Project update

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.

For a detailed map of pothole locations and more on what to expect, please see the latest update .

Project description

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.

King County está trabajando en un proyecto para actualizar 4.5 millas de tuberías de alcantarillado en la zona donde usted vive. King County construirá la nueva tubería en senderos, caminos y parques en Redmond (vea el mapa en el reverso). Este proyecto es vital para satisfacer las necesidades de su comunidad en crecimiento. La construcción puede afectar su rutina diaria. Se espera que la construcción comience en 2020. Mientras se estén construyendo las tuberías de alcantarillado, King County también instalará 1.5 millas de tuberías para transportar agua reciclada. Cuando se finalicen las obras, las nuevas tuberías proporcionarán un servicio de alcantarillado confiable y una conexión importante para el posible uso en el futuro de agua reciclada en la zona. Si tiene preguntas o inquietudes, comuníquese con Kelly Foley al 206-477-8621. Se le puede proporcionar un intérprete sin costo alguno.
