May 2025

Summer is right around the corner!

The Lake Hills and NW Lake Sammamish Sewer Upgrade Project team is preparing for another season of community events, and you’re invited! Meet us in Redmond over the next couple of months and to learn about the project, get your questions answered, and look at project materials.

Our first event is Bike Everywhere Day on May 14. Find our booths along the Sammamish River Trail near Dudley Carter Park between 6 and 9 a.m. and near the Marymoor Park entrance between 4 and 7 p.m. Join us to meet members of our team and learn about the project.

If we don’t see you at Bike Everywhere Day, we hope to see you at future events, including:

• Redmond Derby Days on July 12
• Movies at Marymoor Park - GoGreen Night in August
• Move Redmond Open Streets Festival in August

Designing large sewer upgrades take time. Design continues and construction is expected to begin in 2027.

King County continues to update the design of this sewer upgrade project to support the growing communities in Redmond and Bellevue. We are working with the City of Redmond, the City of Bellevue, and several state and federal agencies to move the project forward. Coordination with our partner agencies is necessary to make sure we install the new pipe in the safest way possible, limit impacts, and maximize improvements for people and the environment. 

Currently we anticipate construction will begin in 2027 and we expect to share more updates about the project schedule with the community later this year.

While the design team continues their work, the outreach team is available to answer questions about our project.

About the project

King County is working on a project to upgrade 4.5 miles of sewer pipe. King County will build the new pipe in trails, roads, and parks in Redmond. Due to a slowdown in the design and permitting processes, we now expect construction to begin in 2027. When complete, the new pipe will provide sewer service for 50 years or more.
