Arroyo/South Arbor Heights Conduit Installation Project Begins This May

Starting in May 2018, Seattle City Light will be working in the Arroyo/South Arbor Heights area to install new electrical conduits, vaults and streetlights. This work is needed to replace aging underground, direct buried cables in the neighborhood.

Construction will start at California Avenue SW, between SW 106th and 107th streets. To follow the progress of this work, please visit our website.

What You Can Expect:

City Light crews will be working in multiple locations at a time. Construction will start at California Avenue SW, between SW 106th and 107th streets. Customers can expect temporary parking and traffic restrictions. Crews will work to limit traffic impacts.

Example of crews trenching for new conduit.

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.

Maintenance power outages are required to do the work safely. Affected residents will be notified in advance before any outage.

Timing & Coordination:

  • Civil and electrical construction is estimated to last approximately 18-20 months. Additional streetlight work will follow.
  • Daily work hours are from Mondays through Fridays, 9 a.m. to 3 p.m., and weekends from 9 a.m. to 6 p.m. Construction could extend beyond these hours, as needed.

Customers can contact David Mannery, Senior Electrical Service Representative at (206) 386-4245 or david.mannery@seattle.gov.

Repairs Along I-5 to Cause Rolling Slowdowns April 25-28

Seattle City Light crews are planning emergency repair work to restring electrical wires pulled down across Interstate 5 by last Saturday’s car/pole collision at NE 125th Street. The work will impact traffic on Interstate 5. Drivers should expect delays and consider using alternate routes.

To complete the work safely, crews must intermittently stop traffic in both directions of I-5 overnight for up to three nights. Traffic may be stopped up to 25 minutes at a time between State Route 520 and NE 205th Street as crews pull power lines across the highway.

Rolling slowdown details:

  • Work will be performed Tuesday, April 25, through the morning of Friday, April 28.
  • Crews will intermittently stop traffic on I-5 between SR 520 and NE 205h Street from 11:59 p.m. to 4 a.m.
  • Washington State Patrol troopers will assist with traffic control and escort drivers through the construction zone.

If you have questions/concerns during normal work hours, City Light’s point of contact is Mark VanOss, Sr. Public Relations Specialist, at (206) 684-3279 or mark.vanoss@seattle.gov. If your question is urgent, leave a message at (206) 386-4233 and you will be contacted.

City Light Completes Streetlight Safety Upgrades in Holly Park

Seattle City Light recently completed the final phase of work in the Holly Park neighborhood to upgrade the streetlight electrical grounding system. This work ensures that all streetlights continue to work properly and safely by reducing the risk of contact voltage through improved grounding.

A map outlining the phases of work in Holly Park.

Grounding is installed on electrical systems to ensure safety for anyone who may come in contact with elements of the system. Contact voltage can occur on metal streetlight structures, or other equipment that can conduct electricity and become energized. No contact voltage problems have been found at Holly Park during the past three years of inspections. Testing is completed annually to make sure all electrical equipment is safe.

Contracted crews completed the final phase of this project in October 2016. As safety for customers is Seattle City Light’s first priority, the utility will continue to test all metal streetlights and associated structures in its service territory for contact voltage annually and report on the findings.

For more information about this project and others in your neighborhood, please visit Seattle City Light’s construction website. Search for utility construction projects in your area by neighborhood, address and ZIP code.

Streetlight Inspection Will Cause Rolling Slowdown on Ballard Bridge

Seattle City Light plans to inspect streetlights on the Ballard Bridge following the Seattle Department of Transportation’s seismic upgrades. The inspection is scheduled for Thursday, Dec. 17 starting at 7 p.m. and ending at 6 a.m. on Friday, Dec. 18. The location of the inspection can be found here: BallardBridgeMap

Single northbound and southbound lane closures on the bridge will be necessary. Motorists should expect rolling slowdowns in the direction of the affected lane. Only one lane at a time will be closed. Work will start in the southbound lane and end with the northbound lane. One quarter of the streetlights on the bridge will be out at a time. Spotters will assist any pedestrians and cyclists.

Inspection of the streetlight system is needed to close the construction contract and transfer ownership of the lights to Seattle City Light. Customers can contact: Tom Borek, Streetlight Engineer, (206) 684-4920, tom.borek@seattle.gov. If you are a member of the media, please contact Scott Thomsen, External Communications, (206) 615-0978, scott.thomsen@seattle.gov

 

City Light Completes Streetlight Conversions at Seattle Center

Crews finish concrete work for the streetlight infrastructure upgrade at Seattle Center.

Seattle City Light has completed the conversion of streetlights along the perimeter of Seattle Center to LEDs and its former 480-volt power supply to a 120-volt system.

As part of the overall Mercer Corridor project, the streetlight upgrades will improve safety and reliability.

Seattle Center was one of the few remaining areas in Seattle that still used a 480-volt system to power streetlights. Construction began in mid-to-late February, and lasted approximately five months.

The project area.

The upgrade will ensure all streetlights continue to work properly and safely to meet current safety guidelines. This work is one of several strategic investments by City Light to improve customers’ experience and meet customer’s electricity needs while also efficiently managing the energy system. The project also consisted of improvements to sidewalks and ADA curb ramps.

Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.
