NW Lake Sammamish Sewer Upgrade Project


An example of open-cut trenching we can expect
The King County Lake Hills/NW Sammamish Sewer Upgrade Project will seriously impact western Redmond with construction starting in 2021. It will take three years to complete.

"The sewer pipe is located underground directly beneath the Sammamish River Trail surface between N.E. 85th Street and N.E. 51st Street. To replace the pipe, crews will need to remove the trail surface.  It will encroach upon Marymoor Park.and private property. 

"Many trees have grown up round the the sewer pipe since it was installed 50 years ago.  Crews will need an area approximately 30-45 feet wide along the entire pipe route to safely install the new pipe. Plants and trees will be removed in these working limits.  Over the length of the 4.5 mile-long sewer route we expect to remove several hundred trees. 

"When work is complete, we will replant at least one tree for every mature tree that is removed.  For trees that are removed and are 30-inches-wide or larger, three new trees will be planted.  These guidelines are set by the City of Redmond."

 -- King County planner

I highly recommend you participate in the online open house to learn more about the project and give feedback. I've taken it and found it very useful. It is very well done.  

The following meeting is planned to review the project and gather additional feedback:
Wednesday, January 8, 2020
5:30 – 7 p.m. Redmond City Hall, Council Chambers
15670 N.E. 85th St., Redmond, WA 98052
On another note, during 2019 Derby Days the City Parks & Trails Manager said the Sammamish River Trail is planned to be widened. The Trail is on King County property and I wouldn't be surprised if the widening takes place during the sewer project.

  1. Good news that the trail will be widened. Does this include the trail going north by the senior citizen center?

  2. George, good question. I looked it up on the Open House page and found the answer under "Restoration."

    The planner stated: "We recognize that the trail is a popular route for recreation and commuting. Our goal is to put the trail back as good or better than we found it. When our work is complete, we plan to:

    Relocate as many maintenance holes off the trail as possible
    Plant new trees and shrubs to replace those removed
    Repave affected areas of the trail to at least the current footprint
    **Widen the trail between N.E. 85th Street and Leary Way**

    My concern is the impact to Dudley Carter Park. I've heard it could be a "landing spot" for their equipment. Unfortunately I didn't make the meeting to find out.
