16.18.140 Preparation of maps - Monuments.
   A.   The final or parcel map shall fully and clearly show what stakes, monuments or other evidence to determine the boundaries of the subdivision were found on the ground, and the adjacent corners of each adjoining subdivision or portion thereof, by lot and block numbers, tract name or number and place of record, by section, township and range, or other proper designation.
   B.   The procedure and practice of all survey work done upon any such subdivision shall conform to the accepted standards of the engineering profession.
   C.   All monuments shall not be less substantial than a three-quarter-inch diameter pipe eighteen inches long or a five-eighth-inch diameter steel reinforcing bar eighteen inches long with a brass tag, aluminum or plastic cap bearing the registration number of the engineer or surveyor who set the monument, and shall be subject to inspection and approval by the City Engineer. "Permanent" monuments shall be set in concrete. Before street improvements are accepted, all monuments disturbed by the improvements shall be reset.
   D.   In making the survey for the subdivision, the engineer or surveyor shall set "permanent" monuments at all angle and curve points on the exterior boundaries of the subdivision, in all street intersections, at all angle points of street lines, and at all curved points, both simple and compound, of street lines. "Permanent" monuments at street intersections and at angle and curved points of street lines shall set on street centerlines, unless otherwise directed by the City Engineer; provided, however, that the "permanent" monuments need not be set at intervals of less than four hundred feet.
   E.   The "permanent" monument shall be set in the ground upright with the metal marker centered in the concrete, by excavating a six-inch minimum diameter hole two feet below the finished grade and pouring the same full of concrete. When streets are required to be paved, the location of such monument and access thereto shall be given by a suitable concrete or cast iron sliding sleeve surmounted by a circular cast iron frame and lid at street surface. In case the monument is not on a street, the metal marker may be set flush with the existing ground surface.
   F.   The engineer and surveyor shall set monuments at all lot corners and at all curve points on lot boundary lines.
   G.   There shall be one or more permanent bench marks for each subdivision, of a type approved by the City engineer and referred to the City datum, set at each street intersection in the curb return or other location approved by the City Engineer. The bench mark shall be a brass disc two inches ± in diameter set in the concrete curb.
