RESOLUTION NO. 2026 – 6 RESOLUTION OF THE BOARD OF DIRECTORS OF THE IRVINE RANCH WATER DISTRICT RESCINDING RESOLUTION 2021-11 AND ADOPTING THE 2025 WATER SHORTAGE CONTINGENCY PLAN
The Urban Water Management Planning Act (California Water Code §§ 10610 et seq.) requires each urban water supplier’s urban water management plan (“ UWMP ”) to provide a water shortage contingency analysis. The Urban Water Management Planning Act requires that each urban water supplier update its UWMP at least once every five years. Irvine Ranch Water District (“ IRWD ”) initially adopted its Water Shortage Contingency Plan (the “ Plan ”) in 1987, through the adoption of Resolution No. 1987-52 amending IRWD’s Rules and Regulations, Section 15, then entitled “Prohibition of Water Wastage.” The Plan is an appendix to IRWD’s UWMP, and along with certain information in the UWMP, provides the water shortage contingency analysis required by Water Code § 10632. The Plan also serves as the resource and supporting document for the implementation of Rules and Regulations, Section 15, now entitled “Water Conservation and Water Supply Shortage Program and Regulations.” The Plan has been updated periodically, including most recently a version adopted on June 28, 2021 by Resolution No. 2021-11. IRWD prepared the 2025 Plan pursuant to the requirements of Water Code § 10632. The 2025 Plan was presented at IRWD’s June 22, 2026 meeting of the Board of Directors. The WSCP was revised to incorporate the findings of IRWD’s 2025 Water Reliability Study and updated seismic and hazard mitigation plans. It also incorporates WSCP rates, which were publicly noticed and adopted by the Board on June 23, 2025. The Board of Directors intends to update the Plan in compliance with Water Code § 10621. The Board of Directors of Irvine Ranch Water District therefore resolves as follows: 1. That Resolution No. 2021-11 dated June 28, 2021, is hereby rescinded. 2. That the Water Shortage Contingency Plan (2025) presented to the Board of Directors on June 22, 2025 is hereby adopted. 3. That the Water Shortage Contingency Plan (2025) will serve as a supporting document to Section 15 of the Rules and Regulations and to the UWMP. 4. That pursuant to Water Code § 10632(a)(8), in declaring any levels of shortage, the Board of Directors may adopt a water shortage contingency resolution in a
