Finalized flood map changes

FEMA finalized new or modified flood hazard determinations (Base Flood Elevations, Special Flood Hazard Area boundaries, zone designations, and/or regulatory floodways) as shown in Letters of Map Revision for the listed communities. The LOMRs revise Flood Insurance Rate Maps and, in some cases, Flood Insurance Study reports, with finalization dates shown in the table (examples include May 6, 2026; May 14, 2026; May 19, 2026; May 21, 2026; May 22, 2026; May 28, 2026; May 29, 2026; June 1, 2026; June 4, 2026; and June 5, 2026).

Maps set NFIP management rules

The new or modified flood hazard information becomes the basis for the floodplain management measures a community must adopt or show are already in effect for it to remain qualified for participation in the National Flood Insurance Program (NFIP). Communities listed must use these revised flood hazard determinations when meeting NFIP requirements.

Use updated community number for policies

The notice states the current effective community number shown in the LOMR must be used for all new flood insurance policies and renewals. Insurers and policyholders in the listed communities should use the updated community number when obtaining or renewing NFIP coverage.

Owners urged to review final maps

FEMA encourages lessees and owners of real property in the listed communities to review the final flood hazard information at the community map repository or online through the FEMA Map Service Center (https://msc.fema.gov). The notice identifies community map repository addresses and states each LOMR is available for inspection.
