Seattle City Light & Occidental Avenue Alley: A Milestone

Seattle City Light has made great strides in upgrading the electrical reliability of Pioneer Square and improving the looks of Occidental Avenue Alley. City Light crews excavated and replaced aging underground duct banks in the alley just east of Occidental Park earlier this year. In June, a contractor helped the project reach a milestone by restoring the alley with Pioneer Square Preservation Board-approved brick. When complete, the project will not only help increase the reliability and capacity of Pioneer Square; but also, the downtown electrical system.

Restoration of Occidental Alley
Occidental Alley

City Light has now partnered with the Pioneer Square Preservation Board in restoring three alleys with brick since 2016, in keeping with the history of the area. The other alleys, Pioneer Passage and Nord Alley, are just east of 1st Avenue between South Jackson Street and Yesler Way.

Construction at Occidental Alley
Trenching and new conduit installation in an earlier phase of the project.

Crews from City Light and the contractor made these updates while working to minimize impacts to the surrounding community.  City Light appreciates the patience of our customers along the alley during this construction.

The final phase of the project will have electrical crews pull in a last section of cable through the new conduit. These improvements will last for years to come while keeping the historical features of our city intact.
