CITY AND COUNTY OF DENVER - STREET SWEEPING PROGRAM Denver’s residential streets are swept once a month from April through November.*  This helps to clean neighborhoods and improve our water and air quality.  But we can’t sweep under parked cars, so we need your cooperation to move your car on sweeping day.  Street sweeping schedule signs are posted so you can tell at a glance which day is sweeping day on your block.  The sign identifies the sweeping day for that side of the block.  The other side of the streets will be swept on a different day. * Neighborhoods with little on-street parking demand do not have these signs and streets are swept regularly without advance notice or parking tickets.

Sweeping Year Round   Denver’s Street Sweeping program has four basic sweeping components: posted sweeping, non-posted sweeping, post -snow sweeping and special event sweeping.   Posted, year-round sweeping of Downtown and arterial streets totals about 400 miles of road, and is done mainly at night. This sweeping occurs up to 5x per week on the main downtown streets and once every other week on major arterials, weather permitting.  Posted, seasonal sweeping and non-posted seasonal sweeping totals approximately 5,100 lane miles of streets and takes place monthly April through November between the hours of 8am and 5pm, Tuesday through Friday.  All streets are swept but not all streets have parking restrictions. These routes include residential streets, thoroughfares and arterials, as well as business districts and industrial areas.   Post-snow sweeping addresses major thoroughfares and some arterials (A & B routes) to reduce air quality impacts of snow control materials, and is usually done within 4 working days of the snowfall, weather conditions permitting. This sweeping covers at least 50% of the 1,800 lane miles of snow routes.  Special event sweeping is typically done during business hours as close to the event date as possible.
