O.8.3 Completed or Removed Mitigation Initiatives The following mitigation actions from the 2021 plan have been completed or are in progress and therefore are removed from this plan update. Mitigation: Coordinate with the County of Orange for opportunities to allow shared communication space on cell towers for IRWD. Shared space would allow for IRWD Supervisory Control and Data Acquisition (SCADA) radio communication only. ‒ Status: Completed. Mitigation: Identify additional back-up communication systems (such as satellite phones or radio) for purchase, to utilize if primary communication systems become unavailable. Ensure that coverage includes the entirety of the IRWD service area. Include annual training opportunities. ‒ Status: Completed. Mitigation: Implement and maintain both internal and external alert/warning systems to effectively communicate hazard threats to staff and customers. Include utilization of the alert/warning system in a regular training program. ‒ Status: Completed. Mitigation: Enhance phone system to support phone connectivity when people are working offsite through Voice over Internet Protocol (VoIP). ‒ Status: Completed. Mitigation: Prepare a Recycled Water Shortage Contingency Plan ‒ Status: Completed. Mitigation: Assess permanently elevating water-sensitive equipment and anchoring fuel tanks in Mitigation: Regularly check and maintain radar flood level gauges located in San Diego Creek. ‒ Status: Remove. This is part of preventative maintenance and does not need to be included here. Mitigation: Designate alternative locations for residual dirt and fill storage, away from the Michelson Yard ‒ Status: Complete in 2024. Expected to be completed in 2024 with alternative road access being developed into and out of Michelson Water Recycling Plant for use in the event of major flooding. Flood gates have also been implemented. This allows IRWD vehicles and equipment to continue to be staged at its normal location without having to be re-staged. Mitigation: Continue to monitor and track regulatory requirements and updates as they relate to hazardous materials storage and response actions. flood-prone locations. ‒ Status: Completed.
