Lake Hills and NW Lake Sammamish Sewer Upgrade Project
Online open house live until Jan. 31, 2020
There’s a lot of construction work planned for the Redmond area in the next few years. One of these projects is King County’s Lake Hills and NW Lake Sammamish Sewer Upgrade. King County needs to upgrade this regional sewer pipe that is undersized and aging.
This 4.5-mile-long sewer pipe is located underground in trails, roads, parks, and private property. Construction will take about three years to complete. We know this project will be disruptive to the Redmond community. Our goal is to make sure that when we start our work in 2021, you know what to expect ahead of time.

Final design is moving forward
King County continues to make progress on the project design. We’ve been working closely with local jurisdictions, including the City of Redmond, and partner agencies to get feedback on the final design. We’ve also been working closely with you to better understand your priorities and keep you informed of project updates.
Over the past year, we have:
- Completed the State Environmental Policy Act (SEPA) review process
- Refined Sammamish River Trail detour routes
- Made draft plans for how we’ll replace trails, repave streets and sidewalks, and replant trees and shrubs after construction
- Continued to coordinate with Tribes
- Begun acquiring permits from the City of Redmond, City of Bellevue and state and federal agencies
- Continued conversations with you to share the latest project information and incorporate your feedback into our design wherever possible
