Seattle City Light will be upgrading the underground electrical system along Ambaum Boulevard SW starting in early November. As underground cables age, their 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 Novinium to help avoid such outages by using a silicone injection process to upgrade the cables. The silicone fills the cracks and extends the life of the cable and improves reliability for your electrical service.
Crews will be entering electrical vaults in the neighborhood and testing the cable to determine if the injection process can work. If the cable condition is satisfactory, crews will inject the silicone into the lines. If cables canít be injected, they will be replaced at a later time.
Residents can expect:
-Planned power outages so crews can work safely
-Up to (but no more than) six planned outages and NOT on consecutive days
-Notification by door hanger the Thursday of the week before the outage
-Outages lasting about eight hours
There will be some traffic and parking disruptions in the immediate work area, but it will be carefully signed. Work is done at a vault and trucks move on after about an hour. Flaggers will be used where needed on residential streets. Crews will be careful to try to maintain access to driveways.
There will be no work Thanksgiving Day, the week of the Christmas holiday nor on New Yearís Day.
Targeted end date for this project is 3/14/2013
