Call Before You Dig
It's safe. It's free. It’s the law.

By law, homeowners or contractors planning projects involving digging must call 811 at least 48 hours in advance. Free of charge, the notification center will alert utilities such as electric, gas, cable and phone companies so they can mark the location of their underground lines.

Following these simple steps can prevent an interruption of service or potential safety hazard:

  • Call 811 before you dig  
  • Wait the required amount of time (at least 48 hours)
  • Respect the locator's marks  
  • Dig with care
