The Land Surveyor has discretion regarding which of the following?

The choice of whether to sign, stamp, or seal preliminary documents is indeed within the land surveyor's discretion. Professional land surveyors are required to adhere to certain regulations and standards regarding the documentation they provide. However, the act of sealing or stamping documents typically indicates that the surveyor has reviewed the work and stands behind its accuracy and compliance with applicable laws, which includes local, state, and national standards. Preliminary documents often serve as drafts or proposals, and surveyors can decide whether to apply their official stamp or seal, based on the level of completeness and readiness of those documents for the client's or public's use.

In essence, this discretion allows the surveyor to differentiate between final certified documents and those that are still in development, ensuring that they only take responsibility for work that meets their professional standards.
