Notice
Summary
The government has updated flood risk maps for certain communities, changing flood levels and boundaries to keep everyone safer. If you live or own property in these areas, these changes could affect your flood insurance and building rules. These updates are final and communities need to act soon to stay in the flood insurance program and avoid extra costs.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 1 costs, 1 mixed.
Finalized Flood Map Changes
If you live in or own property in the communities listed, FEMA has finalized changes to flood maps that update Base Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, and regulatory floodways on Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports. These map changes could affect your flood insurance requirements and local building rules.
Community NFIP Adoption Requirement
The Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report form the basis of floodplain management measures that a community is required to adopt or to show evidence of having adopted in order to qualify or remain qualified for participation in FEMA's National Flood Insurance Program (NFIP). If a listed community does not adopt or demonstrate the required measures based on the new maps, its participation in the NFIP (and related local flood insurance availability and building rule alignment) may be affected.
