1. Monuments Shown on Final Plan. The location of all existing and proposed monuments, lot line markers, property corners, and drill holes shall be shown on the final plan. Those that are proposed shall be labeled as such. Drilled holes in curbing shall be referenced mathematically to a point on the right-of-way line.
2. New Monuments. Three monuments shall be spaced around the proposed project with precise bearings and distances labeled which reference those monuments to known property corners.
A. Two such monuments shall be consecutive corners along street rights-of-way and the third may be placed either on the boundary or internal to the site.
B. Longitude and latitude coordinates of the monuments shall be shown on the recorded plan.
C. If GPS technology is used, it shall be rectified and calibrated to the State Plane Coordinate System, North American Datum (NAD 83/92). Monuments must be readily accessible and clear of overhead obstructions.
D. A computer readable point file including property lines, corners, rights-of-way, and easements for the site shall be submitted to the Borough prior to plan recordation.
3. Monument Materials. Monuments shall be of concrete or stone, with a flat top having a minimum width or diameter of 4 inches and a minimum length of 30 inches. Concrete monuments shall be marked with a 3/4-inch copper, brass dowel, or drill hole; stone or precast monuments shall be marked on the top with a drill hole.
4. Existing and Proposed Property Line and Right-of-Way Markers. Markers shall be set at all points where lot lines intersect curves, at all angles in property lines, at the intersection of all other property lines, and at the street right-of-way.
5. Marker (Pin) Materials.
A. Markers shall consist of iron pipes or steel bars at least 30 inches long and not less than 5/8 of an inch in diameter.
B. Drill holes shall be drilled in concrete curbs (with or without PK nails or discs) having a minimum diameter of 1/4 inch. The depth of the holes shall be such that a PK nail or disc, if used, can be set in as close to the surface of the curb as possible. Minimum depth without the use of PK nail or disc shall be ½ inch. In the absence of PK nails or discs, chisel or saw marks shall be used to facilitate and identify the drill hole locations.
6. Certification of Monuments and Markers.
A. All monuments, markers, and drilled holes shall be placed by a registered professional land surveyor so that the scored marked point, or center of the drilled hole shall coincide with the point of intersection of the lines being monumented or marked.
B. The plan shall provide a note indicating when the monuments and markers are to be set.
C. All monuments and markers shall be inspected and certified by the Borough Engineer as an improvement.
