Every parcel of land hereafter used as a parking area shall be designed and maintained in accordance with the following requirements:
(a) Off-street parking areas shall be of useable shape and surface, and shall have convenient ingress and egress. Not less than seventy-five percent (75%) of the total provided parking spaces shall be designed for use by full-size vehicles. Up to twenty-five percent (25%) of the provided parking may be designed and designated for compact vehicles. Aisles and access drives shall be designed so as to provide adequate vehicular maneuvering wholly upon the property being served; and in no case shall off-street parking areas be permitted that encourage or require the backing onto, or maneuvering within, the right-of-way of any public or private street.
(b) Any lighting used to illuminate off-street parking areas shall be regulated by Article 30.
(c) Any off-street parking area having more than one thousand, eight hundred (1,800) square feet of area and/or used by five (5) or more vehicles shall be landscaped and screened as required by Article 18, Landscape and Land Use Buffers.
(d) A "sight triangle" shall be observed at all street intersections or intersections of driveways with streets as required in Article 18, Landscape and Land Use Buffers and Section 3-3 of this Zoning Ordinance.
(e) All parking areas shall be paved and drained so as to dispose of all surface water within the parking area without carrying said water accumulation over a public sidewalk. Piping the water to a suitable outfall may be required.
(f) The parking area and driveway shall be paved with concrete, asphalt, brick, grass pavers, or other suitable hard surface materials as approved by the Division of Building Inspection.
Loose aggregate or other type of gravel is prohibited, except:
(i) for agricultural land uses;
(ii) as approved by the Board of Architectural Review for the purpose of historic preservation; or
(iii) when approved by the Urban County Forester for the purpose of tree protection.
In any case, the applicant must show that there is not another reasonable alternative to the loose aggregate. Where decorative rock, or a similar product, is being driven on or being used for parking, it shall be considered loose aggregate and prohibited, except where described in this section.
(g) Permanent stormwater management, in compliance with the stormwater manuals and accepted by the Division of Engineering, shall be provided for all off-street parking areas containing five (5) or more parking spaces and/or more than one thousand, eight hundred (1,800) square feet. For off-street parking areas of one thousand, eight hundred (1,800) square feet or less, or less than five (5) parking spaces, permanent stormwater retention may be required by the Division of Engineering upon the determination that the lack of such retention would cause or aggravate flooding or other drainage problems on surrounding property.
