Susquehanna County, PA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Susquehanna County scores at the 71th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. 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 1.7 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Susquehanna County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Susquehanna 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, 19.4% of them do — 131 active policies against 674 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 1.1% of all residential structures in Susquehanna County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
