Arroyo Conduit Installation

Map showing area of work in the Arroyo neighborhood

Project Description

Underground, direct buried cables in the Arroyo neighborhood are approaching the end of their useful life and will require new electrical conduits 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.

Location

Crews are working in the Arroyo and Arbor Heights neighborhoods in southeast Seattle.

What's Happening Now?

Project Update (Jan. 2021): 

  • Crews are working on Marine View Drive SW (between 39th Avenue SW and SW 110th Street). They will be installing underground electrical conduits, new electrical vaults and streetlights in the public right-of-way.  
  • The work associated with this project will include trenching in the public right-of-way, which may affect the landscaping, driveway approaches and vegetation in front of your house. All affected landscaping, driveway approaches and vegetation will be restored, per Seattle Department of Transportation (SDOT) standards and guidelines. 
  • The Jan. 14 planned outage was rescheduled due to crew availability from the windstorm.  The outage will be rescheduled in late February 2021. Affected customers will be receiving a new notice in the mail. We apologize for the inconvenience.

Community Benefits

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

Anticipated Impacts

  • 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 http://www.seattle.gov/light/electricservice/application.asp.
  • 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. See photo below:

Examples of the streetlights that will be installed in the Arroyo area

  • Construction Start: May 2018
  • Duration: Until 3rd quarter 2021
  • Daily Work Schedule: Mon-Fri, 9 a.m.-3 p.m.; weekends 9 a.m.-6 p.m. Some evening work may be required.
