This pages details FEMA's efforts to complete coastal flood studies along the Atlantic coast and provides links to resources for the public to obtain information on the status of specific coastal studies.
The Atlantic coastline encompasses 14 States for a combined total of approximately 28,673 miles of tidal shoreline. For the past decade, FEMA has been updating Flood Insurance Studies and Flood Insurance Rate Maps (FIRMs) for the entire populated coastline of the country to provide improved flood hazard information to coastal communities. Many communities along the Atlantic seaboard have already received updated flood maps in the form of preliminary or effective FIRMs.
Flooding along the Atlantic coast is a product of combined offshore, near-shore and shoreline processes. The inter-relationships of these processes are complex and their relative effects vary based on different coastal settings. To address these complexities and provide guidelines for those performing the coastal engineering analysis FEMA has issued coastal flood risk study guidelines. These guidelines offer insight and recommended methods to analyze complex coastal processes in a technically reasonable and consistent way, while improving community resilience to flood losses (life, property and business).
For the New England coastline, FEMA published Updated Tidal Profiles for the New England Coastline (March, 2012), an update to the 1988 U.S. Army Corps of Engineers coastal flood frequency curves presented in Tidal Flood Profiles, New England Coastline. The intent of FEMA’s 2012 report is to provide an inclusive source of coastal stillwater elevations for all of New England, to be used in analysis supporting FEMA Flood Insurance Studies.
Four FEMA Regions share jurisdiction of the Atlantic coast, working in partnership with each other and with local, tribal, state and other federal agencies to ensure the coastal flood studies are carried out effectively and efficiently.
