Sharp County, AR Flood Zone & Flood Risk Data
Sharp County, AR: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Sharp County scores at the 66.3th 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 twice 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.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Sharp 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, 9% of them do, 47 active policies against 524 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.5% of all residential structures in Sharp County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
