Sibley County, MN flood risk explained
Flood hazard in Sibley County sits at the 31.2th national percentile, among the lowest flood hazard in the country; 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. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Sibley County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Sibley 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% of all residential structures in Sibley County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Among the 3144 US counties FEMA scores for flood hazard, Sibley County ranks 2222 — 1 being the highest hazard nationally — and 2081 by population among all 3144 counties covered here, where 1 is the largest. Sibley County, Minnesota is home to about 15,194 people across 588.967 square miles of land.
What to do next if you own or are buying in Sibley County
