Notice
Summary
FEMA just updated flood risk maps for several communities, changing flood zones and water levels that affect flood insurance rules. If you live or own property in these areas, your insurance rates or building rules might change soon. These updates are final and already in effect, so check your local map or online to see how you’re impacted and plan ahead!
Analyzed Economic Effects
3 provisions identified: 0 benefits, 1 costs, 2 mixed.
Final Flood Map Changes
If you own or lease property in any of the listed communities in the notice (examples of states: AL, AZ, CA, CO, FL, IL, ID, LA, NV, NC, TX, WI), FEMA finalized new flood maps (Letters of Map Revision) on the dates shown in the table. These LOMRs change Base Flood Elevations, Special Flood Hazard Area boundaries, zone designations, or regulatory floodways and may change your flood insurance rates or local building requirements. Review your local community map repository or the FEMA Map Service Center to see the exact finalized date and changes for your property (examples of finalized dates in the table include Aug 8, 2025; Aug 13, 2025; Sep 18, 2025; Oct 8, 2025).
Community Floodplain Rules Required
FEMA says the new or changed flood hazard information is the basis for floodplain management measures that each affected community must adopt or show are already in effect so the community can remain qualified for participation in the National Flood Insurance Program (NFIP). That requirement applies to the communities listed in the table of the notice.
Use New Community Number For Policies
The notice says the current effective community number shown in the LOMR must be used for all new flood insurance policies and renewals in the affected communities. That means when you buy or renew NFIP coverage for a property in a listed community, insurers and agents must use the updated community number from the finalized LOMR.
