Is Comanche County, KS in a flood zone?
FEMA's National Risk Index puts Comanche County's flood hazard at the 2.8th percentile nationally — among the lowest flood hazard in the country — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 3 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Comanche County
