Finalized flood map changes for listed communities
FEMA finalized new flood hazard determinations (changes to Base Flood Elevations, Special Flood Hazard Area boundaries, and floodways) for communities listed in the notice. The LOMRs were finalized on the dates shown in the table (for example, Sep. 12, 2025; Sep. 9, 2025; Sep. 22, 2025). If you live in the affected communities in AZ, CA, CO, ID, NV, NC, or UT, your flood zone, insurance requirements, and building rules might change.
Communities must meet NFIP floodplain rules
The new or modified flood hazard information is the basis for floodplain management measures that each listed community is required either to adopt or to show are already in effect in order to remain qualified for participation in the National Flood Insurance Program (NFIP). Communities must follow the floodplain management criteria required by 44 CFR 60.3.
Maps and LOMRs are available; use current community number
Each Letter of Map Revision (LOMR) revises the Flood Insurance Rate Maps (FIRMs) and sometimes the Flood Insurance Study (FIS) reports; the final LOMRs and maps are available at the Community Map Repository listed in the table and online through the FEMA Map Service Center (https://msc.fema.gov). The notice says the current effective community number shown must be used for all new policies and renewals.
