Planting around electrical equipment
When deciding where to plant trees in your yard be certain to consider overhead and underground utilities and plan your landscaping accordingly. Inappropriately placed large trees can damage sidewalks and curbs, in addition to phone, water, sewer and electric lines. They also can affect traffic visibility.
In addition to the information on our site, you'll find more good advice on the International Society of Arboriculture website.

Putting up a fence? Planting a tree? Installing irrigation lines?
In many subdivisions power lines along with other utilities are underground. To avoid possible injury to yourself or damage to the lines please let us locate them for you before you start digging.
This is a FREE service.
Call 811 or 1-800-553-4344 at least two working days before you plan to dig, and all affected utilities will send workers to mark each underground line with color-coded paint.
