6th Avenue NE and NE 168th Street Water Main Project

In the southwest corner of our District, near the Lynnwood Link Shoreline South Light rail station, new development is planned on 6th Avenue, south of NE 155th. The District is taking the lead on upsizing the water main on 6th Avenue this summer.  The connections on NE 148th and NE 152nd Streets were installed in 2023; this summer the area on NE 168th Street at 25th Avenue NE will have its water main replaced.  All of these projects affect water movement in the southern part of our District.

On February 4, 2025, WSB Excavating and Utilities was awarded the project and began work on April 21st. Most of the work is on 6th Avenue NE between NE 145th Street and NE 155th Street; they began their work near NE 155th towards NE 145th Street.

Project Schedule:

As of June 2025:  WSB Excavating has completed the majority of the 12” water main work on 6th Avenue NE and are now working on connecting the services to the new water main, installing the fire hydrants, and making paving repairs on 6th Avenue NE.

As of August 2025:  WSB Excavating is currently transitioning to the NE 168th Street portion of the project. Here they will be installing an 8” DI (ductile iron) waterline along 25th Avenue NE, from NE 165th Street to NE 169th Street; connecting the existing 12” waterlines on NE 165th Street and NE 169th Street; and replacing the current 6” CI (cast iron) waterline. This portion of the project will improve fire flows, and create a better flow of water which will improve water quality and increase resiliency within the District.

There may be some time when WSB Excavating may be working at both locations at the same time.
