Is Republic County, KS in a flood zone?
FEMA's National Risk Index puts Republic County's flood hazard at the 14.5th 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 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
