Is Comanche County, OK in a flood zone?
FEMA's National Risk Index puts Comanche County's flood hazard at the 83.6th percentile nationally — 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 2 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
Homes with a federally backed mortgage inside Comanche County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 20.1% of them do — 264 active policies against 1,311 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Comanche County, not just the ones FEMA mandates, 1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
