It seems like only yesterday that weekly street sweeping disappeared from Washington’s residential areas. The last sweeping season wrapped up on Halloween, giving drivers a few months of leeway when parking on these residential streets.

The sweepers and the restrictions are back. Residential street sweeping returns today, March 1, and runs through Oct. 31, according to the District Department of Public Works.

Posted signs identify the days and hours when parking restrictions are in effect to allow sweepers full access to the streets. Enforcement of these restrictions doesn’t begin until March 12.

Any residential streets without parking restriction signs are swept twice a month, as opposed to every week; cars don’t need to be moved on these streets.

Remember to follow whatever rules are posted on the signs and not just park if you see that a block has already been swept. The DPW warns that supervisors follow the sweepers and, as a result, some blocks might be swept more than once.
