How much flood risk does Christian County actually carry?
Christian County lands at the 41.5th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.6 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 87 homes FEMA counts inside Christian County's mapped flood zone, 10 carry the flood policy federal law requires there — 11.5% compliance, short of full coverage. Across all residential structures in Christian County, not just the ones FEMA mandates, 0.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
