All plats must conform to the following street design standards:

1.

Conformance. The arrangement, extent, width, grade and location of all streets shall conform to the master plan and shall be considered in their relation to existing and planned streets, topographical conditions, to public conveniences and safety and in their appropriate relation to the proposed uses of the land to be served by such streets. Where not shown in the master plan, the arrangement and the other design standards of streets shall conform to the provisions found in this section.

2.

Relation to adjoining street system. The arrangement of streets in new subdivisions shall make provisions for the continuation of existing streets in adjoining areas.

3.

Projection of street. Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall make provisions for the proper projection of streets.

4.

Streets to be carried to property lines. When a new subdivision adjoins unsubdivided land, then the new streets shall be carried to the boundaries of the tract proposed to be subdivided where required to promote reasonable development of the adjacent lands or provide continuity of road systems.

5.

Street jogs. Street jogs with centerline offsets of less than 125 feet shall be prohibited unless, because of unusual conditions, the plat division determines that a lesser centerline offset is justified.

6.

Dead-end streets or cul-de-sacs. Dead-end streets or cul-de-sacs designed to be so permanently, shall not be longer than 600 feet, and at the closed end, a turnaround having an outside roadway diameter of at least 84 feet, and a street property line diameter of at least 100 feet, may be required. If a dead-end street is of a temporary nature, a similar turnaround may be required, and provisions made for future extension of street into adjoining property, as may be required by the city engineer.

7.

Marginal access streets. Where a subdivision abuts or contains an existing limited access highway or arterial street, marginal access streets, or other such treatment as may be necessary for adequate protection of residential property and to afford separation of through and local traffic, may be required.

8.

Minor streets. Minor streets shall be so laid out that their use by through traffic shall be discouraged.

9.

Railroad on or abutting subdivision. Where a subdivision borders on or contains a railroad right-of-way, a street approximately parallel to and on each side of such right-of-way may be required, at a distance suitable for the appropriate use of the intervening land for park purposes in residential districts or for commercial or industrial purposes in appropriate districts. Such distances shall be determined with due regard for the requirements of approach grade and future grade separation in accordance with uniform standards prescribed by the city engineer.

10.

Tangents. A tangent of at least 100 feet long shall be introduced between reversed curves on arterial and collector streets.

11.

Deflection of connecting street lines. When connecting street lines deflect from each other at any one point by more than ten degrees, they shall be connected by a curve with a radius adequate to ensure a sight distance and safe turning movement in accordance with uniform standards prescribed by the city engineer.

12.

Right-angle intersections. Streets shall be laid out so as to intersect as nearly as possible at right angles.

13.

Rounding of property lines at intersections. Property lines at street intersection shall be rounded with a radius of 25 feet. A greater radius may be prescribed by the city engineer in special cases in accordance with uniform standards prescribed by applicable regulations. The city engineer may permit comparable cutoffs or chords in place of rounded corners.

14.

Right-of-way widths. Street right-of-way widths shall be as shown on the master plan or in the City's Code of Ordinances.

15.

Half streets. Half streets shall be prohibited, except where essential to the reasonable development of the subdivision in conformity with other requirements of this article, and where the city engineer finds it will be practical to require the dedication of the other half when adjoining property is subdivided. Whenever a half street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tracts.

16.

Names and numbers. No street names or numbers shall be used which will be confused with or duplicate the name of existing streets. Street names shall be subject to the approval of the city engineer.
