Counts describe density, not danger by themselves; proximity to a specific address is what matters. Check any address against the official state registry (FDLE in Florida, Maryland DPSCS in Maryland) or the federal NSOPW site.

Interior largely outside the mapped floodplain; hazard follows the rivers and creeks
Live queries against Maryland iMAP's Effective FEMA Floodplain layer found no flood-hazard polygon at multiple interior Arnold test points, while Zone A appeared at the Deep Creek headwaters and 205 mapped floodplain polygons intersect the ZIP's bounding area — concentrated along the Severn and Magothy river shorelines and creek valleys. Waterfront, creek-adjacent, and low lots need an address-level check; the suburban interior generally does not sit in the mapped Special Flood Hazard Area.
