CA Gov't Code Section 66434

The final map shall be prepared by or under the direction of a registered civil engineer or licensed land surveyor, shall be based upon a survey, and shall conform to all of the following provisions:

(a)

It shall be legibly drawn, printed, or reproduced by a 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 18 by 26 inches or 460 by 660 millimeters. A marginal line shall be drawn completely around each sheet, leaving an entirely blank margin of one inch or 025 millimeters. 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 sheet 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 on the map shall be shown, including bearings and distances of straight lines, and radii and arc length or chord bearings and length for all curves, and any information that may be necessary to determine the location of the centers of curves and ties to existing monuments used to establish the subdivision boundaries.

(d)

Each parcel shall be numbered or lettered and each block may be numbered or lettered. Each street shall be named or otherwise designated. The subdivision number shall be shown together with the description of the real property being subdivided.

(e)

(1)The exterior boundary of the land included within the subdivision shall be indicated by distinctive symbols and clearly so designated. The exterior boundary of the land included within the subdivision shall not include a designated remainder or omitted parcel that is designated or omitted under Section 66424.6. The designated remainder or omitted parcel shall be labeled as a designated remainder parcel or omitted parcel. The map shall show the definite location of the subdivision, and particularly its relation to surrounding surveys.

(2)

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.

(3)

A parcel designated as “not a part” shall be deemed to be a “designated remainder” for purposes of this section.

(f)

On and after January 1, 1987, no additional requirements shall be included that do not affect record title interests. However, the map shall contain a notation or reference to additional information required by a local ordinance adopted pursuant to Section 66434.2.

(g)

Any public streets or public easements to be left in effect after the subdivision shall be adequately delineated on the map. The filing of the final map shall constitute abandonment of all public streets and public easements not shown on the map, provided that a written notation of each abandonment is listed by reference to the recording data or other official record creating these public streets or public easements and certified to on the map by the clerk of the legislative body or the designee of the legislative body approving the map. Before a public easement vested in another public entity may be abandoned pursuant to this section, that public entity shall receive notice of the proposed abandonment. No public easement vested in another public entity shall be abandoned pursuant to this section if that public entity objects to the proposed abandonment.
