The Federal Emergency Management Agency (FEMA) produces Flood Insurance Rate Maps (FIRMs) which identify areas that are at risk of flooding. FIRMs include statistical information such as data for river flow, storm tides, hydrologic/hydraulic analyses, and rainfall and topographic surveys. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). In Baltimore City, the regulated floodplain includes the 1% and 0.2% annual-chance flood areas, also known as the 100-year and 500-year floodplain.

The City of Baltimore Floodplain Management Office provides information about Baltimore City’s FIRMs such as assistance with determining if a property is located in the Special Flood Hazard Area, what the estimate Base Flood Elevation (BFE) is for a property, and what flood depths may be at that site. Baltimore City Floodplain Managers will also provide information about historic flooding, V-zones, the floodway, and natural floodplain functions in a specific area.
