§ 9204.32. Monuments. — Carson Zoning Code

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 (1,000) feet apart, or at such lesser distances as may be made necessary by topography to ensure 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 be not less substantial than an iron pipe of a two (2) inch outside diameter, not less than two and one-half (2-1/2) feet in length, with plug and tack, and set at least two (2) 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.

Each such monument shall be not less durable and substantial than a lead and tack in asphaltic concrete or cement pavements; a two (2) inch iron pipe set not less than twelve (12) inches below the surface, or at such depth as may be approved by the City Engineer; or a spike not less than six (6) inches long in bituminous macadam pavements.

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 (4)) of durable, distinctive reference points or monuments.

Such reference points or monuments may be leads and tacks in sidewalks, or two (2) inch by two (2) inch stakes setback of the curbline and below the surface of the ground, or a substitute therefor which appears to be not likely to be disturbed.

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 office.

c. All monuments found or set as required herein shall be permanently and visibly marked or tagged with the registration or license number of the engineer or surveyor under whose supervision the survey was made.
d. At least one (1) exterior boundary line of the land being subdivided shall be monumented prior to the filing of the final tract map or final parcel map. Interior street centerline monuments and the remainder of the boundary monuments may be set subsequent to filing the final tract map or final 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 agrees that monuments deferred will be set within a specified time and that the notes required in CMC § 9204.32(b) will be furnished within a specified time.
e. All monuments shall be subject to inspection and approval of the City Engineer.
