The final map shall be prepared by a registered civil engineer or licensed land surveyor in a form acceptable to the County Engineer and in conformity with the provisions of the Subdivision Map Act and as follows:
(A) The final map 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. 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 not less than one inch equals 100 feet or as may be necessary 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. When four or more sheets including the certificate sheet are used, a key sheet shall be included. All printing or lettering on the map shall be of one-eighth inch minimum height and of such shape and weight as to be readily legible on prints and other reproductions made from the original drawings.
