What term refers to the marks that indicate the outer edges of the shoulders in a surveying context?

In surveying, the term that refers to the marks indicating the outer edges of the shoulders is known as "shoulder stake." These stakes are specifically placed to identify the boundary lines of the road shoulders, ensuring that proper alignment and grading are maintained during construction. They serve as reference points for workers to establish the cross-section of the road and help in maintaining the design specifications for the roadway.

The other terms listed relate to different aspects of surveying and construction. For example, slope stakes are used to mark the slope of embankments, while offset stakes are set at a distance from the centerline of construction to help guide the alignment of the project. Finish grade stakes indicate the final elevation of the ground surface, which is different from the function of shoulder stakes.
