Health & Saf. Code, § 8550

Every cemetery authority, from time to time as its property may be required for interment purposes, shall:

(a) In case of land, survey and subdivide it into sections, blocks, plots, avenues, walks or other subdivisions; make a good and substantial map or plat showing the sections, plots, avenues, walks or other subdivisions, with descriptive names or numbers.

(b) In case of a mausoleum, or crematory and columbarium it shall make a good and substantial map or plat on which shall be delineated the sections, halls, rooms, corridors, elevations, and other divisions, with descriptive names or numbers.

(c) The maps or plats shall be clearly and legibly drawn, printed, or reproduced by a process guaranteeing a permanent record in black on tracing cloth or polyester base film. If ink is used on a polyester base film, the ink surface shall be coated with a suitable substance to insure permanent legibility. The size of each sheet shall be 18 by 26 inches or as otherwise prescribed by the county recorder or local agency. A marginal line shall be drawn completely around each sheet, leaving an entire 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 relationship to each adjoining sheet shall be clearly shown.

(d) Upon modification of an existing section after January 1, 1990, or development of a new section after January 1, 1990, the cemetery authority shall amend and file with the county recorder or local agency the maps or plats as described in subdivisions (a), (b), and (c). Within 12 months of the initial sale, the cemetery authority shall file with the county recorder or local agency the map or plat. For purposes of this subdivision, “section” means a burial space, mausoleum, or columbarium.
