What distinguishes a bench mark from a property corner?

The distinguishing feature of a bench mark is that it specifically indicates elevation, providing a reference point for altitudes relative to sea level or other datum planes. This is crucial for construction, land development, and topographical mapping, as it allows surveyors to determine the height of points in relation to this reference. In contrast, a property corner is established to demarcate the boundaries of a parcel of land, ensuring that property lines are clearly identified for ownership and legal purposes.

Understanding this distinction is important because it highlights the different roles that these markers play in surveying and land management. Bench marks help in understanding topography and drainage, while property corners ensure that land ownership is accurately represented and respected.
