Generally, all work shall conform to standards set forth by the American Congress of Surveying and Mapping and the following minimum standards:
(a) Monuments. Monuments shall be a minimum size of four (4) inches square and thirty-six (36) inches long, and made of concrete; or by setting a four (4) inch diameter cast iron, steel or plastic pipe filled with concrete using an iron rod in the center or a brass or copper plate on the top for marking the exact point. Concrete monuments shall be set at the following locations:
(1) Intersections of all lines forming angles in the boundary lines of the subdivision tract;
(2) At such intermediate points on line as may be required by the City Engineer; and
(3) At such points along street or road right-of-way lines as may be required by the City Engineer so as to provide future points of reference.
(b) Markers. Markers shall be solid metal at least thirty (30) inches long and five-eighths (5/8) of an inch in diameter. Markers shall be set at the following locations:
(1) At all lot corners except those monumented;
(2) At all points of tangent or points of curvature along interior street rights-of-way;
(3) At points of change in direction along lot lines; and
(4) At all points where lot lines intersect street curves.
(c) Placement of Monuments and Markers. Monuments and markers shall be set in exact position by a Professional Surveyor in accordance with the bearings and distances shown on the Plat of Record. Monuments shall be set flush with the finished ground level. Markers shall be driven into the ground to within one-half (1/2) inch of finished ground level. Guard stakes or pins shall be set adjacent to monuments and markers to provide for protection against disturbance and to aid in future location. Any monuments or markers that are moved or removed shall be replaced by a Professional Surveyor at the Subdivider's expense until such time as the Subdivider's involvement in the plat ceases, after which the landowner shall bear the expense for resetting by the Surveyor.
