A.
Streets. All proposed streets, and those existing streets which may be increased in width, shall be monumented along one side of the right-of-way:
(1)
At points of curvature and-points of tangency.
(2)
For easements to be dedicated to the Township as may be determined by the Township Engineer.
(3)
At such places where topographical or other conditions made it impossible to sight between two otherwise required monuments, intermediate monuments shall be placed.
(4)
At such other place along the line of streets as may be determined by the Township Engineer so that any street may be readily defined for the future.
B.
Lot corners; pins. All lot corners shall be clearly identified by either a monument or an iron pin. Where iron pins are used, they shall be a minimum of one-half-inch diameter solid bar or reinforcing rod, shall be a minimum of 18 inches in length, and shall be driven level with finished grade.
C.
Monuments.
(1)
All monuments shall be placed by a registered professional engineer or surveyor so that the scored point (an indented cross or drill hole of not more than one-fourth-inch diameter in the top of the monument) shall coincide exactly with the point of intersection of the lines being monumented. Monuments placed on street rights-of-way and easements for public, drainage, or utility use shall be concrete or stone, tapered (four-inch square top, five-inch square bottom) and 30 inches in length.
(2)
The tops of monuments shall be set level with the finished grade of the surrounding ground, except:
(a)
Monuments which are placed within the lines of existing or proposed sidewalks shall be located beneath the sidewalks so that their tops will not be affected by lateral movement of the sidewalks.
(b)
Where monuments are located beneath a sidewalk, proper access to them shall be assured.
(c)
In wooded areas, monuments shall protrude six inches above the surface of the ground.
