SACRAMENTO-SAN JOAQUIN DELTA REFORM ACT OF 2009
Zone 7 Water Agency
Reduce Reliance on the Delta
1 DRAFT | April 2026
The purpose of this document is to demonstrat e compliance with the Sacramento-San Joaquin Delta Reform Act of 2009. The Sacramento-San Joaquin Delt a Reform Act of 2009 is described below, followed by an analysis of Zone 7 Water Agency’s (Zone 7) reduced reliance in accordance with State protocols and expected outcomes for reduced reliance on the Delta.
1 SACRAMENTO-SAN JOAQUIN DELTA REFORM ACT OF 2009
Under the Sacramento-San Joaquin Delta Reform Act of 2009, state and local public agencies proposing a “covered action” in the Sacramento -San Joaquin Delta (Delta) must submit a written certification of consistency to the Delta Stewardship Council as to whether the covered action is consistent with applicable Delta Plan policies. Covered actions include a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting water from, or using water in the Delta.
Anyone may appeal a certification of consistency, and if the Delta Stewardship Council grants the appeal, the covered action may not be implemented until the agency proposing the covered action submits a revised certification of consistency, and either no appeal is filed, or the Delta Stewardship Council denies the subsequent appeal.
An urban water supplier that anticipates participating in or receiving water from a proposed covered action is required to provide information in thei r 2015 and subsequent Urban Water Management Plans (UWMPs) that can then be used in the covered action process to demonstrate consistency with Delta Plan Policy WR P1, Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance (WR P1).
WR P1 details what is needed for a covered action to demonstrate consistency with reduced reliance on the Delta and improved regional self-reliance. WR P1 subsection (a) states that:
(a) Water shall not be exported from, transferred through, or used in the Delta if all of the following apply:
(1) One or more water suppliers that would receive water as a result of the export, transfer, or use have failed to adequately contribute to reduced reliance on the Delta and improved regional self- reliance consistent with all of the requirements listed 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 adequa tely 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 Wa ter 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 me asurable 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).
Section 2
REDUCED RELIANCE ANALYSIS
Zone 7 Water Agency
Reduce Reliance on the Delta
2 DRAFT | April 2026
The analysis and documentation provided below include all of the elements described in WR P1(c)(1) that need to be included in a water supplier’s UWMP to support a certification of consistency for a future covered action. Including this document as an appendix in the 2015 and subsequent Urban Water Management Plans fulfills the requirements of WR P1 subsection (c)(1) Paragraph A. 2 REDUCED RELIANCE ANALYSIS
The data used in this analysis represent the regional efforts of Zone 7 to serve its customers in the Tri- Valley, including municipal and industrial (M&I) reta ilers (California Water Service, Dublin San Ramon Services District, City of Livermore, and City of Pleasanton), M&I direct retail customers, and untreated water customers. The analysis was coordinated with Zone 7’s retailers as part of the UWMP coordination process as described in the 2025 UWMP. In accordan ce with UMWP requirements, Zone 7’s retailers report their demand and supply data for their respective service areas in their respective UWMPs. This appendix reports demands on Zone 7 and supplies served by Zone 7. The retailers report their other sources of supplies used to supplement Zone 7 supplies in their UWMPs as applicable (e.g., recycled water, groundwater pumped by the retailer). Zone 7 provided the info presented here to the retailers so they can appropriately represent the nature of their wholesale supplies from Zone 7, and those supplies’ contributions to reduced Delta reliance.
The methodology used to determine Zone 7’s reduced Delta reliance and improved regional self-reliance is consistent with the approach detailed in Appendi x C of Department of Water Resources’ (DWR) Urban Water Management Plan Guidebook 2025 (Guidebook Appendix C) issued in January 2026, including the use of narrative justifications for the accounting of supplies and the documentation of specific data sources. General assumptions 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 wholesale level, focusing on Zone 7’s demands and sources of supplies served to the Tri-Valley.
• As described in Chapter 6 of the 2025 UWMP, Zo ne 7 is currently pursuing a number of water supply and storage alternatives to bolster water sy stem reliability while reducing reliance on the Delta. The future projects described in Chapter 6 and the demand management measures described in Chapter 9 fulfill the requirements of WR P1 subsection (c)(1) Paragraph B. For the purposes of the 2025 UWMP, a representative future water supply portfolio was selected; that portfolio is reflected in this analysis.
Tables 1 through 4 present the analysis of Zone 7’s reduced Delta reliance using DWR’s spreadsheet tool and fulfill the requirements of WR P1 subsection (c)(1 ) Paragraph C. Descriptions of the various inputs of the analysis are provided below:
• Baseline (2010) and 2015-2050 Conditions – The analysis uses a normal water year representation of 2010 as the baseline, which is consistent with the approach described in DWR’s Guidebook. Data for the 2010 baseline were taken from the 2010 UWMP (Table 9-11). To evaluate conditions relative to the baseline, actual conditions for 2015, 2020, and 2025 from Table 4-1 of the corresponding UWMPs are presented. Normal year projections for 2030 through 2050 from the 2025 UWMP are then subsequently used. In its 2025 UWMP, Zone 7 does not include operational storage—groundwater recharge a nd State Water Project (SWP) carryover—in its current or projected demands. To maintain consistency with base line and 2015 conditions, operational storage has been added to actu al (2025) and projected (2030-2050) demands presented in Zone 7’s 2025 UWMP.
• Service Area Water Demands with Wa ter Use Efficiency Accounted For – These values reflect Zone 7’s actual and projected water use, including water placed in storage as applicable.
Section 2
REDUCED RELIANCE ANALYSIS
Zone 7 Water Agency
Reduce Reliance on the Delta
3 DRAFT | April 2026
• Non-Potable Water Demands – This item includes untreated water demands, raw water losses, and water placed in storage.
• Water Supplies Contributing to Regional Self-Reliance — Water Use Efficiency – This amount is calculated by DWR’s spreadsheet tool based on Zone 7’s baseline demand, actual demands, and expected future demands. The value shown is the reduction in per capita wate r demand from the baseline (2010) multiplied by the projected population for each. Because the Tri-Valley has successfully reduced potable water demands over time, conserved water is contributing significantly to Zone 7’s regional self-reliance.
— Conjunctive Use Projects – Zone 7’s use of operational storage in the Main Basin is included here. The Main Basin is recharged with SWP water and local Arroyo Valle water.
This water is locally available for use during normal operations, drought, and emergencies.
— Local and Regional Water Supply and Storage Projects – This includes actual use and future projected use of local Arroyo Valle water.
— Other Programs and Projects that Contribute to Regional Self-Reliance – As discussed in Chapter 6 of the 2025 UWMP, Zone 7 has in cluded Sites Reservoi r (2,185 acre-feet per year [AFY] of average yield) as a representative future supply. As stated in a letter from the Delta Stewardship Council to the Site s Project Authority on May 2, 2018, “Sites Reservoir would be located upstream from the Delta, outside the legal Delta boundary” and “does not meet the definition of a covered action”; consequently, Sites Reservoir has been categorized as a water supply contributing to regional self-reliance. • Water Supplies from the Delta Watershed
— CVP/SWP Contract Supplies – Zone 7 derives a large portion of its supplies from the SWP system, as reflected in the analysis.
— Other Water Supplies from the Delta Watershed – SWP carryover water and actual recovered water from the Kern County groundwater banks delivered through the Delta have been included here. Note that future projections do not include water from the banks because that supply is not part of normal year operations.

3 EXPECTED OUTCOMES FOR REDUCED RELIANCE ON THE DELTA
As stated in WR P1(c)(1)(C), th e policy requires that , commencing in 2015, UWMPs include expected outcomes for measurable reduction in Delta reliance a nd 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 following provides a summary of the near-term ( 2030) and long-term (2050) expected outcomes for Zone 7’s Delta reliance and regional self-reliance ba sed on the assumptions described in the previous section and DWR’s analysis tool. The results show that Zone 7 is measurably reducing reliance on the Delta and improving regional self-reliance, based on the pe rcentage of Zone 7’s water supplies from the Delta Watershed.
Expected Outcomes for Regional Self-Reliance
Near-term (2030) – Normal water year regional self-reliance is expected to increase by approximately 35,100 AFY from the 2010 baseline (see Table 3). Conserved water and conjunctive use project water are the major sources of this increase. Long-term (2050) – Normal water year regional self-reliance is expect ed to increase by approximately 49,900 AFY from the 2010 baseline (see Table 3). Conserved water and conjunctive use project water are major contri butors to this increase, supplemented by Sites Reservoir and local surface water.
Expected Outcomes for Percent of Water Supplies from the Delta Watershed Near-term (2030) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by 40 percent relative to the 2010 baseline (see Table 4). Long-term (2050) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by 46 percent relative to the 2010 baseline (see Table 4).

INTRODUCTION
The City of Pleasanton (Pleasanton or City) has prepared this Water Shortage Contingency Plan (WSCP) in conjunction with the 2025 Urban Water Management Plan (UWMP) per California Water Code (CWC) Section (§) 10632. Water shortages occur whenever the available water supply cannot meet the normally expected customer water use. Water shortages can be attributed to various causes , such as climate change, drought, regulatory action, emergency, and/or catastrophic events. Shortage conditions could occur at any time and may, or may not, be foreseen. The City intends for this WSCP to be dynamic such that it may assess response action effectiveness and adapt to emergencies and catastrophic events.
This WSCP describes Pleasanton’s strategic plan to prepare for and respond to water shortage conditions and to guide the City in preventing water service disruptions. Further, the WSCP aims to ensure adequate supplies of water are available to meet the needs of the public and to further protect public health, safety, and welfare, consistent with Chapter 9.30 of the Pleasanton Municipal Code (PMC). The WSCP is also meant to prevent waste of water, unreasonable use of water, and unreasonable methods of water use.
Engrained in this plan is the City’s acknowledgement of water as a scarce natural resource that requires careful management, not only in times of drought but at all times.
This WSCP provides the following prescriptive elements:
• Water Supply Reliability Analysis (Section 1): Summarizes the City’ s water supply analysis and reliability and identifies the key issues that may trigger a shortage condition. • Annual Water Supply and Demand Assessment (AWSDA) Procedures (Section 2): 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. • Six Standard Shortage Levels (Section 3): Establishes water shortage levels to clearly identify and prepare for shortages.
• Shortage Response Actions (Section 4): Describes the response actions that may be implemented or considered for each level to reduce gaps between supply and demand as well as minimize social and economic impacts on the community.
• Communication Protocols (Section 5): Describes communication protocols under each level to ensure customers, the public, and local government agencies are informed of shortage conditions and requirements.
• Compliance and Enforcement (Section 6): Defines compliance and enforcement actions available to administer demand reductions.
• Legal Authorities (Section 7): Lists the legal documents that grant the City the authority to declare a water shortage and implement and enforce response actions. • Financial Consequences of a WSCP (Section 8): Describes the anticipated financial impact of implementing water shortage levels and identifies mitigation strategies to offset financial burdens.
• Monitoring and Reporting (Section 9): Summarizes the monitoring and reporting techniques to evaluate the effectiveness of shortage response actions and overall WSCP implementation.
Results are used to determine if shortage response actions should be adjusted. • WSCP Refinement Procedures (Section 10): Describes the factors that may trigger updates to the WSCP and outlines how to complete an update.

• Special Water Feature Distinction (Section 11): Defines considerations and definitions for water use for decorative features versus pools and spas.
The WSCP has been prepared in general accordance with the format suggested by the California Department of Water Resources (DWR) in the 2025 UWMP Guidebook and incorporates standardized DWR 2025 UWMP tables for WSCPs, consistent with the UWMP Act and CWC §10644(a)(2), which states:
“The plan, or amendments to the plan, submitted to the department … shall include any standardized forms, tables, or displays specified by the department".
In addition, tables and figures beyond DWR’s standard set are included as appropriate to provide further context. To distinguish content related to DWR’s standardized tables, the companion DWR table number is included in table titles throughout the Plan for accessible cross-reference. 1 WATER SUPPLY RELIABILITY ANALYSIS
Per CWC §10635(a-b), as part of UWMPs, every urban water supplier in California is required to assess the reliability of its water service to its customers during normal, dry, and multiple dry water years. Th e assessment compares the total water supply sources available to the supplier with the long -term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. Additionally, suppliers are required to address supply risks under a severe near-term drought period (i.e., 2026-2030) as a Drought R eliability Assessment (DRA). Both the near-term DRA and long-term supply reliability assessment consider plausible hydrological and regulatory variability, infrastructure capacity, climate conditions, and other factors that affect water supply and demand.
Sections 6 and 7 of the City’s 2025 UWMP present the City’s water supply sources and reliability, respectively. For potable supply, Pleasanton currently relies exclusively on Zone 7 Water Agency (Zone 7), the Tri-Valley’s regional wholesale water supplier. Thus, the City’s water supply reliability is fundamentally linked to Zone 7’s. For Zone 7, a water shortage condition occurs when the available supply of potable water cannot meet its retailers’ water demands for human consumption, sanitation, fire protection, and other beneficial uses. Besides the City, Zone 7’s retailers include California Water Service -Livermore District, the City of Livermore (Livermore), and Dublin San Ramon Services District (DSRSD).
Zone 7’s 2025 UWMP indicates the ability to meet retailer demands during five -year droughts in 2030, 2035, and 2040. However, beginning in 2045, Zone 7 is projecting a 14% shortfall for the last year of a drought lasting five consecutive water years . Because the City anticipates the ability to access its full groundwater pumping quota (GPQ) of 3,500 acre-feet per year ( AFY) will be restored through the Joint Groundwater Project, the assessment of future water supply reliability assumes that the City will rely upon groundwater to meet 3,500 AFY of its potable demands in each year of a five-year drought through 2045 and that the remaining balance will be met through Zone 7 supply purchases. For the fifth year of a five - year drought in 2045, the projected 14% r eduction in Zone 7 supply availability translates to a 10% shortfall for the City.
The analysis associated with this WSCP was developed in the context of Zone 7’s water supply sources and reliability. In some cases, the City and Zone 7 may be able to foresee a water shortage, but the water shortage may also be caused by an unforeseen sudden or emergency event. Statewide water supply conditions, changes in groundwater levels, and actions by other agencies may impact Zone 7’s available water supply. In general, Zone 7’s water supply conditions may be affected by the following:
• State Water Project (SWP) supply allocations and storage levels; • Vulnerability of the Sacramento-San Joaquin Delta to seismic events, changing environmental and regulatory requirements, and climate change; and

• Salts, nutrients, or contaminants in the groundwater basin. 2 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES
Beginning July 1, 2022, CWC §10632.1 requires water suppliers to submit an Annual Water Supply and Demand Assessment (AWSDA) and an Annual Water Shortage Assessment Report to DWR. The AWSDA is used to evaluate near -term water supply reliability for the upcoming fiscal year so that the City can prepare logistically and financially for any anticipated water supply constraints, as well as enact appropriate shortage response actions in a timely manner.
This section provides the procedures for the City to conduct its AWSDA, which will inform the City’s Annual Water Shortage Assessment Report and assist the City with planning for potential water supply shortages, including details of the decision -making process , key data inputs, and the steps the City may take to declare a water shortage emergency based on the level of shortage (Section 3) and implement water shortage response actions (Section 4). Given the City’s reliance on water from Zone 7, the City develops its AWSDA using Zone 7’s “Annual Review of the Sustainable Water Supply Report” (Annual Sustainability Report).
2.1 Decision-Making Process
To consistently produce its AWSDA , the City uses the decision-making process described in this section and may adjust and improve the process as needed.
The City’s Projection Team, consisting of the Utilities Planning Manager and the Assistant Director of Environmental Services and Utilities, is responsible for preparing/approving the City’s AWSDA and Annual Water Shortage Assessment Report and submitting them to DWR by July 1 st of each year. Staff gathers key data inputs and conducts the assessment in accordance with Section 2.2. In April, the Projection Team finalizes the assessment based on Zone 7’s Annual Sustainability Report. The AWSDA and Annual Water Shortage Assessment Report is presented to the Assistant Director of Utilities and Environmental Services, or designee, for review and approval. If the AWSDA concludes that available water supply is sufficient to meet expected demands for the current year and one subsequent dry year, no further action is required.
To conduct the AWSDA and prepare the Annual Water Shortage Assessment Report, the Projection Team follows the schedule of activities shown in Table 1. Due to year-to-year variations in hydrologic conditions, the timeframes shown in the tables are approximate and may be adjusted as needed. The City intends to implement shortage response actions to effectively address anticipated water shortage conditions in a timely manner while complying with the State’s reporting requirements.

If the AWSDA concludes that available supply will not meet expected demands, the Projection Team coordinates with the City’s Environmental Services Manager and Director of Public Works , collectively referred to as the Water Shortage Response Team (WSR Team). The WSR Team presents the finalized assessment to the City Council, along with recommendations on water shortage condition determination and actions. Recommended actions may include declaration of a water shortage emergency, declaration of a water shortage stage, and water shortage actions.
Based on the findings of the AWSDA, the City Council determines if a water shortage condition exists and, if needed, adopts a resolution declaring a water shortage emergency and an associated water shortage stage and authorizing water shortage actions. The WSR Team then prepare s the City’s Annual Water Shortage Assessment Report, incorporating City Council determinations and approved actions. The schedule of decision-making activities is provided in Table 2. The timeframes and activities shown in the table are approximate and may be adjusted as needed.

2.2 Data and Methodologies
The State requires that the AWSDA evaluate supplies and demands for, at a minimum, the current year and one subsequent dry year to determine water supply reliability. The City uses planned water supply and demand for the current year and a subsequent dry year for AWSDA reporting. In planning for water supplies, the following factors are considered as applicable and appropriate:
1. Zone 7 water supply availability
2. Hydrological conditions
3. Regulatory conditions
4. Contractual constraints
5. Water quality conditions
6. Groundwater well production limitations
7. Infrastructure capacity constraints or changes
8. Capital improvement project implementation
When describing water supply sources for the AWS DA, the City generally uses Section 6 (Water Supply Characterization) of the 2025 UWMP, including the supply projections. If supply sources and projections differ between the AWSDA and the UWMP, the City provides an explanation for the difference.
City of Pleasanton | Water Shortage Contingency Plan
Public Draft | May 2026
6 EKI Environment & Water, Inc.
The City uses planned unconstrained water demands as input to the AWSDA for the current year and the following one dry year. Unconstrained water demands are customer demands where no water conservation measures are in effect. In planning for water demands, the City considers the following factors, as applicable and appropriate:
1. Weather conditions
2. Water year type
3. Population changes (e.g., due to development projects)
4. Anticipated new demands (e.g., changes to land use)
5. Pending policy changes that may impact demands
6. Infrastructure operations
Similarly, when describing water demands for the AWSDA, the City generally uses Section 4 (Water Use Characterization) of the 2025 UWMP, including the demand projections. If the demand projections differ between the AWSDA and the UWMP, the City provides an explanation for the difference.
In preparing the AWSDA, Pleasanton uses the following assessment methodology and criteria to evaluate the City's water supply reliability for the current year and following one dry year. • The City uses a spreadsheet to plan for current year and future year supply and demands.
Planned supply and demand inputs are entered into the spreadsheet in annual increments. As needed, the increments may be revised to monthly or seasonal periods to more closely evaluate specific conditions and needs.
• Supply and demand are compared to determine the City’s water supply reliability in the current year and the following one dry year. The City’s water supply is deemed reliable if it can meet planned water demands in both the current year and the following dry year. If water supply cannot meet planned water demands in the current year or the following dry year, the extent of the water shortage condition is determined, and the City prepares response actions in accordance with this WSCP.
• Findings from the AWSDA are presented to City Council for consideration, along with recommendations for action.
3 SIX STANDARD WATER SHORTAGE LEVELS
To provide a consistent regional and statewide approach for conveying the relative severity of water supply shortage conditions, the State has established six standard water shortage levels that correspond to progressive reductions of up to 10, 20, 30, 40, 50%, and greater than 50% from the normal reliability condition. Each shortage condition should correspond to additional actions water suppliers would implement to meet the severity of the impending shortages.
A water supplier may use its own shortage levels if a crosswalk is included relating its existing shortage levels to the six standard levels ; however, the City’s stages align with the State’s, as described in P MC §9.30.060 and as indicated in Table 3.

PMC Chapter 9.30 includes stages that call for voluntary and/or mandatory water conservation to “reduce the consumption of water over an extended period of time, thereby extending the available water required for the city's customers while reducing the hardship to the greatest extent possible on or to the city and on or to the general public.” Stages of action are dependent on the total amount of water supplied to the city by Zone 7 and the amount of water the City can pump out of the groundwater basin from its own wells.
4 SHORTAGE RESPONSE ACTIONS
CWC §10632 (a)(4) requires shortage response actions that align with the defined shortage levels.
Pleasanton’s shortage response actions consist of a combination of demand reduction, supply augmentation, and operational changes. The specific suite of response actions implemented depends on the event that precipitates a water shortage stage, the time of the year the event occurs, the water supply sources available, and the condition of the City’s water system infrastructure. For each response action, the City has estimated the extent to which the action will reduce the gap between supply and demand.
The City tracks progress toward water use reduction goals during drought by comparing monthly water production for the same month in the most recent non -drought year to obtain a percent reduction. The City will increase or decrease its public outreach efforts based on observed use reduction . The City considers shortage response actions as tools for responding to water shortage conditions.
4.1 Supply Augmentation
The City’s normal supply portfolio remains purchased treated water from Zone 7 and local groundwater.
During shortages, the City coordinates with Zone 7 on supply conditions and under extreme shortage conditions, may request to expand its GPQ from Zone 7, as indicated in Table 4.

4.2 Demand Reduction
The City may request that its customers reduce their water demands in response to any water shortage stage through PMC §9.30. 080. During water shortage conditions, the City plans to reduce demand by implementing these actions, shown in Table 5. The table organizes demand reduction actions by water shortage stage (only in the stage when first implemented, as the City will continue to use these actions in higher stages unless otherwise noted). For each demand reduction action, the table identifies the estimated shortage gap re duction associated with implementing the action and indicates whether the City uses compliance actions such as penalties, charges, or other enforcement.
4.3 Operational Changes
During shortage conditions, system operations may be adjusted to optimize use of available supplies and further reduce demand. Examples of operational changes that the City may implement during a water shortage include:
• More frequent monitoring of water meters and customer water usage • Decreasing line flushing
• Expanding a public education campaign
• Increasing water waste patrols and enforcement
Some of these measures are also included above in Table 5 as they would either directly or indirectly reduce demand.
For a specific emergency event, the City can adjust water operations staff schedules such that rotating shifts cover the duration of the emergency if necessary. The City also has emergency interties with DSRSD

4.4 Additional Mandatory Restrictions
The City defines wasteful water use as a violation of water service and enforces the restrictions listed below under PMC §14.04.060 and related code provisions. The City’s current definitions of wasteful water include:
1. Use of potable water between 9:00 a.m. and 6:00 p.m. to irrigate grass, lawns, groundcover, shrubbery, crops, vegetation, and trees, with the exception of hand watering and drip irrigation.
2. The application of potable water to outdoor landscaping in a manner that causes runoff such that water flows onto adjacent property, non-irrigated areas, private and public walkways, roadways, and/or parking lots or structures.
3. Use of potable water to irrigate outdoor landscaping during and within 48 hours after measurable rainfall.
4. Use of potable water to wash down sidewalks, walkways, driveways, parking lots, open ground or other hard surface areas by the direct application of water thereto, unless needed for health or safety reasons.
5. Use of potable water in non-recirculating decorative ponds, fountains and other water features, with the exception of child water-play features.
6. Allowing potable water to escape from breaks within the person or consumer’s plumbing system for more than eight hours after the person or consumer is notified or discovers the break.
7. Use of potable water for outdoor landscaping through a dedicated irrigation meter within the city’s recycled water use area unless exempted by the director of operations and water utilities for existing water customers, or city engineer for new development.
8. Any use of potable water in violation of the CWC, including, but not limited to, the use of potable water on non-functional turf.
4.5 Emergency Response Plan
The shortage stages in Table 3 apply to both foreseeable and unforeseeable water supply shortage conditions. For catastrophic events, the City will implement the Water Emergency Response Plan (ERP) and coordinate emergency declarations and response actions with City leadership and Zone 7.
The City’s Water ERP specifies that the City Council, the Director of Emergency Services (City Manager), and the Director of Public Works have the authority to proclaim a Local Water Emergency. In a water emergency, the City would activate a Water Emergency Operations Center (WEOC), with partial or full staffing dependent on the magnitude of the event. WEOC and other emergency support staff and departments would typically work under the direction of the Director of Emergency Services (i.e., the City Manager). As defined in the City’s Water Management Plan, if there were a major failure of supply, storage or facility distribution, a declaration of mandatory water use restrictions would be necessary in designated affected areas (expected reduction would vary in response to the specific situation).
The City will also follow the lead of Zone 7, or the State of California, during a major catastrophe or drought period. When Zone 7 announces a curtailment in water deliveries, the City will assess the impact on the City supplies and determine its water sh ortage level. The City will monitor the situation closely, both from a supply and demand perspective, and carefully select the appropriate shortage response actions to close the gap between anticipated supplies and demand. The City will move from one stage to the next if the situation worsens and will reduce restrictions when it subsides. To provide supplies during
City of Pleasanton | Water Shortage Contingency Plan
Public Draft | May 2026
13 EKI Environment & Water, Inc.
an emergency, the City has two interties with DSRSD and one intertie with Livermore. Per agreements with DSRSD and Livermore made in 1996 and 2011, respectively, the City can receive from each agency a reasonable quantity of water required during the emergency.
The City has mutual aid agreements with the San Francisco Public Utilities Commission (SFPUC), Livermore, DSRSD, and Zone 7. The City also participates in the Water/Wastewater Agency Response Network (WARN), a statewide public utility mutual assistance organization . After exhausting its own resources, the City can call on these neighboring agencies for aid.
4.5.1 Interrupted Supply from Zone 7
If imported deliveries are interrupted, the City will coordinate with Zone 7 on available groundwater and stored supplies and implement applicable shortage stage actions immediately.
Zone 7 has emergency generators (both portable and dedicated) at strategic locations in preparation for a regional power outage. These generators would allow both the Del Valle Water Treatment Plant and the Patterson Pass Water Treatment Plant to continue operating even under a power outage. Assuming no interruptions in surface water supply, Zone 7 would be able to provide continued service to all treated water contractors. If necessary to meet demand, Zone 7 would also operate groundwater wells, which have either a dedicated generator in place or have the necessary hook -ups to receive power from a portable generator. If the power failure were to occur during the high -demand summer season, Zone 7 may be unable to meet hourly peak demands throughout the trans mission system. Zone 7 would work closely with the City and other retailers to manage demands to minimize impacts.
4.5.1.1 Unavailable SWP Water
Zone 7 , and therefore Pleasanton, relies heavily on the SWP for water supply. If SWP supplies are unavailable, the City will rely on available alternative deliveries and groundwater, evaluate projected deficits, and escalate stage actions as needed.
Under this scenario and under current conditions, Zone 7 estimates that it would be able to make full deliveries to the retailers during non -summer months using a combination of groundwater and water stored in Lake Del Valle. During the peak demand of the summer months, however, Zone 7 will need to reduce deliveries to its retailers, including the City. Zone 7’s analysis shows that Zone 7 has sufficient groundwater supply and pumping ability to serve the indoor water use needs of the service area over a one-year period; the availability of water supply for outdoor water use during the summer months will depend on the amount of water available in Lake Del Valle. Depending on timing and degree of recovery, the City may activate one of the water shortage levels in Section 3.
4.5.1.2 Unavailable Zone 7 Water
If one or more Zone 7 turnouts are unusable, the City will reroute available supplies where feasible and prioritize service reliability while implementing shortage response measures.
4.5.2 Area-Wide Electrical Power Failure
During prolonged power outages, the City will rely on backup power and emergency operations where available, prioritize critical facilities, and maintain shortage response messaging. Additionally, the City could receive water from emergency interties with DSRSD and Livermore if necessary.
4.6 Seismic Risk Assessment and Mitigation Plan
CWC §10632.5(a) requires that UWMPs assess seismic risk and include a mitigation plan for the water system’s seismic vulnerabilities and allows for incorporating a Local Hazard Mitigation Plan (LHMP) to meet this requirement, if the LHMP addresses seismic risk. Along with DSRSD and the cities of Dublin and

Livermore, Pleasanton participated in development of the 2024 Tri-Valley LHMP Update (2024 LHMP), which addresses seismic risk . This WSCP incorporates th e 2024 LHMP by reference. The Federal Emergency Management Agency (FEMA) approved the 2024 LHMP. Direct links to the 2024 LHMP are included below, along with instructions on how to navigate to the 2024 LHMP via Pleasanton’s website. • Direct link – Volume 1 (Planning Area-Wide Elements):

On the “Community and Economic Development” page, scroll down to the “Codes, Guidelines and Plans” section. The Tri- Valley Hazard Mitigation Plan is listed under the “Specific Plans.” The City’s water facilities, as well as Zone 7’s, have been constructed in accordance with the applicable building codes to minimize potential damage during an earthquake. Additionally, approximately 85 % of the City’s water infrastructure has been earthquake reinforced, and no area within the service area is solely dependent on non -earthquake reinforced infrastructure. The City has multiple turnouts from Zone 7; so, if one is damaged during an earthquake, the City can use the remaining turnouts to continue receiving water supply from Zone 7. Furthermore, the pipelines were built in a looped arterial design to ensure there is more than one route for water flow.
5 COMMUNICATION PROTOCOLS
In the event of a water shortage, the City must inform its customers, the public and interested parties, and local, regional, and state entities. This section addresses c ommunication protocols for foreseeable and unforeseeable events.
5.1 Communication for Foreseeable Events
For foreseeable conditions, the City initiates communication through the AWSDA decision process and City Council stage actions. Messaging includes the declared shortage stage and the required demand reduction actions from Table 5. If a water shortage emergency is anticipated, City staff coordinate interdepartmentally, with the region’s water service providers, and with Alameda County for the possible proclamation of a local emergency.
In a duly noticed meeting, the City Council receive s presentation of the current or predicted shortage as determined by the current AWSDA. The City Council determines if a water shortage emergency condition exists and the degree of the emergency, while considering the shortage response actions triggered or anticipated to be triggered by the shortage level. As necessary, the City Council acts on the water shortage emergency declaration and the associated shortage stage and response actions.
If the City Council declares a water shortage emergency, the Public Information Officer (PIO) and City staff coordinate to communicate with City customers and the public to inform them about the declared water shortage emergency, water shortage level, and authorized water use restrictions. The City may use any combination of the following outreach formats: newspaper publication, mailers, bill stuffers, newsletters, social media, its website, local radio, and press releases.
City staff communicate with the appropriate State agencies regarding the water shortage emergency when needed.
City of Pleasanton | Water Shortage Contingency Plan
Public Draft | May 2026
15 EKI Environment & Water, Inc.
5.2 Communication for Unforeseeable Events
For unforeseeable events such as infrastructure failure or wildfire impacts, communications will follow the Water ERP chain of command and provide frequent updates on service conditions, safety advisories, and stage-based demand reduction requirements.
In general, communications and notifications proceed along the chain of command at the direction of the Director of Emergency Services, with external communications managed by the PIO. The W ater ERP provides a list of relevant contacts for notification at local, regional, and state levels.
The PIO is the official spokesperson for the City and is responsible for establishing an information center and providing information for news media. In addition, the PIO maintains a list of contacts to disseminate information to the public, typically via electronic media, radio, television, or newspapers. 6 COMPLIANCE AND ENFORCEMENT
After City Council adopts a shortage stage, the City enforces applicable demand reduction actions and PMC restrictions through progressive compliance measures. Compliance expectations are communicated with the stage declaration and reinforced through billing notices, outreach, and targeted follow -up for high-use accounts.
When the City enacts mandatory reductions, customers are required to reduce water demands based on past use for the same billing period from the previous one to four years, as data is available. If insufficient historic usage information is available, then the City may base reductions on a combination of available data, per-capita water use targets, water usage from similar customer types, and other activity -specific water usage data. Customers can request adjustments to water use reductions by submitting a written request with supporting documentation within 30 days of receipt of the bill that is the subject of the adjustment request.
Customers exceeding required reductions are subject to excess use penalties and other enforcement actions authorized by City code and adopted schedules, as described in Table 6.

(b) Penalties are defined per PMC §9.30.100.
7 LEGAL AUTHORITIES
Per PMC Chapter 9.30, Pleasanton has legal authority to declare a water shortage and implement and enforce shortage response actions.
7.1 Declaration of Water Shortage
PMC Chapter 9.30 includes provisions for declaring a water shortage emergency, determining customer use reductions, water use regulations and restrictions, and compliance and enforcement. When a water shortage is determined, the City will coordinate with Zone 7, the region’s other water service providers, and the County for the possible proclamation of a local emergency in accordance with California Government Code, California Emergency Services Act (Article 2, §8558).
7.2 Proclamation of Local Emergency
In a duly noticed meeting, t he Pleasanton’s City Council will determine whether a water shortage emergency condition exists and, if so, the degree of the emergency and what regulations and restrictions should be enforced in response to the shortage. The City shall declare a water shortage emergency in accordance with CWC Division 1, Chapter 3,
§350, which states:
…The governing body of a distributor of a public water supply…shall declare a water shortage emergency condition to prevail within the area served by such distributor whenever it finds and determines that the ordinary demands and requirements of water consumers cannot be satisfied
City of Pleasanton | Water Shortage Contingency Plan
Public Draft | May 2026
17 EKI Environment & Water, Inc.
without depleting the water supply of the distributor to the extent that there would be insufficient water for human consumption, sanitation, and fire protection. 8 FINANCIAL CONSEQUENCES OF WSCP
This section describes the financial impacts of implementing the WSCP and mitigation actions needed to address these impacts.
8.1 Financial Impacts and Mitigation Action
During periods of water shortage and reduced customer consumption, the City anticipates its revenue will decrease due to reduced water demand. Meanwhile, the City anticipates its expenditures will increase due to implementing water conservation measures to cover costs associated with increased customer communication, expanded public outreach campaigns, enforcement staffing, operational adjustments, and program administration. To compensate for lost revenue and increased expenditures, the City may implement drought rates and pass through applicable wholesale shortage surcharges in accordance with adopted fee schedules.
8.2 Reporting Cost of Compliance with Excessive Water Use Prohibition during Drought Emergency
The City complies with CWC §10632 by implementing measures to prohibit excessive water use from customers. The City achieves c ompliance through implementation of its WSCP, PMC Chapter 9.30, and PMC §14.04.060. Costs are primarily related to added administrative tasks and enforcement , which include increased labor and contractor assistance . The total cost of compliance depends on the water shortage level and duration.
9 MONITORING AND REPORTING
From water supply sources to individual customer connections, the City’s water system is fully metered.
City staff can use data from meters to monitor for compliance and report progress . The City’s meters at its water sources (i.e., turnouts from Zone 7 and groundwater production wells ) provide a systemwide overview of water supply and demands. Further, most of the City’s customer accounts are connected to the Advanced Metering Infrastructure (AMI) system that allows for real-time monitoring. Approximately 300 of the City’s customer meters are not connected to AMI due to terrain challenges with connectivity .
The City may use metering information to assess progress in meeting its water shortage response objectives, as part of its meter management program.
During drought, Pleasanton staff compare expected/requested water use reductions to observed savings, track response action implementation, and report results through required monthly and annual reporting processes. City staff use monitoring results to inform recommendations for maintaining, escalating, or de- escalating shortage stages and to refine implementation assumptions for future assessments. 10 WSCP REFINEMENT PROCEDURES
This WSCP is an adaptive plan that is subject to refinements as needed to ensure that the City’s shortage response actions and mitigation strategies are effective and produce the desired results. Based on monitoring described in Section 9 and the need for compliance and enforcement actions described in Section 6, the City may adjust its response actions and modify its WSCP. The City may also seek input from staff and the public regarding the effectiveness of its WSCP and ideas for improvements.
City of Pleasanton | Water Shortage Contingency Plan
Public Draft | May 2026
18 EKI Environment & Water, Inc.
When a revised WSCP is proposed, the revised WSCP will undergo the process described in Section 12 for adoption by City Council and distribution to the County, Zone 7, and the public. 11 SPECIAL WATER FEATURE DISTINCTION
The City distinguishes and regulates special water features (e.g., decorative fountains and ponds ) separately from pools and spas. PMC §9.30.110 prohibits the use of water in non -re-circulatory ponds, fountains, and decorative water features during the time PMC Chapter 9.30 is in effect. 12 PLAN ADOPTION, SUBMITTAL, AND AVAILABILITY
This WSCP is adopted concurrently with the City’s 2025 UWMP, by separate resolution. Prior to adoption, a duly noticed public hearing was conducted. A copy of this WSCP will be submitted to DWR by July 1, 2026.
No later than 30 days after adoption, copies of this WSCP will be available at the City’s Operations Service Center and the Pleasanton Public Library . A copy will also be provided to the County and Zone 7. An electronic copy of this WSCP will also be available for public review and download on the City’s website.

Subject: Preparation of 2025 Urban Water Management Plan and Water Shortage Contingency Plan
Notice of Preparation of the 2025 Urban Water Management Plan and Water Shortage Contingency Plan
The City of Pleasanton (City) is currently in the process of preparing its 2025 Urban Water Management Plan (UWMP) and associated Water Shortage Contingency Plan (WSCP) as an update to the City’s 2020 UWMP adopted in June 2021. The UWMP is a planning document that reports, describes, and evaluates water deliveries, uses, conservation efforts, supply sources, and supply reliability. The WSCP defines various stages of water supply shortage based on supply conditions and identifies planned responses for each stage.
The Urban Water Management Planning Act (California Water Code §10608–10656) requires urban water suppliers to prepare and adopt an updated UWMP and accompanying WSCP every five years. All urban water suppliers (either publicly or privately owned) that provide water for municipal purposes (either directly or indirectly) to more than 3,000 customers or supply more than 3,000 acre-feet per year are subject to the Urban Water Management Planning Act. As an urban water supplier, the City is required to submit its 2025 UWMP and WSCP to the California Department of Water Resources (DWR) by July 1, 2026.
Coordination with other water management agencies/suppliers, public agencies (e.g., cities and counties), and community organizations in the region is an integral part of updating the City’s UWMP and WSCP. The City invites your agency’s/organization’s participation in this process. City staff are available to discuss the underlying assumptions used to prepare the plans (e.g., projected water demands, supply availability, and land uses, etc.) and other aspects.
The City will release draft versions of the 2025 UWMP and WSCP for public review and hold public hearings (anticipated in April and May 2026, respectively).
If you wish to contact the City about this review process, you may email staff at: [email protected]

Notice of Preparation of the 2025 Urban Water Management Plan and Water Shortage Contingency Plan
The City of Pleasanton (City) is currently in the process of preparing its 2025 Urban Water Management Plan (UWMP) and associated Water Shortage Contingency Plan (WSCP) as an update to the City’s 2020 UWMP adopted in June 2021. The UWMP is a planning document that reports, describes, and evaluates water deliveries, uses, conservation efforts, supply sources, and supply reliability. The WSCP defines various stages of water supply shortage based on supply conditions and identifies planned responses for each stage.
The Urban Water Management Planning Act (California Water Code §10608–10656) requires urban water suppliers to prepare and adopt an updated UWMP and accompanying WSCP every five years. All urban water suppliers (either publicly or privately owned) that provide water for municipal purposes (either directly or indirectly) to more than 3,000 customers or supply more than 3,000 acre-feet per year are subject to the Urban Water Management Planning Act. As an urban water supplier, the City is required to submit its 2025 UWMP and WSCP to the California Department of Water Resources (DWR) by July 1, 2026.
Coordination with other water management agencies/suppliers, public agencies (e.g., cities and counties), and community organizations in the region is an integral part of updating the City’s UWMP and WSCP. The City invites your agency’s/organization’s participation in this process. City staff are available to discuss the underlying assumptions used to prepare the plans (e.g., projected water demands, supply availability, and land uses, etc.) and other aspects.
The City will release draft versions of the 2025 UWMP and WSCP for public review and hold public hearings (anticipated in April and May 2026, respectively).
