Coastal Flood Hazard Technical Resources

Main Content

This page is a resource for all coastal flood hazard information pertinent to FEMA and the National Flood Insurance Program (NFIP), including technical modeling and mapping applications, such as FEMA Guidelines and Standards; FEMA accepted coastal models and the Coastal Hazard Analysis Modeling Program (CHAMP). This page is intended for mapping professionals and contractors and mitigation and urban planners near coastal areas.

As the agency responsible for administration of the NFIP, FEMA's Federal Insurance and Mitigation Administration (FIMA) conducts hydrologic and hydraulic analyses to identify coastal flood hazards in communities throughout the United States. Stakeholders are encouraged to visit this page regularly for updates on coastal flood hazard mapping activites. 

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.

Hurricane Information

  • FEMA Hazards - Hurricane Homepage provides recommended actions to be taken before, during and after a hurricane and hurricane preparedness training courses and other resources including FEMA publications on how to plan and prepare for a hurrincane. Additional informative topics include:
    • Hurricane Basic Facts
    • Saffir/Simpson Scale
    • Hurricane Background and Preparedness Information
    • Hurricane Glossary of Terms
    • Top Ten Hurricane Disasters Ranked by FEMA Relief
  • FEMA's National Hurricane Program helps protect communities and residents from hurricane hazards through various projects and activities. Established in 1985, the NHP also conducts assessments and provides tools and technical assistance to state and local agencies in developing hurricane evacuation plans.
  • Mitigation Assessment Team (MAT) Program is an updated and enhanced version of FEMA's previous Building Performance Assessment Team (BPAT) Program. Drawing on the combined resources of a federal, state, local and private sector partnership, the MAT Program allows FEMA to assemble and quickly deploy teams of investigators. These investigators evaluate the performance of buildings and related infrastructure in response to the effects of natural and man-made hazards.
