Is Blount County, TN in a flood zone?
FEMA's National Risk Index puts Blount County's flood hazard at the 74th percentile nationally — a middling flood hazard by national standards — 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. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Out of 679 homes FEMA counts inside Blount County's mapped flood zone, 156 carry the flood policy federal law requires there — 23% compliance, short of full coverage. Across all residential structures in Blount County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
