Planned power outages for North City, Hillwood, and Richmond Beach for system upgrades

Seattle City Light plans to increase reliability in two sections of its service territory in Shoreline by injecting aging underground electrical cable with silicone. Maps are posted below.

Up to three power outages per customer are required to do the work safely. Customers on the streets will be notified directly by Seattle City Light. The project starts this week and all neighborhoods are expected to be completed within eight weeks.

City Light will be upgrading the aging electrical cable in sections of North City, Hillwood, and Richmond Beach, working with a company called UtilX during construction.

UtilX will test, and where possible, inject underground cables with silicon to fill cracks in the cable insulation. The work will extend the life of the cable and improve electrical reliability.

We have successfully used this lower-impact, cost-effective method of cable rejuvenation on 34 previous projects. If cables are not suited for injection, they will be replaced at a later time.

The crews work Monday to Friday from 8:30am to 4:30pm. Work will not occur during holidays on Nov. 11, Nov. 27 or Nov. 28.

Up to three power outages lasting about 8 hours are necessary to do the work safely. Outages will not occur on consecutive days. All affected customers will be notified the Thursday before the next week’s outage. The outage dates and times will be specified on the individual notifications to neighbors.

In the case of unseasonable cold weather, work will be postponed.

Some traffic and parking impacts are expected in the immediate work area. Flaggers will be used where needed on residential streets.

Crews will be careful to try to maintain access to driveways.
