FEMA Maps Flood Risks: Homeowners Brace for Insurance Shifts
Published Date: 12/8/2025
Notice
Summary
FEMA is updating flood risk maps for several communities, which could change flood zones and water levels used for insurance and safety rules. If you live or own property in these areas, these changes might affect your flood insurance costs and building rules. You’ve got until March 9, 2026, to check the new maps and share your thoughts before they become official.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 1 costs, 1 mixed.
Flood map changes may alter costs
FEMA proposes updates to Flood Insurance Rate Maps (FIRMs) that may add or change Base Flood Elevations (BFE), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, or regulatory floodways. If you live or own property in the affected areas (for example, Huron County, Michigan studies with Preliminary FIRM dates November 30, 2023 and July 11, 2025), these map changes might affect your flood insurance costs and local building rules.
Communities must meet NFIP rules
The Preliminary FIRM and FIS reports are the basis of the floodplain management measures communities are required to adopt or show they have in effect under 44 CFR 60.3 to qualify or remain in the National Flood Insurance Program (NFIP). Communities that do not adopt required measures may affect residents' and property owners' ability to participate in the NFIP.
You can inspect maps and comment
Preliminary FIRMs and, where applicable, Flood Insurance Study (FIS) reports are available online at https://hazards.fema.gov/femaportal/prelimdownload and at local Community Map Repository addresses listed in the notice; current effective maps are at https://msc.fema.gov. You may submit comments identified by Docket No. FEMA-B-2575 to FEMA; comments must be submitted on or before March 9, 2026.
Scientific Resolution Panel option for appeals
Communities may use a Scientific Resolution Panel (SRP) to resolve appeals of revised flood hazard information only after FEMA and the local community have engaged in a collaborative consultation process for at least 60 days without a mutually acceptable resolution. SRPs are independent expert panels that review conflicting technical data and provide recommendations.
