Bureau County, IL flood risk explained
Flood hazard in Bureau County sits at the 63.4th 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 once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Bureau County's flood-insurance compliance gap
24.1% of the homes FEMA requires to carry flood insurance in Bureau County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 45 policies against 187 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.4% of all residential structures in Bureau County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Bureau County ranks
Among the 3144 US counties FEMA scores for flood hazard, Bureau County ranks 1204 — 1 being the highest hazard nationally — and 1383 by population among all 3144 counties covered here, where 1 is the largest. About 32,486 people live in Bureau County, Illinois, spread over 869.071 square miles.
