Whenever there is an alteration of a structure or a change or extension of a use which increases the parking requirements according to the standards specified in this Chapter, the total additional parking required for the structure or use, including the existing and additional alteration, change or extension, shall be provided in accordance with the requirements of that Section.

No parking area shall be used for any use that interferes with its availability for the parking need it is required to serve.

All required facilities shall be provided and maintained so long as the use exists which the facilities were designed to serve. Off-street parking facilities shall not be reduced in total extent after their provision, except upon the approval of the Zoning Hearing Board and then only after proof that, by reason of diminution in floor area, seating area, the number of employees or change in other factors controlling the regulation of the number of parking spaces, such reduction is in conformity with the requirements of this Part 10. Reasonable precautions shall be taken by the owner or sponsor of particular uses to assure the availability of required facilities to the employees or other persons whom the facilities are designed to serve. Such facilities shall be designed and used in such a manner as to at no time constitute a nuisance, a hazard or an unreasonable impediment to traffic.

Two or more uses may provide for required parking in a common parking lot if the total space provided is not less than the sum of the spaces required for each use individually. However, the number of spaces required in a common parking facility may be reduced below this total by special exception if it can be demonstrated to the Zoning Hearing Board that the hours or days of peak parking needed for the uses are so different that a lower total will provide adequately for all uses served by the facility.

For parking areas of three or more vehicles, the area not landscaped and so maintained, including driveways, shall be graded, surfaced with asphalt or other suitable material and drained to the satisfaction of the Borough Engineer to the extent necessary to prevent dust, erosion or excessive water flow across streets or adjoining property. All off-street parking spaces shall be marked so as to indicate their location. Failure to keep parking areas in satisfactory condition, i.e., free from holes, shall be considered a violation of this Chapter.

The minimum number of off-street parking spaces within the zoning district designated as “Pedestrian-Oriented Commercial” (C-1) may be decreased or waived when authorized as a special exception in accordance with §27-1327 if the Zoning Hearing Board finds that such requirements are impracticable or would require destruction of important architectural or landscape elements and the unreasonableness of such regulations is clearly demonstrated.

The design standards specified below shall be required for all off-street parking facilities with a capacity of three or more vehicles built after the effective date of this Chapter.

Parking areas shall be designed to permit each motor vehicle to proceed to and from the parking space provided for it without requiring the moving of any other motor vehicles.

For the purpose of servicing any property held under single and separate ownership, entrance and exit drives crossing the street lot line shall be limited to two along the frontage of any single street, and their center lines shall be spaced at least 80 feet apart on all corner properties, drives shall be spaced a minimum of 60 feet, measured at the curbline, between the center line of any entrance or exit drive and the street line of the street parallel to said access drive.

In no case shall parking areas for three or more vehicles be designed to require or encourage cars to back into a public street in order to leave the lot.

Parking spaces are not permitted in front of the building setback line. All parking spaces and access drives shall be at least five feet from any side or rear lot line, except for the additional requirements in buffer yards.

All artificial lighting used to illuminate any parking space or spaces shall be arranged that no direct rays from such lighting shall fall upon any neighboring property or streets.
