Project Details

French Creek Transmission Poles

Posting Date: 6/6/2016                

Contact: Kee Leung - Sr.,Electrical Engineering Specialist

Phone: 206-684-3082


Crews have erected the four new mono steel poles and removed/salvaged a total of five old lattice towers.  They have transferred new sets of power lines along the new poles. Equipment installation will continue through 9/14/17 and the project should be completed with the construction area restored by approximately 11/30/2017.


Seattle City Light will construct four electric transmission poles along French Creek west of the intersection of 363rd Avenue NE and SR 530 east of Arlington. The creek is eroding its bank near two steel towers, jeopardizing their stability. The new poles are needed to maintain regional electrical reliability. Seattle City Light will relocate and replace two towers with steel poles, remove one existing steel tower entirely, and construct two additional steel poles for a total of four new poles. See the map for the tower/pole arrangements. Contractors will improve access roads so that equipment can be transported to the site, then build pads and piers for the placement of the new poles. City Light will erect the poles and transfer the power lines over two seasons. This phasing is necessary to maintain electrical service.
