NFIP Policy Index
The process of the gradual wearing away of land masses. Erosion can occur along coasts and rivers and streams. Although flood-related erosion is covered by flood insurance, this peril is not covered per se under the NFIP. The mapping and regulatory standards of the NFIP do not currently address erosion, but Community Rating System (CRS) credit is given to communities that include this hazard in their regulations, planning, public information, hazard disclosure, and flood warning programs. Many States and communities have established setbacks and other requirements in areas subject to erosion.

In flood-prone coastal areas subject to long-term erosion, flood hazard zones shown on Flood Insurance Rate Maps (FIRMs) may not accurately reflect current flood hazards due to the dynamic nature of the nearshore environment. As erosion occurs, flood hazards typically migrate inland. Base Flood Elevations (BFEs) may increase and additional areas may become subject to wave action.
