During a snow event, plows make multiple passes, with the initial pass prioritizing access for emergency vehicles. As snow accumulates, salt crews treat all main County roads, emergency routes, and primary neighborhood streets, and plowing and salting continue once snowfall reaches three inches. After the storm ends and priority routes are clear, crews plow neighborhood roads and apply abrasives to hills, intersections, and areas around schools. Depending on the storm duration and severity, full roadway clearing may take several days.
