Logan County, ND: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Logan County scores at the 5.9th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 5 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
FEMA hasn't published a residential structure count for Logan County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.1% of all residential structures in Logan County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Logan County ranks
Among the 3144 US counties FEMA scores for flood hazard, Logan County ranks 2968 — 1 being the highest hazard nationally — and 3048 by population among all 3144 counties covered here, where 1 is the largest. Logan County, North Dakota covers 992.599 square miles and counts roughly 1,880 residents.
What to do next if you own or are buying in Logan County
