How should an RPLS set monuments?

Setting monuments is a crucial aspect of land surveying, and the method used should prioritize both stability and visibility. When an RPLS (Registered Professional Land Surveyor) sets monuments, they should do so at a sufficient depth for stability and distinction. This approach ensures that the monuments will remain in place over time despite environmental factors such as erosion, ground movement, or changes in landscaping.

By embedding monuments at an appropriate depth, the surveyor protects them from being easily disturbed or displaced, which is vital for the integrity of boundary demarcations. Additionally, the monument must be distinct enough to be identified later, which is critical for verifying property lines during future surveys or disputes.

While the other choices present various considerations, they lack the critical elements of stability and enduring visibility that are essential in monument placement. Monuments that are above ground might be visible, but they risk being damaged or removed. Random placement does not adhere to any systematic approach and could lead to confusion or dispute over boundary lines. Lastly, limiting monuments to just the corners of the property neglects the need for adequate referencing along the entire boundary, which is necessary for comprehensive surveying.
