§ 56-478. Interchange development standards.

The purpose of this section is to provide realistic controls for assuring safe and convenient access to the development of properties that adjoin interchanges and discourage the indiscriminate location of access points along the intersecting highway.

(1)

Area of control. The following interchange development standards shall apply to all business, residential and industrial development within a radius of one-half mile of the interchange structure except where the area of control extends inside the corporate limits of a municipality that is not subject to the regulations of this chapter. Provisions of the C4, R3 and I3 districts shall apply to all business, residential and industrial development within the specified area of control.

(2)

Setback distance from intersecting highway. Buildings and structures shall be set back at least 80 feet from the right-of-way line of intersecting highways and 100 feet from the interstate freeway right-of-way. In case of usual changes in alignment of the highway right-of-way line or unusual topographic conditions which would cause undue hardship in the application of this requirement, a variance for a lesser setback distance from the intersecting highway may be granted by the board.

(3)

Limitation of access.

a.

The state department of transportation has developed access regulations for each particular interchange based on ramp design and ramp speed. These regulations shall apply only when they are more restrictive than the following regulations.

b.

Access from abutting property to an intersecting highway shall be permitted only at points of access existing prior to the adoption of the ordinance from which this chapter is derived, or future access points shall be located as follows:

1.

There shall be no access points located within 700 feet of the most remote end of taper of any existing or proposed entrance or exit ramp of an interchange or at intervals of less than 700 feet thereafter. A lesser distance may be permitted by the board upon prior written approval by the state department of transportation or the agency having jurisdiction over the intersecting highway.

2.

To avoid dangerous off-set intersections, public streets along opposite sides of intersecting highways shall be located either directly opposite each other or directly opposite a median strip crossover, or separated by at least 300 feet of lateral distance. A lesser distance may be permitted by the board upon prior written approval by the state department of transportation or the agency having jurisdiction over the intersecting highway.

3.

Access and site planning principals to be applied are illustrated on Figure 7.
