14 <br /> <br />Cass County Highways: Snow Removal Routes <br />Cass County has prioritized roads to assist in such issues as maintenance, striping, and snow removal. Priorities <br />are used to determine which roads are plowed first and the schedule for which maintenance or construction <br />projects will be completed. Priorities are developed by the County Engineer by considering average daily traffic <br />volumes, pavement condition, as well as important points of need such as schools, cities, and commerce. Map 2 <br />displays the priorities listed below: <br /> <br />Key Commuter Routes: Plowing used in combination with abrasives and/or deicing chemicals over entire route <br />as determined appropriate. Objective is to complete first pass in both lanes with plow and/or abrasive/deicing <br />chemicals by 7:00 AM following a normal snowfall. During operations hours, plows operate when there is a <br />significant accumulation that a plow can remove. <br /> <br />Secondary Commuter Routes: In addition to plowing the entire route, abrasives and/or deicing chemicals used <br />at curves, intersections and extensive build-up areas as required. Objective is to complete first pass in both <br />lanes with plow and/or abrasives/deicing by 9:00 AM following a normal snowfall. During operation hours, <br />plows operate when there is a significant accumulation that a plow can remove. <br /> <br />Gravel Surfaced County Routes: Clearing by plowing. Generally abrasives and deicing chemicals are not used. <br />Objective is to complete a single pass with plow by 1:00 PM following a normal snowfall. Supervisor may elect <br />not to plow for very light snowfalls or when unfrozen gravel conditions exist. Generally plows operate when <br />there is an accumulation in excess of 3 inches. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
