Residential Street Sweeping To Begin Mar. 1
The 2013 residential street sweeping season begins Friday, March 1, announced the DC Department of Public Works today. Signs are posted that identify the days of the week and hours of the day when parking restrictions will be enforced so the sweepers can clean the streets effectively. Parking enforcement of residential sweeping violations will begin Monday, March 11, to give motorists a few days to get used to the parking restrictions.
“The residential street sweeping program is among our most successful operations to keep DC streets clean,” said DPW Director William O. Howland, Jr. “We have expanded it over the years to accommodate more and more residents willing to move their cars to allow the sweepers access to the curb lane where debris and pollutants collect. We also want to make sure commuters and visitors are aware that the parking restriction applies to all motorists and a $30 ticket can be issued for violating the restriction.”
Mr. Howland noted that beginning in 2012, DPW established March 1 through October 31 as residential street sweeping season and this information appears on the signs posted where the program is in effect.
He cautioned motorists to avoid parking along sweeping routes before that day’s restriction ends. “A supervisor follows behind the sweeper and may require the block to be swept again, so no one should park until the end of the posted sweeping period,” he said.
Beginning March 11, parked cars also may be towed to allow the sweepers access to the curbside. Generally, parking is prohibited for two hours while sweeping is underway.
DPW street sweepers cover about 4,000 lane miles monthly, removing litter and pollutants by brushing them onto a conveyor system, which transports the material into a debris hopper. The sweeper also emits a fine spray of water to help control dust. In addition to sweeping residential streets during spring, summer and fall, DPW also sweeps commercial streets overnight year-round, and parking restrictions also apply.

Street cleaning, and the alternate side parking that comes with it, begins today. Fortunately, if you forget to move your car this week, ticket enforcement will not begin until next week (March 29th). You can read more details from the DPW announcement
