Join us for a virtual neighborhood meeting
Thursday, September 30, 2021
5:30 – 7pm
In 2019, King County started a process to acquire permits for this project from the City of Redmond. We recently submitted updated project plans to the City for their consideration. We invite you to join King County and the City of Redmond for at a virtual neighborhood meeting to get the latest information on:
- Project schedule
- Sammamish River Trail detours
- Road closures and detours
- Fish and wildlife protection
At the meeting, we will provide closed captioning and interpretation in American Sign Language, Arabic, Cantonese, Hindi, Mandarin, Russian and Spanish. We’ll also post a recording of the meeting to our website afterwards.
Construction expected to begin in 2024
Due to slowdown in the permitting process, construction has been delayed. We now expect construction to begin in 2024. Learn more in our summer newsletter .

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 working on a project to upgrade 4.5 miles of this sewer pipe. King County will build the new pipe in trails, roads and parks in Redmond. This project is necessary to meet the needs of your growing community. Construction is expected to begin in 2024 and may impact your daily routine. When complete, the new pipe will provide sewer service for 50 years or more.
