Street Sweeping
The City sweeps public streets on a regular basis to help keep our roads and waterways clean. Street sweeping schedules and priorities may shift depending on severe weather conditions, traffic incidents or construction, or emergencies. Please note that moving, raking, or blowing leaves and debris into the street is not allowed. It slows down the street sweepers, can create hazardous driving conditions, and can clog our storm drains.

Pond Mowing
The City owns and maintains over 400 storm ponds. To ensure equitable service, Sammamish takes a systematic approach to pond mowing. The schedule for pond mowing is based on maintenance zones and we mow our ponds* once per year so we can access features of the ponds for inspections and maintenance. Because we mow our ponds regularly and systematically, individual requests for pond mowing are not accepted.
* Storm ponds that are part of the City’s Adopt-a-Pond program are either partially mowed or not mowed at all. Want to learn more about our Adopt-a-Pond program?
