Purpose. In recognition of innovations and changes in the technology of residential land development which can be beneficial to the future well-being of the Borough, but which benefits are unlikely to be realized through the uniform treatment of area, yard and building requirements on a lot-by-lot basis, and also in recognition of certain uses which are necessary to serve the needs and convenience of the Borough, but which uses may be or become inimical to the public health, safety and general welfare by reason of their inherent nature and/or operation and, therefore, require special and proper consideration of existing and probable future conditions and characteristics of the surrounding area, this chapter provides that such uses are declared to be conditional uses.
