Sandoval County, NM flood risk explained
Flood hazard in Sandoval County sits at the 84.3th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.4 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 Sandoval County
Homes with a federally backed mortgage inside Sandoval County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy.

Looking beyond the mandated zone, 1.1% of all residential structures in Sandoval County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
