A. The final parcel map shall be prepared by or under the direction of a registered civil engineer authorized to do land surveying or a licensed land surveyor.

B. Such map may be based either upon a field made in conformity with the Land Surveyor’s Act except that parcel maps in which all parcels exceed twenty acres may be compiled from recorded or filed data when sufficient survey information exists on filed maps to locate and retrace the exterior boundary lines of the parcel map if the location of at least one of these boundary lines can be established from an existing monumented line. (Ord. 4004 § 9, 2001; Ord. 3515 § 1, 1993)
