Smith Cove work continues this week

King County’s contractor, Stellar J, is continuing construction on the new Magnolia Wet Weather Storage Facility at Smith Cove. 

This 1.5-million-gallon underground tank will store excess flows of stormwater and sewage when heavy rains fill pipes, reducing untreated overflows to Puget Sound. 

During the week of November 2nd, Stellar J will re-install a Seattle City Light streetlight in front of the storage tank site on 23rd Avenue West, south of the Magnolia Bridge. The light was temporarily removed to accommodate construction. 

Work will occur on the sidewalk and parking strip on the east side of 23rd Avenue West. As needed, flaggers will direct people around this work, which will take place weekdays from 7 a.m. to 5 p.m.

Crews are also installing equipment in the building that sits atop the storage tank, and landscaping at the site is expected to begin in November.

In the coming weeks, King County’s contractor and a Seattle City Light crew will add power to the underground flow structure on 32nd Avenue West. Crews will work mostly near the shoulder on the east side of the street. A Seattle City Light truck will be there during portions of this work.

As needed flaggers will direct people around the work area, as needed, on weekdays, from 7 a.m. to 5 p.m.
