Parts "A" through "K" of this section apply to both public and private streets. A. Alignment and location. In adjoining subdivisions, streets shall be designed to: (1) conform to the alignment of existing adjoining streets; (2) where the adjoining land is not subdivided, streets shall be designed to conform to the projections of existing streets; (3) where physical conditions are conducive and reflect the City's overall grid pattern; (4) allow, as much as possible, for the subdivision of all adjoining unsubdivided land, and the Planning Commission may require that streets or parts of streets be provided to facilitate the subdivision of adjoining property. B. Rights-of-way and improvements. Except where a modification is expressly authorized in accordance with Chapter 18.230 Modifications, where a special cross section is required to conform with a specific plan or planned street line, or where the proposed street is private, street rights-of-way and the locations of improvements therein shall conform with the standards prescribed in Table 1 below. Table 1 STREET RIGHT-OF-WAY AND IMPROVEMENTS Right-of-way 10 | Median 1 | Pavement Width 2 | Curbs and Gutters | Parkway 3 Street Type | (ft.) | (ft.) | (ft.) | (ft.)

Includes width of curbs on both sides of median strip. 2. Measured from curb face to curb face. 3. Sidewalks shall be required at all locations unless specifically approved to be omitted. Sidewalks generally shall be located adjacent to the property line, except where findings can be made that there are unusual circumstances warranting location of a sidewalk adjacent to the street. All sidewalks shall be in accordance with Standard Drawing No. 325. The remaining parkway area shall be landscaped and irrigated as approved. 4. When approved because of short length, topography or other reasons. 5. Includes two feet of pavement within adjoining arterial right-of-way. 6. Forty-one feet of right-of-way where ultimate curb separation is 40 feet. Remaining parkway width is 13 feet. 7. Provides four travel lanes in each direction (excluding turning lanes, parking lanes and bike lanes). 8. Provides three travel lanes in each direction (excluding turning lanes, parking lanes and bike lanes). 9. Provides two travel lanes in each direction (excluding turning lanes, parking lanes and bike lanes). 10. Additional right-of-way may be required on arterial streets to accommodate reverse frontage configurations, scenic boulevard designations and additional traffic lanes at intersections. C. Curves and tangents. Street curves and tangents shall be as provided in this subsection, unless otherwise approved by the City Engineer. Curves on major and secondary streets shall have a centerline radius conforming to the specifications of the Public Works Department. Curves on collector streets shall have a centerline radius of not less than 300 feet. Curves on other streets shall have a centerline radius of not less than 200 feet. A tangent conforming with the Public Works Department's specifications shall be required between reverse curves on major, secondary and collector streets. D. Grades. Grades of streets shall be as provided in this subsection, unless otherwise approved by the City Engineer. Grades of streets shall be not less than four-tenths percent to ensure adequate drainage, and shall not exceed six percent on major, secondary and collector streets. Grades on other streets shall not exceed 12 percent. All breaks in grade should be joined by vertical curves of adequate length to provide safe sight distances and driving comfort. E. Intersections. The angle of intersection between public streets, between a public street and an alley, or between a public street and a private street shall be as nearly a right angle as topography and other limiting factors permit. F. Cul-de-sacs, dead-end streets and adjoining acreage. A cul-de-sac should not serve more than 16 lots, nor should it exceed 600 feet in length measured from the centerline of the intersection street to the center of the turnaround, except that a greater length may be permitted if warranted due to topographic or other specific conditions and if approved by the Public Works and Fire Departments. A turning area with a curbline radius of not less than 36 feet shall be provided at the end of such street. Alternate designs for turning or reversing directions may be permitted if approved by the Public Works Department. G. Where a street is terminated adjoining property capable of future subdivision, a one-foot-wide nonaccess barrier strip the width of the street right-of-way shall be dedicated to the City and accepted for public use to deny access from the adjoining property to the street. Future acceptance of the barrier strip by the City for street purposes shall be contingent upon the improvement of the strip and the extension of the street into the adjoining property. In addition, a barricade constructed in conformance with the specifications of the Public Works Department and/or a temporary turning area or temporary connection to another street shall be required. H. Frontage roads are normally discouraged. I. Limitations. A frontage road, or reverse frontage lots, side-on lots, or other type of limited access design may be required where land adjoins or fronts on a major or secondary street. To accomplish the purposes of this subsection, waivers of vehicular and pedestrian access rights to the major or secondary street may be required. Intersections of a frontage road with the street on which it borders shall be spaced so that minimum disruption of traffic results. At intersections, the planting strip separating the frontage road from the major or secondary street shall have sufficient depth to provide at least 40 feet of stacking space for vehicles entering the intersections between the frontage road and the major or secondary street to the specifications of the Public Works Department. J. Railroads, canals, and other grade crossings. Where a development borders on or contains a railroad right-of-way, canal, or other grade crossing, a street approximately parallel to such right-of-way at a distance suitable for the appropriate use of the intervening land may be required. Such distance shall be determined with due regard for traffic needs and the requirements of approach grades and future grade separations. Where the design of the development incorporates a street that borders a railroad or canal, the developer shall be required to install full width street improvements. K. Half streets. Half streets shall not be approved except where essential to the reasonable development of the subdivision in conformity with the requirements of this title and where the Planning Commission finds it will be practical to require the dedication of the remaining portion of the street when the adjoining property is subdivided. L. Access streets. A subdivision should be accessible by way of two or more improved streets with a minimum of 28 feet of pavement to the specifications of the Public Works Department. M. Street names. Streets that are a prolongation or approximate prolongation of existing streets shall be given the same names as the existing streets.
