Updated Flood Maps Take Effect Sept 19, 2025
On September 19, 2025, updated Flood Insurance Rate Maps (FIRMs) and supporting Flood Insurance Study (FIS) reports become final for the listed communities. The updates may include changes to Base Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, or regulatory floodways, and the notice says these changes affect homeowners, renters, and local governments by changing flood insurance rules and safety measures.
Communities Must Use New Maps For NFIP Qualification
The final FIRMs and FIS reports are the basis of the floodplain management measures that a community is required to adopt or to show evidence of having an effect in order to qualify or remain qualified for participation in FEMA's National Flood Insurance Program (NFIP). Communities listed in the notice (for example: Mendocino County, CA; Greene County, MO; multiple counties and towns in NC; Golden Valley County, ND; Charlotte County, VA; Hardin County, IL) must follow those measures tied to the new maps.
