The City of Darien follows a priority-based system for plowing streets.
- High-traffic arterial streets are plowed first, and if necessary, replowed until they are safe and passable.
- At that time, lower traffic collector streets are plowed.
- When both arterial and collector streets are safe and passable, the plows begin work on residential streets and cul-de-sacs.
It takes approximately four hours to plow all of the city’s streets once. Consequently, during heavy, ongoing snow, it could take several hours to get to an individual, residential street. Once all streets are open and passable, the City begins addressing other snow concerns, including cutting down large piles of snow at intersections which might create sight distance problems. Finally, after all the street work is complete, the City’s crews begin work clearing sidewalks along Plainfield Road, Cass Avenue and 75th Street. Learn more.
Please keep in mind that Plainfield Road, Cass Avenue and 75th Street are DuPage County roads and are not plowed by the City of Darien. Contact DuPage County Department of Transportation at 630-407-6900 with any questions.
