(A) After approval of the preliminary plan, survey monuments and markers shall be laid out and set according to the following.
(1) Permanent monuments shall be placed at all corners and at points tangent to curve lines along the boundary of the subdivision. Permanent monuments shall be constructed of concrete, the minimum dimensions of which shall be a minimum of four inches square or four inches in diameter at the top of the monument. The monument shall be a minimum of 36 inches long, with an iron dowel at least three-eighths inches in diameter and two and one-half inches in length embedded in the top of the monument so that the dowel shall be flush with the surface of the monument and placed in the center of the monument marking the corner.
(2) Where concrete monuments are not required to be placed, all lot corners, the ends of all curves, all angle points in any line and all angle points along a meander line shall be marked by galvanized iron pipe not less than three-fourths inch in diameter or solid iron reinforcement bars not less than one-half inch diameter at least 24 inches long. The top of the pipe or bar shall be set level with the established grade of the lot.
(3) For each 20 acres or fraction thereof in the subdivision, one permanent bench mark shall be established at a location approved by the Village Engineer. This bench mark shall be constructed of concrete, four inches by four inches at the top, six inches by six inches at the bottom and 48 inches in length with a brass plate securely fastened to the surface. The brass plate shall be exposed about one inch above final grade and shall be inscribed with the number and elevation of the benchmark. Elevations shall be referred to and certified as U.S.G.S. datum.
(B) All country, state, county or other official benchmarks, monuments or triangulation stations in or adjacent to the property shall be preserved in precise position.
