What should a surveyor do if they cannot find the original corner monument?

When a surveyor cannot find the original corner monument, verifying using record measurements and accessories is the proper course of action. This approach involves checking existing records, such as deeds or previous surveys, to establish the original location of the corner based on available evidence. Accessories include physical markers or reference points that might have been used in previous surveys, which can help reconstruct the precise location of the missing monument.

Conducting this verification ensures that the survey remains accurate and legally defensible. It is essential for maintaining consistency and reliability in land boundaries, which is a fundamental aspect of surveying practice. This method respects prior documentation and the integrity of the property lines, adding a layer of diligence to the survey process.

The other options, such as ignoring the issue or using only last known coordinates, would compromise the accuracy and legality of the survey results. Calling a specialist might be a prudent step in certain contexts, but relying on thorough verification with available records is the most practical and standard practice in surveying.
