Green County, KY: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Green County scores at the 22.4th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. 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 once every 2 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Green County's flood-insurance compliance gap
Out of 69 homes FEMA counts inside Green County's mapped flood zone, 5 carry the flood policy federal law requires there — 7.3% compliance, short of full coverage. Looking beyond the mandated zone, 0.1% of all residential structures in Green County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Green County ranks
Among the 3144 US counties FEMA scores for flood hazard, Green County ranks 2480 — 1 being the highest hazard nationally — and 2313 by population among all 3144 counties covered here, where 1 is the largest. Green County, Kentucky covers 285.963 square miles and counts roughly 11,552 residents.
