FEMA Proposes New Flood Maps; Communities Urged to Comment Now
Published Date: 3/21/2025
Notice
Summary
FEMA is asking communities to review and comment on proposed changes to flood risk maps that show where floods might happen and how deep they could be. These updates could affect local rules and flood insurance costs, so it’s important for residents and officials to weigh in soon. The changes help keep communities safe and eligible for the National Flood Insurance Program.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 1 costs, 2 mixed.
Communities must adopt measures to keep NFIP eligibility
The preliminary FIRM and FIS reports are the basis for the floodplain management measures that a community must adopt or show it has in effect to qualify or remain qualified for the National Flood Insurance Program (NFIP). If a community does not adopt required measures based on the updated maps, its eligibility for the NFIP could be affected.
Flood-map changes may alter insurance costs
FEMA is proposing changes to Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports that may add or change Base Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, or regulatory floodways. These map changes could affect local rules and your flood insurance costs, so residents and officials are asked to review and comment.
Local building and land-use rules may change
Because FIRMs and FIS reports form the basis for floodplain management, the proposed updates can lead communities to change local building, land-use, or floodplain requirements. Those changes can affect new construction, renovations, and permitting in the affected areas.
