A. 
Each tract map and each parcel map for which a survey is required shall show durable monuments found or set at or near each boundary corner, and at intermediate points (approximately one thousand feet apart) or at such lesser distances as may be made necessary by topography to insure accuracy in the reestablishment of any point or line without unreasonable difficulty. The precise position and character of each such monument shall be shown on the map. Such durable monument shall not be less substantial than an iron pipe of two-inch outside diameter, nor less than two and one-half feet in length, with plug and tack, and set at least two feet into the ground, or of such other character and stability as may be approved by the city engineer. For the purposes of this chapter, a lead and tack set in permanent concrete or masonry shall be considered as a durable monument. The approximate elevation of the top of each such monument with respect to the surface of the ground shall be shown on said map.
B. 
Whenever necessary, in the opinion of the city engineer, centerline monuments shall be set to mark intersections of streets or intersections of streets with the map boundary, or to mark either the beginning and end of curves or the points of intersections of tangents thereof or other intermediate points.
1. 
Each such monument shall not be less durable and substantial than a lead and tack in asphaltic concrete or cement pavements, a two-inch pipe set not less than twelve inches below the surface or at such depth as may be approved by the city engineer, or a spike not less than six inches long in bituminum macadam pavements.
2. 
For each centerline monument set, the engineer or surveyor under whose supervision the survey has been made shall furnish to the city engineer a set of notes clearly showing the ties between the monument, and a sufficient number (normally four) of durable, distinctive reference points or monuments.
3. 
Such reference points or monuments may be leads and tacks in sidewalks, or two-inch by two-inch stakes set back of the curbline and below the surface of the ground, or a substitute thereof which appears not likely to be disturbed.
4. 
Each set of notes submitted shall conform in all respects to the standardized office records of the city engineer. All such notes shall be indexed and filed by the city engineer as a part of the permanent public records of his or her office.
C. 
All monuments found or set as required herein shall be permanently and visibly marked or tagged within the registration or license number of the engineer or surveyor under whose supervision the survey was made.
D. 
All boundary monuments shall be set prior to filing the tract map or parcel map. Interior street centerline monuments may be set subsequent to filing of the tract map or parcel map. The tract map or parcel map shall show which monuments are in place and which are to be set. Prior to certification of the tract map or parcel map by the city engineer, the subdivider shall submit a written agreement in which he or she agrees that monuments deferred will be set within a specified time and that all notes required will be furnished with a specified time.
E. 
All monuments shall be subject to inspection and approval of the city engineer.
(Prior code § 27-57.01)
Interior monuments need not be set at the time the map is recorded, if the engineer or surveyor certifies on the map that the monuments will be set at a specified date and security is given to the legislative body guaranteeing the payment of the cost of setting such monuments.
(Prior code § 27-57.02)
Each tract map and each parcel map for which a survey is required shall show evidence found on the ground of sufficient corners or prior surveys or such other evidence as may be suitable to precisely locate the boundaries of the division or reversion shown on the map. Each stake, monument or other object found shall be fully described and referenced. The method used to establish each point or line shall be clearly shown and explained on the map.
(Prior code § 27-57.05)
