Kennebec County, ME: flood risk, in FEMA's own numbers

On FEMA's National Risk Index, Kennebec County scores at the 80.1th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.6 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

Homes with a federally backed mortgage inside Kennebec County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 13.1% of them do — 179 active policies against 1,368 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.5% of all residential structures in Kennebec County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
