How far apart are marks for NJ One Call?

The correct answer is 25 feet, which is the mandated distance for marking the locations of underground utilities in New Jersey under the NJ One Call system. This distance is crucial because it helps ensure the safety and accuracy of identifying utility lines when excavation or construction work is being performed.

By marking utilities at this specific interval, workers can avoid damaging these lines, which could lead to dangerous situations, service interruptions, or costly repairs. The practice of marking utilities accurately and consistently contributes to the overall effectiveness of the NJ One Call system, which is designed to promote safe digging practices and protect both the public and infrastructure. Understanding this distance is essential for public works managers and anyone involved in excavation activities to adhere to legal requirements and promote safety on job sites.
