The Nation’s Greenest Utility

Greens Seattle Neighborhoods

Since 2012, Seattle City Light's Urban Tree Replacement Program has planted over 900 trees in Seattle's transportation right-of-way (planting strips) in: Beacon Hill, Columbia City, Green Lake, Rainier Beach, West Seattle, and, most recently, Pigeon Point. The trees are staked and mulched when planted and will be watered for three summers to help them survive and thrive. In addition to greening our city, the small stature trees planted under power lines reduce the need for future power line clearance tree pruning. This spring, Seattle City Light partnered with Seattle Department of Transportation (SDOT) to plant the trees in Pigeon Point and replace dead trees in the Beacon Hill median.

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 657 miles of high voltage transmission power lines spread across five counties and over 1,700 miles of distribution power lines running through eight cities and unincorporated King County 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.

Seattle City Light has been designated by the National Arbor Day Foundation as a Tree Line USA utility since 2013 in recognition of the utility's quality tree care programs and services.
