The following provisions shall apply to monuments and markers placed in subdivisions regulated by this chapter:
A. The developer of any subdivision shall install within that subdivision, permanent reference monuments and markers, placed flush with the ground, in accordance with the provisions of this section.
B. All monuments and markers shall be properly set in the ground and approved by a registered land surveyor prior to the time the Planning Commission recommends approval of the final plat.
C. Existing monuments or markers shall not be disturbed, unless absolutely necessary, in which case the monuments or markers shall be replaced at the exact spot from which they were removed.
D. The location of all monuments and markers shall be included on the final plat.
E. Three (3) types of monuments and markers shall be used for different situations. The following specifications shall be applicable to each type of situation:
1. Type A. Permanent reference monuments shall be placed at the intersection of the centerlines of rights-of-way, regardless of whether the paving of the street is centered in the right-of-way. There shall be a minimum of two (2) such monuments in each subdivision. If no two (2) of the intersection monuments are within line-of-sight of each other, an additional marker shall be placed on the right-of-way centerline, so as to establish a straight line which can be seen (line-of-sight) from one (1) end to the other. An additional such marker shall be placed at the center-point of the turnaround in each cul-de-sac. These monuments shall be of non-corrosive metal plate, set in accordance with the following diagram, and each shall be stamped with a cross at the point of the intersection and the elevation to the nearest tenth (0.10) of a foot.
F. Type B. Permanent reference markers shall be placed at each turning point in the external boundary of the subdivision to be set in concrete in accordance with the following diagram:
G. Type C. Permanent reference markers shall be placed at:
1. Each corner of each block;
2. Each corner of each lot;
3. The points of curvature and points of tangency of all inside and outside rights-of-way lines;
4. The point of intersection of the outside line of a curve in a street right-of- way; and
5. On all quarter (1/4) section points within the subdivision or on its perimeter to be set in unexcavated earth.
