Call Before You Dig

Call 811 Before You Dig

Dig Safely

Underground power lines and other utilities run under streets and sidewalks as well as under yards and homes. Accidentally digging into these lines could cause an electrical shock hazard and disrupt electrical service in the neighborhood. Damage to an underground power line could even result in electrocution.

Your utility locator center, reached by dialing 811, makes sure underground power lines and other utilities are clearly marked so people can dig a safe distance away from them.  Whether you are planning to do it yourself or hire a professional, call 811 at least 48 hours (two business days) before digging begins.  Any job requires a call, even planting a tree!

How 811 Works

When you call 811, you will be asked a number of questions about your planned digging project, including where it will occur and the starting date and time. 811 will notify all the major utilities that have underground lines near your digging area. The utilities will mark the location of each buried line so you can dig a safe distance away.

To give utilities time to mark their lines, you may dig no sooner than 48 hours after calling 811. If your work is delayed more than 30 days after calling 811, you must renew your request by calling 811 again.

After lines have been marked, make sure to respect the "tolerance zone," a safety area that spans 18 inches on either side of the marked underground line. Try not to dig within this zone—and if you must dig there, use hand tools only to protect buried utility lines from damage.
