Before you start digging to plant a tree, install a fence or any other landscaping activity, call to have the underground utility lines marked. The number is 811. Call it before you dig to have your underground utility lines marked—for free. We recommend calling before starting any project that requires digging, even small projects like planting shrubs. Hitting an underground utility line with your shovel can knock out power to your house or neighborhood, and it can cause serious bodily harm—even death—not to mention a rather large bill from the utility company.
When you call 811 from anywhere in the country, your call is routed to affected utility companies, which send out a professional locator to mark the underground lines, usually within a few days. For more information, visit call811.com.
