We clean about ninety percent of San Francisco streets with mechanical sweepers. We cover 150,000 curb miles and remove 25,000 tons of litter and debris every year. Generally, we sweep residential streets weekly or twice per month and sweeps commercial areas at least once per week. Mechanical sweepers remove litter from your neighborhood and shopping corridors and also prevent grime and pollutants from entering the City's combined sewer system and therefore reduces the amount of pollutants entering the San Francisco bay and Pacific Ocean!
In order to successfully sweep our streets, residents must move their cars and property owners must make sure the tree in front of their home is trimmed up to 14 feet.
