Is Marquette County, WI in a flood zone?
FEMA's National Risk Index puts Marquette County's flood hazard at the 43.5th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 3 years. 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
15.7% of the homes FEMA requires to carry flood insurance in Marquette County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 34 policies against 217 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Marquette County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
