Changes to Flood Insurance Rate Maps
The Federal Emergency Management Agency (FEMA) issued an updated Flood Insurance Study and associated digital Flood Insurance Rate Maps that were adopted by Martin County Board of County Commissioners and became effective on March 16, 2015. This study included analyses for rivers, streams, and creeks but did not include a coastal flood risk analysis.
In 2011, FEMA initiated a coastal flood risk study for east coast and central Florida. The study focused on the areas that affect Brevard, Indian River, Martin, and St. Lucie Counties. The study included an analysis of storm surge, wave hazards through modeling, and mapping.
The results were incorporated into an updated Flood Insurance Study (FIS) and digital Flood Insurance Rate Maps for these counties. The 5 volumes of the FIS report can be read via the links below.
FEMA combined its coastal risk study with its current flood maps, which became effective on February 19, 2020. To view what effect the flood maps may have on your property, view the FEMA Flood Zones Map.
