How much flood risk does Yazoo County actually carry?
Yazoo County lands at the 48.5th 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.
Yazoo County's flood-insurance compliance gap
Out of 1,293 homes FEMA counts inside Yazoo County's mapped flood zone, 233 carry the flood policy federal law requires there — 18% compliance, short of full coverage. Across all residential structures in Yazoo County, not just the ones FEMA mandates, 2.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
