Whether you are planning to do it yourself or hire a professional, smart digging means calling 811 before each job. Homeowners often make risky assumptions about whether they should get their utility lines marked, but every digging job requires a call – even small projects like planting trees and shrubs.

Why should I call 811 before every dig?
The depth of utility lines varies and there may be multiple utility lines in a common area. Digging without calling can disrupt service to an entire neighborhood, harm you and those around you, and potentially result in fines and repair costs. Calling 811 before every digging job gets your underground utility lines marked for free and helps prevent undesired consequences. Professional locators will mark the approximate location of the buried facilities with paint or flags.
Can I submit my request to have my utility lines marked online at this web site?
No. Please call 811 directly. Your local One Call Center will advise you of online services available to submit locate requests. For additional local information, click here.
I’m just a homeowner, not a contractor—is 811 for me?
