PART 5. DESIGN
Sections:
§ 9205.2 Highways – Conformity with General Plan.
§ 9205.3 Major and Secondary Highways – Alignment.
§ 9205.4 Major and Secondary Highways – Widths.
§ 9205.5 Street Alignment and Grade.
§ 9205.6 Streets and Alleys – Right-of-Way and Roadway Widths.
§ 9205.7 Future Streets and Alleys.
§ 9205.8 Alleys/Service Roads.
§ 9205.9 Cul-de-Sac Streets and Dead-End Alleys.
§ 9205.10 Right-of-Way Corner.
9205.1 Access.
Access to a division of land shall be by means of an improved public street or highway having a minimum access width as required by the Zoning Ordinance.
9205.2 Highways – Conformity with General Plan.
If the General Plan shows a highway so located that any portion thereof lies within a division of land, that portion of the highway which is within the division shall be included in the design of the division unless the Advisory Agency determines that there is a reasonable probability that the General Plan will be amended to remove or relocate the highway so that it is no longer within the division of land.
9205.3 Major and Secondary Highways – Alignment.
If a centerline has been established for a highway, the alignment of the highway shall conform to the established centerline. If no centerline has been established, the alignment shall be substantially as shown in the General Plan. The centerline curve radius of a major highway shall be not less than one thousand five hundred (1,500) feet. The centerline curve radius of a secondary highway shall be not less than one thousand (1,000) feet. Highways shall intersect with streets and other highways as nearly at a right angle as is practical. No highway shall have a grade of more than six (6) percent nor less than four-tenths (0.4) of one (1) percent. If in the opinion of the Director of Public Works, topographical conditions do not permit in meeting the minimum grade requirements, this will necessitate the installation of additional catch basin inlets and/or extra width gutters, as determined by the Director of Public Works and his advisory agents.
9205.4 Major and Secondary Highways – Widths.
Major highways shall have a width of one hundred (100) feet and eighty-four (84) feet between curbs and secondary highways shall have a width of eighty (80) feet and sixty-four (64) feet between curbs, unless a different width is indicated in the General Plan, or where it is necessary to match existing highway widths which differ as determined by the Advisory Agency.
9205.5 Street Alignment and Grade.
The alignment of streets shall be such as to provide at least fifty (50) feet of frontage for each lot in the division of land, at least forty (40) feet of frontage for each lot abutting the cul-de-sac portion of a street, and, where necessary, to provide for the future development of adjacent properties.
Centerline jogs of one hundred fifty (150) feet or less for left hand vehicle turning configurations and centerline jogs of four hundred (400) feet or less for right hand vehicle turning configurations shall be avoided wherever practical.
On any street, no centerline curve radius of less than two hundred (200) feet shall be provided. A centerline having an arc length of less than one hundred (100) feet shall not be permitted unless the centerline radius is greater than three thousand (3,000) feet. Streets shall intersect with other streets and highways as nearly at a right angle as practicable. No street shall have a grade of less than four-tenths (0.4) of one (1) percent nor more than ten (10) percent. If in the opinion of the Director of Public Works, topographical conditions do not permit in meeting the minimum grade requirements, this will necessitate the installation of additional catch basin inlets and/or extra width gutters, as determined by the Director of Public Works and his advisory agents.
9205.6 Streets and Alleys – Right-of-Way and Roadway Widths.
Streets and alleys shall have the following minimum right-of-way and roadway widths:
a. Residential entrance streets from General Plan highways, through collector streets, streets adjacent to schools, and multiple residential use streets:
b. Interior collector and local streets, cul-de-sac streets, and loop streets:
c. Industrial and commercial streets – entrance or collector:
d. Industrial and commercial – cul-de-sac or loop:
e. Alley:
f. Industrial and commercial – existing street:
*Full width sidewalks may be required by the General Plan.
9205.7 Future Streets and Alleys.
The Advisory Agency may require that future streets and alleys be provided for the future division of lots shown on the tentative map and for the development of adjoining property.
9205.8 Alleys/Service Roads.
The Advisory Agency may require that an alley/service road be provided at the rear of lots which are intended for multiple residential (not including two-family use), commercial, or industrial use.
9205.9 Cul-de-Sac Streets and Dead-End Alleys.
An adequate turning area conforming to the specifications of the Director of Public Works shall be provided at the end of cul-de-sac streets and dead-end alleys.
9205.10 Right-of-Way Corner.
Intersections of road right-of-way lines, where one (1) or both streets are local residential, shall be rounded with a curve having a radius of thirteen (13) feet unless otherwise determined by the Director of Public Works.
Intersections of road right-of-way lines where both streets are highways or one (1) of the streets serves a commercial or industrial development, shall be rounded with a curve having a radius of twenty-seven (27) feet, unless otherwise determined by the Director of Public Works.
9205.11 Lot Design.
a. Each lot in a division of land shall have the required area and the required width as defined in the Zoning Ordinance. Where said Zoning Ordinance does not establish a required area and/or width in a particular zone, the required area shall be five thousand (5,000) square feet and the required width shall be fifty (50) feet. Strips of land intended for use as vehicular access shall not be included in calculating average width or required area.
b. If a lot is in more than one (1) zone, then the area and width thereof shall be not less than the area and width requirements, respectively, in that zone in which any part of the lot is located which has the largest area requirement and in that zone in which any part of the lot is located which has the greatest width requirement.
c. This Section does not apply to any lot which the subdivider offers to deed or dedicate to the public.
d. Where public sewers are not available and private sewage disposal is to be used, every lot or parcel or building site shall be of sufficient size to provide for satisfactory sewage disposal for land use intended.
e. In all cases where practical, the sidelines of lots shall be at an approximate right angle to the street upon which such lots front.
f. Wherever practical, divisions of property abutting rights-of-way for freeways, highways, railroads, transmission lines, and flood control channels shall be designed so as to create lots which back up to said right-of-way.
g. The Advisory Agency may determine that, by reason of circumstances peculiar to the proposed subdivision for the use proposed to be made of the property in the subdivision, the public peace, health, safety, and welfare will be protected adequately by lots of lesser frontage or area than that specified in this Section.
h. This Section applies only to future divisions of land within the City and shall not be deemed to limit the existing requirements imposed under the Zoning Ordinance as to lots already subdivided.
9205.12 City Boundary.
No lot shall be divided by a City boundary line. Each such boundary line shall be made a lot line.
