A nonconforming use may be changed to another nonconforming use by the grant of a special exception only upon determination by the Zoning Hearing Board, after public hearing, that the proposed new use will be similar to or less detrimental to its neighborhood and abutting properties than is the use it is to replace. In evaluating relative detriment, the Zoning Hearing Board shall take into consideration, among other things, potential traffic generation, nuisance characteristics (such as emission of noise, dust, odor, glare, and smoke), fire hazards, and hours and manner of operation, availability of sufficient parking facilities, storage and manner of waste removal, area and height of the building, and suitability of the building for conversion to a conforming use. The applicant shall demonstrate that a nonconforming use cannot reasonably be changed to a use permitted by-right. The Zoning Hearing Board may condition the grant of a Special Exception to change a nonconforming use. Where the proposed nonconforming use requires a lesser area of utilization than the existing nonconforming use, the Zoning Hearing Board is authorized to require measures such as, but not necessarily limited to, a reduction in the area of the structure used, and if relevant, designation of enclosed portions of the lot to be utilized for the nonconforming use, and may impose additional conditions or restrictions as authorized by this chapter.
