Street sweeping is an important part of the City’s City's NPDES MS4 pollution prevention and good housekeeping program. Sweepers run every day on a rotating schedule unless snow is on the ground. On average, city streets are swept about 26 times each year.
In the fall, sweepers run more often in neighborhoods with many trees. They are busiest in the spring after the snow melts and again in the fall. On average, sweepers remove almost 5,000 cubic yards - or about 700 tons - of leaves, dirt, and other debris from our streets each year.
Street sweeping helps protect water quality and wildlife. It prevents oil, metals, trash, and other harmful materials from washing into creeks and streams.
The City’s Clean Water Fee pays for street sweeping services.
Non‑Routine Sweeping Services
The City also provides sweeping services for special situations:
- Citizens can request cleaning for a section of street or storm drain.
- Streets are swept before and after special events.
- Areas at the bottom of hills are swept after heavy rain to clear debris that collects on storm drains and contribute to localized street flooding.
- Streets are swept within 24 hours after they reopen roads following repair work.
