How much flood risk does Providence County actually carry?
Providence County lands at the 96.6th percentile of FEMA's National Risk Index for flooding, "Relatively High" territory — well above 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 3 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Providence County
58.1% of the homes FEMA requires to carry flood insurance in Providence County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 377 policies against 649 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Providence County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
