How much flood risk does Sheridan County actually carry?
Sheridan County lands at the 2.2th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard 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.
