(A) Accuracy. The procedure and practice of all survey work done on any subdivision, in the preparation of a final map, shall conform to the accepted standards of the engineer’s profession. The accuracy of all boundary surveys done in connection with any subdivision shall have a precision of one in 10,000.
(B) Existing centerlines. In the event the City Engineer, the State Highway Engineer or the County Director of Public Works has established the centerline of any street or alley in or adjoining a subdivision. the final map shall show such centerline together with reference to a filed book or map showing such centerline and the monuments which determine its position. If determined by ties, that fact shall be stated upon the final map.
(C) Existing monuments. Each final map shall fully and clearly show and identify such monuments or other evidence determining the boundaries of the subdivision as were found on the ground, together with sufficient corners of adjoining subdivisions, by lot and block number, tract name and place of record, or by section, township and range, or other proper designation as may be necessary to locate precisely the limits of the subdivision and to permit the survey to be retraced.
(D) New monuments.
1. The location and size of all monuments placed in making the survey shall be shown and, if they were reset by ties, that fact shall be shown. All monuments on the exterior boundary of the subdivision, except those within construction zones, shall be placed prior to the approval of the final map. All interior monuments shall be set subsequent to the completion of the subdivision improvements and security shall be presented by the subdivider as provided for in the Subdivision Map Act, Cal. Gov’t Code § 66496.
2. Notice of setting final monuments shall be given and payment to the engineer or surveyor for setting of final monuments shall be made provided by the Subdivision Map Act, Cal. Gov’t Code § 66497.
3. Monuments shall be placed and shall be of the type specified by the city’s improvement standards.
4. The City Engineer may allow the use of offset monuments, properly tied to reference monuments, when necessary due to terrain, waterways or other monuments other than those specified in subsections (D)1. and (D)2. of this section.
(E) Monuments; replacement. Before street improvements are accepted, all existing monuments disturbed by the placement of any improvements shall be reset.
(F) Bench marks. Bench marks shall be set at locations required by the City Engineer. The datum for the area within the city shall be based upon datum established by the United States coast and geodetic survey sea level datum, 1929, as amended.
(G) Standard plaque; numbering and location; information. Identification of monuments and bench marks shall be through the use of a standard plaque. Descriptions of all monuments and bench marks shall be furnished to the City Engineer for inclusion in his or her records.
(H) California coordinate system. All surveys required by this title, or necessary to the subdivision of land, shall conform to the California coordinate system when required by the City Engineer. When required, each final map shall show the California coordinate of every monument, and all California coordinates shall be issued and shown on all traverse closure sheets, and other notes and ties which are required by § 6-7-20 of this chapter.
(I) Mathematical accuracy. The blocks and lots of each final map or approved map or record shall have a mathematical accuracy of closure to one in 10,000.
