The Federal Emergency Management Agency (FEMA) announced new or modified flood hazard determinations for various communities. These determinations include changes to flood risk areas as shown by Letters of Map Revision (LOMR), impacting Flood Insurance Rate Maps (FIRMs). Such changes will influence flood insurance premium calculations for new structures and their contents. Communities must adapt their floodplain management practices to comply with these updated determinations to continue participating in the National Flood Insurance Program (NFIP).
Simple Explanation
FEMA is telling some places how deep water might get when it rains a lot, so people know where it's safe to build homes. These changes help decide how much people need to pay to protect their new houses from floods.
