Notice
Summary
FEMA is asking for your thoughts on new flood risk maps that could change flood zones and water levels in certain communities. These updates might affect flood insurance rules and costs, so it’s important for local folks and property owners to pay attention. You’ve got a chance to comment before the changes become official, so don’t miss out!
Analyzed Economic Effects
2 provisions identified: 0 benefits, 0 costs, 2 mixed.
Flood Map Changes Could Alter Insurance
You may see proposed changes to Base Flood Elevation (BFE), base flood depth, Special Flood Hazard Area (SFHA) boundaries or zone designations, or regulatory floodways on the Flood Insurance Rate Maps (FIRMs) and in supporting Flood Insurance Study (FIS) reports. If your property is in one of the listed communities, those map changes could change whether you must buy flood insurance or change how much your flood insurance costs.
Communities Must Adopt Flood Rules to Keep NFIP
The Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report are the basis of the floodplain management measures that a community is required to adopt or show it already has in effect to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP). If your community does not adopt or maintain those measures, your community’s participation in the NFIP could be at risk, which affects availability of NFIP insurance and related protections for local property owners.
