Preliminary Flood Insurance Rate Maps

FEMA Preliminary Flood Maps Issued:

Open House Scheduled for April 2.

The FEMA preliminary maps show 200 structures will be placed within the new regulated 100 year floodplain. The 100 year floodplain is generally the highest risk area.

If your business, or residence is in the Special Flood Hazard Area, please attend our FEMA Preliminary Flood Map Open House on April 2, 2019. The open house will occur between 4PM-7PM at the Department of Planning located at 417 E. Fayette Street, 8th floor, Baltimore, MD 21202. Email [email protected] for more details, floodplain development guidelines, or Map Information Services.
