What is the requirement for setting monuments according to an RPLS?

Setting monuments according to a Registered Professional Land Surveyor (RPLS) involves ensuring their stability and longevity, which is why the requirement that all monuments shall be set at a sufficient depth for stability is essential. This depth is crucial to prevent movement due to environmental factors such as soil shifting, frost heave, or erosion, which can occur with changes in temperature and moisture levels. A properly placed monument provides a reliable reference point that can be consistently located over time, which is vital for future surveys and land boundary determinations.

Monuments that are not set deeply enough may be easily displaced or damaged, leading to inaccuracies in surveying. Therefore, stability achieved through proper depth placement is fundamental to maintaining the integrity of the monument and ensuring accurate and reliable survey results over the long term.
