Is Schuyler County, IL in a flood zone?
FEMA's National Risk Index puts Schuyler County's flood hazard at the 8.2th 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 1.5 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
