Five steps for safe digging:
Call 811 or request online two to three days before you plan to start your project.
Expect a response to your request in two to three business days. Affected utilities will mark underground lines.
Make sure all affected utilities have responded by comparing the markers to the list of utilities the 811 call center notified.
Use the markers as a guide for the duration of your project.
5) Dig Carefully
If you cannot avoid digging near the provided markers, consider moving your project.
