What should the original map be carefully preserved with?

The correct choice is preserving the Land Surveyor's original documents alongside the original map. This is crucial because original documents provide the foundational data, assumptions, methodologies, and legal boundaries that were used to create the survey map. These documents serve as vital evidence of the survey's validity, methodology, and compliance with applicable standards and regulations.

Original documents may include field notes, calculations, or other technical records that help in understanding the survey's context, ensuring that any future reference or verification can be accurately performed. Keeping these documents with the map allows for a comprehensive understanding of the survey details, facilitates updates or corrections if necessary, and supports legal claims regarding property boundaries.

In contrast, client testimonials and maps from previous projects may not provide the necessary technical information needed to substantiate the original survey work and could vary greatly in relevance or reliability.
