Why did you trim so much of my tree?

Faster growing trees will require more clearance than slower growing trees. Smaller, slower growing trees will require less trimming and are more suitable to be planted closer to electric lines. Umatilla Electric Cooperative takes into consideration what type of species the tree is, how fast the tree will grow, how close it is to the electric lines, and the type of voltage running through those lines. The required distance between vegetation and power lines varies from line to line depending on the voltage, local ordinances, tree characteristics, and the tree owner.
