(Ord. 537 § 2 (part), 1985)

(a) If the circulation element of the general plan shows a highway so located that any portion thereof lies within a design unit, that portion of the highway which is within the design unit shall be included in the design of the division unless the city council 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 design unit.

(b) If the city council determines that the present acceptance and construction of a highway or portion thereof is not warranted, the highway or portion thereof shall be included in the design of the division of land as a future street.

(Ord. 537 § 2 (part), 1985)

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 conform to the following requirements:

(a) The alignment shall be substantially as shown on the circulation element of the general plan;

(b) The centerline curve radius of an arterial highway shall be not less than one thousand five hundred feet;

(c) The centerline curve radius of a collector highway shall be not less than one thousand feet;

(d) 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 percent nor less than four-tenths of one percent.

(Ord. 537 § 2 (part), 1985)

Arterial highways shall have a width of one hundred feet and collector highways shall have a width of eighty feet, unless a different width is indicated on the circulation element of the general plan.

(Ord. 537 § 2 (part), 1985)

The alignment of streets shall be such as to provide at least sixty feet of frontage for each lot in the design unit, except as specified in Section 11.24.140. Lots which abut arterial or collector highways, to which access rights are to be relinquished, shall be provided with frontage on a service road or other local street.

(a) Centerline jogs of one hundred fifty feet or less shall be avoided whenever practicable.

(b) On any street no centerline curve radius of less than two hundred feet shall be provided. A centerline having an arc length of less than one hundred feet shall not be permitted unless the centerline radius is greater than three thousand feet.

(c) Streets shall intersect with other streets and highways as nearly at a right angle as feasible.

(Ord. 537 § 2 (part), 1985)

No street shall have a grade of less than four-tenths of one percent nor more than ten percent except where the city council determines a grade not to exceed fifteen percent to be necessary due to topographic limitations.

(Ord. 537 § 2 (part), 1985)

All streets shall have a minimum right-of-way width of sixty feet and have an improved roadway width of thirty-six feet. All alleys shall have a minimum right-of-way of twenty feet improved full width. Dead-end alleys shall have a minimum turnaround of twenty-six feet improved to full width.

(Ord. 537 § 2 (part), 1985)

The city council 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.

(Ord. 537 § 2 (part), 1985)

(a) Cul-de-sacs shall be not more than:

(1) Five hundred feet in length, when serving land zoned for industrial or commercial use;

(2) Seven hundred feet in length, when serving land zoned for residential uses having a density of more than four dwelling units per net acre;

(3) One thousand feet in length, when serving land zoned for residential uses having a density of four 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.

(Ord. 537 § 2 (part), 1985)

(a) Intersections of road right-of-way lines, where one or both streets are local residential, shall be rounded with a curve having a radius of fifteen feet unless otherwise determined by the superintendent of streets.

Each lot shall have an average width of not less than the required width. Strips of land intended for use as vehicular access shall not be included in calculating average width or required area. The required area and the required width shall be the same as those terms are defined in the zoning ordinance. Where the zoning ordinance does not establish a required area and/or width in a particular zone, the required area shall be six thousand square feet and the required width shall be sixty feet.

(b) If a lot is in more than one 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) In all cases where practical, the sidelines of lots shall be at an approximate right angle to the street upon which such lots front.

(e) 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 rights-of-way.
