Which of the following is NOT a criterion for calling in a Watch and Protect?

The correct answer is based on the criteria for calling in a Watch and Protect, which is typically focused on the presence of critical structures in proximity to the worksite. The purpose of a Watch and Protect is to ensure the safety of critical infrastructure during excavation activities.

Critical structures, which may include buildings, pipelines, or utility lines, are critical to consider when determining the need for extra precautions. In this scenario, options stating distances concerning critical structures—including those within 100 feet of the dig extent, across the street, or within the intersection—are all valid criteria for raising a Watch and Protect due to their potential for impact during excavation.

In contrast, "No surrounding vegetation" does not directly relate to the proximity or potential threat of critical structures. Vegetation might affect the work environment, but it does not constitute a criterion for requiring enhanced monitoring or protective measures in the same way that critical structures do. Thus, this option stands out as the one that is not applicable in the context of determining whether a Watch and Protect should be called.
