Floodplain Management Plan

The Comprehensive Floodplain Management Plan (FMP) is an overall strategy of programs, projects, and measures aimed at reducing the adverse impacts of flood hazards for Orange County unincorporated areas. The FMP identifies and addresses the impacts caused by flood hazards and provides specific mitigation measures to help protect the properties and their occupants. Orange County is currently in the process of creating its first FMP, and the National Flood Insurance Program will require Orange County to update its FMP every five years.

Please fill out our Repetitive Loss Area Analysis (RLAA) Survey.

StoryMap and draft FMP coming soon!
