How much flood risk does Park County actually carry?
Park County lands at the 60.8th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — 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. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Park County's flood-insurance compliance gap
2.6% of the homes FEMA requires to carry flood insurance in Park County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 11 policies against 425 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Park County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Park County against the rest of the country
