TITLE: Set Public Hearing Date for the 2020 Urban Water Management Plan
and Water Shortage Contingency Plan
ABSTRACT:
California requires all urban water suppliers to prepare an Urban Water Management Plan
every five years. The required water plan is used to support long-term resource planning
and ensure adequate water supplies are available to meet existing and future water
demands. The State of California (State) has also required a new, additional plan known
as the Water Shortage Contingency Plan. This is another strategic planning document
designed to prepare for and respond to water shortages. In conjunction with regional
water agencies, the Utilities Department staff prepared these documents for public review
and proposes that they be adopted by the City Council on June 8, 2021.
RECOMMENDATION:
a) Determine this action is exempt from the California Environmental Quality Act (CEQA)
pursuant to Sections 15060(c)(2) and 15060(c)(3) of the CEQA Guidelines because
this action will not result in a physical change to the environment, directly or indirectly;
b) Receive the draft Urban Water Management Plan, the Water Supply Contingency
Plan, and the Addendum to the 2015 Urban Water Management Plan for review; and
c) Set the date of June 8, 2021 for a public hearing.
DISCUSSION:
What is an Urban Water Management Plan?
Every urban water supplier providing water for municipal purposes to more than 3,000
customers, or supplying more than 3,000 acre-feet (AF) of water annually, is required to
prepare, adopt, and file an Urban Water Management Plan (UWMP) with the California
Department of Water Resources (DWR) every five years. The purpose of the UWMP is
to update the existing and planned water supplies, maintain efficient use of urban water
supplies, continue to promote water conservation, ensure sufficient water supplies are
available, and provide a mechanism for response during drought conditions. The DWR
reviews the submitted plans to assure compliance requirements identified in the Urban
Water Management Planning Act (Division 6 Part 2.6 of the Water Code § 10610 - 10656).
The 2020 UWMP is required to be updated and submitted to the DWR by July 1, 2021.

What is the Water Supply Contingency Plan?
The Water Shortage Contingency Plan (WSCP) is a newly required strategic planning
document designed to prepare for and respond to water shortages. The draft WSCP is
included as Attachment B. This WSCP complies with California Water Code (Water Code)
Section 10632, which requires that every urban water supplier (Supplier) shall prepare
and adopt a WSCP as part of its Urban Water Management Plan (UWMP). This level of
detailed planning and preparation is intended to help maintain reliable supplies and
reduce the impacts of supply interruptions.
Similar to the City's Municipal Code Chapter 14.16 Water Conservation and Supply
Regulations, the WSCP includes management features with structured steps to respond
to actual conditions by allowing for efficient management of a shortage with predictability
and accountability. Because the WSCP is a requirement and is similar to the City's
existing Water Conservation and Supply Regulations, (i.e. City Municipal Code section
14.16) the City of Newport Beach (City) submitted a crosswalk between the two plans.
This meets the State's requirement of developing and submitting a WSCP, without having
to update the City's existing Municipal Code at this time. Following approval of the UWMP
and WSCP, an update to the Municipal Code is planned for City Council consideration
this summer.
What is the Addendum to 2015 UWMP to add Appendix J Reduced Delta Reliance
Reporting?
The noted Addendum (Attachment C) is complicated. In summary, the Addendum
certifies that an agency's actions as a recipient of water from Metropolitan Water District
of Southern California will be consistent with applicable Delta Plan policies of the
Sacramento -San Joaquin Delta Reform Act of 2009. State and local public agencies are
required to certify this, and all local public agencies are submitting this Addendum to their
2015 UWMP. The 2020 UWMP meets the requirement and will not require an Addendum
on this matter in the future.
City's Preparations
The City, along with 23 other local agencies, is participating in a cooperative agreement
with the Municipal Water District of Orange County (MWDOC) to update/develop UWMPs
for individual agencies. Due to the similarity of regional information required for the plan,
along with shared requirements mandated from each water source entity, this joint effort
minimizes consultant costs through economies of scale. The resulting UWMPs are
tailored to the individual agencies and meet all elements required by the California Water
Code. The City and the 23 other local agencies contracted with Arcadis in August 2020
to assist in the preparation of each agencies' 2020 UWMP and WSCP.

The City's UWMP is a comprehensive document that presents an evaluation of our water
supply reliability over a long-term (20-25 year) horizon. Much of our water supply reliability
comes from imported water and groundwater managed by other agencies. In summary,
the 2020 UWMP is a planning and verification document. The City meets State
requirements through planned water resource needs, our water reliability assessment,
our water use efficiency programs, and our planned strategies to mitigate water shortage
conditions.
The UWMP document is voluminous and as part of this staff report only the title, table of
contents and executive summary has been attached (Attachment A). The full-length
UWMP document is available on the City's website at the link provided below. It will be
available there during the next five-year operational period.
2020 UWMP Document
FISCAL IMPACT:
The adopted budget includes sufficient funding for the cost to prepare the plan. It was
expensed to the 701 Water Enterprise Fund professional services account.
Implementation is carried out and funded through the Water Fund's operational and
capital improvement accounts. Without an approved UWMP, the City would jeopardize
State grant funding, and could be subject to penalties.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this action is not subject to the California
Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not
result in a direct or reasonably foreseeable indirect physical change in the environment)
and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA
Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no
potential for resulting in physical change to the environment, directly or indirectly.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of
the meeting at which the City Council considers the item).

Newport Beach 2020 Urban Water Management Plan
EXECUTIVE SUMMARY
INTRODUCTION AND UWMP OVERVIEW
The City of Newport Beach (City) prepared this 2020 Urban Water Management Plan (UWMP) to submit
to the California Department of Water Resources (DWR) to satisfy the UWMP Act of 1983 (UWMP Act or
Act) and subsequent California Water Code (Water Code) requirements. The City is a retail water
supplier that provides water to its residents and other customers using the imported potable water supply
obtained from its regional wholesaler, Municipal Water District of Orange County (MWDOC), local
groundwater from the Orange County Groundwater Basin (OC Basin), and recycled water from the
Orange County Water District (OCWD).
UWMPs are comprehensive documents that present an evaluation of a water supplier's reliability over a
long-term (20-25 year) horizon. This 2020 UWMP provides an assessment of the present and future
water supply sources and demands within the City's service area. It presents an update to the 2015
UWMP on the City's water resource needs, water use efficiency programs, water reliability assessment
and strategies to mitigate water shortage conditions. It also presents a new 2020 Water Shortage
Contingency Plan (WSCP) designed to prepare for and respond to water shortages. This 2020 UWMP
contains all elements to meet compliance of the new requirements of the Act as amended since 2015.
UWMP PREPARATION
The City coordinated the preparation of this 2020 UWMP with other key entities, including MWDOC
(regional wholesaler of imported water for Orange County), Metropolitan Water District of southern
California (MET) (regional wholesaler for Southern California and the direct supplier of imported water to
MWDOC), and OCWD (OC Basin manager and provider of recycled water in north Orange County). The
City also coordinated with other entities, which provided valuable data for the analyses prepared in this
UWMP, such as the Center for Demographic Research (CDR) at California State University Fullerton for
population projections, through MWDOC's assistance.
SYSTEM DESCRIPTION
The City was incorporated on September 1, 1906 and is governed by a seven -member City Council which
operates under a Council -Manager format of government. The City Utilities Department and the Public
Works Department work collaboratively to provide water to the customers.
The City's water service area covers about 11 square miles located along the Orange County coast of
Southern California. The water service area covers most of the City's boundaries with the remaining
areas served by Irvine Ranch Water District (IRWD) and Mesa Water District (Mesa Water).
The City operates a wellfield with a total capacity of 10,900 gallons per minute (gpm), 15 recycled water
connections, 6 inter -agency emergency interconnections and manages about 300 -mile water mains
system with 26,765 service connections.
Lying in the South Coast Air Basin (SCAB), its climate is characterized by Southern California's
"Mediterranean" climate with mild winters, warm summers and moderate rainfall. In terms of land use, the
City is almost built out with predominantly single and multi -family residential units. Moving forward, the
City will continue planning for its Regional Housing Needs Assessment (RHNA) allocation and future
planned developments beyond 2020 will mainly include addition of institutional, commercial and a few

Newport Beach 2020 Urban Water Management Plan
residential units. The current population of 61,916 is projected to increase by only 4.8% over the next
25 years.
WATER USE CHARACTERIZATION
Water use within the City's service area has been relatively stable in the past decade with an annual
average of 15,413 AF. In this period, potable and non -potable water use accounted for an average of
97% and 3% of total City water use, respectively. In FY2019-20, the City's water use was 14,492 AF of
potable water (groundwater and imported) and 513 AF of direct recycled water for landscape irrigation.
In FY2019-20, the City's potable water use profile was comprised of 58.9% residential use,
18.2% commercial, institutional, and industrial (CII) and 18.1% large landscape/irrigation, with
non -revenue water and other uses comprising about 4.8%.
Water Use Projections: 5 -year and 25 -year
The City's service area is almost completely built -out and is projected to add minimum land use and small
population increase. Water demand is likely to decrease less than 1 % over the next 5 years. In the longer
term, water demand is projected to increase 5.2% from 2025 through 2045. The projected water use for
2045 is 15,103 AF for potable water and 542 AF for recycled water.
This demand projection considers such factors as current and future demographics, future water use
efficiency measures, and long term weather variability.
CONSERVATION TARGET COMPLIANCE
Retail water suppliers are required to comply with the requirements of Water Conservation Act of 2009,
also known as SBx7-7 (Senate Bill 7 as part of the Seventh Extraordinary Session), which was signed
into law in 2010 and requires the State of California to reduce urban water use by 20% by 2020 from a
2013 baseline.
The retail water suppliers can comply individually or as a region in collaboration with other retail water
suppliers, in order to be eligible for water related state grants and loans. The City is part of the Orange
County 20x2020 Regional Alliance created in collaboration with MWDOC, its retail member agencies as
well as the Cities of Anaheim, Fullerton, and Santa Ana. The Alliance was created to assist OC retail
agencies in complying with SBx7-7
The City met its 2020 water use target and is in compliance with SBx7-7; the actual 2020 consumption
was 160 gallons per capita per day (GPCD), which is below its 2020 target of 207 GPCD.
WATER SUPPLY CHARACTERIZATION
The City meets all of its demands with a combination of imported water, local groundwater, and recycled
water. The City works together with two primary agencies, MWDOC and OCWD to ensure a safe and
reliable water supply that will continue to serve the community in periods of drought and shortage. The
sources of imported water supplies include water from the Colorado River and the State Water Project
(SWP) provided by MET and delivered through MWDOC.
The City's main source of water supply is groundwater from the OC Basin. Imported water and recycled
water supplement the City's water supply portfolio. In FY 2019-20, the City's water supplies consisted of
68% groundwater, 28.5% imported water, and 3.5% recycled water.
arcadis.com
ES -2
14-17
Newport Beach 2020 Urban Water Management Plan
It is projected that by 2045, the water supply portfolio will shift to 82% groundwater, 14.5% imported water,
and 3.5% recycled water. Note that these representations of supply match the projected demand. The City
can purchase more MET water through MWDOC, should the need arise.
The City does not own or operate wastewater treatment facilities but owns and operates the wastewater
collection system in its service area that sends all wastewater to OC San for treatment and disposal. The
City benefits from its direct and indirect uses of recycled water. OCWD's Green Acres Project (GAP)
produces recycled water for direct non -potable reuses such as landscape irrigation. OCWD's
Groundwater Replenishment System (GWRS) produces recycled water for indirect potable reuse (IPR)
through the replenishment of the OC Basin.
WATER SERVICE RELIABILITY AND DROUGHT RISK ASSESSMENT
Every urban water supplier is required to assess the reliability of their water service to its customers under
a normal year, a single dry year, and a drought period lasting five consecutive years. The water service
reliability assessment compares projected supply to projected demand for the three hydrological
conditions between 2025 and 2045. Factors affecting reliability, such as climate change and regulatory
impacts, are accounted for as part of the assessment.
The City depends on a combination of imported and local supplies to meet its water demands and has
taken numerous steps to ensure it has adequate supplies. MET's and MWDOC's 2020 UWMPs conclude
that they can meet full-service demands of their member agencies through 2045 during normal years,
single -dry years, and multiple -dry years. Consequently, the City is projected to meet full-service demands
through 2045 for all scenarios, due to diversified supply and conservation measures.
The Drought Risk Assessment (DRA) evaluates the City's near-term ability to supply water assuming the
City is experiencing a drought over the next five years. Even under the assumption of a drought over the
next five years, MET's 2020 UWMP concludes a surplus of water supplies would be available to all of its
Member Agencies, including MWDOC and in effect, the City, should the need for additional supplies arise
to close any local supply gap. Additionally, the City partakes in various efforts to reduce its reliance on
imported water supplies such as increasing the use of local groundwater and recycled water supplies.
WATER SHORTAGE CONTINGENCY PLANNING
Water shortage contingency planning is a strategic planning process that the City engages to prepare
for and respond to water shortages. A water shortage, when water supply available is insufficient to meet
the normally expected customer water use at a given point in time, may occur due to a number of
reasons, such as water supply quality changes, climate change, drought, and catastrophic events
(e.g., earthquake). The City's WSCP provides real-time water supply availability assessment and
structured steps designed to respond to actual conditions. This level of detailed planning and preparation
will help maintain reliable supplies and reduce the impacts of supply interruptions.
The WSCP serves as the operating manual that the City will use to prevent catastrophic service
disruptions through proactive, rather than reactive, mitigation of water shortages. The WSCP contains the
processes and procedures that will be deployed when shortage conditions arise so that the City's
governing body, its staff, and its retail agencies can easily identify and efficiently implement
arcadis.com
ES -3
14-18
Newport Beach 2020 Urban Water Management Plan
pre -determined steps to mitigate a water shortage to the level appropriate to the degree of water shortfall
anticipated.
DEMAND MANAGEMENT MEASURES
The City, along with other Retail water agencies throughout Orange County, recognizes the need to use
existing water supplies efficiently. This ethic of efficient water use has evolved as a result of the
development and implementation of water use efficiency programs that make economic sense while
reflecting responsible stewardship of the region's water resources. The City works closely with MWDOC
to promote regional efficiency by participating in the regional water savings programs, leveraging
MWDOC local program assistance, and applying the findings of MWDOCs research and evaluation
efforts. This approach helps minimize confusion to consumers by providing the same programs with the
same participation guidelines, maintains a consistent message to the public to use water efficiently, and
provides support to retail water agencies with MWDOC serving as program administrator for the region.
PLAN ADOPTION, SUBMITTAL, AND IMPLEMENTATION
The Water Code requires the UWMP to be adopted by the Supplier's governing body. Before the
adoption of the UWMP, the City notified the public and the cities and counties within its service area per
the Water Code and held a public hearing to receive input from the public on the UWMP. Post adoption,
the City submitted the UWMP to DWR and the other key agencies and will make it available for public
review no later than 30 days after filing with DWR.

INTRODUCTION AND WSCP OVERVIEW
The Water Shortage Contingency Plan (WSCP) is a strategic planning document designed to prepare for
and respond to water shortages. This WSCP complies with California Water Code (Water Code) Section
10632, which requires that every urban water supplier (Supplier) shall prepare and adopt a WSCP as part
of its Urban Water Management Plan (UWMP). This level of detailed planning and preparation is intended
to help maintain reliable supplies and reduce the impacts of supply interruptions.
The WSCP is the City of Newport Beach (City)'s operating manual that is used to prevent catastrophic
service disruptions through proactive, rather than reactive, management. A water shortage, when water
supply available is insufficient to meet the normally expected customer water use at a given point in time,
may occur due to a number of reasons, such as drought, climate change, and catastrophic events. This
plan provides a structured guide for the City to deal with water shortages, incorporating prescriptive
information and standardized action levels, along with implementation actions in the event of a
catastrophic supply interruption. This way, if and when shortage conditions arise, the City's governing
body, its staff, and the public can easily identify and efficiently implement pre -determined steps to
manage a water shortage. A well -structured WSCP allows real-time water supply availability assessment
and structured steps designed to respond to actual conditions, to allow for efficient management of any
shortage with predictability and accountability.
The WSCP also describes the City's procedures for conducting an Annual Water Supply and Demand
Assessment (Annual Assessment) that is required by Water Code Section 10632.1 and is to be submitted
to the California Department of Water Resources (DWR) on or before July 1 of each year, or within 14
days of receiving final allocations from the State Water Project (SWP), whichever is later. The City's 2020
WSCP is included as an appendix to its 2020 UWMP which will be submitted to DWR by July 1, 2021.
However, this WSCP is created separately from the City's 2020 UWMP and can be amended, as needed,
without amending the UWMP. Furthermore, the Water Code does not prohibit a Supplier from taking
actions not specified in its WSCP, if needed, without having to formally amend its UWMP or WSCP.
1.1 Water Shortage Contingency Plan Requirements and
Organization
The WSCP provides the steps and water shortage response actions to be taken in times of water
shortage conditions. WSCP has prescriptive elements, such as an analysis of water supply reliability; the
water shortage response actions for each of the six standard water shortage levels that correspond to
water shortage percentages ranging from 10% to greater than 50%; an estimate of potential to close
supply gap for each measure; protocols and procedures to communicate identified actions for any current
or predicted water shortage conditions; procedures for an Annual Assessment; monitoring and reporting
requirements to determine customer compliance; and reevaluation and improvement procedures for
evaluating the WSCP.
This WSCP is organized into three main sections, with Section 3 aligned with the Water Code Section
16032 requirements.
14-27
Section 1 Introduction and WSCP Overview gives a summary of the WSCP fundamentals.
Section 2 Background provides a background on the City's water service area.
Section 3 Water Shortage Contingency Preparedness and Response Planning.
Section 3.1 Water Supply Reliability Analysis provides a summary of the water supply analysis and
water reliability findings from the 2020 UWMP.
Section 3.2 Annual Water Supply and Demand Assessment Procedures provide a description of
procedures to conduct and approve the Annual Assessment.
Section 3.3 Six Standard Water Shortage Stages explains the WSCP's six standard water shortage
levels corresponding to progressive ranges of up to 10, 20, 30, 40, 50, and more than 50% shortages.
Section 3.4 Shortage Response Actions describes the WSCP's shortage response actions that align
with the defined shortage levels.
Section 3.5 Communication Protocols addresses communication protocols and procedures to inform
customers, the public, interested parties, and local, regional, and state governments, regarding any
current or predicted shortages and any resulting shortage response actions.
Section 3.6 Compliance and Enforcement describes customer compliance, enforcement, appeal, and
exemption procedures for triggered shortage response actions.
Section 3.7 Legal Authorities is a description of the legal authorities that enable the City to implement
and enforce its shortage response actions.
Section 3.8 Financial Consequences of the WSCP provides a description of the financial
consequences of and responses for drought conditions.
Section 3.9 Monitoring and Reporting describes monitoring and reporting requirements and procedures
that ensure appropriate data is collected, tracked, and analyzed for purposes of monitoring customer
compliance and to meet state reporting requirements.
Section 3.10 WSCP Refinement Procedures addresses reevaluation and improvement procedures for
monitoring and evaluating the functionality of the WSCP.
Section 3.11 Special Water Feature Distinction is a required definition for inclusion in a WSCP per the
Water Code.
Section 3.12 Plan Adoption, Submittal, and Implementation provides a record of the process the City
followed to adopt and implement its WSCP.
1.2 Integration with Other Planning Efforts
As a retail water supplier in Orange County, the City considered other key entities in the development of
this WSCP, including the Municipal Water District of Orange County ([MWDOC] (regional wholesale
supplier)), the Metropolitan Water District of Southern California ([MET] (regional wholesaler for Southern
California and the direct supplier of imported water to MWDOC)), and Orange County Water District
([OCWD] (Orange County Groundwater Basin manager and provider of recycled water in North Orange
14-28
County)). As a MWDOC member agency, the City also developed this WSCP with input from several
coordination efforts led by MWDOC.
Some of the key planning and reporting documents that were used to develop this WSCP are:
MWDOC's 2020 UWMP provides the basis for the projections of the imported supply availability
over the next 25 years for the City's service area.
MWDOC's 2020 WSCP provides a water supply availability assessment and structured steps
designed to respond to actual conditions that will help maintain reliable supplies and reduce the
impacts of supply interruptions.
• 2021 Orange County Water Demand Forecast for MWDOC and OCWD Technical
Memorandum (Demand Forecast TM) provides the basis for water demand projections for
MWDOC's member agencies as well as Anaheim, Fullerton, and Santa Ana.
• MET's 2020 Integrated Water Resources Plan (IRP) is a long-term planning document to
ensure water supply availability in Southern California and provides a basis for water supply
reliability in Orange County.
• MET's 2020 UWMP was developed as a part of the 2020 IRP planning process and was used by
MWDOC as another basis for the projections of supply capability of the imported water received
from MET.
• MET's 2020 WSCP provides a water supply assessment and guide for MET's intended actions
during water shortage conditions.
• OCWD's 2019-20 Engineer's Report provides information on the groundwater conditions and
basin utilization of the Orange County Groundwater Basin (OC Basin).
• OCWD's 2017 Basin 8-1 Alternative is an alternative to the Groundwater Sustainability Plan
(GSP) for the OC Basin and provides significant information related to sustainable management
of the basin in the past and hydrogeology of the basin, including groundwater quality and basin
characteristics.
• 2020 Local Hazard Mitigation Plan (HMP) provides the basis for the seismic risk analysis of the
water system facilities.
• Orange County Local Agency Formation Commission's 2020 Municipal Service Review for
MWDOC Report provides a comprehensive service review of the municipal services provided by
MWDOC.
• Water Master Plan and Sewer Master Plan of the City provides information on water
infrastructure planning projects and plans to address any required water system improvements.
• Groundwater Management Plans provide the groundwater sustainability goals for the basins in
the MWDOC's service area and the programs, actions, and strategies activities that support those
goals.

2 BACKGROUND INFORMATION
The City was incorporated on September 1, 1906 and the current City Charter was adopted in 1954. The
City is governed by a seven -member City Council which operates under a Council -Manager format of
government. The City Utilities Department is responsible for the operation and maintenance of the City's
water, wastewater, water quality, and storm drain systems, as well as and other municipal utilities within
the City. The City's Public Works Department is responsible for engineering services including capital
project delivery, environmental services, and transportation and development services. The two
departments work collaboratively to provide water to the customers. The City is known for its fine
residential areas, modern shopping facilities, strong business community and quality school system.
2.1 City Service Area
The City provides water to approximately 11 square miles of land area located along the Orange County
coast of Southern California. The City is bounded to the West by the Pacific Ocean, to the North by the
cities of Huntington Beach and Costa Mesa, to the South by Laguna Beach, and to the East by Irvine.
The water service area covers most of the City's boundaries with the remaining areas served by
IRWD and Mesa Water as shown on Figure 2-1. The City operates a wellfield with a total capacity of
10,900 gallons per minute, 15 recycled water connections, 6 inter -agency emergency interconnections
and manages about 300 -mile water mains system with 26,765 service connections.

Although the City supplements its water supply portfolio with recycled water, the WSCP only applies to its
potable water supply. The City is directly involved in wastewater services through its ownership and
operation of the wastewater collection system in its service area and sends all collected wastewater to
Orange County Sanitation District (OC San) for treatment and disposal. The City sells and distributes
OCWD Green Acres Project (GAP) water to recycled water customers, as detailed in Section 6.6 of the
City's 2020 UWMP (Newport Beach, 2021). The City will determine the recycled water demand reduction
actions for recycled water based on the availability of supply and to meet necessary wastewater
discharge permit requirements.
2.2 Relationship to Wholesalers
MET: MET is the largest water wholesaler for domestic and municipal uses in California, serving
approximately 19 million customers. MET wholesales imported water supplies to 26 member cities and
water districts in six Southern California counties. Its service area covers the Southern California coastal
plain, extending approximately 200 miles along the Pacific Ocean from the City of Oxnard in the north to
the international boundary with Mexico in the south. This encompasses 5,200 square miles and includes
portions of Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Ventura counties.
Approximately 85% of the population from the aforementioned counties reside within MET's boundaries.
14-31
MET is governed by a Board of Directors comprised of 38 appointed individuals with a minimum of one
representative from each of MET's 26 member agencies. The allocation of directors and voting rights are
determined by each agency's assessed valuation. Each member of the Board shall be entitled to cast one
vote for each ten million dollars ($10,000,000) of assessed valuation of property taxable for district
purposes, in accordance with Section 55 of the Metropolitan Water District Act (Metropolitan Act).
Directors can be appointed through the chief executive officer of the member agency or by a majority vote
of the governing board of the agency. Directors are not compensated by MET for their service.
MET is responsible for importing water into the region through its operation of the Colorado River
Aqueduct (CRA) and its contract with the State of California for SWP supplies. Member agencies receive
water from MET through various delivery points and pay for service through a rate structure made up of
volumetric rates, capacity charges and readiness to serve charges. Member agencies provide estimates
of imported water demand to MET annually in April regarding the amount of water they anticipate they will
need to meet their demands for the next five years.
MWDOC: In Orange County, MWDOC and the Cities of Anaheim, Fullerton, and Santa Ana are MET
member agencies that purchase imported water directly from MET. Furthermore, MWDOC purchases
both treated potable and untreated water from MET to supplement its retail agencies' local supplies.
The City is one of MWDOC's 28 member agencies receiving imported water from MWDOC. The City's
location within MWDOC's service area is shown on Figure 2-2.

Relationship with Wholesaler Water Shortage Planning
The WSCP is designed to be consistent with MET's Water Shortage and Demand Management (WSDM)
Plan, MWDOC's Water Supply Allocation Plan (WSAP), and other emergency planning efforts as
described below. MWDOC's WSAP is integral to the WSCP's shortage response strategy in the event
that MET or MWDOC determines that supply augmentation (including storage) and lesser demand
reduction measures would not be sufficient to meet a projected shortage levels needed to meet demands.
2.3.1 MET Water Surplus and Drought Management Plan
MET evaluates the level of supplies available and existing levels of water in storage to determine the
appropriate management stage annually. Each stage is associated with specific resource management
actions to avoid extreme shortages to the extent possible and minimize adverse impacts to retail
customers should an extreme shortage occur. The sequencing outlined in the WSDM Plan reflects
anticipated responses towards MET's existing and expected resource supply portfolio options.
Surplus stages occur when net annual deliveries can be made to water storage programs. Under the
WSDM Plan, there are four surplus management stages that provides a framework for actions to take for
surplus supplies. Deliveries in Diamond Valley Lake (DVL) and in SWP terminal reservoirs continue
through each surplus stage provided there is available storage capacity. Withdrawals from DVL for
regulatory purposes or to meet seasonal demands may occur in any stage.
The WSDM Plan distinguishes between shortages, severe shortages, and extreme shortages. The
differences between each term are listed below.
• Shortage: MET can meet full-service demands and partially meet or fully meet interruptible demands
using stored water or water transfers as necessary.
• Severe Shortage: MET can meet full-service demands only by using stored water, transfers, and
possibly calling for extraordinary conservation.
• Extreme Shortage: MET must allocate available supply to full-service customers.
There are six shortage management stages to guide resource management activities. These stages are
defined by shortfalls in imported supply and water balances in MET's storage programs. When MET must
make net withdrawals from storage to meet demands, it is considered to be in a shortage condition.
Figure 2-3 gives a summary of actions under each surplus and shortage stages when an allocation plan
is necessary to enforce mandatory cutbacks. The goal of the WSDM plan is to avoid Stage 6, an extreme
shortage (MET, 1999).

MET's Board of Directors adopted a Water Supply Condition Framework in June 2008 in order to
communicate the urgency of the region's water supply situation and the need for further water
conservation practices. The framework has four conditions, each calling increasing levels of conservation.
Descriptions for each of the four conditions are listed below:
• Baseline Water Use Efficiency: Ongoing conservation, outreach, and recycling programs to achieve
permanent reductions in water use and build storage reserves.
• Condition 1 Water Supply Watch: Local agency voluntary dry -year conservation measures and use of
regional storage reserves.
• Condition 2 Water Supply Alert: Regional call for cities, counties, member agencies, and retail water
agencies to implement extraordinary conservation through drought ordinances and other measures to
mitigate use of storage reserves.
• Condition 3 Water Supply Allocation: Implement MET's WSAP.
As noted in Condition 3, should supplies become limited to the point where imported water demands
cannot be met, MET will allocate water through the WSAP (MET, 2021 a).
2.3.2 MET Water Supply Allocation Plan
MET's imported supplies have been impacted by a number of water supply challenges as noted earlier. In
case of extreme water shortage within the MET service area is the implementation of its WSAP.
14-35
MET's Board of Directors originally adopted the WSAP in February 2008 to fairly distribute a limited
amount of water supply and applies it through a detailed methodology to reflect a range of local
conditions and needs of the region's retail water consumers (MET, 2021 a).
The WSAP includes the specific formula for calculating member agency supply allocations and the key
implementation elements needed for administering an allocation. MET's WSAP is the foundation for the
urban water shortage contingency analysis required under Water Code Section 10632 and is part of
MET's 2020 UWMP.
MET's WSAP was developed in consideration of the principles and guidelines in MET's 1999 WSDM Plan
with the core objective of creating an equitable "needs -based allocation." The WSAP's formula seeks to
balance the impacts of a shortage at the retail level while maintaining equity on the wholesale level for
shortages of MET supplies of up to or if necessary greater than 50% cutback. The formula takes into
account a number of factors, such as the impact on retail customers, growth in population, changes in
supply conditions, investments in local resources, demand hardening aspects of water conservation
savings, recycled water, extraordinary storage and transfer actions, and groundwater imported water
needs.
The formula is calculated in three steps: 1) based period calculations, 2) allocation year calculations, and
3) supply allocation calculations. The first two steps involve standard computations, while the third step
contains specific methodology developed for the WSAP.
Step 1: Base Period Calculations — The first step in calculating a member agency's water supply
allocation is to estimate their water supply and demand using a historical based period with established
water supply and delivery data. The base period for each of the different categories of supply and
demand is calculated using data from the two most recent non -shortage years.
Step 2: Allocation Year Calculations — The next step in calculating the member agency's water supply
allocation is estimating water needs in the allocation year. This is done by adjusting the base period
estimates of retail demand for population growth and changes in local supplies
Step 3: Supply Allocation Calculations — The final step is calculating the water supply allocation for
each member agency based on the allocation year water needs identified in Step 2.
In order to implement the WSAP, MET's Board of Directors makes a determination on the level of the
regional shortage, based on specific criteria, typically in April. The criteria used by MET includes, current
levels of storage, estimated water supplies conditions, and projected imported water demands. The
allocations, if deemed necessary, go into effect in July of the same year and remain in effect for a 12 -
month period. The schedule is made at the discretion of the Board of Directors (MET, 2021 b).
As demonstrated by the findings in MET's 2020 UWMP both the Water Reliability Assessment and the
Drought Risk Assessment (DRA) demonstrate that MET is able to mitigate the challenges posed by
hydrologic variability, potential climate change, and regulatory risk on its imported supply sources through
the significant storage capabilities it has developed over the last two decades, both dry -year and
emergency storage (MET, 2021 a).
Although MET's 2020 UWMP forecasts that MET will be able to meet projected imported demands
throughout the projected period from 2025 to 2045, uncertainty in supply conditions can result in MET
needing to implement its WSAP to preserve dry -year storage and curtail demands (MET, 2021 b).
14-36
2.3.3 MWDOC Water Supply Allocation Plan
To prepare for the potential allocation of imported water supplies from MET, MWDOC worked
collaboratively with its 28 retail agencies to develop its own WSAP that was adopted in January 2009 and
amended in 2016. The MWDOC WSAP outlines how MWDOC will determine and implement each of its
retail agency's allocation during a time of shortage.
The MWDOC WSAP uses a similar method and approach, when reasonable, as that of the MET's WSAP.
However, MWDOC's plan remains flexible to use an alternative approach when MET's method produces
a significant unintended result for the member agencies. The MWDOC WSAP model follows five basic
steps to determine a retail agency's imported supply allocation.
Step 1: Determine Baseline Information — The first step in calculating a water supply allocation is to
estimate water supply and demand using a historical based period with established water supply and
delivery data. The base period for each of the different categories of demand and supply is calculated
using data from the last two non -shortage years.
Step 2: Establish Allocation Year Information — In this step, the model adjusts for each retail agency's
water need in the allocation year. This is done by adjusting the base period estimates for increased retail
water demand based on population growth and changes in local supplies.
Step 3: Calculate Initial Minimum Allocation Based on MET's Declared Shortage Level — This step
sets the initial water supply allocation for each retail agency. After a regional shortage level is established,
MWDOC will calculate the initial allocation as a percentage of adjusted Base Period Imported water
needs within the model for each retail agency.
Step 4: Apply Allocation Adjustments and Credits in the Areas of Retail Impacts and
Conservation— In this step, the model assigns additional water to address disparate impacts at the retail
level caused by an across-the-board cut of imported supplies. It also applies a conservation credit given
to those agencies that have achieved additional water savings at the retail level as a result of successful
implementation of water conservation devices, programs and rate structures.
Step 5: Sum Total Allocations and Determine Retail Reliability — This is the final step in calculating a
retail agency's total allocation for imported supplies. The model sums an agency's total imported
allocation with all of the adjustments and credits and then calculates each agency's retail reliability
compared to its Allocation Year Retail Demand.
The MWDOC WSAP includes additional measures for plan implementation, including the following
(MWDOC, 2016):
• Appeal Process — An appeals process to provide retail agencies the opportunity to request a change
to their allocation based on new or corrected information. MWDOC anticipates that under most
circumstances, a retail agency's appeal will be the basis for an appeal to MET by MWDOC.
Melded Allocation Surcharge Structure — At the end of the allocation year, MWDOC would only
charge an allocation surcharge to each retail agency that exceeded their allocation if MWDOC
exceeds its total allocation and is required to pay a surcharge to MET. MET enforces allocations to
retail agencies through an allocation surcharge to a retail agency that exceeds its total annual
allocation at the end of the 12 -month allocation period. MWDOC's surcharge would be assessed
14-37
according to the retail agency's prorated share (AF over usage) of MWDOC amount with MET.
Surcharge funds collected by MET will be invested in its Water Management Fund, which is used to
in part to fund expenditures in dry -year conservation and local resource development.
Tracking and Reporting Water Usage — MWDOC will provide each retail agency with water use
monthly reports that will compare each retail agency's current cumulative retail usage to their
allocation baseline. MWDOC will also provide quarterly reports on its cumulative retail usage versus
its allocation baseline.
• Timeline and Option to Revisit the Plan — The allocation period will cover 12 consecutive months
and the Regional Shortage Level will be set for the entire allocation period. MWDOC only anticipates
calling for allocation when MET declares a shortage; and no later than 30 days from MET's
declaration will MWDOC announce allocation to its retail agencies.

3 WATER SHORTAGE CONTINGENCY PREPAREDNESS AND
RESPONSE PLANNING
The City's WSCP is a detailed guide of how the City intends to act in the case of an actual water shortage
condition. The WSCP anticipates a water supply shortage and provides pre -planned guidance for managing and
mitigating a shortage. Regardless of the reason for the shortage, the WSCP is based on adequate details of
demand reduction and supply augmentation measures that are structured to match varying degrees of shortage
will ensure the relevant stakeholders understand what to expect during a water shortage situation.
3.1 Water Supply Reliability Analysis
Per Water Code Section 10632 (a)(1), the WSCP shall provide an analysis of water supply reliability conducted
pursuant to Water Code Section 10635, and the key issues that may create a shortage condition when looking at
the City's water asset portfolio.
Understanding water supply reliability, factors that could contribute to water supply constraints, availability of
alternative supplies, and what effect these have on meeting customer demands provides the City with a solid
basis on which to develop appropriate and feasible response actions in the event of a water shortage. In the 2020
UWMP, the City conducted a Water Reliability Assessment to compare the total water supply sources available to
the water supplier with long-term projected water use over the next 20 years, in five-year increments, for a normal
water year, a single dry water year, and a drought lasting five consecutive water years (Newport Beach, 2021).
The City also conducted a DRA to evaluate a drought period that lasts five consecutive water years starting from
the year following when the assessment is conducted. An analysis of both assessments determined that the City
is capable of meeting all customers' demands from 2021 through 2045 for a normal year, a single dry year, and a
drought lasting five consecutive years with significant imported water supplemental dedicated drought supplies
from MWDOC/MET and ongoing conversation program efforts. The City receives the majority of its water supply
from groundwater from the OC Basin, as well as supplemental supplies from local recycled water from the OCWD
GAP that adds reliability for non -potable water demand.
As a result, there is no projected shortage condition due to drought that will trigger customer demand reduction
actions until MWDOC notifies the City of insufficient imported supplies. More information is available in the City's
2020 UWMP Section 6 and 7 (Newport Beach, 2021).
3.2 Annual Water Supply and Demand Assessment Procedures
Per Water Code Section 10632.1, the City will conduct an Annual Assessment pursuant to subdivision (a) of
Section 10632 and by July 1 st of each year, beginning in 2022, submit an Annual Assessment with information for
anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and
communication actions consistent with the Supplier's WSCP.
The City must include in its WSCP the procedures used for conducting an Annual Assessment. The Annual
Assessment is a determination of the near-term outlook for supplies and demands and how a perceived shortage
may relate to WSCP shortage stage response actions in the current calendar year. This determination is based
on information available to the City at the time of the analysis. Starting in 2022, the Annual Assessment will be
due by July 1 of every year.
14-39
This section documents the decision-making process required for formal approval of the City's Annual
Assessment determination of water supply reliability each year and the key data inputs and the methodologies
used to evaluate the water system reliability for the coming year, while considering that the year to follow would
be considered dry.
3.2.1 Decision -Making Process
The following decision-making process describes the functional steps that the City will take to formally approve
the Annual Assessment determination of water supply reliability each year.
3.2.1.1 City Steps to Approve the Annual Assessment Determination
The Annual Assessment will be predicated on the OCWD Basin Production Percent (BPP) and on MWDOCs
Annual Assessment outcomes.
The City receives groundwater from OCWD. The OC Basin is not adjudicated and as such, pumping from the OC
Basin is managed through a process that uses financial incentives to encourage groundwater producers
(Producers) to pump a sustainable amount of water. The framework for the financial incentives is based on
establishing the BPP, the percentage of each Producer's total water supply that comes from groundwater pumped
from the OC Basin. The BPP is set uniformly for all Producers by OCWD on an annual basis by OCWD Board of
Directors. Based on the projected water demand and water modeled water supply, over the long-term, OCWD
anticipates sustainably supporting a BPP of 85%; however, volumes of groundwater and imported water may vary
depending on OCWD's actual BPP projections. A supply reduction that may result from the annual BPP projection
will be included in the Annual Assessment.
While the City's primary source of water is OCWD groundwater, any remaining source to meet retail demands
comes from the purchase of imported water from MWDOC. MWDOC surveys its member agencies annually for
anticipated water demands and supplies for the upcoming year. MWDOC utilizes this information to plan for the
anticipated imported water supplies for the MWDOC service area. This information is then shared and
coordinated with MET and is incorporated into their analysis of their service area's annual imported water needs.
Based on the year's supply conditions and WSDM actions, MET will present a completed Annual Assessment for
its member agencies' review from which they will then seek MET Board approval in April of each year.
Additionally, MET expects that any triggers or specific shortage response actions that result from the Annual
Assessment would be approved by their Board at that time. Based upon MET's Assessment and taking into
consideration information provided to MWDOC through the annual survey, MWDOC will provide an anticipated
estimate of imported supplies for the City to incorporate into the Annual Assessment.
The Annual Assessment findings will determine the approval process. If a shortage is identified, the Annual
Assessment will be taken to City Council for approval and formally submitted to DWR prior to the July 1 deadline.
If no shortage is identified, the Annual Assessment will be approved by the Utilities Director and formally
submitted to DWR prior to the July 1 deadline.

3.2.2 Data and Methodologies
The following paragraphs document the key data inputs and methodologies that are used to evaluate the water
system reliability for the coming year, while considering that the year to follow would be considered dry.
3.2.2.1 Assessment Methodology
The City will evaluate water supply reliability for the current year and one dry year for the purpose of the Annual
Assessment. The Annual Assessment determination will be based on considerations of unconstrained water
demand, local water supplies, MWDOC imported water supplies, planned water use, and infrastructure
considerations. The balance between projected in-service area supplies, coupled with MWDOC imported
supplies, and anticipated unconstrained demand will be used to determine what, if any, shortage stage is
expected under the WSCP framework as presented in Figure 3-2. The WSCP's standard shortage stages are
defined in terms of shortage percentages. Shortage percentages will be calculated by dividing the difference
between water supplies and unconstrained demand by total unconstrained demand. This calculation will be
performed separately for anticipated current year conditions and for assumed dry year conditions.

3.2.2.2 Locally Applicable Evaluation Criteria
Within Orange County, there are no significant local applicable criteria that directly affect reliability. Through the
years, the water agencies in Orange County have made tremendous efforts to integrate their systems to provide
flexibility to interchange with different sources of supplies. There are emergency agreements in place to ensure all
parts of the County have an adequate supply of water. In the northern part of the County, agencies have the
ability to meet a majority of their demands through groundwater with very little limitation, except for the OCWD
BPP.
The City will also continue to monitor emerging supply and demand conditions related to supplemental imported
water from MWDOC/MET and take appropriate actions consistent with the flexibility and adaptiveness inherent to
the WSCP. The City's Annual Assessment was based on the City's service area, water sources, water supply
reliability, and water use as described in Water Code Section 10631, including available data from state, regional,
or local agency population, land use development, and climate change projections within the service area of the
City. Some conditions that affect MWDOC's wholesale supply and demand, such as groundwater replenishment,
surface water and local supply production, can differ significantly from earlier projections throughout the year.
However, if a major earthquake on the San Andreas Fault occurs, it has the potential to damage all three key
regional water aqueducts and disrupt imported supplies for up to six months. The region would likely impose a
water use reduction ranging from 10-25% until the system is repaired. However, MET and MWDOC have taken
proactive steps to handle such disruption, such as constructing DVL, which mitigates potential impacts. DVL,
along with other local reservoirs, can store a six to twelve-month supply of emergency water (MET, 20211
3.2.2.3 Water Supply
As detailed in the City's UWMP, the City meets all of its customers' demands with a combination of local
groundwater, local recycled water, and imported water from MWDOC/MET. The City's main source of water
supply is groundwater from the OC Basin, with imported water from MET through MWDOC and recycled water
making up the rest of the City's water supply portfolio. In fiscal year (12019-20, the City relied on 68%
14-42
groundwater, 28% imported water, and 4% recycled water. It is projected that by 2045, the water supply portfolio
will change to approximately 82% groundwater, 15% imported water, and 3% recycled water, reflecting the
increase in OCWD's BPP to 85% beginning in 2025 (Newport Beach, 2021).
3.2.2.4 Unconstrained Customer Demand
The WSCP and Annual Assessment define unconstrained demand as expected water use prior to any projected
shortage response actions that may be taken under the WSCP. Unconstrained demand is distinguished from
observed demand, which may be constrained by preceding, ongoing, or future actions, such as emergency supply
allocations during a multi-year drought. WSCP shortage response actions to constrain demand are inherently
extraordinary; routine activities such as ongoing conservation programs and regular operational adjustments are
not considered as constraints on demands.
The City's DRA reveals that its supply capabilities are expected to balance anticipated total water use and supply,
assuming a five-year consecutive drought from FY 2020-21 through FY 2024-25 (Newport Beach, 2021). Water
demands in a five-year consecutive drought are calculated as a six percent increase in water demand above a
normal year for each year of the drought (CDM Smith, 2021).
3.2.2.5 Planned Water Use for Current Year Considering Dry Subsequent Year
Water Code Section 10632(a)(2)(B)(ii) requires the Annual Assessment to determine "current year available
supply, considering hydrological and regulatory conditions in the current year and one dry year."
The Annual Assessment will include two separate estimates of City's annual water supply and unconstrained
demand using: 1) current year conditions, and 2) assumed dry year conditions. Accordingly, the Annual
Assessment's shortage analysis will present separate sets of findings for the current year and dry year scenarios.
The Water Code does not specify the characteristics of a dry year, allowing discretion to the Supplier. The City
will use its discretion to refine and update its assumptions for a dry year scenario in each Annual Assessment as
information becomes available and in accordance with best management practices.
Supply and demand analyses for the single -dry year case was based on conditions affecting the SWP as this
supply availability fluctuates the most among MET's, and therefore MWDOC and the City's, sources of supply.
FY 2013-14 was the single driest year for SWP supplies with an allocation of 5% to Municipal and Industrial (M&I)
uses. Unique to this year, the 5% SWP allocation was later reduced to 0%, before ending up at its final allocation
of 5%, highlight the stressed water supplies for the year. Furthermore, on January 17, 2014 Governor Brown
declared the drought State of Emergency citing 2014 as the driest year in California history. Additionally, within
MWDOC's service area, precipitation for FY 2013-14 was the second lowest on record, with 4.37 inches of rain,
significantly impacting water demands.
The water demand forecasting model developed for the Demand Forecast TM isolated the impacts that weather
and future climate can have on water demand through the use of a statistical model. The impacts of hot/dry
weather condition are reflected as a percentage increase in water demands from the normal year condition
(average of FY 2017-18 and FY 2018-19). For a single dry year condition (FY 2013-14), the model projects a 6%
increase in demand for the OC Basin area where the City's service area is located (CDM Smith, 2021). Detailed
information of the model is included in the City's 2020 UWMP.
14-43
The City has documented that it is 100% reliable for single dry year demands from 2025 through 2045 with a
demand increase of 6% from normal demand with significant reserves held by MET, local groundwater supplies,
and conservation (Newport Beach, 2021).
3.2.2.6 Infrastructure Considerations
The Annual Assessment will include consideration of any infrastructure issues that may pertain to near-term water
supply reliability, including repairs, construction, and environmental mitigation measures that may temporarily
constrain capabilities, as well as any new projects that may add to system capacity. MWDOC closely coordinates
with MET and its member agencies, including the City, on any planned infrastructure work that may impact water
supply availability. Throughout each year, MET regularly carries out preventive and corrective maintenance of its
facilities within the MWDOC service area that may require shutdowns to inspect and repair pipelines and facilities
and support capital improvement projects. These shutdowns involve a high level of planning and coordination
between MWDOC, MWDOC's member agencies, and MET to ensure that major portions of the distribution
system are not out of service at the same time. Operational flexibility within MET's system and the cooperation of
member agencies allow shutdowns to be successfully completed while continuing to meet all system demands.
The City has a Capital Improvement Program schedule documented in its current Water Master Plan and will
consider planned projects and their potential impact on supply reliability in the Annual Assessment each year.
3.2.2.7 Other Factors
Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of manmade chemicals that includes
perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). PFAS compounds were once commonly
used in many products including, among many others, stain- and water-repellent fabrics, nonstick products (e.g.,
Teflon), polishes, waxes, paints, cleaning products, and fire -fighting foams. Beginning in the summer of 2019, the
California State Division of Drinking Water (DDW) began requiring testing for PFAS compounds in some
groundwater production wells in the OCWD area.
PFAS have been detected in one City well but are below the notification level. The City continues to monitor per
state testing requirements. PFAS are of particular concern for groundwater quality, and since the summer of
2019, DDW requires testing for PFAS compounds in some groundwater production wells in the OCWD area. In
February 2020, the DDW lowered its Response Levels (RL) for PFOA and PFOS to 10 and 40 parts per trillion
(ppt), respectively. The DDW recommends Producers not serve any water exceeding the RL — effectively making
the RL an interim Maximum Contaminant Level (MCL) while DDW undertakes administrative action to set a MCL.
In response to DDW's issuance of the revised RL, as of December 2020, approximately 45 wells in the OCWD
service area have been temporarily turned off until treatment systems can be constructed. As additional wells are
tested, OCWD expects this figure may increase to at least 70 to 80 wells. The state has begun the process of
establishing MCLs for PFOA and PFOS and anticipates these MCLs to be in effect by the Fall of 2023. OCWD
anticipates the MCLs will be set at or below the RLs.
In April 2020, OCWD as the groundwater basin manager, executed an agreement with the impacted Producers to
fund and construct the necessary treatment systems for production wells impacted by PFAS compounds. The
PFAS treatment projects includes the design, permitting, construction, and operation of PFAS removal systems
for impacted Producer production wells. Each well treatment system will be evaluated for use with either granular
activated carbon or ion exchange for the removal of PFAS compounds. These treatment systems utilize vessels
in a lead -lag configuration to remove PFOA and PFOS to less than 2 ppt (the current non -detect limit). Use of
14-44
these PFAS treatment systems are designed to ensure the groundwater supplied by Producer wells can be
served in compliance with current and future PFAS regulations. With financial assistance from OCWD, the
Producers will operate and maintain the new treatment systems once they are constructed.
To minimize expenses and provide maximum protection to the public water supply, OCWD initiated design,
permitting, and construction of the PFAS treatment projects on a schedule that allows rapid deployment of
treatment systems. Construction contracts were awarded for treatment systems for production wells in the City of
Fullerton and Serrano Water District in Year 2020. Additional construction contracts will likely be awarded in the
first and second quarters of 2021. OCWD expects the treatment systems to be constructed for most of the initial
45 wells above the RL within the next 2 to 3 years.
As additional data are collected and new wells experience PFAS detections at or near the current RL, and/or
above a future MCL, and are turned off, OCWD will continue to partner with the affected Producers and take
action to design and construct necessary treatment systems to bring the impacted wells back online as quickly as
possible.
Groundwater production in FY 2019-20 was expected to be approximately 325,000 AF but declined to 286,550 AF
primarily due to PFAS impacted wells being turned off around February 2020. OCWD expects groundwater
production to be in the area of 245,000 AF in FY 2020-21 due to the currently idled wells and additional wells
being impacted by PFAS and turned off. As PFAS treatment systems are constructed, OCWD expects total
annual groundwater production to slowly increase back to normal levels (310,000 to 330,000 AF) (OCWD, 2020).
3.3 Six Standard Water Shortage Levels
Per Water Code Section 10632 (a)(3)(A), the City must define the water shortage levels that represent shortages
from the normal reliability as determined in the Annual Assessment. The Water Code provides an option for
suppliers to align with six standard water shortage levels; however, the City has selected to retain its existing
water shortage levels as defined in City Code (Table 3-1). Table 3-2 shows the City's water shortage levels in
relationship to the six standard water shortage levels prescribed by statute. This crosswalk is intended to clearly
translate the City's water shortage levels to those mandated by statute.

Water Code Section 10632 (a)(4) requires the WSCP to specify shortage response actions that align with the
defined shortage levels. The City has defined specific shortage response actions that align with the defined
shortage levels in DWR Tables 8-2 and 8-3 (Appendix A). These shortage response actions were developed with
consideration to the system infrastructure and operations changes, supply augmentation responses, customer -
class or water use -specific demand reduction initiatives, and increasingly stringent water use prohibitions.
3.4.1 Demand Reduction
The demand reduction measures that would be implemented to address shortage levels are described in DWR
Table 8-2 (Appendix A). This table indicates which actions align with specific defined shortage levels and
estimates the extent to which that action will reduce the gap between supplies and demands. DWR Table 8-2
(Appendix A) demonstrates to the that choose suite of shortage response actions can be expected to deliver the
expected outcomes necessary to meet the requirements of a given shortage level (e.g., target of an additional
10% water savings). This table also identifies the enforcement action, if any, associated with each demand
reduction measure.
3.4.2 Supply Augmentation
The supply augmentation actions are described in DWR Table 8-3 (Appendix A). These augmentations represent
short-term management objectives triggered by the MET's WSDM Plan and do not overlap with the long-term new
water supply development or supply reliability enhancement projects. Supply Augmentation is made available to
14-47
the City through MWDOC and MET. The City relies on MET's reliability portfolio of water supply programs
including existing water transfers, storage and exchange agreements to supplement gaps in the City's
supply/demand balance. MET has developed significant storage capacity (over 5 million AF) in reservoirs and
groundwater banking programs both within and outside of the Southern California region. Additionally, MET can
pursue additional water transfer and exchange programs with other water agencies to help mitigate
supply/demand imbalances and provide additional dry -year supply sources.
MWDOC, and in turn its retail agencies, including the City, has access to supply augmentation actions through
MET. MET may exercise these actions based on regional need, and in accordance with their WSCP, and may
include the use of supplies and storage programs within the Colorado River, SWP, and in -region storage. The
City has the ability to augment its supply to reduce the shortage gap by up to 100% by purchasing additional
imported water through MWDOC or pumping additional groundwater in the OC Basin; however, both are subject
to rate penalties from MWDOC and OCWD, respectively.
3.4.3 Operational Changes
During shortage conditions, operations may be affected by supply augmentation or demand reduction responses.
The City will consider their operational procedures when it completes its Annual Assessment or as needed to
identify changes that can be implemented to address water shortage on a short-term basis, such as temporarily
altering maintenance cycles, deferring planned system outages, and adjusting the flow and routing of water
through its system to more effectively distribute available supply across the service area.
3.4.4 Additional Mandatory Restrictions
Water Code Section 10632(a)(4)(D) calls for "additional, mandatory prohibitions against specific water use
practices that are in addition to state -mandated prohibitions and appropriate to the local conditions" to be included
among the WSCP's shortage response actions. The City will identify additional mandatory restrictions as needed
based on the existing Newport Beach Municipal Code Chapter 14.16 Water Conservation and Supply Level
Regulations (Appendix B). The City intends to update any mandatory restrictions in a subsequently adopted
ordinance which will supersede the existing ordinance.
3.4.5 Emergency Response Plan (Hazard Mitigation Plan)
A catastrophic water shortage would be addressed according to the appropriate water shortage level and
response actions. It is likely that a catastrophic shortage would immediately trigger Shortage Level 6 and
response actions have been put in place to mitigate a catastrophic shortage. In addition, there are several Plans
that address catastrophic failures and align with the WSCP, including MET's WSDM and WSAP, the City's HMP,
and the Water Emergency Response Organization of Orange County (WEROC)'s Emergency Operations Plan
(EOP).
3.4.5.1 MET's WSDM and WSAP
MET has comprehensive plans for stages of actions it would undertake to address a catastrophic interruption in
water supplies through its WSDM and WSAP. MET also developed an Emergency Storage Requirement to
mitigate against potential interruption in water supplies resulting from catastrophic occurrences within the
southern California region, including seismic events along the San Andreas Fault. In addition, MET is working with
14-48
the state to implement a comprehensive improvement plan to address catastrophic occurrences outside of the
Southern California region, such as a maximum probable seismic event in the Sacramento -San Joaquin River
Delta that would cause levee failure and disruption of SWP deliveries.
3.4.5.2 Water Emergency Response Organization of Orange County Emergency
Operations Plan
In 1983, the Orange County water community identified a need to develop a plan on how agencies would respond
effectively to disasters impacting the regional water distribution system. The collective efforts of these agencies
resulted in the formation of WEROC to coordinate emergency response on behalf of all Orange County water and
wastewater agencies, develop an emergency plan to respond to disasters, and conduct disaster training
exercises for the Orange County water community. WEROC was established with the creation of an
indemnification agreement between its member agencies to protect each other against civil liabilities and to
facilitate the exchange of resources. WEROC is unique in its ability to provide a single point of contact for
representation of all water and wastewater utilities in Orange County during a disaster. This representation is to
the county, state, and federal disaster coordination agencies. Within the Orange County Operational Area,
WEROC is the recognized contact for emergency response for the water community, including the City.
As a member of WEROC, the City will follow WEROC's EOP in the event of an emergency and coordinate with
WEROC to assess damage, initiate repairs, and request and coordinate mutual aid resources in the event that the
City is unable to provide the level of emergency response support required by the situation.
The EOP defines the actions to be taken by WEROC Emergency Operations Center (EOC) staff to reduce the
loss of water and wastewater infrastructure; to respond effectively to a disaster; and to coordinate recovery
operations in the aftermath of any emergency involving extensive damage to Orange County water and
wastewater utilities. The EOP includes activation notification protocol that will be used to contact partner agencies
to inform them of the situation, activation status of the EOC, known damage or impacts, or resource needs. The
EOP is a standalone document that is reviewed annually and approved by the Board every three years.
WEROC is organized on the basis that each member agency is responsible for developing its own EOP in
accordance with the California Standardized Emergency Management System (SEMS), National Incident
Management System (NIMS), and Public Health Security and Bioterrorism Preparedness and Response Act of
2002 to meet specific emergency needs within its service area.
The WEROC EOC is responsible for assessing the overall condition and status of the Orange County regional
water distribution and wastewater collection systems including MET facilities that serve Orange County.
The EOC can be activated during an emergency situation that can result from both natural and man-made
causes, and can be activated through automatic, manual, or standby for activation.
WEROC recognized four primary phases of emergency management, which include:
• Preparedness: Planning, training, and exercises that are conducted prior to an emergency to support
and enhance response to an emergency or disaster.
• Response: Activities and programs designed to address the immediate and short-term effects of the
onset of an emergency or disaster that helps to reduce effects to water infrastructure and speed recovery.
This includes alert and notification, EOC activation, direction and control, and mutual aid.
14-49
• Recovery: This phase involved restoring systems to normal, in which short-term recovery actions are
taken to assess the damage and return vital life-support systems to minimum operating standards, while
long-term recovery actions have the potential to continue for many years.
• Mitigation/Prevention: These actions prevent the occurrence of an emergency or reduce the area's
vulnerability in ways that minimize the adverse impacts of a disaster or emergency. MWDOC's HMP
outlines threats and identifies mitigation projects.
The EOC Action Plans (EAP) provide frameworks for EOC staff to respond to different situations with the
objectives and steps required to complete them, which will in turn serve the WEROC member agencies. In the
event of an emergency which results in a catastrophic water shortage, the City will declare a water shortage
condition of up to Level 6 for the impacted area depending on the severity of the event, and coordination with
WEROC is anticipated to begin at Level 4 or greater (WEROC, 2018).
3.4.5.3 City of Newport Beach Emergency Response Plan
The City will also refer to its current American Water Infrastructure Act Risk and Resilience Assessment and
Emergency Response Plan in the event of a catastrophic supply interruption.
3.4.6 Seismic Risk Assessment and Mitigation Plan
Per the Water Code Section 10632.5, Suppliers are required to assess seismic risk to water supplies as part of
their WSCP. The plan also must include the mitigation plan for the seismic risk(s). Given the great distances that
imported supplies travel to reach Orange County, the region is vulnerable to interruptions along hundreds of miles
aqueducts, pipelines and other facilities associated with delivering the supplies to the region. Additionally, the
infrastructure in place to deliver supplies are susceptible to damage from earthquakes and other disasters.
In lieu of conducting a seismic risk assessment specific to the City's 2020 UWMP, the City has included the
previously prepared regional HMP by MWDOC, as the regional imported water wholesaler, that is required under
the federal Disaster Mitigation Act of 2000 (Public Law 106-390).
MWDOC's HMP identified that the overarching goals of the HMP were the same for all of its member agencies,
which include:
• Goal 1: Minimize vulnerabilities of critical infrastructure to minimize damages and loss of life and injury to
human life caused by hazards.
• Goal 2: Minimize security risks to water and wastewater infrastructure.
• Goal 3: Minimize interruption to water and wastewater utilities.
• Goal 4: Improve public outreach, awareness, education, and preparedness for hazards in order to
increase community resilience.
• Goal 5: Eliminate or minimize wastewater spills and overflows.
• Goal 6: Protect water quality and supply, critical aquatic resources, and habitat to ensure a safe water
supply.
• Goal 7: Strengthen Emergency Response Services to ensure preparedness, response, and recovery
during any major or multi -hazard event.
MWDOC's HMP evaluates hazards applicable to all jurisdictions in its entire planning area, prioritized based on
probability, location, maximum probable extent, and secondary impacts. The identification of hazards is highly
dependent on the location of facilities within the City's jurisdiction and takes into consideration the history of the
14-50
hazard and associated damage, information provided by agencies specializing in a specific hazard, and relies
upon the City's expertise and knowledge.
Earthquake fault rupture and seismic hazards, including ground shaking and liquefaction, are among the highest
ranked hazards to the region as a whole because of its long history of earthquakes, with some resulting in
considerable damage. A significant earthquake along one of the major faults could cause substantial casualties,
extensive damage to infrastructure, fires, damages and outages of water and wastewater facilities, and other
threats to life and property.
Nearly all of Orange County is at risk of moderate to extreme ground shaking, with liquefaction possible
throughout much of Orange County but the most extensive liquefaction zones occur in coastal areas. Based on
the amount of seismic activity that occurs within the region, there is no doubt that communities within Orange
County will continue to experience future earthquake events, and it is a reasonable assumption that a major event
will occur within a 30 -year timeframe.
The mitigation actions identify the hazard, proposed mitigation action, location/facility, local planning mechanism,
risk, cost, timeframe, possible funding sources, status, and status rationale, as applicable. For the City, mitigation
actions for seismic risks include (MWDOC, 2019):
• Update Vulnerability Assessment Plan at all utilities facilities.
• Update Risk Management Plan for Big Canyon Reservoir and 161h St Yard.
• Replacement of aging infrastructure throughout the City per the Water Master Plan.
3.4.7 Shortage Response Action Effectiveness
For each specific Shortage Response Action identified in the plan, the WSCP also estimates the extent to which
that action will reduce the gap between supplies and demands identified in DWR Table 8-2 (Appendix A). To the
extent feasible, the City has estimated percentage savings for the chosen suite of shortage response actions,
which can be anticipated to deliver the expected outcomes necessary to meet the requirements of a given
shortage level.
3.5 Communication Protocols
Timely and effective communication is a key element of the WSCP implementation. Per the Water Code Section
10632 (a)(5), the City has established communication protocols and procedures to inform customers, the public,
interested parties, and local, regional, and state governments regarding any current or predicted shortages as
determined by the Annual Assessment described pursuant to Section 10632.1; any shortage response actions
triggered or anticipated to be triggered by the Annual Assessment described pursuant to Section 10632.1; and
any other relevant communications. The City's Water Shortage Communication Protocol is documented in
Appendix C.
3.6 Compliance and Enforcement
Per Water Code Section 10632 (a)(6), the City has defined customer compliance, enforcement, appeal, and
exemption procedures for triggered shortage response actions. Procedures to ensure customer compliance are
described in Section 3.5 and customer enforcement, appeal, and exemption procedures are defined in the City's
Municipal Code Chapter 14.16 Water Conservation and Supply Level Regulations (Appendix B). The City intends
14-51
to update any enforcement procedures in a subsequently adopted ordinance which will supersede the existing
ordinance.
3.7 Legal Authorities
Per Water Code Section 10632 (a)(7)(A), the City has provided a description of the legal authorities that empower
the City to implement and enforce its shortage response in the City's Municipal Code Chapter 14.16 Water
Conservation and Supply Level Regulations (Appendix B).
Per Water Code Section 10632 (a)(7) (B), the City shall declare a water shortage emergency condition to prevail
within the area served by such wholesaler whenever it finds and determines that the ordinary demands and
requirements of water consumers cannot be satisfied without depleting the water supply of the distributor to the
extent that there would be insufficient water for human consumption, sanitation, and fire protection.
Per Water Code Section 10632 (a)(7)(C), the City shall coordinate with any agency or county within which it
provides water supply services for the possible proclamation of a local emergency under California Government
Code, California Emergency Services Act (Article 2, Section 8558). Table 3-3 identifies the contacts for all cities
or counties for which the Supplier provides service in the WSCP, along with developed coordination protocols,
can facilitate compliance with this section of the Water Code in the event of a local emergency as defined in
subpart (c) of Government Code Section 8558.
Table 3-3: Agency Contacts and Coordination Protocols
3.8 Financial Consequences of WSCP
Per Water Code Section 10632(a)(8), Suppliers must include a description of the overall anticipated financial
consequences to the Supplier of implementing the WSCP. This description must include potential reductions in
revenue and increased expenses associated with implementation of the shortage response actions. This should
be coupled with an identification of the anticipated mitigation actions needed to address these financial impacts.
During a catastrophic interruption of water supplies, prolonged drought, or water shortage of any kind, the City will
experience a reduction in revenue due to reduced water sales. Throughout this period of time, expenditures may
increase or decrease with varying circumstances. Expenditures may increase in the event of significant damage
to the water system, resulting in emergency repairs. Expenditures may also decrease as less water is pumped
through the system, resulting in lower power costs. Water shortage mitigation actions will also impact revenues
14-52
and require additional costs for drought response activities such as increased staff costs for tracking, reporting,
and communications.
The City receives water revenue from a service charge and a commodity charge based on consumption. The
service charge recovers costs associated with providing water to the serviced property. The service charge does
not vary with consumption and the commodity charge is based on water usage. Rates have been designed to
recover the full cost of water service in the charges. Therefore, the total cost of purchasing water would decrease
as the usage or sale of water decreases. In the event of a drought emergency, the City will impose excessive
water use penalties on its customers, which may include additional costs associated with reduced water revenue,
staff time taken for penalty enforcement, and advertising the excessive use penalties. The excessive water use
penalties are further described in the City's Municipal Code Chapter 14.16 Water Conservation and Supply Level
Regulations (Appendix B).
However, there are significant fixed costs associated with maintaining a minimal level of service. The City will
monitor projected revenues and expenditures should an extreme shortage and a large reduction in water sales
occur for an extended period of time. To overcome these potential revenue losses and/or expenditure impacts,
the City may use reserves. If necessary, the City may reduce expenditures by delaying implementation of its
Capital Improvement Program and equipment purchases to reallocate funds to cover the cost of operations and
critical maintenance, adjust the work force, implement a drought surcharge, and/or make adjustments to its water
rate structure.
Based on current water rates, a volumetric cutback of 50% and above of water sales may lead to a range of
reduction in revenues. The impacts to revenues will depend on a proportionate reduction in variable costs related
to supply, pumping, and treatment for the specific shortage event. The City has set aside reserve funding as a
Drought Reserve Fund to mitigate short-term water shortage situation.
3.9 Monitoring and Reporting
Per Water Code Section 10632(a)(9), the City is required to provide a description of the monitoring and reporting
requirements and procedures that have been implemented to ensure appropriate data is collected, tracked, and
analyzed for purposes of monitoring customer compliance and to meet state reporting requirements.
Monitoring and reporting key water use metrics is fundamental to water supply planning and management.
Monitoring is also essential in times of water shortage to ensure that the response actions are achieving their
intended water use reduction purposes, or if improvements or new actions need to be considered (see Section
3.10). Monitoring for customer compliance tracking is also useful in enforcement actions.
Under normal water supply conditions, potable water production figures are recorded daily. Weekly and monthly
reports are prepared and monitored. This data will be used to measure the effectiveness of any water shortage
contingency level that may be implemented. As levels of water shortage are declared by MET and MWDOC, the
City will follow implementation of those levels as appropriate based on the City's risk profile provided in UWMP
Chapter 6 and continue to monitor water demand levels. When MET calls for extraordinary conservation, MET's
Drought Program Officer will coordinate public information activities with MWDOC and monitor the effectiveness
of ongoing conservation programs.
The City will participate in monthly member agency manager meetings with both MWDOC and OCWD to monitor
and discuss monthly water allocation charts. This will enable the City to be aware of import and groundwater use
on a timely basis as a result of specific actions taken responding to the City's WSCP.
14-53
3.10 WSCP Refinement Procedures
Per Water Code Section 10632 (a)(10), the City must provide reevaluation and improvement procedures for
systematically monitoring and evaluating the functionality of the water shortage contingency plan in order to
ensure shortage risk tolerance is adequate and appropriate water shortage mitigation strategies are implemented
as needed.
The City's WSCP is prepared and implemented as an adaptive management plan. The City will use the
monitoring and reporting process defined in Section 3.9 to refine the WSCP. In addition, if certain procedural
refinements or new actions are identified by City staff, or suggested by customers or other interested parties, the
City will evaluate their effectiveness, incorporate them into the WSCP, and implement them quickly at the
appropriate water shortage level.
It is envisioned that the WSCP will be periodically re-evaluated to ensure that its shortage risk tolerance is
adequate and the shortage response actions are effective and up to date based on lessons learned from
implementing the WSCP. The WSCP will be revised and updated during the UWMP update cycle to incorporate
updated and new information. For example, new supply augmentation actions will be added, and actions that are
no longer applicable for reasons such as program expiration will be removed. However, if revisions to the WSCP
are warranted before the UWMP is updated, the WSCP will be updated outside of the UWMP update cycle. In the
course of preparing the Annual Assessment each year, City staff will routinely consider the functionality of the
overall WSCP and will prepare recommendations for the Utilities Director if changes are found to be needed.
3.11 Special Water Feature Distinction
Per Water Code Section 10632 (b), the City has defined water features in that are artificially supplied with water,
including ponds, lakes, waterfalls, and fountains, separately from swimming pools and spas, as defined in
subdivision (a) of Section 115921 of the Health and Safety Code, in the City's Municipal Code Chapter 14.16
Water Conservation and Supply Level Regulations (Appendix B).
3.12 Plan Adoption, Submittal, and Availability
Per Water Code Section 10632 (a)(c), the City provided notice of the availability of the draft 2020 UWMP and
draft 2020 WSCP and notice of the public hearing to consider adoption of the WSCP. The public review drafts of
the 2020 UWMP and the 2020 WSCP were posted prominently on City website in advance of the public hearing
on May 25, 2021. Copies of the draft WSCP were also made available for public inspection at the City Clerk's and
Utilities Department offices and public hearing notifications were published in local newspapers. A copy of the
published Notice of Public Hearing is included in Appendix D.
The City held the public hearing for the draft 2020 UWMP and draft WSCP on May 25, 2021 at the City Council
meeting. The City Council reviewed and approved the 2020 UWMP and the WSCP at its May 25, 2021 meeting
after the public hearing. See Appendix E for the resolution approving the WSCP.
By July 1, 2021, the City's adopted 2020 UWMP and WSCP was filed with DWR, California State Library, and the
County of Orange. The City will make the WSCP available for public review on its website no later than 30 days
after filing with DWR.
Based on DWR's review of the WSCP, the City will make any amendments in its adopted WSCP, as required and
directed by DWR.
14-54
If the City revises its WSCP after UWMP is approved by DWR, then an electronic copy of the revised WSCP will
be submitted to DWR within 30 days of its adoption.

The City of Newport Beach
REDUCED DELTA RELIANCE REPORTING
C.1 Background
Under the Sacramento -San Joaquin Delta Reform Act of 2009, state and local public agencies proposing a covered
action in the Delta, prior to initiating the implementation of that action, must prepare a written certification of
consistency with detailed findings as to whether the covered action is consistent with applicable Delta Plan policies
and submit that certification to the Delta Stewardship Council. Anyone may appeal a certification of consistency, and
if the Delta Stewardship Council grants the appeal, the covered action may not be implemented until the agency
proposing the covered action submits a revised certification of consistency, and either no appeal is filed, or the Delta
Stewardship Council denies the subsequent appeal.
An urban water supplier that anticipates participating in or receiving water from a proposed covered action such as
a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting
water from, or using water in the Delta should provide information in their 2015 and 2020 Urban Water Management
Plans (UWMPs) that can then be used in the covered action process to demonstrate consistency with Delta Plan
Policy WR P1, Reduce Reliance on the Delta Through Improved Regional Water Self -Reliance (WR P1).
WR P1 details what is needed for a covered action to demonstrate consistency with reduced reliance on the Delta
and improved regional self-reliance. WR P1 subsection (a) states that:
(a) Watershall not be exported from, transferred through, or used in the Delta if all of the following apply:
(1) One or more water suppliers that would receive water as a result of the export, transfer, or use have failed
to adequately contribute to reduced reliance on the Delta and improved regional self-reliance consistent with
all of the requirements listed inparagraph
(1) of subsection (c);
(2) That failure has significantly caused the need for the export, transfer, or use; and
(3) The export, transfer, or use would have a significant adverse environmental impact in the Delta.
WR P1 subsection (c)(1) further defines what adequately contributing to reduced reliance on the Delta means in terms
of (a)(1) above.
(c)(1) Watersuppliers that have done all the following are contributing to reduced reliance on the Delta and improved
regional self-reliance and are therefore consistent with this policy:
(A) Completed a current Urban or Agricultural Water Management Plan (Plan) which has been reviewed by
the California Department of Water Resources forcompliance with the applicable requirements of Water Code
Division 6, Parts 2.55, 2.6, and 2.8,
(8) Identified, evaluated, and commenced implementation, consistent with the implementation
schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost
effective and technically feasible which reduce reliance on the Delta, and
(C) Included in the Plan, commencing in 2015, the expected outcome formeasurable reduction in Delta
reliance and improvement in regional self-reliance. The expected outcome for measurable reduction in
Delta reliance and improvement in regional self- reliance shall be reported in the Plan as the reduction in
the amount of water used, or in the percentage of water used, from the Delta watershed. For the
purposes of reporting, water efficiency is considered a new source of water supply, consistent with Water
Code section 1011(a).
The analysis and documentation provided below include all of the elements described in WR P1(c)(1) that need to
be included in a water supplier's UWMP to support a certification of consistency for a future covered action.
14-59
C.2 Summary of Expected Outcomes for Reduced Reliance on the Delta
As stated in WR P1 (c)(1)(C), the policy requires that, commencing in 2015, UWMPs include expected outcomes for
measurable reduction in Delta reliance and improved regional self- reliance. WR P1 further states that those
outcomes shall be reported in the UWMP as the reduction in the amount of water used, or in the percentage of
water used, from the Delta.
The expected outcomes for the City of Newport Beach's (hereafter referred to as 'City') regional self-reliance were
developed using the approach and guidance described in Appendix C of DWR's Urban Water Management Plan
Guidebook 2020 — Final Draft (Guidebook Appendix C) issued in March 2021. The data used in this analysis represent
the total regional efforts of Metropolitan, the city, and its member agencies and were developed in conjunction with
Metropolitan as part of the UWMP coordination process.
The following provides a summary of the near-term (2025) and long-term (2045) expected outcomes for the city's
Delta reliance and regional self-reliance. The results show that as a region, the City, Metropolitan, and its member
agencies are measurably reducing reliance on the Delta and improving regional self-reliance, both as an amount of
water used and as a percentage of water used.
Expected Outcomes for Regional Self -Reliance for the City
• Near-term (2025) — Normal water year regional self-reliance is expected to increase by 8,328 AF from the
2010 baseline; this represents an increase of about 42.0 percent of 2025 normal water year retail demands
(Table C-2).
• Long-term (2040) — Normal water year regional self-reliance is expected to increase by nearly 9,016 AF from
the 2010 baseline, this represents an increase of about 44.6 percent of 2045 normal water year retail
demands (Table C-2).
C.3 Demonstration of Reduced Reliance on the Delta
The methodology used to determine the City's reduced Delta reliance and improved regional self-reliance is
consistent with the approach detailed in DWR's UWMP Guidebook Appendix C, including the use of narrative
justifications for the accounting of supplies and the documentation of specific data sources. Some of the key
assumptions underlying the City's demonstration of reduced reliance include:
• All data were obtained from the current 2020 UWMP or previously adopted UWMPs and represent
average or normal water year conditions.
• All analyses were conducted at the service area level, and all data reflect the total contributions of the
City and MWDOC, in conjunction with information provided by Metropolitan.
• No projects or programs that are described in the UWMPs as "Projects Under Development" were
included in the accounting of supplies.
Baseline and Expected Outcomes
In order to calculate the expected outcomes for measurable reduction in Delta reliance and improved regional
self-reliance, a baseline is needed to compare against. This analysis uses a normal water year representation of
2010 as the baseline, which is consistent with the approach described in the Guidebook Appendix C. Data for the
2010 baseline were taken from the city's 2005 UWMP as the UWMPs generally do not provide normal water
year data for the year that they are adopted (i.e., 2005 UWMP forecasts begin in 2010, 2010 UWMP forecasts
begin in 2015, and so on).
Consistent with the 2010 baseline data approach, the expected outcomes for reduced Delta reliance and
improved regional self-reliance for 2015 and 2020 were taken from the City's 2010 and 2015 UWMPs
respectively. Expected outcomes for 2025-2040 are from the current 2020 UWMP. Documentation of the specific
data sources and assumptions are included in the discussions below.
Service Area Demands without Water Use Efficiency
In alignment with the Guidebook Appendix C, this analysis uses normal water year demands, rather than normal
14-60
water year supplies to calculate expected outcomes in terms of the percentage of water used. Using normal
water year demands serves as a proxy for the amount of supplies that would be used in a normal water year,
which helps alleviate issues associated with howsupplycapability is presented to fulfill requirements of the UWMP
Actversus howsupplies might be accounted for to demonstrate consistency with WR P1.
Because WR P1 considers water use efficiency savings a source of water supply, water suppliers such as the City
need to explicitly calculate and report water use efficiency savings separate from service area demands to
properly reflect normal water year demands in the calculation of reduced reliance. As explained in the Guidebook
Appendix C, water use efficiency savings must be added back to the normal year demands to represent demands
without water use efficiency savings accounted for; otherwise the effect of water use efficiency savings on
regional self-reliance would be overestimated. Table C-1 shows the results of this adjustment for the City.
Supporting narratives and documentation for the all of the data shown in Table C-1 are provided below.

Service Area Demands with Water Use Efficienc
The service area demands shown in Table C-1 represent the total retail water demands for the City's service area and may
include municipal and industrial demands, agricultural demands, recycled, seawater barrier demands, and storage
replenishment demands. These demand types and the modeling methodologies used to calculate them are described in
Section 4-3 of the City's UWMP.
Non -Potable Water Demands
Any non -potable water demands shown in Table C-1 represent demands for non -potable recycled water, water used for
purposes such as surface reservoir storage, and replenishment water for groundwater basin recharge and sweater barrier
demands. Additionally, non -potable supplies have a demand hardening effect due to the inability to shift non -potable
supplies to meet potable water demands. When water use efficiency or conservation measures are implemented, they fall
solely on the potable water users. This is consistent with the approach for water conservation reporting used by the State
Water Resources Control Board.
Total Service Area Population
The City's total service area population as shown in Table C-1 come from the Center for Demographic Research, with actuals
and projections further described in Section 3.4 of the City's 2020 UWMP.
Water Use Efficiencv Since Baseline
The water use efficiency numbers shown in Table C-1 represent the formulation that City utilized, consistent with Appendix
C of the UWMP Guidebook approach.
Service area demands, excluding non -potable demands, are divided by the service area population to get per capita water
use in the service area in gallons per capita per day (GPCD) for each five-year period. The change in per capita water use
from the baseline is the comparative GPCD from that five-year period compared to the 2010 baseline. Changes in per capita
water use over time are then applied back to the City's service area population to calculate the estimated WUE Supply. This
estimated WUE Supply is considered an additional supply that may be used to show reduced reliance on Delta water
supplies.
The demand and water use efficiency data shown in Table C-1 were collected from the following sources:
• Baseline (2010) values — City's 2005 UWMP
• 2015 values — City's 2010 UWMP
• 2020 values — City's 2015 UWMP
• 2025-2040 values — City's 2020 UWMP
It should be noted that the results of this calculation differ from what the City calculated under section 5.2 pertaining to
the Water Conservation Act of 2009 (SB X7-7) due to differing formulas.
CA Supplies Contributing to Regional Self -Reliance
For a covered action to demonstrate consistency with the Delta Plan, WR P1 subsection (c)(1)(C) states that water suppliers
must report the expected outcomes for measurable improvement in regional self-reliance. Table C-2 shows expected
outcomes for supplies contributing to regional self-reliance both in amount and as a percentage. The numbers shown in
Table C-2 represent efforts to improve regional self-reliance for the City's entire service area and include the total
contributions of the City. Supporting narratives and documentation for the all of the data shown in Table C-2 are provided
below.
The results shown in Table C-2 demonstrate that the City's service area is measurably improving its regional self-
reliance. In the near-term (2025), the expected outcome for normal water year regional self-reliance increases by
8,328 AF from the 2010 baseline; this represents an increase of about 42.0 percent of 2025 normal water year retail
demands. In the long-term (2040), normal water year regional self-reliance is expected to increase by more than
9,016 AF from the 2010 baseline; this represents an increase of about 44.6 percent of 2040 normal water year retail
demands.

C.5 Reliance on Water Supplies from the Delta Watershed
Metropolitan's service area as a whole, reduces reliance on the Delta through investments in non -Delta water supplies,
local water supplies and demand management measures. Quantifying the City's investments in self-reliance, locally,
regionally, and throughout Southern California is infeasible for the reasons as noted in Section C.6. Due to the regional
nature of these investments, the City is relying on Metropolitan's regional accounting of measurable reductions in supplies
from the Delta Watershed.
The results shown in Table A.11-3 demonstrate that Metropolitan's service area, including the City, is measurably reducing
its Delta reliance. In the near-term (2025), the expected outcome for normal water year reliance on supplies from the
Delta watershed decreased by 301 TAF from the 2010 baseline; this represents a decrease of 3 percent of 2025 normal
water year retail demands. In the long- term (2045), normal water year reliance on supplies from the Delta watershed
decreased by 314 TAF from the 2010 baseline; this represents a decrease of just over 5 percent of 2045 normal water year
retail demands.

C.6 Infeasibility of Accounting Supplies from the Delta Watershed for Metropolitan's
Member Agencies and their Customers
Metropolitan's service area, as a whole, reduces reliance on the Delta through investments in non -Delta water
supplies, local water supplies, and regional and local demand management measures. Metropolitan's member
agencies coordinate reliance on the Delta through their membership in Metropolitan, a regional cooperative
providing wholesale water service to its 26 member agencies. Accordingly, regional reliance on the Delta can only be
measured regionally—not by individual Metropolitan member agencies and not by the customers of those member
agencies.
Metropolitan's member agencies, and those agencies' customers, indirectly reduce reliance on the Delta through
their collective efforts as a cooperative. Metropolitan's member agencies do not control the amount of Delta water
they receive from Metropolitan. Metropolitan manages a statewide integrated conveyance system consisting of its
participation in the State Water Project (SWP), its Colorado River Aqueduct (CRA) including Colorado River water
resources, programs and water exchanges, and its regional storage portfolio. Along with the SWP, CRA, storage
programs, and Metropolitan's conveyance and distribution facilities, demand management programs increase the

C.6 Infeasibility of Accounting Supplies from the Delta Watershed for Metropolitan's
Member Agencies and their Customers
Metropolitan's service area, as a whole, reduces reliance on the Delta through investments in non -Delta water
supplies, local water supplies, and regional and local demand management measures. Metropolitan's member
agencies coordinate reliance on the Delta through their membership in Metropolitan, a regional cooperative
providing wholesale water service to its 26 member agencies. Accordingly, regional reliance on the Delta can only be
measured regionally—not by individual Metropolitan member agencies and not by the customers of those member
agencies.
Metropolitan's member agencies, and those agencies' customers, indirectly reduce reliance on the Delta through
their collective efforts as a cooperative. Metropolitan's member agencies do not control the amount of Delta water
they receive from Metropolitan. Metropolitan manages a statewide integrated conveyance system consisting of its
participation in the State Water Project (SWP), its Colorado River Aqueduct (CRA) including Colorado River water
resources, programs and water exchanges, and its regional storage portfolio. Along with the SWP, CRA, storage
programs, and Metropolitan's conveyance and distribution facilities, demand management programs increase the
14-64
future reliability of water resources for the region. In addition, demand management programs provide system -wide
benefits by decreasing the demand for imported water, which helps to decrease the burden on the district's
infrastructure and reduce system costs, and free up conveyance capacity to the benefit of all member agencies.
Metropolitan's costs are funded almost entirely from its service area, with the exception of grants and other
assistance from government programs. Most of Metropolitan's revenues are collected directly from its member
agencies. Properties within Metropolitan's service area pay a property tax that currently provides approximately 8
percent of the fiscal year 2021 annual budgeted revenues. The rest of Metropolitan's costs are funded through rates
and charges paid by Metropolitan's member agencies for the wholesale services it provides to them.' Thus,
Metropolitan's member agencies fund nearly all operations Metropolitan undertakes to reduce reliance on the Delta,
including Colorado River Programs, storage facilities, Local Resources Programs and Conservation Programs within
Metropolitan's service area.
Because of the integrated nature of Metropolitan's systems and operations, and the collective nature of
Metropolitan's regional efforts, it is infeasible to quantify each of Metropolitan member agencies' individual reliance
on the Delta. It is infeasible to attempt to segregate an entity and a system that were designed to work as an
integrated regional cooperative.
In addition to the member agencies funding Metropolitan's regional efforts, they also invest in their own local
programs to reduce their reliance on any imported water. Moreover, the customers of those member agencies may
also invest in their own local programs to reduce water demand. However, to the extent those efforts result in
reduction of demands on Metropolitan, that reduction does not equate to a like reduction of reliance on the Delta.
Demands on Metropolitan are not commensurate with demands on the Delta because most of Metropolitan member
agencies receive blended resources from Metropolitan as determined by Metropolitan—not the individual member
agency—and for most member agencies, the blend varies from month-to-month and year-to-year due to hydrology,
operational constraints, use of storage and other factors.
Colorado River Programs
As a regional cooperative of member agencies, Metropolitan invests in programs to ensure the continued reliability
and sustainability of Colorado River supplies. Metropolitan was established to obtain an allotment of Colorado River
water, and its first mission was to construct and operate the CRA. The CRA consists of five pumping plants, 450 miles
of high voltage power lines, one electric substation, four regulating reservoirs, and 242 miles of aqueducts, siphons,
canals, conduits and pipelines terminating at Lake Mathews in Riverside County. Metropolitan owns, operates, and
manages the CRA. Metropolitan is responsible for operating, maintaining, rehabilitating, and repairing the CRA, and
is responsible for obtaining and scheduling energy resources adequate to power pumps at the CRA's five pumping
stations.
Colorado River supplies include Metropolitan's basic Colorado River apportionment, along with supplies that result
from existing and committed programs, including supplies from the Imperial Irrigation District (IID) -Metropolitan
Conservation Program, the implementation of the Quantification Settlement Agreement (QSA) and related
agreements, and the exchange agreement with San Diego County Water Authority (SDCWA). The QSA established
the baseline water use for each of the agreement parties and facilitates the transfer of water from agricultural
agencies to urban uses. Since the QSA, additional programs have been implemented to increase Metropolitan's CRA
supplies. These include the PVID Land Management, Crop Rotation, and Water Supply Program, as well as the Lower
Colorado River Water Supply Project. The 2007 Interim Guidelines provided for the coordinated operation of Lake
Powell and Lake Mead, as well as the Intentionally Created Surplus (ICS) program that allows Metropolitan to store
water in Lake Mead.
Storage Investments/Facilities
Surface and groundwater storage are critical elements of Southern California's water resources strategy and help
Metropolitan reduce its reliance on the Delta. Because California experiences dramatic swings in weather and
' A standby charge is collected from properties within the service areas of 21 of Metropolitan's 26 member agencies, ranging from
$5 to $14.20 per acre annually, or per parcel if smaller than an acre. Standby charges go towards those member agencies'
obligations to Metropolitan for the Readiness -to -Serve Charge. The total amount collected annually is approximately $43.8 million,
approximately 2 percent of Metropolitan's fiscal year 2021 annual budgeted revenues.
14-65
hydrology, storage is important to regulate those swings and mitigate possible supply shortages. Surface and
groundwater storage provide a means of storing water during normal and wet years for later use during dry years,
when imported supplies are limited. The Metropolitan system, for purposes of meeting demands during times of
shortage, regulating system flows, and ensuring system reliability in the event of a system outage, provides over
1,000,000 acre-feet of system storage capacity. Diamond Valley Lake provides 810,000 acre-feet of that storage
capacity, effectively doubling Southern California's previous surface water storage capacity. Other existing imported
water storage available to the region consists of Metropolitan's raw water reservoirs, a share of the SWP's raw water
reservoirs in and near the service area, and the portion of the groundwater basins used for conjunctive -use storage.
Since the early twentieth century, DWR and Metropolitan have constructed surface water reservoirs to meet
emergency, drought/seasonal, and regulatory water needs for Southern California. These reservoirs include Pyramid
Lake, Castaic Lake, Elderberry Forebay, Silverwood Lake, Lake Perris, Lake Skinner, Lake Mathews, Live Oak Reservoir,
Garvey Reservoir, Palos Verdes Reservoir, Orange County Reservoir, and Metropolitan's Diamond Valley Lake (DVL).
Some reservoirs such as Live Oak Reservoir, Garvey Reservoir, Palos Verdes Reservoir, and Orange County Reservoir,
which have a total combined capacity of about 3,500 AF, are used solely for regulating purposes. The total gross
storage capacity for the larger remaining reservoirs is 1,757,600 AF. However, not all of the gross storage capacity is
available to Metropolitan; dead storage and storage allocated to others reduce the amount of storage that is
available to Metropolitan to 1,665,200 AF.
Conjunctive use of the aquifers offers another important source of dry year supplies. Unused storage in Southern
California groundwater basins can be used to optimize imported water supplies, and the development of
groundwater storage projects allows effective management and regulation of the region's major imported supplies
from the Colorado River and SWP. Over the years, Metropolitan has implemented conjunctive use through various
programs in the service area; the following table lists the groundwater conjunctive use programs that have been
developed in the region.

Metropolitan Demand Management Programs
Demand management costs are Metropolitan's expenditures for funding local water resource development
programs and water conservation programs. These Demand Management Programs incentivize the development of
local water supplies and the conservation of water to reduce the need to import water to deliver to Metropolitan's
member agencies. These programs are implemented below the delivery points between Metropolitan's and its
member agencies' distribution systems and, as such, do not add any water to Metropolitan's supplies. Rather, the
effect of these downstream programs is to produce a local supply of water for the local agencies and to reduce
demands by member agencies for water imported through Metropolitan's system. The following discussions outline
how Metropolitan funds local resources and conservation programs for the benefit of all of its member agencies and
the entire Metropolitan service area. Notably, the history of demand management by Metropolitan's member
agencies and the local agencies that purchase water from Metropolitan's members has spanned more than four
decades. The significant history of the programs is another reason it would be difficult to attempt to assign a portion
of such funding to any one individual member agency.
Local Resources Programs
In 1982, Metropolitan began providing financial incentives to its member agencies to develop new local supplies to
assist in meeting the region's water needs. Because of Metropolitan's regional distribution system, these programs
benefit all member agencies regardless of project location because they help to increase regional water supply
reliability, reduce demands for imported water supplies, decrease the burden on Metropolitan's infrastructure,
reduce system costs and free up conveyance capacity to the benefit of all the agencies that rely on water from
Metropolitan.
For example, the Groundwater Replenishment System (GWRS) operated by the Orange County Water District is the
14-67
world's largest water purification system for indirect potable reuse. It was funded, in part, by Metropolitan's member
agencies through the Local Resources Program. Annually, the GWRS produces approximately 103,000 acre-feet of
reliable, locally controlled, drought -proof supply of high-quality water to recharge the Orange County Groundwater
Basin and protect it from seawater intrusion. The GWRS is a premier example of a regional project that significantly
reduced the need to utilize imported water for groundwater replenishment in Metropolitan's service area, increasing
regional and local supply reliability and reducing the region's reliance on imported supplies, including supplies from
the State Water Project.
Metropolitan's local resource programs have evolved through the years to better assist Metropolitan's member
agencies in increasing local supply production. The following is a description and history of the local supply incentive
programs.
Local Projects Program
In 1982, Metropolitan initiated the Local Projects Program (LPP), which provided funding to member agencies to
facilitate the development of recycled water projects. Under this approach, Metropolitan contributed a negotiated
up -front funding amount to help finance project capital costs. Participating member agencies were obligated to
reimburse Metropolitan over time. In 1986, the LPP was revised, changing the up -front funding approach to an
incentive -based approach. Metropolitan contributed an amount equal to the avoided State Water Project pumping
costs for each acre-foot of recycled water delivered to end-use consumers. This funding incentive was based on the
premise that local projects resulted in the reduction of water imported from the Delta and the associated pumping
cost. The incentive amount varied from year to year depending on the actual variable power cost paid for State Water
Project imports. In 1990, Metropolitan's Board increased the LPP contribution to a fixed rate of $154 per acre-foot,
which was calculated based on Metropolitan's avoided capital and operational costs to convey, treat, and distribute
water, and included considerations of reliability and service area demands.
Groundwater Recovery Program
The drought of the early 1990s sparked the need to develop additional local water resources, aside from recycled
water, to meet regional demand and increase regional water supply reliability. In 1991, Metropolitan conducted the
Brackish Groundwater Reclamation Study which determined that large amounts of degraded groundwater in the
region were not being utilized. Subsequently, the Groundwater Recovery Program (GRP) was established to assist
the recovery of otherwise unusable groundwater degraded by minerals and other contaminants, provide access to
the storage assets of the degraded groundwater, and maintain the quality of groundwater resources by reducing the
spread of degraded plumes.
Local Resources Program
In 1995, Metropolitan's Board adopted the Local Resources Program (LRP), which combined the LPP and GRP into
one program. The Board allowed for existing LPP agreements with a fixed incentive rate to convert to the sliding
scale up to $250 per acre-foot, similar to GRP incentive terms. Those agreements that were converted to LRP are
known as "LRP Conversions."
Competitive Local Projects Program
In 1998, the Competitive Local Resources Program (Competitive Program) was established. The Competitive Program
encouraged the development of recycled water and recovered groundwater through a process that emphasized cost -
efficiency to Metropolitan, timing new production according to regional need while minimizing program
administration cost. Under the Competitive Program, agencies requested an incentive rate up to $250 per acre-foot
of production over 25 years under a Request for Proposals (RFP) for the development of up to 53,000 acre-feet per
year of new water recycling and groundwater recovery projects. In 2003, a second RFP was issued for the
development of an additional 65,000 acre-feet of new recycled water and recovered groundwater projects through
the LRP.
Seawater Desalination Program
Metropolitan established the Seawater Desalination Program (SDP) in 2001 to provide financial incentives to member
agencies for the development of seawater desalination projects. In 2014, seawater desalination projects became
eligible for funding under the LRP, and the SDP was ended.
14-68
2007 Local Resources Program
In 2006, a task force comprised of member agency representatives was formed to identify and recommend program
improvements to the LRP. As a result of the task force process, the 2007 LRP was established with a goal of 174,000
acre-feet per year of additional local water resource development. The new program allowed for an open application
process and eliminated the previous competitive process. This program offered sliding scale incentives of up to $250
per acre-foot, calculated annually based on a member agency's actual local resource project costs exceeding
Metropolitan's prevailing water rate.
2014 Local Resources Program
A series of workgroup meetings with member agencies was held to identify the reasons why there was a lack of new
LRP applications coming into the program. The main constraint identified by the member agencies was that the $250
per acre-foot was not providing enough of an incentive for developing new projects due to higher construction costs
to meet water quality requirements and to develop the infrastructure to reach end-use consumers located further
from treatment plants. As a result, in 2014, the Board authorized an increase in the maximum incentive amount,
provided alternative payment structures, included onsite retrofit costs and reimbursable services as part of the LRP,
and added eligibility for seawater desalination projects. The current LRP incentive payment options are structured
as follows:
• Option 1— Sliding scale incentive up to $340/AF for a 25 -year agreement term
• Option 2 — Sliding scale incentive up to $475/AF for a 15 -year agreement term
• Option 3 — Fixed incentive up to $305/AF for a 25 -year agreement term
On-site Retrofit Programs
In 2014, Metropolitan's Board also approved the On-site Retrofit Pilot Program which provided financial incentives
to public or private entities toward the cost of small-scale improvements to their existing irrigation and industrial
systems to allow connection to existing recycled water pipelines. The On-site Retrofit Pilot Program helped reduce
recycled water retrofit costs to the end-use consumer which is a key constraint that limited recycled water LRP
projects from reaching full production capacity. The program incentive was equal to the actual eligible costs of the
on-site retrofit, or $975 per acre-foot of up -front cost, which equates to $195 per acre-foot for an estimated five
years of water savings ($195/AF x 5 years) multiplied by the average annual water use in previous three years,
whichever is less. The Pilot Program lasted two years and was successful in meeting its goal of accelerating the use
of recycled water.
In 2016, Metropolitan's Board authorized the On-site Retrofit Program (ORP), with an additional budget of $10
million. This program encompassed lessons learned from the Pilot Program and feedback from member agencies to
make the program more streamlined and improve its efficiency. As of fiscal year 2019/20, the ORP has successfully
converted 440 sites, increasing the use of recycled water by 12,691 acre-feet per year.
Storm water Pilot Programs
In 2019, Metropolitan's Board authorized both the Stormwater for Direct Use Pilot Program and a Stormwater for
Recharge Pilot Program to study the feasibility of reusing stormwater to help meet regional demands in Southern
California. These pilot programs are intended to encourage the development, monitoring, and study of new and
existing stormwater projects by providing financial incentives for their construction/retrofit and
monitoring/reporting costs. These pilot programs will help evaluate the potential benefits delivered by stormwater
capture projects and provide a basis for potential future funding approaches. Metropolitan's Board authorized a total
of $12.5 million for the stormwater pilot programs ($5 million for the District Use Pilot and $7.5 million for the
Recharge Pilot).
Current Status and Results of Metropolitan's Local Resource Programs
Today, nearly one-half of the total recycled water and groundwater recovery production in the region has been
developed with an incentive from one or more of Metropolitan's local resource programs. During fiscal year 2020,
Metropolitan provided about $13 million for production of 71,000 acre-feet of recycled water for non -potable and
indirect potable uses. Metropolitan provided about $4 million to support projects that produced about 50,000 acre -
14 -69
feet of recovered groundwater for municipal use. Since 1982, Metropolitan has invested $680 million to fund 85
recycled water projects and 27 groundwater recovery projects that have produced a cumulative total of about 4
million acre-feet.
Conservation Programs
Metropolitan's regional conservation programs and approaches have a long history. Decades ago, Metropolitan
recognized that demand management at the consumer level would be an important part of balancing regional
supplies and demands. Water conservation efforts were seen as a way to reduce the need for imported supplies and
offset the need to transport or store additional water into or within the Metropolitan service area. The actual
conservation of water takes place at the retail consumer level. Regional conservation approaches have proven to be
effective at reaching retail consumers throughout Metropolitan's service area and successfully implementing water
saving devices, programs and practices. Through the pooling of funding by Metropolitan's member agencies,
Metropolitan is able to engage in regional campaigns with wide -reaching impact. Regional investments in demand
management programs, of which conservation is a key part along with local supply programs, benefit all member
agencies regardless of project location. These programs help to increase regional water supply reliability, reduce
demands for imported water supplies, decrease the burden on Metropolitan's infrastructure, reduce system costs,
and free up conveyance capacity to the benefit of all member agencies.
Incentive -Based Conservation Programs
Conservation Credits Program
In 1988, Metropolitan's Board approved the Water Conservation Credits Program (Credits Program). The Credits
Program is similar in concept to the Local Projects Program (LPP). The purpose of the Credits Program is to encourage
local water agencies to implement effective water conservation projects through the use of financial incentives. The
Credits Program provides financial assistance for water conservation projects that reduce demands on
Metropolitan's imported water supplies and require Metropolitan's assistance to be financially feasible.
Initially, the Credits Program provided 50 percent of a member agency's program cost, up to a maximum of $75 per
acre-foot of estimated water savings. The $75 Base Conservation Rate was established based Metropolitan's avoided
cost of pumping SWP supplies. The Base Conservation Rate has been revisited by Metropolitan's Board and revised
twice since 1988, from $75 to $154 per acre-foot in 1990 and from $154 to $195 per acre-foot in 2005.
In fiscal year 2020 Metropolitan processed more than 30,400 rebate applications totaling $18.9 million.
Member Agency Administered Program
Some member agencies also have unique programs within their service areas that provide local rebates that may
differ from Metropolitan's regional program. Metropolitan continues to support these local efforts through a
member agency administered funding program that adheres to the same funding guidelines as the Credits Program.
The Member Agency Administered Program allows member agencies to receive funding for local conservation efforts
that supplement, but do not duplicate, the rebates offered through Metropolitan's regional rebate program.
Water Savings Incentive Program
There are numerous commercial entities and industries within Metropolitan's service area that pursue unique
savings opportunities that do not fall within the general rebate programs that Metropolitan provides. In 2012,
Metropolitan designed the Water Savings Incentive Program (WSIP) to target these unique commercial and industrial
projects. In addition to rebates for devices, under this program, Metropolitan provides financial incentives to
businesses and industries that created their own custom water efficiency projects. Qualifying custom projects can
receive funding for permanent water efficiency changes that result in reduced potable demand.
Non -Incentive Conservation Programs
In addition to its incentive -based conservation programs, Metropolitan also undertakes additional efforts throughout
its service area that help achieve water savings without the use of rebates. Metropolitan's non -incentive
conservation efforts include:
• residential and professional water efficient landscape training classes
14-70
• water audits for large landscapes
• research, development and studies of new water saving technologies
• advertising and outreach campaigns
• community outreach and education programs
• advocacy for legislation, codes, and standards that lead to increased water savings
Current Status and Results of Metropolitan's Conservation Programs
Since 1990, Metropolitan has invested $824 million in conservation rebates that have resulted in a cumulative savings
of 3.27 million acre-feet of water. These investments include $450 million in turf removal and other rebates during
the last drought which resulted in 175 million square feet of lawn turf removed. During fiscal year 2020, 1.06 million
acre-feet of water is estimated to have been conserved. This annual total includes Metropolitan's Conservation
Credits Program; code -based conservation achieved through Metropolitan -sponsored legislation; building plumbing
codes and ordinances; reduced consumption resulting from changes in water pricing; and pre -1990 device retrofits.
Infeasibility of Accounting Regional Investments in Reduced Reliance Below the Regional Level
The accounting of regional investments that contribute to reduced reliance on supplies from the Delta watershed is
straightforward to calculate and report at the regional aggregate level. However, any similar accounting is infeasible
forthe individual member agencies ortheir customers. As described above, the region (through Metropolitan) makes
significant investments in projects, programs and other resources that reduce reliance on the Delta. In fact, all of
Metropolitan's investments in Colorado River supplies, groundwater and surface storage, local resources
development and demand management measures that reduce reliance on the Delta are collectively funded by
revenues generated from the member agencies through rates and charges.
Metropolitan's revenues cannot be matched to the demands or supply production history of an individual agency,
or consistently across the agencies within the service area. Each project or program funded by the region has a
different online date, useful life, incentive rate and structure, and production schedule. It is infeasible to account for
all these things over the life of each project or program and provide a nexus to each member agency's contributions
to Metropolitan's revenue stream over time. Accounting at the regional level allows for the incorporation of the local
supplies and water use efficiency programs done by member agencies and their customers through both the regional
programs and through their own specific local programs. As shown above, despite the infeasibility of accounting
reduced Delta reliance below the regional level, Metropolitan's member agencies and their customers have together
made substantial contributions to the region's reduced reliance.
