   (B)   Major thoroughfares (designated as expressways or arterials in the circulation element of the general plan) shall be not less than 100 feet wide.
   (C)   Secondary thoroughfares (designated as arterials or collectors in the circulation element of the general plan) shall be not less than 80 feet wide.
   (D)   Local collector streets (designated as collectors or local streets in the circulation element of the general plan) shall not be less than 60 feet wide.
   (E)   Minor and cul-de-sac streets shall be not less than 50 feet wide. The radius at the terminus of the cul-de-sac should be not less than 47 feet at the curb, and shall be paved.
   (F)   Special local streets where railroads, parkways, grade separation, freeways and hills, or other dominant factors are involved shall be subject to individual determination by the city.
   (G)   Along major highways or limited-access highways, a service roadway separated from the main traffic roadway by an appropriate separation strip may be required, which service roadway will provide for access to abutting lands and to other public streets. Along major highways an alley or alleys may be required in lieu of the service road or roads as a facility for serving lands marginal to the major highways.
   (H)   Curved major highways shall have a center line radius of not less than 1,000 feet.
   (I)   Curved secondary streets shall have a center line radius of not less than 500 feet.
   (J)   Curves on other streets shall have a center line radius of not less than 100 feet.
   (K)   Street corners shall have a radius of not less than 15 feet at property line returns and not less than 25 feet at curb line returns.
   (L)   Street intersections shall be as near right angles as practicable. In no case shall the angle be less than 45 degrees.
   (M)   Streets which are a continuation of streets in contiguous territory shall be so aligned as to assure that their center lines shall coincide. In cases where straight continuations are not physically possible, the center line shall be continued by curves.
   (N)   In areas where no specific plan exists, the layout of all improvements including, but not limited to, roadways, curbs, parkways, dividing strips, sidewalks, sewer lines and water mains within the rights-of-way of all highways, streets, alleys and utilities easements shall be in accordance with the standards established by the City Council, and where no standards have been adopted, the arrangements shall be subject to approval by the city.
   (O)   Unless otherwise provided by the advisory agency, all streets must have a minimum width of one-half the roadway plus 11 feet. The last foot of any part width street shall be designated on the subdivision map as restricted access strip, separating the road from adjoining land which is not in the subdivision and thereby limiting the approach of the adjoining land. The restricted access strip shall be offered for dedication to the city for road purposes.
