Summary
FEMA is updating flood risk maps for certain communities based on new science and data. These changes affect flood zones, flood heights, and insurance rules, so homeowners and businesses in those areas should check the new maps. You’ve got 90 days after local notice to ask for a review, and these updates could impact flood insurance costs and requirements starting on the listed dates.

3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Flood map changes may alter insurance
FEMA revised Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports for specific communities; these changes affect flood zones, base flood elevations, and insurance rules and could change flood insurance costs and requirements starting on the dates listed in the table (examples include Dec. 26, 2025; Dec. 31, 2025; Jan. 2, 2026; Jan. 16, 2026). The current effective community number shown in the table must be used for all new policies and renewals.
90‑day review period to challenge maps
After the second local newspaper notice, any person has 90 days to request that the Assistant Administrator for the Federal Insurance Directorate reconsider the flood hazard determinations; requests must be submitted through the community to the Chief Executive Officer listed in the table. The flood hazard determination information may change during that 90‑day period.
Revised maps available online and locally
Revised flood hazard information and the current effective FIRM and FIS reports for each listed community are available online at the FEMA Map Service Center (https://msc.fema.gov) and at the community map repository addresses shown in the table; use those resources to compare old and revised maps before filing for insurance or appeals.
