Miami County, KS flood risk explained
Flood hazard in Miami County sits at the 46.9th national percentile, below the national norm for flood 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. 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 124 homes FEMA counts inside Miami County's mapped flood zone, 24 carry the flood policy federal law requires there — 19.4% compliance, short of full coverage. Looking beyond the mandated zone, 0.3% of all residential structures in Miami County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
