Shawnee County, KS: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Shawnee County scores at the 90th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. 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 2.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Shawnee County
Out of 2,370 homes FEMA counts inside Shawnee County's mapped flood zone, 569 carry the flood policy federal law requires there — 24% compliance, short of full coverage.
