When a use is not specifically listed in this chapter as permitted or as a conditional use, the use may be allowed as a special exception if it is determined by the Zoning Hearing Board, after review and recommendation by the Township Planning Commission, that the use is similar to other uses listed in the applicable zoning district and that the proposed use meets the criteria outlined in this article. It is further recognized that every conceivable use cannot be identified in this chapter and, anticipating that new uses will evolve over time, this article provides for the process in which a proposed use can be compared and measured against those listed in the applicable zoning district for determining similarity.
