REQUEST FOR CITY COUNCIL ACTION
SUBMITTED TO: Honorable Mayor and City Council Members
SUBMITTED BY: Oliver Chi, City Manager
PREPARED BY: Sean Crumby, Director of Public Works
Subject:
Adopt Ordinance No. 4233 amending Chapter 14.18 of the Huntington Beach Municipal Code
Water Management Program
Approved for introduction June 1, 2021 - Vote: 6-0-1 (Ortiz absent)
Statement of Issue:
Ordinance No. 4233 approved for introduction on June 1 , 2021 requires adoption.
Financial Impact:
Not applicable.
Recommended Action:
Adopt Ordinance No. 4233, "An Ordinance of the City of Huntington Beach Amending Chapter 14.18
of the Huntington Beach Municipal Code Water Management Program."
Alternative Action(s):
Do not approve the plan(s) and/or ordinance in part, or as a whole, and direct staff accordingly.
Analysis:
The Urban Water Management Planning Act of 1983 requires water suppliers with more than 3,000
customers or supplying more than 3,000 acre-feet (AF) of water annually to prepare and adopt an
Urban Water Management Plan (UWMP) every five (5) years.
UWMPs are comprehensive documents that present an evaluation of a water supplier's reliability
over a long-term horizon, typically 20-25 years. The City supplies water to approximately 200,000
residents, over 53,000-metered connections, and around 26,000 AF of water annually. The City last
updated the UWMP on June 20, 2016. and must adopt and submit an updated UWMP to the
Department of Water Resources (DWR) by July 1, 2021.

File #: 21-447 MEETING DATE: 6/15/2021
For this 2020 UWMP cycle, DWR placed emphasis on achieving improvements for long-term
reliability and resilience to drought and climate change in California. The 2020 UWMP updates
various 2015 UWMP items related to water resource needs, water use efficiency, assessment of
water reliability, and strategies to mitigate water shortage conditions. The 2020 UWMP includes a
2020 Water Shortage Contingency Plan (WSCP), which is a strategic planning document designed to
prepare the City to effectively respond to water shortages, and is required for compliance with Water
Code Section 10632.
The WSCP requires the City to amend Huntington Beach Municipal Code Chapter 14.18 Water
Management Program to match the new requirement to plan for six (6) levels of water shortage, and
to take appropriate demand-reduction measures at each shortage level, as outlined in the WSCP.
The 2020 UWMP and 2020 WSCP were prepared in coordination with MWDOC, the Metropolitan
Water District of Southern California (MET), and the Orange County Water District (OCWD).
The 2020 UWMP includes a Drought Risk Assessment (DRA), which evaluates the City's near-term
ability to supply water during drought conditions. Water demand is projected to increase 1 .7% over
the next five years; however, in the longer term, water demand is projected to decrease 1.3% from
2025 through 2045. The projected potable water use for 2045 is 26.054 AF. Even under the
assumption of a drought over the next five (5) 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 water supply gap.
As part of the 2020 UWMP Public Hearing and Adoption action, an addendum to the 2015 UWMP
adding Appendix L to the 2015 plan to ensure compliance with the Delta Plan Policy WR P1 is
included for consideration. Appendix L was not included in DWR guidance for the 2015 UWMPs at
the time and was, therefore, not included in MET's, MWDOC's, or the City of Huntington Beach's
UWMP. Appendix L is not a requirement of the California Water Code related to Urban Water
Management Planning; however, it is important for the City to include the appendix in both its 2020
UWMP and its 2015 UWMP for MET to certify that the Delta Conveyance Project is consistent with
the Delta Stewardship Council policies. The proposed project allows for the modernization of the
State Water Project system, through which the City receives imported water supplies from MWDOC.

EXECUTIVE SUMMARY
INTRODUCTION AND UWMP OVERVIEW
The City of Huntington Beach prepared this 2020 Urban Water Management Plan (UWMP) 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 customers using a
combination of local groundwater from the Orange County Groundwater Basin (OC Basin) and
supplemental imported potable water supply obtained from its regional wholesaler, Municipal Water
District of Orange County (MWDOC).
UWMPs are comprehensive documents that present an evaluation of a water supplier's reliability over a
long-term horizon, typically 20-25 years. This 2020 UWMP provides an assessment of the present and
future water supply sources and demands within the City's service area. It updates various 2015 UWMP
items related to: water resource needs, water use efficiency, assessment of water reliability, and
strategies to mitigate water shortage conditions. The 2020 UWMP adds a 2020 Water Shortage
Contingency Plan (WSCP) to help the City effectively respond to potential water shortages. This 2020
UWMP contains all elements needed to comply with 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 wholesale supplier for Orange County), MET (regional wholesaler for Southern California and
the direct supplier of imported water to MWDOC), and OCWD (OC Basin manager). 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 in 1909 and is governed by a seven-member elected City Council. In 1964, the
City's Water Division was established as a Division of the Public Works Department. In 2003, the Public
Works Wastewater Section was incorporated into the Water Division to form the Utilities Division.
The City's water service area covers 27.3 square miles, along the Southern California Coast of Orange
County, located 35 miles southeast of Los Angeles and 90 miles northwest of San Diego. The City's
Public Works Department operates four storage and distribution reservoirs with a combined capacity of
55 million gallons (MG), four booster stations, eight active groundwater wells and manages 607.2-mile
water main system with 55,028 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 mostly developed and is a predominantly single and multi-family residential community. Moving
forward, new development will occur as a result of market response to changing conditions such as
population growth, demographics, and the economy as well as the need to replace aging buildings and
improve homes. The City will continue planning for its Regional Housing Needs Assessment (RHNA)

Huntington Beach 2020 Urban Water Management Plan
allocation and future planned developments may potentially include accessory dwelling units (ADUs). The
current population of 201,327 is projected to increase by 2.3% 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 27,753 AF for potable use. In FY 2019-20, the City's water use was 25,966 AF of potable
water(groundwater and imported).
In FY 2019-20, 18,206 AF (or 70%) of the City's potable water demand was residential, with commercial,
industrial, institutional/governmental, dedicated landscape, and losses accounting for the remaining 30%
of the total potable water demand. More specifically, commercial water use accounted for 3,240 AF (or
12.5%) of total water demand and dedicated landscape for 2,141 AF (or 8.2%) of total water demand.
Industrial and institutional/governmental uses make up about 741 AF (2.9%) of total demand. Non-
revenue water comprised 6.3% of total water demand.
WATER USE PROJECTIONS: 5-YEAR AND 25-YEAR
Water use within the City's service area has been relatively stable in the past decade and is expected to
remain stable as the city is essentially built-out and the rate of population growth is expected to average
less than 0.1% per year for the next 25 years.
Water demand is projected to increase 1.7% over the next five years. In the longer term, water demand is
projected to decrease 1.3% from 2025 through 2045. The projected potable water use for 2045 is 26,054
AF.
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 IvIWDOC, 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 88 gallons per capita per day (GPCD), which is below its 2020 target of 142 GPCD.
WATER SUPPLY CHARACTERIZATION
The City meets its demands through a combination of local groundwater and supplemental imported
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
arcades com
ES-2
897
Huntington Beach 2020 Urban Water Management Plan
sources of imported water supplies include water from the Colorado River and the State Water Project
(SWP) provided by MET and delivered through MWDOC.
In FY 2019-20, the City's water supplies consisted of 70% groundwater and 30% imported water.
It is projected that by 2045, the water supply mix will shift to 85% groundwater and 15% imported 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 Orange County Sanitation District (OC
San) for treatment and disposal. OCWD's Groundwater Replenishment System (GWRS) produces
recycled water for indirect potable reuse (IPR) through the replenishment of the OC Basin. The City
benefits from this indirect use of recycled water.
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 UWMP 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 the same 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 indirect recycled water.
WATER SHORTAGE CONTINGENCY PLANNING
Water shortage contingency planning (WSCP) is a strategic planning process that the City engages in 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, 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
arcadis.com

898
Huntington Beach 2020 Urban Water Management Plan
governing body, its staff, and its retail agencies can easily identify and efficiently implement
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 in Orange County, recognizes the need to use existing
water supplies efficiently, This ethic of efficient use of water has evolved as a result of the development
and implementation of water use efficiency programs that make good economic sense and reflect
responsible stewardship of the region's water resources. The City participates in regional water savings
programs and works closely with MET and MWDOC to promote regional efficiency.
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 other key agencies and made the document available for
public review no later than 30 days after fling with DWR.

Huntington Beach 2020 Urban Water Management Plan
1 INTRODUCTION AND UWMP OVERVIEW
The City of Huntington Beach (City) prepared this 2020 Urban Water Management Plan (UWMP or Plan)
to satisfy the UWMP Act of 1983 (Act or UWMP Act) and subsequent California Water Code (Water
Code) requirements. The City is a retail water supplier that provides water to its residents and customers
using a combination of imported potable water supply obtained from its regional wholesaler, Municipal
Water District of Orange County (MWDOC) and local groundwater from the Orange County Groundwater
Basin (OC Basin). The City is a member agency of both MWDOC (28 members) and Orange County
Water District ((OCWD) (19 members)). The City prepared this 2020 UWMP in collaboration with
MWDOC, OCWD, the Metropolitan Water District of Southern California (MET), and other key agencies.
UWMPs are comprehensive documents that present an evaluation of a water supplier's reliability over a
long-term horizon, typically 20-25 years. In response to changing climate conditions and regulatory
updates since the 2015 UWMP, the City has been proactively managing its water supply and demand.
The water loss audit program, water conservation measures and efforts for increased self-reliance in
order to reduce dependency on imported water from the Sacramento-San Joaquin Delta (the Delta) are
some of the water management efforts that the City is a part of to maintain the reliability of water supply
for its service area.
This 2020 UWMP provides an assessment of the present and future water supply sources and demands
within the City's service area. It updates various 2015 UWMP items related to: water resource needs,
water use efficiency, assessment of water reliability, and strategies to mitigate water shortage conditions.
The 2020 UWMP adds a 2020 Water Shortage Contingency Plan (WSCP) to help the City effectively
respond to potential water shortages. This 2020 UWMP contains all elements needed to comply with new
requirements of the Act as amended since 2015.
1 .1 Overview of Urban Water Management Plan Requirements
The UWMP Act requires every urban water supplier (Supplier) providing water for municipal purposes to
more than 3,000 customers or supplying more than 3,000 acre-feet (AF) of water annually, to prepare,
adopt, and file an UWMP with the DWR every five (5) years for each year ending in "0" and "5".
For this 2020 UWMP cycle, DWR placed emphasis on achieving improvements for long-term reliability
and resilience to drought and climate change in California. Legislation related to water supply planning in
California has evolved to address these issues, namely Making Conservation a Way of Life [Assembly Bill
(AB) 1668 and Senate Bill (SB) 606] and Water Loss Performance Standard SB555. New UWMP
requirements in 2020 are a direct result of these new water regulations.
The 2020 UWMP added two (2)components complimenting the legislation mentioned above. First is the
WSCP, which assesses the Supplier's near-term, five-year drought risk assessment (DRA) and provides
a structured guide to deal with water shortages. Second is the Annual Water Supply Demand
Assessment (WSDA), which assesses the current year plus one dry year i.e., short-term demand/supply
outlook. Analyses over near- and long-term horizons together provide a more complete picture of a
Supplier's reliability and serve to inform appropriate actions needed to build up capacity over the long
term.

Huntington Beach 2020 Urban Water Management Plan
Key additions to the 2020 UWMP in accordance with recent water regulations are:
• Water Shortage Contingency Plan (WSCP) —WSCP helps a Supplier to better prepare for
drought conditions and provides the steps and water use efficiency measures to be taken in times
of water shortage conditions. WSCP now has more prescriptive elements, including an analysis
of water supply reliability; the water use efficiency measures for each of the six standard water
shortage levels, that correspond to water shortage percentages ranging from 0-10% 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 water supply and demand assessment; monitoring and
reporting requirements to determine customer compliance; reevaluation and improvement
procedures for evaluating the WSCP.
• Drought Risk Assessment— Suppliers are now required to compare their total water use and
supply projections, and conduct a reliability assessment of all their water sources for a
consecutive five-year drought period beginning 2021.
• Five Consecutive Dry-Year Water Reliability Assessment- The three-year multiple dry year
reliability assessment in previous UWMPs was changed from three (3) to five (5) consecutive dry
years to include a more comprehensive assessment of water source reliability to improve
Supplier preparedness for extended drought conditions.
• Seismic Risk —The UWMP now includes a seismic risk assessment of water supply
infrastructure along with a plan to mitigate any potential seismic risks to water supply assets.
• Groundwater Supplies Coordination —The UWMP should be in accordance with the
Sustainable Groundwater Management Act of 2014 and consistent with the Groundwater
Sustainability Plans, wherever applicable.
• Lay Description —To provide a better understanding of the UWMP to the general public, a lay
description of the UWMP is included, especially summarizing the Supplier's detailed water
service reliability assessment and the planned management steps and actions to mitigate any
possible shortage scenarios.
1 .2 UWMP Organization
This UWMP is organized into 10 main sections aligned with the DWR Guidebook recommendations.
The subsections are customized to tell the City's story of water supply reliability and ways to overcome
any water shortages over a 25-year planning horizon.
Section 1 Introduction and UWMP Overview gives an overview of the UWMP fundamentals and briefly
describes the new additional requirements passed by the Legislature for 2020 UWMP.
Section 2 UWMP Preparation identifies this UWMP as an individual planning effort of the City, lists the
type of year and units of measure used and introduces the coordination and outreach activities conducted
by the City to develop this UWMP.

Section 3 System Description gives a background on the City's water system and its climate
characteristics, population projection, demographics, socioeconomics and predominant current and
projected land uses of its service area.
Section 4 Water Use Characterization provides historical, current, and projected water use by customer
category for the next 25 years within the City's service area and the projection methodology used by
MWDOC to develop the 25-year projections.
Section 5 Conservation Target Compliance reports the SB X7-7 water use conservation target
compliance of the City (individually and as a member of the OC 20x2020 Regional Alliance).
Section 6 Water Supply Characterization describes the current water supply portfolio of the City as well
as the planned and potential water supply projects and water exchange and transfer opportunities.
Section 7 Water Service Reliability and Drought Risk Assessment assesses the reliability of the
City's water supply service to its customers for a normal year, single dry year, and five consecutive dry
years scenarios. This section also includes a DRA of all the supply sources for a consecutive five-year
drought period beginning 2021.
Section 6 Water Shortage Contingency Planning is a brief summary of the standalone WSCP
document (Appendix H) which provides a structured guide for the City to deal with water shortages,
incorporating prescriptive information and standardized action levels, lists the appropriate actions and
water use efficiency measures to be taken to ensure water supply reliability in times of water shortage
conditions, along with implementation actions in the event of a catastrophic supply interruption.
Section 9 Demand Management Measures provides a comprehensive description of the water
conservation programs that the City has implemented, is currently implementing, and plans to implement
in order to meet its urban water use reduction targets.
Section 10 Plan Adoption, Submittal, and Implementation provides a record of the process the City
followed to adopt and implement its UWMP.

2 UWMP PREPARATION
The City's 2020 UWMP is an individual UWMP for the City to meet the Water Code compliance as a retail
water supplier. While the City opted to prepare its own UWMP and meet Water Code compliance
individually, the development of this UWMP involved close coordination with its whole supplier.
MWDOC along with other key entities within the region.
2.1 Individual Planning and Compliance
All water suppliers in Orange County opted to prepare their own UWMP and comply with the Water Code
individually, including the City (Table 2-1) The City closely coordinated with MWDOC and various key
entities as discussed in Section 2 2 to ensure regional integration The UWMP Checklist was completed
to confirm the compliance of this UWMP with the Water Code (Appendix A).
One consistency with MWDOC and the majority of its other retail member agencies is that the City
selected to report demands and supplies using fiscal year (FY) basis (Table 2-2).

including MWDOC (regional wholesale supplier for Orange County), MET (regional wholesaler for
Southern California and the direct supplier of imported water to MWDOC), and OCWD (OC Basin
manager). The City also developed this Plan in conjunction with other MWDOC-led efforts such as
population projection from the Center for Demographic Research at California State University
Fullerton (CDR).
Some of the key planning and reporting documents that were used to develop this UWMP 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 OC 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 Draft 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 Groundwater Reliability Plan (to be finalized after July 2021) provides the latest
information on groundwater management and supply projection for the OC Basin, the primary
source of groundwater for 19 retail water suppliers in OC.
• OCWD's 2019-20 Engineer's Report provides information on the groundwater conditions and
basin utilization of the 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.
• Local Hazard Mitigation Plan 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 comprehensive review of the municipal services provided by MWDOC.
• Water Master Plan of the City provides information on water infrastructure planning projects and
plans to address any required water system improvements.
Statewide Water Planning
In addition to regional coordination with various agencies described above, the City as a MWDOC
member agency is currently a part of MET's statewide planning effort to reduce reliance on the water
imported from the Delta.
It is the policy of the Stale of California to reduce reliance on the Delta in meeting California's future water
supply needs through a statewide strategy of investing in improved regional supplies, conservation, and
water use efficiency. This policy is codified through the Delta Stewardship Council's Delta Plan Policy
WR P1 and is measured through Supplier reporting in each Urban Water Management Planning cycle.
WR P1 is relevant to water suppliers that plan to participate in multi-year water transfers, conveyance
facilities, or new diversions in the Delta.

water use and radial water use projections data to MWDOC (Table 2-3) MWDOC facilitated in refining the
projections of the City's water demand and the imported supply from MWDOC over the next 25 years.
The City also has taken part in many regional programs administered by MWDOC to assist retail
agencies meet various State compliance, such as the OC Regional Alliance for SB x7-7 compliance,
regional water loss program for SB555 compliance, and regional water use efficiency programs.
Sections 5 and 9 provide detailed information on these programs

3 SYSTEM DESCRIPTION
The City was incorporated in 1909 and is governed by a seven-member elected City Council. In 1964, the
City's Water Division was established as a Division of the Public Works Department. In 2003, the Public
Works Wastewater Section was incorporated into the Water Division to form the Utilities Division.
The City's water service area covers 27.3 square miles, along the Southern California Coast of Orange
County, located 35 miles southeast of Los Angeles and 90 miles northwest of San Diego. The City's
Public Works Department operates four storage and distribution reservoirs with a combined capacity of
55 million gallons (MG), four booster stations, eight active groundwater wells and manages 607.2-mile
water mains system with 55,028 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 mostly developed and is a predominantly single and multi-family residential community. Moving
forward, new development will occur as a result of market response to changing conditions such as
population growth, demographics, and the economy as well as the need to replace aging buildings and
improve homes. The City will continue planning for its Regional Housing Needs Assessment (RHNA)
allocation and future planned developments may potentially include accessory dwelling units (ADUs). The
current population of 201,327 is projected to increase by only 2.3% over the next 25 years.
3.1 Agency Overview
This section provides information on the formation and history of the City, its organizational structure, and
relationship to MWDOC.
3.1.1 Formation
The City is a predominantly residential community located along the California coastline in Orange
County. It was incorporated in 1909 and is a charter city. From 1936 to 1964, the water system serving
the City was owned and operated by the Southern California Water Company. In 1964, the City
purchased the private system and the City's Water Division was established as a Division of the Public
Works Department. In 2003, the Public Works Wastewater Section was incorporated into the Water
Division to form the Utilities Division.
3.1.2 City Council
The City is administered under a council/administrator form of government and is governed by a
seven -member elected City council, with part time council members. Current City Council members are:

NOTES:
3.3 Climate
The City is located within the SCAB that encompasses all of Orange County, and the urban areas of Los
Angeles, San Bernardino, and Riverside counties The SCAB climate is characterized by southern
California's "Mediterranean" climate a semi-arid environment with mild winters, warm summers, and
moderate rainfall.
Local rainfall has limited impacts on reducing water demand in the City, except for landscape irrigation
demand Water that infiltrates into the soil may enter groundwater supplies depending on the local
geography However, due to the large extent of impervious cover in southern California, rainfall runoff
quickly flows to a system of concrete storm drains and channels that lead directly to the ocean OCWD is
one agency that has successfully captured stormwater along the Santa Ana River and in recharge basins
for years and used it as an additional source of supply for groundwater recharge. Based on the
2017 Basin 8-1 Alternative Plan, OCWD captured an average annual stormwater volume of
approximately 44,000 AF over the period of ten years, from Water Year 2006-07 to 2015-16, however,
this penod's rainfall was 17% below the long term average using San Bernardino precipitation data.
Based on a longer period (1989-2015) of rainfall and captured stormwater records, the average year
water budget of OCWD assumes a stormwater capture volume of 52,000 AF.

3.4 Population, Demographics, and Socioeconomics
3.4.1 Population
According to CDR, the City's service area has a 2020 population of 201,327, an increase from the
2015 population of 197,787, The City is almost completely built-out and overall, the population is
projected to increase with a moderate growth of 2.3% over the 25-year period from 2020 to 2045 due to
dens cation of existing communities. The growth is slightly higher in the first 15 years until 2035 and
tapered off from there. Table 3-2 shows the population projections in five-year increments out to
2045 within the City's service area.

3.4.2 Demographics and Socioeconomics
As shown in Table 3-3 below, the total number of dwelling units in the City is expected to increase by
1.4% in the next 25 years from 82.524 in 2020 to 83.693 in 2045. Table 3-3 also shows a breakdown of

Huntington Beach 2020 Urban Water Management Plan
In addition to the types and proportions of dwelling units, various socio-economic factors such as age
distribution, education levels, general health status, income and poverty levels affect City's water
management and planning. Based on the U.S. Census Bureau's QuickFacts, the City has about 17.6% of
population of 65 years and over, 19.2% under the age of 18 years and 5.3% under the age of 5 years.
92.7% of the City's population with an age of more than 25 years has a minimum of high school graduate
and 42.6% of this age group has at least a bachelor's degree.
3.4.3 CDR Projection Methodology
The City obtains its services area population and dwelling unit data from MWDOC via CDR.
MWDOC contracts with CDR to update the historic population estimates for 2010 to the current year and
provide an annual estimate of population served by each of its retail water suppliers within its service
area. CDR uses GIS and data from the 2000 and 2010 U.S. Decennial Censuses, State Department of
Finance (DOF) population estimates, and the CDR annual population estimates. These annual estimates
incorporate annual revisions to the DOF annual population estimates, often for every year back to the
most recent Decennial Census. As a result, all previous estimates were set aside and replaced with the
most current set of annual estimates. Annexations and boundary changes for water suppliers are
incorporated into these annual estimates.
In the summer of 2020, projections by water supplier for population and dwelling units by type were
estimated using the 2018 Orange County Projections dataset. Growth for each of the five-year increments
was allocated using GIS and a review of the traffic analysis zones (TAZ) with a 2019 aerial photo.
The growth was added to the 2020 estimates by the water supplier.
3.5 Land Uses
3.5.1 Current Land Uses
The City's service area can best be described as a predominantly single and multi-family residential
community located along the coast in northern Orange County. There is a large number of visitors to the
City throughout the year to take advantage of the miles of coastline and beachfront activities.
Existing land uses in the City include a mix of residential, commercial, industrial, mixed use, parks, open
space (e.g., wetlands, beaches), oil-related, and public uses. According to the General Plan Land Use
Element, residential development is the predominant use in the City; housing uses constitute about 43%
of all land uses in the planning area. Public uses, primarily comprising public rights-of-way, occupy an
additional 28% of the planning area. Open space, commercial, and industrial development occupies most
of the remainder of the planning area. There is very little vacant land available within the City, therefore,
most growth is occurring through redevelopment of existing developed land.
Figure 3-3 shows the land use designations in the City based on the 2040 General Plan, which was
adopted in 2017. As most of the planning area is already developed and maintained in good condition,
the designations generally correspond to the pattern of existing uses.

Pursuant to the General Plan, land use in the City is being developed in accordance with the General
Plan land use designation of each property The General Plan land use designation specifies the uses,
density, and intensity of development allowed on each property. In addition, there are 17 adopted specific
plans in the City These plans have predominantly been used to focus on the characteristics unique to a
particular area and customize the planning process and land use regulations and requirements that apply
3-8
914
Huntington Beach 2020 Urban Water Management Plan
within that specific plan area. Two of the largest specific plans are the Beach and Edinger Corridors
Specific Plan and the Downtown Specific Plan.
3.5.2 Projected Land Uses
The City is mostly built-out and moving forward, new development will occur as a result of market
response to changing conditions such as population growth, demographics, and the economy as well as
the need to replace aging buildings and improve homes. The 2017 General Plan anticipated a modest
amount of growth through 2040, with most residential growth occurring in specific plan areas and non-
residential growth occurring through implementation of a new Research and Technology land use
designation as further described below.
Figure 3-4 indicates where change is encouraged to occur to accommodate future growth and
development under the City's General Plan and to what degree it can be expected. As shown in the
diagram, most areas in the City are proposed to remain much as they are today or would transform
through guidelines provided by documents other than the General Plan. The terms used to describe the
planned levels of change range from very little ("Preserve" and "Conserve") to substantial ("Transform").

Huntington Beach 2020 Urban Water Management Plan
"Preserve" areas are developed portions of Huntington Beach, where land use changes are not
envisioned and are not necessary to implement the Community Vision. Preserve areas include all
established residential neighborhoods, most commercial, retail, and employment centers, many
visitor-serving commercial uses; and all of the Downtown area.
"Conserve" areas include open space and recreational areas that provide valuable natural habitat or
parkland and support the community recreational and aesthetic needs. This category includes the beach,
the Bolsa Chica Wetlands, parks, golf courses, and other similar uses.
"Transform" areas consist of underdeveloped or underutilized portions of the planning area, where current
developments might not adequately support future City goals. These areas are located within the
Northwest Industrial Area and along the Gothard Corridor, where a majority of the city's industrial uses
are located. The General Plan established a new land use designation, Research and Technology, to
enable a broader mix of lower-intensity industrial and commercial uses that better meet current and future
market demands, and capture employment growth in emerging fields. Additional areas in the City could
transform via means other than those established within the General Plan (e.g., specific plan areas).
In addition to land use and growth anticipated by the 2017 General Plan, the City must plan for future
regional housing growth. State law requires jurisdictions to plan for their share of the RHNA. The
Southern California Association of Governments (SCAG) determines the housing growth needs by
income for local jurisdictions through the RHNA process. The City's RHNA allocation for the 2021 - 2029
planning period is 13,368 units. This includes 3,661 units for very low-income households, 2,184 units for
low-income households, 2,308 units for moderate-income households, and 5,215 units for above
moderate-income households. It should be noted that the City's RHNA targets for 2021-2029 reflect
greater residential growth than is anticipated in the 2017 General Plan, which has a horizon year of 2040.
The City is currently updating the General Plan Housing Element to identify where in the City 13,368 units
can be accommodated. As such, it is likely that areas of the City with existing residential land use
designations will change to higher density residential designations and areas with nonresidential land use
designations will convert to residential or mixed use. To that end, amendments to the land use map
shown in Figure 3-3 will probably occur in the next one to three years.
Finally, as part of the state's response to an ongoing housing crisis, many new laws with the goal of
increasing housing supply have been passed by the legislature in the last several years. Some of these
laws have addressed regulations for ADUs, which are attached or detached independent living units on
the same property as the primary dwelling unit or units, by requiring jurisdictions to make them easier to
permit. As such, in accordance with state law, all residential properties, including single-family residential
properties, are permitted to have ADUs by right. Since the laws to ease regulations on ADUs have
passed, there has been an increase in the construction of ADUs in the City and statewide. Of note,
approximately 92% of the ADUs in California are being built in the single family zoned parcels (University
of California Berkeley, 2020). The increase in ADUs implies an increase in number of people per dwelling
unit which potentially translates to higher water demand.

4 WATER USE CHARACTERIZATION
4.1 Water Use Overview
Water use within the City's service area has been relatively stable in the past decade with an annual
average of 27,753 AF for potable use. In FY 2019-20, the City's water use was 25,966 AF of potable
water (groundwater and imported). There is currently no recycled water use within the City's service area.
As described in Section 3, the City mostly developed and is a predominantly single and multi-family
residential community, with a small projected population increase of 2.3% over the next 25 years. Water
demand is likely to increase 1.7% over the next five years. In the longer term, water demand is projected
to decrease 1.3% from 2025 through 2045. The projected potable water use for 2045 is 26,054 AF. The
passive savings are anticipated to continue for the next 25 years and are considered in the water use
projections. Permanent water conservation requirements and water conservation strategies are discussed
in Section 8 and 9 of this document.
4.2 Past and Current Water Use
Water use within the City's service area has been relatively stable in the past decade with an annual
average of 27,753 AF. A stable trend is expected because the city is essentially built-out and the rate of
population growth is expected to average less than 0.1% per year for the next 25 years. Water
conservation efforts also kept per capita water use down.
As a result of Governor Jerry Brown's mandatory water conservation order in 2014, retail water use within
the City's service area has been decreased from the average of 29,356 AF (FY2010/11 and FY2014/15)
to the last five-year average of 26.150 (FY2015/16 and FY2019/20). Between FY2015/16 and FY2019/20,
water use within the City's service area ranged from 24,717 to 27,720 AFY.
All the water use within the City is for potable use and there is currently no recycled water use within the
City's service area because the City currently does not have infrastructure in place for recycled water. As
of FY2019/20, there are 55,028 current customer active and inactive service connections in the City's
water distribution system with all existing connections metered. Table 4-1 summarizes the City's total
water use for FY2019/20.
For FY 2019-20, 18,206 AF (or 70.1%) of the City's potable water demand was residential, with
commercial, industrial, institutional/governmental, dedicated landscape, and losses accounting for the
remaining 29.8% of the total potable water demand. The City has a mix of commercial uses
(markets, restaurants, etc.), public entities (schools, fire stations and government offices), office
complexes, light industrial and warehouses. Commercial water use accounts for 3,240 AF (or 12.5%) of
total water demands and dedicated landscape for 2,141 AF (or 8.2%) of total water demand. Industrial
and institutional/governmental uses make up about 741 AF (2.9%) of total demand. Non-revenue water
comprises 6.3% of total water demand. Non-revenue water includes real losses (e.g., leakage in mains
and service lines, and storage lank overflows), apparent losses (unauthorized consumption, customer
metering inaccuracies and systematic data handling errors), and unbilled water (e.g., hydrant flushing,
firefighting, and blow-off water from well start-ups).

4.3 Water Use Projections
A key component of this 2020 UWMP is to provide an insight into the City's future water demand outlook.
This section discusses the considerations and methodology used to estimate the 25-year water use
projection. Overall, total water demand is projected to decrease 11.1% between 2020 and 2045.
Single and multifamily residential use is projected to decrease in the same timeframe. Commercial,
institutional, and industrial(CII) use is projected to decrease slightly. Demands for large landscape
applications are projected to increase, while projections for non-revenue water loss decrease.
4.3.1 Water Use Projection Methodology
In 2021. MWDOC and OCWD, in collaboration with their member agencies, led the effort to update water
demand projections originally done as part of the 2021 OC Water Demand Forecast for MWDOC and
OCWD (Appendix E). The updated demand projections, prepared by CDM Smith, were for the Orange
County region as a whole, and provided retail agency specific demands. The projections span the years
of 2025-2050 and are based upon information surveyed from each Orange County water agency.
a,cad,s com
4-2
919
Huntington Beach 2020 Urban Water Management Plan
The forecast methodology began with a retail water agency survey that asked for FY 2017-18, FY 2018-19
and FY 2019-20 water use by major sector, including number of accounts. If a member agency provided
recycled water to customers that information was also requested. Given that FY 2017-18 was a slightly
above-normal demand year (warmer/drier than average) and FY 2018-19 was a slightly below-normal
demand year (cooler/wetter than average), water use from these two years were averaged to represent an
average-year base water demand.
For the residential sectors (single-family and multifamily) the base year water demand was divided by
households in order to get a total per unit water use (gallons per home per day). In order to split
household water use into indoor and outdoor uses, three sources of information were used, along with
CDM Smith's expertise. The sources of information included: (1) the Residential End Uses of Water
(Water Research Foundation, 2016); (2) California's plumbing codes and landscape ordinances; and (3)
CA DWR's Model Water Efficient Landscape Ordinance (MWELO) calculator.
Three different periods of residential end uses of water were analyzed as follows:
• Pre-2010 efficiency levels — Has an average indoor water use that is considered to be
moderately efficient, also does not include the most recent requirements for MWELO.
• High-efficiency levels — Includes the most recent plumbing codes that are considered to be
highly efficient, and also includes the most recent requirements for MWELO.
• Current average efficiency levels — Represents the weighted average between pre-2010
efficiency and high efficiency levels, based on average age of homes for each retail water
agency.
For outdoor residential water use, the indoor per capita total was multiplied by each member agency-
specific persons per household in order to get an indoor residential household water use (gallons per day
per home), and then was subtracted from the base year total household water use for single-family and
multifamily for each agency based on actual water use as reported by the agency surveys.
For existing residential homes, the current average indoor and outdoor water use for each member
agency were used for the year 2020. It was assumed that indoor water uses would reach the high
efficiency level by 2040. Based on current age of homes, replacement/remodeling rates, and water utility
rebate programs it is believed this assumption is very achievable. It was also assumed that current
outdoor water use would be reduced by 5% by 2050.
For new homes, the indoor high efficiency level was assumed for the years 2025 through 2050. Outdoor
uses for new homes were assumed to be 25% and 30% lower than current household water use for
single-family and multifamily homes, respectively. This methodology is illustrated in Figure 4-1 below.

Existing and projected population, single-family and multifamily households for each retail water agency
were provided by CDR under contract by MWDOC and OCWD CDR provides historical and future
demographics by census tracts for all of Orange County (Section 3.4) Census tract data is then clipped
to retail water agency service boundaries in order to produce historical and projected demographic data
by agency
For the CII water demands. which have been fairly stable from a unit use perspective (gallons/account/day),
it was assumed that the unit demand in FY 2019-20 would remain the same from 2020-2025 to represent
COVID-19 impacts Reviewing agency water use data from FY 2017-18 through FY2019-20 revealed that
residential water use increased slightly in FY 2019-20 while CII demands decreased slightly as a result of
COVID-19. From 2030 to 2050. the average CII unit use from FY 2017-18 and 2018-19 was used. These
unit use factors were then multiplied by an assumed growth of CII accounts under three broad scenarios
• Low Scenario - assuming no growth in CII accounts
• Mid Scenario - assuming 0.5% annual growth in CII accounts
• High Scenario -assuming 1.5% annual growth in CII accounts
For most retail agencies. the Mid Scenario of CII account growth was used, but for those retail agencies
that have had faster historical growth the High Scenario was used. For those retail agencies that have
had relatively stable CII water demand. the Low Scenario was used. For Huntington Beach, the mid-
scenario was used
For those agencies that supply recycled water for non-potable demands. MWDOC used agency-specified
growth assumptions Most agencies have already maximized their recycled water and thus are not
expecting for this category of demand to grow However, a few agencies In South Orange County do
expect moderate growth in recycled water customers
For large landscape customers served currently by potable water use. MWDOC assumed these demands
to be constant through 2050, except for agencies that have growing recycled water demands. For the
agencies that have growing recycled water demands, large landscape demands served by potable water

reduced accordingly. For non-revenue water, which represents the difference in total water production
less all water billed to customers, this percentage was held constant through 2050. Note that 2050 data
was not presented in the UWMP.
A member agency's water use demand projection is the summation of their residential water demand, CII
demands, large landscape and recycled water demands, and water losses all projected over the 25-year
time horizon. These demands were provided to each of the Orange County water agencies for their
review, feedback, and revision before being finalized.
The MWDOC regional water demand projection was collaboratively developed between MWDOC and its
member agencies. MWDOC's projections were built upon the same model developed by CDM Smith, and
took into consideration specific assumptions and projections provided to MWDOC by its member
agencies.
4.3.1.1 Weather Variability and Long-Term Climate Change Impacts
In any given year water demands can vary substantially due to weather. In addition, long-term climate
change can have an impact on water demands into the future. For the 2014 OC Water Reliability Study,
CDM Smith developed a statistical model of total water monthly production from 1990 to 2014 from a
sample of retail water agencies. This model removed impacts from population growth, the economy and
drought restrictions in order to estimate the impact on water use from temperature and precipitation.
The results of this statistical analysis are:
• Hot/dry weather demands will be 5.5% greater than current average weather demands
• Cooler/wet weather demands will be 6% lower than current average weather demands
• Climate change impacts will increase current average weather demands by:
o 2% in 2030
o 4% in 2040
o 6% in 2050
4.3.2 25-Year Water Use Projection
The projected demand values were provided by MWDOC and reviewed by the City as part of the UWMP
effort. As the regional wholesale supplier for much of Orange County, MWDOC works in collaboration
with each of its retail agencies as well as MET, its wholesaler, to develop demand projections for
imported water. The City has been proactively decreasing its reliance on imported water by pursuing a
variety of water conservation strategies within the service area. Future water savings and low -income
water use are included in these projected values.
4.32.1 Water Use Projections for 2021-2025
The water use projection for normal year conditions without drought conditions for 2021-2025 is
presented in Table 4-2. A linear decrease in total water demand is expected between 2021 and 2025.
Total water demand is expected to be 26,399 AF in 2025 (a decrease of 9.9% from 2020 actual usage).
This table will be adjusted to estimate the five-years' cumulative drought effects as described in the
five-year DRA in Section 7.

4.3.2.2 Water Use Projections for 2025-2045
Table 4-3 is a projection of the City's water demand for 2025-2045. Single family and mufti-family usage
are both projected to decrease in this timeframe, while CII usage is expected to increase. CII projections
for 2025 through 2045 were broken down into commercial, industrial, and institutional/governmental using
proportions reported for each billing sector in FY 2019-20. Demands for large landscape applications are
projected to stay relatively consistent, while projections for NRW loss gradually decrease. These
projected demand values were provided by MWDOC and reviewed by the City as part of the UWMP
effort. As the regional wholesale supplier for much of Orange County. MWDOC works in collaboration
with each of its retail agencies as well as MET, its wholesaler, to develop demand projections for
imported water. The City has been proactively decreasing its reliance on imported water by pursuing a
variety of water conservation strategies. Future water savings and low-income water use are included in
these projected values (Table 4-5).
The demand data presented in this section accounts for passive savings in the future. Passive savings
are water savings as a result of codes, standards, ordinances and public outreach on water conservation
and higher efficiency fixtures. Passive savings are anticipated to continue through 2045 and will result in
continued water saving and reduced consumption levels. Permanent water conservation requirements
and water conservation strategies are discussed in Section 8 and 9 of this document.

NOTES:
4.3.2.3 Water Use Projections for Lower Income Households
Since 2010, the UWMP Act has required retail water suppliers to include water use projections for single-
family and multi-family residential housing for lower income and affordable households. This will assist the
City in complying with the requirement under Government Code Section 65589.7 granting priority for
providing water service to lower income households. A lower income household is defined as a
household earning below 80% of the median household income (MHI)
DWR recommends retail suppliers rely on the housing elements of city or county general plans to quantify
planned lower income housing with the City's service area (DWR. 2020) RHNA assists jurisdictions in
updating general plan's housing elements section. The RHNA identifies additional housing needs and
assesses households by income level for the City through 2010 decennial Census and 2005-2009
American Community Survey data The sixth cycle of the RHNA covers the planning period of October
2021 to October 2029 The SCAG adopted the RHNA Allocation Plan for this cycle on March 4. 2021
The California Department of Housing and Community Development reviewed the housing elements data
submitted by jurisdictions In the SCAG region and concluded the data meets statutory requirements for
the assessment of current housing needs.

924
Huntington Beach 2020 Urban Water Management Plan
Under the assumption that the RHNA household allocations adequately represent ratios of the City's
overall future income categories (not the exact ratio of all household by income but a conservative one for
low-income household estimates), the RHNA low-income percentage can be used to estimate future low
income demands One objective of RHNA is to increase affordable housing, therefore RHNA has been
allocating additional low-income households to various regions. Because relying on the RHNA distribution
of households by income category is likely to produce an overestimate of low-income water demands, this
approach represents a conservative projection of future low-income water use.
Table 4-6 presents the City's RHNA housing allocation RHNA classifies low income housing into two
categories very low income (<30% - 50% MHI), and low income (51% - 80% MHI) Altogether 43.7% of
the City's allocated housing need for the planning period of October 2021 to October 2029 are considered
low-income housing (SCAG. 2021)

Total Future Allocated Households 13,368 100.0%
By applying the percentage of low-income housing from the SCAG report to the total projected SF/MF
residential demand calculated in Table 4-3 above, low-income demand can be conservatively estimated
for both SF and MF through 2045 For example, the total low-income single family residential demand is
projected to be 5,122 AF in 2025 and 4.849 AF in 2045 (Table 4-7).

The City has conducted annual water loss audit since 2015 per the American Water Works Association
(AWWA) methodology per SB 555 to understand the relationship between water loss, operating costs.

and revenue losses Non-revenue water for FY2014/15- CY 2019 (excluding CY 2016 and 2017 due to
negative reported real loss values associated with billing system errors) (Figure 4-2) consists of three
components: real losses (e g , leakage in mains and service lines. and storage tank overflows), apparent
losses (unauthorized consumption, customer metering inaccuracies and systematic data handling errors).
and unbilled water (e g., hydrant flushing. firefighting. and blow-off water from well start-ups). The City's
real losses ranged from 902 AFY to 1389 AFY and apparent losses ranged from 185 AFY to 247AFY
from FY2014/15 - CY 2019 (once again excluding CY 2016 and 2017). The water audit data from
CY2016 and CY2017 are not included in the discussion because the real loss was -85 and -2531 AFY,
respectively. The unbilled water ranged from 64 AFY to 68 AFY in the same time frame.
In the CY2019 water audit. the City's total water loss was 1.574 AFY (Table 4-8) compared to the total
water use of 25,912 AF in the same timeframe The total water loss consists of real loss of 1389 AFY and
apparent loss of 185 AFY in CY2019 The non-revenue water was 1638 AFY. The active and inactive
service connections were relatively consistent from CY2015-2019 with 55,088 connections in CY2019.
The real loss performance indicator was 23 gals/connection/day in CY2019. Figure 4-3 presents the
performance indicators of gallons of real and apparent loss per connection per day. Understanding and
controlling water loss from a distribution system is an effective way for the City to achieve regulatory
standards and manage their existing resources The California State Water Resources Control Board
(SWRCB) is still developing water loss performance standards, these standards have not yet been
adopted.

5 CONSERVATION TARGET COMPLIANCE
The Water Conservation Act of 2009, also known as SBx7-7 (Senate Bill 7 as part of the Seventh
Extraordinary Session), signed into law on February 3, 2010, requires the State of California to reduce
urban water use by 20% by the year 2020 (20x2O2O). To achieve this each retail urban water supplier
must determine baseline water use during their baseline period and target water use for the years 2015
and 2020 to meet the state's water reduction goal. Retail water suppliers are required to comply with
SBx7-7 individually or as a region in collaboration with other retail water suppliers, or demonstrate they
have a plan or have secured funding to be in compliance, in order to be eligible for water related state
grants and loans on or after July 16, 2016.
The City's actual 2020 water use is lower than its 2020 water use target, therefore, demonstrating
compliance with SBx7-7. In its 2015 UWMP, the City revised its baseline per capita water use calculations
using 2010 U.S. Census data. Changes in the baseline calculations resulted in updated per capita water
use targets.
The following sections describe the efforts by the City to comply with the requirements of SBx7-7 and
efforts by MWDOC to assist retail agencies, including the formation of a Regional Alliance to provide
additional flexibility to all water suppliers in Orange County. A discussion of programs implemented
to support retail agencies in achieving their per capita water reduction goals is covered in Section 9 —
Demand Management Measures of this UWMP.
Complimentary to information presented in this section are SBx7-7 Verification and Compliance Forms, a
set of standardized tables required by DWR to demonstrate compliance with the Water Conservation Act
in this 2020 UWMP (Appendix D) including calculations of recycled water used for groundwater recharge
(indirect reuse) to offset a portion of the agency's potable demand when meeting the regional as well as
individual water use targets.
5.1 Baseline Water Use
The baseline water use is the City's gross water use divided by its service area population, reported in
GPCD. Gross water use is a measure of water that enters the distribution system of the supplier over a
12-month period with certain allowable exclusions. These exclusions are:
• Recycled water delivered within the service area
• Indirect recycled water
• Water placed in long term storage
• Water conveyed to another urban supplier
• Water delivered for agricultural use
• Process water
Water suppliers within the OCWD Groundwater Basin, including the City, have the option of choosing to
deduct recycled water used for indirect potable reuse (IPR) from their gross water use to account for the
arcacis com
5-1
928
Huntington Beach 2020 Urban Water Management Plan
recharge of recycled water into the OC Basin by OCWD, historically through Water Factory 21 (WF-21),
and now by the Groundwater Replenishment System (GWRS).
Water suppliers must report baseline water use for two baseline periods, the 10- to 15-year baseline
(baseline GPCD) and the five-year baseline (target confirmation) as described below.
5.1.1 Ten to 15-Year Baseline Period (Baseline GPCD)
The first step to calculating the City's water use targets is to determine its base daily per capita water use
(baseline water use). The baseline water use is calculated as a continuous (rolling) 10-year average
during a period, which ends no earlier than December 31, 2004 and no later than December 31, 2010.
Water suppliers whose recycled water made up 10% or more of their 2008 retail water delivery can use
up to a 15-year average for the calculation. Recycled water use was less than 10% of the City's retail
delivery in 2008; therefore, a 10-year baseline period is used.
The City's baseline water use is 161 GPCD, obtained from the 10-year period July 1, 1995 to June 30,
2005. Calculations are provided in Appendix D.
5.1.2 Five-Year Baseline Period (Target Confirmation)
Water suppliers are required to calculate water use, in GPCD, for a five-year baseline period. This number
is used to confirm that the selected 2020 target meets the minimum water use reduction requirements.
Regardless of the compliance option adopted by the City, it will need to meet a minimum water use target
of 5% reduction from the five-year baseline water use. This five-year baseline water use is calculated as
a continuous five-year average during a period, which ends no earlier than December 31, 2007 and no
later than December 31, 2010. The City's five-year baseline water use is 151 GPCD, obtained from the
five-year period July 1, 2003 to June 30, 2008. Calculations are provided in Appendix D.
5.1.3 Service Area Population
The City's service area boundaries correspond with the boundaries for a city or census designated place.
This allows the City to use service area population estimates prepared by the DOF. CDR is the entity
which compiles population data for Orange County based on DOF data. The calculation of the City's
baseline water use and water use targets in the 2010 UWMP was based on the 2000 U.S. Census
population numbers obtained from CDR. The baseline water use and water use targets in the 2015
UWMP were revised based on the 2010 U.S. Census population obtained from CDR in 2012. That
baseline remained in use in the 2020 calculations.
5.2 SBx7-7 Water Use Targets
In the 2020 UWMP, the City may update its 2020 water use target by selecting a different target method
than what was used previously. The target methods and determination of the 2015 and 2020 targets are
described below. The City selected Option 3 consistent with 2015 and maintained the same 2015 and
2020 target water uses as reported in its 2015 UWMP.

Huntington Beach 2020 Urban Water Management Plan
5.2.1 SBx7-7 Target Methods
DWR has established four target calculation methods for urban retail water suppliers to choose from
The City is required to adopt one of the four options to comply with SBx7-7 requirements The
four options include:
• Option 1 requires a simple 20% reduction from the baseline by 2020 and 10% by 2015.
• Option 2 employs a budget-based approach by requiring an agency to achieve a performance
standard based on three metrics
Residential indoor water use of 55 GPCD
Landscape water use commensurate with the Model Landscape Ordinance
10% reduction in baseline CII water use
• Option 3 is to achieve 95% of the applicable state hydrologic region target as set forth in the
State's 202020 Water Conservation Plan.
• Option 4 requires the subtraction of Total Savings from the baseline GPCD.
C Total savings includes indoor residential savings, meter savings. CII savings, and landscape
and water loss savings.
With MWDOC s assistance in the calculation of the City's base daily per capita use and water use targets,
the City selected to comply with Option 3 consistent with the option selected in 2010 and 2015
5.2.2 2020 Targets and Compliance
Under Compliance Option 3. to achieve 95% of the South Coast Hydrologic Region target as set forth in
the State's 20x2020 Water Conservation Plan,the City's 2015 target is 157 GPCD and the 2020 target is
142 GPCD as summarized in Table 5-1 In addition, the confirmed 2020 target needs to meet a minimum
of 5% reduction from the five-year baseline water use.

NOTES:
5.3 Orange County 20x2020 Regional Alliance
A retail supplier may choose to meet the SBx7-7 targets on its own or it may form a regional alliance with
other retail suppliers to meet the water use target as a region. Within a Regional Alliance, each retail
water supplier will have an additional opportunity to achieve compliance under both an individual target
and a regional target.
• If the Regional Alliance meets its water use target on a regional basis, all agencies in the alliance are
deemed compliant.
• If the Regional Alliance fails to meet its water use target, each individual supplier will have an
opportunity to meet their water use targets individually.
The City is a member of the Orange County 20x2020 Regional Alliance formed by MWDOC, its
wholesaler. This regional alliance consists of 29 retail agencies in Orange County as described in
MWDOC's 2020 UWMP. MWDOC provides assistance in the calculation of each retail agency's baseline
water use and water use targets.
In 2020, the regional baseline and targets were revised from 2015 to account for any revisions made by
the retail agencies to their individual 2020 targets. The regional water use target is the weighted average
of the individual retail agencies' targets (by population). The Orange County 20x2020 Regional Alliance
weighted 2020 target is 159 GPCD. The actual 2020 water use in the region is 109 GPCD, i.e., the region
met its 2020 GPCD goal.

6 WATER SUPPLY CHARACTERIZATION
As a counterpart to Section 4's Water Use Characterization, this section characterizes the City's water
supply This section includes identification and quantification of water supply sources through 2045,
descriptions of each water supply source and their management. opportunities for exchanges and
transfers, and discussion regarding any planned future water supply projects. This section also includes
the energy intensity of the water service, a new UWMP requirement.
6.1 Water Supply Overview
The City meets all of its demands with a combination of imported water and local groundwater 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 Orange County Groundwater Basin
Imported water makes up the rest of the City's water supply portfolio. In FY 2019-20, the City relied on
approximately 70% groundwater and 30% imported water (Table 6-1).
It is projected that by 2045. the water supply mix will change to approximately 85% groundwater and
15% imported water (Table 6-2 and Figure 6-1) Note that these representations of supply match the
projected demand However, the City can purchase more MET water through MWDOC, should the need
arise Additionally, GWRS supplies are included as part of groundwater pumping numbers
The following subsections provide a detailed discussion of the City s water sources as well as the future
water supply portfolio for the next 25 years

The City supplements its local groundwater with imported water purchased from MET through MWDOC.
Based on the most recent 10-year average, the annual imported water volume supplied in the City is
8,882 AFY. In FY 2019-20, the City relied on approximately 7,670 AFY — approximately 30% of the City's
water supply portfolio for FY 2019-20 —of imported water to meet its demands. MET's principal sources of
water are the Colorado River via the Colorado River Aqueduct (CRA) and the Lake Oroville watershed in
Northern California through the SWP. For Orange County, the water obtained from these sources is
treated at the Robert B. Diemer Filtration Plant located in Yorba Linda. Typically, the Diemer Filtration
Plant receives a blend of Colorado River water from Lake Mathews through the MET Lower Feeder and
SWP water through the Yorba Linda Feeder.
The City maintains three imported water connections to the MET system, OC-9 with a capacity of
14 cubic feet per second (cfs), OC-35 with a capacity of 20 cfs, and OC-44 with a capacity of 15 cfs.
OC-9 is located at the intersection of Dale and Katella Streets in the City of Stanton and enters the City at
the intersection of Newland and Edinger Streets. OC-35 is also located at the intersection of Dale and
Katella Streets, and enters the City at the intersection of Springdale and Glenwood Streets. OC- 9 and
OC-35 are under the jurisdiction of the West Orange County Water Board. OC-44 is located at the
East Orange County Feeder#2, and flow is delivered to the City's service area through a 24- to 42-inch
transmission main jointly owned by the City and Mesa Water District. A secondary metering station, also
jointly owned, is located on Adams Avenue at the Santa Ana River.
6.2.1 Colorado River Supplies
Background
The Colorado River was MET's original source of water after MET's establishment in 1928. The CRA,
which is owned and operated by MET, transports water from the Colorado River to its terminus
Lake Mathews, in Riverside County. The actual amount of water per year that may be conveyed through
the CRA to MET's member agencies is subject to the availability of Colorado River water. Approximately
40 million people rely on the Colorado River and its tributaries for water with 5.5 million acres of land
using Colorado River water for irrigation. The CRA includes supplies from the implementation of the
Quantification Settlement Agreement and its related agreements to transfer water from agricultural
agencies to urban uses. The 2003 Quantification Settlement Agreement enabled California to implement
major Colorado River water conservation and transfer programs, in order to stabilize water supplies and
reduce the state's demand on the river to its 4.4 million acre-feet (MAF) entitlement. Colorado River
transactions are potentially available to supply additional water up to the CRA capacity of 1.25 MAF on an
as-needed basis. Water from the Colorado River or its tributaries is available to users in California,
Arizona, Colorado, Nevada, New Mexico, Utah, Wyoming, and Mexico. California is apportioned the use
of 4.4 MAF of water from the Colorado River each year plus one-half of any surplus that may be available
for use collectively in Arizona, California, and Nevada. In addition, California has historically been allowed
to use Colorado River water apportioned to, but not used by, Arizona or Nevada. MET has a basic
entitlement of 550,000 AFY of Colorado River water, plus surplus water up to an additional 662,000 AFY
when the following conditions exist (MET, 2021):
• Colorado River water is unused by the California holders of priorities 1 through 3

Huntington Beach 2020 Urban Water Management Plan
• Water is saved by the Palo Verde land management, crop rotation, and water supply program
• When the U.S. Secretary of the Interior makes available either one or both of the following:
o Surplus water
o Colorado River water that is apportioned to but unused by Arizona and/or Nevada.
Current Conditions and Supply
MET has not received surplus water for a number of years. The Colorado River supply faces current and
future imbalances between water supply and demand in the Colorado River Basin due to long-term
drought conditions. Analysis of historical records suggests a potential change in the relationship between
precipitation and runoff in the Colorado River Basin. The past 21 years (1999-2020) have seen an overall
drying trend, even though the period included several wet or average years. The river basin has
substantial storage capacity, but the significant reduction in system reservoir storage in the last two
decades is great enough to consider the period a drought (DWR, 2020a). At the close of 2020, system
storage was at or near its lowest since 2000, so there is very little buffer to avoid a shortage from any
future period of reduced precipitation and runoff(MET, 2021). Looking ahead, the long-term imbalance in
the Colorado River Basin's future supply and demand is projected to be approximately 3.2 MAF by the
year 2060 (USBR, 2012).
Over the years, MET has helped fund and implement various programs to improve Colorado River supply
reliability and help resolve the imbalance between supply and demand. Implementation of such programs
have contributed to achievements like achieving a record low diversion of the Colorado River in 2019. a
level not seen since the 1950s. Colorado River water management programs include:
• Imperial Irrigation District I MET Conservation Program — Under agreements executed in
1988 and 1989, this program allows MET to fund water efficiency improvements within Imperial
Irrigation District's service area in return for the right to divert the water conserved by those
investments. An average of 105,000 AFY of water has been conserved since the program's
implementation.
• Palo Verde Land Management, Crop Rotation, and Water Supply Program —Authorized in
2004, this 35-year program allows MET to pay participating farmers to reduce their water use,
and for MET to receive the saved water. Over the life of the program, an average of 84,500 AFY
has been saved and made available to MET.
• Bard Seasonal Fallowing Program —Authorized in 2019, this program allows MET to pay
participating farmers in Bard to reduce their water use between the late spring and summer
months of selected years, which provides up to 6,000 AF of water to be available to MET in
certain years.
• Management of MET-Owned Land in Palo Verde— Since 2001, MET has acquired
approximately 21,000 acres of irrigable farmland that are leased to growers, with incentives to
grow low water-using crops and experiment with low water-consumption practices. If long-term
water savings are realized, MET may explore ways to formally account them for Colorado River
supplies.
• Southern Nevada Water Authority (SNWA) and MET Storage and Interstate Release
Agreement— Entered in 2004, this agreement allows SNWA to store its unused, conserved
arcadis com
6-4
935
Huntington Beach 2020 Urban Water Management Plan
water with MET, in exchange for MET to receive additional Colorado River water supply. MET
has relied on the additional water during dry years, especially during the 2011-2016 California
drought, and SNWA is not expected to call upon MET to return water until after 2026.
• Lower Colorado Water Supply Projects —Authorized in 1980s, this project provides up to
10,000 AFY of water to certain entities that do not have or have insufficient rights to use Colorado
River water. A contract executed in 2007 allowed MET to receive project water left unused by the
project contractors along the River— nearly 10,000 AF was received by MET in 2019 and is
estimated for 2020.
• Exchange Programs — MET is involved in separate exchange programs with the United States
Bureau of Reclamation, which takes place at the Colorado River Intake and with San Diego
County Water Authority (SDCWA), which exchanges conserved Colorado River water.
• Lake Mead Storage Program — Executed in 2006, this program allows MET to leave excessively
conserved water in Lake Mead, for exclusive use by MET in later years.
• Quagga Mussel Control Program — Developed in 2007, this program introduced surveillance
activities and control measures to combat quagga mussels, an invasive species that impact the
Colorado River's water quality.
• Lower Basin Drought Contingency Plan — Signed in 2019, this agreement incentivizes storage
in Lake Mead through 2026 and overall, it increases MET's flexibility to fill the CRA as needed
(MET, 2021).
Future Programs / Plans
The Colorado River faces long-term challenges of water demands exceeding available supply with
additional uncertainties due to climate change. Climate change impacts expected in the Colorado River
Basin include the following:
• More frequent, more intense, and longer lasting droughts, which will result in water deficits
• Continued dryness in the Colorado River Basin, which will increase the likelihood of triggering a
first-ever shortage in the Lower Basin
• Increased temperatures, which will affect the percentage of precipitation that falls as rain or snow,
as well as the amount and timing of mountain snowpack (DWR, 20201b)
Acknowledging the various uncertainties regarding reliability, MET plans to continue ongoing programs,
such as those listed earlier in this section. Additionally, MET supports increasing water recycling in the
Colorado River Basin and is in the process of developing additional transfer programs for the future
(MET, 2021).
6.2.2 State Water Project Supplies
Background
The SWP consists of a series of pump stations, reservoirs, aqueducts, tunnels, and power plants
operated by DWR and is an integral part of the effort to ensure that business and industry, urban and
suburban residents, and farmers throughout much of California have sufficient water. Water from the
SWP originates at Lake Oroville, which is located on the Feather River in Northern California. Much of
arcadis corn
6-5
936
Huntington Beach 2020 Urban Water Management Plan
the SWP water supply passes through the Delta. The SWP is the largest state-built, multipurpose,
user-financed water project in the United States. Nearly two-thirds of residents in California receive at
least part of their water from the SWP, with approximately 70% of SWP's contracted water supply going
to urban users and 30% to agricultural users. The primary purpose of the SWP is to divert and store water
during wet periods in Northern and Central California and distribute it to areas of need in Northern
California, the San Francisco Bay area, the San Joaquin Valley, the Central Coast, and Southern
California (MET, 2021).
The Delta is key to the SWP's ability to deliver water to its agricultural and urban contractors. All but five
of the 29 SWP contractors receive water deliveries below the Delta (pumped via the Harvey O. Banks or
Barker Slough pumping plants). However, the Delta faces many challenges concerning its long-term
sustainability such as climate change posing a threat of increased variability in floods and droughts.
Sea level rise complicates efforts in managing salinity levels and preserving water quality in the Delta to
ensure a suitable water supply for urban and agricultural use. Furthermore, other challenges include
continued subsidence of Delta islands, many of which are below sea level, and the related threat of a
catastrophic levee failure as the water pressure increases, or as a result of a major seismic event.
Current Conditions and Supply
"Table A"water is the maximum entitlement of SWP water for each water contracting agency. Currently,
the combined maximum Table A amount is 4.17 million AFY. Of this amount, 4.13 million AFY is the
maximum Table A water available for delivery from the Delta. On average, deliveries are approximately
60% of the maximum Table A amount (DWR, 2020b).
SWP contractors may receive Article 21 water on a short-term basis in addition to Table A water if
requested. Article 21 of SWP contracts allows contractors to receive additional water deliveries only
under specific conditions, generally during wet months of the year (December through March). Because a
SWP contractor must have an immediate use for Article 21 supply or a place to store it outside of the
SWP, there are few contractors like MET that can access such supplies.
Carryover water is SWP water allocated to an SWP contractor and approved for delivery to the contractor
in a given year, but not used by the end of the year. The unused water is stored in the SWP's share of
San Luis Reservoir, when space is available, for the contractor to use in the following year.
Turnback pool water is Table A water that has been allocated to SWP contractors that has exceeded their
demands. This water can then be purchased by another contractor depending on its availability.
SWP Delta exports are the water supplies that are transferred directly to SWP contractors or to San Luis
Reservoir storage south of the Delta via the Harvey O. Banks pumping plant. Estimated average annual
Delta exports and SWP Table A water deliveries have generally decreased since 2005, when Delta
export regulations affecting SWP pumping operations became more restrictive due to federal biological
opinions (Biops). The Biops protect species listed as threatened or endangered under the federal and
state Endangered Species Acts (ESAs) and affect the SWP's water delivery capability because they
restrict SWP exports in the Delta and include Delta outflow requirements during certain times of the year,
thus reducing the available supply for export or storage.
Before being updated by the 2019 Long-Term Operations Plan, the prior 2008 and 2009 Biops resulted
in an estimated reduction in SWP deliveries of 0.3 MAF during critically dry years to 1.3 MAF in above
arcadis.com

937
Huntington Beach 2020 Urban Water Management Plan
normal water years as compared to the previous baseline. However, the 2019 Long-Term Operations
Plan and Biops are expected to increase SWP deliveries by an annual average of 20,000 AF as
compared to the previous Biops (MET, 2021). Average Table A deliveries decreased in the
2019 SWP Final Delivery Capability Report compared to 2017, mainly due to the 2018 Coordinated
Operation Agreement (COA)Addendum and the increase in the end of September storage target for
Lake Oroville. Other factors that also affected deliveries included changes in regulations associated with
the Incidental Take Permit (ITP) and the Reinitiation of Consultation for Long-Term Operations (RoC on
LTO), a shift in Table A to Article 21 deliveries which occurred due to higher storage in SWP San Luis,
and other operational updates to the SWP and federal Central Valley Project (CVP) (DWR, 2020b).
Since 2005, there are similar decreasing trends for both the average annual Delta exports and the
average annual Table A deliveries (Table 6-3),

Percent Change' -14.8% -14.3%
Percent change is between the years 2019 and 2005.
Ongoing regulatory restrictions, such as those imposed by the Biops on the effects of SWP and the
CVP operations on certain marine life, also contribute to the challenge of determining the SWP's water
delivery reliability. In dry, below-normal conditions, MET has increased the supplies delivered through the
California Aqueduct by developing flexible CVP/SWP storage and transfer programs. The goal of the
storage/transfer programs is to develop additional dry-year supplies that can be conveyed through the
available Harvey O. Banks pumping plant capacity to maximize deliveries through the California Aqueduct
during dry hydrologic conditions and regulatory restrictions. In addition, the SWRCB has set water quality
objectives that must be met by the SWP including minimum Delta outflows, limits on SWP and CVP Delta
exports, and maximum allowable salinity level.
The following factors affect the ability to estimate existing and future water delivery reliability:
• Water availability at the source: Availability can be highly variable and depends on the amount
and timing of rain and snow that fall in any given year. Generally, during a single-dry year or two,
surface and groundwater storage can supply most water deliveries, but multiple-dry years can
result in critically low water reserves. Fisheries issues can also restrict the operations of the
export pumps even when water supplies are available.
• Water rights with priority over the SWP: Water users with prior water rights are assigned
higher priority in DWR's modeling of the SWP's water delivery reliability, even ahead of SWP
Table A water.
• Climate change: Mean temperatures are predicted to vary more significantly than previously
expected. This change in climate is anticipated to bring warmer winter storms that result in less

6-7
938
Huntington Beach 2020 Urban Water Management Plan
snowfall at lower elevations, reducing total snowpack. From historical data, DWR projects that by
2050, the Sierra snowpack will be reduced from its historical average by 25 to 40 percent.
Increased precipitation as rain could result in a larger number of"rain-on-snow" events, causing
snow to melt earlier in the year and over fewer days than historically, affecting the availability of
water for pumping by the SWP during summer. Furthermore, water quality may be adversely
affected due to the anticipated increase in wildfires. Rising sea levels may result in potential
pumping cutbacks on the SWP and CVP.
• Regulatory restrictions on SWP Delta exports: The Biops protect special-status species such
as delta smelt and spring- and winter-run Chinook salmon and imposed substantial constraints on
Delta water supply operations through requirements for Delta inflow and outflow and export
pumping restrictions. Restrictions on SWP operations imposed by state and federal agencies
contribute substantially to the challenge of accurately determining the SWP's water delivery
reliability in any given year (DWR, 2020b).
• Ongoing environmental and policy planning efforts: Governor Gavin Newsom ended
California WaterFix in May 2019 and announced a new approach to modernize Delta
Conveyance through a single tunnel alternative. The EcoRestore Program aims to restore at least
30,000 acres of Delta habitat, with the near-term goal of making significant strides toward that
objective by 2020 (DWR, 2020b).
• Delta levee failure: The levees are vulnerable to failure because most original levees were
simply built with soils dredged from nearby channels and were not engineered. A breach of
one or more levees and island flooding could affect Delta water quality and SWP operations for
several months. When islands are flooded, DWR may need to drastically decrease or even cease
SWP Delta exports to evaluate damage caused by salinity in the Delta.
Operational constraints will likely continue until a long-term solution to the problems in the Bay-Delta is
identified and implemented. New Biops for listed species under the Federal ESA or by the California
Department of Fish and Game's issuance of incidental take authorizations under the Federal ESA and
California ESA might further adversely affect SWP and CVP operations. Additionally, new litigation,
listings of additional species or new regulatory requirements could further adversely affect
SWP operations in the future by requiring additional export reductions, releases of additional water from
storage or other operational changes impacting water supply operations.
Future Programs I Plans
MET's Board approved a Delta Action Plan in June 2007 that provides a framework for staff to pursue
actions with other agencies and stakeholders to build a sustainable Delta and reduce conflicts between
water supply conveyance and the environment. The Delta Action Plan aims to prioritize immediate
short-term actions to stabilize the Delta while an ultimate solution is selected, and mid-term steps to
maintain the Delta while a long-term solution is implemented. Currently, MET is working towards
addressing four elements: Delta ecosystem restoration, water supply conveyance, flood control
protection, and storage development.
In May 2019, Governor Newsom ended California WaterFix, announced a new approach to modernize
Delta Conveyance through a single tunnel alternative, and released Executive Order 10-19 that directed
state agencies to inventory and assess new planning for the project. DWR then withdrew all project

approvals and permit applications for California WaterFix, effectively ending the project. The purpose of
the Delta Conveyance Project (DCP) gives rise to several project objectives (MET, 2021). In proposing to
make physical improvements to the SWP Delta conveyance system, the project objectives are:
• To address anticipated rising sea levels and other reasonably foreseeable consequences of
climate change and extreme weather events.
• To minimize the potential for public health and safety impacts from reduced quantity and quality
of SWP water deliveries, and potentially CVP water deliveries, south of the Delta resulting from a
major earthquake that causes breaching of Delta levees and the inundation of brackish water into
the areas in which existing pumping plants operate.
To protect the ability of the SWP, and potentially the CVP, to deliver water when hydrologic
conditions result in the availability of sufficient amounts, consistent with the requirements of state
and federal law.
• To provide operational flexibility to improve aquatic conditions in the Delta and better manage
risks of further regulatory constraints on project operations.
6.2.3 Storage
Storage is a major component of MET's dry year resource management strategy. MET's likelihood of
having adequate supply capability to meet projected demands, without implementing its Water Supply
Allocation Plan (WSAP), is dependent on its storage resources. Due to the pattern of generally drier
hydrology, the groundwater basins and local reservoirs have dropped to low operating levels and remain
below healthy storage levels. For example, the Colorado River Basin's system storage at the close of
2020, was at or near its lowest since 2000, so there is very little buffer to avoid a shortage from any future
period of reduced precipitation and runoff(MET, 2021).
MET stores water in both DWR and MET surface water reservoirs. MET's surface water reservoirs are
Lake Mathews, Lake Skinner, and Diamond Valley Lake (DVL), which have a combined storage capacity
of over 1 MAF. Approximately 650,000 AF are stored for seasonal, regulatory, and drought use, while
approximately 370,000 AF are stored for emergency use.
MET also has contractual rights to DWR surface Reservoirs, such as 65 thousand acre-feet (TAF) of
flexible storage at Lake Perris (East Branch terminal reservoir) and 154 TAF of flexible storage at
Castaic Lake (West Branch terminal reservoir) that provides MET with additional options for managing
SWP deliveries to maximize the yield from the project. This storage can provide MET with up to 44 TAF
of additional supply over multiple dry years, or up to 219 TAF to Southern California in a single dry
year (MET, 2021).
MET endeavors to increase the reliability of water supplies through the development of flexible storage
and transfer programs including groundwater storage (MET, 2021). These include:
• Lake Mead Storage Program: Executed in 2006, this program allows MET to leave excessively
conserved water in Lake Mead, for exclusive use by MET in later years. MET created
"Intentionally Created Surplus" (ICS)water in 2006-2007, 2009-2012, and 2016-2019, and
withdrew ICS water in 2008 and 2013-2015. As of January 1, 2021, MET had a total of 1.3 MAF
of Extraordinary Conservation ICS water.
arcadis cam
6-9
940
Huntington Beach 2020 Urban Water Management Plan
• Semitropic Storage Program: The maximum storage capacity of the program is 350 TAF, and
the minimum and maximum annual yields available to MET are 34.7 TAF and 236.2 TAF,
respectively. The specific amount of water MET can expect to store in and subsequently receive
from the program depends on hydrologic conditions, any regulatory requirements restricting
MET's ability to export water for storage and demands placed by other program participants.
During wet years, MET has the discretion to use the program to store portions of its SWP
supplies which are in excess, and during dry years, the Semitropic Water Storage District returns
MET's previously stored water to MET by direct groundwater pump-in or by exchange of surface
water supplies.
• Arvin-Edison Storage Program: The storage program is estimated to deliver 75 TAF, and the
specific amount of water MET can expect to store in and subsequently receive from the program
depends on hydrologic conditions and any regulatory requirements restricting MET's ability to
export water for storage. During wet years, MET has the discretion to use to program to store
portions of its SWP supplies which are in excess, and during dry years, the Arvin-Edison Water
Storage District returns MET's previously stored water to MET by direct groundwater pump-in or
by exchange of surface water supplies.
• Antelope Valley-East Kern (AVEK) Water Agency Exchange and Storage Program: Under
the exchange program, for every two AF MET receives, MET returns 1 AF back to AVEK, and
MET will also be able to store up to 30 TAF in the AVEK's groundwater basin, with a dry-year
return capability of 10 TAF.
• High Desert Water Bank Program: Under this program, MET will have the ability to store up to
280 TAF of its SWP Table A or other supplies in the Antelope Valley groundwater basin, and in
exchange will provide funding for the construction of monitoring and production wells, turnouts
from the California Aqueduct, pipelines, recharge basins, water storage, and booster pump
facilities. The project is anticipated to be in operation by 2025,
• Kern-Delta Water District Storage Program: This groundwater storage program has 250 TAF
of storage capacity, and water for storage can either be directly recharged into the groundwater
basin or delivered to Kern-Delta Water District farmers in lieu of pumping groundwater. During dry
years, the Kern-Delta Water District returns MET's previously stored water to MET by direct
groundwater pump-in return or by exchange of surface water supplies.
• Mojave Storage Program: MET entered into a groundwater banking and exchange transfer
agreement with Mojave Water Agency that allows for the cumulative storage of up to 390 TAF.
The agreement allows for MET to store water in an exchange account for later return.
6.2.4 Planned Future Sources
Beyond the programs highlighted in Sections 6.2.1 through 6.2.3, MET continues to invest in efforts to
meet its goal of long-term regional water supply reliability, focusing on the following:
• Continuing water conservation
• Developing water supply management programs outside of the region
• Developing storage programs related to the Colorado River and the SWP
• Developing storage and groundwater management programs within the Southern California
region
• Increasing water recycling, groundwater recovery, stormwater and seawater desalination

• Pursuing long-term solutions for the ecosystem, regulatory and water supply issues in the
California Bay-Delta (MET, 2021).
6.3 Groundwater
Historically, local groundwater has been the cheapest and most reliable source of supply for the City.
The City draws water from the Basin. Based on the most recent 10-year average, the annual groundwater
volume supplied by the City is 18,871 AFY. In FY 2019-20, the City relied on approximately 18,296 AFY —
approximately 70% of the City's water supply portfolio for FY 2019-20—from the OC Basin to meet its
demands.
This section describes the non-adjudicated OC Basin and the management measures taken by OCWD,
the basin manager to optimize local supply and minimize overdraft. This section also provides information
on historical groundwater production as well as a 25-year projection of the City's groundwater supply.
The OCWD was formed in 1933 by a special legislative act of the California State Legislature to protect
and manage the County's vast, natural, groundwater supply using the best available technology and
defend its water rights to the OC Basin. This legislation is found in the State of California Statutes,
Water— Uncodified Acts, Act 5683, as amended. The OC Basin is managed by OCWD under the Act,
which functions as a statutorily-imposed physical solution. The OCWD Management Area includes
approximately 89% of the land area of the OC Basin, and 98% of all groundwater production occurs
within the area. OCWD monitors the basin by collecting groundwater elevation and quality data from wells
and manages an electronic database that stores water elevation, water quality, production, recharge
and other data on over 2,000 wells and facilities within and outside OCWD boundaries (City of La Habra
et al., 2017).
Groundwater levels are managed within a safe basin operating range to protect the long-term
sustainability of the OC Basin and to protect against land subsidence. OCWD regulates groundwater
levels in the OC Basin by regulating the annual amount of pumping and setting the Basin Production
Percentage (BPP) for the water year. As defined in the District Act, the BPP is the ratio of water produced
from groundwater supplies within the City to all water produced within the City from both supplemental
sources and groundwater within the City (OCWD, 2020).
6.3.1 Historical Groundwater Production
The City draws water from the OC Basin through its eight active groundwater wells. The total potable
water well design capacity is estimated at 25,300 gpm. However, the City does not operate most of its
wells at maximum capacity due to various factors such as lower demand, supporting Basin sustainability,
and also to prolong the life of the wells and their associated supply equipment. Each well is operated only
about six to seven months per year (Psomas, 2016). The City has experienced a relatively steady level of
groundwater production, aside from a decrease in groundwater production in FY 2017-18, when the City
used approximately 9,000 AF of in-lieu water (Table 6-4).

6.3.2 Basin Characteristics
The OC Basin underlies the northerly half of Orange County beneath broad lowlands. The OC Basin,
managed by OCWD, covers an area of approximately 350 square miles, bordered by the Coyote and
Chino Hills to the north, the Santa Ana Mountains to the northeast, and the Pacific Ocean to the
southwest. The OC Basin boundary extends to the Orange County-Los Angeles Line to the northwest,
where groundwater flows across the county line into the Central Groundwater Basin of Los Angeles
County. A map of the OC Basin is shown in Figure 6-2 The total thickness of sedimentary rocks in
the OC Basin is over 20,000 feet, with only the upper 2,000 to 4,000 feet containing fresh water.
The OC Basin's full volume is approximately 66 MAF
There are three major aquifer systems that have been subdivided by OCWD, the Shallow Aquifer System.
the Principal Aquifer System, and the Deep Aquifer System. These three aquifer systems are
hydraulically connected as groundwater is able to flow between each other through intervening aquitards
or discontinuities in the aquitards. The Shallow Aquifer system occurs from the surface to approximately
250 feet below ground surface. Most of the groundwater from this aquifer system is pumped by small
water systems for industrial and agricultural use The Principal Aquifer system occurs at depths between
200 and 1.300 feet below ground surface Over 90% of groundwater production is from wells that are
screened within the Principal Aquifer system. Only a minor amount of groundwater is pumped from the
Deep Aquifer system, which underlies the Principal Aquifer system and is up to 2,000 feet deep in the
center of the OC Basin.
Per- and polyfluoroalkyl substances (PFAS)are a group of thousands of manmade chemicals that

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.
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).
PFAS has not impacted any City wells to date. However, the City routinely monitors and tests for PFAS,
among other contaminants, to ensure a safe and reliable water supply.

6.3.3 Sustainable Groundwater Management Act
In 2014, the State of California adopted the Sustainable Groundwater Management Act (SGMA) to help
manage its groundwater sustainably, and limit adverse effects such as significant groundwater-level
declines, land subsidence, and water quality degradation. SGMA requires all high- and medium-priority
basins, as designated by DWR, be sustainably managed. DWR designated the non-adjudicated Coastal
Plain of the OC Basin ("Basin 8-1" or"Basin") as a medium-priority basin, primarily due to heavy reliance
on the Basin's groundwater as a source of water supply. Compliance with SGMA can be achieved in one
of two ways:
1) A Groundwater Sustainability Agency (GSA) is formed and a Groundwater Sustainability Plan
(GSP) is adopted, or
2) Special Act Districts created by statute, such as OCWD, and other agencies may prepare and
submit an Alternative to a GSP (City of La Habra et al., 2017).
The agencies within Basin 8-1, led by OCWD collaborated to submit an Alternative to a GSP in 2017,
titled the "Basin 8-1 Alternative" to meet SGMA compliance. This document will be updated every
five years. The current (2017)version is included in Appendix G.
6.3.4 Basin Production Percentage
Background
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 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.
Groundwater production at or below the BPP is assessed the Replenishment Assessment (RA).
While there is no legal limit as to how much an agency pumps from the OC Basin, there is a financial
disincentive to pump above the BPP. The BPP is set uniformly for all Producers by OCWD on an annual
basis. Agencies that pump above the BPP are charged the RA plus the Basin Equity Assessment (BEA).
The BEA is presently calculated so that the cost of groundwater production is equivalent to the cost of
importing potable water supplies. This approach serves to discourage, but not eliminate, production
above the BPP, and the BEA can be increased to discourage production above the BPP if necessary.
The BPP is set based on groundwater conditions, availability of imported water supplies, and Basin
management objectives. The supplies available for recharge must be estimated for a given year.
The supplies of recharge water that are estimated are: 1) Santa Ana River stormflow, 2) Natural incidental
recharge, 3) Santa Ana River baseflow, 4) GWRS supplies, and 5) other supplies such as imported water
and recycled water purchased for the Alamitos Barrier. The BPP is a major factor in determining the cost
of groundwater production from the OC Basin for that year. The BPP set for Water Year 2021-22 is 77%.
BPP Adjustments for Basin Management
OCWD has established management guidelines that are used to establish future BPPs, as seen in Table
6-5. Raising or lowering the BPP allows OCWD to manage the amount of pumping from the basin. OCWD
has a policy to manage the groundwater basin within a sustainable range to avoid adverse impacts to the
basin. OCWD seeks to maintain some available storage space in the basin to maximize surface water
arcadts.com
6-15
946
Huntington Beach 2020 Urban Water Management Plan
recharge when such supplies are available, especially in relatively wet years. By keeping the basin
relatively full during wet years, and for as long as possible in years with near-normal recharge, the
maximum amount of groundwater could be maintained in storage to support pumping in future drought
conditions. During dry hydrologic years when less water would be available for recharge, the BPP could
be lowered to maintain groundwater storage levels. A component of OCWD's BPP policy is to manage
the groundwater basin so that the BPP will not fluctuate more that 5% from year to year.
Based on most recent modeling of water supplies available for groundwater recharge and water demand
forecasts, OCWD anticipates being able to sustain the BPP at 85% starting in 2025. The primary reasons
for the higher BPP are the expected completion of the GWRS Final Expansion (GWRSFE) in 2023 and
the relatively low water demands of approximately 400,000 AFY.
Modeling and forecasts generate estimates based on historical averages. Consequently, forecasts use
average hydrologic conditions which smooth the dynamic and unpredictable local hydrology. Variations in
local hydrology are the most significant impact to supplies of water available to recharge the groundwater
basin. The BPP projection of 85% is provided based upon average annual rainfall weather patterns. If the
City were to experience a relatively dry period, the BPP could be reduced to maintain water storage
levels, by as much as five percent.

BPP Exemptions
In some cases, OCWD encourages pumping and treating groundwater that does not meet drinking water
standards in order to protect water quality. This is achieved by using a financial incentive called the
BEA Exemption. A BEA Exemption is used to promote beneficial uses of poor-quality groundwater and
reduce or prevent the spread of poor-quality groundwater into non-degraded aquifer zones. OCWD uses
a partial or total exemption of the BEA to compensate a qualified participating agency or Producer for the
costs of treating poor quality groundwater, which typically include capital, interest and operations and
maintenance costs for treatment facilities. When OCWD authorizes a BEA exemption for a project, it is
obligated to provide the replenishment water for the production above the BPP and forgo the
BEA revenue that OCWD would otherwise receive from the producer (City of La Habra et al., 2017).
Similarly, for proactive water quality management, OCWD exempts a portion of the BEA for their Coastal
Pumping Transfer Program (CPTP). The CPTP encourages inland groundwater producers to increase
pumping and coastal producers like the City to decrease pumping in order to reduce the groundwater

basin drawdown at the coast and protect against seawater intrusion. Inland pumpers can pump above the
BPP without having to pay the full BEA for the amount pumped above the BPP (OCWD, 2015). Coastal
pumpers receive BEA revenue from OCWD to assist in offsetting their additional water supply cost from
taking less groundwater.
6.3.4.1 2020 OCWD Groundwater Reliability Plan
In order to adapt to the substantial growth in water demands in OCWD's management area, it is
paramount to anticipate and understand future water demands and develop projects to increase future
water supplies proactively to match demands. The GRP is a continuation of these planning efforts that
estimates the OC Basin's sustainable average annual production and extrapolates water needs of the OC
Basin by combining recently completed water demand projections and modeling of Santa Ana River flows
available for recharge. These data will be used to evaluate future water supply projects and guide
management of the OC Basin. OCWD is currently developing the GRP, and the first public draft is
expected to be available May 2021,
Current water demand projections show a relatively slow increase over the 25-year planning horizon,
which is generally of similar magnitude as the additional production from the GWRSFE in early 2023.
Once complete, the GWRSFE will increase capacity from 100,000 to 134,000 AFY of high-quality
recycled water. This locally controlled, drought proof supply of water reduces the region's dependance on
imported water.
Historically, the Santa Ana River has served as the primary source of water to recharge the OC Basin.
To determine the availability of future Santa Ana River flows. OCWD utilized surface water flow modeling
of the upper watershed. Modeling was developed to predict the impacts future stormwater capture and
wastewater recycling projects in the upper watershed would have on future Santa Ana River flow rates at
Prado Dam. Santa Ana River base flows are expected to decrease as more water recycling projects are
built in the upper watershed. OCWD continues to work closely with the US Army Corps of Engineers to
temporarily impound and slowly release up to approximately 20,000 AF of stormwater in the Prado Dam
Conservation Pool. To some extent, the losses in baseflow are partially offset through the capture of
additional stormwater held in the Prado Dam Conservation Pool. When available, OCWD will continue to
augment groundwater recharge through the purchase of imported water through MET. OCWD will
diligently monitor and evaluate future water supply projects to sustainably manage and protect the OC
Basin for future generations.
6.3.4.2 OCWD Engineer's Report
The OCWD Engineer's Report reports on the groundwater conditions and investigates information related
to water supply and groundwater basin usage within OCWD's service area.
The overall BPP achieved in the 2019 to 2020 water year within OCWD for non-irrigation use was 75.9%.
The achieved pumping was less than the BPP established for the 2019 to 2020 water year primarily due
to the water quality impacts of PFAS. As indicated in Section 6.3.4, a BPP of 77% was established for
water year 2021-22. Analysis of the groundwater basin's projected accumulated overdraft, the available
supplies to the OC Basin (assuming average hydrology) and the projected pumping demands indicate
that this level of pumping can be sustained for 2021-22 without detriment to the OC Basin (OCWD, 2021).
arcadis com
6-17
948
Huntington Beach 2020 Urban Water Management Plan
In FY 2021-22 additional production of approximately 22,000 AF above the BPP will be undertaken by the
City of Tustin, City of Garden Grove, City of Huntington Beach, Mesa Water District, and IRWD. These
agencies use the additional pumping allowance in order to accommodate groundwater quality
improvement projects. As in prior years, production above the BPP from these projects would be partially
or fully exempt from the BEA as a result of the benefit provided to the OC Basin by removing poor-quality
groundwater and treating it for beneficial use (OCWD, 2021).
6.3.5 Recharge Management
Recharging water into the OC Basin through natural and artificial means is essential to support pumping
from the OC Basin. Active recharge of groundwater began in 1949, in response to increasing drawdown
of the OC Basin and, consequently, the threat of seawater intrusion. The OC Basin's primary source of
recharge is Flow from the Santa Ana River, which is diverted into recharge basins and its main Orange
County tributary, Santiago Creek. Other sources of recharge water include natural infiltration, recycled
water, and imported water. Natural recharge consists of subsurface inflow from local hills and mountains,
infiltration of precipitation and irrigation water, recharge in small Flood control channels, and groundwater
underflow to and from Los Angeles County and the ocean.
Recycled water for the OC Basin recharge is from two sources. The main source of recycled water is from
the GWRS, which is injected into the Talbert Seawater Barrier and recharged in the Kraemer, Miller and
Miraloma Basins (City of La Habra et al., 2017). The second source of recycled water is water purified at
the Water Replenishment District's Leo J. Vander Lans Treatment Facility, which supplies water to the
Alamitos Seawater Barrier (owned and operated by the Los Angeles County Department of Public
Works). OCWD's share of the Alamitos Barrier injection total for water year 2018-19 was less than half of
the total injection, based on barrier wells located within Orange County. The Water Replenishment District
of Southern California (WRD) also works closely with OCWD to ensure that the water demands at the
Alamitos Barrier are fulfilled through the use of recycled water as opposed to imported water, however the
recycled portion was less than 33% for the last six years due to operational issues and wastewater supply
interruptions (OCWD, 2020a). Injection of recycled water into these barriers is an effort by OCWD to
control seawater intrusion into the OC Basin. Operation of the injection wells forms a hydraulic barrier to
seawater intrusion.
OCWD purchases imported water for recharge from MWDOC. Untreated imported water can be used to
recharge the OC Basin through the surface water recharge system in multiple locations, such as Anaheim
Lake, Santa Ana River, Irvine Lake, and San Antonio Creek. Treated imported water can be used for
in -lieu recharge, as was performed extensively from 1977 to 2007 (City of La Habra et al., 2017).
For detailed recharge management efforts from OCWD, refer to OCWD's 2017 "Basin 8-1 Alternative'
(Appendix G).
6.3.6 MET Groundwater Replenishment Program
In the past, OCWD, MWDOC, and MET have coordinated water management to increase storage in the
OC Basin when imported supplies are available for this purpose. MET's groundwater replenishment
program was discontinued on January 1, 2013, and currently MET via MWDOC sells replenishment water
to OCWD at the full service untreated MET rate.
arcadis.com
6-18
949
Huntington Beach 2020 Urban Water Management Plan
MWDOC's imported water sales to OCWD since FY 1990-91 averages approximately 31,200 AF per
year. Recently, due to low Santa Ana River flows as a result of low precipitation and increased use along
the river, OCWD has needed to purchase more imported replenishment water per year than the average
of 31,200 AFY over the last 25 years (this does not include water amounts from MET's Conjunctive Use
Program (CUP) or its Cyclic Storage Account). However, with the emergence of PFAS affecting
groundwater production, the need to purchase imported water has been temporary suspended.
Until PFAS treatment is in place for most groundwater producers in the region, imported replenishment
water will be significantly reduced.
6.3.7 MET Conjunctive Use Program / Cyclic Storage Program with OCWD
Since 2004, OCWD, MWDOC, and certain groundwater producers have participated in MET's CUP.
This program allows for the storage of MET water in the OC Basin. The existing MET program provides
storage up to 66,000 AF of water in the OC Basin to be pumped by participating producers in place of
receiving imported supplies during water shortage events in exchange for MET's contribution to
improvements in basin management facilities and an annual administrative fee. These improvements
include eight new groundwater production wells, improvements to the seawater intrusion barrier, and
construction of the Diemer Bypass Pipeline. The water is accounted for via the CUP program
administered by the wholesale agencies and is controlled by MET such that it can be withdrawn over a
three-year time period (OCWD, 2020). As of 2021, the CUP has not been in use since 2014. The CUP
contract ends in 2028.
The Cyclic Storage account is an alternative storage account with MET. However, unlike the CUP
program, OCWD controls when the water is used. The Cyclic Water Storage Program allows MET to
store water in a local groundwater basin during surplus conditions, where MET has limited space in its
regional storage locations. Once the water is stored via direct delivery or In-lieu the groundwater agency
has the ability to purchase this water at a future date or over a five-year period.
6.3.8 Overdraft Conditions
Annual groundwater basin overdraft, as defined in OCWD's Act, is the quantity by which production of
groundwater supplies exceeds natural replenishment of groundwater supplies during a water year.
This difference between extraction and replenishment can be estimated by determining the change in
volume of groundwater in storage that would have occurred had supplemental water not been used for
any groundwater recharge purpose, including seawater intrusion protection, advanced water reclamation,
and the in-Lieu Program.
The annual analysis of basin storage change and accumulated overdraft for water year 2019-20 has been
completed. Based on the three-layer methodology, an accumulated overdraft of 200,000 AF was
calculated for the water year ending June 30, 2020. The accumulated overdraft for the water year ending
June 30, 2019 was 236,000 AF, which was also calculated using the three-layer storage method.
Therefore, an annual increase of 36,000 AF in stored groundwater was calculated as the difference
between the June 2019 and June 2020 accumulated overdrafts (OCWD, 2021).

6.3.9 Planned Future Sources
The City plans to drill two new wells — Wells 15 and 16—to offset the production lost from abandoned and
reduced-capacity wells. Well treatment at Wells 6 and 6 are also planned to resolve nuisance odor and
color issues that have caused either a reduction in production or temporary shutdown at these wells.
These projects are planned to ensure reliable local groundwater and continued drinking water safety.
These projects are further described in Section 6.9.
On a regional scale, OCWD regularly evaluates potential projects and conducts studies to improve the
existing facilities and build new facilities to include in their Long-Term Facilities Plans (LTFP).
OCWD's 2014 LTFP evaluated 65 potential projects for water supply, basin management, recharge
facilities, operational improvements, and operational efficiency. Some of OCWD's planned water
projects that would increase supply are listed below. For a more detailed list of projects, refer to the
2014 LTFP (OCWD).
• GWRSFE—The Final Expansion of the GWRS is currently underway and is the third and final phase
of the project. When the Final Expansion is completed in early 2023, the plant's treatment capacity
will increase from 100 to 130 MGD. To produce 130 MGD, additional treated wastewater from Orange
County Sanitation District (OC San)'s Treatment Plant 2 is required. This recycled water represents a
high quality, drought-proof source of water to protect and enhance the OC Basin. The Final
Expansion project will include expanding the existing GWRS treatment facilities, constructing new
conveyance facilities at OC San Plant 2, and rehabilitating an existing pipeline between OC San Plant
2 and the GWRS. Once completed, the GWRS plant will recycle 100% of OC San's reclaimable
sources and produce enough water to meet the needs of over one million people.
• Forecast Informed Reservoir Operations (FIRO) at Prado Dam — Stormwater represents a
significant source of water used by OCWD to recharge the OC Basin. Much of this recharge is made
possible by the capture of Santa Ana River stormflows behind Prado Dam in the Conservation Pool.
FIRO represents the next generation of operating water reservoirs using the best available
technology. Advances in weather and stormwater runoff forecasting hold promise to allow USACE to
safety impound more Stormwater while maintaining equivalent flood risk management capability
behind Prado Dam. Preliminary modeling show that by expanding the Conservation Pool from
elevation 505 to 512 ft msl, annual recharge to the groundwater basin could increase by as much as
4,500 to 7,000 AFY.

6.6 Wastewater and Recycled Water
The City is directly involved in wastewater services through its ownership and operation of the wastewater
collection system in its service area. However, the City does not own or operate wastewater treatment
facilities. The City's sewer system includes 360 miles of sewer lines ranging from 6 inches to 30 inches in
diameter, 10,000 manholes and 27 lift stations. The wastewater system serves approximately
200,000 customers.
Recycled water is wastewater that is treated through primary, secondary and tertiary processes and is
acceptable for most non-potable water purposes such as irrigation, and commercial and industrial process
water per Title 22 requirements. Recycled water opportunities have continued to grow in southern
California as public acceptance and the need to expand local water resources continues to be a priority.
Recycled water also provides a degree of flexibility and added reliability during drought conditions when
imported water supplies are restricted. The City is indirectly involved in recycled water production, through
its supply of wastewater for IPR. The following sections expand on the existing agency collaboration
involved in these efforts as well as the City's projected recycled water use over the next 25 years.
6.6.1 Agency Coordination
The City does not own or operate wastewater treatment facilities and sends all collected wastewater to
Orange County Sanitation District (OC San) for treatment and disposal. OC San provides treated water to
OCWD, the manager of the Orange County Groundwater Basin. OCWD strives to maintain and increase
the reliability of the Orange County Groundwater Basin through replenishment with imported water,
stormwater, and advanced treated wastewater. A full description of the Orange County Groundwater
Basin is available in Section 6.3.2. OCWD and OC San have jointly constructed and expanded two
water recycling projects to meet this goal including: 1) OCWD Green Acres Project (GAP), and
2) OCWD GWRS.
6.6.1 .1 OCWD Green Acres Project
OCWD owns and operates the GAP, a water recycling system that provides up to 8,400 AFY of recycled
water for irrigation and industrial uses. GAP provides an alternate source of water that is mainly delivered
to parks, golf courses, greenbelts, cemeteries, and nurseries in the cities of Costa Mesa, Fountain Valley,
Newport Beach, and Santa Ana. Approximately 100 sites use GAP water, current recycled water users
include Mile Square Park and Golf Courses in Fountain Valley, Costa Mesa Country Club, Chroma
Systems carpet dyeing, Kaiser Permanente, and Caltrans, but the City does not receive any GAP water.

6.6.1.2 OCWD Groundwater Replenishment System
OCWD's GWRS allows southern California to decrease its dependency on imported water and creates a
local and reliable source of water. OCWD's GWRS purifies secondary treated wastewater from OC San to
levels that meet and exceed all state and federal drinking water standards. The GWRS Phase 1 plant has
been operational since January 2008 and uses a three-step advanced treatment process consisting of
microfiltration (MF), reverse osmosis (RO), and ultraviolet (UV) light with hydrogen peroxide (H2O2).
A portion of the treated water is injected into the seawater barrier to prevent seawater intrusion into the
groundwater basin. The other portion of the water is pumped to ponds where the water percolates into
deep aquifers and becomes part of Orange County's water supply.
The GWRS first began operating in 2008 producing 70 MGD and in 2015, it underwent a 30 MGD
expansion. Approximately 39,200 AFY of the highly purified water is pumped into the injection wells and
72,900 AFY is pumped to the percolation ponds in the City of Anaheim where the water is naturally
filtered through sand and gravel to deep aquifers of the groundwater basin. The Orange County
Groundwater Basin provides approximately 72% of the potable water supply for north and central Orange
County. The design and construction of the first phase (78,500 AFY) of the GWRS project was jointly
funded by OCWD and OC San; Phase 2 expansion (33,600 AFY)was funded solely by OCWD.
The Final Expansion of the GWRS is currently underway and is the third and final phase of the project.
When the Final Expansion is completed in 2023, the plant will produce 130 MGD. To produce 130 MGD,
additional treated wastewater from OC San is required. This additional water will come from OC San's
Treatment Plant 2, which is in the City of Huntington Beach approximately 3.5 miles south of the GWRS.
The Final Expansion project will include expanding the existing GWRS treatment facilities, constructing
new conveyance facilities at OC San Plant 2 and rehabilitating an existing pipeline between OC San
Plant 2 and the GWRS. Once completed, the GWRS plant will recycle 100% of OC San's reclaimable
sources and produce enough water to meet the needs of over one million people.
6.6.2 Wastewater Description and Disposal
The City operates and maintains the local sewer collection pipes that feed into the OC San's trunk sewer
system to convey wastewater to OC San's treatment plants. OC San has an extensive system of gravity
flow sewers, pump stations, and pressurized sewers. OC San's Plant No. 1 in Fountain Valley has a
capacity of 320 MGD and Plant No. 2 in the City has a capacity of 312 MGD. Both plants share a
common ocean outfall, but Plant No. 1 currently provides all of its secondary treated wastewater to
OCWD's GWRS for beneficial reuse. The 120-inch diameter ocean outfall extends 4 miles off the coast of
the City. A 78-inch diameter emergency outfall also extends 1.3 miles off the coast.
Residential homes northwest of Sunset Beach, in the area known as Surfside, have sewer flow that goes
to the Sunset Beach Sanitary District, which eventually connects into the City's sewer collection system.
The Sunset Aquatic Marina also sends its sewer flow to the City's sewer collection system. Lastly, a
property at the northeast corner of Beach Boulevard and Edinger Avenue is within the City of
Westminster, but their sewage also goes to the City.

6.6.3 Current Recycled Water Uses
There are currently no direct recycled water uses within the City's Retail service area. For indirect use.
the City benefits from OCWD's GWRS system that provides IPR through replenishment of Orange County
Groundwater Basin with water that meets state and federal drinking water standards.
6.6.4 Projected Recycled Water Uses
The City does not have any direct non-potable uses within their service area and does not currently have
the potential for non-potable reuse because of nonexistent or planned recycled water infrastructure.
The City has purple pipe for irrigation of various medians, parkways, and other landscaped areas.
however, has plans to retire this pipe and continue to benefit from OCWD's GWRS system. Although the
2015 UWMP acknowledged IPR of wastewater, it did not quantify projections These projections will be

Studies of water recycling opportunities within southern California provide a context for promoting the
development of water recycling plans. Currently, most of the recycled water available is being directed
toward replenishment of the groundwater basin and improvements in groundwater quality. As a user of

resource for groundwater recharge in Orange County. The City will continue to supply wastewater to
GWRS for IPR.
Public Education
The City participates in the MWDOC public education and school education programs, which include
extensive sections on water recycling. MWDOC's water use efficiency public information programs are a
partnership with agencies throughout the county.
Through a variety of public information programs, MWDOC reaches the public, including those in the City,
with information regarding present and future water supplies, the demands for a suitable quantity and
quality of water, including recycled water, and the importance of implementing water efficiency techniques
and behaviors. Through MWDOC, water education programs have reached thousands of students in the
City with grade-specific programs that include information on recycled water.
Financial Incentives
The implementation of recycled water projects involves a substantial upfront capital investment for
planning studies, Environmental Impact Reports (EIRs), engineering design and construction before there
recycled water is available to the market.
The establishment of new supplemental funding sources through federal, state and regional programs
now provides significant financial incentives for water agencies to develop and make use of recycled
water locally. Potential sources of funding include federal, state and local funding opportunities.
These funding sources include the U.S. Bureau of Reclamation (USBR), California Proposition 13 Water
Bond, Proposition 84, and MET Local Resources Program (LRP). These funding opportunities may be
sought by the City or possibly more appropriately by regional agencies. The City will continue to support
seeking funding for regional water recycling projects and programs.
Optimization Plan
The City does not use recycled water, therefore, there is no need for a recycled water optimization plan.
In other areas of Orange County, recycled water is used for irrigating golf courses, parks, schools,
businesses, and communal landscaping, as well as for groundwater recharge. Analyses have indicated
that present worth costs to incorporate recycled water within the City are not cost effective as compared
to purchasing imported water from MWDOC or using groundwater. The City will continue to conduct
feasibility studies for recycled water and seek out creative solutions such as funding, regulatory
requirements, institutional arrangement, and public acceptance for recycled water use with MWDOC,
OCWD, MET, and other cooperative agencies.
6.7 Desalination Opportunities
In 2001, MET developed a Seawater Desalination Program (SDP) to provide incentives for developing
new seawater desalination projects in MET's service area. In 2014, MET modified the provisions of their
LRP to include incentives for locally produced seawater desalination projects that reduce the need for
imported supplies. To qualify for the incentive, proposed projects must replace an existing demand or
prevent new demand on MET's imported water supplies. In return, MET offers three incentive formulas
under the program:
arcades com
6-27
958
Huntington Beach 2020 Urban Water Management Plan
• Sliding scale incentive up to $340 per AF for a 25-year agreement term, depending on the unit
cost of seawater produced compared to the cost of MET supplies.
• Sliding scale incentive up to S475 per AF for a 15-year agreement term, depending on the unit
cost of seawater produced compared to the cost of MET supplies.
• Fixed incentive up to $305 per AF for a 25-year agreement term.
Developing local supplies within MET's service area is part of their IRP goal of improving water supply
reliability in the region. Creating new local supplies reduce pressure on imported supplies from the
SWP and Colorado River.
On May 6th, 2015, the SWRCB approved an amendment to the state's Water Quality Control Plan for the
Ocean Waters of California (California Ocean Plan) to address effects associated with the construction
and operation of seawater desalination facilities (Desalination Amendment). The amendment supports the
use of ocean water as a reliable supplement to traditional water supplies while protecting marine life and
water quality. The California Ocean Plan now formally acknowledges seawater desalination as a
beneficial use of the Pacific Ocean and the Desalination Amendment provides a uniform, consistent
process for permitting seawater desalination facilities statewide.
If the following projects are developed, MET's imported water deliveries to Orange County could be
reduced. These projects include the Huntington Beach Seawater Desalination Project and the Doheny
Desalination Project.
As for City-led initiatives, the City has not investigated seawater desalination as a result of economic and
physical impediments.
Brackish groundwater is groundwater with a salinity higher than freshwater, but lower than seawater.
Brackish groundwater typically requires treatment using desalters.
6.7.1 Ocean Water Desalination
Huntington Beach Seawater Desalination Project— Poseidon Resources LLC (Poseidon), a private
company, is developing the Huntington Beach Seawater Desalination Project to be co-located at the
AES Power Plant in the City of Huntington Beach along Pacific Coast Highway and Newland Street.
The proposed project would produce up to 50 MGD (56,000 AFY) of drinking water to provide
approximately 10% of Orange County's water supply needs.
Over the past several years, Poseidon has been working with OCWD on the general terms and conditions
for selling the water to OCWD. OCWD and MWDOC have proposed a few distribution options to agencies
in Orange County. The northern option proposes the water be distributed to the northern agencies closer
to the plant within OCWD's service area with the possibility of recharging/injecting a portion of the product
water into the OC Basin. The southern option builds on the northern option by delivering a portion of the
product water through the existing OC-44 pipeline for conveyance to the South Orange County water
agencies. A third option is also being explored, which includes all of the product water to be recharged
into the OC Basin. Currently, a combination of these options could be pursued.
The Huntington Beach Seawater Desalination project plant capacity of 56,000 AFY would be the single
largest source of new, local drinking water available to the region. In addition to offsetting imported
arcadis con)
6-28
959
Huntington Beach 2020 Urban Water Management Plan
demand, water from this project could provide OCWD with management flexibility in the OC Basin by
augmenting supplies into the Talbert Seawater Barrier to prevent seawater intrusion.
In May 2015, OCWD and Poseidon entered into a non-binding Term Sheet that provided the overall
partner structure in order to advance the project. Based on the initial Term Sheet, which was updated in
2018, Poseidon would be responsible for permitting, financing, design, construction, and operations of the
treatment plant while OCWD would purchase the production volume, assuming the product water quality
and quantity meet specific contract parameters and criteria. Furthermore, OCWD would then distribute
the water in Orange County using one of the proposed distribution options described above.
Currently, the project is in the regulatory permit approval process with the Regional Water Quality Control
Board and the California Coastal Commission. Once all of the required permits are approved, Poseidon
will then work with OCWD and interested member agencies in developing a plan to distribute the water.
Subsequent to the regulatory permit approval process, and agreement with interested parties, Poseidon
estimates that the project could be online as early as 2027.
Under guidance provided by DWR, the Huntington Beach Seawater Desalination Plant's projected water
supplies are not included in the supply projections due to its current status within the criteria established
by State guidelines (DWR, 2020c).
Doheny Desalination Project— South Coast Water District (SCWD) is proposing to develop an ocean
water desalination facility in Dana Point. SCWD intends to construct a facility with an initial capacity of up
to 5 million gallons per day (MGD). The initial up to 5 MGD capacity would be available for SCWD and
potential partnering water agencies to provide a high quality, locally-controlled, drought-proof water
supply. The desalination facility would also provide emergency backup water supplies, should an
earthquake, system shutdown, or other event disrupt the delivery of imported water to the area. The
Project would consist of a subsurface slant well intake system (constructed within Doheny Beach Slate
Park), raw (sea) water conveyance to the desalination facility site (located on SCWD owned property), a
seawater reverse osmosis (SWRO) desalination facility, brine disposal through an existing wastewater
ocean outfall, solids handling facilities, storage, and potable water conveyance interties to adjacent local
and regional distribution infrastructure.
The Doheny Ocean Desalination Project has been determined as the best water supply option to meet
reliability needs of SCWD and south Orange County. SCWD is pursuing the Project to ensure it meets
the water use needs of its customers and the region by providing a drought-proof potable water supply,
which diversifies SCWD's supply portfolio and protects against long-term imported water emergency
outages and supply shortfalls that could have significant impact to our coastal communities, public health,
and local economy. Phase I of the Project (aka, the "Local" Project) will provide SCWD and the region
with up to 5 MGD of critical potable water supply that, together with recycled water, groundwater, and
conservation, will provide the majority of SCWD's water supply through local reliable sources. An up to
15 MGD capacity project has been identified as a potential future "regional" project that could be phased
incrementally, depending on regional needs.
On June 27, 2019, SCWD certified the final EIR and approved the Project. The Final EIR included
considerable additional information provided at the request of the Coastal Commission and the Regional
Board, including an updated coastal hazard analysis, updated brine discharge modeling, and updated
groundwater modeling, updated hydrology analysis. The approval of the Project also included a
2M26s com

960
Huntington Beach 2020 Urban Water Management Plan
commitment to 100 percent carbon neutrality through a 100 percent offset of emissions through the
expansion of Project mitigation and use of renewable energy sources. SCWD is currently in the
permitting process and finalizing additional due diligence studies. If implemented, SCWD anticipates an
online date of 2025.
Under guidance provided by DWR, the Doheny Seawater Desalination Project's projected water supplies
are not included in the supply projections due to its current status within the criteria established by State
guidelines (DWR, 2020c).
6.7.2 Groundwater Desalination
There are currently no brackish groundwater opportunities within the City's service area.
6.8 Water Exchanges and Transfers
Interconnections with other agencies result in the ability to share water supplies during short term
emergency situations or planned shutdowns of major imported water systems. However, beyond
short -term outages, transfers can also be involved with longer term water exchanges to deal with
droughts or water allocation situations. The following subsections describe the City's existing and planned
exchanges and transfers.
6.8.1 Existing Exchanges and Transfers
The City maintains three connections with MET transmission mains as follows:
• OC-9 (northeast side of City)
• OC-35 (northwest side of City)
• OC-44 (southeast side of City)
Interconnections with other agencies result in the ability to share water supplies during short term
emergency situations or planned shutdowns of major imported systems. The City maintains
five emergency connections with adjacent water agencies as follows:
• By Anderson Street and PCH (with Golden State Water Company)
• On PCH, north of Sea Way (with Golden State Water Company)
• On Garfield Avenue, east of Bushard Street (with City of Fountain Valley)
• On Sugar Drive, east of Rushmoor Lane (with City of Westminster)
• On Heil Ave, west of Newland (with City of Westminster)
6.8.2 Planned and Potential Exchanges and Transfers
The City does not currently have plans to introduce new exchanges and transfers. However,
MWDOC continues to help its retail agencies develop transfer and exchange opportunities that promote
reliability within their systems. Therefore, MWDOC will look to help its retail agencies navigate the
operational and administrative issues of transfers within the MET distribution system.
In an indirect regional scale, the Santa Ana River Conservation and Conjunctive Use Project (SARCCUP)
is a joint project established by five regional water agencies within the Santa Ana River Watershed
arcadis corn
6-30
961
Huntington Beach 2020 Urban Water Management Plan
(Eastern Municipal Water District, Inland Empire Utilities Agency, Western Municipal Water District,
OCWD, and San Bernardino Valley Municipal Water District).
In 2016, SARCCUP was successful in receiving $55 million in grant funds from Proposition 84 through
DWR. The overall SARCCUP program awarded by Proposition 84, consists of three main program
elements:
• Watershed-Scale Cooperative Water Banking Program
• Water Use Efficiency: Landscape Design and Irrigation Improvements and Water Budget
Assistance for Agencies
• Habitat Creation and Arundo Donax Removal from the Santa Ana River
The Watershed-Scale Cooperative Water Banking Program is the largest component of SARCCUP and
since 2016, Valley, MET, and the four SARCCUP-MWD Member Agencies, with MWDOC representing
OCWD, have been discussing terms and conditions for the ability to purchase surplus water from Valley
to be stored in the Santa Ana River watershed. With the Valley and MET surplus water purchase
agreement due for renewal, it was the desire of Valley to establish a new agreement with MET that allows
a portion of its surplus water to be stored within the Santa Ana River watershed.
An agreement between MET and four SARCCUP-MWD Member Agencies was approved earlier this year
that gives the SARCCUP agencies the ability to purchase a portion (up to 50%) of the surplus water that
San Bernardino Valley Municipal Water District (Valley), a SWP Contractor, sells to MET. Such water will
be stored in local groundwater basins throughout the Santa Ana River watershed and extract during dry
years to reduce the impacts from multiyear droughts. In Orange County, 36,000 AF can be stored in the
OC Basin for use during dry years. More importantly, this stored SARCCUP water can be categorized as
"extraordinary supplies", if used during a MET allocation, and can enhance a participating agencies'
reliability during a drought. Moreover, if excess water is available MWDOC can purchase additional water
for its service area.
Further details remain to be developed between OCWD, retail agencies, and MWDOC in how the water
will be distributed in Orange County and who participates.
6.9 Summary of Future Water Supply Projects
The City continually reviews practices that will provide its customers with adequate and reliable supplies.
Trained staff continue to ensure the water quality is safe and the water supply will meet present and
future needs in an environmentally and economically responsible manner.
Although the City has numerous projects planned to maintain and improve the water system
(Section 6.9.1), there are currently no City-specific planned projects that have both a concrete timeline
and a quantifiable increase in supply.
6.9.1 City Initiatives
The City anticipates water demand in the City to remain relatively constant over the next 25 years due to
minimal growth combined with WUE measures and the increased use of recycled water. Any new water
supply sources will be developed primarily to better manage the Basin and to replace or upgrade
inefficient wells, rather than to support population growth and new development.
arcadis con)
6-31
962
Huntington Beach 2020 Urban Water Management Plan
The projects that have been identified by the City to improve the City's water supply reliability and
enhance the operations of the City include replacement of water meters, fire hydrants, and electrical
equipment; seismic modifications on reservoirs; water security improvements, and improvement projects
on water supply wells. The projects identified in the City's 2016 Water Master Plan Update and Capital
Improvement Program include the below. For the full list of projects, refer to the City's Water Master Plan
Update (Psomas, 2016).
Water Distribution System Improvements — These projects aim to install new distribution mains and
infrastructure to optimize system redundancy, efficiency, and reliability. This includes aging pipe
replacement, the Southeast Reservoir transmission main construction, and fire protection improvements.
Water Production System Improvements— Improvements are planned at various production facilities,
including new and existing wells, reservoirs, and booster stations. This includes permanent wellhead
facilities for Well No. 13 and the Southeast Reservoir and Booster Pump Station.
New Well 15 -A new well with a projected design capacity of around 1,500 to 2,000 gpm will be installed
by Edwards Street in the Ex-NAVY Easement Right-of-Way. This project would help offset the well
capacity reductions from the existing eight active wells.
New Well 16 — A new well with a projected design capacity of around 1,500 to 2,000 gpm will be installed
by Goldenwest Street in the Ex-NAVY Easement Right-of-Way. This project would help offset the well
capacity reductions from the existing eight active wells.
Well Site No. 6 and 8 Treatment—Although the existing well infrastructures are in good condition, the
production rate of various wells have been reduced by at least 50% because of customer complaints.
Treatment implementation projects are included in the City's CIP.
• Well No. 6: This 3,000 gpm pump design capacity well has been out of service due to customer
complains of odor from presence of Hydrogen Sulfide and color in the water. Studies and an
eventual treatment will be necessary to return the well to produce high quality water at full design
capacity.
• Well No. 8: This 3,000 gpm pump design capacity well has been out of service due to customer
complains of odor from presence of Hydrogen Sulfide and color in the water. Studies and an
eventual treatment will be necessary to return the well to produce high quality water at full design
capacity.
6.9.2 Regional Initiatives
Beyond City-specific projects, the City consistently coordinates its long-term water shortage planning with
MWDOC and OCWD. MWDOC has identified the following future regional projects, some of which can
indirectly benefit the City to further increase local supplies and offset imported supplies (CDM Smith, 2019):
Poseidon Huntington Beach Ocean Desalination Project— Poseidon Resources LLC proposes to
construct and operate the Huntington Beach Ocean Desalination Plant on a 12-acre parcel adjacent to
the AES Huntington Beach Generating Station. The facility would have a capacity of 50 MGD and
56,000 AFY, with its main components consisting of a water intake system, a desalination facility, a
concentrate disposal system, and a product water storage tank. This project would provide both system

and supply reliability benefits to the South Orange County (SOC), the OC Basin, and Huntington Beach.
The capital cost in the initial year for the plant is $1.22 billion.
Doheny Ocean Desalination Project— SCWD is proposing to construct an ocean water desalination
facility in Dana Point at Doheny State Beach. The facility would have an initial up to 5 MGD capacity, with
the potential for future expansions up to 15 MGD. The project's main components are a subsurface water
intake system, a raw ocean water conveyance pipeline, a desalination facility, a seawater reverse
osmosis (SWRO) desalination facility, a brine disposal system, and a product water storage tank.
San Juan Watershed Project— Santa Margarita Water District (SMWD) and other project partners have
proposed a multi-phased project within the San Juan Creek Watershed to capture local stormwater and
develop, convey, and recharge recycled water into the San Juan Groundwater Basin and treat the water
upon pumping it out of the basin. The first phase includes the installation of three rubber dams within
San Juan Creek to promote in-stream recharge of the basin, with an anticipated production of 700 AFY
on average. The second phase would develop additional surface water and groundwater management
practices by using stormwater and introducing recycled water for infiltration into the basin and has an
anticipated production of 2,660 to 4,920 AFY. The third phase will introduce recycled water directly into
San Juan Creek through live stream recharge, with an anticipated production of up to 2,660 AFY (SMWD,
2021).
Cadiz Water Bank — SMWD and Cadiz, Inc. are developing this project to create a new water supply by
conserving groundwater that is currently being lost to evaporation and recovering the conserved water by
pumping it out of the Fenner Valley Groundwater Basin to convey to MET's CRA. The project consists of
a groundwater pumping component that includes an average of 50 TAFY of groundwater that can be
pumped from the basin over a 50-year period, and a water storage component that allows participants to
send surplus water supplies to be recharged in spreading basins and held in storage.
South Orange County Emergency Interconnection Expansion — MWDOC has been working with the
SOC agencies on improvements for system reliability primarily due to the risk of earthquakes causing
outages of the MET imported water system as well as extended grid outages. Existing regional
interconnection agreements between IRWD and SOC agencies provides for the delivery of water through
the IRWWD system to participating SOC agencies in times of emergency. MWDOC and IRWD are
currently studying an expansion of the program, including the potential East Orange County Feeder No. 2
pipeline and an expanded and scalable emergency groundwater program, with a capital cost of$867,451.
SARCCUP— SARCCUP is a joint project established between MET, MWDOC, Eastern MWD, Western
MWD, Inland Empire Utilities Agency, and OCWD that can provide significant benefits in the form of
additional supplies during dry years for Orange County. Surplus SWP water from San Bernardino Valley
Water District (SBVMWD) can be purchased and stored for use during dry years. This water can even be
considered an extraordinary supply under MET allocation Plan, if qualified under MET's extraordinary
supply guidelines. OCWD has the ability to store 36,000 AF of SARCCUP water and if excess water is
available MWDOC has the ability to purchase additional water. Further details remain to be developed
between OCWD, retail agencies, and MWDOC in how the water will be distributed in Orange County and
who participates.
Moulton Niquel Water District (MNWD) /OCWD Pilot Storage Program - OCWD entered into an
agreement with MNWD to develop a pilot program to explore the opportunity to store water in the OC
arcadis com
6-33
964
Huntington Beach 2020 Urban Water Management Plan
Basin. The purpose of such a storage account would provide MNWD water during emergencies and/or
provide additional water during dry periods. As part of the agreement, OCWD hired consultants to
evaluate where and how to extract groundwater from the OC Basin with several options to pump the
water to MNWD via the East Orange County Feeder No. 2; as well as a review of existing
banking/exchange programs in California to determine what compensation methodologies could OCWD
assess for a storage/banking program.
6.10 Energy Intensity
A new requirement for this 2020 UWMP is an energy intensity analysis of the Supplier's water,
wastewater, and recycled water systems, where applicable for a 12-month period. The City owns and
operates a water distribution system and a wastewater collection system but no treatment systems. This
section reports the energy intensity for each system using data from FY2019. The recycled water system
within the City is owned and operated by OCWD, therefore it is outside of the City's operational control.
Water and energy resources are inextricably connected. Known as the "water-energy nexus", the
California Energy Commission estimates the transport and treatment of water, treatment and disposal of
wastewater, and the energy used to heat and consume water account for nearly 20% of the total
electricity and 30% of non-power plant related natural gas consumed in California. In 2015, California
issued new rules requiring 50% of its power to come from renewables, along with a reduction in
greenhouse gas (GHG) emissions to 40% below 1990 levels by 2030. Consistent with energy and water
conservation, renewable energy production, and GHG mitigation initiatives, the City reports the energy
intensity of its water and wastewater operations.
The methodology for calculating water energy intensity outlined in Appendix O of the UWMP Guidebook
was adapted from the California Institute for Energy Efficiency exploratory research study titled
"Methodology for Analysis of the Energy Intensity of California's Water Systems" (Wilkinson 2000).
The study defines water energy intensity as the total amount of energy, calculated on a whole-system
basis, required for the use of a given amount of water in a specific location.
UWMP reporting is limited to available energy intensity information associated with water processes
occurring within an urban water supplier's direct operational control. Operational control is defined as
authority over normal business operations at the operational level. Any energy embedded in water
supplies imparted by an upstream water supplier (e.g.. water wholesaler) or consequently by a
downstream water purveyor (e.g., retail water provider) is not included in the UWMP energy intensity
tables. The City's calculations conform to methodologies outlined in the UWMP Guidebook and Wilkinson
study.
Although the standard reporting cycle for GHG emissions is calendar years, the data that follows is for the
12 month period from July 2019 to June 2020 which was the most up-to-date data at the time this report
was written.
6.10.1 Water Supply Energy Intensity
In FY 2019-20, the City consumed 912 kilowatt-hours (KWh) per AF for water services (Table 6-9).
The basis for calculations is provided in more detail in the following subsections.

6.10.1 .1 Operational Control and Reporting Board
As described throughout the report, the City is a retail agency that relies on groundwater and imported
water. The City does not treat water that it distributes.
Water supply energy intensity was calculated for FY 2019-20. Calendar year reporting is standard for
energy and GHG reporting to the Climate Registry, California Air Resources Board, and the United States
Environmental Protection Agency because it provides consistency when assessing direct and indirect
energy consumption within a larger geographical context, versus fiscal year starting dates which can vary
between utilities and organizations. However, fiscal year data was used for this report because it was the
most recent data available.
6.10.1 .2 Volume of Water Entering Processes
According to well meters, the City extracted 18,577 AF of groundwater from the OC Basin and distributed
29,287 AF of both groundwater and imported water. Water distribution volume is based on
MWDOC records.
6.10.1.3 Energy Consumption and Generation
According to Southern California Edison Electricity Bills, groundwater wells consumed 22,414,962 kWh of
electricity and pump stations along the distribution system consumed 4,301,906 kWh of electricity.
Wells and pump stations use a combination of electricity and natural gas but for this report, all natural gas
usage was converted to kWh equivalent. Currently, the City does not generate renewable energy.
Energy consumption is based on metered data.
6.10.2 Wastewater and Recycled Water Energy Intensity
In FY 2019-20, the City consumed 40 KWh per AF for wastewater services (Table 6-10). The basis for
calculations is provided in more detail in the following subsections.

6.10.2.1 Operational Control and Reporting Board
The City's existing sewer system is made up of a network of gravity sewers and 27 lift stations.
As explained in Section 6.6, the City owns and operates wastewater lift stations but no treatment facilities.
Similar to the water supply energy intensity, wastewater energy intensity was calculated for FY 2019-20.
6.10.2.2 Volume of Wastewater Entering Processes
In CY 2019, the City collected and conveyed 19,037 AF of wastewater to OC San. The City does not
provide any wastewater treatment or operate any part of the recycled water system within the City.
6.10.2.3 Energy Consumption and Generation
According to Southern California Edison Electricity Bills, the City's 27 wastewater lift stations consumed
760,742 kWh of electricity. There are no other wastewater facilities that are owned and operated by the
City. Currently, the City does not generate renewable energy. Energy consumption data was based on
metered data from SCE.
6.10.3 Key Findings and Next Steps
Calculating and disclosing direct operationally-controlled energy intensities is another step towards
understanding the water-energy nexus. However, much work is still needed to better understand
upstream and downstream (indirect)water-energy impacts. When assessing water supply energy
intensities or comparing intensities between Suppliers, it is important to consider reporting boundaries as
they do not convey the upstream embedded energy or impacts energy intensity has on downstream
users. Engaging one's upstream and downstream supply chain can guide more informed decisions that
holistically benefit the environment and are mutually beneficial to engaged parties. Suggestions for further
study include:
• Supply-chain engagement — The City relies on a variety of water sources for their customers.
While some studies have used life cycle assessment tools to estimate energy intensities, there is
a need to confirm this data. The 2020 UWMP requirement for all agencies to calculate energy
intensity will help the City and neighboring agencies make more informed decisions that would
benefit the region as a whole regarding the energy and water nexus. A similar analysis could be
performed with upstream supply chain energy, for example, with State Project Water.
• Internal benchmarking and goal setting —With a focus on energy conservation and a projected
increase in water demand despite energy conservation efforts, the City's energy intensities will
likely decrease with time. Conceivably, in a case where water demand decreases, energy
intensities may rise as the energy required to pump or treat is not always proportional to water
delivered. In the course of exploring the water-energy nexus and pursuing renewable energy
goals, there is a need to assess whether energy intensity is a meaningful indicator or if it makes
sense to use a different indicator to reflect the City's commitment to energy and water
conservation.

• Regional sustainability—Water and energy efficiency are two components of a sustainable future.
Efforts to conserve water and energy, however, may impact the social, environmental, and
economic livelihood of the region. In addition to the relationship between water and energy, over
time, it may also be important to consider and assess the connection these resources have on
other aspects of a sustainable future.
• Consistent reporting —as discussed in this report, GHG's are typically reported on a calendar
year cycle but this report used financial year data. In the future, Huntington Beach should
consider evaluating calendar year energy intensities for better benchmarking and consistency
with other agencies.

7 WATER SERVICE RELIABILITY AND DROUGHT RISK
ASSESSMENT
Building upon the water supply identified and projected in Section 6, this key section of the
UWMP examines the City's projected water supplies, water demand, and the resulting water supply
reliability. Water service reliability reflects the City's ability to meet the water needs of its customers under
varying conditions. For the UWMP, water supply reliability is evaluated in two assessments: 1) the Water
Service Reliability Assessment and 2) the DRA. The Water Service reliability assessment compares
projected supply to projected demand in 2025 through 2045 for three hydrological conditions: a normal
year, a single dry year, and a drought period lasting five consecutive years. The DRA, a new UWMP
requirement, assesses near-term water supply reliability. It compares projected water supply and demand
assuming the City experiences a drought period for the next five consecutive years. Factors affecting
reliability, such as climate change and regulatory impacts, are accounted for in the assessment.
7.1 Water Service Reliability Overview
Every urban water supplier is required to assess the reliability of their water service to their customers
under normal, single-dry, and multiple dry water years. 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. Development of local supplies augments the reliability of the water system. There are various
factors that may impact reliability of supplies such as legal, environmental, water quality and climatic
which are discussed below. MET's and MWDOC's 2020 UWMPs conclude that they can meet full-service
demands of their member agencies starting 2025 through 2045 during normal years, a single-dry year,
and multiple-dry years. Consequently, the City is projected to meet full-service demands through 2045 for
the same scenarios.
MET's 2020 IRP update describes the core water resources that will be used to meet full-service
demands at the retail level under all foreseeable hydrologic conditions from 2025 through 2045.
The foundation of MET's resource strategy for achieving regional water supply reliability has been to
develop and implement water resources programs and activities through its IRP preferred resource mix.
This preferred resource mix includes conservation, local resources such as water recycling and
groundwater recovery, Colorado River supplies and transfers, SWP supplies and transfers, in-region
surface reservoir storage, in-region groundwater storage, out-of-region banking, treatment, conveyance,
and infrastructure improvements.
Table 7-1 shows the basis of water year data used to predict drought supply availability. The average
(normal) hydrologic condition for the MWDOC service area, which the City is a part of, is represented by
FY 2017-18 and FY 2018-19 and the single-dry year hydrologic condition by FY 2013-14. The five
consecutive years of FY 2011-12 to FY 2015-16 represent the driest five consecutive year historic
sequence for MWDOC's service area. Locally, Orange County rainfall for the five-year period totaled
36 inches, the driest on record.

with imported water from MWDOC/ MET(on top of local groundwater), the percent of average supply
value reported is equivalent to the percent of average demand under the corresponding hydrologic
condition.

The following sections provide a detailed discussion of the City's water source reliability. Additionally, the
following sections compare the City's projected supply and demand under various hydrological
conditions, to determine the City's supply reliability for the 25-year planning horizon.
7.2 Factors Affecting Reliability
In order to prepare realistic water supply reliability assessments, various factors affecting reliability were
considered. These include climate change and environmental requirements, regulatory changes, water
quality impacts, and locally applicable criteria.
7.2.1 Climate Change and the Environment
Changing climate patterns are expected to shift precipitation patterns and affect water supply availability.
Unpredictable weather patterns will make water supply planning more challenging. Although climate
change impacts are associated with exact timing, magnitude, and regional impacts of these temperature
and precipitation changes, researchers have identified several areas of concern for California water
planners (MET, 2021). These areas include:
• A reduction in Sierra Nevada Mountain snowpack.
• Increased intensity and frequency of extreme weather events.
• Prolonged drought periods.
• Water quality issues associated with increase in wildfires.
• Changes in runoff pattern and amount.
• Rising sea levels resulting in:
o Impacts to coastal groundwater basins due to seawater intrusion.
o Increased risk of damage from storms, high-tide events, and the erosion of levees.
o Potential pumping cutbacks to the SWP and CVP.
Other important issues of concern due to global climate change include:
• Effects on local supplies such as groundwater.
• Changes in urban and agricultural demand levels and patterns.
• Increased evapotranspiration from higher temperatures.
• Impacts to human health from water-borne pathogens and water quality degradation.
• Declines in ecosystem health and function.
• Alterations to power generation and pumping regime.
• Increases in ocean algal blooms affected seawater desalination supplies.
The major impact in California is that without additional surface storage, the earlier and heavier runoff
(rather than snowpack retaining water in storage in the mountains), will result in more water being lost to
the oceans. A heavy emphasis on storage is needed in California.
In addition, the Colorado River Basin supplies have been inconsistent since about the year 2000, with
precipitation near normal while runoff has been less than average in two out of every three years.
Climate models are predicting a continuation of this pattern whereby hotter and drier weather conditions
will result in continuing lower runoff, pushing the system toward a drying trend that is often characterized
as long term drought.

Huntington Beach 2020 Urban Water Management Plan
Dramatic swings in annual hydrologic conditions have impacted water supplies available from the
SWP over the last decade. The declining ecosystem in the Delta has also led to a reduction in water
supply deliveries, and operational constraints, which will likely continue until a long-term solution to these
problems is identified and implemented (MET, 2021).
Legal, environmental, and water quality issues may have impacts on MET supplies. It is felt, however,
that climatic factors would have more of an impact than legal, water quality, and environmental factors.
Climatic conditions have been projected based on historical patterns, but severe pattern changes are still
a possibility in the future (MET, 2021).
7.2.2 Regulatory and Legal
Ongoing regulatory restrictions, such as those imposed by the Biops on the effects of SWP and the
federal CVP operations on certain marine life, also contributes to the challenge of determining water
delivery reliability. Endangered species protection and conveyance needs in the Delta have resulted in
operational constraints that are particularly important because pumping restrictions impact many water
resources programs —SWP supplies and additional voluntary transfers, Central Valley storage and
transfers, and in-region groundwater and surface water storage. Biops protect special-status species
listed as threatened or endangered under the ESAs and imposed substantial constraints on Delta water
supply operations through requirements for Delta inflow and outflow and export pumping restrictions.
In addition, the SWRCB has set water quality objectives that must be met by the SWP including minimum
Delta outflows, limits on SWP and CVP Delta exports, and maximum allowable salinity level. SWRCB
plans to fully implement the new Lower San Joaquin River (LSJR) flow objectives from the Phase 1 Delta
Plan amendments through adjudicatory (water rights) and regulatory (water quality) processes by 2022.
These LSJR flow objectives are estimated to reduce water available for human consumptive use.
New litigation, listings of additional species under the ESAs, or regulatory requirements imposed by the
SWRCB could further adversely affect SWP operations in the future by requiring additional export
reductions, releases of additional water from storage, or other operational changes impacting water
supply operations.
The difficulty and implications of environmental review, documentation, and permitting pose challenges
for multi-year transfer agreements, recycled water projects, and seawater desalination plants.
The timeline and roadmap for getting a permit for recycled water projects are challenging and
inconsistently implemented in different regions of the state. IPR projects face regulatory restraints such as
treatment, blend water, retention time, and Basin Plan Objectives, which may limit how much recycled
water can feasibly be recharged into the groundwater basins. New regulations and permitting uncertainty
are also barriers to seawater desalination supplies, including updated Ocean Plan Regulations, Marine
Life Protected Areas, and Once-Through Cooling Regulations (MET, 2021).
7.2.3 Water Quality
The following sub-sections include narratives on water quality issues experienced in various water
supplies, if any, and the measures being taken to improve the water quality of these sources.
arcadis.com
7-4
974
Huntington Beach 2020 Urban Water Management Plan
7.2.3.1 Imported Water
MET is responsible for providing high quality potable water throughout its service area. Over
300,000 water quality tests are performed per year on MET's water to test for regulated contaminants and
additional contaminants of concern to ensure the safety of its waters. MET's supplies originate primarily
from the CRA and from the SWP. A blend of these two sources, proportional to each year's availability of
the source, is then delivered throughout MET's service area.
MET's primary water sources face individual water quality issues of concern. The CRA water source
contains higher total dissolved solids (TDS) and the SWP contains higher levels of organic matter,
lending to the formation of disinfection byproducts. To remediate the CRA's high level of salinity and the
SWP's high level of organic matter, MET blends CRA and SWP supplies and has upgraded all of its
treatment facilities to include ozone treatment processes. In addition, MET has been engaged in efforts to
protect its Colorado River supplies from threats of uranium, perchlorate, and chromium VI while also
investigating the potential water quality impact of the following emerging contaminants: N-
nitrosodimethylamine (NDMA), pharmaceuticals and personal care products (PPCP), microplastics,
per- and polyfluoroalkyl substances (PFAS), and 1,4-dioxane (MET, 2021). While unforeseeable water
quality issues could alter reliability, MET's current strategies ensure the delivery of high-quality water.
The presence of quagga mussels in water sources is a water quality concern. Quagga mussels are an
invasive species that was first discovered in 2007 at Lake Mead, on the Colorado River. This species of
mussels forms massive colonies in short periods of time, disrupting ecosystems and blocking water
intakes. They can cause significant disruption and damage to water distribution systems. MET has had
success in controlling the spread and impacts of the quagga mussels within the CRA, however the future
could require more extensive maintenance and reduced operational flexibility than current operations
allow. It also resulted in MET eliminating deliveries of CRA water into DVL to keep the reservoir free from
quagga mussels (MET, 2021).
7.2.3.2 Groundwater
OCWD is responsible for managing the OC Basin. To maintain groundwater quality, OCWD conducts an
extensive monitoring program that serves to manage the OC Basin's groundwater production, control
groundwater contamination, and comply with all required laws and regulations. A network of nearly
700 wells provides OCWD a source for samples, which are tested for a variety of purposes.
OCWD collects samples each month to monitor Basin water quality. The total number of water samples
analyzed varies year-to-year due to regulatory requirements, conditions in the basin and applied research
and/or special study demands. These samples are collected and tested according to approved federal
and state procedures as well as industry-recognized quality assurance and control protocols (City of
La Habra et al., 2017).
Although PFAS have not been detected in the City's wells, 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
arcadis com
7-5
975
Huntington Beach 2020 Urban Water Management Plan
DOW'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 (GAC) or ion exchange (IX) 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 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).
Salinity is a significant water quality problem in many parts of Southern California, including Orange
County. Salinity is a measure of the dissolved minerals in water including both TDS and nitrates.
OCWD continuously monitors the levels of TDS in wells throughout the OC Basin. TDS currently has a
California Secondary MCL of 500 mg/L. The portions of the OC Basin with the highest levels are
generally located in the cities of Irvine, Tustin, Yorba Linda, Anaheim, and Fullerton. There is also a broad
area in the central portion of the OC Basin where TDS ranges from 500 to 700 mg/L. Sources of TDS
include the water supplies used to recharge the OC Basin and from onsite wastewater treatment systems,
also known as septic systems. The TDS concentration in the OC Basin is expected to decrease over time
as the TDS concentration of GWRS water used to recharge the OC Basin is approximately 50 mg/L
(City of La Habra et al., 2017).

7-6
976
Huntington Beach 2020 Urban Water Management Plan
Nitrates are one of the most common and widespread contaminants in groundwater supplies, originating
from fertilizer use, animal feedlots, wastewater disposal systems, and other sources. The MCL for nitrate
in drinking water is set at 10 mg/L. OCWD regularly monitors nitrate levels in groundwater and works with
producers to treat wells that have exceeded safe levels of nitrate concentrations. OCWD manages the
nitrate concentration of water recharged by its facilities to reduce nitrate concentrations in groundwater.
This includes the operation of the Prado Wetlands, which was designed to remove nitrogen and other
pollutants from the Santa Ana River before the water is diverted to be percolated into OCWD's surface
water recharge system.
Although water from the Deep Aquifer System is of very high quality, it is amber-colored and contains a
sulfuric odor due to buried natural organic material. These negative aesthetic qualities require treatment
before use as a source of drinking water. The total volume of the amber-colored groundwater is estimated
to be approximately 1 MAF.
There are other potential contaminants that are of concern to and are monitored by OCWD. These
include:
• Methyl Tertiary Butyl Ether (MTBE)— MTBE is an additive to gasoline that increases octane
ratings but became a widespread contaminant in groundwater supplies. The greatest source of
MTBE contamination comes from underground fuel tank releases. The primary MCL for MTBE in
drinking water is 13 pg/L.
• Volatile Organic Compounds (VOC)—VOCs come from a variety of sources including industrial
degreasers, paint thinners, and dry cleaning solvents. Locations of VOC contamination within the
OC Basin include the former El Toro Marine Corps Air Station, the Shallow Aquifer System, and
portions of the Principal Aquifer System in the Cities of Fullerton and Anaheim.
• NDMA — NDMA is a compound that can occur in wastewater that contains its precursors and is
disinfected via chlorination and/or chloramination. It is also found in food products such as cured
meat, fish, beer, milk, and tobacco smoke. The California Notification Level for NDMA is 10 ng/L
and the Response Level is 300 ng/L. In the past, NDMA has been found in groundwater near the
Talbert Barrier, which was traced to industrial wastewater dischargers.
• 1,4-Dioxane— 1,4-Dioxane is a suspected human carcinogen. It is used as a solvent in various
industrial processes such as the manufacture of adhesive products and membranes.
• Perchlorate— Perchlorate enters groundwater through application of fertilizer containing
perchlorate, water imported from the Colorado River, industrial or military sites that have
perchlorate, and natural occurrence. Perchlorate was not detected in 84% of the 219 production
wells tested between the years 2010 through 2014.
• Selenium — Selenium is a naturally occurring micronutrient found in soils and groundwater in the
Newport Bay watershed. The bio-accumulation of selenium in the food chain may result in
deformities, stunted growth, reduced hatching success, and suppression of immune systems in
fish and wildlife. Management of selenium is difficult as there is no off-the-shelf treatment
technology available.
• Constituents of Emerging Concern (CEC) —CECs are either synthetic or naturally occurring
substances that are not currently regulated in water supplies or wastewater discharged but can
arcadis corn
7-7
977
Huntington Beach 2020 Urban Water Management Plan
be detected using very sensitive analytical techniques. The newest group of CECs include
pharmaceuticals, personal care products, and endocrine disruptors. OCWD's laboratory is one of
a few in the state of California that continuously develops capabilities to analyze for new
compounds (City of La Habra et al., 2017).
7.2.4 Locally Applicable 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 are able to meet a majority of their demands through groundwater with very
little limitation, except for the OCWD BPP. For the agencies in southern Orange County, most of their
demands are met with imported water where their limitation is based on the capacity of their system,
which is very robust.
However, if a major earthquake on the San Andreas Fault occurs, it will be damaging to 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 has 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,
2021).
7.3 Water Service Reliability Assessment
This Section assesses the City's reliability to provide water services to its customers under various
hydrological conditions. This is completed by comparing the projected long-term water demand (Section
4), to the projected water supply sources available to the City (Section 6), in five-year increments, for a
normal water year, a single dry water year, and a drought lasting rive consecutive water years.
7.3.1 Normal Year Reliability
The water demand forecasting model developed for the Demand Forecast TM (described in Section
4.3.1), to project the 25-year demand for Orange County water agencies, also isolated the impacts that
weather and future climate can have on water demand through the use of a statistical model. The
explanatory variables of population, temperature, precipitation, unemployment rate, drought restrictions,
and conservation measures were used to create the statistical model. The impacts of hot/dry weather
condition are reflected as a percentage increase in water demands from the average condition. The
average (normal) demand is represented by the average water demand of FY 2017-18 and FY 2018-19
(CDM Smith, 2021).
The City is 100 percent reliable for normal year demands from 2025 through 2045 (Table 7-2) due to
diversified supply and conservation measures. The City has entitlements to receive imported water from
MET through MWDOC via connections to MET's regional distribution system. For simplicity, the table
shows supply to balance demand in the table. However, the City can purchase more MET water through
MWDOC, should the need arise. The City has entitlements to receive imported water from MET through

MWDOC via connections to MET's regional distribution system. All imported water supplies are assumed
available to the City from existing water transmission facilities, as per MET's and MWDOC's
2020 UWMPs. The demand and supplies listed in Table 7-2 also include local groundwater supplies that
are available to the City through OCWD by an assumed BPP of 85%, per Section 6.3.4.

6.1, respectively.
7.3.2 Single Dry Year Reliability
A single dry year is defined as a single year of minimal to no rainfall within a period where average
precipitation is expected to occur. The water demand forecasting model developed for the Demand
Forecast TM (described in Section 4.3.1) 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 Appendix E.
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. A comparison between the supply and the demand in a single
dry year is shown in (Table 7-3). For simplicity, the table shows supply to balance demand in the table.
However, the City can purchase more MET water through MWDOC, should the need arise.

NOTES:
It is conservatively assumed that a single dry year demand is 6%greater than each respective
year's normally projected total water demand. Groundwater is sustainably managed through the
BPP and robust management measures (Section 6.3.4 and Appendix G) and based on MET's and
MWDOC's UWMPs, imported water is available to close any potable water supply gap that local
sources cannot meet (Section 7.5.1).
7.3.3 Multiple Dry Year Reliability
Assessing the reliability to meet demand for five consecutive dry years is a new requirement for the
2020 UWMP, as compared to the previous requirement of assessing three or more consecutive dry years.
Multiple dry years are defined as five or more consecutive dry years with minimal rainfall within a period of
average precipitation. The water demand forecasting model developed for the Demand Forecast TM
(described in Section 4.3.1) 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). It is conservatively
assumed that a five consecutive dry year scenario is a repeat of the single dry year over five consecutive
years.
Even with a conservative demand increase of 6% each year for five consecutive years, the City is
capable of meeting all customers' demands from 2025 through 2045 (Table 7-4), with significant reserves
held by MET and conservation. For simplicity, the table shows supply to balance demand in the table.
However, the City can purchase more MET water through MWDOC, should the need arise.

Appendix G) and based on MET's and MWDOC's UWMPs, imported water is available to close any potable
water supply gap that local sources cannot meet (Section 7.5.1)-

7.4 Management Tools and Options
Existing and planned water management tools and options for the City and MWDOC's service area that
seek to maximize local resources and result in minimizing the need to import water are described below.
• Reduced Delta Reliance: MET has demonstrated consistency with Reduced Reliance on the
Delta Through Improved Regional Water Self-Reliance (Delta Plan policy WR P1) by reporting
the expected outcomes for measurable reductions in supplies from the Delta. MET has improved
its self-reliance through methods including water use efficiency, water recycling, stormwater
capture and reuse, advanced water technologies, conjunctive use projects, local and regional
water supply and storage programs, and other programs and projects. In 2020, MET had a
602,000 AF change in supplies contributing to regional-self-reliance, corresponding to a
15.3%change, and this amount is projected to increase through 2045 (MET, 2021). For detailed
information on the Delta Plan Policy WR P1, refer to Appendix C.
• The continued and planned use of groundwater: The water supply resources within
MWDOC's service area are enhanced by the existence of groundwater basins that account for
the majority of local supplies available and are used as reservoirs to store water during wet years
and draw from storage during dry years, subsequently minimizing MWDOC's reliance on
imported water. Groundwater basins are managed within a safe basin operating range so that
groundwater wells are only pumped as needed to meet water use. Although MWDOC does not
produce or manage recycled water, MWDOC supports and partners in recycled water efforts,
including groundwater recharge. The City is currently planning for various well improvement
projects (Section 6.9).
• Groundwater storage and transfer programs: MWDOC and OCWD's involvement in
SARCCUP includes participation in a CUP that improves water supply resiliency and increases
available dry-year yield from local groundwater basins. The groundwater bank has 137,000 AF of
storage (OCWD, 2020b). Additionally, MET has numerous groundwater storage and transfer
Programs in which MET endeavors to increase the reliability of water supplies, including the
AVEK Waster Agency Exchange and Storage Program and the High Desert Water Bank
Program. The IRWD Strand Ranch Water Banking Program has approximately 23,000 AF stored
for IRWD's benefit, and by agreement, the water is defined to be an "Extraordinary Supply" by
MET and counts essentially 1:1 during a drought/water shortage condition under MET's Water
Supply Allocation Plan. In addition, MET has encouraged storage through its cyclic and
conjunctive use programs that allow MET to deliver water into a groundwater basin in advance of
agency demands, such as the Cyclic Storage Agreements under the Main San Gabriel Basin
Judgement.
• Water Loss Program: The water loss audit program reduces MWDOC's dependency on
imported water from the Delta by implementing water loss control technologies after assessing
audit data and leak detection.
• Increased use of recycled water: MWDOC partners with local agencies in recycled water
efforts, including OCWD to identify opportunities for the use of recycled water for irrigation
purposes, groundwater recharge and some non-irrigation applications. OCWD's GWRS and
GAP allow Southern California to decrease its dependency on imported water and create a local

and reliable source of water that meet or exceed all federal and state drinking level standards.
Expansion of the GWRS is currently underway to increase the plant's production to 130 MGD,
and further reduce reliance on imported water.
• Implementation of demand management measures during dry periods: During dry periods,
water reduction methods to be applied to the public through the retail agencies, will in turn reduce
MWDOC's overall demands on MET and reliance on imported water. MWDOC is assisting its
retail agencies by leading the coordination of Orange County Regional Alliance for all of the retail
agencies in Orange County. MWDOC assists each retail water supplier in Orange County in
analyzing the requirements of and establishing their baseline and target water use, as guided by
DWR. The City's specific demand management measures (DMMs) are further discussed in
Section 9.
7.5 Drought Risk Assessment
Water Code Section 10635(b) requires every urban water supplier include, as part of its UWMP, a
DRA for its water service as part of information considered in developing its DMMs and water supply
projects and programs. The DRA is a specific planning action that assumes the City is experiencing a
drought over the next five years and addresses the City's water supply reliability in the context of
presumed drought conditions. Together, the water service reliability assessment (Sections 7.1 through
7.3), DRA, and WSCP (Section 8 and Appendix H) allow the City to have a comprehensive picture of its
short-term and long-term water service reliability and to identify the tools to address any perceived or
actual shortage conditions.
Water Code Section 10612 requires the DRA to be based on the driest five-year historic sequence of the
City's water supply. However, Water Code Section 10635 also requires that the analysis consider
plausible changes on projected supplies and demands due to climate change, anticipated regulatory
changes, and other locally applicable criteria.
The following sections describe the City's methodology and results of its DRA.
7.5.1 DRA Methodology
The water demand forecasting model developed for the Demand Forecast TM (described in Section 4.3.1
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 average 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 region encompassing
the City's service area (CDM Smith, 2021).
Locally, the five-consecutive years of FY 2011-12 through FY 2015-16 represent the driest five
consecutive year historic sequence for the City's water supply. This period that spanned water years
2012 through 2016 included the driest four-year statewide precipitation on record (2012-2015) and the
smallest Sierra Cascades snowpack on record (2015, with 5% of average). It was marked by
extraordinary heat: 2014, 2015 and 2016 were California's first, second and third warmest year in terms
of statewide average temperatures. Locally, Orange County rainfall for the five-year period totaled
36 inches, the driest on record.

Huntington Beach 2020 Urban Water Management Plan
As explained in Section 6, the City currently relies on, and will continue to rely on, two main water
sources: local groundwater and imported water supply from MWDOC / MET. The City maximizes local
water supply use before the purchase of imported water. The difference between total forecasted potable
demands and local groundwater supply projections is the demand on MWDOC's imported water supplies,
which are supplied by MET. Local groundwater supply for the City comes from the OC Basin and is
dictated by the BPP set annually by OCWD. Therefore, the City's DRA focuses on the assessment of
imported water from MWDOC /MET, which will be used to close any local water supply gap. This
assessment aligns with the DRA presented in MWDOC's 2020 UWMP.
Water Demand Characterization
All of MWDOC's water supplies are purchased from MET, regardless of hydrologic conditions. As
described in Section 6.2, MET's supplies are from the Colorado River, SWP, and in-region storage. In its
2020 UWMP, MET's DRA concluded that even without activating WSCP actions, MET can reliably
provide water to all of their member agencies, including MWDOC, and in effect the City, assuming a
five -year drought from FY 2020-21 through FY 2024-25. Beyond this, MET's DRA indicated a surplus of
supplies that would be available to all of its member agencies, including MWDOC, should the need arise.
Therefore, any increase in demand that is experienced in MWDOC's service area, which includes the
City, will be met by MET's water supplies.
Based on the Demand Forecast TM, in a single dry year, demand is expected to increase by 6% above a
normal year. Both MWDOC and the City's DRA conservatively assumes a drought from FY 2020-21
through FY 2024-25 is a repeat of the single dry year over five consecutive years.
The City's demand projections were developed as a part of the Demand Forecast TM, led by MWDOC.
As a part of this study, MWDOC first estimated total retail demand for its service area. This was based on
estimated future demands using historical water use trends, future expected water use efficiency
measures, additional projected land-use development, and changes in population. The City's projected
water use, linearly interpolated per the demand forecast, is presented annually for the next five years in in
Table 4-2. Next, MWDOC estimated the projections of local supplies derived from current and expected
local supply programs from their member agencies. Finally, the demand model calculated the difference
between total forecasted demands and local supply projections. The resulting difference between total
demands net of savings from conservation and local supplies is the expected regional demands on
MWDOC from their member agencies, such as the City.
Water Supply Characterization
MWDOC's assumptions for its supply capabilities are discussed and presented in five-year increments
under its 2020 UWMP water reliability assessment. For MWDOC's DRA, these supply capabilities are
further refined and presented annually for the years 2021 to 2025 by assuming a repeat of historic
conditions from FY 2011-12 to FY 2015-16. For its DRA, MWDOC assessed the reliability of supplies
available to MWDOC through MET using historical supply availability under dry-year conditions.
MET's supply sources under the Colorado River, SWP, and in-region supply categories are individually
listed and discussed in detail in MET's UWMP. Future supply capabilities for each of these supply
sources are also individually tabulated in Appendix 3 of MET's UWMP, with consideration for plausible
changes on projected supplies under climate change conditions, anticipated regulatory changes, and
other factors. MWDOC's supplies are used to meet consumptive use, surface water and groundwater
arcades corn

recharge needs that are in excess of locally available supplies. In addition, MWDOC 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.
7.5.2 Total Water Supply and Use Comparison
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 (Table 7-5).
For simplicity, the table shows supply to balance the modeled demand in the table. However, the City can
purchase more MET water from MWDOC, should the need arise.

Notes:
Groundwater is sustainably managed through the BPP and robust management measures (Section 6.3.4
and Appendix G), direct and indirect recycled water uses provide additional local supply (Section 6.6),
and based on MET's and MWDOC's UWMPs, imported water is available to close any potable water
supply gap that local sources cannot meet (Section 7.5.1).
7.5.3 Water Source Reliability
Locally, approximately 77% (BPP for Water Year 2021-22) of the City's total water supply can rely on
OC Basin groundwater through FY 2024-25. The BPP is projected to increase to 85% starting in
FY 2024-25. Based on various storage thresholds and hydrologic conditions, OCWD, who manages the
OC Basin, has numerous management measures that can be taken, such as adjusting the BPP or
arcadis.corn

Huntington Beach 2020 Urban Water Management Plan
seeking additional supplies to refill the basin, to ensure the reliability of the Basin. For more information
on the OC Basin's management efforts, refer to Section 6.3.
Additionally, the City's use of indirect recycled water (OCWD GWRS) should also be considered.
The ability to continue producing water locally greatly improves the City's water reliability. More detail on
these programs is available in Section 6.6.
Moreover, even though they would not normally be considered part of the City's water portfolio, the
emergency interconnections the City has with the Cities of Seal Beach, Fountain Valley, and Westminster
could help mitigate any water supply shortages in a non-drought situation, though shortages are not
expected. Emergency interconnections are described in Section 6.8.
The City's DRA concludes that its water supplies meet total water demand, assuming a five-year
consecutive drought from FY 2020-21 through FY 2024-25 (Table 7-5). For simplicity, the table shows
supply to balance the modeled demand in the table. However, the City can purchase more MET water
from MWDOC, should the need arise.
As detailed in Section 8, the City has in place a robust WSCP and comprehensive shortage response
planning efforts that include demand reduction measures and supply augmentation actions. However,
since the City's DRA shows a balance between water supply and demand, no water service reliability
concern is anticipated and no shortfall mitigation measures are expected to be exercised over the next
five years. The City and its wholesale supplier, MWDOC, will periodically revisit its representation of the
supply sources and of the gross water use estimated for each year, and will revise its DRA if needed.

8 WATER SHORTAGE CONTINGENCY PLANNING
8.1 Layperson Description
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.
Water Code Section 10632 requires that every urban water supplier that serves more than 3,000 AFY or
have more than 3,000 connections prepared and adopt a standalone WSCP as part of its UWMP. The
WSCP is required to plan for a greater than 50% supply shortage. This WSCP due to be updated based
on new requirements every five years and will be adopted as a current update for submission to DWR by
July 1, 2021.
8.2 Overview of the WSCP
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
processes and procedures documented in the WSCP, which are given legal authority through the
WSCP Response Ordinance. This way, when shortage conditions arise, the City's governing body, its
staff, and the public can easily identify and efficiently implement pre-determined steps to mitigate a water
shortage to the level appropriate to the degree of water shortfall anticipated. Figure 8-1 illustrates the
interdependent relationship between the three procedural documents related to planning for and
responding to water shortages.

A copy of the City's WSCP is provided in Appendix H and includes the steps to assess if a water shortage
is occurring, and what level of shortage drought actions to trigger the best response as appropriate to the
water shortage conditions. WSCP has prescriptive elements, including an analysis of water supply
reliability; the drought shortage 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 water supply and demand assessment;
monitoring and reporting requirements to determine customer compliance; reevaluation and improvement
procedures for evaluating the WSCP.

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.
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. The City has adopted water shortage levels consistent
with the requirements identified in Water Code Section 10632 (a)(3)(A) (Table 8-1).
The supply augmentation actions that align with each shortage level are described in DWR Table 8-3
(Appendix B). These augmentations represent short-term management objectives triggered by the WSCP
and do not overlap with the long-term new water supply development or supply reliability enhancement
projects.
The demand reduction measures that align with each shortage level are described in DWR Table 8-2
(Appendix B). This table also estimates the extent to which that action will reduce the gap between
supplies and demands to demonstrate 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.

NOTES:
Water shortage contingency planning is a strategic planning process to prepare for and respond to water
shortages. Detailed planning and preparation can help maintain reliable supplies and reduce the impacts
of supply interruptions. This chapter provides a structured plan for dealing with water shortages,
incorporating prescriptive information and standardized action levels, along with implementation actions in
the event of a catastrophic supply interruption.
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. 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 population growth, climate change, drought, and catastrophic events. The WSCP is the City's
operating manual that is used to prevent catastrophic service disruptions through proactive, rather than
reactive, management. 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.

9 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 use of water has evolved as a result of the
development and implementation of water use efficiency programs that make good economic sense and
reflect 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 chapter communicates the City's efforts to promote conservation and to reduce demand on
water supplies. A detailed description of demand management measures is available in Appendix J.
9.1 Demand Management Measures for Retail Suppliers
The goal of the DMM section is to provide a comprehensive description of the water conservation
programs that a supplier has implemented, is currently implementing, and plans to implement in order to
meet its urban water use reduction targets. The reporting requirements for DMM has been significantly
modified and streamlined in 2014 by Assembly Bill 2067. Additionally, this section of the UWMP will
report on the role of MWDOC's programs in meeting new state regulations for complying with the
SWRCB's new Conservation Framework. These categories of demand management measures are as
follows:
• Water waste prevention ordinances;
• Metering,
• Conservation pricing;
• Public education and outreach,
• Programs to assess and manage distribution system real loss;
• Water conservation program coordination and staffing support;
• Other DMMs that have a significant impact on water use as measured in GPCD, including
innovative measures, if implemented:
• Programs to assist retailers with Conservation Framework Compliance.
9.1.1 Water Waste Prevention Ordinances
The City Council adopted the Water Conservation and Water Supply Shortage Program Ordinance
No. 4022 on April 21, 2014, per Huntington Beach Municipal Code 14.18.050. Ordinance No. 4022
establishes permanent water conservation requirements and prohibition against waste that are effective
at all times and is not dependent upon a water shortage for implementation, as follows:
• Limits on watering hours
• Limit on watering duration
• No excessive water flow or runoff
• No washing down hard or paved surfaces
• Obligation to fix leaks, break, or malfunctions
• Re-circulating water required for water fountains and decorative water features
arcadis com
9-1
993
Huntington Beach 2020 Urban Water Management Plan
• Limits on washing vehicles
• Drinking water served upon request only
• Commercial lodging establishments must provide guests option to decline daily linen services
• No installation of single pass cooling systems
• No installation of non-recirculating water systems in commercial car wash and laundry systems
• Restaurants required to use water conserving dish wash spray valves
• Commercial car wash systems
• Construction activities may not use potable water for compaction or dust control when non-
potable water is available and must use hoses with an automatic shut-off nozzle
• Hydrants must only be used for emergencies without first obtaining a permit
• Indiscriminate use prohibited
• Measurable rainfall event- watering prohibited
In an event of a water supply shortage, the ordinance further establishes six levels of water supply
shortage response actions to be implemented during times of declared water shortage or declared water
shortage emergency, with increasing restrictions on water use in response to worsening drought or
emergency conditions and decreasing supplies. The provisions and water conservation measures to be
implemented in response to each shortage level are described in the Water Shortage Contingency Plan
(WSCP) located in Appendix H of this 2020 UWMP. The City's water conservation ordinance is included
in Appendix D of the WSCP.
The City has a water conservation hot line and a website to receive water waste complaints and water
conservation related service requests. Once a complaint is received, the City's water conservation
coordinator investigates the complaint then notifies the resident and/or tag with a water conservation
ordinance brochure accordingly. When a service request is received, a work order is filled out and
entered into the City's Work Order system known as the Huntington Beach Service Maintenance System
(HBSMS). The HBSMS is used to track data related to water waste and non-compliance on irrigation
schedule to be reported to State Water Resource Control Board. During FY 2014-15, the City also
conducted field patrol to identify water waste and non-compliance on irrigation schedule. The field
inspector leaves a door hanger and follows up with a phone call during business hours.
9.1.2 Metering
All of the City's water connections are fully metered and customers are billed for volume of use. The City
does not have any mixed-use meters (e.g., meters that measure irrigation as well as restroom uses at
parks). All new irrigation meters for commercial/industrial/institutional customers are required to be
dedicated irrigation meters.
The City uses an Advanced Metering Infrastructure (AMI) system by ACLARA. About 98 % of the City has
AMI meters installed. The City plans to be fully converted by the end of 2020. The City has 34 Data
Collection Units (DCU) operating throughout the City. The DCU receives the reads from the Meter
Transmission Unit (MTU) multiple times per day. The DCU then sends all of the captured reads to the
Network Control Center(NCC). The City is able to view hourly reads for customer's consumption.

To ensure accurate billing based on consumption, water utilities replace water meters periodically. Water
meters and their registers often lose accuracy as they age. this requirement allows the City to provide you
with continued accurate meter readings. These meter replacements are a regulatory requirement and are
not optional. They are typically replaced every 15 to 20 years.
9.1.3 Conservation Pricing
The entirety of the City is metered and this method is used to determine consumption per connection.
The charge for water service is made up of three components: (1) the basic monthly (meter) charge,
(2) the water usage or commodity charge, and 3) a capital facilities charge. The fees charged for each of
these are designed to recover the cost of providing this component to the customer.
The City's basic daily charge per meter size is shown in Table 9-1. The City usage charge is uniform at
S2.1653 per 100 cubic feet of water. These rates are effective as of July 1, 2019 and are generally
updated annually with City Council approval.

stewardship that benefit all City residents, businesses, and industries across all demographics. Several
examples are included below:
Print and Electronic Materials
MWDOC offers a variety of print and electronic materials that are designed to assist City water users of all
ages in discovering where their water comes from, what the City and other water industry professionals are
doing to address water challenges, how to use water most efficiently, and more. Through the City's robust
social media presence, award-winning website, eCurrents newsletter, media tool kits, public service
announcements, flyers, brochures, and other outreach materials, MWDOC ensures that stakeholders are
equipped with sufficient information and subject knowledge to assist them in making good behavioral and
civic choices that ultimately affect the quality and quantity of the region's water supply.
Public Events
Each year, MWDOC hosts an array of public events intended to engage a diverse range of water users in
targeted discussions and actions that homes in on their specific interests or needs. Some of these public
events include:
• MWDOC Water Policy Forums and Orange County Water Summit are innovative and
interactive symposiums that bring together hundreds of business professionals, elected officials,
water industry stakeholders, and community leaders from throughout the state for a discussion on
new and ongoing water supply challenges, water policy issues, and other important topics that
impact our water supply, economy, and public health.
• Inspection Trips of the slate's water supply systems are sponsored each year by MWDOC and
MET. Orange County elected officials, residents, business owners, and community leaders are
invited to tour key water facilities throughout the state and learn more about the critical planning,
procurement, and management of southern California's water supply, as well as the issues
surrounding delivery and management of our most precious natural resource—water.
• Community Events and Events Featuring MWDOC Mascot Ricky the Rambunctious
Raindrop provide opportunities to interact with Orange County water users in a fun and friendly
way, offer useful water-related information or education, and engage them in important
discussions about the value of water and how their decisions at home, at work, and as tax- or
ratepayers may impact Orange County's quality and quantity of water for generations to come.
Education Programs and Initiatives
Over the past several years. MWDOC has amplified its efforts in water education programs and activities
for Orange County's youngest water users. This is accomplished by continuing to grow professional
networks and partnerships that consist of leading education groups, advisors, and teachers, and by
leading the way for the City and its 28 member agencies to be key contributors of both southern California
and Orange County water-centric learning. Several key water education programs and initiatives include:
• Environmental Literacy is an individual's awareness of the interconnectedness and
interdependency between people and natural systems, being able to identify patterns and
systems within their communities, while also gathering evidence to argue points and solve
problems. By using the environment as the context for learning, K-12 students gain real-world
arcadis.com
9-4
996
Huntington Beach 2020 Urban Water Management Plan
knowledge by asking questions and solving problems that directly affect them, their families, and
their communities. This approach to K-12 education builds critical thinking skills and promotes
inquiry, and is the foundation for all MWDOC education programs, initiatives, and activities.
• MWDOC Choice School Programs have provided Orange County K-12 students water-focused
learning experiences for nearly five (5) decades. Interactive, grade-specific lessons invite
students to connect with, and learn from, their local ecosystems, guiding them to identify and
solve local water-related environmental challenges affecting their communities. Choice School
Programs are aligned with slate standards, and participation includes a dynamic in-class or virtual
presentation, and pre- and post-activities that encourage and support Science Technology
Engineering Arts and Mathematics (STEAM)-based learning and good water stewardship.
• Water Energy Education Alliance (WEEA) is a coalition of education and water and energy
industry professionals led by MWDOC that works together to build and bolster Career Technical
Education programs (CTE) for southern California high school students. These CTEs focus on
workforce pathways in the Energy, Environment, and Utility Sectors, and connections established
through this powerful southern California alliance assist stakeholders as they thoughtfully step up
their investment in the education and career success of California's future workforce.
• MWDOC Water Awareness Poster Contest is an annual activity developed to encourage
Orange County's K-12 students to investigate and explore their relationship to water, connect the
importance of good water stewardship to their daily lives, and express their conclusions creatively
through art. Each year, MWDOC receives hundreds of entries, and 40 winners from across
Orange County are invited to attend a special awards ceremony with their parents and teachers,
and Ricky the Rambunctious Raindrop.
• Boy Scouts Soil and Water Conservation Merit Badge and Girl Scouts Water Resources
and Conservation Patch Programs guide Orange County Scouts on a learning adventure of
where their water comes from, the importance of Orange County water resources, and how to be
water efficient. These STEAM-based clinics are hosted by MWDOC and include interactive
learning stations, hands-on activities, and a guided tour of an Orange County water source, water
treatment facility, or ecological reserve
• Partnerships are an integral part of achieving water-related goals that impact all Orange County
water users. MWDOC's partner list is extensive, and acts as a collective catatyst for all those
involved to grow and prosper. Some of the City's most recognized partners include local,
regional, state, and federal legislators, educators, water and energy industry leaders,
environmental groups, media, and business associations all focused on the common goals of
water education, water use efficiency, and advocacy on behalf of the region.
9.1.5 Programs to Assess and Manage Distribution System Real Loss
Senate Bill 1420 signed into law in September 2014 requires urban water suppliers that submit
UWMPs to calculate annual system water losses using the water audit methodology developed by
AWWA. SS 1420 requires the water loss audit be submitted to DWR every five years as part of the urban
water supplier's UWMP. Water auditing is the basis for effective water loss control. DWR's UWMP
Guidebook include a water audit manual intended to help water utilities complete the AWWA Water
arcadis.com
9-5
997
Huntington Beach 2020 Urban Water Management Plan
Audit on an annual basis. A Water Loss Audit was completed for the City which identified areas for
improvement and quantified total loss. Based on the data presented, the three priority areas identified
were customer metering inaccuracies, billed metered, and volume from own sources. Multiple criteria are
a part of each validity score and a system wide approach will need to be implemented for the City's
improvement. The City completes a system water audit to calculate water losses on an annual basis.
Expressing water loss audit results in terms of Real Losses per Service Connection per Day allows for
standardized comparison across MWDOC retailer agencies and is a metric consistent with the Water
Board's forthcoming economic model. The Real Losses per Service Connection per Day for calendar year
2019 was 22.51 gal/connection/day.
The City does not have a leak detection program. However, sudden drastic changes in monthly water bills
are monitored as customers are notified of potential leaks by either mail notification or by phone.
9.1.6 Water Conservation Program Coordination and Staffing Support
The City's Public Works Department shares the implementation and promotion of water conservation
programs as part of its duties. the City's Water Conservation Coordinator, has obtained the Water
Conservation Practitioner Certificate from the AWWA. The City's Water Conservation Coordinator
participates in the Water Use Efficiency meetings hosted by MWDOC, and works with MWDOC to
implement the DMM's. Funding for the City's water conservation program is from the City's Water Fund.
9.1.7 Other Demand Management Measures
9.1.7.1 Residential Program
MWDOC assists the City with the implementation of residential DMMs by making available the following
programs aimed at increasing landscape and indoor water use efficiency for residential customers.
High Efficiency Clothes Washer Rebate Program
The High Efficiency Clothes Washer(HECW) Rebate Program provides residential customers with
rebates for purchasing and installing HECWs that. Approximately 15% of home water use goes towards
laundry, and HECWs use 35-50% less water than standard washer models, with savings of approximately
10.500 gallons per year, per device. Devices must meet or exceed the Consortium for Energy Efficiency
(CEE) Tier 1 Standard, and a listing of qualified products can be found at ocwatersmart.com. There is a
maximum of one rebate per home.
Premium High Efficiency Toilet Rebate Program
The largest amount of water used inside a home, 30 percent, goes toward flushing the toilet.
The Premium High Efficiency Toilet (HET) Rebate Program offers incentives to residential customers for
replacing their toilets using 1.6 gallons per flush or more. Premium HETs use just 1.1 gallons of water or
less per flush, which is 20% less water than WaterSense standard toilets. In addition, Premium HETs
save an average of 9 gallons of water per day while maintaining high performance standards.

Huntington Beach 2020 Urban Water Management Plan
9.1.7.2 CII Programs
MWDOC provides a variety of financial incentives to help City businesses, restaurants, institutions, hotels,
hospitals, industrial facilities, and public sector sites achieve their efficiency goals. Water users in these
sectors have options to choose from a standardized list of water efficient equipment/devices or may
complete customized projects through a pay-for-performance where the incentive is proportional to the
amount of water saved. Such projects include high efficiency commercial equipment installation and
manufacturing process improvements.
Water Savings Incentive Program
The Water Savings Incentive Program (WSIP) is designed for non-residential customers to improve their
water efficiency through upgraded equipment or services that do not qualify for standard rebates. WSIP
is unique because it provides an incentive based on the amount of water customers actually save.
This "pay-for-performance" design lets customers implement custom projects for their sites.
Projects must save at least 10 million gallons of water to qualify for the Program and are offered from
$195 to $390 per acre foot of water saved. Examples of successfully projects include but are not limited
to changing industrial process system water, capturing condensation and using it to supplement cooling
tower supply, and replacing water-using equipment with more efficient products.
On-site Retrofit Program
The On-site Retrofit Program (ORP) provides another pay-for-performance financial incentive to
commercial, industrial and institutional property owners, including Homeowner Associations, who convert
potable water irrigation or industrial water systems to recycled water use.
Projects commonly include the conversion of mixed or dedicated irrigation meters using potable water to
irrigate with reclaimed water, or convert industrial processes use to recycled water, such as a cooling
towers. Financial incentives of up to 51,300 per AF of potable water saved are available for customer-side
on the meter retrofits. Funding is provided by MET, USBR, and DWR.
Multi-Family Premium High Efficiency Toilet Incentive Program
MWDOC makes an effort to reach all water-users in Orange County. For the Multi-Family Premium
HET Rebate Program, MWDOC targets multi-family buildings in both disadvantaged communities (DAC)
and non-DAC communities, in addition to targeting all commercial buildings, and single-family residential
homes through Premium HET device rebates.
MWDOC offers the DAC Multi-Family HET Program, a special version of the HET Program, to ensure
regardless of economic status all water-users in Orange County can benefit from the rebate.
This Program targets 3.5 gallon per flush (gpf) or greater toilets to replace them with WaterSense
Labeled 1.1 gpf or less. For this purpose, DAC are referenced as communities facing economic hardship.
This is defined using criteria established by DWR and the County of Orange, which includes communities
where the MHI is less than 85% of the Orange County MHI.
The DAC Multi-Family Program is contractor-driven, where a contractor works with building owners to
replace all of the toilets in the building(s). To avoid any cost to tenants, the rebate is $200 per toilet paid
to the contractor, essentially covering the contractor's cast, therefore, there is little to no charge to the
building owners that may be passed through to tenants. This process was formed after consulting
arcadis com
9-7
999
Huntington Beach 2020 Urban Water Management Plan
contractors and multi-family building owners in Orange County. To serve those in multi-family buildings
outside of designated DAC locations, MWDOC offers $75 per toilet through the same contractor-driven
format. An additional option is available through SoCal Water$mart, which offers up to $250 per toilet to
multi-family buildings that were built before 1994, therefore targeting buildings built before legislation
required low-flow plumbing fixtures in new construction.
Device Retrofits
MWDOC offers additional financial incentives under the SoCal Water$mart Rebate Program which offers
rebates for various water efficient devices to CII customers. Core funding is provided by MET and
supplemental funding is sourced from MWDOC via grant funds and/or retail water agencies.
9.1 .7.3 Landscape Programs
One of the most active and exciting water use efficiency sectors MWDOC provides services for are those
programs that target the reduction of outdoor water use. With close to 60% of water consumed outdoors,
this sector has been and will continue to be a focus for MWDOC and the City.
Turf Removal Program
The Orange County Turf Removal Program offers incentives to remove turf grass from residential,
commercial, and public properties throughout the County. This program is a partnership between
MWDOC, MET, and local retail water agencies. The goals of this program are to increase water use
efficiency through sustainable landscaping practices that result in multi-benefit projects across Orange
County. Participants replace their turf grass with drought-tolerant, CA Friendly, or CA Native landscaping,
and retrofit their irrigation systems to high efficiency equipment, such as drip, or remove it entirely, and
are encouraged to utilize smart irrigation timers. Furthermore, projects are required to include a
stormwater capture feature, such as a rain garden or dry stream bed, and have a minimum of three plants
per 100 square feet to increase plant density and promote healthy soils. These projects save water and
also reduce dry and wet weather runoff, increase urban biomass, and sequester more carbon than turf
landscapes.
Landscape Design and Maintenance Plan Assistance Programs
To maximize the water efficiency and quality of Orange County's Turf Removal Program Projects,
MWDOC offers free landscape designs and free landscape maintenance plans to participating residential
customers. The Landscape Design Assistance Program is offered at the beginning stages of their turf
removal project so that customers may receive a customized, professionally designed landscape to
replace their turf. Landscape designs include plant selection, layout, irrigation plans, and a stormwater
capture feature. These designs help ensure climate appropriate plants are chosen and planted by
hydrozone, that appropriate high efficiency irrigation is properly utilized, that water savings are maximized
as a result of the transformation. Landscape maintenance plans are offered after a project is complete to
ensure that the new landscape is cared for properly and water savings are maximized.
Smart Timer Rebate Program
Smart Timers are irrigation clocks that are either weather-based irrigation controllers (WBICs) or soil
moisture sensor systems. WBICs adjust automatically to reflect changes in local weather and site-specific
landscape needs, such as soil type, slopes, and plant material. When WBICs are programmed properly,
arcadis com
9-8
1000
Huntington Beach 2020 Urban Water Management Plan
turf and plants receive the proper amount of water throughout the year. During the fall months, when
property owners and landscape professionals often overwater, Smart Timers can save significant
amounts of water.
Rotating Nozzles Rebate Program
The Rotating Nozzle Rebate Program provides incentives to residential and commercial properties for the
replacement of high-precipitation rate spray nozzles with low-precipitation rate multi-stream, multi-
trajectory rotating nozzles. The rebate offered through this Program aims to offset the cost of the device
and installation.
Spray-to-Drip Rebate Program
The Spray to Drip Rebate Program offers residential, commercial, and public agency customers rebates
for converting areas irrigated by traditional high-precipitation rate spray heads to low-precipitation rate
drip irrigation. Drip irrigation systems are extremely water-efficient. Rather than spraying wide areas
subject to wind drift, overspray and runoff, drip systems use point emitters to deliver water to specific
locations at or near plant root zones. Water drips slowly from the emitters either onto the soil surface or
below ground. As a result, less water is lost to wind, evaporation, and overspray, saving water and
reducing irrigation runoff and non-point source pollution.
SoCal Water$mart Rebate Program for Landscape
The City through MWDOC also offers financial incentives under the SoCal Water$mart Rebate Program
for a variety of water efficient landscape devices, such as Central Computer Irrigation Controllers, large
rotary nozzles, and in-stem flow regulators.
Landscape Training Classes
The California Friendly and Native Landscape Training and the Turf Removal and Garden Transformation
Workshops provide education to residential homeowners, property managers, and professional
landscape contractors on a variety of landscape water efficiency practices that they can employ and use
to help design a beautiful garden using California Friendly and native plant landscaping principles. The
California Friendly and Native Landscape Class demonstrates how to: implement storm water capture
features in the landscape; create a living soil sponge that holds water; treat rainwater by a resource;
select and arrange plants to maximize biodiversity and minimize water use; and control irrigation to
minimize water waste, runoff and non-point source pollution.
The Turf Removal and Garden Transformation Workshop teaches participants how to transform thirsty
turfgrass into a beautiful, climate-appropriate water efficient garden. This class teaches how to: evaluate the
landscape's potential; plan for garden transformation; identify the type of turfgrass in the yard, remove grass
without chemicals; build healthy, living soils; select climate-appropriate plants that minimize water use and
maximize beauty and biodiversity; and implement a maintenance schedule to maintain the garden.
Qualified Water Efficient Landscape Certification (Commercial)
Since 2018, MWDOC along with the City, has offered free Qualified Water Efficient Landscaper (QWEL)
certification classes designed for landscape professionals. Classes are open to any city staff, professional
landscaper, water district employee, or maintenance personnel that would like to become a Qualified
Water Efficient Landscaper. The QWEL certification program provides 20 hours of instruction on water
arcadis coin

efficient areas of expertise such as local water supply, sustainable landscaping, soil types, irrigation
systems and maintenance, as well as irrigation controller scheduling and programing. QWEL has
received recognition from EPA WaterSense for continued promotion of water use efficiency. To earn the
QWEL certification, class participants must demonstrate their ability to perform an irrigation audit as well
as pass the QWEL exam. Successful graduates will be listed as a Certified Professional on the
WaterSense website as well as on MWDOC's landscape resources page, to encourage Turf Removal
participants or those making any landscape improvements to hire a QWEL certified professional.
Started in December 2020, a hybrid version of QWEL is available in conjunction with the California
Landscape Contractors Association's Water Management Certification Program. This joint effort allows
landscape industry an opportunity to obtain two nationally recognized EPA WaterSense Professional
Certifications with one course and one written test. This option is offered through MET.
Orange County Water Smart Gardens Resource Page
MWDOC's Orange County Water Smart Gardens webpage provides a surplus of helpful guides and fact
sheets, as well as an interactive photo gallery of water-saving landscape ideas. The purpose of this
resource is to help Orange County residents find a broad variety of solutions for their water efficient
landscaping needs. This includes a detailed plant database with advanced to search features; photo
and/or video-based garden tours; garden gallery with images organized into helpful landscape categories
such as back yards, hillsides, full sun, and/or shade with detailed plant information; and the ability to
select and store plants in a list that the user can print for use when shopping.
Additional technical resources are available such as a watering calculator calibrated for local
evapotranspiration rates, and a garden resources section with fact sheets on sustainable landscape
fundamentals, water and soil management, composting, solving run-off, and other appropriate topics.
Web page is accessible through mwdoc.com and directly at www.ocwatersmartgardens.com.
9.2 Implementation over the Past Five Years
During the past five years, FY 2015-16 to 2020-21, the City, with the assistance of MWDOC, has
continued water use efficiency programs for its residential, CII, and landscape customers as described in
Table 9-2. Implementation data is provided in Appendix I. The City will continue to implement all
applicable programs in the next five years.

9.3 Water Use Objectives (Future Requirements)
To support Orange County retailers with SB 606 and AB 1668 compliance (Conservation Framework),
MWDOC is providing multi-level support to members agencies to ensure they meet the primary goals of
the legislation including to Use Water More Wisely and to Eliminate Water Waste. Beginning in 2023,
Urban water suppliers are required to calculate and report their annual Urban water use objective (WUO),
submit validated water audits annually, and to implement and report best management practice (BMP)
CII performance measures.
Urban Water Use Objective
An Urban Water Supplier's urban WUO is based on efficient water use of the following:
• Aggregate estimated efficient indoor residential water use,
• Aggregate estimated efficient outdoor residential water use,
• Aggregate estimated efficient outdoor irrigation landscape areas with dedicated irrigation meters
or equivalent technology in connection with CII water use;
• Aggregate estimated efficient water losses;
• Aggregate estimated water use for variances approved the State Water Board;
• Allowable potable reuse water bonus incentive adjustments.
MWDOC offers a large suite of programs, described in detail throughout section 1.3.6, that will assist
Orange County retailers in meeting and calculating their WUO.

In addition, MWDOC is providing support to agencies to assist with the calculation of WUOs. DWR will
provide residential outdoor landscape measurements; however, Urban Water Suppliers are responsible
for measuring landscape that is irrigated/irrigable by dedicated irrigation meters. MWDOC is contracting
for consultant services to assist agencies in obtaining these measurements. Services may include but are
not limited to:
• Accounting/database clean up (e.g., data mining billing software to determine dedicated irrigation
customers);
• Geolocation of dedicated irrigation meters,
• In-field measurements;
• GIS/Aerial imagery measurements;
• Transformation of static/paper maps to digital/GIS maps.
These services will help agencies organize and/or update their databases to determine which accounts
are dedicated irrigation meters and provide landscape area measurements for those accounts.
These data points are integral when calculating the WUO. MWDOC is also exploring funding options to
help reduce retail agencies' costs of obtaining landscape area measurements for dedicated irrigation
meters.
CII Performance Measures
Urban water supplies are expected to report BMPs and more for CII customers. MWDOC offers a broad
variety of programs and incentives to help CII customers implement BMPs and increase their water
efficiencies.

10 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 Supplier has to notify the public and the cities and counties within its service
area per the Water Code and hold a public hearing to receive input from the public on the UWMP.
Post adoption, the Supplier submits the UWMP to DWR and the other key agencies and makes it
available for public review.
This section provides a record of the process the City followed to adopt and implement its UWMP.
10.1 Overview
Recognizing that close coordination among other relevant public agencies is key to the success of its
UWMP, the City worked closely with many other entities, including representation from diverse social,
cultural, and economic elements of the population within the City's service area, to develop and update
this planning document. The City also encouraged public involvement through its public hearing process,
which provided residents with an opportunity to learn and ask questions about their water supply
management and reliability. Through the public hearing, the public has an opportunity to comment and
put forward any suggestions for revisions of the Plan.
Table 10-1 summarizes external coordination and outreach activities carried out by the City and their
corresponding dates. The UWMP checklist to confirm compliance with the Water Code is provided in
Appendix A.

NOTES:
The City's water supply planning relates to the policies, rules, and regulations of its regional and local
water providers. The City is dependent on imported water from MET through MWDOC, its regional
wholesaler. The City is also dependent on groundwater from OCWD, the agency that manages the
OC Basin. As such, the City involved the relevant agencies in this 2020 UWMP at various levels of
contribution as described below.
MWDOC provided assistance to the City's 2020 UWMP development by providing much of the data and
analysis such as population projections from the California State University at Fullerton CDR and the
information quantifying water availability to meet the City's projected demands for the next 25 years, in
five-year increments. Additionally, MWDOC led the effort to develop a Model Water Shortage Ordinance
that its retail suppliers can adopt as is or customize and adopt as part of developing their WSCPs.
This 2020 UWMP was developed in collaboration with MWDOC's 2020 UWMP to ensure consistency
between the two documents.
As a groundwater producer who relies on supplies from the OCWD-managed OC Basin, the City
coordinated the preparation of this 2020 UWMP with OCWD. Several OCWD documents, such as the
Groundwater Reliability Plan, Engineer's Report, and 2017 Basin 8-1 Alternative were used to retrieve the
required relevant information, including the projections of the amount of groundwater the City is allowed
to extract in the 25-year planning horizon.
The various planning documents of the key agencies that were used to develop this UWMP are listed in
Section 2.2.1.

10.3 Public Participation
The City encouraged community and public interest involvement in the Plan update through a public
hearing and inspection of the draft document on June 7, 2021. As part of the public hearing, the City
discussed adoption of the UWMP, SBx7-7 baseline values, compliance with the water use targets
(Section 5), implementation, and economic impacts of the water use targets (Section 9).
Copies of the draft plan were made available on the City's website.
Notices of public meetings were posted in the City Hall. Legal public notices for the meeting were
published in the local newspaper and posted at City facilities. A copy of the published Notice of Public
Hearing is included in Appendix K.
The hearing was conducted during a regularly scheduled meeting of the City Council,
10.4 UWMP Submittal
The City Council reviewed and approved the 2020 UWMP at its June 7, 2021 meeting after the public
hearing. See Appendix L for the resolution approving the Plan.
By July 1, 2021, the City's adopted 2020 UWMP was filed with DWR, California State Library, the County
of los Angeles, the County of Orange and the cities within its service area. The submission to DWR was
done electronically through the online submittal tool—WUE Data Portal. The City will make the Plan
available for public review on its website no later than 30 days after filing with DWR.
10.5 Amending the Adopted UWMP or WSCP
Based on DWR's review of the UWMP, the City will make any amendments in its adopted UWMP, as
required and directed by DWR and will follow each of the steps for notification, public hearing, adoption,
and submittal for the amending the adopted UWMP.
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.

Huntington Beach 2020 Water Shortage Contingency Plan
1 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 Water Shortage Contingency Plan (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 Huntington 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 Water Code Section 16032
requirements.
1027
1-1
Huntington Beach 2020 Water Shortage Contingency Plan
Section 1 Introduction and WSCP Overview gives an overview of the WSCP fundamentals.
Section 2 Background provides a background on the City of Huntington Beach'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
1028
1-2
Huntington Beach 2020 Water Shortage Contingency Plan
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 provide 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.

2.2 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 Califomia counties. Its service area covers the Southern Califomia 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
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 Stale 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

2.3 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 mix
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 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. 2021a).
2.3.2 MET Water Supply Allocation Plan
MET 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.
1035
2-6
Huntington Beach 2020 Water Shortage Contingency Plan
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, 2021a).
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 greater than 50% supply shortage. 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).
1036

Huntington Beach 2020 Water Shortage Contingency Plan
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
1037
2-8
Huntington Beach 2020 Water Shortage Contingency Plan
according to the retail agency's prorated share (acre-feet 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 (Huntington 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 also has added reliability through
receiving the majority of its water supply from groundwater from the OC Basin and supplemental imported
supplies from MET/MWDOC. 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 (Huntington 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 1st 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.
103Q 1
Huntington Beach 2020 Water Shortage Contingency Plan
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 Percentage (BPP) and on MWDOCs
Annual Assessment outcomes.
The City is supplied 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 in 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 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 Public Works Director, or designee,
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.
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 has 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, 2021 b).
3.2.2.3 Water Supply
As detailed in the City's 2020 UWMP, the City meets all of its customers' demands with a combination of local
groundwater from the OC Basin and imported water from MWDOC/MET. The City's main source of water supply
is groundwater, with imported water making up the rest of the City's water supply portfolio. In fiscal year (FY)
2019-20, the City relied on 70% groundwater and 30% imported water. It is projected that by 2045, the water
104 2 4
Huntington Beach 2020 Water Shortage Contingency Plan
supply portfolio will change to approximately 85% groundwater and 15% imported water, reflecting the increase in
OCWD's BPP to 85% beginning in 2025 (Huntington 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 (Huntington Beach, 2021). Water
demands in a five-year consecutive drought are calculated as a 6% 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 scenarios 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 Slate 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.
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 water use efficiency (Huntington Beach, 2021).

Huntington Beach 2020 Water Shortage Contingency Plan
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.
Specifically for the City, as of July 2021, there are no foreseen near-term infrastructure issues that would impact
supply; however, the City is planning to update the Water Master Plan in 2022 and will update infrastructure
considerations based on Water Master Plan outcomes.
3.2.2.7 Other Factors
For the Annual Assessment, any known issues related to water quality would be considered for their potential
effects on water supply reliability.
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.
Although PFAS have not been detected in the City's wells, 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 (ppl), 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
these PFAS treatment systems are designed to ensure the groundwater supplied by Producer wells can be
io4g 6
Huntington Beach 2020 Water Shortage Contingency Plan
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 acre-feet (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 include the six standard water shortage levels that
represent shortages from the normal reliability as determined in the Annual Assessment. The shortage levels
have been standardized to provide a consistent regional and statewide approach to conveying the relative
severity of water supply shortage conditions. This is an outgrowth of the severe statewide drought of 2012-2016,
and the widely recognized public communication and state policy uncertainty associated with the many different
local definitions of water shortage Levels.
The six standard water shortage levels correspond to progressively increasing estimated shortage conditions (up
to 10, 20, 30, 40, 50%, and greater than 50% shortage compared to the normal reliability condition) and align with
the response actions the Supplier would implement to meet the severity of the impending shortages.

NOTES:
3.4 Shortage Response Actions
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.
1047
3-9
Huntington Beach 2020 Water Shortage Contingency Plan
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
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. The City can alter
maintenance cycles, such as system flushing, and defer planned construction activities and capital improvement
projects to limit or defer planned system outages. The City has one pressure zone and all water sources (the
City's wells and connections to MET) pump directly into the system, in which the City would have to adjust control
valves to lower the pressure in the system and restrict flows for operational control.
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 Huntington Beach Municipal Code Chapter 14.18 Water Management Program (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).
101810
Huntington Beach 2020 Water Shortage Contingency Plan
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 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 Sacramentro-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:
10
I-11
Huntington Beach 2020 Water Shortage Contingency Plan
• 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.
• 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 Huntington 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, and the City's local
HMP, 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.
105012
Huntington Beach 2020 Water Shortage Contingency Plan
• 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
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 (MWDOC, 2019).
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 (Huntington Beach, 2017):
• Conduct a survey of seismically vulnerable buildings in the City, including soft first-story and older
concrete structures. Ensure that the survey remains accurate through regular survey updates.
• Develop an incentive program for property owners to retrofit seismically vulnerable structures.
• Require a seismic hazard assessment for new buildings or significant retrofits within the Alquist-Priolo
Earthquake Fault Zone or in an area with high liquefaction risk. Require buildings in seismic hazard-prone
areas to reduce their vulnerability as appropriate.
• Explore adopting amendments to the City's building code requiring new buildings to exceed the minimum
seismic standards in the state Buildings Standards Code. Emphasize constructing buildings to remain
safely habitable and functional following an earthquake.
• Incorporate the possibility of a major urban fire or tsunami following a significant earthquake into Fire
Department training and emergency response procedures.
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.
19113
Huntington Beach 2020 Water Shortage Contingency Plan
3.5 Communication Protocols
Timely and effective communication is a key element of the WSCP implementation. Per 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 Plan is documented in Appendix
C.
3.6 Compliance and Enforcement
Per the 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 Communication Protocols and customer enforcement, appeal, and exemption
procedures are defined in the City's existing Municipal Code Chapter 14.18 Water Management Program
(Appendix B). The City intends 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 of Huntington Beach to implement and enforce its shortage response in the City's Municipal Code
Chapter 14.18 Water Management Program (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 3-2 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.

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
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 14.18 Water Management Program
(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.
103315
Huntington Beach 2020 Water Shortage Contingency Plan
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.
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
I'l 6
Huntington Beach 2020 Water Shortage Contingency Plan
course of preparing the Annual Assessment each year, City staff will routinely consider the functionality the
overall WSCP and will prepare recommendations for City Council 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 14.18
Water Management Program (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 the City's website in advance of the public
hearing on June 7, 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 June 7, 2021, at the City Council
meeting. The City Council reviewed and approved the 2020 UWMP and the WSCP at its June 7, 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 fling 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.
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.

EXHIBIT "A"
APPENDIX "L" - REDUCED DELTA RELIANCE
REPORTING
1075
The City of Huntington Beach
REDUCED DELTA RELIANCE REPORTING
L.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 Pl, Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance (WR P1).
WR Pl 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) Water shall not be exported from, transferred through,or used in the Delta if all of thefollowing apply:
(1) One or more water suppliers that would receive water as a result of the export, transfer, or use hove failed
to adequately contribute to reduced reliance on the Delta and improved regional self-reliance consistent with
all of the requirements listed inparograph
(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 PI subsection(c)(1)further defines what adequately contributing to reduced reliance on the Delta means in terms
of(a)(1)above.
(c)(I) Wotersuppliers that hove 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 5, Parts 2.55, 2.6, ond2.8;
(B) 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 technicallyfeasible which reduce reliance on the Delta;and
(C) Included in the Plan,commencing in 2015, the expected outcome for measurable 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 watersupply, consistent with Water
Code section 1011(o).
The analysis and documentation provided below include all of the elements described in WR Pl(c)(1) that need to
be included in a water supplier's UWMP to support a certification of consistency for a future covered action.
1076
L.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 Huntington Beach (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 18,185 AF from the
2010 baseline; this represents an increase of about 46.0 percent of 2025 normal water year retail demands
(Table L-2).
• Long-term (2040) — Normal water year regional self-reliance is expected to increase by nearly 20,830 AF
from the 2010 baseline, this represents an increase of about 51.7 percent of 2045 normal water year retail
demands (Table L-2).
L.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 thetas 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
1077
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 how supply capability is presented to fulfill requirements of the U W MP
Act versus how supplies 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 wateryear 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 L-1 shows the results of this adjustment for the City.
Supporting narratives and documentation for the all of the data shown in Table L-1 are provided below.

Service Area Demands with Water Use Efficiency
The service area demands shown in Table L-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 L-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. Note that the City of Fullerton does not have recycled water/non-potable water demands;
this is demonstrated in Table L-1.
Total Service Area Population
The City's total service area population as shown in Table L-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 Efficiency Since Baseline
The water use efficiency numbers shown in Table L-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 L-1 were collected from the following sources:
• Baseline(2010) values—City's 2005 UWMP
• 2015 values— City's 2010 UWMP
• 2020 values—City's 2015UWMP
• 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.
LA 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 L-2 shows expected
outcomes for supplies contributing to regional self-reliance both in amount and as a percentage. The numbers shown in
Table L-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 L-2 are provided
below.
The results shown in Table L-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
18,185 AF from the 2010 baseline; this represents an increase of about 46.0 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
20,830 AF from the 2010 baseline; this represents an increase of about 51.7 percent of 2040 normal water year
1079
retail demands.

The water recycling values shown in Table L-2 reflect the total recycled water production in the service area as
described in Section 4.3 of City's UWMP. Note that Fullerton does not have recycled water production.
Advanced Water Technologies(AWT)
1080
AWT is calculated by multiplying the estimated GW production for that year (Section 6.1 of the City's UWMP) with the
percentage of Total Basin Production for that year.
L.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 (204S), 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.

L.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
1081
programs, and Metropolitan's conveyance and distribution facilities, demand management programs increase the
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
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.
1082
Metropolitan reduce its reliance on the Delta. Because California experiences dramatic swings in weather and
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
1084
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 yeartoyear 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.
1085
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 successfulfy
converted 440 sites, increasing the use of recycled water by 12,691 acre-feet per year.
Stormwater 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-
1086
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
1087
• 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 $4S0 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
for the individual member agencies or their 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.
