Seattle Public Utilities (SPU) and Seattle Department of Transportation (SDOT) are regularly sweeping over 90% of Seattle’s arterial streets. City crews sweep 32 night routes and 7 day routes throughout the year, with 3 additional routes swept during leaf season.
Note: Scheduled sweeping days and locations may vary due to labor and equipment resources, emergency clean up needs, and weather conditions.
Support Clean Waterways: Pollutants build up on streets and wash into local waterways when it rains, and sweeping removes some of this debris before it is washed down the drain. Annually, around 330,000 pounds of pollutants are prevented from potentially entering our local waterways.
Keep neighborhoods healthy and clean: Sweeping removes trash and city grit for a more appealing place to live, work, and visit. Seattle sweeps over 26,000 miles of street every year to facilitate this.
Keep Seattle moving and safe: Sweeping improves car and bike lane safety and reduces flooding by clearing stormwater inlets
