Analyzed Economic Effects
4 provisions identified: 2 benefits, 0 costs, 2 mixed.
Updated flood maps affect insurance
FEMA revised flood maps (FIRMs/FIS reports) for the listed communities on the dates shown in the table below (for example, Jul. 7, 2025; Jun. 25, 2025; May 16, 2025). You and your insurer must use the current effective community number and the revised maps for all new flood insurance policies and renewals.
Maps set community NFIP requirements
The revised FIRM and FIS reports are the basis for the floodplain management measures that each community must adopt or show they have in effect to qualify or remain qualified for the National Flood Insurance Program (NFIP). These measures are the minimum required under 44 CFR 60.3, though communities may keep stricter local rules.
90-day window to request reconsideration
From the date of the second local newspaper notice, you have 90 days to ask your community to request that FEMA reconsider the flood hazard changes. To file a request, submit it through the Chief Executive Officer of the community listed in the table.
Where to inspect revised map info
Revised flood hazard information for each listed community is available for inspection online at the FEMA Map Service Center (https://msc.fema.gov) and at the local community map repository address shown in the table. You can compare the revised FIRM/FIS to the current effective versions using those resources.
