HIGH PRIORITY
Build redundancy into the wastewater collection, treatment, disposal, and non-potable distribution system to mitigate major structural defects. Develop a technical communications plan to build redundancy and evaluate the cost/benefit and feasibility of different communications systems. Implement and maintain information sharing mechanisms/platforms for involved departments to utilize during a disaster response. Ensure the platform can be viewed on network devices and mobile devices, while maintaining data security. Maintain Water Emergency Response Organization of Orange County (WEROC) membership for communication and collaboration opportunities with regional water districts, including identification and implementation of mitigation actions with shared benefits. Evaluate dam improvements to increase resiliency in coordination with the Dam Safety Program and Implementation Plan. Continue to conduct geotechnical studies for geologic hazards on new construction projects when appropriate, to evaluate vulnerabilities for geologic hazards Develop a Cybersecurity Plan in coordination with a consultant to include a disaster recovery (DR) plan. Continue to conduct geotechnical studies to determine the potential for onsite landslides in any new construction project. Implement the Santiago Creek Dam Improvements Project. The proposed activity includes removal and replacement of the existing outlet tower, outlet works and spillway facilities, in accordance with recommendations from the DSOD.
