16.11.020 Street Grades.
No highway or street shall have a grade of more than six percent (6%), except for short stretches where the topography makes it impractical to keep within such grade, and in no event shall the grade exceed ten percent (10%) except where evidence, which is satisfactory to the approving authority, is given that a lower grade is not possible. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.030 Right-of-Way.
Intersections of road right-of-way lines where one (1) 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 General Plan Circulation Map Joint Highway Plan, or one (1) 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. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.040 Future Streets.
Wherever the approving authority 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 approving authority may require that the location, width and extent of such street shall be shown on the final map or final parcel map as a future street. No improvement of such future street shall be required of the subdivider. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
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 three hundred fifty (350) feet 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. 13-8 § 4 (Exh. A), 6/11/13)
16.11.060 Street Intersection Angle.
Except as provided in Section 16.09.020 (Conformity with General Plan Circulation Map Joint Highway Plan), 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 (Conformity with General Plan Circulation Map Joint Highway Plan), 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. 13-8 § 4 (Exh. A), 6/11/13)
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 as determined by the City Engineer.
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 approving authority finds such alley inadvisable, undesirable, detrimental to adjoining property or contrary to the best community design. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.080 Alleys in Congested Districts.
The approving authority 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 (2) family use) or commercial, industrial, mixed use or other less-restrictive uses. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
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 unless modifications are required by the City Engineer. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.100 Turnarounds.
A. A turning area shall be provided at the end of cul-de-sac streets and dead-end alleys. The approving authority 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.
B. All such turnarounds shall conform to the specifications of the City Engineer and the Fire Department. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
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. Six hundred (600) feet in length, when serving land zoned for residential uses having a density of more than two (2) dwelling units per net acre;
3. One thousand (1,000) feet in length, when serving land zoned for residential uses having a density of two (2) 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 approving authority 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. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.120 Mobilehome Divisions of Land—Street and Driveway Standards.
Those streets, existing or proposed within or contiguous to a mobilehome 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 (Right-of-Way and Roadway Width Requirements—Cross-Section Diagrams). Driveways in such division shall have minimum widths of thirty (30) feet. However, greater driveway widths may be required by the approving authority if the design or magnitude of such division warrants the greater width or it is located in a very high fire hazard severity zone. (Ord. 13-8 § 4 (Exh. A), 6/11/13)
16.11.130 Fire-Fighting Access Easements.
In areas where, in the opinion of the Fire Department, there will be fire hazard to the watershed for any other properties and/or is located in a designated very high fire hazard severity zone, 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 Fire Department advises that this condition will impair the provision of adequate fire protection, the approving authority 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 Fire Department shall make recommendations to the approving authority 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 approving authority. (Ord. 13-8 § 4 (Exhs. A, D), 6/11/13)
