Safety: Call Before You Dig

If you're planning to do any outdoor work that involves digging, such as landscaping, installing a fence or building a deck, be sure to call before you dig.

Just dial the number below for your state at least three days before you start, and the area "one-call" office will send a utility worker to mark the location of underground lines on your property.

Digging

If your state isn't listed, try the Nationwide One-Call Directory.

When you start digging, try to stay at least 24 inches away from the marked lines. If you're planting a tree, remember to consider the length of the roots as the tree matures, and don't plant larger trees under power lines.

The chart below shows the color-coding used on the marker flags:
