A final map or a parcel map based upon a field survey shall be made in conformity with the Land Surveyor’s Act.
Whenever the field survey indicates a discrepancy from previously recorded data, the record dimensions shall be shown in parentheses and in the same basis of bearings along with the field dimension. When the discrepancy is major and causes a conflict to title, the subdivider shall take appropriate action to clear said title prior to the filing of the map.
A parcel map may be compiled from a recorded or filed map if all of the following conditions are existing:
(A) 
The compiled map is based on a final map or parcel map filed in the office of the County Recorder after January 1, 1964, or on a record of survey filed in the office of the County Recorder after January 1, 1964, and prior to January 1, 1982, or on another final map, parcel map, or record of survey subject to prior approval of the City Engineer.
(B) 
All of the exterior boundary lines are indicated by field bearings and distance on said map.
(C) 
Sufficient survey information exists on said map to locate and retrace the exterior boundary lines.
(D) 
At least one (1) of these boundary lines can be established from an existing monumented line which is shown on said map.
An accurate and complete boundary closure shall be made of the land to be divided. A traverse of the exterior boundaries of the tract or parcel and of each block and lot or parcel when computed, must close within a limit of error of 0.015 of a foot in latitude and/or departure. Street monumentation will be field checked to an accuracy of 0.01 of a foot per one hundred feet (100′) and angle measurement to twenty (20) seconds of angle and not to exceed 0.05 of a foot point position.
If the remainder of the original parcel shown on the parcel map has a gross area of five (5) acres or more, said remainder may be a field survey or may be indicated by deed bearings and distance shown in brackets; the bearings shall be on the same basis of bearings as the survey and the distances shall be in feet and designated as being a “nonsurveyed remainder.”
Whenever the City Engineer has established the centerline of a street or alley, ties shall be made to that centerline and any monument or reference point thereon.
Monuments shall be set, or witness thereto, at all major angle points, and shall be sufficient in number together with existing monuments of record for the perpetuation of facile re-establishment of any point or line of the exterior boundary.
When the exterior boundary of a parcel map is compiled from a file map, the point of intersection of a new division line with the exterior boundary line shall be monumented or witness thereto.
The engineer or surveyor shall set permanent interior monuments in the street areas, located so as to define the street lines bounding each block. Monuments shall be set at all ECs, BCs, and intersections. Due consideration shall be given to visibility of monuments, one from another, for the purposes intended.
(A) 
Exterior boundary monuments shall be set before approval of the final map or parcel map.
(B) 
Interior monuments may be set after approval of the final map or parcel map provided that they be set not later than the time of completion of improvements and adequate improvement security is filed with the City prior to City Engineer approval and certification of the map.
