The Federal Emergency Management Agency (FEMA) has issued updates to the flood hazard determinations for various communities. These updates, shown in Letters of Map Revision (LOMRs), change aspects such as flood elevations, special flood hazard zones, and regulatory floodways. These changes affect the Flood Insurance Rate Maps and may impact requirements for floodplain management within the National Flood Insurance Program. Communities must implement these updates to continue participating in the program, although they have the option to adopt stricter measures if desired.
Simple Explanation
FEMA has updated flood maps for some places to show how likely it is for certain areas to flood. These updates help people know where it's risky to build or live because of flooding.
