§ 27-601.   General Regulations Applying to Required Off-Street Parking Facilities.
   1.   Existing Parking. Structures and uses in existence at the date of adoption of this Chapter shall not be subject to the requirements of this Part so long as the kind or extent of use is not changed, provided that any parking facilities now serving such structures or uses shall not in the future be reduced below such require ments.
   2.   Change in Requirements. Whenever there is an alteration of structure of a change or extension of a use which increase the parking requirements according to the standards of § 27-600, the total additional parking required for the alteration, change or extension shall be provided in accordance with the requirements of that Section.
   3.   Conflict with Other Uses. No parking area shall be used for any use that interferes with its availability for the parking need it is required to serve.
   4.   Continuing Character of Obligation. All required parking 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 when such reduction is in conformity with the requirements of this Part. Reasonable precautions shall be taken by the owner or sponsor of particular uses to assure the availability of required facilities to the employees of 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, or a hazard, or unreasonable impediment to traffic.
   5.   Joint Use. 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 under Part 14 if it can be demonstrated to the Zoning Hearing Board that the hours or days of peak parking need for the uses are so different that a lower total will provide adequately for all uses served by the facility.
   6.   Fractional Spaces. Where the computation of required parking space results in a fractional number, only the fraction of one-half more shall be counted as one
   7.   Location of Parking Space. Required off-street parking areas shall be on the same lot or premises with the principal use served, or, where this requirement cannot be met, within 300 feet of the principal use served within the same district.
   8.   Maintenance of Parking Areas. For parking areas of 3 or more vehicles, the area not landscaped and so maintained, including driveways, shall be graded, surfaced with asphalt or other suitable hard surface material and drained to the satisfaction of the Township Engineer to the extent to prevent dust, erosion, or excessive water flow across streets or adjoining property. All off-street parking spaces shall be marked as to indicate their location.
   9.   Parking of Commercial Vehicles. Commercial motor vehicles as defined in Part 2 are not permitted to park in the LU, MR or PR District other than for normal commercial deliveries and services to the residents.
