* Prior ordinance history: Ord. 543.

Whenever any subdivision of land is plotted or divided into lots by blocks, and whenever any addition to any subdivision is laid out into lots or blocks for the purpose of sale or transfer, the county surveyor, under the direction and with the approval of the board of supervisors, may make an official map of the town or subdivision, giving to each block on the map a number, and to each lot or subdivision in the block a separate number or letter, and giving names to the streets, avenues, lanes, courts, commons or parks, as may be delineated on the official map. (Ord. 278N § 15(part), 2004).

Any surveyor or engineer, licensed in the state of California, under the review of the county surveyor may prepare an official map to be filed for record pursuant to subdivisions (D) and (E) of Section 66499.35 of the California Government Code. The map shall be prepared in accordance with the following map format specifications:
A. It shall be legibly drawn, printed or reproduced by process guaranteeing a permanent record in black on tracing cloth or polyester base film. Certificates, affidavits and acknowledgments may be legibly stamped or printed upon the map with opaque ink. If ink is used on polyester base film, the ink surface shall be coated with a suitable substance to assure permanent legibility.
B. The size of each sheet shall be eighteen by twenty-six inches. A marginal line shall be drawn completely around each sheet leaving an entirely blank margin of one inch. The scale of the map shall be large enough to show all details clearly and enough sheets shall be used to accomplish this end. The particular number of the sheets and the total number of sheets comprising the map shall be stated on each of the sheets, and its relation to each adjoining sheet shall be clearly shown.
C. All survey and mathematical information and data necessary to locate all monuments and to locate and retrace any and all interior and exterior boundary lines appearing there shall be shown, including bearings and distances of straight lines, in radii and arc length or chord bearing and length for all curbs, and any information which may be necessary to determine the location of the centers of curbs and ties to existing monuments used to establish the subdivision boundaries.
D. Each parcel shall be numbered and each block may be numbered or lettered. Each street shall be named or otherwise designated.
E. The exterior boundary of the land included within the subdivision shall be indicated by distinctive symbols and clearly so designated. The map shall show the definite location of the subdivision, and particularly its relation to surrounding surveys.
If the map includes a “designated remainder” parcel, and the gross area of the “designated remainder” parcel or similar parcel is five acres or more, that remainder parcel need not be shown on the map and its location need not be indicated as a matter of survey, but only by deed reference to the existing boundaries of the remainder parcel.
A parcel designated as “not a part” shall be deemed to be a “designated remainder” for purposes of this section.
F. On or after January 1, 1987, no additional requirements shall be included which do not affect record title interests. However, the map shall contain a notation or reference to additional information required under the provisions of Title 17 of this code. (Ord. 278N § 15(part), 2004).

Payment for the services of the county surveyor, and any charges required for processing the official map by the county surveyor, shall be the responsibility of the applicant. (Ord. 278N § 15(part), 2004).

The official map shall include a surveyor certificate stating that the map was prepared pursuant to the provisions of Government Code 66499.52 and shall include an approval certificate of the county surveyor. The certificate shall be signed, and below or immediately adjacent to the signature, shall indicate the license or registration number with expiration date of the registered civil engineer or license land surveyor preparing and approving the official map. (Ord. 278N § 15(part), 2004).

The engineer or surveyor under the direction and with the approval of the board of supervisors may compile the map from maps on file, or may resurvey or renumber the blocks, or renumber or reletter the lots in the blocks, or change the names of the streets. (Ord. 278N § 15(part), 2004).

Each and every map made and adopted pursuant to the provisions of this chapter shall be certified under the hands of a majority of the members and the presiding officer and secretary and official seal of the board of supervisors. The certificate shall set forth in full the resolution adopting the map, with a date of adoption. (Ord. 278N § 15(part), 2004).

The map, so certified, shall be forthwith filed in the office of the county recorder. The recorder shall immediately securely fasten and bind each map so filed in one of a series of firmly bound books to be provided, together with the proper indices thereof and appropriately marked for the reception of the maps provided for in the division of the Government Code governing official maps. (Ord. 278N § 15(part), 2004).

The maps shall become an official map for all purposes when certified, filed and bound, and not before. (Ord. 278N § 15(part), 2004).

Whenever the board of supervisors adopts a map as provided in this chapter as the official map of a subdivision, town or county, it shall be lawful and sufficient to describe the lots or blocks in any deeds, conveyances, contracts, or obligations affecting any of the lots or blocks as designated on the official map, a reference sufficient for the identification of the map being coupled with the description. (Ord. 278N § 15(part), 2004).

All surveys and the field notes thereof made by any engineer or surveyor, under the provisions of this chapter, or in surveying officially any lots or parcels of land in any town or county for the purposes of any map under this chapter, shall be filed in the office of the surveyor or engineer, as the case may be, and shall become a part of the public records of the county. (Ord. 278N § 15(part), 2004).
