The St. Louis County Public Works Department is responsible for the removal of snow and ice from county roads, as well as some township roads and city streets based on interagency agreements. Snow removal performance can be affected by a variety of factors such as intensity and the duration of the snow event, temperature, wind and moisture content of the snow.
The goal of Public Works is to restore all county maintained roads to a passable condition within the shortest time possible after a snow event. To accomplish this, the department completes its snow removal process in accordance with the St. Louis County Public Works Department Snow Removal Policy. In general, the Public Works Department will not call-out or hold-over employees until there is an accumulation of 2 inches of snow on paved roads and 4 inches of snow on gravel roads. Roads serving higher average daily traffic (ADT) are given priority over lower ADT roads.
