In Progress

Summary of objective implementation status (achievements or progress over last year; significant delays or issues, etc.)

The Countywide Flood Risk Management (FRM) Assessment kicked off in Spring 2023 when HDR, Inc. was brought on as the consultant for this effort. The Assessment is designed to identify gaps and overlaps in flood risk management services across the county, to encourage collaboration, and to jointly develop recommendations for improving FRM services countywide. To date, the effort has produced a technical memo to aggregate existing information on current flood risk and flood risk management strategies by watershed in the county. Additionally, a partner kick-off meeting took place in August 2023, followed by several months of surveys and interviews with FRM partner agencies. Next steps include an in-person workshop for partner agencies and a final recommendations report that will be produced based on all input gathered during the assessment. Recommendations will help position the county for external funding and will inform future flood risk management efforts.
