Work planned on: View Ridge Conduit Installation

Project Overview
Underground electric cable in View Ridge was buried directly in the ground from 1969 to 1974 using the technology and materials available at the time. As underground cables age, the protective insulation deteriorates. In 2009 and 2010, Seattle City Light tested and, where possible, injected the cable with silicon. The silicon injection process extends the life of the cable by at least 20 years. Approximately 60 percent of the cable that was tested was injected. The other 40 percent of the cable in the neighborhood was tested but found not suitable for injection. That 40 percent must now be replaced. The next step in replacement is installation of conduit. Seattle City Light is hiring a contractor to install conduit and associated work, including new electrical vaults; curb ramp installation and restoration, sidewalks, pavement, and landscaping. The final step will be pulling the cable into the protective conduit by Seattle City Light crews.

Project Update
In 2012, test holes were drilled to determine the location of other utilities that are near where the conduit will be installed. The conduit will be installed by tunneling beneath the ground's surface. This method is called horizontal-directional drilling (HDD). HDD is much less disruptive to sidewalks and landscaping than open trenching. It is also a less expensive, faster means of replacing the electrical system. City Light's Resident Engineer will be on-site to monitor the contractor.

The status of your electric cable may have changed due to the need to make emergency repairs since the original silicon injection project. A map showing the locations where new conduit and vault installations are necessary and a construction schedule by area can be found here.

8/4/2014 Update

All segments north of NE 65th should be completely finished by September. The start date for those segments south of NE 65th Street is planned for 3rd quarter of 2014.
