Is Laclede County, MO in a flood zone?
FEMA's National Risk Index puts Laclede County's flood hazard at the 61.4th percentile nationally — 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 3.4 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
