(b) Concrete monuments depressed below street grade, with cast iron ring and cover of a type approved by the city, shall be set at intersections of street center line tangents or offsets therefrom, and where such intersect on private property, at the beginning and end of the center line curve and/or offsets therefrom. The exact location of all such monuments shall be shown on the final map before approval is requested.
(c) Permanent elevation benchmarks of a type approved by the city and referred to the city datum shall be set at each street intersection in the curb return or other location approved by the city.

(3) Surface Drainage and Storm Sewer System. Drainage facilities shall be installed to provide drainage within the subdivision or partition and to connect the drainage to existing or future drainage ways or storm sewers outside the subdivision or partition.
