Fresno County Municipal Code Ch. 17.44 Surveys

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 engineering profession. The accuracy of all boundary surveys done in connection with any subdivision shall have a precision of one in ten thousand.

(Prior code, § 700.700A)

In the event the director of public works, the State Highway Engineer, or any city engineer 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 field 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.

(Prior code, § 700.700B)

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.

(Prior code, § 700.701A)

A. The location, size and depth of all monuments placed in making the survey shall be shown and if any 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 a bond shall be presented by the subdivider as provided for in Section 66496 of the Subdivision Map Act.

B. Monuments shall be placed and shall be of the type specified below:

1. All lot corners and changes of direction on all interior and exterior boundaries shall be monumented by three-quarter inch by twenty-eight inch pipe, permanently and visibly marked or tagged with the certificate number of the surveyor or civil engineer setting it, each number preceded by the letters "L.S." or "R.C.E.," respectively as the case may be.

2. The centerline of every street in the subdivision, including border streets, shall have monuments in accordance with the improvement standards, intervisible, and not more than four hundred feet apart.

C. The director public works may allow the use of off-set monuments, monuments, properly tied to reference monuments, when necessary due to terrain, waterways or other unusual circumstances. The director of public works may also allow the use of durable monuments other than those specified in 1 an 2 above.

(Ord. 520-A-14, § 30, 1975; prior code, § 700.701B)

Before street improvements are accepted, all existing monuments disturbed by the placement of any improvements shall be reset.

(Prior code, § 700.701C)

Bench marks shall be set at locations required by the director of public works. The datum for the area bounded by Chestnut, Marks, Shaw and Church Avenues shall be based on city of Fresno datum. The area outside the above-named area including the boundary streets shall be based on the datum established by the United States Coast and Geodetic Survey Sea Level Datum 1929, as amended.

(Prior code, § 700.701D)

Identification of monuments and bench marks shall be through the use of Fresno County standard plaque.

Descriptions of all monuments and bench marks shall be furnished to the department of public works for inclusion in their records.

(Prior code, § 700.701E)

All surveys required by Chapters 17.04 through 17.60, or necessary to the subdivision of land, shall conform to the California coordinate system when required by the director of public works. When required, each final map shall show the California coordinate of every monument and all California coordinates shall be used and shown on all traverse closure sheets, and other notes and ties which are required by Sections 17.32.010—17.32.030.

(Prior code, § 700.702)
