ARTICLE VI. DESIGN STANDARDS

DIVISION 2. STREETS AND ROADS

Sec. 20.5-98. Driveways and entrances.

(a) The minimum spacing between the tangent point of an intersection and permitted driveways or entrances, and between driveways or entrances themselves, shall be in accordance with the following table based on the street classification, provided, however, that a greater or lesser distance may be stipulated by the agent upon the recommendation of the department of transportation. Reduction of these spacing requirements shall be permitted when the property configuration or location would preclude strict application of these standards, provided however that where an alternate access arrangement or an internal access system is practical and feasible, multiple driveways or entrances not in conformance with these spacing standards shall not be permitted.

(b) The width of residential driveways shall be not less than nine feet (9') and not greater than twenty feet (20') measured at the edge of the right-of-way.

(c) Driveways or entrances to lots created adjacent to streets classified as major collector, minor arterial, or major arterial shall conform with the following standards:

(1) Where all of the lots I) front on a single roadway so classified, ii) extend the full depth of the parent tract and, iii) no further subdivision of those lots is possible, each two (2) abutting non-residential lots shall be permitted one (1) driveway or entrance access point which shall be identified and noted on the final and record plat as being the access for both non-residential lots. Each residential lot shall be entitled to an individual access. In all other cases, an internal access system shall be developed.

(2) Where any lots created are to front on or obtain access from an internal access system, such system shall be designed to provide the access to all lots. Access onto the above classified streets shall be permitted only where the internal access system intersects such streets.

(3) A restricted access easement ten feet (10') in width shall be shown on the final and record plat and be recorded along the entire frontage except at the above permitted access points.

(4) The agent may grant exceptions to these requirements with the concurrence of the department of transportation upon finding that:

a. The need for, and safety of, such additional access points has been substantiated in a traffic impact analysis prepared in accordance with article II, division 5 of the zoning ordinance to the satisfaction of the agent; and

b. All applicable spacing and clearance requirements as prescribed by this chapter, the zoning ordinance, and the department of transportation can be met.

(d) Except for single-family detached residential development, the use of shared access arrangements shall be the preferred alternative.
