How much flood risk does Carroll County actually carry?
Carroll County lands at the 65.1th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.1 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Out of 125 homes FEMA counts inside Carroll County's mapped flood zone, 1 carry the flood policy federal law requires there — 0.8% compliance, short of full coverage. Across all residential structures in Carroll County, not just the ones FEMA mandates, 0% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
