An accurate and complete survey shall be made of the land to be subdivided.
(Ord. 430 § 5(a), 1950)
A traverse sheet in a form approved by the City Engineer, giving latitudes, departures and coordinates, and showing the mathematical closure, together with complete sets of blue line or black and white check prints of the final map, shall be submitted to the City Engineer for checking and approval. The traverse of the exterior boundaries of the tract and of each block, when computed from field measurements of the ground, must close within a limit of error of one foot to 10,000 feet of perimeter before balancing survey.
(Ord. 430 § 5(b), 1950)
Wherever the County Surveyor or a City Engineer has established a system of coordinates, then the survey shall be tied into such a system.
(Ord. 430 § 5(c), 1950)
All monuments, property lines, center lines of streets, alleys and easements, adjoining or within the tract, shall be tied into the survey.
(Ord. 430 § 5(d), 1950)
shall be defined as consisting of either:
(Ord. 430 § 5(e), 1950)
All monuments shall have a copper plate or disk, securely attached to the top of the monument by a copper dowel or nail not less than two and one-half inches long firmly embedded in concrete and marking the exact point. The registered license number of the engineer or surveyor shall be stamped upon the copper plate or disk.
(Ord. 430 § 5(f), 1950)
In making the survey, the engineer or surveyor shall set monuments in such a manner that the property lines may be retraced in any area of the subdivision with a minimum of difficulty without the necessity of retracing more than one block. He shall also show all tie-in reference datum to prior existing monuments and surveys of record with traceable record data.
(Ord. 430 § 5(g), 1950)
Where the exterior boundaries of the subdivision are existing street lines, on all interior street lines of the subdivision the engineer or surveyor shall set monuments in the street area, preferably on the street center line, and located so as to determine the street lines bounding each block. Due consideration shall be given to visibility of monuments, one from another, for the purpose intended.
(Ord. 430 § 5(h), 1950)
The monuments in the street areas shall be set so that the tops are at least seven and one-half inches below top of finished pavement grade and enclosed in cast iron receptacles, with cast iron covers of a type acceptable to the City Engineer set flush with the top of finished pavement grade and supported independently of the monuments.
(Ord. 430 § 5(i), 1950)
Monuments may be set after approval of the final map, but not later than the time of completion of subdivision improvements, provided a cash deposit or approved bond in an amount set by the City Engineer is filed with the City, guaranteeing such work.
(Ord. 430 § 5(j), 1950)
All monuments and their location shall be inspected and approved by the City Engineer.
(Ord. 430 § 5(k), 1950)
Redwood hubs, each two inches square in cross section and not less than 12 inches in length, shall be driven flush with the surface of the ground at all lot corners, angle points and curve points where no monuments are set and in each case the exact corner shall be marked by a nonferrous metal tack.
(Ord. 430 § 5(l), 1950)
