Information For

The Federal Emergency Management Agency (FEMA) Region IV Office in Atlanta, Georgia, has undertaken a multiyear coastal engineering analysis and mapping effort. Through the analysis and mapping effort, FEMA Region IV will better identify, assess, and communicate hazards and risks associated with coastal flooding in the Southeastern U.S.

In recent years, FEMA performed flood hazard studies and produced new or updated digital Flood Insurance Rate Maps (FIRMs) and associated Flood Insurance Study (FIS) reports for many coastal counties. (To learn more about FIRMs and FIS reports, visit the FEMA Online Tutorials page.) However, the studies performed did not include new coastal engineering analyses. The studies only included engineering analyses for rivers, streams, and creeks. Any changes in mapped coastal flood zones that may have occurred resulted from FEMA-led project teams using updated topographic data.

The partners listed below have supported, and will continue to support, Region IV with identifying, assessing, and communicating about coastal flood hazards and risks along the Gulf of Mexico and Atlantic Ocean. The type and level of support provided by each partner varies for each study area.

  • Alabama Department of Economic and Community Affairs (ADECA)
  • Florida Division of Emergency Management (FDEM)
  • Georgia Department of Natural Resources (GA DNR), Floodplain Management Office
  • Mississippi Department of Environmental Quality (MDEQ)
  • Mississippi Emergency Management Agency (MEMA)
  • North Carolina Division of Emergency Management (NCEM)
  • North Carolina Floodplain Mapping Program (NCFMP)
  • Northwest Florida Water Management District (NWFWMD)
  • South Carolina Department of Natural Resources (SC DNR)
  • Suwanee River Water Management District (SRWMD)

As indicated in the map below, Region IV provided funding for surge studies in some coastal counties as early as Fiscal Year (FY) 2008 (i.e., the 12-month period beginning on October 1, 2007, and ending on September 30, 2008).  In FY 2013, Region IV contracted for the last two coastal flood risk studies - for the Southwest Florida Study Area and the South Florida Study Area - so program funding has now been dedicated for coastal counties in Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina.

As discussed further on the Coastal Engineering Analysis Overview page, coastal engineering analyses are complex and can take years to complete. For information on when the Preliminary versions of the new digital FIRMs and associated FIS reports will be available for public review, please visit the informational pages for Information for Aabama, Information for Florida, Information for Georgia, Information for North Carolina, and Information for South Carolina pages. (Links to the State-dedicated pages also are provided at the top of each page of this site.) 

On the Information for Florida page, you will find links to the informational pages dedicated to the studies for the Northwest Florida (2008 Study) Study Area, Northwest Florida (2009 Study) Study Area, Big Bend Florida Study Area, West Florida Study Area, Southwest Florida Study Area, South Florida Study Area, East Coast Central Florida Study Area, and Northeast Florida Study Area.
