Arthur County, NE: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Arthur County scores at the 0.5th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 14 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Arthur County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Arthur County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0% of all residential structures in Arthur County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
