Pierce County, NE: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Pierce County scores at the 20.5th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. 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. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Pierce County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Pierce County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.3% of all residential structures in Pierce County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Pierce County ranks
Among the 3144 US counties FEMA scores for flood hazard, Pierce County ranks 2542 — 1 being the highest hazard nationally — and 2634 by population among all 3144 counties covered here, where 1 is the largest. About 7,334 people live in Pierce County, Nebraska, spread over 573.249 square miles.
What to do next if you own or are buying in Pierce County
