Seattle City Light plans to rebuild an existing vault at the intersection of 4th Avenue South and South Washington Street to increase electrical reliability. Crews will connect the vault with conduits (duct banks) to the existing electrical infrastructure along South Washington Street between 3rd and 4th Avenue. (See photos for Stage 1 and Stage 2
Crews will start by excavating at the intersection of 4th Avenue South and South Washington Street and then move onto the section between 4th Avenue and 3rd Avenue. After the new vault and duct banks are installed, the street will be restored.
What You Can Expect:
- No scheduled power outages
- Uniformed police officers will maintain traffic flow on all affected streets
- Pedestrian access will be available to all businesses at all times.
- All trenches will be plated at night.
- Impacts will be one section at a time. No parking will be impacted while crews are working at the intersection of 4th Avenue South and South Washington Street. Whereas, all parking spaces on the north side of Washington will be restricted during the time needed to work that section.
- The first three days of work at each section involve saw cutting the street and breaking concrete. After that, a backhoe will be used. Customers should expect noise during those times.
Once the civil construction is complete, crews will install new cable, which will take several days. This work will be less intrusive, involving up to two trucks and line workers pulling cable into place and working inside the underground vaults.
7/24/14 Update: City Light plans to work on Sunday, July 27 only this weekend. The approximate hours are 8 a.m. to 5 p.m.
Work is planned for weekends only while crews are at the intersection of 3rd Avenue South and South Washington Street. Once work starts between the intersections along South Washington Street, crews will work Monday through Friday, 9 a.m. to 3 p.m., with some weekend work possible.
