A. Minimum Requirements. Monuments shall consist of a brass cap two and one-half inches in diameter riveted to a three-fourths-inch galvanized iron pipe 30 inches or more long. The lower three inches of the pipe should be split and, after beating, spread out at right angles to the pipe. The pipe shall be thoroughly tamped when set. Where monuments are set in untravelled areas, the brass cap should be from two to six inches above the ground. Markers consisting of a one-half-inch rod driven well below the surface may be placed in roadways or travelled ways. Where markers are placed in roadways or travelled ways, there should be at least two reference monuments set 90 degrees apart and equidistant from the marker. Reference monuments should be placed on property lines and outside of graded areas. If the grading is liable to extend to or beyond the property line, then the reference monument shall be placed behind or beyond the property line.

B. Every subdivision shall have at least two adjacent monuments set in concrete, not less than 10 inches in diameter and 36 inches deep, located preferably at exterior angles farthest from existing city or government monuments. Monuments shall be set at all exterior angle points in a subdivision, a three-fourths-inch by 30-inch galvanized iron pipe shall be set in a manner similar to that described in subsection (A) of this section at all block corners which are not monumented. The line of sight between adjacent monuments shall be unobstructed. The distance and bearings between monuments shall be shown. The distance between adjacent monuments shall not exceed 400 feet. No part of any subdivision shall be further than 400 feet from a monument. All monuments shall be tied to the subdivision lines and identified on the plat. All lot corners shall be marked in a professional manner.

C. Brass caps used as monuments shall be purchased at cost from the city clerk. The brass caps will bear the following wording: “Official Survey Monuments – Penalty for Disturbing.” Brass caps for reference markers shall bear the following wording: “Official Survey Reference Monument – Penalty for Disturbing.” Reference monuments shall not be buried but shall be set flush with the ground. Monuments of particular importance should be set in concrete. The exact transit point should be shown on the monument by a punch mark. Reference monuments should be similarly marked. Each monument shall be clearly lettered or numbered by stamping with steel so that it may be easily identified in the field. The letters or numbers shown on the monument shall also be delineated on the plat. Where monuments or reference monuments are located on the exterior lines of a subdivision, the name or initials of the subdivision shall be shown. The year that the monument or reference monument is set shall be shown. The surveyor may, if he desires, add other pertinent information such as his initials or registration number.
