Earlier this year, Seattle City Light attempted to extend the useful life of the cable without having to replace it by injecting it with silicon. This process has worked well in more than 29 neighborhoods since we started the injection work four years ago. Regrettably, the cable in your area was not well-suited for injection and continues to experience unplanned outages. To remedy this situation, City Light crews will be performing emergency cable replacements to improve reliability. This work involves the installation of vaults and PVC conduits, which will be done by trenching. New cables will then be pulled into place to replace the outdated cables, which were installed in the 1970s. This replacement will improve electrical reliability in the neighborhood and help avoid future unplanned outages.
The boundaries for this project are approximately NW 117th Street on the north, NW 112th Street on the south, 3rd Avenue NW on the east, and Carkeek Park on the west. Work will begin near the intersection of NW 117th Street and 3rd Avenue NW and proceed down NW 116th Street.
Power outages will need to be scheduled to perform this work. Residents will be advised at least 48 hours in advance of any outages. A door hanger will be left on affected homes to let residents know the specific date when the outage will occur. A minimum of two outages are expected during the cable replacement project. The outages are necessary to do our work safely and efficiently and typically will last between 8-10 hours.
The work will involve trenching to place the conduit and vaults. Street restoration will be directed by the Seattle Department of Transportation. Traffic restrictions will be minimal and signage will be used to keep residents informed.
6/18/2013 Update: Civil construction is complete. A small amount of cable will need to be pulled to complete the work.
