Chapter 17.848 — SURVEYS AND MONUMENTS

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. 2017-0009 § 28)

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 foot to 20,000 feet of perimeter before balancing survey. (Ord. 2017-0009 § 28)

When required by the director of public works, 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 these regulations. (Ord. 2017-0009 § 28)

Wherever the director of public works has established a system of coordinates that is within a reasonable distance of the subdivision boundary, as determined by the director of public works, the field survey shall be tied into such system. (Ord. 2017-0009 § 28)

A. 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.

B. At the time of making the survey for the final map or parcel map, the engineer or surveyor shall set sufficient durable monuments to conform with the standards described in section 8771 of the California Business and Professions Code so that another engineer or surveyor may readily retrace the survey. The exterior subdivision boundary shall be sufficiently established from record monuments prior to recording the final map or parcel map. Other monuments necessary for the establishment of the subdivision may be required by the director of public works. (Ord. 2017-0009 § 28)

A. 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 as determined by the director of public works. The locations of inaccessible points may be established by ties or witness monuments and shall be so noted on the final map or parcel map. B. 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 director of public works for filing, the engineer or surveyor making the survey shall, in addition to

furnishing field notes showing the boundary survey as required by section 17.848.030, furnish evidence acceptable to the director of public works to substantiate his or her reasons for deferring the setting of such monuments until after recordation of such map. (Ord. 2017-0009 § 28)

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's or surveyor's certificate shall specify the date, established by the director of public works, by which the monuments will be set, and the field notes thereon furnished. The subdivider shall, prior to the submission of such map to the director of public works for filing, furnish performance security in a form approved by the director of public works, and in an amount established by resolution of the city council for each boundary and interior monument to be deferred. After deferred monuments have been set, written notice shall be given to the director of public works pursuant to California Government Code section 66497, and performance security shall be returned to the subdivider. In the event the deferred monuments are not set within the period of time specified on the engineer's or surveyor's certificate, or within any approved extended period of time, and provided that all improvement work has been completed, the director of public works shall, by written notice, forthwith direct the engineer or surveyor of record to, within 60 days of the date of such directive, set such monuments and furnish such field notes as were agreed to be set and furnished on said certificate. If the engineer or surveyor fails to comply with said directive within the specified time, and if no request for an extension of time has been submitted in writing and granted within such time, the director of public works shall, without further notice, submit a written complaint and request for disciplinary action against said engineer or surveyor to the State Board of Registration for Civil and Professional Engineers. (Ord. 20170009 § 28)

A. Unless otherwise approved by the director of public works, boundary monuments shall consist of one inch diameter iron pipes, eighteen inches long.

B. Interior monuments shall be set along street and alley center lines at the beginnings and ends of curves, at points of intersection with lines of other existing and proposed streets and alleys, and at the points of intersection with the exterior boundary lines. Interior monuments may be set after the final map or parcel map is recorded. Interior monuments shall be 2 ½" by ¼ " mag nails, except where concrete survey monuments are required by the director of public works.

C. Concrete survey monuments shall be in accordance with the most recent City of Sacramento Standard Specifications for Public Construction, and the number and location shall be determined by the director of public works. (Ord. 2017-0009 § 28)

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. 2017-0009 § 28)

Any boundary monument set as required herein which is disturbed or destroyed before acceptance of all improvements by the city, and any interior monument which is disturbed or destroyed before being located and referenced by the city at the time of construction, shall be replaced by the subdivider's engineer or surveyor. (Ord. 2017-0009 § 28)

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 these regulations:

• A. The basis of bearing used in the field survey, making reference to a recorded final map, parcel map or other record acceptable to the director of public works;

• 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. Chord length, chord bearing, and radius of each curve or as required by the director of public works; and

• H. The center line and width of any street or alley in or adjoining the subdivisions.

The form, layout, scale and other particulars of the map shall be consistent with any required improvement plans, and shall be in accordance with the requirements of the director of public works. (Ord. 2017-0009 § 28)
