Is Pulaski County, IL in a flood zone?
FEMA's National Risk Index puts Pulaski County's flood hazard at the 15.1th percentile nationally — among the lowest flood hazard in the country — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 4.7 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Pulaski County's flood-insurance compliance gap
Pulaski County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Pulaski County, not just the ones FEMA mandates, 1.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
