From pools to planting, before you begin any kind of digging project, it pays to know where underground utility lines are buried. Because natural gas, electric, water, and telephone lines run beneath the surface of streets, alleys, landscaped, or vacant land, they can be hit and damaged by digging tools.

To prevent unnecessary damage to utility lines, the law requires you to call before you dig. Within two working days of your call, the utility lines will be marked so you or your contractor can dig safely. Failure to obtain the proper location of underground utilities is a violation of the law and could result in significant fines or repair bills.
