What Utility Flags and Paint Do—and Do Not—Tell You
Treat locate marks as part of the digging process, not a complete underground map.
Utility marks help communicate information about buried facilities within a planned work area. They are an important part of excavation preparation, but they do not tell the whole story by themselves. A marked route should not be treated as proof of a line's exact depth, and the absence of a mark should not be treated as a guarantee that the ground is clear.
Before digging, follow the state's 811 process and confirm the required utility responses. Discuss private lines separately where they may be present. The people responsible for excavation also need to follow the applicable requirements for working around marked facilities. A colored line on the lawn is a starting point for that process, not permission to guess around the service.
Leave active flags and paint undisturbed. If marks fade, are removed, or conflict with site information, contact the appropriate locating service or utility through the required process before affected work proceeds. Changes to the planned work area may also require the locating arrangements to be reviewed.
Remember that a photo of yesterday's marks is useful documentation, not a replacement for visible, current information and the required process. Weather, site activity, and a change in work limits can affect what needs to happen next. If you are unsure whether the marking arrangements still apply, ask before the affected work proceeds. The point is to resolve uncertainty through the responsible service, not interpret an old picture as a complete excavation plan.
Property owners can help by explaining the intended project clearly and keeping access available for locating. Call J&L Underground Construction at (417) 456-0551 to discuss private locating and excavation planning. The useful question is not only “Where are the marks?” but also “Have the services and work limits for this project been properly addressed?”
