Utilities & Easements
Evaluating Utilities & Easements for Tree Planting
Planting a tree without a plan that takes into account presence of utilities and easements can lead to more problems than benefits. Stopping to evaluate and develop a plan for tree planting can save you from interference with utilities and other infrastructure, increased time or financial investment on landscape maintenance, or even personal injury and property damage.
Before taking any steps to plant a tree, find out where your utilities are located. The utilities of greatest concern include overhead utilities and underground utilities.
Overhead Utility Lines Overhead utility lines include electric, phone, and cable. Trees that are planted to close to an overhead utility line could require pruning to maintain a safe distance between branches and the wires. Planting the right tree in the right place can prevent the need for this practice.
Planting Distance From Overhead Lines
Mature tree size influences how close a tree should be planted to an overhead line:
- Large trees should be planted at least 45 feet from an overhead line.
- Medium trees should be 35 feet from an overhead line.
- Small trees should be 15 feet from an overhead line, unless they will be less than 20 feet tall at their mature height.
- Trees with a mature height less than 20 feet are “utility compatible” and may be planted underneath overhead lines.
Underground Utility Lines
Underground utility lines Include service wires such as electric, cable, and phone, as well as gas lines, water lines, sanitary sewer, and other public infrastructure. Contact Call-OKIEto locate underground lines and plant your tree at least five feet from any located utilities.
Planting Complications with Underground LinesPlanting too close to an underground utility could lead to:
- Damage to the utility and personal liability
- Future damage to or removal of your tree during utility maintenance
- Personal injury
Also be sure to locate any private easements on your property plat. Even if a utility does not currently have infrastructure within a platted easement, there is a possibility that one day it will. It’s best to avoid planting trees within easements in order to avoid removal of a healthy tree in the future.
