On November 21, 2007, the DC Department of Public Works (DPW) announced that weekly, (signed) residential mechanical street cleaning will end for the season Friday, November 30, 2007.  "No parking/street cleaning" restrictions will be lifted and motorists may park along posted, alternate-side, daytime street sweeping routes without being required to move their cars on street-cleaning days.  

Residential street sweeping is suspended for public safety concerns during the winter. Sweepers emit a fine spray of water to keep dust down as they sweep; but when the temperature is at freezing or below, sweeping is discontinued to prevent freezing and accidents to vehicles and pedestrians.

Overnight sweeping scheduled for the District's major roadways, such as Pennsylvania, Georgia, Constitution, Independence Avenues and others, will take place as usual all winter, weather conditions permitting. Motorists are urged not to park in these areas during the posted overnight sweeping hours.  

By suspending the street sweeping program, DPW personnel will focus on leaf collection, which began November 5, and the upcoming snow removal season. Residents and business owners will be notified when street sweeping resumes again in the spring of 2008.
