Deschutes County, OR: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Deschutes County scores at the 88.9th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. 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. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Deschutes County
Homes with a federally backed mortgage inside Deschutes 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, 21.2% of them do — 57 active policies against 269 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.2% of all residential structures in Deschutes County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
