Anoka County, MN: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Anoka County scores at the 92th 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 once every 2 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Anoka County's flood-insurance compliance gap
7.4% of the homes FEMA requires to carry flood insurance in Anoka County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 139 policies against 1,891 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.2% of all residential structures in Anoka County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Anoka County compares nationally
