This page provides useful information for technical partners, engineers, surveyors and contractors who are participating in, or interested in learning more about the 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 Studies (FISs) 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 Hazard Analysis Modeling Program (CHAMP) including technical information and download instructions, as well as an email sign-up for news.
Other Coastal Flood Hazard Mapping Technical Resources:
Information on how to submit a Letter of Map Change on behalf of clients.
When building along the coast, refer to the Coastal Construction Manual: Principles and Practices of Planning, Siting, Designing, Constructing and Maintaining Residential Buildings in Coastal Areas (4th ed.).
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 is found in:
I-Codes Sample Checklists for Flood Hazards. This document contains a Plan Review Checklist for Flood Hazard Area Application Review and an Inspection Checklist for Flood Hazard Area Inspections in both A Zones and V Zones. The checklists are from Reducing Flood Losses Through the International Code Series (3rd Edition).
Quick Reference Guide: Comparison of Select NFIP & Building Code Requirements for Special Flood Hazard Areas. This guide illustrates the similarities and highlights the differences between the National Flood Insurance Program (NFIP) minimum requirements and the requirements of the International Code Series (I-Codes) and Flood Resistant Design and Construction (ASCE 24) for most residential and commercial buildings
CodeMaster for Flood Resistant Design (2011). Provides designers with an easy-to-use desk reference that identifies the flood provisions in the 2009 and 2012 International Building Code® (IBC®) and International Residential Code® (IRC®), as well as the flood requirements of American Society of Civil Engineers (ASCE) standards 7-05, 7-10 and 24-05. The eight-page guide provides sections on preliminary considerations and design process, key flood terminology, a 12-step process to incorporate flood resistance in the design of a building, an example showing the 12-step process being executed and information on additional FEMA mitigation resources related to flood-resistant design. This guide can be purchased from the International Code Council.
FEMA Mitigation Assessment Team (MAT) Reports include technical and engineering design recommendations for structures based on findings from a number of natural disasters. Click here to read the FEMA MAT Reports.
Steps You Can Take
Advise communities to build outside of the high-risk SFHAs and/or by building to flood-resistant standards.
Understand the coastal flood risk study process so you can correctly advise communities and ensure a smooth process.
Know the Letter of Map Change process, so that you can assist communities and citizens when questions arise.
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.
