Special exceptions are unique and their effect on the surrounding environment cannot be determined in advance of the use being proposed for a particular location. At the time of application, a review of the location, design, configuration, and potential impact of the proposed use shall be conducted by the Township by comparing the use to established development standards and design guidelines. This review shall determine whether the proposed use addresses the general and specific standards and criteria identified in this Part, and chapter, and whether it should be permitted, by weighing the public need for, and the benefit to be derived from, the use, against the impact which it may cause.
