If you are planning to dig on your property, notify your local one-call center by calling "811"2 to 3 days before you plan to dig. The one-call center will transmit information to affected utility operators. Wait 2 to 3 days for affected utility operators to respond to your request. On average, between 7-8 utility operators are notified for each request. Confirm that all affected utilities have responded to your request by comparing the marks to the list of utilities the one-call center notified.
Respect the Marks
The marks provided by the affected utility operators are your guide for the duration of your project. If you are unable to maintain the marks during your project, or the project will continue past your request’s expiration date (varies by state), please call 811 to ask for a re-mark.
Keep in mind, hand digging is required within two feet either side of the utility markings.
