Our street sweeping efforts result in improved air and water quality, and keeps our community clean. Street sweepers remove debris from Village streets and prevent it from entering the storm drains. Sweeping operations will take place after winter storm events to meet DRCOG (Denver Regional Council of Governments) air quality emission reduction requirements. Sweeping begins at 7:30 a.m. in residential areas and 8:30 a.m. in commercial areas.
