How much flood risk does Catoosa County actually carry?
Catoosa County lands at the 65th 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 once every 2 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
Out of 862 homes FEMA counts inside Catoosa County's mapped flood zone, 192 carry the flood policy federal law requires there — 22.3% compliance, short of full coverage. Across all residential structures in Catoosa County, not just the ones FEMA mandates, 0.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
