Project overview

PSE is upgrading the natural gas system in Wallingford and Green Lake. The work involves replacing the existing natural gas main, installed in 1979, with new, corrosion-resistant plastic pipe. We’ll also be replacing individual service lines to some homes and businesses.

We’ve been working proactively with the Seattle Department of Transportation (SDOT) in planning the timing of our construction to commence shortly ahead of SDOT’s Green Lake and Wallingford Paving and Multi-Modal Improvements project.

This joint coordination is an effort to minimize impacts to the local community, while maximizing cost savings and avoiding rework by completing PSE’s work under the road prior to SDOT repaving the street. Learn more about SDOT’s project here: www.seattle.gov/transportation/greenlakepaving.htm

Construction schedule
  • Work hours are generally Monday through Friday, 8 a.m. through 4 p.m.
  • Saturday work has been added to the Wallingford-area project schedule
  • We’ll keep the local community updated if the construction schedule changes
What to expect
  • To prepare for this work, crews will be surveying the project area and marking current underground utilities with brightly colored paint or flags. These markings are temporary and will disappear on their own.
  • Signs and traffic control flaggers will guide vehicles and pedestrians safely through the work zone.
  • Crews will maintain access to driveways whenever possible, in coordination with impacted neighbors.
  • Curbside parking will be impacted as the crews move along the project route. “No parking” signs will be placed in the work area prior to parking restrictions, and we’ll do our best to minimize the time and area impacted.
  • Typical construction noise from trucks and heavy machinery.
  • As part of this work, some customers will have the gas service line to their home or business replaced, requiring a short interruption of natural gas service. We’ll provide affected customers with more information in advance of the service line work occurring on their property.
  • You’ll notice temporary patches in the road and/or sidewalk after crews have completed installation of the new pipe. These temporary patches will remain until a contractor crew returns to complete the final road and/or sidewalk restoration. The restoration schedule is dependent upon weather, permitting and crew availability.
