Chapter 16.24
STREETS
Sections:
16.24.080 Right-of-way widths.
16.24.010 Arterials.
Wherever a subdivision embraces an arterial street, as shown on the major street plan, such arterial street shall be platted in the location and of the width required by the city. (Ord. 1161 §1(part), 1984).
16.24.020 Layout.
The street layout shall be devised for the most advantageous development of the entire neighborhood area. Where necessary to the neighborhood pattern, existing principal streets in adjoining subdivision shall be continued and shall be at least as wide as such existing streets and in alignment with them. The street layout shall provide for the future projection for the principal streets into unsubdivided lands adjoining. (Ord. 1161 §1(part), 1984).
16.24.030 Minor.
Minor streets shall be so laid out that their use by through traffic will be discouraged. (Ord. 1161 §1(part), 1984).
16.24.040 Alleys.
Paved rear alleys not less than twenty feet wide will be required in all business and industrial districts of subdivisions except where special conditions make alleys impracticable; in such cases, adequate off-street loading space, suitably surfaced, shall be provided. Dead-end alleys shall be avoided whenever possible, or if provided, shall include a turnaround. In general, alleys will not be approved for residential districts or subdivisions. (Ord. 1161 §1(part), 1984).
16.24.050 Half.
Half streets shall be permitted only under exceptional circumstances. (Ord. 1161 §1(part), 1984).
16.24.060 Grades.
Street grades shall conform in general to the terrain and shall not be less than one-half of one percent nor more than eleven percent. Street grades shall be such as to provide natural surface drainage of stormwater regardless of the presence or absence of storm sewers. The intent of this section is to avoid depressions or inverts which will flood in flash storms and for which storm sewers are inadequate. (Ord. 1161 §1(part), 1984).
16.24.070 Cul-de-sacs.
Cul-de-sacs shall not exceed four hundred feet in length and whenever possible, the closed end shall be located at a higher elevation than the entrance, and shall have a turnaround not less than ninety feet in diameter of right-of-way and pavement diameter of seventy feet at the closed end. (Ord. 1161 §1(part), 1984).
16.24.080 Right-of-way widths.
Right-of-way widths shall be as follows:
A. Arterial, eighty feet;
B. Secondary arterial, sixty feet; and
C. Minor street, fifty feet. (Ord. 1161 §1(part), 1984).
16.24.090 Roadway widths.
Minimum roadway widths (curb-to-curb) shall be as follows:
A. Arterial, fifty feet;
B. Secondary arterial, forty feet; and
C. Minor streets, thirty-two feet. (Ord. 1161 §1(part), 1984).
16.24.100 Curvature.
Minimum curvature of streets shall be as follows:
A. Arterial, six-hundred-foot radius;
B. Secondary arterial, two-hundred-foot radius;
C. Minor street, one-hundred-foot radius. (Ord. 1161 §1(part), 1984).
16.24.110 Intersections.
A. There shall be a minimum number of intersections of minor streets with major streets and in the case of intersecting minor streets, intersections of four streets shall be avoided whenever possible.
B. Street intersections shall be at right angles. Where, because of topographic or other reasons, an intersection cannot be at right angles, such intersection shall be designed so as to insure its safe usage. (Ord. 1161 §1(part), 1984).
16.24.120 Curb radii.
Curb radii shall not be less than twenty feet. Where an angle of intersection less than seventy degrees is permitted, curb radii shall be increased as necessary so as to insure its safe usage. (Ord. 1161 §1(part), 1984).
