APPROVED BY: Pedro Porras, Chief of Water Operations
German Alvarez, Assistant General Manager
Mark Watton, General Manager
SUBJECT: AUTHORIZE AGREEMENT WITH KIRK PAVING FOR ANNUAL AS-NEEDED
PAVING SERVICES
GENERAL MANAGER’S RECOMMENDATION: That the Board authorize entering into an agreement with Kirk Paving in an amount not to exceed $175,000 for as-needed asphalt paving services from July 1, 2014 through June 30, 2015.
COMMITTEE ACTION:
Please see attachment A.
PURPOSE:
To present bid results and request that the Board authorize entering into an agreement with Kirk Paving, Lakeside, CA for as-needed asphalt paving services from July 1, 2014 through June
30, 2015 in an amount not to exceed $175,000.
ANALYSIS: As a regular course of business, the District is required to
maintain and repair its water delivery infrastructure. Routinely this work requires the removal and re-installation of asphalt
paving in public roadways. It has been shown more effective and efficient for the District to use outside contractors for its
asphalt paving work. Therefore, the District has used outside asphalt paving contract services for more than nine (9) years.
As-needed paving services have been included in the FY 2015 Operating Budget under Contracted Services. The FY 2015 budget for annual as-needed paving under Contracted Services is $175,000.
In accordance with District’s purchasing requirements, a notice was published and bids were solicited for this work on a “unit price” basis. On March 20, 2014 eleven (11) contractors attended a mandatory pre-bid meeting and on April 7, 2014 bids were
received and publicly opened with the following results from seven (7) bidders:
Bidder Weighted
Score
Kirk Paving 501.04
Miller Paving 549.84
Frank & Son 579.5
Angus Asphalt 658.6
Hardy & Harper Paving 685.3
Alcantara Paving 776.3
SRM 754
The bidder with the lowest weighted score is determined to be the lowest responsible bidder, in this case it is Kirk Paving,
Lakeside CA. Attachment B was produced by the purchasing manager and is attached. Kirk Paving served as the FY 2014 as-needed paving service contractor for the District and has performed all required work
with no issues noted. Staff is confident that they will continue to be able to perform the required work. Bids have been submitted on a unit-cost basis for the different types of work typically required during paving. The types of
work are assigned a weight factor based on the District’s experience of the frequency they will be employed during the
term of the agreement and these weights are multiplied by the unit cost to determine a unit score. Unit scores are totaled to provide the overall score of the bid and the contractor with the
lowest overall score is the low bidder. Please refer to Attachment B.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer
The FY 2015 budget request includes $175,000 for as-needed paving services. The project manager has projected that this
requested amount is sufficient to meet the paving needs in the 2015 fiscal year.
STRATEGIC GOAL:
Strategy: Stewards of Public Infrastructure Goal: Conduct the best practice preventative maintenance
activities.
LEGAL IMPACT: None.

SUBJECT: Award of a Professional Engineering Design Services Contract
to Rick Engineering Company for the Campo Road Sewer Main
Replacement Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board)
award a professional Engineering Design Services contract to Rick
Engineering Company (Rick Engineering) and authorize the General
Manager to execute an agreement with Rick Engineering for design and
construction support of the Campo Road Sewer Main Replacement
Project in an amount not-to-exceed $805,705 (see Exhibit A for
Project location).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board authorization for the General Manager to enter into
a professional Engineering Design Services contract with Rick
Engineering for design and construction support of the Campo Road
Sewer Main Replacement Project in an amount not-to-exceed $805,705.
2
ANALYSIS:
The District requires the services of a professional engineering
design consultant in support of the Campo Road Sewer Main
Replacement Project (Project). The Project was originally identified
in the Wastewater Management Plan as being deficient in several
segments of its length, creating the potential for a sewage spill.
Much of the alignment is located in an environmentally sensitive
area where maintenance is greatly hindered and access to make a
repair requires environmental permitting. A sewage spill in this
area would have a significant impact and potentially not be noticed
immediately.
The Project includes the replacement of approximately 9,225 linear
feet of 10-inch gravity sewer with a new 15-inch gravity sewer
system, starting at the Avocado Boulevard entrance to the Rancho San
Diego Village Shopping Center, along SR-94/Campo Road to Singer
Lane. Additionally, the Project includes the repair/replacement of
four segments of 8-inch gravity sewer located along Avocado
Boulevard, Campo Road at Via Mercado, and the Rancho San Diego
Village Shopping Center to rectify existing deficiencies due to
piping sags, root intrusion, and/or pipe damage. Refer to Exhibit A
for a map view of the locations described above.
The District requires a consulting team to provide a range of
professional services, including civil, pipeline, Caltrans
permitting, environmental, surveying, geotechnical, potholing,
public outreach, and constructability reviews associated with the
Project. With the existing and replacement sewer alignment running
along Route 94/Campo Road, a knowledge of Caltrans requirements is
seen as a vital part of the Project.
The District solicited engineering design services by placing an
advertisement on the Otay Water District’s website on January 24,
2014 and with various other publications including the San Diego
Daily Transcript. Fourteen (14) firms submitted a letter of
interest and a statement of qualifications. The Request for
Proposal (RFP) for Engineering Design Services was sent to fourteen
(14) of the firms resulting in five (5) proposals received on
February 26, 2014.

RBF Consulting

Among the engineering design firms that submitted letters of
interest, but did not propose were: Aegis, Atkins, Dudek, ICF, J.C.
Heden and Associates, KEH, Kennedy-Jenks, Landmark, and Nasland.
In accordance with the District’s Policy 21, Staff evaluated and
scored all written proposals and interviewed the five (5) firms on
March 26, 2014. Rick Engineering received the highest score for
their services based on their extensive and direct experience in the
Project area, comprehensive understanding of the scope of work,
proposed method to accomplish the work, and they provided the best
overall value to the District. A summary of the complete evaluation
is shown in Exhibit B.
Rick Engineering stood out among the submitting firms because their
lead Caltrans Coordinator was involved on the Campo Road/Jamacha
Road widening project which is the same area as this Project. The
firm was also integrally involved in the development of the Skyline
Wesleyan Church, Rancho San Diego Sheriff Substation, and Rancho San
Diego Town Center, all located along the proposed sewer alignment.
Their knowledge of the existing conditions in the area is seen as an
asset to the Project.
Fee negotiation with Rick Engineering concluded on March 28, 2014,
which resulted in a fee decrease of $179,995 from their original
proposal fee of $985,700, yielding the revised proposed fee of
$805,705. The scope of services was not changed by the fee
negotiation. Staff reviewed the revised fee and concluded that the
modifications were appropriate.
Rick Engineering submitted the Company Background Questionnaire as
required by the RFP and staff did not find any significant 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.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer
The total budget for CIP S2024, as approved in the FY 2014 budget,
is $5,500,000. Total expenditures, plus outstanding commitments and
forecast, are $910,522. See Attachment B Budget Detail.
Based on a review of the financial budget, the Project Manager
anticipates that the budget for CIP S2024 will be sufficient to
support the Project.
The Finance Department has determined that 100% of the funding is
available through the Betterment Fund.

an updated 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
California Environmental Quality Act (CEQA) environmental
documentation. The original WSA&V report for the Resort Project
2
was approved by the District in February 2009. An updated WSA&V
report is needed because of changes in the configuration of the
Project and in the Project’s potable water demand. There have
also been updates to the planning documents that include the
Resort Project since the original approval by the Board.
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 January 2014 WSA&V Report for this Project.
The WSA&V Report was prepared by the District in consultation
with Dexter Wilson Engineering, 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, and
the Resort Project WSA&V Report is provided as Exhibit D.
The County is the responsible land use agency for the Resort
Project that requested an updated SB 610 and SB 221 water supply
assessment and verification report from the District. The
request for the updated 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.
3
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.
The Resort Project is located in the unincorporated area of San
Diego County. The Upper and Lower Otay Reservoirs generally
bound the Project to the west and south. The Resort Project is
not currently within the jurisdictions of the District, Water
Authority, and Metropolitan Water District of Southern
California (MWD), but will be annexed into these jurisdictions
at a later date.
The Resort Project is approximately 1,869 acres and is planned
as a combination of land uses consisting of a resort/hotel and
associated facilities, a mix of single-family residential
neighborhoods, a multiple use neighborhood, an elementary
school, a public safety facilities site, commercial, open space,
preserve land, circulation elements, parks, and recreational
facilities. The total number of resort/hotel units is planned
to be 200. Approximately 527 acres of the total Project site
are designated for 1,881 single-family detached homes and 57
multi-family homes are part of a multiple use site with up to
20,000 square feet of commercial/retail uses. Typically, a
development project of this magnitude is constructed in several
phases over many years. The table below provides a comparison
between the land uses proposed in the January 2009 WSA&V report
and the current WSA&V report (January 2014).

The expected potable water demand for the Resort Project is 1.44
million gallons per day (MGD) or about 1,615 acre-feet per year
4
(AFY). This is 142 AFY lower than the demand estimate in the
January 2009 WSA&V report that was prepared for the Project and
approved by the Board in February 2009. The previously
estimated 1,757 AFY demand (January 2009 WSA&V) was accounted
for in the District’s 2010 Urban Water Management Plan (UWMP)
and the Water Authority’s 2010 UWMP. Therefore, based on the
findings from the District’s 2010 UWMP and the Water Authority’s
2010 UWMP, this Project will result in no unanticipated demands.
The January 2009 WSA&V Report for the Resort Project considered
that recycled water could be used for landscape irrigation, off-
setting 417 AFY of potable water, although the project had not
yet received regulatory approval for the use of recycled water.
The entire watershed of the Resort 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 developers of the Resort
Project (JPB Development, LLC and Baldwin and Sons, LLC) have
met with and discussed the use of recycled water with the City
of San Diego, the owner and operator of the reservoirs. The
City of San Diego will not allow the Project to use recycled
water because they are concerned about the runoff from the
Project entering the reservoirs and increasing nutrients and
salinity (see Exhibit C for letters regarding recycled water use
from the developers and the City of San Diego). For this
reason, the projected water use within the Resort Project has
been estimated with the assumption that the use of recycled
water within the Project will not be allowed.
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 subdivision of more than
500 dwelling units.
Pursuant to SB 610 and SB 221, the updated 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 MWD. The District
prepared the updated WSA&V Report in consultation with Dexter
Wilson Engineering, 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 and in single-
and multiple-dry years to meet the projected demand of the
5
Resort 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 Otay Ranch Resort Village Project
updated WSA&V Report. The reimbursement was accomplished via an
$8,000 deposit the Project proponents placed with the District
on January 7, 2014.
STRATEGIC GOAL:
The preparation and approval of the updated WSA&V Report for the
Otay Ranch Resort Village 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 Strategic Goal, in planning for infrastructure and
supply to meet current and future potable water demands.
LEGAL IMPACT:
Approval of an updated WSA&V Report for the Otay Ranch Resort
Village Project in form and content satisfactory to the Board of
Directors would allow the District to comply with the
requirements of Senate Bills 610 and 221.

Background Information
The Otay Water District (District) prepared the January 2014 updated Water Supply
Assessment and Verification (WSA&V) Report for the Otay Ranch Resort Village Project at the request of the County of San Diego. The County’s WSA&V request letter
was received by the District on February 10, 2014 so the 90-day deadline for the District
to provide the Board an approved WSA&V Report to the City ends May 8, 2014. The
Resort Village Project is located within the 23,000 acre Otay Ranch master planned
community within the unincorporated area of the County of San Diego. See Exhibit A for the Project location.
The Otay Ranch Resort Village Project is not currently within the jurisdictions of the
District, the San Diego County Water Authority (Water Authority), and the Metropolitan Water District of Southern California (MWD), but will be required to annex into these jurisdictions in order to obtain permanent imported water supply service.
The January 2014 updated WSA&V Report for the Otay Ranch Resort Village Project
has been prepared by the District in consultation with Dexter Wilson Engineering, 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 January 2014
updated WSA&V Report for the Otay Ranch Resort Village Project.
The Otay Ranch Resort project, also referred to as the Resort or Village 13, is included within a land use planning document known as, “The Otay Ranch General Development Plan/Sub-Regional Plan” (Otay Ranch GDP). The County of San Diego and City of
Chula Vista jointly prepared and adopted the Otay Ranch GDP. The Resort project,
identified as Village 13 in the Otay Ranch GDP, is located within what is defined as the
Proctor Valley Parcel of the Otay Ranch GDP. The project is a part of the designated 14 villages and five (5) planning areas within the Otay Ranch GDP area. The Resort project current development plan approval is dependent on the County’s eventual
adoption of their entitlement application.
The Chula Vista City Council and the San Diego County Board of Supervisors adopted the Otay Ranch GDP on October 28, 1993, which was accompanied by a Program
Environmental Impact Report EIR-90-01 (SCH #89010154).
The approximately 23,000 acre Otay Ranch is a master-planned community that includes a broad range of residential, commercial, retail, and industrial development interwoven with civic and community uses, such as libraries, parks, and schools,
together with an open space preserve system consisting of approximately 11,375 acres.
The proposed development concept for the approximately 1,869 acres is generally planned as a combination of land uses consisting of a resort/hotel and associated facilities, a mix of single-family residential neighborhoods, a multiple use neighborhood,
an elementary school, a public safety facilities site, commercial, open space, preserve
land, circulation elements, parks, and recreational facilities. The total number of
resort/hotel units is planned to be 200. Approximately 527 acres of the total project site
are designated for 1,881 single-family detached homes and 57 multi-family homes are part of a multiple use site with up to 20,000 square feet of commercial/retail uses.
Typically, a development project of this magnitude is constructed in several phases over
many years.
The expected potable water demand for the Otay Ranch Resort Village Project is 1.44
million gallons per day (MGD) or about 1,615 acre-feet per year (AFY). This is 142 AFY lower than the demand estimate in the January 2009 WSA&V that was prepared for the
project and approved by the Board in February 2009. Therefore, based on the findings
from the Otay WD’s 2010 UWMP and the Water Authority’s 2010 UWMP, this Project
will result in no unanticipated demands.
The entire watershed of the Resort 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 developers of the Resort Village Project (JPB Development, LLC and Baldwin and Sons, LLC) 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
that the project 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 Resort project has been estimated with the assumption that the use of recycled water within the project will not be allowed.
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 2010 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
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 October 2010 approved the update of their Integrated Water Resources Plan
(IRP). The 2010 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 Federal Court ruling on previous operational limits on Sacramento-San
Joaquin Delta to protect the Delta species. Water agencies are still trying to
determine what effect the ruling will have on State Water Project (SWP)
deliveries. Actual supply curtailments for MWD are contingent upon fish distribution, behavioral patterns, weather, Delta flow conditions, and how water
supply reductions are divided between state and federal projects.
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 (December 11, 2012), the Water Authority’s current preferential
right is 17.22% of MWD’s supply, while the Water Authority accounted for approximately
25% 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.
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 Otay Ranch Resort Village 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 2010 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 Otay Ranch Resort Village Project WSA&V Report does
not in any way guarantee water supply to the parcels that make up the Otay Ranch Resort Village 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.
So the best the District can do right now is to state 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 Otay Ranch Resort Village Project updated WSA&V
Report, the Otay Ranch Resort Village Project proponents can proceed with the draft environmental documentation required for the CEQA review process. The water supply
issues will be addressed in these environmental documents, consistent with the
updated 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 Otay Ranch Resort
Village Project.
Some recent actions regarding water supply assessments and verification reports by Otay Water District are as follows:
The Board approved water supply assessment and verification reports for the
City of Chula Vista Village 8 West Sectional Plan Area and Village 9 Sectional
Plan Area on January 5, 2011.
The Board approved the water supply assessment report for the San Diego-
Tijuana Cross Border Facility on February 2, 2011.
The Board approved the water supply assessment for the County of San Diego
Rabago Technology Park on April 6, 2011.
The Board approved the water supply assessment report for the Pio Pico Energy
Center Project on October 5, 2011.
The Board approved the water supply assessment report for the Hawano Project on March 7, 2012.
The Board approved the water supply assessment reports for the Sunroad Otay
Plaza and Otay Tech Center Projects on March 6, 2013.
The Board approved the water supply assessment reports for the Otay Ranch
Planning Area 12 Freeway Commercial Project and the City of San Diego Otay
Mesa Community Plan Update on July 3, 2013.
The Board approved the water supply assessment report for the University
Villages project on November 6, 2013.
Water supplies necessary to serve the demands of the proposed Otay Ranch Resort
Village 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 updated 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 Otay Ranch Resort
Village 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 Otay Ranch Resort Village Project and the existing and other
planned development projects within the District.
Accordingly, after approval of an updated WSA&V Report for the Otay Ranch Resort
Village 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: 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 Otay Ranch Resort Village 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 Otay Ranch Resort Village 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 Otay Ranch Resort Village
Project.
Senate Bill (SB) 221 Water Supply Verification: The District's Board of Directors
approved WSA&V Report may be incorporated into the County’s Otay Ranch Resort
Village 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 Resort Village Project, may cite the approved WSA&V Report as
verification of intended sufficient water supply to serve the Project.

RE: Removal of Recycled Water in Otay Ranch Resort Village Project, TM 5361 (A) and (B)
Dear Mr. Kennedy:
Otay Water District approved a Water Supply and Assessment Verification Report for the Resort Village
project in January 2009 which contemplated the potable water demand for the Resort Village project.
The approved WSAV noted the potable demand could be reduced through the use of recycled water;
however, due to the proximity of the project site to the Lower Otay Reservoir, a water supply source
owned and controlled by the City of San Diego, as well as historic constraints by the RWQCB, the use of
recycled water was not a condition of approval of the WSAV, rather, OWD required the applicants to
pursue the use of recycled water.
Subsequent to the approval of the prior WSAV, the applicants worked with the City of San Diego to
design a water quality treatment system acceptable to the City to protect the water quality of Lower
Otay Reservoir. This letter is to provide additional detail to the Otay Water District on the City of San
Diego’s review of the Resort Village Project related to the use of recycled water and to clarify why
recycled water service was removed from the Project. On July 13, 2011, the City completed a
preliminary review of the Project’s Drainage Study and Storm Water Management Plan.
In their attached review letter, the City of San Diego identified salt loading as a “major concern for
surface water reservoirs in the San Diego Region” (please see comment #10 from the City’s Public
Utilities Department). The City stated in comment #12 that “the City is very concerned about salt
loading from the Project area into Otay Reservoir. This problem is exacerbated by the proposed use of
recycled water to irrigate landscaping in the project area. Recycled water carries salt loads well in
excess of the drinking water standard. Salt in recycled water is about double that in imported water and
about four times that in local runoff.” The City of San Diego has taken a similar position on other
projects tributary to the reservoir including Rolling Hills Ranch Phase 2 and portions of the EastLake
Master Plan Community.

Water Supply Assessment and Verification Report
January 2014
Otay Ranch Resort Village
Executive Summary
The Otay Water District (Otay WD) prepared this updated Water Supply Assessment and
Verification Report (WSA&V Report) at the request of the County of San Diego (County) for
the Otay Ranch Resort Village project, hereafter referred to as the Resort project. JPB
Development, LLC and Baldwin and Sons, LLC submitted an entitlement application to the
County for the development of the Resort project.
Project Overview and Water Use
The Resort project is not currently located within the jurisdictions of the Otay WD, the San
Diego County Water Authority (Water Authority), and the Metropolitan Water District
(MWD). The Resort project is required to annex into the jurisdictions of the Otay WD, Water
Authority, and MWD to utilize imported water supply (i.e. to obtain imported water supply
service).
The Resort project is identified and described within a land use planning document known as
the Otay Ranch General Development Plan/Sub-regional Plan (Otay Ranch SRP). The
County of San Diego and City of Chula Vista jointly prepared and adopted the Otay Ranch
SRP. The Resort project, identified as Village 13 within the Otay Ranch SRP, is located
within what is defined as the Proctor Valley Parcel of the Otay Ranch SRP. The Resort
project is part of the designated 14 villages and five planning areas within the Otay Ranch
SRP area. The Chula Vista City Council and the San Diego County Board of Supervisors
adopted the Otay Ranch SRP on October 28, 1993, which was accompanied by a Program
Environmental Impact Report EIR-90-01 (SCH #89010154). As the Otay Ranch area has
developed over time, the Otay Ranch SRP has been periodically amended to address land use
and circulation element issues specific to individual Villages.
The JPB Development, LLC and Baldwin and Sons, LLC (“Applicants”) proposed
development concept for the approximately 1,869 acre Resort property is generally planned as
a combination of land uses. These land uses consist of a resort/hotel and associated facilities,
a mix of single family residential neighborhoods, a multiple use neighborhood, an elementary
school, a public safety facilities site, commercial, open space, preserve land, circulation
elements, parks, and recreational facilities. The total number of resort/hotel units is planned
to be 200. Approximately 527 acres of the total project site are designated for 1,881 single-

family detached homes and 57 multi-family homes are part of a multiple use site with up to
20,000 square feet of commercial/retail uses. Typically a development of this magnitude is
constructed in several phases over many years.
The expected potable water demand for the Resort Project is 1.44 million gallons per day
(mgd) or about 1,615 acre feet per year (AFY). This is 142 AFY lower than the demand
estimate in the January 2009 WSA&V Report that was prepared for the project and approved
by the Otay WD Board (February 2009). The previously estimated 1,757 AFY demand
(January 2009 WSA&V Report) was accounted for in the District’s 2010 Urban Water
Management Plan (UWMP) and the Water Authority’s 2010 UWMP. Therefore, based on the
findings from the Otay WD’s 2010 UWMP and the Water Authority’s 2010 UWMP, this
project will result in no unanticipated demands.
The entire watershed of the Resort 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 the Resort Village Project, JPB Development, LLC and Baldwin and Sons, LLC, 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 that the project 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 Resort
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 Metropolitan Water District (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 may require water supply assessment and/or
verification reports for proposed land developments that are not within the Otay WD, Water
Authority, nor MWD jurisdictions (i.e. pending or proposed annexations) or that have revised
land use plans than what is reflected in the existing growth forecasts. The Otay WD, Water
Authority, and MWD next demand forecast and supply requirements and associated planning
documents will capture any increase or decrease in demands and required supplies as a result
of annexations or revised land use planning decisions such as the proposed annexation of the
Resort project into Otay WD, Water Authority, and MWD jurisdictions. This WSA&V report
documents a decrease in the potable water demand of the Resort project since the previous
Otay Water District
Water Supply Assessment and Verification Report

WSA&V report (January 2009 WSA&V). This updated information will be incorporated
within and become a permanent part of the water resources planning processes and documents
for the Otay WD, Water Authority, and MWD.
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 conducting adequate planning 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 Integrated Resource Plan (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 2010
update to the IRP (2010 IRP Update) includes a planning buffer supply intended to mitigate
against the risks associated with implementation of local and imported supply programs. The
planning buffer identifies an additional increment of water that could potentially be developed
if other supplies are not implemented as planned. As part of implementation of the planning
buffer, MWD periodically evaluates supply development to ensure that the region is not under
or over developing supplies. Managed properly, the planning buffer will help ensure that the
southern California region, including San Diego County, will have adequate water supplies to
meet future demands.
Water supply agencies throughout California continue to face climatological, environmental,
legal, and other challenges that impact water source supply conditions, such as the court
rulings regarding the Sacramento-San Joaquin Delta issues and the current drought impacting
the western states. Challenges such as these will always be present. However, even in the
face of these challenges, the regional water supply agencies, the Water Authority and MWD,
along with Otay WD fully intend to have sufficient, reliable supplies to serve demands.
In Section ES-5 of MWD’s 2010 Regional Urban Water Management Plan (2010 RUWMP),
MWD states that MWD has supply capacities that would be sufficient to meet expected
demands from 2015 through 2035. 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. MWD’s 2010 RUWMP
identifies potential reserve supplies in the supply capability analysis (Tables 2-9, 2-10, and 2-
11), which could also be available to meet 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 the 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 2010 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 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.
Otay Water District Water Supply Development Program
In evaluating the availability of sufficient water supply, the Resort 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, detailed in the Otay WD’s 2010 UWMP, 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 alternative water supply projects are not currently developed
and are in various stages of the planning process. A few examples of these projects include
the Middle Sweetwater River Basin Groundwater Well project, the North District Recycled
Water Supply Concept, the Rosarito Ocean Desalination Facility project, and the Rancho del
Rey Groundwater Well project. The Water Authority and MWD’s next forecast 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 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 updated
Resort project WSA&V Report and will be included in the future water supply planning
documents of the Water Authority and MWD. The potable water demand projections and

supply requirements for the proposed Resort project are currently within the UWMP, WRMP,
and other water resource planning documents of the Otay WD.
To fully quantify probable demands to be served by the Water Authority, lands with
impending or proposed applications for annexation to the Otay WD, Water Authority, and
MWD service areas were identified in the Water Authority 2010 UWMP. Estimated water
demands for the Resort project were provided to the Water Authority and then added to the
Water Authority forecast. The Water Authority included the Resort project potable water
demands within their 2010 UWMP to provide for more comprehensive supply planning and
assist in complying with the requirements of Senate Bills 610 and 221.
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 Resort 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 project and the
existing and other planned development projects to be served by the Otay WD.
Accordingly, after approval of the updated WSA&V Report for the Resort 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 Resort 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 Resort project
EIR 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 Resort 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
Resort 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 Resort project’s Tentative Map, may cite the approved WSA&V Report as
verification of intended sufficient water supply to serve the Resort project.
Section 1 - Purpose

application package to the County of San Diego (County) for the development of the Resort
project. The County requested that Otay WD prepare a WSA&V Report for the Resort
project. This original WSA&V Report was approved by the Otay WD Board of Directors in
February, 2009. The County requested that an updated WSA&V Report be submitted for
approval because of changes in the configuration of the project and slight changes in the
potable water demand. Since 2009, there have also been updates to the planning documents
that include the Resort project. The current Resort project description is provided in Section 3
of this WSA&V Report.
This updated WSA&V Report for the Resort 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. The intent of these bills is 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 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 Resort project, and reasonably foreseeable
planned future water demands served by Otay WD. The Otay WD Board of Directors
approved WSA&V Report is planned to be used by the County in its evaluation of the Resort
project under the CEQA and Tentative Map approval processes.
Section 2 - Findings
The Otay WD prepared this updated WSA&V Report at the request of the County for the
Resort project. The Resort project is also known as Otay Ranch Village 13. JPB
Development, LLC and Baldwin and Sons, LLC submitted an entitlement application to the
County for the Resort project.

The Resort project is not currently within the jurisdictions of the Otay WD, Water Authority,
or MWD. The Resort project is required to annex into the jurisdictions of the Otay WD,
Water Authority, and MWD to utilize imported water supply (i.e. to obtain imported water
supply service).
The expected potable water demand for the Resort Project is 1,441,760 gallons per day (GPD)
or about 1,615 acre feet per year (AFY). The current development plan is expected to
decrease the water demand for this project by 142 AFY from the January 2009 Water Supply
Assessment and Verification Report that was prepared for the Resort project and approved by
the Otay WD Board.
The previously estimated 1,757 AFY (January 2009 WSA&V) demand was accounted for in
the Water Authority’s 2010 UWMP and the Otay WD’s 2010 UWMP. Therefore, the
updated expected potable water demand for the Resort Project of 1,615 AFY will not result in
any unanticipated demands since this amount is 142 AFY less than what was previously
anticipated for the Resort project.
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
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, nor MWD jurisdictions (i.e. pending or proposed annexations) or
that have revised land use plans 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 such as the proposed annexation
of the Resort project. The Resort project will be annexed into the jurisdictions of the Otay
WD, Water Authority, and MWD. In anticipation of this annexation, water demand and
supply planning information for the Resort project were incorporated into and became a
permanent part of their water resources planning processes and documents. Since the Resort
project had a WSA&V report approved by the Otay WD Board of Directors in 2009, the
Water Authority included the Resort project potable water demands within their 2010 UWMP
to provide for more comprehensive supply planning and assist in complying with the
requirements of Senate Bills 610 and 221.

This process is utilized by the Water Authority and MWD to document the water supplies
necessary to serve the demands of the proposed Resort project, along with existing and other
projected future users, as well as the actions necessary to develop these supplies. Through
this process, it is assured that the necessary demand and supply information is identified and
incorporated within the water supply planning documents of the Water Authority and MWD.
The Otay Water District 2010 UWMP included 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
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 has 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 Draft 20x2020 Water Conservation Plan. The Otay WD 2015 target
is 171 gpcd and the 2020 gpcd target at 80 percent of baseline is 152 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 economic
conditions. However, Otay WD’s effective water use awareness campaign and the enhanced
conservation mentality of its customers will likely result in some long-term carryover of these
reduced consumption rates.
To fully quantify probable demands to be served by the Water Authority, lands with
impending or proposed applications for annexation to the Otay WD, Water Authority, and
MWD service areas were identified in the Water Authority 2010 UWMP. Estimated water
demands for the Resort project were provided to the Water Authority and then added to the
Water Authority forecast. The Water Authority included the Resort project potable water
demands within their 2010 UWMP to provide for more comprehensive supply planning and
assist in complying with the requirements of Senate Bills 610 and 221.
In evaluating the availability of sufficient water supply, the Resort 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 Water District
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 new 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 North District Recycled Water Supply Concept, the Rosarito
Ocean Desalination Facility 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 any new water resources developed by the Otay WD.
Water supplies necessary to serve the demands of the proposed Resort project, along with
existing and other reasonably foreseeable projected future users, as well as the actions
necessary to develop these supplies and their status, will be identified and included within the
water supply planning documents of the Water Authority and MWD. This WSA&V Report
demonstrates and verifies that, with development of the resources currently identified and
those that may be additionally acquired, there are sufficient water supplies being planned for
and developed over the next 20-year planning horizon to meet the projected demand of the
proposed Resort project and any existing and other reasonably foreseeable planned
development projects within the Otay WD.
This WSA&V Report includes, among other information, an identification of existing water
supply entitlements, water rights, water service contracts, proposed water supply projects, or
agreements relevant to the identified water supply needs for the proposed Resort 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 to verify and document that sufficient water supplies
are being planned for and are intended to be acquired to meet projected water demands of the
Resort project and the 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.
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 (44,883 acre-feet (ac-ft)
in 2015 to 56,614 ac-ft in 2035 per the Otay WD 2010 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 6.4 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 demonstrate and verify that sufficient water supplies are being
planned for and are intended to be acquired, as well as the actions necessary and status to
develop these supplies are and will be further documented, to serve the proposed Resort
project and the existing and other reasonably foreseeable planned 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 Resort project, also referred to as the Resort or Village 13, is located in the
unincorporated area of the County of San Diego, California. Refer to Appendix A for a
regional location map for the proposed project. The Upper and Lower Otay Reservoirs
generally bound the Resort project to the west and south. The Resort project is not currently
within the jurisdictions of the Otay WD, Water Authority, and MWD.
The Resort project is included within a land use planning document known as the Otay Ranch
General Development Plan/Sub-regional Plan (Otay Ranch SRP). The County of San Diego
and City of Chula Vista jointly prepared and adopted the Otay Ranch SRP. The Resort
project, identified as Village 13 in the Otay Ranch SRP, is located within what is defined as
the Proctor Valley Parcel of the Otay Ranch SRP. The project is a part of the designated 14
villages and five planning areas within the Otay Ranch SRP area. The Resort project current
development plan approval is dependent on the County’s eventual adoption of their
entitlement application.
The Chula Vista City Council and the San Diego County Board of Supervisors adopted the
Otay Ranch SRP on October 28, 1993, which was accompanied by a Program Environmental
Impact Report EIR-90-01 (SCH #89010154).
The approximately 23,000 acre Otay Ranch is a master-planned community that includes a
broad range of residential, commercial, retail, and industrial development interwoven with
civic and community uses, such as libraries, parks, and schools, together with an open space
preserve system consisting of approximately 11,375 acres.
The proposed development concept for the approximately 1,869 acre Resort project is planned
as a combination of land uses as shown in Table 1.

The proposed development concept for the approximately 1,869 acre Resort property is
generally planned as a combination of land uses consisting of a resort hotel and associated
facilities, a mix of single and multi-family residential neighborhoods, a multiple-use
neighborhood, an elementary school, a public safety facilities site, commercial, open space,
preserve land, circulation elements, parks, and recreational facilities. The total number of
resort/hotel units is planned to be 200. Approximately 527 acres of the total project site are
designated for 1,881 single-family detached homes and 57 multi-family homes are proposed
as part of a multiple use site with up to 20,000 square feet of commercial/retail uses.
Typically a development of this magnitude is constructed in several phases over many years.
The County has identified discretionary actions and/or permit approval requirements for the
Resort project. The projected potable water demands and resulting water supply requirements
associated with the Resort project have considered the discretionary actions and/or permit
approvals and are incorporated into and used in this WSA&V Report. The water demands for
the proposed Resort project are 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 relies on the Water Authority for 100 percent of its treated potable
water supply. 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
12
obtains the vast majority of its imported supply from MWD, but is in the process of
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
effective treatment capacity of 1.2 million gallons per day (mgd) or about 1,300 acre feet per
year (ac-ft/yr) to produce recycled water. On May 18, 2007 an additional source of recycled
water supply, at least 6 mgd or about 6,720 ac-ft/yr, 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 2010 Water Resources Master Plan Update and
the Otay WD 2010 Urban Water Management Plan (2010 UWMP) includes 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 2-1 contained
within the Otay WD 2010 WRMP Revision shows the jurisdictional boundary of the Otay
WD and the Area of Influence which includes the Resort project area. 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 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 2010 figure of approximately 198,616 to an estimated 284,997 by 2035. 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
13
Mesa Specific Plan Area, San Diego County Community Plans, and City of San Diego Otay
Mesa Community Plan, 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
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
12.17 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.
4.1 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 2011 and
subsequently submitted the plan to the California Department of Water Resources (DWR).
As required by law, the Otay Water District 2010 UWMP includes projected water supplies
required to meet future demands through 2035. In accordance with Water Code Section
10910 (c)(2) and Government Code Section 66473.7 (c)(3), information from the Otay WD
2010 UWMP along with supplemental information from the 2010 Otay WD WRMP Revision
have been utilized to prepare this WSA&V 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
Otay Water District
Water Supply Assessment and Verification Report

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. The 2020 urban water use
target may be updated in a supplier’s 2015 UWMP.
In 2015, urban retail water suppliers will be 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 has 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 Draft 20x2020 Water Conservation Plan. The Otay WD 2015 target
is 171 gpcd and the 2020 gpcd target at 80 percent of baseline is 152 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 Otay Mesa Community
Plan, 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 is utilized in the preparation of the Otay WD 2010 WRMP Revision, and the
Otay WD 2010 UWMP in order 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
15
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
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 February 26, 2010, the
SANDAG Board of Directors accepted the Series 12: 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 also are used by local
governments for planning, including the San Diego County Water Authority 2010 Urban
Water Management Plan 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 2010 through 2035. These savings estimates were
then factored into the baseline municipal and industrial demand forecast.
A separate agricultural model, also used in prior modeling efforts, was used to forecast
agricultural water demands within the Water Authority service area. This model estimates
agricultural demand to be met by the Water Authority’s member agencies based on
agricultural acreage projections provided by SANDAG, crop distribution data derived from
the Department of Water Resources and the California Avocado Commission, and average
crop-type watering requirements based on California Irrigation Management Information
System data.
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 also 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 will 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
16
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 forecast
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 Resort 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 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. A few examples of these alternative water supply projects include the
Middle Sweetwater River Basin Groundwater Well project, the North District Recycled Water
Supply Concept, the Rosarito Ocean Desalination Facility project, and the Rancho del Rey
Groundwater Well project. The Water Authority and MWD’s next forecast and supply
planning documents would capture any increase in water supplies resulting from any new
water resources developed by the Otay WD.
In addition, MWD’s 2010 Regional UWMP identified potential reserve supplies in the supply
capability analysis (Tables 2-9, 2-10, and 2-11), which could be available to meet any
unanticipated demands. The Water Authority and MWD’s next forecast and supply planning
documents would capture any increase in necessary supply resources resulting from any new
water supply resources.
The Otay WD water demand projection methodology 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 acre-feet 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
17
for commercial and industrial land uses are estimated using 1,785 and 893 gallons per day per 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 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 2010 WRMP Revision 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). The potable net acreage is then multiplied by the unit demand factor corresponding to
its respective land use. This approach is used in the 2010 WRMP Revision 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.
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 2.

5.1 Demand Management (Water Conservation)
Demand management, or water conservation is a critical part of the Otay WD 2010 UWMP
and its long term strategy for meeting water supply needs of the Otay WD customers. Water
conservation, is frequently the lowest cost resource available to any water agency. The goals
of the Otay WD water conservation programs are to:
Reduce the demand for more expensive, imported water.
Demonstrate continued commitment to the Best Management Practices (BMP).
Ensure a reliable water supply.
The Otay WD is signatory 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.
Water conservation programs are developed and implemented on the premise that water
conservation increases the water supply by reducing the demand on available supply, which is
vital to the optimal utilization of a region’s water supply resources. The Otay WD
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
20
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 2 and 3 take into account implementation of water
conservation measures within Otay WD.
As one of the first signatories to the MOU Regarding Urban Water Conservation in
California, the Otay WD has made BMP implementation for water conservation the
cornerstone of its conservation programs and a key element in its water resource management
strategy. As a member of the Water Authority, Otay WD also benefits from regional
programs performed on behalf of its member agencies. The BMP programs implemented by
Otay WD and regional BMP programs implemented by the Water Authority that benefit all
their member agencies are addressed in the Otay WD 2010 UWMP. 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 conservation 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 Supervisor 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 these functions provide for operating personnel to monitor the water supply
source flow rates, reservoir levels, turn on or off pumping units, etc. The SCADA system
aids in the prevention of water reservoir overflow events and increases energy efficiency.
Water Conservation Ordinance
California Water Code Sections 375 et seq. permit public entities which supply water at
retail to adopt and enforce a water conservation program to reduce the quantity of water
used by the people therein for the purpose of conserving water supplies of such public
entity. 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.
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
21
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 finds and determines 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 and that the
conservation of such water be encouraged 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 is currently engaged in a number of conservation and water use efficiency activities.
Listed below are the current programs that are either on-going or were recently concluded:
Residential Water Surveys: 1,349 completed since 1994
Large Landscape Surveys: 194 completed since 1990
Cash for Water Smart Plants Landscape Retrofit Program: over 217,600 square feet of
turf grass replaced with water wise plants since 2003
Rotating Nozzles Rebated: 3,170
Residential Weather-Based Irrigation Controller (WBIC) Incentive Program: 231
distributed or rebated since 2004
Residential High Efficiency Clothes Washers: 7,187 rebates since 1994
Residential ULFT/HET Rebate Program: 22,376 rebates provided between 1991-2010
Outreach Efforts to Otay WD Customers - the Otay WD promotes its conservation
programs through staffing outreach 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 through the Water Authority’s marketing efforts.
School Education Programs- the Otay WD funds school tours of the Water
Conservation Garden, co-funds Splash Labs, provides classroom water themed kits,
maintains a library of school age appropriate water themed books, DVDs, and videos,
and runs both a school poster contest and a water themed photo contest.
Water efficiency in new construction through Cal Green and the Model Water
Efficient Landscape Ordinance
Focus on Commercial/Institutional/Industrial through Promoting MWD’s Save a Buck
(Commercial) Program in conjunction with the Otay WD’s own Commercial Process
Improvement Program
As a signatory to the MOU Regarding Urban Water Conservation in California, the Otay WD
is required to submit biannual reports that detail the implementation of current water
conservation practices. The Otay WD voluntarily agreed to implement the fourteen water
conservation Best Management Practices beginning in 1992. The Otay WD submits its report
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
22
to the CUWCC every two years. The Otay WD BMP Reports for 2005 to 2010, as well as the
BMP Coverage Report for 1999-2010, are included in the Otay WD 2010 UWMP.
The Resort project will implement the CUWCC Best Management Practices for water
conservation such as installation of ultra low flow toilets, development of a water
conservation plan, and potential beneficial use of recycled water, all of which are typical
requirements of development projects within the County of San Diego.
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. 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 through two delivery pipelines, referred to as Pipeline No. 4 and the 36-
inch Jamacha Pipeline, currently supply the Otay WD with 100 percent of its potable water.
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 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 2010 Regional
Urban Water Management Plan
In November 2010, MWD adopted its 2010 Regional Urban Water Management Plan
(RUWMP). The 2010 RUWMP 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
2010 RUWMP, MWD also utilized the current 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
23
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
2010 RUWMP documents the availability of these existing supplies and additional supplies
necessary to meet future demands.
6.1.1.1 MWD Supplies
MWD’s Integrated Resources Plan (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 2010
update to the IRP (2010 IRP Update) includes a planning buffer supply intended to mitigate
against the risks associated with implementation of local and imported supply programs. The
planning buffer identifies an additional increment of water that could potentially be developed
if other supplies are not implemented as planned. As part of implementation of the planning
buffer, MWD periodically evaluates supply development to ensure that the region is not under
or over-developing supplies. Managed properly, the planning buffer will help ensure that the
southern California region, including San Diego County, will have adequate supplies to meet
future demands.
In November 2010, MWD adopted its 2010 RUWMP in accordance with state law. The
resource targets included in the preceding 2010 IRP Update serve as the foundation for the
planning assumptions used in the 2010 RUWMP. MWD’s 2010 RUWMP contains a water
supply reliability assessment that includes a detailed evaluation of the supplies necessary to
meet demands over a 25-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 2010 RUWMP, that 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 2015.
The 2010 RUWMP 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 2010 RUWMP can be found
on the World Wide Web at the following site address: http://www.mwdh2o.com/mwdh2o/
pages/yourwater/RUWMP/RUWMP_2010.pdf
Water supply agencies throughout California continue to face 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 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
As part of MWD’s annual budget approval process, a Capital Investment Plan is prepared.
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 2010 UWMP in June 2011. The updated Water Authority 2010 UWMP
identifies a diverse mix of local and imported water supplies to meet future demands.
A copy of the updated Water Authority 2010 UWMP can be found on the internet at
http://www.sdcwa.org/2010-urban-water-management-plan
Deliveries of conserved agricultural water from the Imperial Irrigation District (IID) to
San Diego County have increased annually since 2003, with 70,000 ac-ft of deliveries
in Fiscal Year (FY) 2010. These quantities will increase annually to 200,000 ac-ft/yr
by 2021, and then remain fixed for the duration of the transfer agreement.
As part of the October 2003 Quantification Settlement Agreement (QSA), the Water
Authority was assigned MWD’s rights to 77,700 ac-ft/yr 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.

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.

The Water Authority currently obtains imported supplies from MWD, conserved water from
the AAC and CC lining projects, and an increasing amount of conserved agricultural water
from IID. 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. As calculated by MWD, the Water Authority’s preferential right as of December
11, 2012 is 17.22 percent of MWD’s supply, while the Water Authority accounted for
approximately 25 percent of MWD’s total revenue. 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 2010 RUWMP, MWD
states that MWD has supply capacities that would be sufficient to meet expected demands
from 2015 through 2035. 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 2010 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 and water saved from the AAC and CC
lining projects. The CC lining project is complete and the Water Authority has essentially

completed construction of the AAC lining project. Table 5 summarizes the Water Authority’s
supply sources with detailed information included in the sections to follow. Deliveries from
MWD are also included in Table 5, which is further discussed in Section 6.1 above. The
Water Authority’s member agencies provided the verifiable local supply targets for
groundwater, groundwater recovery, recycled water, and surface water, which are discussed in
more detail in Section 5 of the Water Authority’s 2010 UWMP.

Note 1: On November 29, 2012, the Water Authority approved a water purchase agreement with Poseidon for 48,000 AFY
with the right to purchase up to 56,000 AFY
Section 5 of the Water Authority’s 2010 UWMP also includes a discussion on the local
supply target for seawater desalination. Seawater desalination supplies represent a significant
future 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. When the project becomes operational in 2016, it will more than double the amount
of local supplies developed in the region since 1991. The desalination plant itself will be fully
financed, built, and operated by Poseidon. The Water Authority will purchase water from the
plant under a water purchase agreement. The new pipeline connecting the desalination plant
with the Water Authority’s Second Aqueduct will be owned and operated by the Water
Authority, but responsibility for design and construction will reside with Poseidon through a
separate Design-Build Agreement. The Water Authority will be 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
Otay Water District

27
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.
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,
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 Water Purchase Agreement (WPA).
The Water Authority’s existing and planned supplies from the IID transfer and canal lining
projects are considered “drought-proof” supplies and should be available at the yields shown
in Table 6 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 2010
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 2010 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 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 throughout the San Diego region.
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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
28
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 1998 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.
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,
in violation of California’s constitution. The QSA parties appealed this decision and are
continuing to seek validation of the contracts. The appeal is currently pending in the Third
District Court of Appeal. A stay of the trial court judgment has been issued during the appeal.
Implementation of the transfer provisions is proceeding during litigation.
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. In
2012, the Water Authority will receive 90,000 acre feet per year. 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
the IID 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
Otay Water District
Water Supply Assessment and Verification Report

29
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 will take delivery of the transfer water through
its Colorado River Aqueduct. In exchange, MWD will deliver to the Water Authority a like
quantity and quality of water. The Water Authority will pay MWD’s applicable wheeling rate
for each acre-foot of exchange water delivered. According to the water exchange agreement,
MWD will make delivery of the transfer water for 35 years, unless the Water Authority elects 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
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-foot. 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 transportation charge in 2010 was $314 per acre-foot.
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

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 ac-ft/yr 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.
Otay Water District
Water Supply Assessment and Verification Report

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
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 10, 2003, Exchange Agreement between the Water Authority and MWD also
provides for the delivery of the conserved water from the canal lining projects. The Water
Authority will pay MWD’s applicable wheeling rate for each acre-foot of exchange water
Otay Water District
Water Supply Assessment and Verification Report

33
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 will also be 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.
Written Contracts or Other Proof
The expected supply and costs associated with the lining projects are based primarily on the
following documents:

6.2.1.3 Carlsbad Seawater Desalination Project
Development of seawater desalination in San Diego County will assist 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 currently being 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 2010 UWMP. The Carlsbad Desalination Project has obtained

all required permits and environmental clearances and, when completed, will provide 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, was selected by Poseidon to be 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,
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 establishes the commercial and technical terms for implementation of the
desalination product pipeline improvements. These improvements consist of an approximate
10-mile long, 54-inch diameter conveyance pipeline connecting the Desalination Plant to the
Water Authority’s Second Aqueduct. The pipeline will generally be constructed within
improved streets in commercial and industrial areas in the cities of Carlsbad, Vista, and San
Marcos. The Water Authority will own the Project Water Pipeline Improvements upon
execution of the Design-Build Agreement, and upon completion and acceptance of
construction, the Water Authority will assume operational control of all pipeline
improvements.

Expected Supply
When completed, the Project will provide 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 8% of the total projected
regional supply and 30% of all locally generated water in San Diego County. When the
project becomes operational in 2016, it will more than double the amount of local supplies
developed in the region since 1991.
Transportation
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 establishes the commercial and technical terms for implementation of the
desalination product pipeline improvements. These improvements consist of an approximate
10-mile long, 54-inch diameter conveyance pipeline connecting the Desalination Plant to the
Water Authority’s Second Aqueduct. The pipeline will generally be constructed within
improved streets in commercial and industrial areas in the cities of Carlsbad, Vista, and San
Marcos. The Water Authority will own the Project Water Pipeline Improvements upon
execution of the Design-Build Agreement, and upon completion and acceptance of
construction, the Water Authority will assume operational control of all pipeline
improvements.
The Water Authority will be 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.
Cost/Financing
The plant and the offsite pipeline will be 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.
A preliminary September 2012 unit cost estimate was $2,300/AF. 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 2005 UWMP and the 2002 Regional Water Facilities Master Plan. These CIP
projects, which are most recently described in the Water Authority’s Adopted Multi-Year
Budget, include projects valued at $3.50 billion. These CIP projects are designed to meet
projected water supply and delivery needs of the member agencies through 2035. 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 Resort Village
41
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,
complete the projects required under the Quantification Settlement Agreement (QSA),
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 WD 2010 WRMP Revision and the 2010 UWMP contain comparisons of projected
supply and demands through the year 2035. 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 Otay WD expansion of the market areas for the use of recycled water within the
watersheds upstream of the Sweetwater Reservoir, Otay Mesa, and the Lower Otay Reservoir
will increase recycled water use and thus require less dependence on imported water for
irrigation purposes.
Otay Water District
Water Supply Assessment and Verification Report

The supply forecasts contained within this WSA&V 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 6. 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 ac-ft/yr. 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
essentially completing construction and commencement of operations 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. In calendar year
2012 the supply to Otay WD was 31,268 ac-ft of supply from the Water Authority. An
additional 4,155 ac-ft of recycled water from the City of San Diego and from the District’s
Ralph W. Chapman Water Reclamation Facility. The demand for potable water within the
Otay WD is expected to increase to about 77,177 ac-ft by 2035 as per the Otay WD 2010
UWMP.
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.
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
44
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
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 ac-ft/yr 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, New Water Supply 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 ac-ft 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 to 50% share the capital cost to expand its
capacity from 8 mgd to 16 mgd.
Otay Water District

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 and on the Otay Mesa. 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, and other development projects.
The Otay WD projects that annual average demands for recycled water will increase to 8,000
acre-feet per year by 2035. 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 the quest 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
46
proximity of the recycled water markets in the North District to the Otay WD’s 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’s 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. At this time, the
effluent limit of concern is total nitrogen. An examination as to how the treatment process
might be modified to enhance nitrogen removal and an action plan is being developed. 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 ac-ft/yr. This saved imported water
could then be used to offset new potable water demands.

The Otay WD has and continues to construct recycled water storage, pumping, transmission,
and distribution facilities to meet projected recycled water market demands. For nearly 20
years, millions of dollars of capital improvements have been constructed. The supply link
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 are complete 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 ac-ft per year of recycled water from the SBWRP at an initial price of
$350 per acre-foot. The Otay WD 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.
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
Otay Water District

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 WD 2010 UWMP, the 2010 WRMP Revision, and the Otay WD March 2007
Integrated Water Resources Plan (2007 IRP) 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 a few 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 evolved and have been resurrected 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’s water supply portfolio consistent the Otay WD
2007 IRP.
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.
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

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
outlined above. It is anticipated that the cost for the entire scope of work, will be on the order
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
50
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 used as a potable water supply resource, a sanitary seal
must be installed in accordance with the CDPH 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.
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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
51
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
groundwater well production facility to extract approximately 500 acre-feet per year. For
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
52
water planning purposes, production of groundwater from the Rancho del Rey well is
considered “additional planned” for local supplies. The Otay WD has contracted for design
services for the wellhead treatment facilities.
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 likely not be designed or
operated by the Otay WD as the lead agency, 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 obtain
approval from the CDPH 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 CDPH 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

53
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 to establish water supply
resource acquisition terms through development of a Principles of Understanding document.
6.3.2 Otay WD 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 WD 2010 WRMP Revision.
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 precede 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 2010 WRMP Revision. 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 Resort project is not 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 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
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
54
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 such as the proposed annexation of the Resort project into Otay WD, Water
Authority, and MWD jurisdictions. The Resort project will be annexed into the jurisdictions
of the Otay WD, Water Authority, and MWD. In anticipation of this annexation, water
demand and supply planning information for the Resort project were incorporated into and
became a permanent part of their water resources planning processes and documents.
MWD’s Integrated Resources Plan (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 2010
update to the IRP includes a planning buffer supply intended to mitigate against the risks
associated with implementation of local and imported supply programs and for the risk that
future demands could be higher than projected. The planning buffer identifies an additional
increment of water that could potentially be developed when needed and if other supplies are
not fully implemented as planned. As part of implementation of the planning buffer, MWD
periodically evaluates supply development, supply conditions, and projected demands to
ensure that the region is not under or over developing supplies. Managed properly, the
planning buffer will help ensure that the southern California region, including San Diego
County, will have adequate water supplies to meet long-term future demands.
In Section ES-5 of their 2010 RUWMP, MWD states that they have supply capacities that
would be sufficient to meet expected demands from 2015 through 2035. 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. MWD’s 2010 RUWMP identifies potential reserve supplies in the supply capability
analysis (Tables 2-9, 2-10, and 2-11), 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.”
Otay Water District
Water Supply Assessment and Verification Report
Otay Ranch Resort Village
55
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 2010 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 Resort 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 Resort 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 Resort
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 Project. This
WSA&V 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
Resort project and the existing and other planned development projects to be served by the
Otay WD.
Table 7 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
2012 was 35,423 acre feet. The demand for FY 2012 is 5,736 acre feet lower than the
demand in FY 2005 of 41,159 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 8 presents the forecasted balance of water demands and supplies for the Otay WD
service area under single dry year conditions. Table 8 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 2015. The multiple dry year conditions for periods ending
in 2023, 2028, and 2033 are provided in the Otay WD 2010 UWMP. The projected potable
demand and supply requirements shown in Tables 7 and 8 are from the Otay WD 2010
UWMP and include the Resort project. Hot, dry weather may generate urban water demands
that are about 6.4 percent greater than normal. This percentage was utilized to generate the

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.
In evaluating the availability of sufficient water supply, the Resort 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 Resort 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 Resort 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.
