How much flood risk does Lincoln County actually carry?
Lincoln County lands at the 14.4th 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 7 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Lincoln County's flood-insurance compliance gap
Lincoln County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Lincoln County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
