Coastal Flood Hazard Technical Resources

Main Content

As the agency responsible for administration of the National Flood Insurance Program (NFIP), the Federal Emergency Management Agency's (FEMA) Federal Insurance and Mitigation Administration (FIMA) conducts hydrologic and hydraulic analyses to identify coastal flood hazards in communities throughout the United States.

The Coastal Flood Hazard Technical Resources Page is a resource for all coastal flood hazard information pertinent to FEMA and the NFIP, including technical modeling and mapping applications such as FEMA Guidelines and Specifications, FEMA accepted coastal models, and the Coastal Hazard Analysis Modeling Program (CHAMP). This site will be updated with additional topics in the near future. Please check back frequently for updates.

Coastal Flood Hazard Guidance Documents and Forms

Coastal Flood Hazard Analysis Data Requirements is a brief introduction to some of the main modeling and mapping theoretical components associated with a FEMA coastal flood hazard analysis. These components should be considered when developing coastal map revision requests in order for the requester to submit a complete request including the provision of MT-2 Forms. More detailed information is provided in the Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix D. Updates to the Atlantic and Gulf and Pacific Coast sections of Appendix D can be found at the links below:

Detailed guidance for coastal flood hazard analyses and mapping in sheltered waters was developed subsequent to the updates and documented in a technical memorandum.
