§ 110-201. Streets.

(a)

Conformity to general plan. The arrangement, character, extent, width, grade and location of all streets in a subdivision shall conform to the general community plan and shall be considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety and in their appropriate relation to the proposed uses of the land to be served by such streets.

(b)

Arrangement when not shown on general plan. Where such is not shown in the general community plan, the arrangement of streets in a subdivision shall either:

(1)

Provide for the continuation or appropriate projection of existing principal streets in surrounding areas; or

(2)

Conform to a plan for the neighborhood approved or adopted by the planning and zoning board to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impracticable.

(c)

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

(d)

Subdivisions abutting arterial streets. Where a subdivision abuts or contains an existing or proposed arterial street, the planning and zoning board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear service alleys, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.

(e)

Subdivisions bordering on, containing railroad or limited access highway. Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, the planning and zoning board may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for commercial or industrial purposes in appropriate districts. Distances involving right-of-way shall also be determined with due regard for the requirements of approach grades and future grade separations.

(f)

Reserve strips. Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the city under conditions approved by the planning and zoning board.

(g)

Street jogs. Street jogs with centerline offsets of less than 125 feet shall be avoided.

(h)

Tangent between reverse curves. A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.

(i)

Curve connecting streets. 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 of not less than 150 feet for minor and collector streets, and of such greater radii as the planning and zoning board shall determine for special cases.

(j)

Intersections. Streets shall be laid out so as to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 60 degrees.

(k)

Property lines at intersections. Property lines at street intersections shall be rounded with a radius of ten feet, or of a greater radius where the planning and zoning board may deem it necessary. The planning and zoning board may permit comparable cutoffs or chords in place of rounded corners.

(l)

Right-of-way widths. Street right-of-way widths shall be as shown in the general community plan and where not shown therein shall be not less than as follows:

Street Type	Right-of-Way Width (feet)
Arterial	80
Collector	65
Minor	50
Pedestrian and service easement	12

 

(m)

Half streets. Half streets shall be prohibited, except where essential to the reasonable development of the subdivision in conformity with the other requirements of this chapter, and where the planning and zoning board finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided. Wherever a half street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.

(n)

Dead ends. Dead-end streets, designed to be so permanently, shall not be longer than 500 feet and shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 80 feet, and a street property line diameter of at least 100 feet.

(o)

Names. No street names shall be used which will duplicate or be confused with the names of existing streets. Street names shall be subject to the approval of the planning and zoning board.

(p)

Grades. Street grades, wherever feasible, shall not exceed eight percent or be less than two-tenths of one percent.
