Harvey County, KS flood risk explained
Flood hazard in Harvey County sits at the 38.9th 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 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.
Harvey County's flood-insurance compliance gap
Out of 817 homes FEMA counts inside Harvey County's mapped flood zone, 114 carry the flood policy federal law requires there — 14% compliance, short of full coverage. Looking beyond the mandated zone, 1% of all residential structures in Harvey County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
