Greene County, AR: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Greene County scores at the 63.2th 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 1.4 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 2,236 homes FEMA counts inside Greene County's mapped flood zone, 300 carry the flood policy federal law requires there — 13.4% compliance, short of full coverage. Looking beyond the mandated zone, 1.8% of all residential structures in Greene County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
