The Federal Emergency Management Agency (FEMA), part of the Department of Homeland Security, has updated flood hazard determinations for various communities. These changes are based on new scientific or technical data and are shown on the Flood Insurance Rate Maps (FIRMs) and in Flood Insurance Study (FIS) reports. The updates are documented through a Letter of Map Revision (LOMR), which insurance agents use to calculate flood insurance rates for new buildings. Community members have 90 days to request reconsideration of these changes, and the details are available online or at local community map repositories.
Simple Explanation
FEMA has updated maps that help people know which areas might get flooded, and these new maps will be used to figure out how much money people need to pay for flood insurance. If anyone thinks the changes are wrong, they have 90 days to ask for another look.
