Prior to the approval of the final plat the following survey reference makers shall be installed.
(A) Permanent concrete monuments four inches in diameter or four inches by four inches square, and not less than three feet long, shall be placed at not less than two corners of the subdivision and at all corners of all intersections, provided that additional monuments shall be placed where necessary so that no point within the subdivision lies more than 500 feet from a monument. Two or more of the required monuments shall be designated as control corners. The top of each monument shall have an indented cross, metal pin, or metal plate to identify properly the location of the point. All monuments shall be shown on the final plat. A monument shall be at least 30 inches in the ground with at least six inches exposed above the ground unless this requirement is impractical.
(B) All lot corners, all points where the street lines intersect the exterior boundaries of the subdivision, and all angle points of curve in each street shall be marked with iron pipe or iron stakes at least one-half inch in diameter and 24 inches long, driven so as to be within one inch of finished grade.
(C) At least one corner of the property surveyed 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 or N.C. Grid System coordinated monument, then this corner shall be marked with a monument so designated and shall be accurately tied to the station or monument by computed X and Y coordinates which shall appear on the map with a statement identifying the station or monument and to an accuracy of at least 1:5,000. When such a monument or station is not available, the tie shall be made to some pertinent and readily recognizable landmark or identifiable point, physical object or structure.
