Is Beaver County, PA in a flood zone?
FEMA's National Risk Index puts Beaver County's flood hazard at the 87th percentile nationally — a middling flood hazard by national standards — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.7 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Beaver County's flood-insurance compliance gap
Out of 802 homes FEMA counts inside Beaver County's mapped flood zone, 157 carry the flood policy federal law requires there — 19.6% compliance, short of full coverage. Across all residential structures in Beaver County, not just the ones FEMA mandates, 0.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
