Current through Register Vol. 56, No. 6, March 18, 2024

(a) Geodetic control reference marks are traverse stations and benchmarks established or used by the New Jersey Geodetic Control Survey pursuant to P.L. 1934, c.116. They include the following types:

1. Monument-(Mon), Disk-(DK): A standard United States Coast and Geodetic Survey or New Jersey Geodetic Control Survey disk set in a concrete post, pavement, curb, ledge rock, etc., stamped with a reference number, and used for both horizontal and vertical control.

2. Point (Pt.): A State highway, tidelands (riparian), city, etc. survey marker represented by a chiseled cross, punch hole, brass plug, etc. used for horizontal and vertical control. These stations are not marked, but if there should be an enclosing box, the rim is stamped with a number.

3. Rivet-(Rv.): A standard metal rivet set by the New Jersey Geodetic Control Survey, used for vertical control.

4. Mark-(Mk.): Same as point, but used only for vertical control. In the description of such marks there should appear a mark number followed by an equality sign and then the original name or elevation of the bench mark, and in parentheses the name of the organization which established the mark.

(b) The disturbance of a geodetic control reference mark is discouraged. When a geodetic control reference mark must be moved, raised or lowered to accommodate construction, the New Jersey Geodetic Control Survey shall be contacted at least 60 days prior to disturbance, and arrangements shall be made to protect the position. If the position can not be protected, it may be altered in position after approval by the New Jersey Geodetic Control Survey and under the supervision of a licensed professional engineer or land surveyor using standard methods. Copies of field notes and instruments, tape, and rod specifications including calibration data, shall be submitted to the New Jersey Geodetic Control Survey.

(c) Rationale: Geodetic control reference marks provide the horizontal and vertical references used by land surveyors and engineers to determine most accurately location and elevations on the earth's surface. The rapid disappearance of survey marks and monuments necessitates the implementation of notification procedures prior to the removal, alteration, or destruction of such marks or monuments. This policy was instituted because of the monuments' relative geographic scarcity, their importance to the surveying and engineering community, and the high cost of relocation or referencing a removed, altered, or destroyed mark or monument.
