Orange County Water & Wastewater Multi-Jurisdictional Hazard Mitigation Plan 2024
Coordinate with SCE prior to any planned power outage to ensure generator capacity and time to pre-position supplies as needed. Maintain communications with SCE for duration of power outage. Utilize data from ongoing generator replacement projects to develop further wildfire and power outage mitigation projects, once above study results become available. Monitor changes/updates to building codes and seismic regulations to determine if IRWD-owned critical facilities may need seismic retrofits as they age and building codes are updated. If any IRWD-owned critical facility is determined to be seismically vulnerable, identify a plan to conduct structural retrofitting, including funding sources. As repair and rehabilitation needs are identified in vertical structural facilities, consider options that increase stability and resiliency as needed. Make improvements in accordance with current codes. Include assessment and mitigation of potential liquefaction conditions in the scope of any new building or infrastructure project. Develop and maintain Specific Hazard Response Plans (SHRPs) as vulnerabilities become apparent. Include SHRPS in regular training and exercise programs. Conduct an update of the IRWD Climate Adaptation and Energy Management Plan, formerly known as the Energy & Greenhouse Gas Master Plan. Seek funding opportunities to further study, plan and implement the IRWD potable reuse program. Continue to proactively monitor drought conditions or water conservation warnings issued by state agencies or regional water authorities. Implement the Kern Fan Groundwater Storage Project. The project develops water recharge and recovery facilities in the San Joaquin Valley Groundwater Basin to recharge, store, recover and deliver State Water Project water, Central Valley Project water, Kern River water available with existing right holders, and water from other sources when available.
