PROJECT UPDATE (12/22/2017)

The pilot program has been completed. City Light is moving forward with the King Luminaire K56 Cleveland fixture in the Blue Ridge neighborhood. Construction is anticipated to start in early to mid-2018 and customers will be notified in advance of this work.


Seattle City Light is working to improve customer safety, reduce carbon emissions and conserve resources by converting streetlights from high-pressure sodium lights to energy-efficient light-emitting diodes (LEDs). In late October 2017, City Light crews will conduct a pilot streetlight project along NW Blue Ridge Drive.



The Blue Ridge Streetlighting Infrastructure Replacement project is part of a 10-year street light improvement plan that will replace 204 existing streetlight poles, foundations, wiring, and fixtures in the neighborhood. The work was prioritized due to increased streetlight failure in the Blue Ridge area.

The existing high-pressure sodium streetlight fixtures will be replaced and updated with safer, reliable and more efficient LED fixtures. The K56 Cleveland LED fixture will be used as part of a pilot project in late October 2017 in the 2300 block of NW Blue Ridge Drive. The new fixture will be analyzed for luminaire performance and compliance with roadway lighting guidelines.

In late October 2017, the K56 Cleveland LED fixture will be piloted in NW Blue Ridge Drive.

After City Light has analyzed the results from the pilot project, crews will return to the Blue Ridge neighborhood to replace the existing streetlight infrastructure. This work is anticipated to start in early to mid-2018 and customers will be notified in advance of this work.


  • The new LED streetlights will make residential streets safer by increasing their visibility at night.
  • LEDs reduce greenhouse gas emissions during manufacturing as well as when they are in use. Additionally, about 20,000 tons of reduced carbon emissions per year are the result of fewer service vehicle trips.
  • The new lights will shine directly onto the roadway. These fixtures are dark sky friendly.


  • There are no maintenance power outages planned.
  • Minimal traffic and parking impacts are expected in the immediate work area.
  • Customers can expect some night work from light testing


Construction Start: Tuesday, October 31

Duration: Up to one week

Daily Work Schedule: Mon - Fri from 9 a.m. - 5 p.m. with night work
