Project overview

In order to deliver safe and reliable energy to our Seattle customers, PSE recently upgraded the natural gas system in Wallingford and Green Lake. The work involved replacing the existing natural gas main, installed in 1979, with new, corrosion-resistant plastic pipe.


Wallingford-area natural gas upgrade project

  • Gas work: Gas main installation along the entire route is now complete.
  • Road and sidewalk restoration:
    • Our contractor crews from AA Asphalting, Inc. have completed temporary restoration along the project route.
    • Seattle Department of Transportation (SDOT) will be completing final road restoration activities on North 50th Street as part of their Green Lake and Wallingford Paving and Multi-Modal Improvements Project.
    • AA Asphalting, Inc. will complete final road restoration as part of PSE’s natural gas work, on all other portions of the project route. We expect PSE’s final road restoration will begin in spring of 2020 and continue into summer.
  • Refer to the map for detailed information and a project timeline.

Other projects in the area

We’ve been working proactively with the Seattle Department of Transportation (SDOT) in planning the timing of our construction to begin 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

The Washington State Department of Transport (WSDOT) also has road improvement work in the general vicinity. Learn more about their work here: wsdot.wa.gov/projects/index/highway/sr-99
