Draft 2025 Urban Water Management Plan

Orange County Water & Wastewater Multi-Jurisdictional Hazard Mitigation Plan 2024

IRVINE RANCH WATER DISTRICT ANNEX Irvine Ranch Water District (IRWD) is a participant (Member Agency [MA]) in the Orange County Water and Wastewater Multi-Jurisdictional Hazard Mitigation Plan (MJHMP). As a participant MA, IRWD representatives were part of the MJHMP planning process and served on the planning team responsible for the plan update; refer to Section 2 of the MJHMP. The base plan, including the Hazard Mitigation Plan (HMP) procedural requirements and planning process apply to IRWD. To comply with DMA 2000 requirements IRWD recently completed a single-jurisdiction Local Hazard Mitigation Plan (LHMP) that was adopted in 2021 (included as Appenix O-1). Instead of updating this plan, IRWD opted to join the MJHMP update process established by MWDOC. This annex supersedes the 2021 IRWD LHMP and details the hazard mitigation planning elements specific to IRWD. The annex also describes how IRWD’s risks vary from the planning area. This annex is not intended to be a standalone document but supplements the information contained in the base plan. All sections of the MJHMP, including the planning process and other procedural requirements, apply to and were met by IRWD. The base plan treats the entire county as the planning area and identifies which MAs are subject to a profiled hazard. The purpose of this annex is to provide additional information specific to IRWD with a focus on the risk assessment and mitigation strategies.
