Is Weakley County, TN in a flood zone?
FEMA's National Risk Index puts Weakley County's flood hazard at the 21.9th percentile nationally — among the lowest flood hazard in the country — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Weakley County's flood-insurance compliance gap
Out of 90 homes FEMA counts inside Weakley County's mapped flood zone, 21 carry the flood policy federal law requires there — 23.3% compliance, short of full coverage. Across all residential structures in Weakley County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
