This section is included in your selections.

A. At the time of making the survey for the final tract or parcel map, the engineer or surveyor shall set sufficient durable monuments to conform with the standards described in Section 8771 of the Business and Professions Code so that another engineer or surveyor may readily retrace the survey.

B. Such engineer or surveyor shall set monuments as follows:

1. Set city standard monuments and encasements at all intersections of street centerlines, except as noted in subsection (B)(1.1) of this section, beginning and ending of all curves on streets within the subdivision and at the intersection of the centerline of the streets and the subdivision boundary, except that city standard monuments and encasements need not be set at the intersection of the centerline of the streets and phase boundaries, unless that phase boundary monument is required to comply with other provisions of this chapter. On all curved streets, a sufficient number of monuments shall be set so that connecting chords shall be wholly within the street roadway between curbing. The engineer or surveyor shall measure the vertical elevation based upon data approved by the city engineer, data for each city standard monument set and shall provide a record of this data to the city engineer.

1.1. At the intersection of streets which form a knuckle, street centerline monuments shall be set at the beginning and ending of the centerline curve connecting the two streets.

2. Set two-inch iron pipe twenty-four inches long, filled with concrete and properly tagged, or with a two-inch by two-inch by twelve-inch redwood stake driven into the center and properly tagged or equal as approved by the city engineer, at all angle points and beginning and ending of all curves on the exterior boundary of the subdivision. All boundary monuments shall be in place prior to recordation of the map. The city engineer may, by a field survey, satisfy him or herself that all monuments actually exist and that their positions are correctly shown. Depth of boundary monuments shall be not less than six inches or more than thirty inches.

3. Set two-inch by two-inch by twelve-inch redwood stakes with tag, iron rod with cap or iron pipe with cap and properly tagged at all angle points and beginning and ending of all curves on the boundary of each lot or parcel, which angle point is not covered in subsection (B)(1) or (2) of this section. For front lot or parcel corners, reference points, consisting of “penny” tags epoxied in place together with chisel marks on the top of curbs, may be substituted for the required redwood stake, iron rod or iron pipe. For rear lot corners of double-frontage lots, reference points, consisting of concrete nails and tags mounted on the rear masonry wall, on the lot side, at a visible elevation, may be substituted for the required redwood stake, iron rod or iron pipe.

4. When any of the above-described boundary points fall in a concrete sidewalk, curb, wall, coping, etc., such points shall be marked with a concrete nail and tag.

5. All monuments in subsections (B)(1) and (2) of this section shall be so set as to insure an unobstructed sight between adjacent monuments, whenever feasible, and in no case shall the distance between monuments exceed two thousand seven hundred feet, unless prior approval is obtained from the city engineer.

6. All monuments shall be permanently marked with the certificate number of the engineer or surveyor setting it, preceded by the letters R.C.E. or L.S. respectively, as the case may be.

7. The character, type and position of all monuments and encasements shall be noted on the final map. If a monument is replaced, indicate type and condition of monument found and the date of replacement.

8. A traverse of the boundaries of the map and of all the lots, or parcels, and blocks must close within a limit of error not in excess of one foot in twenty thousand feet.

9. All distances must be expressed on the map to the nearest one one-hundredth of one foot.

10. Any monuments or stakes disturbed by the improvements shall be reset. Where no streets are to be improved, the subdivider shall post a faithful performance bond to guarantee the setting of all the above stakes and monuments.
