Property owners are required to have underground utilities located before doing any digging, even for small projects like planting trees and shrubs.

Why Locate?

The depth of utility lines varies and there may be multiple utility lines in a common area. Damaging a utility can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs.

Locate an Underground Utility

Before You Dig

  • Call 811 a few days prior to digging, and your call will be routed to your local One Call Center.
  • Tell the operator where you're planning to dig, what type of work you will be doing and your affected local utilities.

What Happens Next?

  • The City of Boulder Public Works Department and other utility companies will be notified about your intent to dig.
  • Within a few days, a locator will mark the approximate location of your underground lines, pipes and cables, so you'll know what's below - and be able to dig safely.
