Published by Federal Emergency Management Agency | District of Columbia | Catalog Last Checked: May 05, 2026 at 10:35 PM | Dataset Last Updated: September 22, 2023 at 12:00 AM
Location and attributes for FIRM hardcopy map panels. The spatial entities representing FIRM panels are polygons. The polygon for the FIRM panel corresponds to the panel neatlines. FIRM panels must not overlap or have gaps within a study. In situations where a portion of a panel lies outside the jurisdiction being mapped, the user must refer to the S_Pol_Ar table to determine the portion of the panel area where the FIRM Database shows the effective flood hazard data for the mapped jurisdiction.
