Posting Date: 3/28/2017                

Contact: Michael Charles - Community Communications Officer

Phone: (206) 257-2175

PROJECT UPDATE (2/26/2018):

Crews are working on NW 98th Street. This work will continue for several weeks.

Customers can experience some noise due to heavy equipment from the hours of 7 a.m. to 6 p.m. Seattle City Light has received a noise variance permit to work under these hours.

Reminder to residents that trenching for conduits will occur in the public right-of-way (e.g. street and planting strips). This could include the landscaping and driveways in front of your house. Affected landscaping, vegetation and driveways will be restored. Crews are permitted to use these right-of-way areas as needed.

All traffic control plans associated with this project have been approved by the Seattle Department of Transportation (SDOT). The plans are audited from time to time, and will continue to be in compliance with SDOT standards and guidelines.


As part of Seattle City Light’s continuing investment to improve the electrical system in the Blue Ridge neighborhood, the utility has hired a contractor to install conduit and associated electrical work in parts of Blue Ridge and North Beach. Phase I of this work began in parts of the Blue Ridge neighborhood in early 2016 and is anticipated for completion in June 2017. Phase II will tentatively start in mid-to-late May 2017.


Map Update (2/26/2018)


  • Underground electrical cables were originally installed in Blue Ridge in 1971-1972. In 2012, a Seattle City Light contractor tested and where possible, injected the cables with silicone to extend their life. Approximately 60 percent of the cable was suited to injection. The remaining 40 percent must now be replaced.
  • All of Blue Ridge will have a nearly new, more reliable electrical system when the project is completed.
  • The cable in the conduit will allow for shorter restoration times when outages occur.


  • The contractor may be working in multiple locations at one time.
  • Construction will require sections of roadway in the construction zone to be closed to thru traffic while construction is in progress.
  • Driveway access to houses closest to the construction will be limited during working hours. Vehicles will be able to pass during non-working hours.
  • The project will not cause interruption to your mail delivery or garbage/recycling/yard waste service. Please leave your cans on the curb as you normally do and our crew will make sure that they are picked up by Cleanscapes.
  • Maintenance power outages are required to do the work safely. Affected residents will be notified in advance of any outage.
  • Trenching for conduits will occur in the public right-of-way (e.g. street and planting strips). This could include the landscaping in front of your house. Affected landscaping, plants and fencing will be restored. Crews have access to use this area as needed.
  • Blue Ridge streets that have been trenched will be restored and repaved. This does not include areas outside of the construction work zone.
  • All trenches will be covered with steel plates during non-working hours.
  • The contractor 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.
  • Customers can expect temporary parking and traffic restrictions. The contractor will work to limit traffic impacts.
  • City Light’s Resident Engineer will be on site daily to monitor the contractor.
  • Private service connections to homes are not included in this work. The homeowner is responsible for installing conduit in their private property.
