Description: A line feature class of Federal Emergency Management Agency (FEMA) base flood elevation cross sections within Arlington County. The data depicts the base flood elevation at cross sections along major streams. This is the elevation of surface water resulting from a flood that has a 1% chance of equaling or exceeding that level in any given year.Contact: Department of Environmental ServicesData Accessibility: Publicly AvailableUpdate Frequency: As NeededLast Revision Date: 11/14/2023Creation Date: 11/14/2023Feature Dataset Name: FEMALayer Name: FEMA_Base_Flood_Elevation_arc
