How much flood risk does Shoshone County actually carry?
Shoshone County lands at the 76th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — 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 1 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
5.3% of the homes FEMA requires to carry flood insurance in Shoshone County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 107 policies against 2,006 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Shoshone County, not just the ones FEMA mandates, 1.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
