Lake Hills and NW Lake Sammamish sewer upgrade
March 14, 2018
Expect short delays on West Lake Sammamish Parkway and residential streets beginning March 20
Crews working for King County’s Lake Hills and NW Lake Sammamish Sewer Upgrade Project are continuing field work activities to support final design. Starting March 20, crews will dig twelve potholes along West Lake Sammamish Parkway and throughout the project area to locate existing utilities.
Crews will work on the shoulder of West Lake Sammamish Parkway and the following residential streets:
- 172nd Avenue N.E.
- N.E. 34th Street & 179th Avenue N.E.
- 180th Avenue N.E.
- 177th Avenue N.E.
- N.E. 39th Court
You can expect to see single lane closures during each pothole location. Our goal is to limit delays to no more than five minutes.

The Lake Hills and NW Lake Sammamish sewer pipe has been serving Redmond and Bellevue for 50 years. The water you use travels down your drain to City sewer systems. The City’s pipes send wastewater to King County’s sewer system where it is carried to the Brightwater Treatment Facility in Woodinville for treatment.
King County is upgrading nearly 4.5 miles of sewer pipe in Redmond to meet the needs of your growing community. Construction is expected to begin in 2020. While the sewer pipe is under construction, King County will also install 1.5 miles of pipe to carry recycled water. When complete, the new pipes will provide reliable sewer service and an important connection for the potential future use of recycled water in the area.
