How much flood risk does Logan County actually carry?
Logan County lands at the 67.7th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.1 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
Logan 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 Logan County, not just the ones FEMA mandates, 0.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Logan County against the rest of the country
Logan County sits at rank 1062 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 1068 of 3144 by population (1 is biggest). About 46,085 people live in Logan County, Ohio, spread over 458.508 square miles.
Your street may differ from Logan County's average
FEMA counts 24,783 residential structures in Logan County overall, 224 of them carrying some form of NFIP coverage — but a lender or insurer cares about one parcel, not that county total.
