Whether you are a homeowner planting a tree or a commercial utility contractor prepping a job site, it is always important to have all utilities marked before you complete any digging for a project. If you strike a utility line you could injure yourself or others working near you. You may also be liable for costs to restore service. As a way to help reduce utility strike accidents, the federal government implemented a national "Call before you dig" phone number - 811.
How does 811 work?
811 is a free call that should be made a few days before your digging project is set to begin. When you call 811 from anywhere in the country, your call will be routed to your local One Call center. A operator will ask you to provide the location of your project and will then contact the local utility companies to send out personnel to mark the utilities lines at the job site. It generally takes a few days for the lines to be marked. (Reminder: be sure to keep documentation such as dig permit numbers, dates of calls, dates utilities were marked, etc.)
