What should be noted if the Land Surveyor has knowledge of any unobservable easements at the time of the survey?

In the context of land surveying, when a land surveyor is aware of unobservable easements, the appropriate course of action is to note a lack of observable evidence. This is significant because it highlights that, while the surveyor may have information regarding the existence of certain easements, these cannot be directly verified or examined during the survey process due to their unobservable nature.

Documenting a lack of observable evidence is crucial for transparency and accuracy in the survey report. It informs all stakeholders that while there may be known easements that affect the property, they cannot be visually confirmed on-site, which is important for liability and due diligence purposes. This distinction helps prevent misunderstandings or disputes about property rights and land use in the future as it clarifies the limitations of the survey.

The other options propose ideas that do not accurately address the fundamental principle of professional surveying practice regarding the treatment of unobservable easements. They either mislead about the necessity of visualization or incorrectly imply that surveying these easements will be deferred or omitted completely. Therefore, noting the lack of observable evidence is key to maintaining integrity and accuracy in the surveying process.
