Oceana County, MI flood risk explained
Flood hazard in Oceana County sits at the 43.6th national percentile, 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 4 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Oceana County's flood-insurance compliance gap
15.6% of the homes FEMA requires to carry flood insurance in Oceana County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 35 policies against 225 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.3% of all residential structures in Oceana County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Oceana County ranks
Among the 3144 US counties FEMA scores for flood hazard, Oceana County ranks 1833 — 1 being the highest hazard nationally — and 1541 by population among all 3144 counties covered here, where 1 is the largest. Oceana County, Michigan is home to about 27,014 people across 538.106 square miles of land.
