The Department of Homeland Security's Federal Emergency Management Agency (FEMA) has finalized new or modified flood hazard determinations for various communities. These changes involve adjustments to flood elevations, flood insurance rate maps, and floodway designations. Affected communities must adopt updated flood management measures to remain part of the National Flood Insurance Program. This information is available for review both locally and online through FEMA's Map Service Center.
Simple Explanation
The United States government is telling certain towns that they need to look at new maps showing where it might flood. These maps help them plan better and keep everyone safe from floods.
