In expansion of the declaration of legislative intent contained in Article I, § 475-2, of this chapter and the statement of community development objectives contained in Article I, § 475-4, of this chapter, it is hereby declared to be the intent of this Article IX with respect to the R-5 Special Residence District to establish reasonable standards of performance and to promote the benefits of the low-density single-family residential development in appropriate areas of the Borough, as well as to provide appropriate locations for certain professional offices where the proliferation of unrestricted commercial development would be undesirable. Further, it is the intent of this Article IX to encourage the formation and maintenance of a quiet, compatible, and uncongested environment for business and professional offices intermingled harmoniously with dwellings; to discourage any encroachment by industrial establishments, large-scale commercial development, or other uses which might adversely affect the residential character of surrounding neighborhoods; to allow for conversion of existing dwellings to certain professional offices in order to encourage the preservation of sound residential structures; to give consideration to vehicular circulation and parking; and to encourage the orderly, well-planned development of offices within the district.
