Is there a floodplain on my property?

A 100-year floodplain is the area that has a one percent chance of being flooded in an amount equal to or greater than its average in any given year. The Environmental Planning Section has copies of Federal Emergency Management Agency [FEMA] maps and some individual watershed studies that depict the approximate location of the 100-year floodplain. The official source for floodplain information is the Prince George's County Department of Environmental Resources. (301-883-5777)
