We only prune trees that pose a potential hazard to primary power lines. These are typically the highest (and sometimes also the second-highest) lines on a pole. We also prune trees and other vegetation to maintain EPB Fiber Optics lines, and the existing right-of-way. We prune all weak, damaged or dead limbs that hang above conductors. Pruning exceptions include low-growing trees (dogwoods, redbuds, ornamentals) and landscape quality trees less than 6 inches in diameter.
If you have a tree growing directly under power lines, we encourage you to let us remove it. We’ll cut the tree down, grind the smaller limbs, and cut the logs into fireplace lengths – all at no charge. As a property owner, you’re responsible for trees that interfere with service lines that run from a transformer pole to your home. But we’ll be happy to lower your service line to allow your tree contractor to prune and remove foliage, and then reinstall service at no charge.
A good rule of thumb is to look at the tree’s label to find its mature height, then plant it that same distance away from power lines and equipment. When you find the spot where you’d like to plant the tree, look up to see if there are any power lines or equipment overhead. And be sure to call 811 before you dig to ensure you don’t hit buried utility lines. An EPB Energy Pro can also offer advice on where, when and how to plant different varieties of trees and shrubs properly, and safely. If you’d like a free consultation with an EPB Energy Pro Arborist, please submit a request.
After you’ve found the spot where you’d like to plant, it’s best to do two simple things before you start digging. First, look up for any overhead power lines. You never want to plant directly under overhead power lines. And second, call 811 to find out if there are any utility lines buried underground. Both of these important steps could protect you from problems down the road.
Trees will be pruned a minimum clearance of 10 feet from power lines. Limbs may be pruned further from higher voltage lines. Limbs overhanging lines will be pruned as high as possible. We will also eliminate weak, diseased, and dead limbs above the wires that may fall or blow into the wires.
Do not plant climbing vines near power poles or guy wires, and do not plant shrubs or vines within 3’ to the side of, or 12’ in front of, ground-mounted transformer boxes.
Protecting a tree from becoming burned or entangled in power lines is actually for the health of the tree in the long run. This, of course, also helps prevent power outages caused by falling trees and branches. In addition, and most important, vines and trees touching lines can be hazardous. We always trim in ways that redirect new growth away from power lines. We trim only enough of a tree to prevent power lines and the public from being endangered. It's possible to prune a tree into various shapes when you prune correctly based on the tree's age and species, and a tree can remain healthy and safe for many years.
