Holt County, MO: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Holt County scores at the 21.7th 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 1 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Holt County
FEMA hasn't published a residential structure count for Holt 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, 5.2% of all residential structures in Holt County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Holt County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Holt County ranks 2506 — 1 being the highest hazard nationally — and 2869 by population among all 3144 counties covered here, where 1 is the largest. Holt County, Missouri covers 462.696 square miles and counts roughly 4,241 residents.
