Analyzed Economic Effects
5 provisions identified: 2 benefits, 1 costs, 2 mixed.
Updated flood maps may change insurance
FEMA revised Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) information for many communities by changing Base Flood Elevations, flood depths, Special Flood Hazard Area boundaries or zone designations, and regulatory floodways. If you live in one of the listed communities in the table, your flood insurance requirements or costs could change when these map revisions take effect on the dates shown (dated May 13, 2026 through June 12, 2026).
You have 90 days to appeal map changes
From the date of the second publication of notification in a newspaper of local circulation, any person has 90 days to ask the local community to request that FEMA reconsider the revised flood hazard determinations. If you live or own property in a listed community, watch for the local notice and submit any request within that 90-day window.
Communities must meet NFIP minimum requirements
FEMA states that the revised FIRMs and FIS reports are the basis of the floodplain management measures communities are required to adopt or demonstrate they already have in effect to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP). Communities may also adopt stricter local requirements if they choose.
Revised flood maps posted online and locally
Revised flood hazard information for each listed community is available online through the FEMA Map Service Center (https://msc.fema.gov) and at the local community map repository addresses shown in the table. You can inspect the revised maps and compare them to current FIRMs and FIS reports using those resources.
New community number used for policies
The notice says the current effective community number shown in the table must be used for all new flood insurance policies and renewals for the listed communities. That means insurers and policyholders should use the updated community number when issuing new policies or renewing existing policies after the map change date.
