Project Description

Replace the failing direct burial primary electrical service with a new service installed as an underground raceway system. The new "raceway" system has underground pipes ("conduit") connecting to a series of concrete boxes ("vaults"). This "raceway" system allows access for repairs and meets the current code requirements for Seattle City Light.

The failing powerline runs underground around the outside walking path from south to north. The original intent of the project was to follow the same path for this replacement project, however, during the design phase sections of rock were discovered that would make the new raceway install much more complex. Seattle Parks and Recreation and Seattle City Light checked numerous locations within the park to reroute the electrical system and based on that work revised the design to route the new power system up the main road. This has allowed us to avoid many impacts to the natural areas and will enable future access to service and maintain the system.

During construction the contractor will need to close off sections of Seward Park roadway. Seattle Parks and Recreation and the contractor hired for the project will work to minimize impacts to park users and the community.
