Flood Information

Martin County participates in the National Flood Insurance Programs (NFIP) Community Rating System (CRS) as a result we are able to provide digital/online copies of the FEMA Flood Insurance Rate Maps (FIRM). This information is available through our FEMA Flood Zones Map. 

The County currently has a rating of class seven (7) within the program which equates to a 15% discount on flood insurance for structures located within a Special Flood Hazard Area.

Coastal Flood Risk Study

In Fiscal Year 2011, the Federal Emergency Management Agency (FEMA) initiated a coastal flood risk study for the East Coast Central Florida Study Area that affects Brevard, Indian River, Martin, and St. Lucie Counties. The results of that study will be incorporated into updated digital Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports for these counties.

In 2015, FEMA issued updated digital Flood Insurance Rate Maps (FIRMs) and an associated Flood Insurance Study report that were adopted by Martin County. This study included analyzes for rivers, streams, and creeks but did not include a coastal analysis.

FEMA recently released the Preliminary Flood Insurance Rate Maps (FIRMs) for the Coastal Flood Risk Study that are now available for review by the public. To view what effect the study may have on your property please select the “Preliminary Coastal Flood Risk Map” button.
