In support of the NFIP, FEMA has issued Flood Insurance Rate Maps (FIRM) for most NFIP participating communities in New Hampshire. FIRMs identify areas with a one percent annual chance flood hazard in a community. These areas are called Special Flood Hazard Areas (SFHA). The one percent annual chance flood is also referred to as the base flood or 100-year flood. The flood hazards areas shown on FIRMs are based on the best information available at the time the maps were prepared.
