The licensed land surveyor or registered civil engineer filing the record of survey shall attempt to reach agreement with the county surveyor regarding the language for the explanation of the differences. If they cannot agree on the language explaining the differences, then both shall add a notation on the record of survey explaining the differences. The explanation of the differences shall be sufficiently specific to identify the factual basis for the difference.
