Floodplain Management

The Federal Emergency Management Agency (FEMA) has been updating the Flood Insurance Rate Maps (FIRMS) for Montgomery County.  These are the maps that depict the floodway, floodplain, and various flood zones for the County’s streams.  Once these maps are finalized, the municipalities will be required to update their floodplain ordinance to maintain their standing in the National Flood Insurance Program (NFIP).
