Bradley County, TN: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Bradley County scores at the 69.1th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Bradley County
Out of 445 homes FEMA counts inside Bradley County's mapped flood zone, 165 carry the flood policy federal law requires there — 37.1% compliance, short of full coverage. Looking beyond the mandated zone, 0.6% of all residential structures in Bradley County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
