You've trimmed my trees before, but you've never done THAT!


City Light pays close attention to what our customers are saying to us and about us, and lately we've received a number of concerned emails and phone calls about the degree to which we're trimming trees in our service area.

We're always willing to come out and speak with concerned customers about our line clearance operations, but we need to hear from you before the work begins to avoid disappointment, anger and/or frustration after the fact. City Light hangs door-hanger notification cards at EVERY PROPERTY where we intend to work.

As soon as you see that door-hanger, if you have any questions or concerns about how we're going to trim your tree, contact us immediately. Call the number on the door-hanger, or email us your name, address and the Feeder and Site number on the door-hanger to sclvegetation@seattle.gov

There is a lot of planning, training and resources that go into the line clearance program and we'd like to take a moment to share with you some changes that have been made within the last few years and how they've influenced the work we do. To find out more, CLICK HERE.



Protecting Our Lines, Respecting Our Environment


Everyone at Seattle City Light is committed to producing and delivering environmentally responsible, safe, low cost and reliable power - Vegetation Management is no exception.

It's no easy task; with over 1,700 miles of lines running through eight cities and Unincorporated King County, and 657 miles of transmission right-of-way spread across five counties, we have hundreds of thousands of trees, shrubs, vines, and landscapes to maintain. With a small core of dedicated utility vegetation management professionals and a network of highly trained, qualified contractors we work year-round to find solutions to these ever-growing challenges.

The utility vegetation management industry is evolving and City Light is growing with it. In the last 25 years advances in arboriculture - the study of trees, shrubs and vines - have unlocked a deeper understanding of how woody plants respond to pruning and injury.

Come explore our programs - find out more about who we are, what we do, how and why. Learn about the challenges and opportunities Vegetation Management faces as the demands for reliable, safe energy and our urban forests continue to grow.


Vegetation Management

The Distribution Tree Trimming Program maintains and monitors over 300,000 trees with the potential to grow/fall into our power lines and critical infrastructure. We work along 1,770 miles of overhead lines in Seattle and parts of Burien, Lake Forest Park, Normandy Park, Renton, SeaTac, Shoreline, Tukwila and Unincorporated King County.

The Urban Tree Replacement Program (UTRP) mitigates for City Light's impacts on the urban forest through outreach and education, neighborhood tree planting projects and by replacing the trees we remove with species suitable for overhead lines.

The Transmission Right of Way Maintenance Program manages vegetation along 657 miles of transmission right-of-way through King, Snohomish, Skagit, Whatcom and Pend Oreille counties. This includes environmental impact mitigation and monitoring when necessary.

The Landscapes Maintenance Program maintains and improves the landscapes in and around substations, service centers and other SCL facilities and restores customer-owned landscapes impacted by City Light.


Protecting Yourself - Safety Tips


Seattle City Light does not allow anyone within 10 feet of our distribution or 17 feet of our transmission lines unless they are properly credentialed. This is for the public's safety as all power lines can carry potentially fatal energy loads at any time. Always follow these Safety Tips and contact City Light if you have any questions.
  • Never climb trees or fly kites or any other objects near power lines.
  • Never build or play in a tree house if there are power lines near the tree.
  • No one other than Seattle City Light employees or its qualified contractors should ever come within 10 feet of a line or 17 feet of a transmission line.
  • If you see a potentially dangerous situation with trees and power lines such as arcing or sparking wires, immediately call (206) 386-1733
