Tazewell County, IL flood risk explained
Flood hazard in Tazewell County sits at the 84.4th 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 1.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Tazewell County's flood-insurance compliance gap
Out of 308 homes FEMA counts inside Tazewell County's mapped flood zone, 51 carry the flood policy federal law requires there — 16.6% compliance, short of full coverage. Looking beyond the mandated zone, 0.2% of all residential structures in Tazewell County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
