Tree selection and planting
When selecting a new tree to plant, EWEB recommends the "Right Tree, Right Place" approach.
Proper species selection and planting procedure can increase public safety, reduce power outages, reduce
the need for routine pruning and promote healthy, beautiful trees.
Under and next to electrical lines
Small trees (up to 25 feet in height at maturity) are ideal for planting under or next to overhead electrical
lines, and will seldom need to be pruned for electrical line clearance. The following trees are consider "line friendly,"
by EWEB and are suitable for planting under or next to overhead electrical lines.
- Beech, weeping purple
- Canada Red Chokecherry
- Cherry, flowering
- Columnar Spruce
- Dwarf Plum
- Galaxy Magnolia
- Globe Maple
- Golden Desert Ash
- Goldenchain Tree
- Hinoki Cypress
- Japanese Maple
- Japanese Snowball
- Royal Galaxy Magnolia
- Smoke Tree, purple
- Snowball Bush

- Weeping Spruce

tree selection guide.
Line adjacent portion of yard
Small to medium sized trees (up to 50 feet in height at maturity) are appropriate. Plant trees with spreading
crowns at least 25 feet away from electrical lines; plant trees with
columnar or pyramidal forms at least 15 feet away from electrical lines.
Non line adjacent portion of yard
Any size tree is appropriate. However, consider the size of the tree at maturity and proximity to buildings and other
public or private property. Proper tree selection can minimize potential hazards, and can help avoid costly
When landscaping or installing a fence -or other structure, keep in mind that
utility workers need clear access to pad-mounted
transformers for underground electrical lines. Please keep at least six feet clear in front
of the opening side of the transformer. In the event of a transformer failure that requires repair or replacement,
outages can be prolonged while crews remove landscaping or structures for access.
EWEB is required to maintain clearance around utility poles for maintenance and emergency access. Plant all perennial, woody vegetation
at least three feet from the utility poles for access, and to reduce the need for routine pruning.
Tree selection, location and proper planting technique are extremely important factors influencing the
long-term health of a tree. Please visit the International Society of Arboriculture
website for additional resources concerning tree planting.
