You are always required to call or notify Colorado 811 when any excavation occurs on your property. You have started the notification process. When you complete your request using iDig811, a notice is sent to utility owners who have gas, electric, cable TV, phone or other lines near your property.

You may have some utility lines inside of your property boundaries and those lines are called “private lines” or “private facilities”. You are responsible for being sure that the lines inside of your property boundaries are properly marked before excavation starts. Some of the utility companies Colorado 811 will notify regarding your pending excavation consider lines within your property boundaries to be “private utilities” and they will communicate that to you but only after you have completed your Colorado 811 form. Utility lines  on your property such as propane lines to fire pits or grills are also considered private utilities and will not be marked by a utility company.

Do not use the services of a private locate company until you have submitted a request through Colorado 811 and have received confirmation that a ticket or notice of pending excavation has been generated by Colorado 811. You will receive a confirmation directly from Colorado 811.

There are companies who will mark the utility lines inside of your property boundaries but they do charge a fee for that service. Please CLICK HERE for a list of private locate companies. The failure to mark lines inside of your property boundaries and the cutting or damage to those lines can result in serious personal injury or death. You will be responsible for any damage to any lines on your property regardless of who marks the lines.

The area to be marked must be completely accessible, free of locked gates and animals for three (3) business days from the date the email confirmation is received.

If your location could not be confirmed in our database. Please attempt your request with the correct street name and suffix. If the error continues, please contact Colorado 811 at ticket@co811.org to complete the processing of your request.
