The Federal Emergency Management Agency (FEMA) has issued a notice about changes in flood hazard determinations for various communities. These changes include updates to the Base Flood Elevations, Special Flood Hazard Area boundaries, and Flood Insurance Rate Maps based on new scientific or technical data. Communities affected by these updates have 90 days to request a reconsideration of the changes. Revised maps and flood hazard information are available online through the FEMA Map Service Center.
Simple Explanation
FEMA is changing the maps that show where floods might happen in different places. If people don't agree with these changes, they have 90 days to ask for another look.
