Low Impact Marking

Whether requesting a new locate ticket or renewing an existing ticket, excavators are required to follow low impact marking practices. This begins with the locate description on your ticket. The practices outlined below serve four purposes:

  1. Helps ensure the locate is accurate
  2. Reduces unnecessary locate marks
  3. Reduces the amount of time locate marks are refreshed
  4. Reduces time for the locator

Ticket size

One ticket can cover a linear distance of up to one mile on a street and up to 150 feet in either direction along crossing streets that are identified in the ticket.

One ticket can include up to five individual addresses as long as the linear distance from the first address to the last is one mile or less.

One locate ticket may cover an area of undeveloped land of no more than one square mile. The  boundaries of the work area MUST be described on the ticket. This ticket may also include work on any single street or right-of-way bordering the area of undeveloped land. Work on an additional bordering street or right-of-way requires a separate ticket.

Ticket requests

Locate tickets should cover only those portions of a work site where digging will occur within 30 calendar days of the date the ticket is requested. Know the job site and give an accurate description of where it is located. Addresses, street intersections, railroad tracks, references to natural landmarks and driving directions are helpful.

Ticket renewals

When renewing tickets for jobs lasting longer than 30 calendar days, delete any areas where excavation is finished. Make sure that your office staff calls the field contact to confirm whether the locate ticket should be renewed and clarify what portion of the work site is incomplete.  ***IMPORTANT*** If your office staff renews tickets, let them know when an ongoing project is complete so that tickets are not continually requested for that job.

 

White lining

Work sites that are difficult to describe should be pre-marked (white lined) if the excavator and member have not mutually agreed otherwise. See examples below.

If working in a few small areas along a mile of roadway, white line those areas.

If you're installing a fence that doesn't enclose the entire yard (as above), don't ask for the entire yard to be located. Instead, narrow like this, "locate north property line from front to back of house and perpendicular to the house."

Other helpful tips

  • Tell exactly where on the job site the digging will occur and how deep it will be.
  • Note any special conditions that may interfere with the locator doing his job such as a gated community, locked fences or a vicious dog.
  • If digging in one corner of an intersection, don't have the ticket cover an entire block. For example, you could specify that you're digging in the northeast corner or use a landmark to identify the corner.
  • Acceptable marking products for pre-marking a proposed excavation in white or marking underground facilities: flags, stakes, temporary/non-permanent paint, other industry accepted low-impact marking practices. Members are required to mark their underground facilities in appropriately designated colors.
