City Light Plans Work to Increase Reliability on Summit Avenue East

Seattle City Light is working to increase the reliability of the electrical system in the Capitol Hill neighborhood by installing new conduit (duct bank) and electrical vaults along Summit Avenue East and East John Street, adjacent to Summit Slope Park.  

The work will be completed in three stages, beginning with Stage 1. Orange highlights indicate the construction work areas.

  • Stage 1 (Early to late September): A vault shoring box will be assembled on Summit Avenue East. Two days are required for the assembly and disassembly of the box. A portion of East John Street (between the driveways on the east and west side of the Starbucks parking lot) will be closed to traffic due to the vault installation. Vehicles will have access to the parking lot on the south side of East John Street. Vehicles exiting the lot onto East John Street will be required to turn left.
  • Stage 2 (Late September to October): The alley next to Summit Slope Park will be closed during work hours.
  • Stage 3 (From October to November): A portion of East John Street (on the west side of the Starbucks parking lot) will be closed to traffic due to the duct bank installation.

Customers can expect sidewalk and traffic restrictions around Summit Slope Park. Traffic and pedestrian safety will be maintained by uniformed police officers. Travel lanes on Summit Avenue East will be maintained in both directions.

Daily work hours are from Mondays through Fridays, 9 a.m. to 3 p.m, and Saturdays from 8 a.m. to 4 p.m.
