Snohomish County Completes Final Section of Lake Serene Emergency Bypass Nearly a Year Ahead of Schedule 


Public is invited to attend community meeting at boat launch on September 14 to celebrate milestone

EVERETT, Wash., September 12, 2017 – Together with local and regional partners, Snohomish County completed the design, permitting and construction of the final section of the Lake Serene outlet ahead of schedule. This new section connects the lake to the county emergency bypass drainage system that was built in March 2017. Completed almost a year ahead of the original schedule and prior to the rainy season, this new connection significantly reduces the risk of flooding on Lake Serene. Lakeside residents experienced flooding during periods of heavy rain in early 2017 due to a failing outflow pipe on private property.

“We’re pleased we were able to secure the five required permits much faster than initially anticipated,” said Will Hall, Surface Water Management Utility Director. “We also confirmed that the failed outflow pipe on private property is indeed blocked, making this an essential fix for future rainy seasons.”

To celebrate this milestone, Snohomish County Public Works will host a community meeting on Thursday, September 14. 

                Lake Serene Community Meeting

                When: September 14 from 4 – 6 p.m.; welcome remarks at 4:30 p.m.

                Where: Lake Serene Boat Launch, 4175 140th St SW, Lynnwood, WA 98087

                What: Celebrate the latest Lake Serene project milestone, meet with county officials and learn what to expect in the project’s next phase.

To further reduce flooding hazards for Lake Serene residents, the county will replace degraded infrastructure downstream of Serene Way. The county is currently working to obtain permits and design the final phase of this drainage improvement project. Construction is scheduled for 2018/2019. See Proposed Project Sketch to learn more.

Lake Serene is located in unincorporated Snohomish County, west of Highway 99 between Mukilteo and Lynnwood. For more information, visit the Lake Serene project website.
