Frequently Asked Questions about 811 and Safe Digging

En Español

Q: Who should call 811?

A: ANYONE, including homeowners and excavators, planning to dig or alter the surface of the ground.  So whether you’re a do-it-yourselfer planning a weekend project or a professional excavator, one phone call to 811 will get your underground utility lines marked.

Q: How far in advance do I need to call?

A: After you call, wait 48 hours, beginning 7:00 a.m. the next working day (Working days exclude Saturdays, Sundays, and legal state and national holidays) following notice, to allow the utilities to mark their facilities.

Q: My yard is marked, now what?

A:  Protect and preserve the markings from the time the excavation begins until markings are no longer required for proper and safe excavation near the utility lines.  Excavate carefully!  Virginia law requires hand digging within 24 inches of a marked utility line.

A: NO.
  Please call only if you intend to dig.
