Seattle City Light will be upgrading the underground electrical system in the Hillcrest Development neighborhood beginning September 9. To see the general project boundaries, please refer to the Hillcrest Development map.
The electrical cable in the Hillcrest neighborhood is aging. As underground cables age, the protective insulation deteriorates. When a crack forms and water or dirt reach the wires, it can lead to an unplanned power outage. Seattle City Light is working with a company called UtilX to help avoid such outages by using a silicon injection process. The silicon fills the cracks and extends the life of the cable. If cables cannot be injected, they will be replaced at a later time.
The overall process – including the replacement of splices and elbows that connect the cables – will improve the reliability of the electrical service in the Hillcrest Development neighborhood. Since 2009, we have successfully used this method in 45 other neighborhoods in our service territory.
What You Can Expect:
- Planned power outages so crews can safely do the work
- Up to three outages; the outages will NOT occur on consecutive days
- Notification by door hanger the Thursday before the outage is scheduled to take place
- The outages will last about eight hours
- Work hours are 8:30 a.m. - 4:30 p.m. from Monday – Thursday
- The entire project will be complete in approximately three weeks
- There will be some traffic and parking disruptions in the immediate work area, but it will be carefully signed
- Work will be done at each vault and trucks will move after each hour
- Flaggers will be used on residential streets. Crews will be careful to maintain access to driveways
