To assist with the Hurricane Katrina and Rita recovery effort, the Department of Homeland Security, Federal Emergency Management Agency (FEMA), reevaluated and remapped the coastal flood hazards and flood elevations for the 14 communities located in Mississippi’s coastal counties.

The reevaluation and remapping effort resulted in detailed, updated, Digital Flood Insurance Rate Maps (DFIRMs) that can be used to determine where to build and to what elevation new buildings should be constructed to maximize the safety of residents. The new coastal remapping data was incorporated into the three countywide DFIRM projects for Hancock, Harrison and Jackson counties, which in fact, were in progress before Hurricane Katrina struck.

The project was performed as part of FEMA’s Flood Map Modernization (Map Mod) effort in partnership with the State of Mississippi through the Mississippi Emergency Management Agency (MEMA) and the Mississippi Department of Environmental Quality (MDEQ).

These preliminary flood hazard maps, or DFIRMs, were released in late fall 2007.
