A. The public street and highway design shall conform both in width and alignment with any general plan circulation element, precise street plans and other precise plans adopted by the City Council, and right-of-way for any such street or highway indicated on the general plan or precise plans shall be dedicated to the city by the subdivider.
B. Streets and highways not otherwise designated on the Circulation Element of the General Plan shall not be less than those set forth in this title; except where it can be shown by the subdivider that the topography of the land is such as to justify narrower width. Increased widths may be required for bicycle lanes or transit stops when determined necessary by the Planning Commission in the public interest. Approval or determination of street classification shall be made by the City Council by adopting improvement standards for:
Divided arterial streets
Undivided arterial streets
Collector streets/local streets
Minor loop streets
Cul-de-sac streets
Frontage road
C. Relationship to Existing Streets. The street system in the proposed subdivision shall relate functionally to the existing streets in the area adjoining the subdivision.
D. Centerlines. The centerlines of all streets, wherever practicable, shall be the continuations of the centerlines of existing streets or shall be offset at least one hundred fifty (150) feet.
E. Intersections. Each street intersection shall be as near to a right angle as is practicable, and no intersection of streets at angles less than sixty (60) degrees shall be approved unless necessitated by topographical conditions as determined by the city engineer.
F. Corners. At street intersections, the block corners shall be angled to provide sufficient right-of-way, and shall correspond to approved develop improvement standards.
G. Cul-de-sacs or Dead End Streets. No cul-de-sac or dead end street shall be more than eight hundred (800) feet in length. Where necessary to give access to or permit a satisfactory future development of adjoining land, streets shall extend to the boundary of the property and the resulting dead-end streets may be approved with a temporary turn-around. In all other cases, a turn-around having a minimum radius of fifty-three (53) feet, measured to the property line, and a minimum of forty-three (43) feet to curb face shall be required.
H. Curve Radius. The centerline curve radius on arterial streets shall be designed in accordance with acceptable safe engineering practices and in no case shall be less than five hundred (500) feet. Centerline curve radius on other streets shall not be less than two hundred (200) feet.
I. Frontage Streets. When any lot fronts or sides on any arterial street, expressway, or freeway, the subdivider may be required to dedicate and improve a frontage street to provide ingress to and egress from such lots.
J. Private Road and Alleys. Private roads and alleys shall not be permitted unless approved by the Planning Commission.
K. Grades. Grades of streets shall not be less than two-tenths (0.2) percent and not greater than seven (7) percent unless, because of topographical conditions or other exceptional conditions, the city engineer determines that a grade less than two-tenths (0.2) percent or in excess of seven (7) percent is necessary.
L. Access on Arterials. When the rear of any lot borders an arterial, the subdivider may be required to execute and deliver to the city an instrument prohibiting the right of ingress and egress from said arterial to said lot. (Ord. 2017-01 (part), 2017: prior code § 9045)
