Is Broadwater County, MT in a flood zone?
FEMA's National Risk Index puts Broadwater County's flood hazard at the 19.1th 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 6 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Broadwater County's flood-insurance compliance gap
Out of 81 homes FEMA counts inside Broadwater County's mapped flood zone, 2 carry the flood policy federal law requires there — 2.5% compliance, short of full coverage. Across all residential structures in Broadwater 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.
