The amount of off-street parking to be provided is reasonable in relation to the nature of the use to be served and that the number of parking spaces, as required by this Section, is not compatible with the actual off-street parking requirements of the particular use because of unusual circumstances regarding any such use.

Any off-street parking proposed to be provided other than on the lot of the use to be served is reasonably located and readily accessible in relation to the use to be served and is reasonably related to surrounding uses of land and that said parking area is either within the same block or not more than five hundred (500) feet distant from the boundaries of the lot to be served and that said parking is permitted in the district in which it is located.

Modification of any setback or yard requirement for the parking area or modification of any construction requirement is necessary because of unique or unusual circumstances which render the specific requirements of this Section unreasonable and without benefit to surrounding property.
