16.11.010 Right-of-Way and Improvement Width Requirements—Cross-Section Diagrams.
Right-of-way and improvement widths shall conform to those established by City Council Resolution.
16.11.020 Street Grades.
No highway or street shall have a grade of more than six (6) percent, except for short stretches where the topography makes it impractical to keep within such grade, and in no event shall the grade exceed ten (10) percent except where evidence, which is satisfactory to the Planning Commission, is given that a lower grade is not possible.
16.11.030 Right-of-Way.
Intersections of road right-of-way lines where one or both roads are local residential shall be rounded with a curve having a radius of thirteen (13) feet, unless otherwise determined by the City Engineer. Intersections of road right-of-way lines, where both roads are shown as highways on the Master Plan of Arterial Highways or one of the roads serves a commercial or industrial development, shall be rounded with a curve having a radius of twenty-five (25) feet, unless otherwise determined by the City Engineer.
16.11.040 Future Streets.
Wherever the Planning Commission shall have determined that a street is necessary for the future division of property as shown on the tentative map, or for adjoining property, but that the present dedication and construction of such street is not warranted, the Planning Commission may require that the location, width and extent of such street shall be shown on the final map or parcel map as a future street. No improvement of such future street shall be required of the subdivider.
16.11.050 Centerline Curve Radius.
On any street the centerline curve radius shall not be less than one hundred (100) feet for streets having a pavement width of thirty-four (34) feet, two hundred fifty (250) feet radius for streets having a pavement width of thirty-six (36) feet and radius for streets having pavement width of forty (40) feet. A smaller radius may be approved where sufficient evidence is offered to the City Engineer by the subdivider to show that the specified radius is not practicable. (Ord. 00-3, 2/8/00)
16.11.060 Street Intersection Angle.
Except as provided in Section 16.09.020, any highway or street intersecting any other highway or street shall intersect it at an angle as nearly a right angle as practicable. Except as provided in Section 16.09.020, any highway or street shall intersect as nearly a right angle as practicable. The intersection centerlines shall not be more than ten (10) degrees from the right angle. (Ord. 00-3, 2/8/00)
16.11.070 Service Roads or Alleys Required.
A. Whenever it is proposed to divide property abutting a major or secondary highway, a service road or other local street shall be provided unless the circumstances of such property or of adjoining property render it inadvisable or undesirable to provide access by such service road or other local street.
B. Where a service road or local street is not required, the subdivider shall provide an alley at the rear of such lots unless the Planning Commission finds such alley inadvisable, undesirable, detrimental to adjoining property or contrary to the best community design.
16.11.080 Alleys in Congested Districts.
The Planning Commission may require that any alley be provided at the rear of all lots where property is to be used for multiple residential use (not including two-family use) or commercial or other less-restrictive uses.
16.11.090 Alley Intersections.
Where two (2) alleys intersect, a cutoff of not less than ten (10) feet along each alley shall be provided.
16.11.100 Turnarounds.
A. A turning area shall be provided at the end of cul-de-sac streets and dead-end alleys. The Planning Commission may require turnarounds:
1. Upon the recommendation of the City Engineer, at intermediate points on cul-de-sacs of more than seven hundred (700) feet in length, and on other local streets where the distance between intersections exceeds two thousand (2,000) feet; and
2. At the end of stub or dead-end streets of more than three hundred (300) feet in length where the future extension of the street is remote.
B. All such turnarounds shall conform to the specifications of the City Engineer.
16.11.110 Cul-De-Sacs—Length Restrictions.
A. Cul-de-sacs shall not be more than:
1. Five hundred (500) feet in length, when serving land zoned for industrial or commercial use;
2. Seven hundred (700) feet in length, when serving land zoned for residential uses having a density of more than four (4) dwelling units per net acre;
3. One thousand (1,000) feet in length, when serving land zoned for residential uses having a density of four (4) or less dwelling units per net acre.
B. This section shall not be construed to prohibit the approval of a division of land utilizing frontage on an existing cul-de-sac of more than the maximum permitted length nor shall it be construed to prohibit the Planning Commission from reducing the length of a proposed cul-de-sac to less than the maximum length permitted by this section or requiring the elimination of a proposed cul-de-sac in order to provide for the efficient circulation of traffic, the future development of the neighborhood street system or the deployment of emergency services.
16.11.120 Mobile Home Divisions of Land—Street and Driveway Standards.
Those streets, existing or proposed within or contiguous to a mobile home division of land which are to be dedicated or offered to be dedicated for public use, shall meet the standards outlined in Section 16.09.030. Driveways in such division shall have minimum widths of thirty (30) feet. However, greater driveway widths may be required by the Planning Commission if the design or magnitude of such division warrants the greater width.
16.11.130 Pedestrian Ways.
Excepting in the case of any reversion-to-acreage map, vacation map or boundary-line map, a transverse pedestrian way of adequate width may be required through the approximate middle of each block having a length of more than seven hundred (700) feet. No such pedestrian way shall have a grade exceeding thirty (30) percent; provided, that where one or more adequate stairways in any such pedestrian way are made a part of the improvement thereof, the grade of such stairway may be great as seventy-five (75) percent.
16.11.140 Fire-Fighting Access Easements.
In areas where, in the opinion of the Forester and Fire Warden, there will be fire hazard to the watershed for any other properties, unobstructed fire protection access easements, not less than fifteen (15) feet wide, shall be dedicated from the public highway to the boundary of the division of land. Where the design of a division of land will cause an existing fire road or fire break to be severed, and the Forester and Fire Warden advises that this condition will impair the provision of adequate fire protection, the Planning Commission may require that the subdivider either revise the design of the division of land so that the fire road or fire break will not be severed or provide an alternate easement. The Forester and Fire Warden shall recommend to the Planning Commission regarding the location, design and grading of easements required pursuant to the provisions of this section. Such location, design and grading shall be as found necessary by the Planning Commission.
