Art FLOWs back to Ballard

Temporary art series entitled FLOW along 24th Ave NW and NW 56th St

As work continues in Ballard, art “FLOWs” back to the neighborhood. We’re super excited to announce new temporary public art in the series entitled FLOW located at 24th Ave NW and NW 56th St created by Amanda Lee. In Amanda’s words, these mural panels called Net Cord Landscapes take inspiration from “reef net fishing and the nettles that provide the fibers,” a nod to the neighborhood’s fishing and maritime heritage. The Ship Canal Water Quality Project aims to be a “net” that catches stormwater for treatment to protect our waterways and marine life for generations to come.

According to her website, Amanda Lee is a multidisciplinary artist specializing in printmaking, book arts, and photography. She creates art that investigates the intersection of Indigenous knowledge systems with print media and book art theory. You can see more of Amanda Lee’s artwork on Instagram @amandaleeprints or visit her website.

We invite you to learn more about the art showcased alongside the Ship Canal Water Quality Project on our website’s Public Art page.

Seattle Public Utilities and King County Wastewater Treatment Division are building the Ship Canal Water Quality Project (SCWQP) to significantly reduce the amount of polluted stormwater (from rain) and sewage that flows into the Lake Washington Ship Canal, Salmon Bay, and Lake Union from our sewer system.


Ballard update

A few weeks ago, we turned our 7-foot-diameter tunnel boring machine (TBM) westward onto NW 56th St after tunneling under 24th Ave NW. The TBM is now tunneling under NW 56th St and making good progress on the journey to 28th Ave NW. Learn more about the Ballard TBM from our June special edition email.

Contractor crews continue work along 24th Ave NW, NW 56th St, and 28th Ave NW. The tunnel boring machine (TBM) is currently tunneling west along NW 56th St and is expected to reach the intersection of 28th Ave NW and NW 56th St later this year. Crews have begun installing pipe connections and drainage structures at 28th Ave NW and NW 56th St.

At the pump station construction site, crews are working on electrical systems. Inside the pump station, a range of activities are underway on each floor. Workers are building and installing structural pieces as well as adding insulation to the walls. Also, the contractor has installed the discharge pipe from the pump station site across Shilshole Ave NW and will continue utility work in and near Shilshole Ave NW for the next few months.

You should anticipate:

  • Parking restrictions, intermittent road closures, and local access only along 24th Ave NW, NW 56th St, and 28th Ave NW
  • Trucks bringing materials on-site and off-site
  • Noise, dust, and vibration typical of a construction site
  • Vehicle, pedestrian, and bicycle detours around the area
  • Increased traffic in the area as residents and commuters adjust to detour routes

For your safety and the safety of our crews, please watch out for equipment and signs in the area. Travel slowly through active construction areas and follow directions from flaggers and signs.

Looking ahead

We will be staffing a table at the Ballard Regional Center Plan Drop-in session at the Seattle Public Library, Ballard Branch on September 22 from 5 PM to 7 PM. The event is open to the public. Feel free to stop by if you’d like to chat with project staff and learn more about what’s happening in the neighborhood.

Our next update will be sent out later this fall, but there is still a lot happening in Ballard! If you’d like to keep getting monthly updates focused on Ballard, send us an email at SPU_ShipCanalProject@seattle.gov and we will add you to the email list.

Other project sites:

East Ballard, Fremont, Queen Anne, Wallingford

Work in these neighborhoods has been relatively quiet. Crews may still show up periodically for minor inspections and restoration work. We will be back in 2027 when the storage tunnel becomes operational.
