This page provides useful information for technical partners, engineers, surveyors, and contractors who are participating in, or interested in learning more about, FEMA's ongoing coastal analysis and mapping effort.
What You Should Know and Why
As part of the Risk Mapping, Assessment and Planning (Risk MAP) effort, FEMA has undertaken a scientific and engineering effort to update Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports in populated coastal areas nationwide. This FEMA-led effort is being conducted in cooperation with other federal agencies, state agencies, regional entities, non-profit organizations (including universities and professional associations), local communities, and tribal entities. You may be eligible to assist with this effort as a Cooperating Technical Partner.
Coastal Flood Hazard Mapping Technical Resources:
Information on how to submit a Letter of Map Change on behalf of clients.
A number of NFIP Technical Bulletins provide technical recommendations for flood-resistant design techniques based on FEMA Mitigation Assessment Team and partner research
Building code-related information concerning the flood resistant provisions of the 2015, 2012, and 2009 International Codes® (I-Codes), the referenced standard American Society of Civil Engineers (ASCE) 24, Flood Resistant Design and Construction, and the National Flood Insurance Program (NFIP) requirements
FEMA Mitigation Assessment Team (MAT) Reports include technical and engineering design recommendations for structures based on findings following a number of natural disasters. Click here to access the FEMA MAT Reports
Steps You Can Take
Advise communities to build outside of the high-risk SFHAs and/or build to flood-resistant standards.
Understand the coastal flood risk study process so you can correctly advise communities and ensure a smooth process.
Access a community's preliminary flood hazard data by going to FEMA's Preliminary Flood Hazard Data page.
Adhere to NFIP and accepted industry building codes for hurricane and flood-resistant design.
Learn how you can reduce flood risk and increase the community’s disaster resilience by reviewing case studies on how others have built or rebuilt smarter, safer, and stronger in the Best Practices and Case Studies Portfolio.
