Canadian County, OK flood risk explained
Flood hazard in Canadian County sits at the 75.7th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.4 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
11.5% of the homes FEMA requires to carry flood insurance in Canadian County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 116 policies against 1,011 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 Canadian County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Canadian County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Canadian County ranks 798 — 1 being the highest hazard nationally — and 382 by population among all 3144 counties covered here, where 1 is the largest.
