Lane County, OR flood risk explained
Flood hazard in Lane County sits at the 97.2th national percentile, well above 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. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Lane County's flood-insurance compliance gap
16.1% of the homes FEMA requires to carry flood insurance in Lane County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 1,513 policies against 9,402 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 1.6% of all residential structures in Lane County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Lane County compares nationally
