Lamoille County, VT flood risk explained
Flood hazard in Lamoille County sits at the 42.8th national percentile, below the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.6 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
FEMA hasn't published a residential structure count for Lamoille 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, 1.1% of all residential structures in Lamoille County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Lamoille County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Lamoille County ranks 1860 — 1 being the highest hazard nationally — and 1567 by population among all 3144 counties covered here, where 1 is the largest. Lamoille County, Vermont covers 461.255 square miles and counts roughly 26,248 residents.

Where Lamoille County's figures come from
