Visit an online open house to review sewer improvement plans in Redmond


King County is hosting an online open house to enable people to review and comment on plans for its Lake Hills and NW Sammamish Sewer Upgrade Project in Redmond. The online open house is available through Wednesday, Jan. 31, 2018.


People interested in learning more about King County’s Lake Hills and NW Lake Sammamish Sewer upgrade Project are invited to participate in an online open house through Wednesday, Jan. 31, 2018. 

Because project construction will be noticeable to users of West Lake Sammamish Parkway, Marymoor and Idylwood parks, and the Sammamish River Trail when it begins in 2020, King County hopes people will review design plans and share input on ways to minimize construction-related disruption.

Community member feedback so far indicates people put a high priority on preserving summertime park and trail access, coordinating construction schedules with nearby schools, and workable detours for motorists, cyclists and pedestrians. People also value protecting plant and animal habitat. 

King County’s Lake Hills and NW Sammamish Sewer Upgrade Project entails upgrading nearly 4.5 miles of sewer pipe in Redmond to meet the needs of the growing community. 

In addition to adding more capacity, King County will also install 1.5 miles of recycled water pipeline as part of the project, which could expand potential use of this resource in the future. 

Additional information on the Lake Hills and NW Sammamish Sewer Upgrade Project is available online, or by contacting Kelly Foley at 206-477-8621.
