PROJECT UPDATE (6/28/2019)

Construction Work Areas (June/July 2019):

  • Crews have completed work on California Avenue SW (between SW 106th and 107th streets). The next phase of work will continue on California Avenue SW, heading south towards Marine View Drive SW/SW 108th Street.


Underground, direct buried cables in the Arroyo neighborhood are approaching the end of their useful life and will require new electrical conduit and cables. Seattle City Light has identified several areas within the Arroyo neighborhood that will require installing new conduits, vaults, and other associated work. Streetlights will also be replaced as part of this work.

  • This work will result in enhanced electrical reliability and efficiency.


  • City Light crews will be working in multiple locations at a time. Customers can expect temporary parking and traffic restrictions. Crews will work to limit traffic impacts.
  • Maintenance power outages are required to do the work safely. Affected residents will be notified in advance before any outage.
  • Trenching for conduits will occur in the public right-of-way (e.g. street and planting strips). Some sidewalk and driveway aprons will be affected. Trenches will be covered with steel plates or fenced off outside of construction work hours.
  • City Light crews will work closely with Seattle Department of Transportation's (SDOT) Urban Forestry group to ensure the protection of trees. SDOT staff may be onsite to monitor this work.
  • All affected areas will be restored and repaved, in accordance with SDOT guidelines.
  • Individual electrical service connections to new developments (homes/buildings) are not included in this work. The homeowner is responsible for installing conduit in their private property. Learn more at
  • Crews will be installing 3000K LED streetlights in several areas. The Cleveland style streetlight fixture will be installed in smaller, residential streets. The Arieta fixture will be installed along Marine View Drive. These installations are anticipated to occur after civil construction is completed.
