Call before you dig
It's fast, it's free, it's the law.
Washington and Oregon laws require persons doing any type of excavation
to Call Before You Dig. The law covers both public and private property.
Excavating includes any movement of rocks, soil, or other material on
or below ground. You must call at least two business days before you
dig. After calling, you must wait two business days before digging so
that utility employees have time to complete your request.
Get more information on your local One Call Center, or make an online request for utilities to be marked (where available).
Select the state in which you will be digging, and enter your e-mail address, further instructions and login information will be e-mailed to you.
Request the utility location services. First-time visitors will need to register. Register and choose the state in which you will be digging.
What the markers mean
Utility employees will mark the ground with colored paint, stakes, or flags. The marks show the location and path of the utility. The colors of the markings mean the following utilities are underground:
When digging within two feet of the marked area, only use small hand tools, such as a garden trowel, to carefully expose the utility line. Keep in mind that utility installation is not the same for all utilities and requirements have changed through the years. Not all utilities are installed with protective casings and can be vulnerable to damage by tools as simple as a shovel. Always proceed with caution when digging around utility lines.
