PRE-MARKING YOUR PROJECT
State law requires excavators to white-line the dig site when practical.
White-lining is the process of marking the dig area with white paint and/or white flags prior to contacting JULIE. In winter months, black paint or flags should be used when snow is present.
White-lining allows utility locators to complete their work more quickly and makes it easier for excavation crews to identify the dig site. It can also reduce the number of joint meets needed.
- Use only white paint and/or flags (black when snow is present)
- White-line your project prior to contacting JULIE
- Paint with dashes, lines or arrows
- The width of each mark should be approximately 2"
- The length of each mark should be 6" to 12"
- The distance between marks depends on site conditions, but should be no greater than 20'
- Company identification should be painted at reasonable intervals to allow for quick identification
- Pre-marks that box in the excavation are limited to that box (unless specified otherwise on the locate request
- Mark the center line
- Indicate on your locate request that you want locators to mark at least 10 feet past your white-lined area
For additional information, or if you have any questions, please contact a Damage Prevention Manager in your area.
SINGLE STAKE PRE-MARKINGS CENTER POINT OF EXCAVATION SITE
When an excavation site is contained within a 50’ radius or less, it can be delineated with a single stake that is positioned at the proposed center of the excavation. If the excavator chooses this type of delineation, they must convey that they have delineated the excavation site with a single stake at the center of the excavation and include the radius of the site in the notification to JULIE. This single stake is to be white in color with the following information: excavator’s company identifier (name, abbreviations, or initials) and the radius of the excavation site in black letters on the stake or with a notice attached to the stake.
TRENCHING, BORING OR OTHER CONTINUOUS TYPE EXCAVATIONS
Pre-mark in white paint the proposed centerline of planned excavation using 6” to 12” x 2” arrows, approximately 4’ to 20’ apart to show direction of excavation. The maximum separation of excavation pre-marks would be determined by site conditions but should never exceed 20’. Pre-mark lateral excavations with occasional arrows showing excavation direction from centerline with pre-marks at curb or property line if crossed.
NON-LINEAR EXCAVATION PRE-MARKINGS
Delineate in white the proposed area of excavation through the use of: a continuous line, dashes marking the four corners of the project or dashes outlining the excavation project. In lieu of paint, stakes, flags or whiskers, may be used. Limit the size of each dash to approximately 6” to 12” in length and 2” in width with interval spacing approximately 4’ to 20’ apart. The maximum separation of excavation pre-marks is to be reduced to a length that can be reasonably seen by the underground line owner’s locators when the terrain or excavation site conditions warrant it. Stakes, flags or whiskers are white in color with the excavator’s company identifier (name, abbreviations, or initials) provided on the stake, flag or whisker.
