MWD’s supply mix. To address potential impacts to Colorado River supplies, Water Authority and MWD have implemented a number of conservation, land fallowing, transfer, and storage projects.

Both the SWP and the Colorado River are described in the Water Authority and MWD 2025 UWMPs.

Threats to Infrastructure
Imported supplies conveyed through DWR’s California Aqueduct (SWP water) and MWD’s Colorado River Aqueduct must travel across large distances to reach turnouts where local agencies can access the water. California is a seismically active state and prone to wildfires, which could damage imported water infrastructure anywhere along the SWP or Colorado River Aqueduct in such a manner as to disrupt supply availability. California is also a large state with a large economy, housing major industries and defense installations. This makes it a potential target for acts of terrorism, including potential threats to its water supplies and infrastructure.

Water Quality
Water quality challenges, such as salinity, algae toxins, disinfection byproduct precursors, nutrients, and the identification of constituents of emerging concern can impact imported water supplies.

Poor water quality can result in higher treatment costs to reliably treat water to meet drinking water standards. To date, the Water Authority has not identified any water quality risks that cannot be mitigated. Salinity, particularly in Colorado River supplies, is a significant issue, but MWD anticipates the only constraint will be the need to blend Colorado River water with SWP supplies to meet salinity needs. The Water Authority is committed to protecting water quality in its system and communicates water quality changes to the City to ensure the water quality is protected.

Constraint on SLRIWA Supply
The City obtains water from the SLRIWA Settlement Agreement. Under the Settlement Agreement, the United States agrees to deliver up to 16,000 AFY of supplemental water to the Indian Bands, the City, and VID. The City and VID each have the right to remove equal amounts of water each calendar year. For this analysis, it was assumed that the City is limited to 7,900 AFY. Water from the SLRIWA is conveyed through infrastructure owned and operated by MWD and the Water Authority. As such, any factors that may affect the Water Authority impacts the SLRIWA water supply.

Year Type Characterization
Historically, the Water Authority supply has been reliable with only occasional reductions during droughts in California or the Colorado River system. Table 7-1 shows the basis of water year data used to understand demand response in the City’s service area. The supply reliability assessment is based on data provided in Water Authority’s 2025 UWMP, Chapter 9 Water Supply Reliability. Due to their very high priority water rights, Water Authority’s Colorado River supplies of conserved water from its IID transfer and the All-American and Coachella Canal Lining projects are considered to be drought resilient. For dry year analysis, Water Authority assumes that the MWD supplies will be allocated according to its preferential right formula. With these supplies, Water Authority projects no shortages to its member agencies during the normal, single, and multiple dry year scenarios. Any shortages that might occur would be handled through the use of Water Authority’s dry year supplies and carry-over storage program, described in Section 11.4 of the Water Authority 2025 UWMP, which includes both in-region surface water storage and out-of-region groundwater storage in California’s Central Valley. The carryover storage capacity is approximately 100,000 AF in Resolution No. 2026-67

the San Vicente Reservoir and 70,000 AF in the Semitropic-Rosamond Water Bank Authority and the Semitropic Water Bank in Kern County.

The water service reliability and DRA analyze supply over several water years: normal, single dry, and five consecutive dry years.

DWR defines these years as:
 Normal (Average) Year. This represents the water supplies a supplier considers available during normal conditions.
 Single Dry Year. The single dry year is recommended to be the year that represents the lowest water supply available.
 Multiple Dry Years. The driest five-year historical sequence for the supplier, which may be the lowest average water supply available for five years in a row.

As the City’s water demand has consistently decreased over the time period used for the assessment, the data was normalized to more accurately assess changes due to drought rather than other factors such as population decline.

7.1.2 Water Service Reliability
Normal demand and supply projections were developed in Chapter 4 and Chapter 6 and form the basis of this reliability analysis.

The Water Authority has determined that it will be able to meet the City’s potable demands, during normal, single dry and multiple dry year conditions through 2050. If needed due to demand response in hot/dry conditions, it is anticipated that the City will be able to purchase additional supply from the Water Authority to meet its potable demands.

In the Water Authority’s 2025 reliability assessment, the Water Authority assumed that the projected supplies from MWD were supplemental and calculated as the increment of supply necessary to meet demands after considering member agency verifiable sources and the Water Authority’s core supplies. The Water Authority defined “verifiable” as projects with substantial evidence and adequate documentation regarding implementation and use. The Water Authority considers the City’s surface water, SLRIWA, MFRO, and HARRF recycled water supplies as verifiable.

Water Service Reliability – Normal Year
The Water Authority’s normal and dry year assessments of supplies and demands are based upon its Quantification Settlement Agreement supplies and seawater desalination supplies totaling 319,700 Resolution No. 2026-67

AFY, as well as the Water Authority’s Preferential Right to Metropolitan supplies under Section 135 of the Metropolitan Act, which vary by normal or dry-year condition. If MWD, Water Authority, and the City’s supplies are developed as planned, along with achievement of its urban water use objective, no shortages are anticipated within Water Authority’s service area in a normal year through 2050. As part of preparation of its 2025 UWMP, the Water Authority identified the City’s demands and in turn, MWD identified the Water Authority’s demands in MWD’s UWMP, which are shown to be adequate to cover the demands for the entire San Diego region, including the City. If the supplies do not develop as planned, Water Authority’s UWMP Chapter 10 Scenario Planning— Managing an Uncertain Future provides scenario planning to address any shortages and is summarized in Section 7.5.

The projected supply and demand comparison under normal water year conditions is shown in Table 7-2. Under normal conditions, the City will first meet potable demands using local surface water and SLRIWA imported water prior to purchasing water from the Water Authority. The “Imported Supplies – Water Authority” is the anticipated demand on the Water Authority after the City’s other supplies are consumed.

The City’s normal year supply forecast assumes that no WSCP measures would be implemented.

Water Service Reliability – Single Dry Year
The Water Authority’s single dry year assessment includes projected demands that reflect long-term water use efficiency, but do not incorporate potential savings due to extraordinary conservation occurring during droughts. Projected local groundwater and surface water yields were based on an average of dry-year (2013, 2018, and 2021) totals. Water Authority member agencies projected verifiable supplies for recycling, potable reuse, seawater desalination, groundwater recovery, and water transfers were assumed to experience little, if any reduction in a dry year. The Water Authority’s Quantification Settlement Agreement supplies and its seawater desalination supplies are also considered drought resilient. The Water Authority assumed MWD supplies were limited to a historically low 1.3 MAF due to dry conditions and additional reductions would occur in MWD’s deliveries from the SWP (i.e., no Delta improvements) and Colorado River, and that the Water Authority received its Preferential Right based on MWD’s current method of calculating such rights.

Water Service Reliability and Drought Risk Assessment

Public Review Draft 7-7
To estimate single dry year demand projections, the City developed a demand response index formula to identify demand response in historical, low-rainfall years. The City’s single dry year demand forecast assumed an eight percent increase from normal demand. While this is greater than the regional average that the Water Authority used in its single dry demand forecast, the Water Authority’s supply assessment shows well over 370,000 AFY of potential surplus supplies even without utilization of carryover storage. With a conservative assumption regarding limited MWD supplies during a single dry-year, the Water Authority and member agency supplies maintained and developed as planned, and the achievement of the additional conservation targets, no shortages are anticipated in the Water Authority service area under single dry-year conditions.

Table 7-3 shows the City’s single dry year assessment through 2050. The City assumes that the WSCP would not typically be implemented in a single dry year.

Water Service Reliability – Five Consecutive Dry Years
To estimate demands for five consecutive dry years, the percentage of total demand on the Water Authority in multiple dry years compared to a normal year was applied to adjust for typical demand response during long-term dry periods, along with customer behavioral changes in response to WSCP actions. Table 7-5 presents the City’s five-consecutive year drought assessment through 2050.

To estimate multiple dry year demand projections, the City’s demand forecast assumed an eight percent increase from normal demand in year one, 11 percent in year two, 14 percent increase in year three, 17 percent increase in year 4, and 20 percent increase in year five. In response to drought conditions and activation of the WSCP in year two, demand response was then reduced by six percent in each consecutive year. The Water Authority’s supply assessment shows well over 250,000 AFY of potential surplus supplies even without utilization of carryover storage. With a conservative assumption regarding limited MWD supplies, the Water Authority and member agency supplies maintained and developed as planned, and the achievement of the additional conservation targets, no shortages are anticipated in the Water Authority service area under multiple dry year conditions.

7.1.3 Descriptions of Management Tools and Options
In 2025 the City obtained 86% of its water from the Water Authority via the SLRIWA or purchased raw water. The City will continue to promote conservation behaviors that may offset imported water needs. Should a water shortage occur, the City may implement the WSCP, included in Appendix A, to address any shortage conditions and reduce demands.

7.2 Drought Risk Assessment
Water Code Section 10635 (b) requires a Drought Risk Assessment (DRA) which provides a snapshot of the anticipated surplus or deficit if a five-consecutive year drought were to occur within the next five years. The DRA evaluates each water supply’s reliability and compares available water supplies Resolution No. 2026-67

and projected demands during a five-consecutive dry years scenario. This short-term analysis can help water suppliers foresee undesired risks, such as upcoming shortages, and provide time to evaluate and implement the necessary response actions needed to mitigate shortages in a less impactful manner to the community and environment. If demands cannot be met by the expected available supply, shortage response actions from the City’s WSCP may be implemented. Details on the City’s WSCP are provided in Appendix A.

7.2.1 Data, Methods, and Basis for Water Shortage Condition Over the last few decades, the City has diversified its water supply portfolio, increasing production and use of local supplies and reducing dependance on the Water Authority. Since the City receives a larger portion of its water supply from the Water Authority, however, the following DRA reflects the analysis in Section 9 of the Water Authority’s UWMP (Water Authority, 2026).

The Water Authority used the historical period of 2014 through 2018 to represent the driest consecutive five-year period. Years 2014 through 2018 represents the five-year period with the lowest local water supply production from surface water and groundwater, the two local water supplies that are most susceptible to weather variation. Over that period, the combined annual production from those two sources ranged from a low of 21,245 AF to a high of 67,374 AF. The Water Authority showed no reduction in availability over the five-year period for regional supplies.

The data used to calculate the Water Authority’s supply capabilities under the scenario of five consecutive dry years is shown in Chapter 9 of the Water Authority’s 2025 UWMP. For each year, a comparison was made between available water supplies and water demands. For the Water Authority supplies which consist of Quantification Settlement Agreement supplies and seawater desalination, no reduction in the availability over the five-year period is assumed due to the drought resilience of these supplies. For the Water Authority member agency supplies, only surface water and groundwater are considered to be susceptible to variations in weather. The volume of those supplies varies over the five-year period based on actual production from 2011 to 2015. For MWD supplies, the volume of water for each year is based on the Water Authority preferential right to MWD purchases.

Demands over the next five years were estimated by starting with 2025 demands and applying the escalation multipliers discussed in the previous section for the multiple dry year scenario. Table 7-5 shows these demand multipliers compared to the demand multipliers developed by the Water Authority, which are based on a weather index used to assess the impact of dry/hot weather on water demands. Specifically, the index used for the Water Authority’s demand multipliers was constructed from weather parameters of the water demand forecasting models and used to determine the multipliers for consecutive dry/hot weather (Water Authority, 2026). Table 7-5 additionally compares the projected City demands for 2021 through 2025 with the demands projected using the Water Authority’s demand multipliers. Although the City used greater demand multipliers, the projected demand totals assume the implementation of the City’s WSCP, and thus the Water Authority’s projected demands are higher than the City’s.

7.2.2 Water Source Reliability
The City does not anticipate any supply shortages within the next five years as shown in Table 7-6.

The Water Authority’s DRA concluded that the Water Authority has a surplus of supplies in all five years and, therefore, actions under the WSCP are not required. Similarly, because of the Water Authority’s analysis and large amounts of surplus, the City does not expect any water supply shortages. As the City’s assumptions for demand increase in a multi-year dry period are greater than the Water Authority’s, the City assumes actions under the WSCP will be implemented beginning in the second year of a multi-year dry period (2027 for the 2026-2030 drought risk assessment).

7.3 San Diego County Water Authority Scenario
Planning - Managing an Uncertain Future
The Water Authority 2025 UWMP Section 10 describes their planning for four scenarios as a way to address managing an uncertain future:

1. Drought with Local Supplies Implemented as Planned

2. Drought with Local Supply Projects Delayed

3. Drought Post IID Transfer Agreement Expiration

4. Climate Change
For scenarios one through three, the Water Authority concluded that they had surplus supplies to meet demands as long as the supplies are developed as planned. Relative to Scenario 4, since there are many uncertainties regarding the impact of climate change on water supply and demand, Water Authority conducted a qualitative risk assessment. The Water Authority concluded that climate change could result in a long-term decrease in the availability of imported and local supplies, causing a potential gap between supply and demand. In addition, supply and demand impacts from climate change have already occurred and will continue to be experienced within the 2025 UWMP 25-year planning horizon.

The Water Authority 2025 UWMP concludes that its scenario evaluation demonstrates that the San Diego region is well positioned to maintain a safe, reliable water supply across the planning horizon—even under extreme conditions. This conclusion reflects decades of work to assemble a diversified, drought-resilient portfolio that includes member-agency verifiable projects and long- term efficiency, Quantification Settlement Agreement supplies, seawater desalination, and MWD supplies.

8.1 Setting
The WSCP describes how the City intends to predict and respond to foreseeable and unforeseeable water shortages, which occur when available water supplies are reduced to a level that cannot support typical demand at any given time. The WSCP serves as a planning document to guide the City Council, staff, and the public by identifying response actions that allow for efficient and accountable management of water shortages with predictability and transparency. While the WSCP does not provide absolute direction, it offers a range of response options to address varying water shortage conditions.

Water shortages may be triggered by hydrologic limitations in supply—such as prolonged periods of below-normal precipitation and runoff—failures or limitations in supply or treatment infrastructure, or a combination of both. Hydrologic or drought-related shortages typically develop and subside gradually, whereas infrastructure-related shortages tend to occur more suddenly and unpredictably.

Water supplies may be interrupted or substantially reduced due to events such as drought, earthquakes that damage delivery or storage facilities, regional power outages, or toxic spills that affect water quality.

Since the City’s 2020 UWMP, several Executive Orders have been issued by the state in response to prolonged drought conditions shaping water management requirements for urban water suppliers.  March 2022, Executive Order N-7-22: marked a statewide drought response requiring urban water suppliers to implement Stage 2 WSCP actions, representing approximately a 20 percent supply reduction, and submit preliminary and final water supply and demand assessments by June 1 and July 1, 2022. The order also directed the State Water Board to prohibit irrigation of non-functional turf in commercial, industrial, and institutional landscapes. Suppliers without approved WSCPs were subject to default plans, reinforcing the urgency of conservation and compliance.
 February 2023, Executive Order N-3-23: extended statewide drought emergency provisions, emphasizing climate uncertainty and the need for preparedness. The order supported ongoing conservation efforts and streamlined permitting for groundwater and recharge projects, reflecting a shift from mandatory restrictions toward long-term resilience planning.  March 2023, Executive Order N-5-23: ended the statewide requirement for Stage 2 WSCP actions. Urban water suppliers, including the City, were permitted to return to Stage 1 or lower response levels, and emergency regulations requiring Level 2 actions expired on June 10, 2023.  September 2024: a phased rollback of drought emergency provisions was lifted in 19 counties, which included major urban areas within San Diego County, including the City to return to voluntary conservation while continuing to monitor local supply conditions. In compliance with Executive Order N-7-22, the City implemented prohibitions on nonessential water use, conducted public outreach and enforcement, and reported water use data as required during the emergency period.

8.2 Water Supply Reliability Assessment
The Water Supply Reliability Assessment in Chapter 7 of this 2025 UWMP evaluates the City’s ability to meet customer demands under normal, single-dry, and multiple dry-year conditions. The analysis confirms that the City’s water supply is predominantly sourced from the Water Authority, with additional support from local reservoirs and transfers from the SLRIWA. Based on UWMP projections through 2045, no shortages are anticipated even under conservative assumptions, ensuring long-term reliability. A five-year Drought Risk Assessment (DRA), also in Chapter 7 of this 2025 UWMP, using the driest historical period from 2014 to 2018 further indicates that the City expects no supply deficits due to surplus allocations from Water Authority. While the system is robust, potential reliability risks remain, including climate change impacts, infrastructure failures, and catastrophic events, which are addressed through contingency measures and adaptive planning strategies detailed in the WSCP’s Appendix A.

8.3 Annual Water Supply and Demand Assessment
The City performs an annual assessment of water supply and demand to determine whether shortage conditions exist and if activation of a WSCP stage is necessary. This assessment is a statutory requirement under CWC Section 10632 and is designed to provide a short-term outlook on water reliability for the upcoming year.

Water Shortage Contingency Plan

Public Review Draft 8-3
A key feature of this process is the City’s dependency on the Water Authority. Since the majority of the City’s water supply is imported through Water Authority, the City’s annual assessment, performed every March through June, is closely tied to Water Authority’s annual assessment. Water Authority first reviews its core water sources and member agency demands, determines if a regional shortage exists, and considers mitigation measures such as using stored reserves or supply augmentation. If Water Authority identifies a shortfall, it calculates the regional shortage level and informs member agencies, including the City of Escondido, of any required demand reductions or allocation limits. The City then incorporates this information into its own assessment, alongside local supply and demand data, to finalize its determination of shortage conditions. More detailed information for evaluation criteria for current demand, available supply, infrastructure constraints, and regulatory mandates analysis can be found in the WSCP’s Appendix A.

8.4 Six Standard Water Shortage Levels
The adoption of six standardized water shortage levels provides a consistent statewide framework for declaring shortages and implementing response actions. This approach ensures uniformity across California, making it easier for agencies, regulators, and the public to understand and respond to water shortage conditions.

Under CWC Section 10632(a)(2), urban water suppliers must define shortage levels corresponding to progressive ranges of supply reductions:
up to 10%, 20%, 30%, 40%, 50%, and greater than
50%. These levels are based on actual supply conditions, such as reductions in imported water, changes in groundwater levels, or other hydrologic indicators. The standardized structure allows for clear communication, predictable enforcement, and coordinated regional and statewide drought response efforts.

For the City, aligning with these six levels also ensures consistency with the Water Authority’s regional shortage stages. This alignment helps streamline planning, reporting, and compliance with state mandates while providing flexibility to implement locally-appropriate actions at each stage.

The six standard water shortage levels are reflected in Table 8-1.

8.5 Shortage Response Actions
The City’s WSCP establishes a comprehensive set of actions to address water shortages, organized into key categories to ensure flexibility and effectiveness.

8.5.1 Demand Reduction
The City emphasizes water use efficiency with its customers at all times and expands efforts during shortage stages. Actions include:
 Limiting irrigation schedules and restricting watering during rainfall events.  Prompt leak detection and repair requirements.
 Enhanced conservation outreach and education campaigns.  Implementation of drought pricing structures or surcharges to encourage reduced consumption.

These measures ensure that conservation becomes a shared responsibility, helping the community collectively reduce demand during critical periods. Demand reduction actions are described in detail in the WSCP and are highlighted below in Table 8-2.

8.5.2 Supply Augmentation
The City does not plan to develop new supply sources during shortages. Instead, it relies primarily on:
 Additional imported water through the Water Authority.  Use of regional storage reserves managed by Water Authority when available.

These measures ensure that conservation becomes a shared responsibility, helping the community collectively reduce demand during critical periods.

8.5.3 Operational Changes
Operational adjustments may be implemented to maximize efficiency and reduce demand, including:
 Reducing line flushing to essential compliance only.
 Monitoring construction water use for efficiency.
 Implementing drought rate structures or emergency tiered pricing.  Deferring non-critical capital improvement projects and major maintenance to offset financial impacts.

Such operational adjustments allow the City to optimize resources and maintain essential services while minimizing financial strain during shortages.

8.5.4 Additional Mandatory Restrictions
Permanent prohibitions apply at all times and are enforced during shortages. These include:
 Preventing irrigation runoff.
 Prohibiting non-recirculating fountains and decorative water features.  Restricting washing of hardscape surfaces except for health or safety reasons.  Requiring water-efficient systems in car washes and laundromats.

These permanent prohibitions reinforce the City’s commitment to preventing water waste and safeguarding supplies under all conditions.

8.5.5 Emergency Response Plan
In catastrophic shortage conditions, the City activates emergency protocols such as:
 Filling distribution reservoirs to capacity.
 Deploying portable generators to critical facilities.  Prioritizing repairs to maintain firefighting and health needs.  Communicating clear public guidance on allowable uses and emergency water availability.

Through proactive emergency protocols, the City can act swiftly to protect public health, safety, and essential water services during catastrophic events.

8.5.6 Seismic Risk Assessment and Mitigation Plan
The City complies with the America’s Water Infrastructure Act (AWIA) by maintaining a Risk and Resilience Assessment (RRA) and Emergency Response Plan (ERP). These plans identify vulnerabilities, address seismic risks, and outline mitigation strategies to ensure long-term system resilience. Further, the San Diego County’s 2023 Multi-Jurisdictional Hazard Mitigation Plan also addresses risk assessment and mitigation for multiple emergency types that could create a water supply interruption and can be found at
www.sandiegocounty.gov/oes/emergency_management/oes_jl_mitplan.html.

8.6 Communication Protocols
The City’s WSCP establishes a comprehensive communication framework to ensure timely and effective outreach during water shortage conditions. The primary goal is to keep customers, the public, and local officials informed about current or anticipated shortages, required conservation measures, and available resources. Further detail on these protocols is outlined in Appendix A of the WSCP.
 Coordination: During droughts or other supply limitations, the City will coordinate closely with the Water Authority and neighboring water districts to maintain consistent messaging and minimize confusion. Water Authority will lead regional outreach efforts, while the City will supplement these with Escondido-specific information as needed.  Key Audiences: The communication strategy targets all water users within the City’s service area, including customers both inside and outside city boundaries.  Objectives: Messaging will focus on motivating immediate conservation actions, raising awareness of drought or regulatory conditions affecting water supplies, and demonstrating the effectiveness of conservation measures in reducing shortage stages and protecting the region’s economy and quality of life.
 Flexibility and Adaptability: Recognizing that water shortage conditions can vary significantly, the communication plan is designed to be flexible. It provides recommended strategies and tactics for escalating shortage levels but allows staff to tailor approaches based on factors such as severity, budget, seasonal conditions, and regulatory requirements of the WSCP Appendix A, Table 3 outlines staged communication mechanisms, some of which may be implemented by Water Authority.

8.7 Compliance and Enforcement
In accordance with CWC Section 10632(a)(6), the City emphasizes education as the primary approach to address violations of water use restrictions during shortage conditions. When educational efforts are ineffective, enforcement measures outlined in Section 31-235 of the City’s Municipal Code will apply. These measures may include fines, installation of flow-restricting devices, and other civil or criminal penalties. The Municipal Code will be updated by City Council action to align with revised water shortage levels in Section 31-232. Current fine structures are specified in the City’s Municipal Code.

Public Review Draft 8-9

8.8 Legal Authorities
The City has broad legal authority under California law to implement and enforce water shortage contingency measures. This authority is derived from multiple provisions, including:
 California Constitution Article X, Section 2 and Water Code Section 100, which require water to be used beneficially and prohibit waste or unreasonable use.  Water Code Sections 350–377, granting authority to declare a water shortage emergency and impose conservation measures when ordinary demands cannot be met without depleting supplies.
 Additional statutes under Water Code Chapters 3.3 and 3.5, Division 6, and the California Emergency Services Act, which allow enforcement of water use restrictions during emergencies.  Upon a Governor’s proclamation of a state of emergency due to drought, local WSCP implementation takes precedence where practicable.

The City may restrict water use and prohibit waste for all non-essential purposes to protect public health, sanitation, and fire protection. It will also coordinate with local jurisdictions, including the County of San Diego and the Water Authority, when declaring a local emergency.

8.9 Financial Consequences of WSCP Implementation
Implementing the WSCP can have significant financial impacts on the City. Reduced water sales during shortage conditions result in lower revenue, while compliance and enforcement activities may increase operational costs. The City adjusted water and wastewater rates in 2023 (effective January 1, 2025) to address rising wholesale costs, fund critical capital improvement projects, and enhance system reliability.

To mitigate financial impacts, the City may rebalance water sources to reduce costs, such as drawing more from local storage once infrastructure upgrades are complete. Robust operating and capital improvement reserves are available for short-term needs, though long-term replenishment may require rate adjustments.

Additional costs may arise from monitoring and enforcing compliance during shortage stages, including staff time and outreach efforts. These costs will be tracked when a shortage is declared.

8.10 Monitoring and Reporting
The City will annually track supplies and projected demands and activate the WSCP when supply conditions warrant, using demand monitoring to confirm whether response actions are achieving the required reductions. Water savings will be evaluated using monthly production reports compared against past months, the same month in previous years, and allocated supplies, with assessments beginning at the sector level and expanding to individual accounts if necessary while accounting for weather and other influencing factors. Additionally, the City will continue submitting the State Water Board Urban Water Supplier Monthly Water Conservation Report detailing shortage stages, production data, water use categories, enforcement, compliance, and response actions— and integrate this reporting into its annual WSCP assessment process.

8.11 WSCP Refinement Procedures
The WSCP is designed to be adaptive and updated as needed to address both foreseeable and unforeseen water shortage conditions. To maintain effectiveness, the City will continually evaluate requirements, criteria, and response actions based on lessons learned during implementation and results from monitoring and reporting programs.

Potential refinements will be documented and incorporated into the next WSCP update. Changes that may warrant an update include adjustments to shortage level triggers, modifications to the stage structure, or the addition of new response actions. Newly identified actions may initially be introduced as voluntary measures until formally adopted as mandatory.

8.12 Special Water Feature Distinction
In compliance with CWC Section 10623(b), the City distinguishes between water features such as ponds, lakes, waterfalls, fountains, and swimming pools or spas. Non-pool water features may use recycled water, whereas pools and spas require potable water for health and safety reasons.

Under normal conditions, ornamental fountains and decorative water features must use recirculated water. During a Stage 4 shortage, filling or refilling ornamental lakes or ponds is prohibited, except when necessary to sustain aquatic life of significant value that was actively managed prior to the declaration of the shortage stage.

8.13 Plan Adoption, Submittal, and Availability
The City’s WSCP was prepared and will be adopted in accordance with California Water Code Section 10632(a)(3)(C). The WSCP will be presented at a duly noticed public hearing and formally adopted by the City Council on May 13, 2026. Required public and agency notifications were provided, and the WSCP was made available for public review prior to adoption.

Following adoption, the WSCP was made publicly available within 30 days and submitted electronically to the Department of Water Resources (DWR) through the Water Use Efficiency (WUE) Data Portal concurrent with the UWMP. Hard copies of the adopted WSCP and UWMP were submitted to the California State Library, and copies were distributed to applicable cities and counties within the City’s service area within 30 days of adoption. Any future amendments required by DWR will be adopted by the City Council and resubmitted to DWR within 30 days of adoption.

9 Demand Management Measures
This chapter describes the City’s efforts to promote water-use efficiency, reduce demand on water supply, and prepare for future requirements.

Chapter Overview
 Demand Management Measures

9.1 Setting
This chapter describes the water conservation programs that the City has implemented to reduce overall potable water demands and comply with California’s Making Conservation a California Way of Life framework. This framework, established by SB 606 and AB 1668, requires urban retail water suppliers to meet long‑term water use efficiency standards and annually calculate an Urban Water Use Objective (UWUO) reflecting efficient water use. The City’s water conservation programs, referred to as Demand Management Measures (DMMs) in this UWMP, support achievement of these efficiency standards and contribute to meeting the City’s UWUO over time. The required DMMs are summarized in Table 9-1. No changes to DMMs have been enacted since the 2020 UWMP.

9.2 Demand Management Measures
Consistent with the requirements of the CWC, this section describes the DMMs in Table 9-1 that have been implemented to reduce overall demand for potable water.

Water conservation, or demand management, continues to be a significant part of regional water resource planning strategies in San Diego County. The City is committed to supporting these regional water conservation activities and provides staffing and direct and indirect financial assistance. In addition, the City implements local DMMs to augment and complement regional programs.

9.3 Water-Waste Prevention Ordinances
A water waste ordinance explicitly states that the waste of water is prohibited. The ordinance may prohibit specific actions that waste water, such as excessive runoff from landscape irrigation or a hose outdoors without a shut-off nozzle. The City has ordinances to promote conservation and increase water efficiency with its customers.

In 2008, the City adopted a Water Conservation Plan under Article 5, Chapter 31 of the Escondido Municipal Code to address water waste measures. The Water Conservation Plan was updated in 2015 pursuant to Ordinance No. 2015-12R and is located in Appendix H. The City’s Water Conservation Plan includes measures with four stages that are in place during water shortage conditions. The following water uses are prohibited at all times:
 Watering or irrigating lawns or landscape areas in a manner causing significant runoff.  Operating a fountain or other water feature that does not recirculate water.  Washing any vehicle with a hose not having a water shut-off nozzle.  Allowing water to run continuously from a hose while washing any vehicle.  Washing driveways, sidewalks, parking areas, patios, or other hardscape areas with water, except when necessary to alleviate safety or sanitation hazards.  Using water (unnecessarily) for construction operations, receiving water from a construction meter or water truck for any purpose other than those required by regulatory agencies.  Watering or irrigating outdoor landscaping with potable water during a measurable rainfall event or within 48 hours of measurable rainfall.
 The installation of single pass cooling systems in buildings requesting new water connections.  The installation of non-recirculating systems in new or remodeled conveyor or automatic car wash systems.

The following water use restrictions are required at all times:
 The loss or escape of water by means of breaks, leaks, or other malfunctions in the water user’s plumbing or distribution system must be repaired within five days of notification by the utilities department, or within such other time as determined by the director of utilities or designee.  Golf courses, parks, school grounds, landscapes, and recreational fields must only be watered between the hours of 6:00 p.m. and 10:00 a.m., except for very short periods of time for the express purpose of adjusting or repairing the irrigation system. Tees and greens may be watered at any time. New plantings including grass may be watered as needed until established.  Recycled water must be used, after the department has provided to the customer an analysis showing that recycled water, if available, is a cost-effective alternative to potable water and the customer has had a reasonable amount of time, as determined by the director or the director's designee, to make the conversion to recycled water.
 A hotel or motel must provide guests the option of refusing daily laundering of towels and linens. The hotel or motel shall prominently display notice of this option in each bathroom and sleeping room using clear and easily understood language. The department shall make suitable displays available.

Demand Management Measures

Urban Water Management Plan 9-3
 Restaurants or other public places where food is served, sold, or offered for sale, will not serve drinking water to any customer unless expressly requested by the customer. The department shall make "table tents" available to restaurants and these types of other public places alerting customers to this restriction.
 All conveyor or automatic car wash systems shall have installed operational water recycling systems, or shall have secured a waiver of this requirement from the director.  All laundromats shall have converted 100% of their washers to high-efficiency models, as determined by the Consortium for Energy Efficiency, by November 22, 2015.  Irrigating landscapes with potable water for new construction must be consistent with regulations established by the California Building Standards Commission and the Department of Housing and Community Development.

9.4 Metering
The City is fully metered and uses metering data to apply water rates based on water consumption.

Additionally, when water allocations are in effect, the City could use metering data to determine whether customers are in compliance with mandatory water-use restrictions. The City has the ability to impose an additional surcharge to any customer showing excess water usage above the allocation amount.

Meters are replaced on a 15-year schedule. Testing is done on a percentage of the small meters as they are pulled from service. Large meters (3” and larger) are tested every one, two, or three years to ensure accuracy and maintain operational integrity.

9.5 Conservation Pricing
The City adopted water budget-based tiered rate structures to manage water supply and promote conservation as reflected in Table 9-2. Residential customers are billed under an inclining block rate structure, which charges progressively higher rates as consumption increases. This structure was reaffirmed and updated through the City’s 2023 Comprehensive Water Rate Study and implemented under Resolution No. 2023-131, replacing earlier versions from 2015 and 2021.

The updated rate design aligns with conservation objectives by incentivizing efficient water use and discouraging excessive consumption. When water allocations are in effect, customers exceeding their assigned allocation may incur additional surcharges.

Current potable water rates include three tiers for single-family residential customers, two tiers for multi-family accounts, and uniform rates for commercial, irrigation, and agricultural customers.

These tiers are structured to reflect cost-of-service principles while supporting statewide conservation mandates.

The City also maintains a fixed readiness-to-serve charge based on meter size, ensuring system reliability and funding infrastructure needs. Rates are subject to automatic pass-through adjustments for wholesale water costs and inflation, as authorized under Proposition 218 and California Government Code §53756.

This conservation-oriented pricing strategy is a key component of the City’s UWMP and WSCP. The 2023 Comprehensive Water Rate Study provides the City’s block rate structure for potable water per an updated rate structure that went into effect on January 1, 2024.

9.6 Public Education and Outreach
The City continues to deliver a dynamic outreach and education program, using a blend of traditional communication, experiential learning, and digital platforms. This includes bill inserts, flyers, enhanced web resources, webinars, workshops, classroom presentations, and conservation tools.

Since 2020, in direct support of DMMs, the City expanded efforts to include landscape and irrigation workshops, both in-person and virtual, co-hosted with regional partners like MWD, Water Authority, and Green Gardens Group. The City also offers residential and commercial water-use evaluations, rebate programs, and informational calculators.

Youth education programs include K–5 classroom presentations, 4th-grade poster contests, and alignment with Next Generation Science Standards. COVID-era created online resources, such as on- demand videos and virtual classes, have become permanent fixtures.

These efforts are supported by City partnerships with school districts, nonprofits, and regional entities, ensuring broad community reach and reinforcing conservation behavior within the City’s customer base, which can be accessed publicly at https://www.escondido.gov/492/Environmental- Programs.

9.7 Programs to Assess and Manage Distribution
System Real Loss
The City continues to conduct monthly water meter readings, using advanced meter data analytics to identify potential leaks or abnormal usage patterns. Customers are notified when anomalies are detected, and the City offers customer service appointments to assist with leak detection and repairs.

The City’s Water Conservation webpage (https://www.escondido.gov/747/Water-Conservation) remains a key resource, providing instructions on how to read a water meter and monitor usage. In addition, the City has expanded its digital tools, including online leak detection guides, interactive water-use calculators, and video tutorials to help customers self-monitor and reduce waste.

Since 2020, the City has implemented the following initiatives:
 Annual AWWA Water Audits: The City now performs yearly audits following AWWA M36 guidelines, improving accuracy in tracking real and apparent losses.  AMI (Advanced Metering Infrastructure) Pilot Program: Deployment of smart meters in select service areas enables near real-time monitoring, reducing response time for leaks and breaks.  Pressure Management Program: Targeted pressure zone adjustments have reduced stress on aging infrastructure, lowering the frequency of main breaks.  District Metered Areas (DMA) Analysis: The City has begun segmenting its distribution system into DMAs to better isolate and quantify losses.
 Active Leak Detection Surveys: Contracted acoustic leak detection surveys are conducted annually, identifying hidden leaks before they escalate.  Customer Engagement: Expanded notification includes email alerts and portal notifications when unusual consumption is detected.

These efforts have resulted in measurable improvements in system efficiency and reduced real losses compared to previous audit benchmarks.

9.9.5 Turf Replacement Program
In 2023, California adopted new statewide requirements that affect turf. AB 1572 prohibits the use of potable water to irrigate nonfunctional (ornamental) turf at non-residential properties, with phased compliance beginning in 2027 for government facilities, 2028 for CII properties, and 2029 for HOA common areas. Functional turf and areas irrigated with recycled or harvested water are exempt. Additionally, SB 676 allows local jurisdictions to regulate or restrict artificial turf installations by clarifying that synthetic turf does not qualify as drought-tolerant landscaping.

The City has participated in various turf replacement programs to support long-term potable water savings and reinforce the need for ongoing turf replacement and landscape transformation programs. Approximately 22 residential sites and one CII site within the City participated in the Water Authority’s program to replace water-intensive turf with water-efficient landscaping. Under this program, a total of 1,352,272 square feet of turf was converted in the City. Approximately 534 applicants within the City participated in MWD’s program, replacing approximately 927,631 square feet of turf. The City will continue to participate as programs are available and is working towards addressing new statewide requirements to implement AB 1572.

Introduction

Public Review Draft 1
1 Introduction
This Water Shortage Contingency Plan (WSCP) describes how the City of Escondido (City) intends to predict and respond to foreseeable and unforeseeable water shortages, which occur when available water supplies are reduced to a level that cannot support typical demand at any given time. The WSCP serves as a planning document to guide the City Council, staff, and the public by identifying response actions that allow for efficient and accountable management of water shortages with predictability and transparency. While the WSCP does not provide absolute direction, it offers a range of response options to address varying water shortage conditions.

Water shortages may be triggered by hydrologic limitations in supply—such as prolonged periods of below-normal precipitation and runoff—failures or limitations in supply or treatment infrastructure, or a combination of both. Hydrologic or drought-related shortages typically develop and subside gradually, whereas infrastructure-related shortages tend to occur more suddenly and unpredictably.

Water supplies may be interrupted or substantially reduced due to events such as drought, earthquakes that damage delivery or storage facilities, regional power outages, or toxic spills that affect water quality.

This WSCP describes the following:

1. Water Supply Reliability Analysis. Summarizes the City’s water supply analysis and reliability and identifies the key issues that may trigger a shortage condition.

2. Annual Water Supply and Demand Assessment Procedures. Describes the key data inputs, evaluation criteria, and methodology for assessing the system’s reliability for the coming year and the steps to formally declare any water shortage levels and response actions.

3. Six Standard Shortage Stages. Establishes water shortage levels to clearly identify and prepare for shortages.

4. Shortage Response Actions. Describes the response actions that may be implemented or considered for each stage to reduce gaps between supply and demand as well as minimize social and economic impacts to the community.

5. Communication Protocols. Describes communication protocols under each stage to ensure customers, the public, and City Council are informed of shortage conditions and requirements.

6. Compliance and Enforcement. Defines compliance and enforcement actions available to administer demand reductions.

7. Legal Authority. Lists the legal documents that grant the City the authority to declare a water shortage and implement and enforce response actions.

8. Financial Consequences of WSCP Implementation. Describes the anticipated financial impact of implementing water shortage stages and identifies mitigation strategies to offset financial burdens.

9. Monitoring and Reporting. Summarizes the monitoring and reporting techniques to evaluate the effectiveness of shortage response actions and overall WSCP implementation. Results are used to determine if additional shortage response actions should be activated or if efforts are successful and response actions should be reduced.

10. WSCP Refinement Procedures. Describes the factors that may trigger updates to the WSCP and outlines how to complete an update.

This WSCP was prepared in conjunction with the City’s 2025 Urban Water Management Plan (UWMP) (City of Escondido, 2025). This document is compliant with the California Water Code (CWC) Section 10632 and incorporated guidance from the California Department of Water Resources (DWR) 2025 UWMP Guidebook, and the American Water Works Association (AWWA) Manual of Water Supply Practices (M60) Drought Preparedness and Response. In addition, the San Diego County Water Authority (Water Authority) 2025 WSCP (Water Authority, 2026b) was used to align with regional efforts.

Water Supply Reliability Analysis

Public Review Draft 3
2 Water Supply Reliability Analysis

2.1 Supply Characterization
The City receives the majority of its water from the Water Authority in the form of raw water that the City treats at its water treatment plant along with local surface water. The Water Authority’s core water sources used to supply the City are imported water from the Water Authority-Imperial Irrigation District (IID) Water Conservation and Transfer Agreement and the All-American Canal and Coachella Canal Lining Projects, along with purchased water from the Metropolitan Water District of Southern California (MWD). The City does not receive any treated water from the Water Authority, which also means it does not receive any water from the Claude “Bud” Lewis Carlsbad Desalination Plant even though desalinated seawater is a portion of the Water Authority’s supply portfolio. In 2018, the City started receiving water from the San Luis Rey Indian Water Authority (SLRIWA) Settlement Agreement through the Water Authority.

2.1.1 San Diego County Water Authority – Imperial Irrigation District Water Conservation and Transfer Agreement
In 1998, the Water Authority entered into a Water Conservation and Transfer Agreement with IID, an agricultural district in the neighboring Imperial County. Through this transfer agreement, the Water Authority began receiving conserved water from IID after the execution of the 2003 Quantification Settlement Agreement with an initial transfer of 10,000 AF. Per the terms of the agreement, the volume delivered increased year-over-year until it reached 200,000 AFY in 2021 and will then remain fixed for the remainder of the duration of the Transfer Agreement. The Transfer Agreement's initial term is 45 years, with a provision that either agency may extend the agreement for an additional 30-year term.

2.1.2 All-American Canal and Coachella Canal lining Projects In 2003, as part of the execution of the Quantification Settlement Agreement on the Colorado River, the Water Authority contracted for 77,700 AFY of conserved water from projects to line portions of the All American Canal and Coachella Canal. The lining projects reduced the loss of water that occurred through seepage. Deliveries of conserved water from the Coachella Canal reached the region in 2007, and deliveries from the All-American Canal reached the region in 2010. This conserved water will provide an additional 8.5 million AF over the 110-year life of the agreement.

Supplies from the canal lining projects are considered verifiable Water Authority supplies.

2.1.3 Metropolitan Water District of Southern California The Water Authority relies on water purchased from MWD to meet its supplemental supply gap.

Historically, the Water Authority relied solely on imported water from Metropolitan to meet the needs of its member agencies. However, after experiencing severe shortages from MWD during the 1987 to 1992 drought, the Water Authority began pursuing actions to diversify the region’s supply sources. Currently, MWD’s supplies come from two primary sources: the State Water Project and the Colorado River. The Water Authority receives a variable blend of the two sources depending on State Water Project allocations which change annually depending on statewide hydrology, existing reservoir storage, and regulatory requirements in the Sacramento-San Joaquin Delta.

4 2.1.4 San Luis Rey River Water Transfer
In 2018, the City and Vista Irrigation District (VID) began receiving water deliveries from the SLRIWA as part of the San Luis Rey Indian Water Rights Settlement Act. The San Luis Rey Indian Water Rights Settlement Act was passed by Congress in 1988 to settle disputes between the Settlement Parties.

The Settlement Parties are listed as follows:
 Indian Bands — The Indian Bands are comprised of the La Jolla, Rincon, San Pasqual, Pauma, and Pala Bands of Mission Indians. Each band acts through a governing body that is recognized by the U.S. Secretary of the Interior
 Local Entities — The Local Entities are the VID and the City of Escondido  San Luis Rey Indian Water Authority (SLRIWA)
This act created the San Luis Rey Water Transfer supply, which authorized up to 16,000 AF per calendar year of conserved water from projects like the All-American Canal and the Coachella Canal Lining Projects for the Settlement Parties to resolve water right disputes on the San Luis Rey River.

The Indian Bands have the initial right to use or exchange this Supplemental Water, with any unused portioned delivered to the City and VID, generally in qual shares. The Water Authority is required to convey the supplemental water transfer supplied by the SLRIWA to the Local Entities.

Additionally, the Agreement for the Conveyance of Water Among the San Diego County Water Authority, the San Luis Rey Settlement Parties, and the United States, was entered into on October 10, 2003. This agreement established terms and conditions for the Supplemental Water Transfer deliveries that included obligation conditions, transportation rate, and creation of a delivery protocol document.

On December 5, 2014, the San Luis Rey Indian Water Rights Implementing Agreement was entered into by the City, VID, the State of California, the SLRIWA, and the Bands for the purpose of resolving all claims, controversies, and issues involved in all of the pending proceedings among the parties.

Local Surface Water
The City’s utilizes local surface water from Lake Henshaw, Lake Wohlford, and Lake Dixon reservoirs.

These reservoirs are shared with VID. Local water originates from the San Luis Rey River watershed and Lake Henshaw. Water from Lake Henshaw is transferred to Lake Wohlford via the San Luis Rey River and the Escondido Canal, originally constructed in the 1890s. Water from Lake Wohlford is delivered to the City via the Escondido Canal, the Bear Valley Hydroelectric plant, and associated pipelines. Additional raw water is purchased from Water Authority and stored in Lake Dixon. Local surface water supply availability is variable depending on the hydrologic patterns and can provide up to 30% in wet years. Local surface water is treated at the Escondido-Vista Water Treatment Plant.

2.2 Reliability Assessment
Chapter 7 of City’s 2025 UWMP describes the reliability of the City’s water supply by comparing supply and demand projections through 2045 for normal, single-dry, and five consecutive dry years.

The chapter also assesses the drought risk over the next five years (2021 to 2025) assuming the driest five-year period is repeated over the next five years. Water supply reliability reflects the City’s ability to meet the water needs of its customers with water supplies under varying conditions. The Resolution No. 2026-67
Exhibit "A"

353
Item14.

Water Supply Reliability Analysis

Public Review Draft 5
analysis considers plausible hydrological and regulatory variability, climate conditions, and other factors that affect the City’s water supply and demand. The 2025 reliability analysis indicates that the City’s water supplies are reliable, and no shortages are anticipated, even with conservative assumptions about the availability of dry year supplies from Metropolitan and the Water Authority.

As a member agency of the Water Authority, the City benefits from significant regional efforts to plan and develop a diverse and resilient water portfolio.

2.3 2026-2030 Drought Risk Assessment
CWC Section 10635 (b) requires a drought risk assessment (DRA) to be included in the UWMP. The DRA provides an overview of the anticipated surplus or deficit if a drought were to occur in the next five years. The DRA evaluates each water supply’s reliability and compares available water supplies and projected demands during a five-consecutive dry-year scenario. This short-term analysis can help water suppliers foresee undesired risks, such as upcoming shortages, and provide time to evaluate and implement the necessary response actions needed to mitigate shortages in a less impactful manner to the community and environment.

The City maintains flexibility that helps to offset water shortage impacts. The DRA for the upcoming five years (2026-2030) is based on the five driest years on record (2014-2018) and is consistent with the approach used by the Water Authority. The 2014-2018 period had the lowest local water supply production from surface water and groundwater, the two Water Authority local supply sources that are most susceptible to weather variation. As experienced in the past, the City’s local water supply sources vary greatly in dry years. As a result, the City may rely on the Water Authority to meet demands when local supply sources are reduced. The Water Authority does not anticipate any reduction in supply availability over the next five years.

The DRA compared anticipated available supplies with projected water demands. The City expects to use only what is needed to meet demands using a blend of local and imported water sources.

Demands for the DRA were determined by applying a demand multiplier to 2025 demand. Demand multipliers were developed by the Water Authority and used in their UWMP analysis. Details on demands for the DRA are discussed in Chapter 7 of the City’s UWMP.

Because of the flexibility of supply and reliability of the Water Authority, the City expects to meet demands over the next five years without the need to implement this WSCP. The Water Authority’s DRA concluded that actions under the WSCP are not required. Similarly, because of the Water Authority’s analysis and large amounts of surplus, the City does not expect any water supply shortages or the need to implement their WSCP. Despite this large amount of surplus supply, the City will continue to promote conservation and avoid water waste.

2.4 Water Supply Reliability Risks
The City’s water supply may be threatened by different risks which are summarized below and detailed in Chapter 7 of the 2025 UWMP.

Imported water and surface water supplies may be significantly affected by climate change. Climate change is anticipated to increase the frequency and intensity of droughts and flooding, alter the timing of snowmelt, and increase variability in precipitation while raising average temperatures and increasing sea levels. This may affect the amount of water available in the Sacramento-San Joaquin Resolution No. 2026-67

6 Delta and Colorado River systems, the San Luis Rey River, and Lake Henshaw, possibly limiting the City’s access to imported and surface water supplies.

Although the Water Authority water supplies are reliable, failure of the Water Authority aqueduct system that conveys water to the region could be catastrophic. To increase water reliability and redundancy throughout the County, the Water Authority initiated the Emergency Storage Project (ESP). The ESP is comprised of various projects, including the construction of new reservoirs, pump stations, and aqueduct upgrades to increase local storage and diversify the conveyance of water.

Annual Water Supply and Demand Assessment

Public Review Draft 7
3 Annual Water Supply and Demand
Assessment
As established by CWC Section 10632.1, urban water suppliers must conduct an annual water supply and demand assessment (Annual Assessment) and submit an annual water shortage assessment report to DWR. The Annual Assessment is an evaluation of the short-term outlook for supplies and demands to determine whether the potential for a supply shortage exists and whether there is a need to trigger a WSCP shortage level and response action in the current fiscal year to maintain supply reliability. Beginning in 2022, the City must prepare their annual water supply and demand assessment and submit an Annual Water Shortage Assessment Report to DWR. An extension may be allowed since the City receives the majority of its water from the State Water Project through the Water Authority.

Due to reliance on the Water Authority’s available supply, the annual report's preparation will be subject to the Water Authority’s annual assessment process, which is discussed in Chapter 11 of their 2025 WSCP (Water Authority, 2026a). The Water Authority’s Annual Assessment focuses on the demand and supplies available to municipal and industrial (M&I) customers and covers the current year and one dry year. The Water Authority Annual Assessment is conducted in steps to determine if a regional customer demand reduction is needed and, if so, identify the appropriate shortage response level and actions.

The Water Authority’s Annual Assessment steps identified in their 2025 UWMP Chapter 11.3.2 are presented below:

1. Water Authority core water supplies are considered as part of the annual assessment including water supplies from the Lewis Carlsbad Desalination Plant, Quantification Settlement Agreement, and Metropolitan. Evaluation of core water supplies includes an assessment of the infrastructure’s capabilities and constraints that affect delivery.

2. Water Authority member agency projected water demands on the Water Authority are considered. Demand for water in the Water Authority's service area falls into two classes of service: M&I and Permanent Special Agricultural Water Rate demand. The annual assessment considers only M&I water use, which encompasses a wide range of water uses, including residential demand (water used for human consumption in the home, domestic purposes, and outdoor residential landscaping) and water used for commercial, industrial, and institutional (CII) purposes. To project M&I water demands, the Water Authority uses a short-term forecast model that considers multiple variables, including historic water demand patterns, weather, local economic index, and anticipated conservation levels. Demand on the Water Authority is also influenced by member agency local supply levels which may be influenced by weather and other factors.
a. If a water supply shortfall is identified or exists, the Water Authority evaluates the use of stored water reserves from carryover storage reserves or to pursue additional supply augmentation measures, such as dry-year transfers, to reduce or eliminate the shortfall. b. If a water supply shortfall does not exist, consistent with the Carryover Storage Policy Guidelines, the Water Authority will analyze how to most effectively manage storage supplies to avoid potential shortages in the future.

City of Escondido
2025 Water Shortage Contingency Plan

8 After this evaluation, the Water Authority will inform the City if a shortage condition exists, and the corresponding percent reduction needed, and/or the water allocations established. The City’s shortage response will be based on supply conditions reported from the Water Authority while also reporting and taking into consideration the City’s demand quantities and local supplies.

For the purpose of the WSCP, agricultural users not participating in the Permanent Special Agricultural Water Rate are treated the same as M&I users and are subject to the same water rates.

Under the Permanent Special Agricultural Water Rate Program, agricultural users are exempt from paying the Water Authority‘s storage charge and, in return, will not receive supplies from the Carryover Storage Project during shortages and limited supplies from the ESP (Water Authority, 2026a).

3.1 Key Data Inputs and Evaluation Criteria
Key data inputs and their sources for the City’s Annual Assessments are below. Evaluation criteria that can be used to determine and declare the severity of supply shortages may include any, or combinations, of the following:
 Current year unconstrained demand.
 Current year available supply from the Water Authority in the current year and one dry year.  Existing infrastructure capabilities and plausible constraints – reflects limited production and distribution capacity due to a variety of factors potentially including, but not limited to, man- made or natural catastrophic events.
 State mandates or mandatory compliance with water use efficiency standards.  Other locally applicable evaluation criteria as necessary.

3.2 Annual Assessment Procedures
The City will perform the Annual Assessment between March and June, in relation to the Water Authority’s Annual Assessment. The report is due to DWR July 1st of every year.

Steps to conduct the Annual Assessment are as follows:

1. Compile and analyze historical water customer demand for trends and/or abnormalities.

2. Determine annual demand.

3. Confirm that customer demand is met through available water supply from the Water Authority and local supply or identify shortage stage if needed.

4. Staff analyzes demand trends, water supply conditions, and available supply from the Water Authority.

5. Staff develops Annual Assessment Report.

6. Findings and recommendations are presented to the City Council. Based on the results of the Annual Assessment, the City Council may formally adopt and declare a water shortage stage.

7. Submit Annual Assessment to DWR.

Six Standard Water Shortage Levels

Public Review Draft 9
4 Six Standard Water Shortage Levels
Per CWC Section 10632(a)(2), the City has established six standard water shortage levels. Shortage levels indicate the gap in supply compared to normal year availability. The six shortage stages correspond to 10%, 20%, 30%, 40%, 50%, and greater than 50% shortage compared to normal supply conditions. DWR standardized the shortage levels to provide a consistent regional and statewide approach to measure water supply shortage conditions. However, a water supplier may maintain its current shortage levels if a crosswalk relating its existing shortage levels to the six standard levels is included.

The City updated its shortage stages to the six standard stages to align with the Water Authority’s shortage stages. In general, the Water Authority will notify the City if there is a reasonable probability there will be a supply shortage and that consumer demand reduction is required to ensure that sufficient supplies will be available to meet anticipated demands. The City will independently review and adopt any retail-level actions determined necessary to manage potential water supply shortage.

Table 1 shows the Regional Water Shortage Stages as prepared by the Water Authority. The restrictions become more stringent at each successive level to obtain the necessary savings and delay economic impact until higher levels.

10 4.1 Shortage Response Actions
CWC Section 10632(a)(4) and 10632.5(a) describe the response actions that must be implemented or considered for each stage to minimize social and economic impacts to the community. This WSCP identifies various actions to be considered by the City Council.

In the event of a water shortage, the City will evaluate the cause of the shortage to help inform which response actions should be implemented. Depending on the nature of the water shortage, the City can elect to implement one or several response actions to mitigate the shortage and reduce gaps between supply and demand. It should be noted that all actions listed for Stage 1 apply to Stage 2, 3, 4, 5, and 6. Likewise, Stage 2 actions apply to Stages 3, 4, 5, and 6. Stage 3 actions apply to Stage 4, 5, and 6. Stage 4 actions apply to Stage 5 and 6. Stage 5 actions also apply to Stage 6. If necessary, the City may adopt additional actions not listed here in extreme circumstances.

Chapter 31 Article 5 of the City’s Municipal Code (Attachment 1) provides standing authorization for water use restrictions and prohibitions to become effective upon adoption of a water supply shortage stage at any regular or special meetings by the City Council.

4.1.1 Demand Reduction
The City supports the efficient use of water at all times. As such, it has a baseline of permanent water use restrictions and measures that apply during normal supply or water shortage conditions (see Section 2.4.4). The City promotes individual actions on an on-going basis through its education and outreach resources.

The City has identified a variety of demand reduction actions to offset supply shortages. Demand reduction measures are strategies intended to decrease water demand to close the gap between supply and demand. The City employs a variety of techniques to encourage community members to be more involved and educated about water conservation. These techniques include actions planned to be taken at the consumer level including, but not limited to, leak detection and repair, limitations on irrigation, and additional voluntary actions to reduce customer demand. A full list of demand reduction methods preformed at various supply shortage stages are provided in Table 2 and discussed below.

4.1.2 Supply Augmentation
The City does not plan to utilize additional supply sources during a water shortage, but rather mitigate supply impacts through demand reduction actions and/or utilize additional imported water to meet demands. Therefore, no supply augmentation and other actions are reported in DWR Table 8-2.

4.1.3 Operational Changes
During shortage conditions, operations may be affected by demand reduction responses.

Operational changes to address a water shortage may be implemented based on the severity of the reduction goal. The City, with City Council approval as needed, will consider their operational procedures at the time of a shortage to identify changes they can take to maximize supply and reduce demand during a water shortage stage.

These potential actions, depending on shortage levels, could include, but are not limited to:
 Expansion of public information campaign to educate and inform customers of the water shortage emergency and required water savings
 Provide information regarding rebates for plumbing fixtures and landscape irrigation  Offer water use surveys
 Monitor construction meters for efficient water use
 Decrease line flushing to only on a compliant basis
 Implement or modify drought rate structure or surcharge or water emergency tiered pricing, pursuant to the requirements of Proposition 218 and in accordance with California Law  To manage any impact from lower retail water sales, review opportunities to reducing overhead in the short-term and mid-term by deferring non-critical Capital Improvement Program and major maintenance expenditures, and in the long-term by adjusting operational and staffing levels
 To manage any impact from lower retail water sales, review non-critical facility replacement projects for any opportunities to extend the master planned replacement schedule

4.1.4 Additional Mandatory Restrictions
In addition to any shortage response level being declared, the City maintains the following prohibitions and restrictions at all times. Per the City’s Ordinance No. 2015-12R, the following water uses are prohibited:
 Watering or irrigating lawns or landscape areas in a manner causing significant runoff.  Operating a fountain or other water feature that does not recirculate water.  Washing any vehicle with a hose not having a water shut-off nozzle.  Allowing water to run continuously from a hose while washing any vehicle.  Washing driveways, sidewalks, parking areas, patios, or other hardscape areas with water, except when necessary to alleviate safety or sanitation hazards.  Using water (unnecessarily) for construction operations, receiving water from a construction meter or water truck for any purpose other than those required by regulatory agencies.  Watering or irrigating outdoor landscaping with potable water during a measurable rainfall event or within 48 hours of measurable rainfall.

 The installation of non-recirculating systems in new commercial laundry systems The following water use restrictions are required at all times:
 The loss or escape of water by means of breaks, leaks, or other malfunctions in the water user’s plumbing or distribution system must be repaired within five days of notification by the utilities department, or within such other time as determined by the director of utilities or designee.  Golf courses, parks, school grounds, landscapes, and recreational fields must only be watered between the hours of 6:00 p.m. and 10:00 a.m., except for very short periods of time for the express purpose of adjusting or repairing the irrigation system. Tees and greens may be watered at any time. New plantings including grass may be watered as needed until established.  Recycled water must be used, after the department has provided to the customer an analysis showing that recycled water, if available, is a cost-effective alternative to potable water and the customer has had a reasonable amount of time, as determined by the director or the director's designee, to make the conversion to recycled water.
 A hotel or motel must provide guests the option of refusing daily laundering of towels and linens. The hotel or motel shall prominently display notice of this option in each bathroom and sleeping room using clear and easily understood language. The department shall make suitable displays available.
 Restaurants or other public places where food is served, sold, or offered for sale, will not serve drinking water to any customer unless expressly requested by the customer. The department shall make "table tents" available to restaurants and these types of other public places alerting customers to this restriction.
 All conveyor or automatic car wash systems shall have installed operational water recycling systems or shall have secured a waiver of this requirement from the director.  All laundromats shall have converted 100% of their washers to high efficiency models, as determined by the Consortium for Energy Efficiency, by November 22, 2015.  Irrigating landscapes with potable water for new construction must be consistent with regulations established by the California Building Standards Commission and the Department of Housing and Community Development.

4.1.5 Emergency Response Plan
The Director may declare a catastrophic water supply shortage in accordance with the City’s emergency response plan and at the direction of the City Manager. When a catastrophic water supply shortage is in effect, the Director may impose any emergency water allocation or conservation actions that are deemed necessary to protect the reliability and quality of the City’s water supply and with the approval of City Council, as required. Details on the authority and provisions associated with a sudden catastrophic water supply shortage are detailed in Section 31- 233 of the City’s Municipal Code.

In addition to responding to drought conditions, the City’s WSCP can be used to respond to emergency or catastrophic conditions that impact the availability of the City’s water supplies and/or the ability to deliver water within the service area. Besides drought, water supply may experience a Resolution No. 2026-67

Public Review Draft 15
catastrophic interruption as a result of natural disasters such as an earthquake, tsunami, wildfire, mudslide, or a regional power outage.

Planning and response measures in the event of an interruption to the water supply include:
 In advance of a known threat to the water and distribution system, such as a wildfire, distribution reservoirs will be filled to full capacity and any reservoir out of service will be put back into service.
 Portable generators will be deployed to critical facilities lacking emergency back-up power.  Supervisory Control and Data Acquisition is used throughout the distribution system to monitor system problems, whether minor day to day problems or major disruptions.  City distribution system crews are trained in pipe repair and replacement as a part of their normal duties and are continually ready to perform such work on an emergency basis as needed.
 In the occurrence of a catastrophic event, City employees are prepared to mobilize to respond to emergent issues.
 Prioritize distribution system repairs to best meet critical needs, including water for firefighting and health and safety needs; identify a portion of available potable supply to be reserved for drinking water purposes in the event of prolonged interruption.  Develop a clear message for timely information dissemination to the public that includes nature of the catastrophic event, status of distribution system, water use prohibitions, allowable water uses, potential need to boil drinking water prior to consumption, and location and availability of emergency drinking water, in the event of distribution system failure.

In 2020, the City completed a Risk and Resilience Assessment (RRA) and Emergency Response Plan (ERP) in accordance with America’s Water Infrastructure Act (AWIA) of 2018. Consistent with AWIA requirements, the RRA was reviewed and updated in March 2025. The purpose of the RRA and ERP is to meet the AWIA compliance requirements and plan for long-term resilience of the City’s infrastructure. The RRA assessed the City’s water system to identify critical assets and processes that may be vulnerable to human and natural hazards, and to identify measures that can be taken to reduce risk and enhance resilience from service disruption for the benefit of customers. The RRA identified and characterized both infrastructure-specific and system-wide vulnerabilities and threats and quantified the consequences of disruption. The RRA also identified various options (and constraints) in addressing and mitigating risk. The RRA, in conjunction with the ERP, charted a course for water system resilience. The RRA also provided various recommendations to increase reliability of the City’s system. Since critical pieces of infrastructure and specific vulnerabilities are detailed in the RRA and ERP, the contents of the document are confidential and for use by City’s staff only. However, the City can confirm that these plans meet the requirements set forth by AWIA and evaluate seismic risks and mitigation actions to the City’s infrastructure.

4.1.6 Seismic Risk Assessment and Mitigation Plan
The City certified with the U.S. Environmental Protection Agency that their RRA and ERP were compliant with all AWIA requirements on March 31, 2020 and December 30, 2020, respectfully, meeting all federal deadlines. In addition, the San Diego County’s 2023 Multi-Jurisdictional Hazard Mitigation Plan also addresses risk assessment and mitigation for multiple emergency types that could create a water supply interruption and can be found at www.sandiegocounty.gov/oes/emergency_management/oes_jl_mitplan.html.

16 4.1.7 Shortage Response Action Effectiveness
As a standard operating procedure, water is tracked through the production, distribution, and billing systems. During water shortage conditions, water use can be measured in comparison to what is considered to be a normal year demand (i.e., current customer base with approximately average rainfall), or in reference to a specific base year as may be dictated by Statewide requirements.

The effectiveness of actions initiated at each shortage response is challenging to measure and can vary significantly. Estimates of the effectiveness for actions has been included in Table 2.

Effectiveness is also impacted by successful communication and outreach efforts. It is also difficult to assess the effectiveness of each activity separately as each stage implements several activities at once. For the purpose of the WSCP implementation, it is assumed that the upper end of the water savings would come from the use of multiple demand reduction actions in a stage. Reduction in the shortage gap for Stages 2-6 assume all measures in the previous stage(s) are implemented and those savings are counted toward the total reduction in the shortage gap. For example, in WSCP Stage 4, the City may limit irrigation to specific days, and this measure, along with all demand management measures in Stage 1, 2, and 3, is estimated to reduce the shortage gap by up to 40%.

Communication Protocols

Public Review Draft 17
5 Communication Protocols
CWC Section 10632(a)(5) describes the communication protocols and procedures to inform customers, the public, and state and local officials of any current or predicted water shortages. This WSCP includes a staged plan to communicate the declaration of a shortage stage, inform restrictions, and provide updates during a water shortage emergency. For general messages on regional conditions, the City will rely on the Water Authority to conduct communications and outreach about water supplies and water use efficiency as an ongoing activity during normal supply conditions. In times when the WSCP is enacted, Water Authority will convey crucial information as outlined in Section 9 of the Water Authority WSCP (Water Authority, 2026a). The City, as a member agency of Water Authority, is involved in the crafting of those messages.

The City will also share its own messages to its customers as needed for Escondido-specific information or reinforcing general guidance.

5.1 Coordination
During droughts or other times of limited supply that activate the WSCP, the Water Authority will establish more frequent schedules of updates, reports, or discussions at all levels to ensure Water Authority outreach messages and tactics stay in sync with the changing needs of member agencies and their customers. The City will strive for this same coordination between neighboring water districts to minimize the confusion for water users. The schedule and timing of these updates may adjust periodically to reflect evolving water shortage conditions or other factors.

5.2 Key Audiences
Escondido water customers inside and outside of the City boundaries, and other water users inside the City’s service area are the key audiences.

5.3 Communication Objectives
Messaging will be based on the communication objective including:
 Motivate water users to increase conservation immediately in ways that are consistent with any permanent and/or mandated actions called for at the current level of the WSCP.  Raise awareness and understanding of the drought, regulatory, or other conditions affecting water supplies and the need for increased conservation.  Lower supply shortage stage having demonstrated the effectiveness and value of conservation actions and water supply reliability investments in minimizing impacts to the region’s economy and quality of life.

18 5.4 Flexibility and Adaptability
In general, this communication plan is flexible and adaptable due to the many variables that can impact the effectiveness of this plan, including shortage level, the specific supply or regulatory circumstances driving that activation, budget availability, seasonal conditions, and other factors.

Because of these potential variations, this communication plan does not dictate every strategy and tactic or the scale of resources that need to be applied at each level of the WSCP. Rather, this plan includes recommended strategies and tactics that generally match the needs associated with the escalating levels. This is intended to give staff the flexibility to apply tailored communications approaches that best fit the specific goals at any given point and the agility to react quickly to any changes in conditions.

This WSCP includes a staged plan to outline and provide guidance for efficient communication of declaration of a shortage stage, inform restrictions, and provide updates during a water shortage emergency shown in Table 3. Note, not all the mechanisms listed will be performed by the City.

Some efforts may be completed by the Water Authority as part of their communication protocols.

Compliance and Enforcement

Public Review Draft 19
6 Compliance and Enforcement
CWC Section 10632(a)(6) describes the compliance and enforcement provisions. The City aims to educate its customers when violations occur, in an effort to avoid repeat violations and future water waste. If educational efforts are not applicable or effective for customers who do not comply with restrictions implemented in a water shortage emergency, the City will use the enforcement measures found in Section 31-235 of the City’s Municipal Code. This section of the code will be updated through City Council action to align with the changes proposed for the water shortage levels found in Section 31-232. Fines, the installation of a flow-restricting device, and other civil or criminal penalties may apply. Current fines are set forth in the City’s Municipal Code.

6.1 Legal Authorities
The City has the legal authority to implement and enforce its WSCP. California Constitution Article X, Section 2 and CWC Section 100 provides that water must be put to beneficial use, the waste or unreasonable use or unreasonable method of use of water shall be prevented, and the conservation of water is to be exercised with a view to the reasonable and beneficial use thereof in the interest of the people and the public welfare. In addition, CWC Section 375 provides the City with the statutory authority to adopt and enforce water conservation restrictions and CWC sections 350 et seq., authorize the City to declare a water shortage emergency, and impose water conservation measures when it determines that the City may not be able to satisfy ordinary demands without depleting supplies to an insufficient level.

If necessary, the City shall declare a water shortage emergency in accordance with CWC Chapter 3 (commencing with Section 350) of Division 1. Once having declared a water shortage, the City is provided with broad powers to implement and enforce regulations and restrictions for managing a water shortage.

Under California law, including CWC Chapters 3.3 and 3.5 of Division 1, Parts 2.55 and 2.6 of Division 6, Division 13, and Article X, Section 2 of the California Constitution, the City is authorized to implement the water shortage actions outlined in this WSCP. In water shortage cases, shortage response actions to be implemented will be at the discretion of the City and will be based on an assessment of the supply shortage, customer response, and need for demand reductions as outlined in this WSCP.

In addition, upon proclamation by the Governor of a state of emergency under the California Emergency Services Act (Chapter 7 (commencing with Section 8550) of Division 1 of Title 2 of the Government Code) based on drought conditions, the State will defer to implementation of locally adopted water shortage contingency plans to the extent practicable.

The City has the legal authority to declare a water shortage and implement the actions outlined in this WSCP to restrict water use and prohibit water waste for all uses that are not necessary to sustain public health, sanitation, and fire protection.

The City will coordinate with any city or county, including the following listed, 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):

Financial Consequences of WSCP Implementation

Public Review Draft 21
7 Financial Consequences of WSCP
Implementation
CWC Section 10632(a)(6) describes the financial consequences of implementing the WSCP and potential mitigation strategies. The City’s water rates were recently modified in 2023 (effective January 1, 2025) that included increases for water and wastewater due to increases in wholesale cost, development of critical capital improvement projects, and repair and replacement of at-risk facilities that are designed to increase service reliability and help the City reduce its risk of water shortages in the future.

7.1 Financial Impacts and Mitigation Action
In general, water shortages of the types discussed above necessitate selling less water. Reduced water sales would result in lower revenue. The various sources of water that are within the City’s supply portfolio come with different costs for purchasing, transporting, and treating. In the event of a water shortage, the amount of water pulled from each source could possibly be rebalanced to lower costs. This could include drawing more water from the City’s increased local storage at Lake Wohlford once the scheduled dam replacement project has been completed. The City’s Utilities Department maintains robust reserves that include consideration of emergency needs.

7.1.1 Reporting Cost of Compliance with Excessive Water Use Prohibition During Drought Emergency
To ensure City customers comply with the restrictions implemented in a water shortage emergency, additional costs may be incurred to monitor and enforce response actions. The incurred cost may vary depending on the shortage stage and duration of the water shortage emergency. The cost of compliance may be tracked when a shortage is declared. The City may track staff time and resources used to implement the WSCP, including reduced revenue, implementing and enforcing shortage response actions, and communication and outreach efforts.

The City currently has operating and Capital Improvement Program reserves, funded and available for use as intended. In the short term, the use of these reserves would have no impact on City customers or the City. In the long term, rates would possibly be raised to replenish reserves.

22 8 Monitoring and Reporting
CWC Section 10632(a)(9) describes the reporting requirements and monitoring procedures to implement the WSCP and track and evaluate the response actions effectives. As described in Section

2.2, the City intends to track its supplies and project demands on an annual basis and if supply conditions described in Table 1 are projected, the City will enact their WSCP. Monitoring demands is essential to ensure the WSCP response actions are adequately meeting reductions and decreasing the supply/demand gap. This will help to analyze the effectiveness of the WSCP or identify the need to activate additional response actions.

The water savings from implementation of the WSCP will be determined based on monthly production reports which will be compared to the supply from prior months, the same period of the prior year, and/or the allocation. At first, the cumulative consumption for the various sectors (e.g., residential, commercial, etc.) will be evaluated for reaching the target demand reduction level.

Then, if needed, individual accounts will be monitored. Weather and other possible influences may be accounted for in the evaluation.

The City is also required to submit the Urban Water Supplier Monthly Water Conservation Report, pursuant to the State Water Board Resolution No. 2020-009, which became effective on October 1, 2020. In general, the City reports the WSCP shortage stage, the total potable water production, the 2013 same month production, demand for several water uses, enforcement actions, compliance issues, and response actions. The City will continue to report this information and will integrate this process in their WSCP annual assessment process.

WSCP Refinement Procedures

Public Review Draft 23
9 WSCP Refinement Procedures
Per CWC Section 10632 (a)(10), the WSCP is intended to be adapted as needed to respond to foreseeable and unforeseeable water shortages.

To maintain a useful and efficient standard of practice in water shortage conditions, the requirements, criteria, and response actions need to be continually evaluated and improved upon 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. Results from the monitoring and reporting program will be part of the evaluation.

Potential refinements will be documented and integrated in the next WSCP update. Potential changes that would warrant an update could include, but are not limited to, any changes to shortage level triggers, changes to the shortage stage structure, and/or changes to the response actions. If new response actions are identified by staff or public, these could be advertised as voluntary actions until these are formally adopted as mandatory.

24 10 Special Water Feature Distinction
CWC Section 10623 (b) requires that suppliers analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fountains, separately from swimming pools and spas. Under City’s Ordinance No. 2015-12R, re-circulated water must be used to operate ornamental fountains or other decorative water features. At a Stage 4 condition, filling or re-filling of ornamental lakes or ponds is prohibited, except to the extent needed to sustain aquatic life, provided that such animals are of significant value and have been actively managed within the water feature prior to declaration of a Stage 4 condition.

Sec. 31-231. Reserved.

Editor’s note: Section 31-231, Additional water use restrictions, derived from Ord. Nos. 2008-30(R), 2009-16 and 2009-28, was repealed by Ord. No. 2015-12R, § 2, 6-10-15.

Sec. 31-232. Water shortage response levels.
(a) Response level one—Water shortage watch condition. (1) It is the intent of response level one to achieve up to a ten (10) percent reduction in water use when measured against the baseline period.
(2) Declaration. The city council shall declare a water shortage response level one—water shortage watch condition by resolution when the city council determines, in its sole discretion that a declaration will help to avoid or lessen the impact of an impending water supply shortage. The types of events which may prompt the city council to declare a water shortage response level one—water shortage watch condition may include, among other factors, a finding that the city’s wholesale supplier or metropolitan experiences shortages in their imported water supply, or must remove water from storage to meet normal demands.
(3) Public awareness/education. During a water shortage response level one—water shortage watch condition, the city will increase its public awareness and education efforts of water use restrictions and measures as outlined in this article.
(b) Response level two—Water shortage alert condition. (1) It is the intent of response level two to achieve up to a twenty (20) percent reduction in water use when measured against the baseline period.
(2) Declaration. The city council shall declare a water shortage response level two—water shortage alert condition by resolution when response level one actions have been taken, but the city council determines, in its sole discretion, that there are still insufficient supplies available to meet anticipated demands. The city council may then determine that the actions outlined in this section are necessary.
(3) In addition to the water use restrictions and measures identified in subsection (a), the following restrictions and measures shall be applicable:
(A) Irrigating landscape with potable water shall be limited in frequency as determined necessary by the city council by resolution.
(B) Irrigating landscapes shall not exceed ten (10) minutes per station. This provision does not apply to irrigating landscapes using water efficient devices including, but not limited to, drip-micro-irrigation systems and stream rotor sprinklers.
(C) Operating irrigation systems that result in water not being applied to the landscaped area by virtue of any or all of the following: excessive over spray, misting, over pressurization, misaligned or tilted spray heads, or any other malfunction or out-of-adjustment condition, is prohibited. (D) Water from a construction meter or water truck for irrigation purposes must be applied between the hours of 6:00 p.m. and 10:00 a.m. Note: if the city is notified in writing that initial landscape materials will be adversely affected by these restrictions, the city may establish a reasonable schedule for initial irrigation. The city has the right to inspect all construction sites using water from a city construction meter for the efficient use of water. (c) Response level three—Water shortage critical condition. (1) It is the intent of response level three to achieve up to a forty (40) percent reduction in water use when measured against the baseline period.

(2) The city council shall declare a water shortage response level three—water shortage critical condition by resolution when response level two actions have been taken, but the city council determines, in its sole discretion, that there are still insufficient supplies available to meet anticipated demands. The city council may then determine which actions listed below are necessary by resolution.
(3) In addition to water use restrictions and measures identified in subsections (a) and (b), the following requirements shall be applicable as determined by resolution:
(A) Maintaining ornamental lakes, ponds, or fountains is prohibited, except to the extent needed to sustain aquatic life, provided that such aquatic life is of significant value and have been actively managed within the water feature prior to declaration of a water shortage response level under this policy; (B) A pool or spa must be covered during non-use periods; (C) Any washing of vehicles must be done at commercial car washes or by mobile high pressure/low volume commercial services that recycle water;
(D) Annexations to the city’s water service area will be suspended; (E) Other water uses may be prohibited as determined by the director, after public notice to customers; and (F) No new potable water service shall be provided, no new temporary meters or permanent meters shall be provided, and no statements of immediate ability to serve or provide potable water service (such as, “will serve” letters, certificates, or letters of availability) shall be issued. This does not apply when: (1) a valid, unexpired building permit has been issued prior to the level three declaration for the project; or (2) the project is necessary to protect the public’s health, safety and welfare.

This subsection (c)(3)(F) shall not be construed to preclude the resetting or turn on of meters to provide continuation of water service or to restore service that has been interrupted for up to a period of one (1) year. (d) Response level four—Water shortage emergency condition. (1) Prohibited uses of water in a water shortage response level four—Water shortage emergency condition. This level will achieve the maximum possible percentage reduction in water use from the baseline period. (2) Declaration. The city council shall declare a water shortage response level four—water shortage emergency condition by resolution when all response level three actions have been taken, but the city council determines, in its sole discretion, that there are still insufficient supplies available to meet anticipated demands. The city council may then determine that the actions outlined in this section are necessary. (3) Restrictions and rates. In addition to all prohibited uses of water identified in subsections (a) through (c), the city council may, in its sole discretion, adopt a resolution to impose additional restrictions or prohibitions on the use of water to achieve reductions from the baseline period, or make additional adjustments to the water rates based on the city’s increased costs to provide water to its customers. (Ord. No. 2008-30(R), § 2, 10-22-08; Ord. No. 2009-16, § 3, 6-3-09; Ord. No. 2009-28, § 3, 1-6-10; Ord. No. 2015-12R, § 2, 6-10-15)

In accordance with the department’s emergency response plan and at the direction of the city manager, the director may determine that a sudden event has diminished, or threatens to significantly diminish, the reliability or quality of the city’s water supply. The director may declare a catastrophic water supply shortage and impose whatever emergency water allocation or conservation actions are deemed necessary, in the director’s professional judgment, to protect the reliability and quality of the city’s water supply, until the emergency passes, or until the city council may be convened to adopt a resolution or declaration of emergency, or to take other action. (Ord. No. 2008-30(R), § 2, 10-22-08)

Sec. 31-234. Notification.
(a) When a water shortage response level one—water shortage watch condition, a water shortage response level two —water shortage alert condition, a water shortage response level three—water shortage critical condition, a water shortage response level four—water shortage emergency condition, or a sudden catastrophic water supply shortage is declared, the city shall: (1) prior to the declaration provide notice of a public hearing, pursuant to California Water Code Section 352; and (2) after the declaration, publish the water shortage level in a local newspaper of general circulation, Resolution No. 2026-67

Quantifying Regional Self-Reliance and Reduced Reliance on Water Supplies from the Delta Watershed

Public Review Draft 1
1 Quantifying Regional Self-Reliance and
Reduced Reliance on Water Supplies
from the Delta Watershed

1.1 Background
Under the Sacramento–San Joaquin Delta (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.

Appendix C of the 2025 Urban Water Management Plan Guidebook (2025 Guidebook) states that an urban water supplier that anticipates participating in or receiving water from a proposed project, such as a multiyear 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 Urban Water Management Plans (UWMPs) beginning in 2015 that can then be used in the covered action process to demonstrate consistency with Delta Plan Policy Water Resources Policy 1 Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance (WR P1) (23 California Code Regulations (CCR) § 5003).

The City of Escondido (City) is an urban water supplier that anticipates receiving a blend of Delta water through its imported water purchased from the San Diego County Water Authority (Water Authority). Currently, the Water Authority purchases imported water from Metropolitan Water District of Southern California (MWD) which is a blend of State Water Project and Colorado River water. Therefore, the City has prepared this analysis to comply with the Delta Plan Policy WR P1.

The Delta Plan Policy WR P1 specifies the measures that must be taken by water suppliers under certain conditions to reduce their reliance on the Delta and improve regional self-reliance. In addition, the Delta Plan recommends that all water suppliers within the Delta watershed voluntarily implement the measures contained in WR P1 to reduce their reliance on the Delta and improve regional self-reliance. Delta Plan WR P1 identifies UWMPs as the tool to be used to demonstrate consistency with the state policy that requires suppliers who carry out or take part in covered actions to reduce their reliance on the Delta.

WR P1 details what is needed for a covered action to demonstrate consistency with reduced reliance on the Delta and improved regional self-reliance. WR P1 subsection (a) states:
(a) Water shall not be exported from, transferred through, or used in the Delta if all the following apply:
(1) One or more water suppliers that would receive water as a result of the export, transfer, or use have failed to adequately contribute to reduced reliance on the Delta and improved Resolution No. 2026-67

2 regional self-reliance consistent with all of the requirements listed in paragraph (1) of subsection (c);
(2) That failure has significantly caused the need for the export, transfer, or use; and (3) The export, transfer, or use would have a significant adverse environmental impact in the Delta.

WR P1 subsection (c)(1) further defines what adequately contributing to reduced reliance on the Delta means in terms of (a)(1) above:
(c)(1) Water suppliers that have done all the following are contributing to reduced reliance on the Delta and improved regional self-reliance and are therefore consistent with this policy:
(A) Completed a current Urban or Agricultural Water Management Plan (Plan) which has been reviewed by the California Department of Water Resources for compliance with the applicable requirements of Water Code Division 6, Parts 2.55, 2.6, and 2.8; (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 technically feasible 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 water supply, consistent with Water Code section 1011(a).

The analysis and documentation provided below include all the elements described in WR P1(c)(1) that need to be included in a water supplier’s UWMP to support a certification of consistency for a future covered action.

1.2 Demonstration of Regional Self-Reliance
The methodology used to determine the City’s improved regional self-reliance is consistent with the approach detailed in Appendix C of the 2025 UWMP Guidebook, including the use of narrative justifications for the accounting of supplies and the documentation of specific data sources.

Some of the key assumptions underlying the City’s demonstration of reduced reliance include:
 All data were obtained from the current 2025 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 its customers.
 Future projects that are covered actions requiring a certification of consistency with the Delta Plan were excluded from this analysis.

1.2.1 Baseline and Expected Outcomes
To demonstrate the expected outcomes for a reduced reliance on the Delta and improved regional self-reliance, a comparison to a baseline is needed. This analysis uses a normal water-year representation of 2010 as the baseline, which is consistent with the approach described in the 2025 UWMP Guidebook Appendix C. Population, demand, and supply data for the 2010 baseline were taken from the City’s 2005 UWMP.

Consistent with the 2010 baseline data approach, the expected outcomes for reduced Delta reliance and improved regional self-reliance for 2015, 2020, and 2025 were taken from the City’s 2010, 2015, and 2020 UWMPs, respectively. Expected outcomes for 2030-2045 are from the current 2025 UWMP. Documentation of the specific data sources and assumptions are included in the discussions below.

1.2.2 Service-Area Demands without Water Use Efficiency In alignment with the 2025 UWMP Guidebook Appendix C, this analysis uses normal water-year demands, rather than normal water-year supplies, to calculate the expected outcomes in terms of the percentage of water used. Normal water-year demands serve 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 the requirements of the UWMP 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 can calculate their embedded water use efficiency savings based on changes in forecasted per capita water use compared with the baseline. As explained in the 2025 UWMP 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 1 shows the results of this adjustment for the City. Supporting narratives and documentation for all the data shown in Table 1 are provided below.

1.2.3 Service-Area Demands with Water Use Efficiency
The service-area water demands shown in Table 1 represent the total municipal and industrial (M&I) water demands and non-potable demands for the City’s retail service area.

The M&I demand data shown in Table 1 were collected from the following sources:
 Baseline (2010): The City’s 2005 UWMP, Table 12 and Table 24  2015: The City’s 2010 UWMP, Table 3-9 and Table 5-4
 2020: The City’s 2015 UWMP, Table 3-6 (DWR Table 4-3R)  2025: The City’s 2020 UWMP, Table 4-2 (DW 4-1R)
 2030–2050: The City’s 2025 UWMP, Table 4-6 (DWR 4-3R)

1.2.4 Non-Potable Water Demands
The City owns and operates its own wastewater treatment and disposal facility, the Hale Avenue Resource Recovery Facility (HARRF). The HARRF produces secondary and tertiary treated effluent.

The tertiary treatment system has a design flow capacity of 9 MGD and is designed to comply with State Water Resources Control Board (State Water Board) Division of Drinking Water (DDW) criteria for disinfected tertiary recycled water.

The disinfected tertiary recycled water is used to meet recycled water demands. Currently, the City provides recycled water to 38 recycled water customers and Rincon del Diablo Municipal Water District (Rincon). The City’s recycled water program is permitted under Addendum No. 1 to the San Diego Water Board Order No. R9-2010- 0032. Excess tertiary-treated wastewater is dechlorinated and discharged to an onsite pond. The onsite pond is tested for total chlorine residual prior to batch discharge to the Pacific Ocean along with secondary-treated wastewater. The City began serving recycled water to customers in 2004. Details on the HARRF and recycled water supply are discussed in Chapter 6 of the City’s 2025 UWMP.

The non-potable water demand data shown in Table 1 represents recycled water demand estimates from for use in the City’s service area collected from the following sources:
 Baseline (2010): The City’s 2005 UWMP, Table 24
 2015: The City’s 2010 UWMP, Table 5-4
 2020: The City’s 2015 UWMP, Table 3-6 (DWR Table 4-3R)  2025: The City’s 2020 UWMP, Table 4-2 (DW 4-1R)
 2030–2050: The City’s 2025 UWMP, Table 4-6 (DWR 4-3R)

1.2.5 Potable Service-Area Demands with Water-Use Efficiency The “Potable Service Area Demands with Water Use Efficiency” was calculated by subtracting the “Non-Potable Water Demands” from “Service Area Demands with Water Use Efficiency.” Resolution No. 2026-67

 2015: The City’s 2015 UWMP, Table 2-2 (DWR Table 3-1R)  2020: The City’s 2015 UWMP, Table 3-6 (DWR Table 3-1R)  2025: The City’s 2010 UWMP, Table 3-2 (DWR Table 3-1R)  2030–2050: The City’s 2025 UWMP, Table 3-2 (DWR Table 3-1R)

1.2.7 Estimated Water-Use Efficiency Since Baseline
The estimated water use efficiency since baseline was calculated using potable service area demands with water use efficiency divided by service area population and then comparing with 2010 per capita water use.

1.2.8 Service-Area Water Demands without Water-Use Efficiency In Table 2 below, the service area demands with water use efficiency was added to the estimated water use efficiency since baseline to obtain the service area water demands without water use efficiency accounted for.

1.2.9 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 3 below shows expected outcomes for supplies contributing to regional self-reliance in terms of volume. Table 3 also represents efforts to improve regional self-reliance for the City’s entire service area and includes the total contributions of the City and its customers.

Supporting narratives and documentation for all the data provided in Table 3 are described below.

The City relies on local supplies and imported water to meet potable demands. Raw imported water is supplied by the Water Authority and the San Luis Rey Indian Water Authority (SLRIWA). In 2017, the City started receiving water from the SLRIWA through the Water Authority’s conveyance facilities. The City’s local surface water is collected from the San Luis Rey River watershed. The City plans to use these supplies to meet current and future demands under normal, single-dry, and five consecutive dry years. Currently, the City produces disinfected tertiary recycled water to sell to its customers and other agencies. The City has future projects in the works to expand upon recycled water treatment and use to offset imported water usage in the future.

1.3 Reliance on Water Supplies from the Delta
Watershed
MWD’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 (DMMs). MWD’s member agencies coordinate reliance on the Delta through their membership in MWD, a regional cooperative providing wholesale water service to its 26 member agencies, which includes the Water Authority, who the City receives supplies from. Accordingly, regional reliance on the Delta can only be measured regionally — not by individual MWD member agencies and not by the customers of those member agencies.

While MWD’s member agencies, and those agencies’ customers, indirectly reduce reliance on the Delta through their collective efforts as a cooperative, they do not control the amount of Delta water they receive from MWD. MWD manages a statewide integrated conveyance system consisting of its participation in the State Water Project; its Colorado River Aqueduct, including Colorado River water resources, programs, and water exchanges; and its regional storage portfolio.

Along with the State Water Project, Colorado River Aqueduct, storage programs, and MWD’s conveyance and distribution facilities, implementation of DMMs increase the future reliability of water resources for the region. DMMs provide system-wide benefits by decreasing the demand for imported water, which helps to decrease the burden on the district’s infrastructure, reduce system costs, and free up conveyance capacity to the benefit of all member agencies.

MWD’s costs are funded almost entirely from its service area, except for grants and other assistance from government programs. Most of MWD’s revenues are collected directly from its member agencies. Properties within MWD’s service area pay a property tax that is estimated to provide approximately 19% of the fiscal year 2026 annual budgeted revenues (Metropolitan Water District of Southern California, 2024). The rest of MWD’s costs are funded through rates and charges paid by MWD’s member agencies for the wholesale services it provides to them. Thus, MWD’s member agencies fund nearly all operations MWD undertakes to reduce reliance on the Delta, including Resolution No. 2026-67
Exhibit "A"

Demonstration of Reduced Delta Reliance

12 Colorado River programs, storage facilities, local resources programs, and conservation programs within MWD’s service area.

Because of the integrated nature of MWD’s systems and operations, and the collective nature of MWD’s regional efforts, it is infeasible to quantify each of MWD 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 MWD’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 MWD, that reduction does not equate to a like reduction of reliance on the Delta. Demands on MWD are not commensurate with demands on the Delta because most of MWD member agencies receive blended resources from the Delta and Colorado River systems. 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.

1.3.1 Programs Implemented by Metropolitan to Reduce Delta Reliance
As mentioned above, MWD, Water Authority, the City, and other local agencies invest in local sources to reduce reliance on the Delta. Because of the intricacies in the region’s large conveyance systems and the blend of supplies, Appendix 10 of MWD’s 2025 UWMP summarizes the various programs MWD has invested in to decrease reliance on the Delta.

Because of this infeasibility to separate out the individual member agency’s reduced reliance on the Delta, MWD has completed the analysis to demonstrate a regional wide reduction which is shown in Table 4 below.

1.4 Summary of Expected Outcomes for Reduced
Reliance on the Delta
As stated in WR P1(c)(1)(C), the policy requires that 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’s Delta reliance and regional self-reliance were developed using the approach and guidance described in 2025 UWMP Guidebook Appendix C published in March 2026.

The data used to demonstrate increased regional self-reliance in this analysis represent the total regional efforts of the City and its customers and were developed in conjunction with the Water Authority and MWD as part of the UWMP coordination process.

The following provides a summary of the near-term (2030) and long-term (2050) expected outcomes for the City’s regional self-reliance:
 Near-term (2030): normal water-year regional self-reliance is expected to increase by 24,230 AFY from the 2010 baseline; this represents an increase of about 56.3% of 2030 normal water year retail demands (Table 3)
 Long-term (2050): normal water-year regional self-reliance is expected to increase by 24,606 AFY from the 2010 baseline; this represents an increase of about 56.1% of 2050 normal water year retail demands (Table 3).

The results show that the City and its customers are measurably reducing reliance on the Delta and improving regional self-reliance.

The District anticipates making a draft UWMP and WSCP available for public review prior to the hearing, and the District’s Board of Directors will conduct a public hearing to receive input and consider adoption of the 2025 UWMP and WSCP.

The
adopted UWMP and WSCP will be submitted to the California Department of Water Resources, the County of San Diego, and the California State Library by July 1, 2026, as required by law. Information regarding the UWMP and WSCP update process, including the draft UWMP and WSCP when available, will be posted on the City’s website at www.escondido.gov once the public hearing date is identified.
