The boundary of the subdivision shall be designated by a border of prussian blue water color approximately 1/8-inch wide applied to the reverse side of the tracing inside such boundary lines. Such water color shall be of such density as to be transferred to a blue-line print of said map and not obliterate any line, figure or other data appearing thereon. All lines shown on the map which do not constitute a part of the subdivision itself shall be clearly distinguishable from those lines which are a part of the subdivision, and any area enclosed by such lines shall be labeled “not a part of this subdivision.” The map shall show the definite location of the subdivision and particularly its relation to surrounding surveys.
