FEMA Quietly Redraws Flood Lines for Dozens of Towns
Published Date: 6/11/2026
Notice
Summary
FEMA is updating flood risk maps for certain communities using new science and data. These changes affect flood zones, flood heights, and insurance rules, so residents and businesses might see new flood risks and insurance costs. People have 90 days after local notice to ask for a review before changes become final.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 2 costs, 1 mixed.
Map updates can change your flood risk
FEMA revised Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports for specific communities to update Base Flood Elevations, flood depths, Special Flood Hazard Area boundaries or zone designations, and regulatory floodways. If you live or run a business in one of the listed communities, these map changes may change your flood risk and could change your flood insurance costs when the changes are finalized on the dates shown in the table.
Community NFIP adoption requirement
FEMA states the revised FIRM and FIS reports are the basis of the floodplain management measures a community is required to adopt or to show evidence of having in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP).
90-day window to request reconsideration
From the date of the second local newspaper notice, any person has 90 days to ask the community to request that FEMA reconsider the flood hazard changes before they become final. The flood hazard information may change during that 90-day period.
New community number required for policies
The notice states that the current effective community number shown in the table must be used for all new flood insurance policies and renewals for the listed communities. This affects how insurers identify the community on new policies and renewals once the map revisions are in effect.
