Alameda County Municipal Code Ch. 16.24 Surveys and Monuments

A final map or a parcel map based upon a field survey shall be made in conformity with the Land Surveyor's Act.

(Prior gen. code § 8-5.0)

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 titles, the subdivider shall take appropriate action to clear said title prior to the filing of the map.

(Prior gen. code § 8-5.1)

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 county surveyor.

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 of these boundary lines can be established from an existing monumented line which is shown on said map.

(Prior gen. code § 8-5.2)

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 (100) feet and angle measurement to twenty (20) inches of angle and not to exceed 0.05 of a foot point position.

(Prior gen. code § 8-5.3)

If the remainder of the original parcel shown on the parcel map has a gross area of five acres or more, said remainder say 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."

(Prior gen. code § 8-5.4)

Whenever the county surveyor or a city engineer has established the center line of a street or alley, ties shall be made to that center line and any monument or reference point thereon.

(Prior gen. code § 8-5.5)

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 or facile reestablishment of any point or line of the exterior boundary.

(Prior gen. code § 8-5.6)

When the exterior boundary of a parcel map is compiled from a filed map, the point of intersection of a new division line with the exterior boundary line shall be monumented or witness thereto.

(Prior gen. code § 8-5.7)

Monuments set shall be durable in nature, such as an iron pipe, and efficiently placed so as not to be readily disturbed.

(Prior gen. code § 8-5.8)

(Prior gen. code § 8-5.11)

All monuments shall be subject to inspection and approval by the county surveyor.

(Prior gen. code § 8-5.12)
