Prior to the approval of the final plat, permanent reference points shall have been placed in accordance with the following requirements.
(A) Subdivision corner tie. At least one corner of the subdivision shall be designated by course and distance (tie) from a readily discernible reference marker. If a corner is within 2,000 feet of a U.S. Coast and Geodetic Station of N.C. Grid System coordinated monument, then this corner shall be marked with a monument so designated by computed X and Y coordinates which shall appear on the map with a statement identifying this station or monument to an accuracy of 1:15000. When such a monument or station is not available, the tie shall be made to some pertinent and readily recognizable land mark or identifiable point, physical object or structure.
(B) Monuments. Within each block of a subdivision at least two monuments designed and designated as control corners shall be installed. The surveyor shall employ additional monuments, if and when required. All monuments shall be constructed of concrete and shall be at least four inches in diameter or square and not less than three feet in length. Each monument shall have imbedded in its top or attached by a suitable means a metal plate of non-corrosive materials and marked plainly with the point, the surveyor’s registration number, the month and year it was installed and the word “monument” or “control corner”. A monument shall be set at least 30 inches in the ground with at least six inches exposed above the ground unless the requirement is impractical.
(C) Property markers. A steel or wrought iron pipe or the equivalent not less than three-fourths inch in diameter and at least 30 inches in length shall be set at all corners, except those located by monuments. A marker shall also be set at a point of curve, point of intersection, property corner, point of tangency and reference point unless a monument has already been placed at said points. Additional markers shall be placed at other points as required.
(D) Accuracy. Land surveys within the town limits shall be at an accuracy of at least 1:10,000 and beyond the town limits an accuracy of not less than 1:7,500 is required.
