Logan County, OK: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Logan County scores at the 50.7th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. 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 2 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
3.8% of the homes FEMA requires to carry flood insurance in Logan County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 16 policies against 426 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.2% of all residential structures in Logan County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
