A. An accurate and complete survey of the land to be subdivided shall be made by a registered civil engineer or licensed land surveyor. All monuments, property lines, centerlines of streets, alleys and easements adjoining or within the subdivision shall be tied into the survey. The allowable error of closure on any portion of the final map shall not exceed 1/10,000 for field closures and 1/20,000 for calculated closures.

B. At the time of making the survey for the final map, the engineer or surveyor shall set sufficient durable monuments to conform with the standards described in Cal. Bus. & Prof. Code § 8771 so that another engineer or surveyor may readily retrace the survey. At least one exterior boundary line shall be monumented prior to recording the final map. Other monuments shall be set or bonded for as required by the County Surveyor. (Formerly 23.07.003)
