How Will the Trees Look When Pruned?The trees will be trimmed according to where the electric lines are located. Some examples of how trees may be trimmed are below.
How Are Trees Pruned?The City prunes trees based on a technique called "directional pruning." This technique was developed by the National Arborist Association, approved by the American National Standards Institute, and adopted by the pruning industry as the standard. The city also uses Dr. Alex Shigo's guide, Pruning Trees near Electric Utility Lines as a reference.
With directional pruning, entire limbs or portions of limbs growing toward the lines are removed at the main branch or trunk. They are removed at a point where they would naturally shed if they had cause. By doing this, future growth will be directed away from the wires, and rapidly growing attached sprouts will be minimized. The city follows a pattern of trimming known as circuit trimming. This means the trees are trimmed along an electric circuit. Trimming is also done in "hot spots." This is when there is a limb laying or rubbing against an electric line and causing problems. Rocky Mount trim's trees on a five year schedule.
Determining Planting LocationDetermining where to plant a tree is a decision that should not be taken lightly. Many factors should be considered prior to planting. When planning what type of tree to plant, remember to look up and look down to determine where the tree will be located in relation to overhead and underground utility lines. Trees that grow no taller than twenty-five feet and planted outside fifteen feet on either side of the poles is the proper distance. Small trees that can be planted near power lines include dogwoods, redbuds, crepe myrtles, and holly.
Planting Near and Around TransformersAny obstructions, defined as fencing, shrubs, trees, vines, flowers, and any other materials or objects placed around the underground transformer by residents, which hinder the ability of the City to adequately and safely service, repair or inspect the transformer is prohibited. Fencing, shrubbery, etc. is allowed in accordance with the following guidelines:
- The front of the transformer must be free of any obstructing material so that it is clearly visible.
- Plantings or fencing may be placed around two sides and the back provided that a 5' clearance must be maintained. Trees planted within 15' of the transformer may eventually require removal if tree roots or foliage hinder service or maintenance of the transformer.
- The top of the transformer must be completely unobstructed.
- Any shrubs or bushes planted must not be of a variety which bear thorns or sharp protrusions of any kind or any variety of running vine, i.e. ivy which will grow over the transformer.
- Contacting the Electric Division of the City of Rocky Mount before planting is encouraged.
- Obstructions found by repair or inspection crews will be removed without notice to the resident.
