  1. Owner/Operator Membership offers full service notification through Colorado 811. Locate requests are sent from Colorado 811 directly to your company or your contract utility locator via e-mail listing all contact information for person excavating, type of work, who the work is being done for, county, city, address or intersection of where they are requesting locates and a description of where the locates are needed.
  2. All phone calls into Colorado 811 are recorded and kept for 3 years, if call recordings are needed by Owner/Operator Member we will supply those if requested.
  3. All locate tickets are also kept for 3 years. If a copy of a ticket (within the last 3 years) is needed we will supply that at request.
  4. Appointment scheduling is available, but not mandatory, if an Owner/Operator member would like to offer that option. Appointment scheduling is at no additional charge.
  5. Owner/Operator membership requires a two year commitment, in accordance with state law.
  6. Positive Response is offered to Owner/Operator members. Positive response is a way to “Close” the ticket out by sending a response to the excavator through Colorado 811.
  7. A Ticket management system is offered to Owner/Operator members at no additional cost. The program is called WebTMS, used to receive your locate requests, assign them to a locator and close the ticket using positive response all through one application.
  8. During business hours we will give you a courtesy call on Damage Tickets.
  9. During after hours we will give you a courtesy call for Emergency Locates as well as Damage tickets.
  10. We offer an automated call out for our courtesy calls which you will receive as soon as the ticket is processed.


-An Automatic Positive Response Re-notification occurs when no positive response is posted by the Owner/Operator Member by the locate by date on the locate request. Colorado 811 will continue to send out re-notifications daily until a response is received by Colorado 811 or for 30 days from the locate by date, whichever comes first. Emergency and damage tickets will be excluded from these re-notifications at this time.

Member database is the responsibility of the facility owner. All changes to the database must be submitted in writing, to include mail, fax or e-mail to notify Colorado 811 Member Services of the requested change.

To better serve member needs, the following time line is recommended.

  • Member contact information updates will be accommodated in a timely manner with the resources and personnel available at the time of the request .
  • Database notification in tabular format should be submitted at least ten (10) business days prior to the time that notification would be needed for the geographic area submitted. From the date Colorado811 receives the update request, a total of three (3) business days are needed to complete the requested update into the existing database. The member facility will be informed when the update is complete, either by telephone or e-mail. Upon request, a revised database notification report can be obtained from Member Services.
  • Database notification in digital format (i.e. Shape Files) should be submitted at least ten (10) business days prior to the time that notification would be needed for the geographic area submitted. From the date Colorado811 receives the database update request, a total of five (5) business days are needed to complete the requested update into the existing database. The member will be informed when the update is complete, via e-mail. It’s the Members’ responsibility to view the update on-line. It is necessary for the member to establish a editing/viewing account with the assistance of Colorado811 personnel. Contact Member Services personnel for more information. A database validation form will need to be completed with each database update request submitted.
  • All digital data is processed through the Colorado811 GIS department. All requests for Shape Files of existing member facility notification database will require an e-mail sent to the GIS Department. Please allow ten (10) business days from the date of the request to complete this process.

In the Colorado One Call law it states that if you own or operate any underground facilities on or near a public right-of-way or easement you should be registered with Colorado 811.

This describes the required format of ESRI Shape files that can be imported into the Colorado 811 notification database.

The Shape file types supported are POINT, LINE and POLYGON. For POINT and LINE shape files, you must specify a buffer distance to apply to the file to create a polygon shape file. A buffer is a radius of a point and/or a line. Minimum buffer that can be applied to a point and line file is 30ft and the maximum is 1000ft.

Shape Files submitted should be packaged in a ZIP file and e-mailed, containing at least the following four (4) files:
(1) ESRI Shape (.SHP) File
(2) ESRI Shape (.SHX) Index File
(3) ESRI Shape (.DBF) Attributes File
(4) ESRI Shape (.PRJ) Coordinate System File
Along with the data please include the following information about the data.
(A) Sender Information – Who is supplying the shape file(s):
a. Name and contact information
(B) Member Code – The member code for which the notification areas will be applied to.
(C) Effective Date – The date at which the notification areas will become “effective”. You may specify that the notification areas be effective immediately or at some date in the future.
(D) Expiration Date – The date at which the notification areas will expire. You may specify that the notification areas expire NEVER or at some specific date in the future.
(E) Counties Covered – Which counties are covered by the submitted shape file. This can be a list of one or more counties, or you can specify the entire state (i.e., any counties the shapes fall into.)
(F) Buffer Distance (in FEET) – If the shape file being submitted contains point or line features, they will be buffered and converted into polygons. You must specify the buffer distance in feet for these types of shape files. Shape files containing polygons are assumed to already include the necessary buffers.
(1) When shape files are imported into the mapping database, they are automatically clipped to the county or counties they intersect.
(2) Polygons are limited to 4 square miles in area. Polygons that are larger than 4 square miles will be partitioned into smaller polygons that cover the same area.
(3) Polygons which are made up of more than 9 points will be simplified.
(4) There is a maximum density limit of 16 polygons per quarter minute grid.
