SUMMARY
On March 21, 2017, the City Council adopted Ordinance 1477 amending the Water Management
Plan, Article 4, Chapter 10 of the Tustin, Code of Ordinances. In 2018, the California Legislature
amended the Urban Water Management Planning Act that, among other things, mandated the
adoption of a Water Shortage Contingency Plan (WSCP) with prescribed elements as part of
the Urban Water Management Plan (UWMP). On June 1, 2021, the City Council adopted both
the 2020 UWMP and WSCP. As a result, staff has prepared Ordinance No. 1516 updating the
Water Management Plan to incorporate changes outlined in the 2020 WSCP.
RECOMMENDATION
It is recommended that the City Council Conduct the first reading by title only of Ordinance No.
1516.
FISCAL IMPACT
No fiscal impacts associated with this item.
CORRELATION TO THE STRATEGIC PLAN
This effort contributes to the fulfillment of the City's Strategic Plan Goal D: Strong Community and
Regional Relationships. Specifically, the project implements Strategy 2, which among other
things, is to enhance collaboration efforts with agencies within and outside Tustin on issues of
mutual interest and concern.
BACKGROUND
On March 21, 2017, the City Council adopted Ordinance No. 1477 amending Article 4, Chapter
10, of the Tustin, CA Code of Ordinances. Chapter 10 of Article 4 is commonly known as the
City's Water Management Plan and Ordinance 1477 established a comprehensive Water
Conservation Program pursuant to the California Water Code based upon the need to conserve
water supplies and to avoid or minimize the effects of any future shortages. The Water
Management Plan establishes regulations to be implemented during times of declared water
shortages. The current plan establishes four (4) stages of drought response actions to be
implemented in times of shortage, with increasing restrictions on water use in response to
worsening drought conditions and decreasing available supplies.

In 2018, the California Legislature amended the Urban Water Management Planning Act that,
among other things, mandated the City develop and adopt a Water Shortage Contingency Plan
(WSCP) with prescribed elements as part of the Urban Water Management Plan (UWMP).
These changes have been incorporated into Ordinance No. 1516.
The majority of changes to the Water Management Plan come in the form of increasing water
shortage levels from the existing four levels to the purposed six levels. This effort was
predominantly initiated to build continuity across the State of California in times of declared
water shortages. The WSCP provides the steps and water shortage response actions to be
taken in times of drought or water shortage conditions. Table 1 defines the Shortage Levels
and Ranges as prescribed in the WSCP and proposed ordinance.
1109111MI
Shortage Level
Percentage Shortage Range
1
Up to 10%
2

3
21 % to 30%
4
31 % to 40%
5
41 % to 50%
6
>50%
The WSCP has prescriptive elements, such as
1. 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%;
2. An estimate of potential to close supply gap for each measure;
3. Protocols and procedures to communicate identified actions for any current or predicted
water shortage conditions;
4. Procedures for an Annual Assessment;
5. Monitoring and reporting requirements to determine customer compliance; and
6. Reevaluation and improvement procedures for evaluating the WSCP.
Ordinance No. 1516 incorporates the changes reflected in the 2020 WSCP approved on June
1, 2021 and codifies the City's responses related to water supply shortages, annual supply
assessment, and customer communication and engagement efforts in times of drought and
water shortages.
Conservation has become a way -of -life for Tustin water customers as overall water use has
reduced by over 26 percent since the 1999-2000 water year, this represents a reduction of 1.2
billion gallons when comparing water use between 2021 and 2000.

The lowest water year during this span occurred in 2015-2016 at 9,098 AF. Water use efficiency
remains a priority for the City and water customer base. Tustin water customers have been well
informed and have responded accordingly. This has been accomplished through ongoing

outreach and education, as well as, rebates and incentives offered through the City, the
City's partners at the Municipal Water District of Orange County (MWDOC) and the Metropolitan
Water District of Southern California (MET). A few of the key initiatives undertaken in
partnership with MWDOC and MET include:
• Annual Water Use Efficiency School Education Programs K-12 (over 3000 TUSD
students/year)
• Turf Replacement/ California Friendly Landscaping
• Smart irrigation controllers / drip irrigation programs
• Water loss validation practices
• Acoustic leak detection services
• Water system -wide leak survey
• Urban Water Management Plan
• Water Shortage Contingency Plan
• California Drought Preparedness — OC is Water Smart
In response to the current drought and the need for strong, credible, and unified messaging from
water providers, the MWDOC Public Affairs team, in coordination with member agencies,
prepared a media/toolkit California Drought Preparedness — OC is Water Smart. This
comprehensive tool kit is full of valuable resources to help communicate clearly and effectively
with customers and stakeholders amid the drought.
MWDOC, as our representation to the MET Board, will continue to monitor drought conditions
and messages from the State, Association of California Water Agencies (ACWA), MET, and other
key influencers to ensure the Orange County voice is relevant and aligns with others. The toolkit
is the first response to messaging, and MWDOC anticipates extending the effort as more
information becomes available or conditions change.
As a MWDOC member agency, Tustin Water Services customers continue to be eligible to apply
for rebates and incentives that provide helpful tools to offset the expense of water efficient
improvements to homes and businesses, which provide years of conservation.

ORDINANCE NO. 1516
AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF TUSTIN,
CALIFORNIA, FINDING AND DETERMINING THE NECESSITY FOR
AND AMENDING THE WATER MANAGEMENT PLAN
The City Council of the City of Tustin does hereby ordain as follows:
SECTION 1: Findings. The City Council finds and determines as follows:
A. Article X, Section 2 of the California Constitution declares that waters of the State
are to be put to beneficial use, that waste, unreasonable use, or unreasonable
method of use of water be prevented, and that water be conserved for the public
welfare.
B. Conservation of current water supplies and minimization of the effects of water
supply shortages that are the result of drought are essential to the public health,
safety and welfare.
C. Regulation of the time of certain water use, manner of certain water use, design of
rates, method of application of water for certain uses, installation and use of water -
saving devices, provide an effective and immediately available means of
conserving water.
D. The California Water Code empowers any public entity which supplies water at
retail or wholesale to adopt and enforce a water conservation program to reduce
the quantity of water used by those within its service area.
E. It is essential that this ordinance take effect upon adoption to maintain preservation
of the public health or safety due to expected ongoing and reoccurring statewide
drought cycles, and based upon the facts described below.
F. California, including Orange County, experienced significant dry year conditions in
2012-2017, which lead local water agencies to declare water shortage conditions
that triggered drought actions.
G. The City of Tustin experienced a direct impact on the reliability of available water
supplies. The agency's reliability was increased through customer curtailment due
to demand management measures implemented. These actions are specified in
the adopted 2015 Urban Water Management Plan, Water Shortage Contingency
Plan chapter, adopted Water Shortage Contingency Plan actions based on levels
of drought severity, and provided the legal authority for implementation and
enforcement through the Water Management Plan Ordinance.
Ordinance No. 1516
Page 1 of 18
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
H. Following the end of the 2017 drought, the California Legislature modified the
Urban Water Management Planning Act in 2018 to include additional water
shortage planning requirements. California Water Code has significant updates in
specifically to Code Section 10632 that now mandate new elements to Urban
Water Managements and Water Shortage Contingency Plans, including an annual
drought risk assessment, State Water Shortage Levels and statewide water use
prohibitions.
The Municipal Water District of Orange County (MWDOC) has adopted a 2020
Urban Water Management Plan that includes water conservation as a necessary
and effective component of the MWDOC's programs to provide a reliable supply
of water to meet the needs of MWDOC's 28 -member agencies, including the City
of Tustin. The MWDOC's Urban Water Management Plan also includes a chapter
contingency analysis of actions to be taken in response to water supply shortages.
This ordinance is consistent with the MWDOC's Urban Water Management Plan
and Water Shortage Contingency Plan.
J. The imported water supplies for Tustin and at MWDOC are subject to the Water
Shortage Allocations determined by the Metropolitan Water District of Southern
California. Subsequently, when triggered, MWDOC as a wholesaler of
Metropolitan's supplies will be required to curtail deliveries of imported water based
on MWDOC's Water Shortage Allocation Plan, which from time to time in the future
is expected to be activated when in a state of shortage.
K. All Urban Water Suppliers including the City of Tustin are required to prepare an
Annual Water Supply and Demand Assessment and Drought Risk Assessment as
part of their Urban Water Management Plan for submission to the California
Department of Water Resources. Annually, by July 1 st of each year, beginning the
year following the adoption of the 2020 UWMP. Tustin is required to monitor,
report, communicate, and if required declare a drought level response effort, then
notify the Department of Water Resources, in order to comply with the State's
Water Code 10632.1 reporting requirements.
L. On June 1, 2021, Tustin adopted its 2020 Water Shortage Contingency Plan to
establish standards and procedures to enable implementation and enforcement of
local water shortage contingency measures. These measures align with the State
of California, Water Code Section 353 which specifies that "when the governing
body has so determined and declared the existence of an emergency condition of
water shortage within its service area, it shall thereupon adopt such regulations
and restrictions on the delivery of water and the consumption within said area of
water supplied for public use as will in the sound discretion of such governing body
conserve the water supply for the greatest public benefit with particular regard to
domestic use, sanitation, and fire protection." The State of California also directs
the City of Tustin, Water Services to adopt a water conservation program to
mitigate demands in Water Code Section 375.

M. The Bureau of Reclamation on August 16, 2021 declared an official shortage
condition due to the lowering (below 1,075 feet) level of Lake Mead. Lake Mead
will operate in a Level 1 Shortage Condition in calendar year 2022 for the first time
ever, demonstrating the severity of the drought and low reservoir conditions.
N. On October 19, 2021 Governor Newsom proclaimed a State of Emergency
declaring drought condition across the entire State of California.
O. The threat of drought conditions continue to exist in Southern California so it is vital
for the City, as an urban water supplier, and for its customers to take action to
implement permanent water use restrictions to manage this limited and vital
resource.
P. In the future, Levels 1, 2, 3, 4, 5, or 6 will be declared if one or more of the following
is found to exist:
1. An Executive Order and/or Declaration issued by the Governor requires
conservation.
2. A general local or state-wide water supply shortage due to limited
supplies.
3. Distribution or storage facilities of the Metropolitan Water District of
Southern California, the Municipal Water District of Orange County, the
East Orange County Water District, or the City of Tustin become
inadequate.
4. A major failure of the supply, storage and distribution facilities of the
Metropolitan Water District of Southern California, the Municipal Water
District of Orange County, the Orange County Water District, the East
Orange County Water District, or of the City of Tustin occurs.
Q. The conditions prevailing in the State and in the region require that available water
resources be put to maximum beneficial use to the extent to which they are
capable, and that the waste or unreasonable use, excessive runoff, or
unreasonable method of use, of water be prevented and that the conservation of
such water be encouraged with a view to the maximum reasonable and beneficial
use thereof in the interests of the people served by the City of Tustin and for the
public welfare.
SECTION 2. CEQA Exemption. The City Council of the City of Tustin finds that this
Ordinance and actions taken pursuant to this Ordinance are exempt from the
California Environmental Quality Act as specific actions necessary to prevent or
mitigate an emergency pursuant to Public Resources Code Section 21080(b)(4)

Tustin 2020 Water Shortage Contingency Plan
INTRODUCTION ANS' WSCP OVERVIEW
The Water Shortage Contingency Plan (WSCP) is a strategic planning document designed to prepare for
and respond to water shortages. This WSCP complies with California Water Code (Water Code) Section
10632, which requires that every urban water supplier (Supplier) shall prepare and adopt a WSCP as part
of its Urban Water Management Plan (UWMP). This level of detailed planning and preparation is intended
to help maintain reliable supplies and reduce the impacts of supply interruptions.
The WSCP is the City of Tustin (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.

Organization
The WSCP provides the steps and water shortage response actions to be taken in times of water
shortage conditions. The WSCP has prescriptive elements, such as an analysis of water supply reliability;
the water shortage response actions for each of the six standard water shortage levels that correspond to
water shortage percentages ranging from 10% to greater than 50%; an estimate of potential to close
supply gap for each measure; protocols and procedures to communicate identified actions for any current
or predicted water shortage conditions; procedures for an Annual Assessment; monitoring and reporting
requirements to determine customer compliance; and reevaluation and improvement procedures for
evaluating the WSCP.
This WSCP is organized into three main sections, with Section 3 aligned with the Water Code Section
16032 requirements.
Section 1 Introduction and WSCP Overview gives an overview of the WSCP fundamentals.

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 State of California for SWP supplies. Member agencies receive
water from MET through various delivery points and pay for service through a rate structure made up of
volumetric rates, capacity charges and readiness to serve charges. Member agencies provide estimates
of imported water demand to MET annually in April regarding the amount of water they anticipate they will
need to meet their demands for the next five years.
The Municipal Water District of Orange County: 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.
EOCWD 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. The City receives imported water from
EOCWD via MWDOC.

Tustin 2020 Water Shortage Contingency Plan
Relationshin 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 (Stages 1-3).
• Severe Shortage: MET can meet full-service demands only by making withdrawals from storage,
calling on its water transfers, and possibly calling for extraordinary conservation and reducing
deliveries under the Interim Agricultural Water Program (IAWP) (Stages 4-5).
• Extreme Shortage: MET must allocate available imported supplies to full-service customers (Stage
6).
There are six shortage management stages to guide resource management activities. These stages are
defined by shortfalls in imported supply and water balances in MET's storage programs. When MET must
make net withdrawals from storage to meet demands, it is considered to be in a shortage condition.
Figure 2-3 gives a summary of actions under each surplus and shortage stages when an allocation plan
is necessary to enforce mandatory cutbacks. The goal of the WSDM plan is to avoid Stage 6, an extreme
shortage (MET, 1999).

MET's Board of Directors adopted a Water Supply Condition Framework in June 2008 in order to
communicate the urgency of the region's water supply situation and the need for further water
conservation practices. The framework has four conditions, each calling increasing levels of conservation.
Descriptions for each of the four conditions are listed below:
• Baseline Water Use Efficiency: Ongoing conservation, outreach, and recycling programs to achieve
permanent reductions in water use and build storage reserves.
• Condition 1 Water Supply Watch: Local agency voluntary dry -year conservation measures and use of
regional storage reserves.
• Condition 2 Water Supply Alert: Regional call for cities, counties, member agencies, and retail water
agencies to implement extraordinary conservation through drought ordinances and other measures to
mitigate use of storage reserves.
• Condition 3 Water Supply Allocation: Implement MET's WSAP.
As noted in Condition 3, should supplies become limited to the point where imported water demands
cannot be met, MET will allocate water through the WSAP (MET, 2021 a).
2.3.2 MET Water Supply Allocation Plan
MET's imported supplies have been impacted by a number of water supply challenges as noted earlier. In
case of extreme water shortage within the MET service area is the implementation of its WSAP.
2-6
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 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, 2021 a).
The WSAP includes the specific formula for calculating member agency supply allocations and the key
implementation elements needed for administering an allocation. MET's WSAP is the foundation for the
urban water shortage contingency analysis required under Water Code Section 10632 and is part of
MET's 2020 UWMP.
MET's WSAP was developed in consideration of the principles and guidelines in MET's 1999 WSDM Plan
with the core objective of creating an equitable "needs -based allocation." The WSAP's formula seeks to
balance the impacts of a shortage at the retail level while maintaining equity on the wholesale level for
shortages of MET supplies of greater than 50% cutbacks. 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).

Tustin 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

Tustin 2020 Water Shortage Contingency Plan
according to the retail agency's prorated share (AF over usage) of MWDOC amount with MET.
Surcharge funds collected by MET will be invested in its Water Management Fund, which is used to
in part to fund expenditures in dry -year conservation and local resource development.
Tracking and Reporting Water Usage — MWDOC will provide each retail agency with water use
monthly reports that will compare each retail agency's current cumulative retail usage to their
allocation baseline. MWDOC will also provide quarterly reports on its cumulative retail usage versus
its allocation baseline.
• Timeline and Option to Revisit the Plan — The allocation period will cover 12 consecutive months
and the Regional Shortage Level will be set for the entire allocation period. MWDOC only anticipates
calling for allocation when MET declares a shortage; and no later than 30 days from MET's
declaration will MWDOC announce allocation to its retail agencies.

11 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 (Tustin, 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 drought supplies from
EOCWD/MWDOC/MET and ongoing conservation program efforts. The City has also added reliability through
receiving the majority of its water supply from groundwater from the OC Basin and supplemental supplies from
EOCWD/MWDOC/MET. As a result, there is no projected shortage condition due to drought that will trigger
customer demand reduction actions until MWDOC and/or EOCWD notifies the City of insufficient imported
supplies. More information is available in the City's 2020 UWMP (Tustin, 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.

Tustin 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 receives groundwater from OCWD. The OC Basin is not adjudicated and as such, pumping from the OC
Basin is managed through a process that uses financial incentives to encourage groundwater producers
(Producers) to pump a sustainable amount of water. The framework for the financial incentives is based on
establishing the BPP, the percentage of each Producer's total water supply that comes from groundwater pumped
from the OC Basin. The BPP is set uniformly for all Producers by OCWD on an annual basis 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 EOCWD/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

The City Manager and/or his or her designated representative shall review the Annual Assessments from MET,
MWDOC, and OCWD and incorporate the finding into the City's assessment. The City Manager and/or his or her
designee will authorize the City's Annual Assessment determining specific shortage response action necessary to
prudently plan for water supply needs to its customers, and/or or comply with regulations and/or restrictions
implemented by the State Water Resources Control Board (SWRCB), MET, MWDOC, or OCWD. The City will
formally submit assessment findings 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, EOCWD/MWDOC imported water supplies, planned water use, and infrastructure
considerations. The balance between projected local supplies coupled with MET 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 EOCWD. 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 FY 2019-20, the City
relied on 96% groundwater and 4% imported water. It is projected that by 2045, the water supply mix will change
RM
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
to approximately 85% groundwater and 15% imported water, reflecting the increase in OCWD's BPP to 85%
beginning in 2025 (Tustin, 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 (Tustin, 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 State of Emergency citing 2014 as the driest year in California history. Additionally, within
MWDOC's service area, precipitation for FY 2013-14 was the second lowest on record, with 4.37 inches of rain,
significantly impacting water demands.
The water demand forecasting model developed for the Demand Forecast TM isolated the impacts that weather
and future climate can have on water demand through the use of a statistical model. The impacts of hot/dry
weather conditions 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 conservation (Tustin, 2021).

Tustin 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.
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
The City has 5 wells impacted by PFAS. PFAS are of particular concern for groundwater quality, and since the
summer of 2019, DDW requires testing for PFAS compounds in some groundwater production wells in the OCWD
area. In February 2020, the DDW lowered its Response Levels (RL) for PFOA and PFOS to 10 and 40 parts per
trillion (ppt), respectively. The DDW recommends Producers not serve any water exceeding the RL — effectively
making the RL an interim Maximum Contaminant Level (MCL) while DDW undertakes administrative action to set
a MCL. In response to DDW's issuance of the revised RL, as of December 2020, approximately 45 wells in the
OCWD service area have been temporarily turned off until treatment systems can be constructed. As additional
wells are tested, OCWD expects this figure may increase to at least 70 to 80 wells. The state has begun the
process of establishing MCLS for PFOA and PFOS and anticipates these MCLS to be in effect by the Fall of 2023.
OCWD anticipates the MCLS will be set at or below the RLs.
In April 2020, OCWD as the groundwater basin manager, executed an agreement with the impacted Producers to
fund and construct the necessary treatment systems for production wells impacted by PFAS compounds. The
PFAS treatment projects includes the design, permitting, construction, and operation of PFAS removal systems
for impacted Producer production wells. Each well treatment system will be evaluated for use with either granular
activated carbon or ion exchange for the removal of PFAS compounds. These treatment systems utilize vessels
in a lead -lag configuration to remove PFOA and PFOS to less than 2 ppt (the current non -detect limit). Use of
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
W.
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
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).
Six Standard Water Shortaqe 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:
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 the actions will reduce the gap between supplies and demands to deliver the
outcomes necessary to meet the requirements of a given shortage level. This table also identifies the
enforcement action, if any, associated with each demand reduction measure.
3.4.2 Supply Augmentation
The supply augmentation actions are described in DWR Table 8-3 (Appendix A). These augmentations represent
short-term management objectives triggered by the MET's WSDM Plan and do not overlap with the long-term new
water supply development or supply reliability enhancement projects. Supply Augmentation is made available to
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
me
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
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; however the City is limited by groundwater pumping approvals.
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 Tustin Municipal Code Chapter 10 Water Management Plan (Appendix B). The City intends
to update any mandatory restrictions in a subsequently adopted ordinance with 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 WDSM and WSAP and the Water
Emergency Response Organization of Orange County (WEROC)'s Emergency Operations Plan (EOP).
3.4.5.1 MET's WSDM and WSAP
MET has comprehensive plans for stages of actions it would undertake to address a catastrophic interruption in
water supplies through its WSDM and WSAP. MET also developed an Emergency Storage Requirement to
mitigate against potential interruption in water supplies resulting from catastrophic occurrences within the
Southern California region, including seismic events along the San Andreas Fault. In addition, MET is working
with the state to implement a comprehensive improvement plan to address catastrophic occurrences outside of
the Southern California region, such as a maximum probable seismic event in the Sacramento -San Joaquin River
Delta that would cause levee failure and disruption of SWP deliveries.
3.4.5.2 Water Emergency Response Organization of Orange County Emergency
Operations Plan
In 1983, the Orange County water community identified a need to develop a plan on how agencies would respond
effectively to disasters impacting the regional water distribution system. The collective efforts of these agencies
resulted in the formation of WEROC to coordinate emergency response on behalf of all Orange County water and
3-10
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
wastewater agencies, develop an emergency plan to respond to disasters, and conduct disaster training
exercises for the Orange County water community. WEROC was established with the creation of an
indemnification agreement between its member agencies to protect each other against civil liabilities and to
facilitate the exchange of resources. WEROC is unique in its ability to provide a single point of contact for
representation of all water and wastewater utilities in Orange County during a disaster. This representation is to
the county, state, and federal disaster coordination agencies. Within the Orange County Operational Area,
WEROC is the recognized contact for emergency response for the water community, including the City.
As a member of WEROC, the City will follow WEROC's EOP in the event of an emergency and coordinate with
WEROC to assess damage, initiate repairs, and request and coordinate mutual aid resources in the event that the
City is unable to provide the level of emergency response support required by the situation.
The EOP defines the actions to be taken by WEROC Emergency Operations Center (EOC) staff to reduce the
loss of water and wastewater infrastructure; to respond effectively to a disaster; and to coordinate recovery
operations in the aftermath of any emergency involving extensive damage to Orange County water and
wastewater utilities. The EOP includes activation notification protocol that will be used to contact partner agencies
to inform them of the situation, activation status of the EOC, known damage or impacts, or resource needs. The
EOP is a standalone document that is reviewed annually and approved by the Board every three years.
WEROC is organized on the basis that each member agency is responsible for developing its own EOP in
accordance with the California Standardized Emergency Management System (SEMS), National Incident
Management System (NIMS), and Public Health Security and Bioterrorism Preparedness and Response Act of
2002 to meet specific emergency needs within its service area.
The WEROC EOC is responsible for assessing the overall condition and status of the Orange County regional
water distribution and wastewater collection systems including MET facilities that serve Orange County.
The EOC can be activated during an emergency situation that can result from both natural and man-made
causes, and can be activated through automatic, manual, or standby for activation.
WEROC recognized four primary phases of emergency management, which include
• Preparedness: Planning, training, and exercises that are conducted prior to an emergency to support
and enhance response to an emergency or disaster.
• Response: Activities and programs designed to address the immediate and short-term effects of the
onset of an emergency or disaster that helps to reduce effects to water infrastructure and speed recovery.
This includes alert and notification, EOC activation, direction and control, and mutual aid.
• 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).

Tustin 2020 Water Shortage Contingency Plan
3.4.5.3 City of Tustin's 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 (Tustin, 2020).
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
of aqueducts, pipelines and other facilities associated with delivering the supplies to the region. Additionally, the
infrastructure in place to deliver supplies are susceptible to damage from earthquakes and other disasters.
In lieu of conducting a seismic risk assessment specific to the City's 2020 UWMP, the City has included the
previously prepared regional HMP by MWDOC as the regional imported water wholesaler that is required under
the federal Disaster Mitigation Act of 2000 (Public Law 106-390).
MWDOC's HMP identified that the overarching goals of the HMP were the same for all of its member agencies,
which include:
• Goal 1: Minimize vulnerabilities of critical infrastructure to minimize damages and loss of life and injury to
human life caused by hazards.
• Goal 2: Minimize security risks to water and wastewater infrastructure.
• Goal 3: Minimize interruption to water and wastewater utilities.
• Goal 4: Improve public outreach, awareness, education, and preparedness for hazards in order to
increase community resilience.
• Goal 5: Eliminate or minimize wastewater spills and overflows.
• Goal 6: Protect water quality and supply, critical aquatic resources, and habitat to ensure a safe water
supply.
• Goal 7: Strengthen Emergency Response Services to ensure preparedness, response, and recovery
during any major or multi -hazard event.
MWDOC's HMP evaluates hazards applicable to all jurisdictions in its entire planning area, prioritized based on
probability, location, maximum probable extent, and secondary impacts. The identification of hazards is highly
dependent on the location of facilities within the City's jurisdiction and takes into consideration the history of the
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
3-12
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
County will continue to experience future earthquake events, and it is a reasonable assumption that a major event
will occur within a 30 -year timeframe.
The mitigation actions identify the hazard, proposed mitigation action, location/facility, local planning mechanism,
risk, cost, timeframe, possible funding sources, status, and status rationale, as applicable. Mitigation actions for
MWDOC's member agencies for seismic risks may include (MWDOC, 2019):
• Secure above ground assets in all buildings, booster stations, pressure reducing stations, emergency
interties, water systems, and pipelines.
• Conduct assessment of infrastructure to ensure seismic retrofitting is in place.
• Replace aging infrastructure throughout the City.
• Install backup power for critical facilities to ensure operability during emergency events.
• Enhance emergency operability by implementing communication infrastructure improvements.
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, City has estimated percentage savings for the chosen suite of shortage response actions, which
can be anticipated to deliver the expected outcomes necessary to meet the requirements of a given shortage
level.
3.5 Communication Protocols
Timely and effective communication is a key element of the WSCP implementation. In the context of water
shortage response, the purpose may be an emergency water shortage situation, such as may result from an
earthquake, or a longer-term, non -emergency, shortage condition, such as may result from a drought. In an
emergency, the City will activate the communication protocol detailed in the Emergency Response Plan. In a non-
emergency water shortage situation, the City will implement the communication protocols described below.
Per the Water Code Section 10632 (a)(5), the City has established communication protocols and procedures to
inform customers, the public, interested parties, and local, regional, and state governments regarding any current
or predicted shortages as determined by the Annual Assessment described pursuant to Section 10632.1; any
shortage response actions triggered or anticipated to be triggered by the annual water supply and demand
assessment described pursuant to Section 10632.1; and any other relevant communications.
Non -emergency water shortage communication protocols are focused on communicating the water shortage
contingency planning actions that can be derived from the results of the Annual Assessment, and it would likely
trigger based upon the decision-making process in Section 3.2. Prior to water shortage level declaration, the City
will pursue outreach to inform customers of water shortage levels and definitions, targeted water savings for each
drought stage, guidelines that customers are to follow during each stage, and sources of current information on
the City's supply and demand response status.
The type and degree of communication will vary with each shortage level in order to inform stakeholders of the
current water shortage level status and associated shortage response actions, as defined in Section 3.4.1.
Predefined communication objectives and tools will ensure the City's ability to message necessary events and
information to ensure compliance with shortage response actions. These communication objectives and tools are
summarized in Table 3-2.

The City's Public Relations department will lead public information and outreach efforts in close coordination with
other MWDOC and MET. The City will share information and provide guidance to its customers as well as monitor
the customer response and attitude toward both voluntary and mandatory customer response guidelines. The
City's customer outreach is required to successfully achieve targeted water savings during each shortage level.

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 and customer enforcement, appeal, and exemption procedures as defined in the existing
Tustin Municipal Code Chapter 10 Water Management Plan (Appendix B). The City intends to update any
enforcement procedures in a subsequently adopted ordinance which will supersede the existing ordinance.
3. / —egcil /AUif UIr111e5
Per Water Code Section 10632 (a)(7)(A), the City has provided a description of the legal authorities that empower
the City to implement and enforce its shortage response in the Tustin Municipal Code Chapter 10 Water
Management Plan (Appendix B). The City intends to update any legal authorities in a subsequently adopted
ordinance which will supersede the existing ordinance.
Per Water Code Section 10632 (a)(7) (B), the City shall declare a water shortage emergency condition to prevail
within the area served by such wholesaler whenever it finds and determines that the ordinary demands and
requirements of water consumers cannot be satisfied without depleting the water supply of the distributor to the
extent that there would be insufficient water for human consumption, sanitation, and fire protection.
Per Water Code Section 10632 (a)(7)(C), the City shall coordinate with any agency or county within which it
provides water supply services for the possible proclamation of a local emergency under California Government
Code, California Emergency Services Act (Article 2, Section 8558). Table 3-3 identifies the contacts for all cities
or counties for which the Supplier provides service in the WSCP, along with developed coordination protocols,
can facilitate compliance with this section of the Water Code in the event of a local emergency as defined in
subpart (c) of Government Code Section 8558.

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.
3-15
DocuSign Envelope ID: 89AB5F7E-7024-41 E5-8A70-595E64F5D32A
Tustin 2020 Water Shortage Contingency Plan
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 10 Water Management Plan (Appendix B).
However, there are significant fixed costs associated with maintaining a minimal level of service. The City will
monitor projected revenues and expenditures should an extreme shortage and a large reduction in water sales
occur for an extended period of time. To overcome these potential revenue losses and/or expenditure impacts,
the City may use reserves. If necessary, the City may reduce expenditures by delaying implementation of its
Capital Improvement Program and equipment purchases to reallocate funds to cover the cost of operations and
critical maintenance, adjust the work force, implement a drought surcharge, and/or make adjustments to its water
rate structure.
Based on current water rates, a volumetric cutback of 50% and above of water sales may lead to a range of
reduction in revenues. The impacts to revenues will depend on a proportionate reduction in variable costs related
to supply, pumping, and treatment for the specific shortage event. The City has set aside reserve funding 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, 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.

Tustin 2020 Water Shortage Contingency Plan
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
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 Tustin Municipal Code Chapter 10 Water
Management Plan (Appendix B).
3.1; 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 in advance of the public
hearing on June 1, 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 C.
The City held the public hearing for the draft 2020 UWMP and draft WSCP on June 1, 2021 at the City Council
meeting. The City Council reviewed and approved the 2020 UWMP and the WSCP at its June 1, 2021 meeting
after the public hearing. See Appendix D for the resolution approving the WSCP.
