The Federal Emergency Management Agency (FEMA) has issued a notice regarding changes in flood hazard determinations for certain communities, based on updated scientific or technical information. These changes affect Base Flood Elevations, Special Flood Hazard Area boundaries, and other related factors, and are reflected in updated Flood Insurance Rate Maps and Flood Insurance Study reports. Community members have 90 days to appeal these determinations following notification. The changes are made under federal regulations and aim to aid in floodplain management and the National Flood Insurance Program.
Simple Explanation
FEMA is telling some towns that their maps showing where big floods might happen are being updated because they have new information. People in those towns can say if they think any changes aren't right, but they need to do it quickly.
