Vegetation Management

Ensuring safer, more reliable power while protecting and enhancing our urban forest

The Seattle area is known for its thriving urban forest. Trees are important to all of us - they provide shade, beautify properties and improve the health of our environment. Yet, trees are also one the main causes of power outages in our area, and can cause serious injuries or fatalities when they come into contact with utility equipment.

Every day, our Power Line Clearance team works to ensure the reliability of our electricity and safety of our communities and crews by employing a systematic approach to vegetation management around the utility’s complex network of substations, power lines and transformers.
