How much flood risk does Noble County actually carry?
Noble County lands at the 31th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard 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.
Mandatory flood insurance compliance in Noble County
3.5% of the homes FEMA requires to carry flood insurance in Noble County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 3 policies against 87 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Noble County, not just the ones FEMA mandates, 0.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
