The City’s street cleaning program removes dirt and debris from City streets to provide a healthy, safe, and attractive environment for motorists, bicyclists and pedestrians. The Pennsylvania Department of Environmental Protection permit and some federal requirements for operating a combined sewer system mandate street sweeping to protect water quality. Regular removal of leaves and debris by City street sweepers is necessary to prevent storm drains from clogging, which can result in localized street flooding. Street cleaning protects water quality by removing trash and litter annually that would otherwise end up in local streams and add more burden on the sewer system. Street cleaning begins on April 1st and ends on October 31st each year. All Street Cleaning Restrictions will be enforced in all parking areas, including Loading Zones and Residential Parking Zones. Look for nearby street signs that list the time of street cleaning (typically a two hours restriction on the designated day). You must move your vehicle during that time. BPA parking enforcement officers work in conjunction with the street sweeper and ticket any vehicles in the way of the street sweeper.
