In Lake Oswego, the street sweepers and Public Works Operations are busy keeping our streets and waterways clean. Last fiscal year, the three street sweepers swept more than 6,400 miles of road, collecting enough debris to fill almost 16,000 40-gallon lawn trash bags.
Even with unreliable equipment, Lake Oswego meets its stormwater program and Municipal Separate Storm Sewer System (MS4) Permit regulatory requirements for street cleaning. Cleaning streets keeps water clean by preventing gravel and contaminants from entering waterways. In addition, cleaning streets helps prevent flooding and keeps our streets safer and less slick. The City sweeps curbed and guttered streets 4 times per year and major arterials more than 12 times per year.
