide with preparation of their urban water management
plans. Prior to the next forecast update, local jurisdictions with land use authority may require
water supply assessment and/or verification reports for proposed land developments that are
not within the Otay WD, Water Authority, or MWD jurisdictions (i.e. pending or proposed
annexations) or that have revised land use plans with either lower or higher development
intensities than reflected in the existing growth forecasts. Proposed land areas with pending
or proposed annexations, or revised land use plans, typically result in creating higher demand
and supply requirements than previously anticipated. The Otay WD, Water Authority, and
MWD next demand forecast and supply requirements and associated planning documents
would then capture any increase or decrease in demands and required supplies as a result of
annexations or revised land use planning decisions.
MWD’s IRP identifies a mix of resources (imported and local) that, when implemented, will
provide 100 percent reliability for full-service demands through the attainment of regional
targets set for conservation, local supplies, State Water Project supplies, Colorado River
supplies, groundwater banking, and water transfers. The 2015 IRP Update describes an
adaptive management strategy to protect the region from future supply shortages. This
adaptive management strategy has five components: achieve additional conservation savings,
develop additional local water supplies, maintain Colorado River Aqueduct supplies, stabilize
State Water Project supplies, and maximize the effectiveness of storage and transfer. MWD’s
2015 IRP has a plan for identifying and implementing additional resources that expand the
ability for MWD to meet future changes and challenges as necessary to ensure future
reliability of supplies. The proper management of these resources help to ensure that the
southern California region, including San Diego County, will have adequate water supplies to
meet long-term future demands.
MWD adopted its 2015 UWMP, in accordance with state law, on May 9, 2016. The resource
targets included in the preceding 2015 IRP Update serve as the foundation for the planning
assumptions used in the 2015 UWMP. MWD’s 2015 UWMP contains a water supply
reliability assessment that includes a detailed evaluation of the supplies necessary to meet
demands over a 20-year period in average, single dry year, and multiple dry year periods. As
part of this process, MWD also uses the current SANDAG regional growth forecast in
calculating regional water demands for the Water Authority’s service area.
As stated in MWD’s 2015 UWMP, the plan may be used as a source document for meeting
the requirements of SB 610 and SB 221 until the next scheduled update is completed in 5
years (2020). The 2015 UWMP includes a “Justifications for Supply Projections” in
Appendix A.3, that provides detailed documentation of the planning, legal, financial, and
regulatory basis for including each source of supply in the plan.
In the Findings Section of the Executive Summary (Page ES-5) of their 2015 UWMP, MWD
states that MWD has supply capacities that would be sufficient to meet expected demands
from 2020 through 2040 under the single dry-year and multiple dry-year conditions. MWD
has plans for supply implementation and continued development of a diversified resource mix
Otay Water District
Water Supply Assessment and Verification Report

54
including programs in the Colorado River Aqueduct, State Water Project, Central Valley
Transfers, local resource projects, and in-region storage that enables the region to meet its
water supply needs. MWD’s 2015 UWMP identifies potential reserve supplies in the supply
capability analysis (Tables 2-4, 2-5 and 2-6), which could be available to meet the
unanticipated demands.
The County Water Authority Act, Section 5 subdivision 11, states that the Water Authority
“as far as practicable, shall provide each of its member agencies with adequate supplies of
water to meet their expanding and increasing needs.”
As part of preparation of a written water supply assessment report, an agency’s shortage
contingency analysis should be considered in determining sufficiency of supply. Section 11
of the Water Authority’s 2015 Updated UWMP contains a detailed shortage contingency
analysis that addresses a regional catastrophic shortage situation and drought management.
The analysis demonstrates that the Water Authority and its member agencies, through the
Emergency Response Plan, Emergency Storage Project, Carlsbad Desalination Project, and
Drought Management Plan (DMP) are taking actions to prepare for and appropriately handle
an interruption of water supplies. The DMP, adopted in May 2006, provides the Water
Authority and its member agencies with a series of potential actions to take when faced with a
shortage of imported water supplies from MWD due to prolonged drought or other supply
shortfall conditions. The actions will help the region avoid or minimize the impacts of
shortages and ensure an equitable allocation of supplies.
The WSA&V Report identifies and describes the processes by which water demand
projections for the proposed Otay Ranch Village 14 and Planning Areas 16/19 Project will be
fully included in the water demand and supply forecasts of the Urban Water Management
Plans and other water resources planning documents of the Water Authority and MWD.
Water supplies necessary to serve the demands of the proposed Otay Ranch Village 14 and
Planning Areas 16/19 Project, along with existing and other projected future users, as well as
the actions necessary and status to develop these supplies, have been identified in the Otay
Ranch Village 14 and Planning Areas 16/19 Project WSA&V Report and will be included in
the future water supply planning documents of the Water Authority and MWD.
This WSA&V Report includes, among other information, an identification of existing water
supply entitlements, water rights, water service contracts, water supply projects, or
agreements relevant to the identified water supply needs for the proposed Otay Ranch Village
14 and Planning Areas 16/19 Project. This WSA Report assesses, demonstrates, and
documents 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 and multiple dry years to
meet the projected demand of the proposed Otay Ranch Village 14 and Planning Areas 16/19
Project and the existing and other planned development projects to be served by the Otay
WD.

Table 5 presents the forecasted balance of water demands and required supplies for the Otay
WD service area under average or normal year conditions. The total actual demand for FY
2015 was 30,271 acre feet. The demand for FY 2015 is 2,999 acre feet lower than the
demand in FY 2010 of 33,270 acre feet. The drop in demand is a result of the unit price of
water, the conservation efforts of users as a result of the prolonged drought, and the economy.
Table 5 presents the forecasted balance of water demands and supplies for the Otay WD
service area under single dry year conditions. Table 6 presents the forecasted balance of
water demands and supplies for the Otay WD service area under multiple dry year conditions
for the three year period ending in 2019. The multiple dry year conditions for periods ending
in 2025, 2030, and 2035 are provided in the Otay Water District 2015 UWMP. The projected
potable demand and supply requirements shown the Tables 5 and 6 are from the Otay WD
2015 UWMP. Hot, dry weather may generate urban water demands that are about 6.4 percent
greater than normal. This percentage was utilized to generate the dry year demands shown in
Table 6. The recycled water supplies are assumed to experience no reduction in a dry year.

District Demand totals with SBX7-7 conservation target achievement plus single dry year increase as shown. The
Water Authority could implement its DMP. In this instances, the Water Authority may have to allocate supply shortages
based on it equitable allocation methodology in its DMP.
Dry year demands assumed to generate a 7% increase in demand over normal conditions for a
single dry year. For multiple dry years an 8% increase in demand over normal conditions is
projected in the first year, 14% in the second year and 21% increase is projected in the third
year in addition to new demand growth.
In evaluating the availability of sufficient water supply, the Otay Ranch Village 14 and
Planning Areas 16/19 Project development proponents will be required to participate in the
development of alternative water supply project(s). This can be achieved through payment of
the New Water Supply Fee adopted by the Otay WD Board in May 2010. These water supply
projects are in addition to those identified as sustainable supplies in the current Water
Authority and MWD UWMP, IRP, Master Plans, and other planning documents. These new
water supply projects are in response to the regional water supply issues related to
climatological, environmental, legal, and other challenges that impact water source supply
conditions, such as the court rulings regarding the Sacramento-San Joaquin Delta and the
current ongoing western states drought conditions. These new additional water supply
projects are not currently developed and are in various stages of the planning process. The
Otay WD water supply development program includes but is not limited to projects such as
the Middle Sweetwater River Basin Groundwater Well project, the North District Recycled
Water Supply Concept, the Otay WD Desalination project, and the Rancho del Rey
Groundwater Well project. The Water Authority and MWD’s next forecasts and supply
planning documents would capture any increase in water supplies resulting from any new
water resources developed by the Otay WD.
The Otay WD acknowledges the ever-present challenge of balancing water supply with
demand and the inherent need to possess a flexible and adaptable water supply
implementation strategy that can be relied upon during normal and dry weather conditions.
The responsible regional water supply agencies have and will continue to adapt their resource

plans and strategies to meet climate, environmental, and legal challenges so that they may
continue to provide water supplies to their service areas. The regional water suppliers along
with Otay WD fully intend to maintain sufficient reliable supplies through the 20-year
planning horizon under normal, single, and multiple dry year conditions to meet projected
demand of the Otay Ranch Village 14 and Planning Areas 16/19 Project, along with existing
and other planned development projects within the Otay WD service area.
This WSA&V Report assesses, demonstrates, and documents that sufficient water supplies are
planned for and are intended to be acquired, as well as the actions necessary and status to
develop these supplies, to meet projected water demands of the Otay Ranch Village 14 and
Planning Areas 16/19 Project as well as existing and other reasonably foreseeable planned
development projects within the Otay WD for a 20-year planning horizon, in normal and in
single and multiple dry years.

SUBJECT: Informational Item – Otay Ranch Village 3 – Request for
Information Concerning Methane and VOC at Village 3 and Otay
Water District’s Course of Action
GENERAL MANAGER’S RECOMMENDATION:
No recommendation. This is an informational item only.
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To update the Otay Water District (District) Board regarding the
District’s request for information concerning methane and volatile
organic compounds (VOCs) at Otay Ranch Village 3 (Village 3) and the
District’s course of action.
ANALYSIS:
Between February 2017 and April 2017, the District entered into four
(4) construction agreements with HomeFed Village III Master, LLC, a
Delaware limited liability company (Developer), to construct both
potable and recycled water facilities for Otay Ranch Village 3. These
developer funded construction agreements total $8.2 million. The
2
Developer, as part of the agreements, has provided bonding to the
District for the construction of the facilities.
Village 3 is located along the future extension of Heritage Road south
of Otay Ranch Village 2 (Village 2), east of the Otay Landfill, and
north of the future extension of Main Street in the City of Chula
Vista, as shown on Exhibit A. Village 3 proposes to construct
approximately 1,265 dwelling units that consists of single-family
residential, single-family high density residential, multi-family
residential, and commercial/mixed use. The development land use also
includes office, industrial, a school, parks, and private open space.
With the construction agreements in place, the Developer has
constructed approximately 25,000 linear feet of distribution main to
date. This main has not been tied directly into the District’s
system.
District staff has been notified by the Developer of the presence of
methane and VOCs within the Village 3 development. The following
summarizes the chronology of events to date:
On August 3, 2017, District staff contacted the Developer and
requested feedback to validate existing soils conditions within the
Village 3 development prior to the approval of plans for additional
potable water facilities within Village 3. Staff requested that the
Developer provide visibility to any known issues.
On October 18, 2017 the Developer met with District staff to discuss a
proposed design for a Village 3 pressure reducing station (PRS).
During the meeting the Developer stated that the proposed design was
being modified to address methane and VOCs found within the Village 3
development. District staff noted that the presence of methane and
VOCs represent a changed condition to the approved plans. District
staff requested formal notification from the Developer and a report of
the findings and mitigation strategies planned for the water
infrastructure. District staff reached out to the City of Chula
Vista. City staff verified that the Developer is implementing methane
venting systems on the structures that are being constructed in
Village 3.
On October 24, 2017, the District received a public inquiry from a
potential Village 3 home buyer regarding concerns over “VOCs and
methane found in the soil and perched groundwater.” District staff
immediately communicated the inquiry to the Developer and requested
that the Developer provide all information available.
3
On November 2, 2017, the District sent the Developer a letter
requesting information concerning methane and VOCs at Village 3 and
communicated the District’s course of action (refer to Exhibit B).
Within the letter the District noted the following course of action:
1. The District again demands the immediate provision of all reports
and documents relating to the site conditions at or around
Village 3 specifically including, but not limited to, methane
and/or VOCs;
2. Following receipt of these reports and documents, the District
will need time to perform a thorough analysis of the reports and
documents and reserves the right to request additional studies
and research of the site conditions and any proposed mitigation
plans or efforts relating to the methane and/or VOCs;
3. Effective immediately, the District is suspending all approvals
for projects within Village 3 until we understand the full extent
of the site conditions and the mitigation measures for the water
facilities that will be needed to address the site conditions;
4. No water meters will be set within Village 3 until District
approved mitigation for the site conditions has been constructed;
5. HomeFed shall cover all costs associated with the investigation
and remediation of the site conditions.
On November 3, 2017, the Developer transmitted to the District a Site
Assessment and Human Health Vapor Risk Assessment Report for Village 3
dated August 17, 2017. In addition, the Developer provided a response
to the October 24, 2017 public inquiry. In response to the
information provided by the Developer, the District retained
consultant expertise from the District’s As-Needed contract with Ninyo
& Moore to assist in the review and evaluation of the information
provided by the Developer.
On November 8, 2017, the Developer met with District staff to provide
an overview of the transmitted information. During the meeting, the
District expressed concerns in the following areas:
Reports provided by the Developer do not provide an ultimate
projection of the Village 3 site conditions with respect to
methane and VOCs. The District will need this information to
evaluate what level of mitigation measures are needed;
Certification that the water facilities installed to date by the
Developer are approved for use under the current known site
4
conditions and the ultimate projection of the Village 3 site
conditions will be required;
Water facility methane and VOC mitigation measures may be
required to maintain and operate the water system under the
ultimate Village 3 site conditions.
On November 20, 2017, the Developer requested a meeting with the
District. During that meeting, the Developer requested that the
District reverse its decision to suspend all approvals including the
setting of water meters. District staff noted that the Developer has
not provided information on the suitability of the water facility
materials (including, but not limited to, gaskets that are used in the
pipelines and appurtenances). Additionally, the Developer has not
provided a plan that addresses any long-term mitigation requirements
associated with operating and maintaining the water facilities for
Village 3.
Potable water for Village 3 will be imported and supplied from the San
Diego County Water Authority. The water is planned to be delivered
through water pipeline infrastructure constructed by the Village 2
development which is located immediately north of Village 3. On
November 21, 2017, the developer for Village 2 verbally expressed
concerns to District staff regarding the tie in of Village 3
infrastructure to the Village 2 infrastructure. The District’s
understanding is that the Village 2 developer does not wish to allow
the tie in until the Village 3 methane and VOC issues are understood
and resolved.
It is staff’s understanding that the Village 3 Developer is working
towards assembling the needed information and certifications required
to move the project forward. District staff is researching agency
guidelines, both in the State of California and nationally, for the
construction of water facilities in areas of methane and VOCs.
District staff is also reaching out to the project’s material
suppliers regarding the suitability of their materials in methane and
VOC environments.
The Developer has communicated with the District that their builder
partners currently have contracts for the sale of approximately two
hundred homes in Village 3. The District anticipates that meters that
total seventy Equivalent Dwelling Units (EDUs) will be purchased and
set once the methane and VOCs issue is resolved. Meter sets for
future EDUs beyond the seventy mentioned above are pending the
Developer establishing a secondary feed of water to Village 3 to
support fire flow requirements for the development.

HomeFed Corporation
1903 Wright Place,Suite 220
Carlsbad,Ca 92008
SUBJECT:Request for Information Concerning Methane and VOC at Village 3
and Otay Water District's Course of Action
Dear Mr.Smith:
This letter is intended to recount specific concerns and to set forth the Otay Water
District's ("District")planned course of action relating to the Village 3 Development. As
you may be aware, the District is a local government organized under the provisions of
the Municipal Water District Act of 1911 to provide water and sewer service to the
communities of eastern Otay Mesa,including eastern Chula Vista.
Relating to this mandate, the District endeavors to work with developers to ensure the
safe,timely,and efficient installation of piping and facilities necessary to deliver water
and sewer services to developments within the District's service area.Typically,withthe
cooperation ofdevelopers, the District is able to address site-specific issues,which may
arise during the development and construction process.Unfortunately,the District has
received minimal cooperation from you and HomeFed regarding the requests for
information relating to the Village 3 development.
The District is extremely concerned about the presence of methane gas and/or VOC
hydrocarbons at the Village 3 development.Thisconcern began to manifeston orabout
August2, 2017, when the District contacted you regarding the Village 3-Heritage Road
Pressure Reducing Station Plans.Specifically,the District was seeking additional
information to follow up on information it had received from independent sources that
intimated ongoing issues involving methane gas and/or VOCs within the Village 3
development.
On multiple additional occasions, the District has contacted you and requested
information relating to Village 3,the possible presence ofmethane gas and/or VOCs,and
any existing plansorstudies related thereto.Specifically,on August 3,2017,Dan Martin
the District's Engineering Manager, sent an e-mail and spoke with you regarding the
Village 3 Heritage Road Pressure Reducing Station Plans and Agreement.Mr.Martin
requested feedback from you and HomeFed to validate existing soil conditions at the
Mr.Curt Smith
Request for Information Concerning Methane and VOC at Village 3 and Otay Water
District's Course of Action
November 2,2017

facility location and along Heritage Road,and advised you that this information was
necessary to evaluate whether any change in plans was necessary as a result of the site
conditions and possible presence of methane and/or VOCs. You responded that
HomeFed had not yet completed their assessment of the site, but agreed that the District
should hold back on approving the agreement until HomeFed finalizes their assessment
and presented the information to the District for consideration.The District has not
received an assessment and HomeFed has not presented information.
On October 18,2017,Dan Martin,Brandon DiPietro,Bob Kennedy,Jon Chambers,Jake
Vaclavek,Oscar Ramirez,and Jose Martinez—employees of the District—met with you,
Alisa Vialpando (from Hunsaker),Brian Canaris (from Terra Development),and Chris
Conahan (from Methane Specialists)to discuss the Village 3 PRS and methaneA/OCs
found within Village 3. At the meeting,methane mitigation measures for the Pressure
Reducing Station Plans were presented by Mr.Conahan.You passed around an 8-1/4"x
11"map with information about the methane encountered on site at Village 3 and you
disclosed that VOCs were encountered on site near Heritage Road and Energy Way.
Mr.Martin advised you that the District had received no information from HomeFed
concerning specific findings relating to methane found within Village 3.Mr.Martin again
requested that HomeFed provide the District with their findings, in writing,as well as a
comprehensive study of the area and plans that incorporate mitigation measures for
planned water facilities for the District's consideration.Mr.Martin also informed those
present that the District will need to retain expert(s) to review the information once
HomeFed provides same.At the end of the meeting, you took the map with you.You
indicated that you would provide the information,but you have not done so.
On or about October 24,2017,the District received a public inquiry from an individual
identifying himself as a potential buyer of a home within Village 3. This public inquiry
specifically raised concerns over "VOCs and methane found in the soil and perched
groundwater."In response, the District again contacted you seeking all information that
is currently available to HomeFed relating to the methane and/or VOC issues and any
future information,which may become available. To date, the District has not received
any such information.
This lack of disclosure and communication is not only unprofessional,but has now placed
the District in a precarious position. Generally, the information regarding methane gas
and/or VOCs is essential,as these compounds can impact pipes and facilities, which will
become the District's responsibility upon acceptance of the Developer work.More
specifically,the District had previously communicated that this information is needed as
it may influence the design of current or future pipelines,routing of lines,facilities,
construction timelines,and/or types of materials used at or around Village 3. Due to
HomeFed's lack of cooperation and refusal to timely provide the information requested,
the District shall proceed as follows:

Request for Information Concerning Methane and VOC at Village 3 and Otay Water
District's Course of Action
November 2,2017
Page 3 of 3.
1.The District again demands the immediate provision of all reports and documents
relating to the site conditions at or around Village 3 specifically including, but not
limited to,methane and/or VOCs;
2. Following receipt of these reports and documents,the District will need time to
perform a thorough analysis of the reports and documents and reserves the right
to request additional studies and research of the site conditions and any proposed
mitigation plans or efforts relating to the methane and/or VOCs;
3. Effective immediately,the District is suspending all approvals for projects within
Village 3 until we understand the full extent ofthe site conditions and the mitigation
measures for the water facilities that will be needed to address the site conditions;
4. No water meters will be set within Village 3 until District approved mitigation for the
site conditions has been constructed;
5.HomeFed shall cover all costs associated with the investigation and remediation
of the site conditions.
We look forward to receiving pertinent documents as well as the necessary cooperation
from you and HomeFed, so that we can work toward the completion of the Village 3
development.Please contact Dan Martin,P.E., Engineering Manager at (619)670-2243
or via e-mail at dan.martin(a)otavwater.gov,ifyou have any questions or wish to discuss
the District's concerns further.

SUBJECT: Informational Item – Otay Ranch Village 2 East, Otay Ranch
Village 2 Heritage Road, and Otay Ranch Village 2 North
Projects; 20-Inch Recycled Water Main – Outside Diameter Non-
Conformance
GENERAL MANAGER’S RECOMMENDATION:
No recommendation. This is an informational item only.
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To update the Otay Water District Board (Board) about a non-
conformance issue associated with the 20—inch recycled water main
constructed as part of the Otay Ranch Village 2 East, Otay Ranch
Village 2 Heritage Road, and Otay Ranch Village 2 North developer
Projects.
ANALYSIS:
Between November 2006 and March 2007, the District entered into three
construction agreements with Otay Project, L.P. (Developer) to
construct both potable and recycled water facilities for Otay Ranch
Village 2. Each of the three agreements include the construction of a
portion of 20-inch recycled water transmission main. In excess of
2
7,500 linear feet of the 20-inch recycled water main was constructed
and placed into service prior to the downturn in the housing economy.
The 20-inch recycled water main constructed under the developer
construction agreements is located in Heritage Road, Santa Victoria
Road, and Santa Venetia Street, as shown in Exhibit A. The
construction agreements and associated bonding that includes the 20-
inch recycled water main are still active pending completion and
acceptance of the work.
During the 2017 calendar year, the Developer had requested additional
lateral services constructed on the 20-inch recycled water main
located in Santa Venetia Street. During the construction of these
services, it was discovered by District Inspection staff, that the
outside diameter of the 20-inch main exceeded the AWWA C-900-16, C-
905-97, and the pipe manufacturer’s tolerances, raising District
concerns regarding the longevity and integrity of the pipe. Saddles
with a larger working range were required to perform the additional
lateral services. The District brought the concern to the Developer,
the Developer’s construction contractor, and the pipe manufacturer (JM
Eagle Pipe) and additional potholing along the main for the purposes
of measuring the pipe diameter was performed by the Developer.
The potholing and pipe diameter measurements by the Developer and
manufacturer have verified additional locations where the outside
diameter of the 20-inch main exceeds the pipe manufacturer’s
tolerances. The pipe diameter measurements also indicated that the
20-inch main was constrained in areas where saddles were installed as
part of the original installation. This may be an indication that
possible dimensional creep of the pipe has taken place since
installation. Staff has sent a letter to the Developer (Exhibit B) to
provide notification to the Developer that the non-conforming pipe
poses a long-term risk of failure. Staff also notified the Developer
that contract acceptance for the projects is pending remediation
measures and/or replacement of the pipe by Otay Project, L.P. The
District has requested that Otay Project, L.P. develop a plan to
resolve this issue.

Projects;20-Inch Recycled Main -Outside Diameter Non-Conformance
Dear Mr.Lee:
As you are aware,the Otay Ranch Village 2 development by Otay Project,L.P.has
been under construction with the Otay Water District ("District")since 2006.Three
projects within Otay Ranch Village 2,which are identified above,include the
construction of a 20-inch recycled water main.
On February 15,2017,District staff met with representatives of Otay Project L.P.,Cass
Construction,and JM Eagle to review locations where the 20-inch recycled water main
pipe was found to exceed the allowable outer dimension tolerances listed per AWWA C-
900-16 and C-905-97.The maximum outer diameter for this size and class of pipe is
21.625 inches per AWWA.As presented during the meeting,the outside diameter
measurements documented by the District during developer requested wet taps along
the 20-inch main performed in January 2017 were found to be in excess of 21.72
inches.
As a result of the February 15,2017 meeting,JM Eagle,in cooperation with Cass
Construction and Otay Project L.P.,initiated independent in-situ dimensional
inspections at fourteen points within five locations along the length of the 20-inch
recycled water main constructed under the subject projects.Those inspections were
performed during April 2017.Reported findings of those inspections documented
outside diameter measurements ranging from 21.625 inches to 21.712 inches.All but
two of the in-situ dimensional inspections,conducted under JM Eagle's direction,were
found to be in excess of the allowable outer dimension tolerances listed per AWWA.
This was documented in the July 7,2017 Project Report produced by PSILab,Inc.In
Mr.Nick Lee
Otay Ranch Village 2 East (D0261-010178),Otay Ranch Village 2 Heritage Road (D0261-

Page 2 of 2.
addition,the PSILab,Inc.report documented the observation of audible "creaking"
noises coming from the pipeline while being operated within rated operating pressures.
The PSILab,Inc.Project Report indicates that eighty-six percent (12 out of 14)of the
points exposed and measured as part of the in-situ dimensional inspections are in
excess of the allowable outer dimension tolerances listed per AVVWA.This non-
conforming pipe poses a long-term risk of failure and may have a shortened life span.It
is not clear how this non-conforming pipe will affect the pipeline bells and service
saddles that were installed as part of the planned distribution system.As a result,
contract acceptance for the subject projects is pending remediation measures and/or
replacement of the pipe by Otay Project L.P.The District is requesting that Otay Project
L.P.develop a plan to resolve this issue.
Please do not hesitate to let me know if there are any questions.I can be reached at

COMMITTEE ACTION:
No committee action.
PURPOSE:
To present to the Board of Directors (Board) information gathered and
prepared in evaluating seismic risk studies and the potential risks
from a seismic event.

Overview
All of the potable water the District receives is imported water supplied by the State
Water Project (SWP) and the Colorado River Aqueduct (CRA) purchased through the
Municipal Water District of Southern California (MWD) and San Diego County Water
Authority (Water Authority). This dependence on imported water poses challenges to
meet water demands after an emergency seismic event. At the request of the Board,
staff have collected seismic risk studies on water facilities to provide an overview of the
risks from a seismic event.
State Water Project
The SWP facilities were built in the 1960s, however, over the last fifty years, the design
and construction standards have improved in the area of seismic design requirements.
Seismic loading on these facilities is considered to have the potential to do the most
damage to the SWP facilities, which could interrupt water supplies to California. The
September 2012 Seismic Loading Criteria Report, prepared by the California
Department of Water Resources (DWR), is a guideline in selecting appropriate seismic
loading criteria for the design and evaluation for a wide variety of SWP facilities,
including dams, canals, pipelines, tunnels, check structures, bridges, buildings, pumping
and power plants, and utility overcrossings. This report also offers an initial seismic
hazard determination of SWP facilities.
In August 2015, DWR. MWD and Los Angeles Department of Water and Power formed
the Seismic Resilience Water Supply Task Force (SRWSTF) to improve the seismic
resilience of imported water supplies to Southern California and to collaborate on
studies and mitigation measures that address the vulnerabilities of aqueducts that cross
faults. With this multiagency cooperation, they will be revisiting assumptions regarding
potential outages from seismic events, establish a common understanding about
individual aqueduct vulnerability assessments and projected damage scenarios.
MWD Facilities
Portions of the Colorado River Aqueduct are located near earthquake faults including
the San Andreas Fault. The five pumping plants on the Colorado River Aqueduct have
been buttressed to better withstand seismic events. Other components of the Colorado
River Aqueduct are measured for any necessary rehabilitation and repair. Supplies are
dispersed throughout MWD’s service area, and a six-month reserve supply of water
normally held in local storage provides reasonable assurances of continuing water
supplies following seismic events. MWD has developed an emergency plan that calls
for specific levels of response appropriate to an earthquake magnitude and location.
However, no assurance can be made that a significant seismic event would not cause
damage to project structures, which could, thereby, interrupt the supply of water from
the Colorado River Aqueduct.
2
MWD has adopted a Seismic Resiliency Strategy and has invested $257 million in this
effort over the last 10 years. MWD’s Emergency Response Program includes a
dedicated pipe manufacture facility in La Verne with materials and dedicated crew to
fabricate pipe up to 20 feet in diameter. They have also prequalified contractors that
can mobilize in an emergency. They estimate up to 6 large diameter repairs can be
made in one week. Two by MWD’s staff and 4 by hired contractors. Annually MWD’s
Board will received a report on this program.
Water Authority Vulnerability Report
The Water Authority facilities are designed to withstand earthquakes with minimal
damage. Earthquake loads have been taken into consideration in the design of project
structures such as pumping plants and hydroelectric plants. All known faults are
crossed by pipelines at very shallow depths to facilitate repair in case of damage from
movement along a fault. To date, no Water Authority facilities have suffered any
material earthquake damage. In 1993, the Water Authority issued a vulnerability report
entitled, Emergency Storage Project SDCWA Aqueducts Repair Time Estimate (see
Attachment A), which estimated the degree of damage to pipelines and the amount of
time required to restore services after a natural disaster, particularly earthquakes.
The Water Authority has since implemented a number of procedures to respond to
emergency events, including the Integrated Contingency Plan (ICP) and the Emergency
Storage Program (ESP), both of which were developed to protect public health and
safety. The Water Authority’s ICP and ESP provide actions to be taken in the event of
an earthquake or power outage. The ESP was designed to allow continued water
service to its member agencies at a 75 percent level of service or better up to six
months, in the event of a complete interruption of water deliveries from MWD.
A recommendation of the Water Authority’s 2013 Master Plan Update included a
System Vulnerability Assessment focusing on structure integrity of critical facilities. This
study will focus on facilities with limited condition assessment data or that are not fully
covered by the Asset Management Program. At the August 24, 2017 Board meeting,
the Board authorized the General Manager for the Water Authority to award a
professional services contract to Kleinfelder, Inc., to complete the seismic vulnerability
assessment.
The City of San Diego Seismic Assessment
The City of San Diego with G&E Engineering Systems prepared an abstract entitled,
Seismic Assessment of the San Diego Water System. This report identified faults,
landslide, and liquefaction prone areas of the City and estimated the length of pipe in
each hazard zone. Their fragility model identified the bulk of damage is due to
liquefaction, followed by landslides. They also identified the number of pump stations
3
expected to lose power from SDG&E and recommended portable power is needed
where fire threat is high following an earthquake.
County of San Diego Multi-jurisdictional Plan
The federal Disaster Mitigation Act of 2000 requires all local governments to create a
disaster plan in order to qualify for hazard mitigation funding. San Diego County Multi-
jurisdictional Hazard Mitigation Plan was one of the first in the State to tackle this
planning effort on a region-wide basis and was last revised in 2010. The plan is
currently being reviewed and revised to reflect changes to both the hazards threatening
San Diego as well as the programs in place to minimize or eliminate those hazards.
This document also includes maps identifying earthquake, liquefaction, and rain induced
landslide areas of the county.
San Diego – Tijuana Metropolitan Area Planning Scenario
An October 1991 study by the State of California Department of Conservation Division
of Mines and Geology entitled, “Planning Scenario for a Major Earthquake, San Diego-
Tijuana Metropolitan Area,” presented a regional perspective on the plausible
consequences of credible damage from an earthquake of magnitude 6.8 on the Silver
Strand fault south of downtown San Diego. This report notes historic seismic activity
within the metropolitan area has been limited: damaging earthquakes occurred only in
1800, 1862, 1983, 1985, and 1986. None of these earthquakes produced serious
damage.
This report notes it is anticipated that all water systems within the region will suffer
some damage. In areas of intense shaking and/or ground failure, two to four main
breaks in every residential block will be common where cast iron or asbestos cement
pipe is used. There were some reports of broken pipes following the October 28, 1986
earthquake in southeast San Diego (M4.1). The report recommends restoration of
water mains begins at the lowest topographic point, progressing uphill so that broken
sewers in the same areas do not contaminate still broken water lines. The extent of
damage to the distribution system may not be known until water pressure is restored
and leaks identified. For this reason, it could take weeks to totally repair damage in the
densely populated, heavily damaged areas.
Other Water Agencies
Sweetwater Authority
Several adjacent agencies were contacted to identify seismic studies on infrastructure.
In 2006, Sweetwater Authority had GEI Consultants prepare a study on a tank built in
1950. Their study confirmed that this tank would experience significant bottom plate
uplift, but suggest that it would be capable of resisting the specified earthquake loading
4
without experiencing global sliding and overturning/overstressing of its shell. However,
uplift would be significant enough to potentially shear off the inlet/outlet and bottom
drain piping, resulting in probable loss of the contained water. Newer AWWA D 100-96
standards would require a new tank of similar dimensional characteristics to be
anchored or alternative procedures to be implemented (e.g., bottom plate thickening).
Considering the age of this tank and the performance requirements outlined by
Sweetwater Authority, they recommended adding flexibility to the attached piping and
relocating the bottom drain outlet, which may provide a cost-effective way to maintain
safe storage under earthquake shaking. An update on their current practices was
requested, but to date no new information has been received.
Helix Water District
Helix Water District provided a report dated November 1988 entitled, Seismic Review of
Storage Facilities, which provided a conceptual method of repair and an estimate of
construction costs for 20 tanks (37 MG total). The fifteen page report used seismic
evaluation criteria available at the time from Uniform Building Code and AWWA. Since
this report, seven tanks (5.7 MG) have been replaced or retired. The total rudimentary
cost for the retrofits for the seven tanks was estimated to be $1,114,900 (an average
cost of $196,000/MG).
Nine tanks (23 MG) had some seismic modification made that ranged from adding a
flexible connection to adding thickening bottom plates and foundation anchors. The
total rudimentary cost for the retrofits for the nine tanks was estimated to be $547,700
(an average cost of $23,800/MG).
Padre Dam MWD
Padre Dam deferred questions about their reservoirs to their consultant, Kleinfelder,
Inc., who has not provided any information to date on what they have recommended.
Padre Dam does have a CIP referred to as the “Five Reservoirs Retrofit Program.” The
plan included the replacement of old wood roofs on their in ground reservoirs with new
aluminum covers, extending the life of the reservoirs and bringing them into compliance
with current building and seismic codes. Padre Dam has 25 water storage reservoirs
with 56 MG of effective storage capacity, the majority of which is located in the Eastern
Service Area, with 33 MG of storage (59 percent of total). The remaining 23 MG (41
percent) of storage is located in the Western Service Area. Padre Dam’s storage
volume (30.7 MG, 55 percent) is stored in variable area concrete reservoirs that is part
of the “Five Reservoirs Retrofit Program.”
To date, Kleinfelder, Inc. has not provided any information about their work with Padre
Dam. They did share information on the cost of a recently completed study of 24
reservoirs (half steel tanks and half concrete tanks) for the City of San Bernardino of
about $10,000 per site.

Otay WD Facilities
The District is not underlain by known active or potentially active faults (i.e., faults that
exhibit evidence of ground displacement in the last 11,000 years and 2,000,000 years,
respectively). Major known active faults in the region consist generally of en-echelon,
northwest-striking, right-lateral, strike-slip faults. These include the Rose Canyon,
Coronado Bank, San Diego Trough, and San Clemente faults located to the west of the
District. The location of these faults are shown on Figure 1. Based on published
geological data, the Rose Canyon fault is the closest active fault to the District capable
of generating a maximum moment magnitude 6.9 earthquake. The La Nacion fault
zone is not plotted within the District boundary on this exhibit, but is not considered
active. It is located in the southwest portion of the District near the Rancho del Rey
community of the City of Chula Vista. No District facilities are located within a State of
California Alquist-Priolo Special Studies Zone for earthquake faults.
Similar to the City of San Diego, the highest risk for the District are breaks in the
pipelines that make up the District’s transmission and distribution system. The City of
San Diego report notes liquefaction as the highest pipeline risk hazard followed by
landslides and faults. On Figure 2, areas of liquefaction and landslide prone areas
within the District are identified. Any pipeline crossing one of these zones could be
affected during a seismic event. Unlike the City of San Diego, the District’s pump
stations already have onsite generators to respond where fire threat is high following an
earthquake.
All reservoirs and pump stations constructed after 1988 are assumed to be resistant to
earthquakes due to seismic requirements included in the 1988 Uniform Building Code
(1988 UBC). Table-1 identifies District reservoirs and the date of construction.
Approximately half (21 out of 40 total) of the District’s potable reservoirs were
constructed after that 1988 UBC update. The District’s newer reservoirs would be relied
on, following an earthquake, to continue to provide water to their pressure zone(s).
The District’s oldest reservoir was constructed in 1957, but will be retired after it reaches
the end of its useful life. This reservoir storage is not needed in the north district with
the construction of the Jamacha Road 36-Inch pipeline to FCF No. 14 and the
construction of the two 640 reservoirs in 2009. The 978-1 reservoir constructed in 1959
is the second oldest reservoir in the District and one of the smallest at 0.53 MG. The
978-2 reservoir was constructed in 1992 to provide an additional 2.5 MG of storage to
this pressure zone. The District typically has multiple reservoirs for each pressure zone
to provide more storage and add redundancy if one reservoir is taken out of service for
maintenance or is damaged. Every time the District rehabilitates a reservoir, the
components replaced are designed to meet the latest seismic requirements.
Staff also contacted NV5 about their experience on reservoir retrofit recommendations.
They noted that they have provided services for six reservoirs with some being roof
rafter replacement with new center halo support and others more extensive adding
6
thickening bottom plates and foundation anchors. They noted the costs for the retrofit
can approach the cost of replacement of the reservoir.
Table-2 identifies District pump stations and the date of construction. Approximately
60% (13 out of 21 total) of the District’s pump stations were constructed after that 1988
UBC update. Many of these can pump to a closed pressure system, if a reservoir is out
of service. Multiple pump stations serve the 980 pressure zone, one of the District’s
largest service areas. Two trailer mounted portable pumps are also available to be put
into service in critical areas of the District on an emergency basis.
Table-3 identifies District sewer lift stations. Only one sewer pump station, of the five
total, was constructed after the 1988 UBC update. Also, the RWCWRF treatment plant
was built prior to the 1988 UBC update. All new and replacement District facilities are
built to meet California seismic code requirements.
The District has planned for and built in redundancy in its infrastructure that should help
the District to continue to operate during an extreme event. The District will continue to
monitor studies prepared by the Water Authority and other agencies on their emergency
preparations.

STAFF REPORT
TYPE MEETING: Regular Board
MEETING DATE: January 3, 2018
SUBMITTED BY:
Dan Martin
Engineering Manager
PROJECT: VARIOUS DIV. NO. ALL
APPROVED BY:
Rod Posada, Chief, Engineering
Mark Watton, General Manager
SUBJECT: Informational Item – First Quarter Fiscal Year 2018 Capital
Improvement Program Report
GENERAL MANAGER’S RECOMMENDATION:
No recommendation. This is an informational item only.
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To update the Board about the status of all CIP project expenditures
and to highlight significant issues, progress, and milestones on
major projects.
ANALYSIS:
To keep up with growth and to meet our ratepayers' expectations to
adequately deliver safe, reliable, cost-effective, and quality water,
each year the District staff prepares a Six-Year CIP Plan that
identifies the District’s infrastructure needs. The CIP is comprised
of four categories consisting of backbone capital facilities,
replacement/renewal projects, capital purchases, and developer's
reimbursement projects.
2
The First Quarter Fiscal Year 2018 update is intended to provide a
detailed analysis of progress in completing these projects within the
allotted time and budget of $20.1 million. Expenditures through the
First Quarter totaled approximately $1.9 million. Approximately 9%
of the Fiscal Year 2018 expenditure budget was spent (see Attachment
B).
As part of the Fourth Quarter Fiscal Year 2017 Capital Improvement
Program Report, staff was directed to explore the feasibility of
providing a fiscal year graph showing a connection between total CIP
project completion status vs. total CIP expenditures. In reviewing
the feasibility of the requested graph, staff has noted that there
are specific challenges with how to represent the different project
phases for multi-year projects within a fiscal year and present them
in a meaningful way that would add value to the Board’s decision-
making process. Staff notes that visibility and transparency
regarding an individual project’s progress is communicated within the
comments provided in the Expenditure Report (see Attachment B) that
is part of this staff report. Progress and CIP project completion is
also provided on a project by project basis in the General Manager’s
report.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer
No fiscal impact as this is an informational item only.
STRATEGIC GOAL:
The Capital Improvement Program supports the District’s Mission
statement, “To provide high value water and wastewater services to
the customers of the Otay Water District in a professional,
effective, and efficient manner” and the District’s Vision, “A
District that is at the forefront in innovations to provide water
services at affordable rates, with a reputation for outstanding
customer service.”
LEGAL IMPACT:
None.
