Draft 2025 Water Shortage Contingency Plan

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

The IRWD Communications Department maintains the IRWD website, writes the monthly e- newsletter, and posts regularly though IRWD social media channels. These various forms of communication provide an opportunity to convey information and implement mitigation actions specific to educating and informing the community regarding all hazards and ways to reduce impacts from the hazards.

Multiple mitigation actions are priority projects to expand IRWD capabilities. Examples of opportunities to expand capabilities include the following mitigation actions: Planning/Regulatory: Technical Communications Plan (Mitigation Action #2), Specific Hazard Response Plans (Mitigation Action #5), Energy and Greenhouse Gas Master Plan (Mitigation Action #7), Inflow and Infiltration Study (Mitigation Action #13), Cybersecurity Plan (Mitigation Action #20). Admin/Technical: Technical communications system (Mitigation Action #2), WEROC membership (Mitigation Action #6). Financial: Seek funding opportunities for potable reuse program (Mitigation Action #9), funding for seismic vulnerability evaluation (Mitigation Action #32). Education/Outreach: Specific Hazard Response Plans regular training and exercise programs (Mitigation Action #5), WEROC membership for communication and collaboration (Mitigation Action #6), coordination with police for IRWD-preferred response in localized flooding incidents (Mitigation Action #15), support customer cities in community outreach regarding hazardous materials (Mitigation Action #18), coordination with public safety agencies after wildfires (Mitigation Action #22), and explore opportunities for additional outreach programs (Mitigation Action #37).

MITIGATION STRATEGY

O.8.1 Mitigation Goals IRWD adopts the hazard mitigation goals developed by the planning team; refer to Section 4 . O.8.2 Mitigation Actions The internal development team reviewed the mitigation actions identified in the 2021 plan and the updated risk assessment to determine if the mitigation actions were completed, required modification, should be removed because they are no longer relevant, and/or should remain in the MJHMP update. Since many of the actions were relatively recent, IRWD identified the actions that were completed and removed those from the mitigation actions table. The remaining actions were kept in the plan, which are illustrated in Exhibit O-13, IRWD Mitigation Actions. This exhibit identifies the mitigation actions, including the priority, hazard addressed, cost, timeframe, and potential funding sources. Additional details regarding this information can be found in Section 4 . Cost estimates rely on a three tiered system, which include the following categories and corresponding dollar amounts: Low - <$500,000 | Medium - $500,001 - $2,000,000 | High - > $2,000,001 High
