17.11.120 Survey data and information to be shown on final map or parcel map.
17.11.010 Survey procedure and practice.
The procedure and practice of all survey work done on any subdivision, whether for preparation of a final map or parcel map, shall conform to the standard practices and principles of land surveying, the Land Surveyor’s Act of the State of California, and the provisions of this chapter. [Ord. 09-026.]
17.11.020 Traverse.
The traverse of the exterior boundaries of the tract computed from field measurements of the ground must close within a limit of error of one (1) foot to twenty thousand (20,000) feet of perimeter before balancing survey. [Ord. 09-026.]
17.11.030 Survey data.
The engineer or surveyor making the survey shall show references, ties, locations, elevations and other necessary data relating to monuments set in accordance with the requirements of this title.
If exterior boundary monuments are to be set after recordation of the final map or parcel map, as provided by DMC 17.11.060, Boundary monuments, the City Engineer shall require, prior to accepting such map for filing, the reference of said monuments to a sufficient number of adjacent reference points to accurately set each boundary monument after recordation of said map, the setting of only a portion of the boundary monuments, or the submission of complete field notes as evidence of a thorough survey. [Ord. 09-026.]
17.11.040 Grid monuments.
Wherever the City Engineer has established a system of coordinates which is within a reasonable distance of the subdivision boundary, as determined by the City Engineer, the field survey shall be tied into such system. [Ord. 09-026.]
17.11.050 Monuments.
In making the survey of the subdivision, the engineer or surveyor shall set sufficient permanent monuments so that the survey, or any part thereof, may be readily retraced.
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 (1) exterior boundary line shall be monumented prior to recording the final map. Other monuments shall be set as required by the City Engineer. [Ord. 09-026.]
17.11.060 Boundary monuments.
Monuments shall be set on the exterior boundary of the subdivision at all corners, angle points, beginnings and ends of curves and at intermediate points approximately one thousand (1,000) feet apart. The locations of inaccessible points may be established by ties and shall be so noted on the final map or parcel map.
All exterior boundary monuments shall be set prior to recordation of the final map or parcel map unless extensive grading operations or improvement work makes it impractical to set such monuments. In the event any or all of the boundary monuments are to be set after recordation of the final map or parcel map, prior to the submission of such map to the City Engineer for filing, the engineer or surveyor making the survey shall, in addition to furnishing field notes showing the boundary survey as required by DMC 17.11.030, Survey data, furnish evidence acceptable to the City Engineer to substantiate his or her reasons for deferring the setting of such monuments until after recordation of such map. [Ord. 09-026.]
17.11.070 Interior monuments.
Interior monuments shall be set along streets as provided in City Standard Specifications. Interior monuments may be set after the final map or parcel map is recorded. [Ord. 09-026.]
17.11.080 Deferred monuments.
In the event any or all of the required monuments are to be set after recordation of the final map or parcel map, the engineer or surveyor shall follow procedures per Sections 66496 and 66497 of the Subdivision Map Act. [Ord. 09-026.]
17.11.090 Monument type and positioning.
Boundary monuments shall consist of one (1) inch diameter iron pipes, eighteen (18) inches long or as approved by the City Engineer. Temporary interior monuments for construction purposes shall consist of two (2) inch by two (2) inch by eight (8) inch long wood hubs with cup tacks. Permanent interior monuments shall be in accordance with City Standard Specifications. [Ord. 09-026.]
17.11.100 Monument identification marks.
All boundary monuments shall be permanently and visibly marked or tagged with the registration or license number of the engineer or surveyor who signs the engineer’s or surveyor’s certificate and under whose supervision the survey was made. [Ord. 09-026.]
17.11.110 Replacement of destroyed monuments.
Any boundary monument set as required herein which is disturbed or destroyed before acceptance of all improvements by the City shall be replaced by the subdivider’s engineer or surveyor. [Ord. 09-026.]
17.11.120 Survey data and information to be shown on final map or parcel map.
The following survey data and information shall be shown on each final map or parcel map for which a field survey was made pursuant to the provisions of this title:
A. The basis of bearing used in the field survey, making reference to a recorded subdivision map or other record acceptable to the City Engineer.
B. Stakes, monuments (together with their precise position) or other evidence found on the ground to determine the boundaries of the subdivision.
C. Corners of all adjoining properties identified by lot and block numbers, subdivision names, numbers and page of record or by section, township and range or other proper designation.
D. All information and data necessary to locate and retrace any point or line without unreasonable difficulty.
E. The location and description of any required monuments to be set after recordation of the final map, and the statement that they are “to be set.”
F. Bearing and length of each lot line, block line and boundary line and each required bearing and distance.
G. Length, radius and bearings of terminal radii of each curve and the bearing of each radial line to each lot corner on each curve.
H. The center line of any street or alley in or adjoining the subdivisions, profiles, estimated costs and specifications.
The form, layout, scale and other particulars of the plans, and number of copies to be provided, shall be in accordance with the requirements of City Standard Specifications. [Ord. 09-026.]
