How much flood risk does Burleigh County actually carry?
Burleigh County lands at the 77.4th 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 1 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.
Who actually carries the flood insurance FEMA requires
Out of 980 homes FEMA counts inside Burleigh County's mapped flood zone, 407 carry the flood policy federal law requires there — 41.5% compliance, short of full coverage. Across all residential structures in Burleigh County, not just the ones FEMA mandates, 1.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
