(A) Design. The design, layout, width, circulation, and other design aspects of the streets in a subdivision shall conform to the locations and roadway sections which may have been adopted into the Circulation Element of the General Plan and/or Select System of Streets and in all cases shall be in general conformity with the advantageous develop-ment of the area within which the subdivision lies.
(B) Reserve strips. Reserve strips controlling the access to streets or other public rights-of-way shall not be approved unless such strips are necessary for the protection of the public welfare or substantial property rights. Reserve strips shall not be approved unless the control and disposal of the land comprising such strips are placed with the city under conditions approved by the Commission.
(C) Intersections. All streets shall intersect as nearly as possible at right angles.
(D) Center lines. Streets entering upon opposite sides of any given street shall have their center lines directly opposite each other, or such center lines shall be offset by at least 200 feet.
(E) Distance between certain streets. The mini-mum distance between streets entering a thoroughfare shall be 800 feet where feasible.
(F) Planting areas and parks. Where a subdivider proposes the creation of planting areas, parks, parked streets, or other parcels of land to be used for subdivision owners or for the public, the approval of such areas shall be conditioned upon adequate provisions for the maintenance of such areas until such time as the maintenance is assumed by a public agency.
(G) Street names. Street names shall be subject to the approval of the Commission.
(H) Rights-of-way and similar facilities. If a subdivision borders on or contains a railroad right-of-way, a limited access freeway, or similar type of facility, the Commission may require the street plan be considered in its relation to the probability of grade separation.

(A) The streets in subdivisions shall be classified by the City Engineer in accordance with their importance in community development, importance for local circulation, and the volume and type of traffic expected to be carried, which consideration shall not be limited to the number of lots fronting directly on the street.
(B) The classes of streets shall be designated as follows:
(1) Thoroughfares or arterials;
(2) Collector streets;
(3) Local streets; and
(4) Hillside streets.
('66 Code, § 9-4.608) (Ord. 275-C-S, passed 3-11-75)
(A) Roadbed. The structural design of the road-bed shall include the determination of the thickness of the subbase, base, and asphalt surfacing to be placed over the basement soil according to an accepted engineering method.
(B) City Engineer specifications. The City Engineer shall specify the structural design for the streets.
(C) Soil tests. The subdivider may, at his sole expense, make preliminary tests of the soil over which the surfacing and base is to be constructed and furnish the test reports to the City Engineer for use in determining a preliminary structural design of the roadbed. After the rough grading has been completed, the City Engineer shall have tests performed, at the subdivider's expense, to determine the final structural design of the roadbed.
(D) Thickness of materials. In no case shall the thickness of the base material be less than six inches, nor shall the thickness of asphalt concrete surfacing be less than two inches.
('66 Code, § 9-4.609) (Ord. 275-C-S, passed 3-11-75) Penalty, see § 9-4.903
Street widths shall be in accordance with the typical street sections indicated in the Circulation Element of the General Plan.
('66 Code, § 9-4.610) (Ord. 275-C-S, passed 3-11-75) Penalty, see § 9-4.903
(A) Maximum street grades shall not exceed the following limits:
(1) For major arterials, 6%;
(2) For collector streets, 10%; and
(3) For local streets, 15%.
(B) The minimum uniform grade for all classes of streets shall not be less than 0.75%.
(C) The grade of the pavement surface across an intersection shall not be more than 6%.
(D) The gradient of each street entering an intersection shall not be more than 6% within a distance of 30 feet from the near curb line of the crossing street.
(E) Changes of grade in the vertical alignment of the streets shall be made with parabolic vertical curves. The length of the vertical curves required shall be determined by the following conditions:
Minimum
Stopping
Sight Distance | Maximum Rate of Change in Grade for Crest Vertical Curves | |
Major arterial streets | 350 ft. | 1.2% per 100 feet |
Collector streets | 200 ft. | 4% per 100 feet |
Local streets | 100 ft. | 10% per 100 feet |
(F) (1) The headlight sight distance, as determined in accordance with the standards of the State Department of Transportation for sag vertical curves, shall not be less than those listed in division (E) of this section for minimum stopping sight distances.
(2)
STOPPING SIGHT DISTANCES shall be those distances at which an object on the pavement, six inches in height, can be seen from another point three feet nine inches above the pavement surface.
(G) The minimum length of vertical curves shall be 50 feet for minor streets, 100 feet for collector streets, and 200 feet for major arterials.
('66 Code, § 9-4.611) (Ord. 275-C-S, passed 3-11-75) Penalty, see § 9-4.903
(A) Changes in the direction of streets shall be made with horizontal circular curves with the edges of the pavement and curb lines parallel to and equidistant from the center lines of the rights-of-way.
(B) The radius of curvature in the center lines of streets shall be not less than the following:
(1) For major arterial streets, 650 feet;
(2) For collector streets, 200 feet:
(3) For local streets, 100 feet; and
(4) For hillside streets, 75 feet.
('66 Code, § 9-4.612) (Ord. 275-C-S, passed 3-11-75) Penalty, see § 9-4.903
