Preliminary Flood Insurance Rate Map

As 1 of nearly 20,000 communities across the country, Prince George's County participates in the National Flood Insurance Program (NFIP). A major component of this program is Flood Hazard Mapping. The Federal Emergency Management Agency (FEMA) issues and maintains Flood Insurance Rate Maps (FIRM), which are official maps showing flood hazard areas in communities. These maps are utilized as the basis for local floodplain management regulations and mitigation efforts, to assess flood risk, and to determine if flood insurance is required for structure(s) on a property. Portions of the FIRM for Prince George’s County have been effective since June 18, 1987.

Flood Insurance Study

On March 16, 2016, FEMA issued the Letter of Final Determination (LFD) for Prince George’s County and Incorporated Areas.  The revised Flood Insurance Rate Maps (FIRMs) and associated Flood Insurance Study (FIS) will become effective on September 16, 2016.  The revised FIS and FIRM reflect proposed updates to the information shown on the effective FIRM for Prince George's County and incorporated areas. Updated map features include, but are not limited to: 1-percent-annual-chance (formerly 100-year) flood elevations; floodplain and floodway boundaries; flood zone designations; street names and locations; bridge and culvert locations and stream names. Note that coastal flood hazard zones for the Patuxent River have been added to the DFIRM. The preliminary FIRM has been prepared in a digital and countywide format (e.g. the City of Laurel, Maryland has been incorporated in the FIRM). The new FIRM is commonly referred to as a countywide Digital Flood Insurance Rate Map (DFIRM).

For your convenience, the preliminary DFIRM and FIS are available for viewing online.



Please forward any comments or concerns about the preliminary DFIRM and FIS report to Dawn Hawkins-Nixon, Team Manager, Department of Environmental Resources, Prince George’s County, at 301-883-5839. Comments on technical issues and non-technical information (such as corporate limits, road names, bridges and stream names) are welcome.
