2025 Urban Water Management Plan

City of Pleasanton | Water Shortage Contingency Plan Public Draft | May 2026 1 EKI Environment & Water, Inc. 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.
