No other regulation withstanding, no new lot may be created, or subdivision approval granted, in the Borough of Riverton within any residential district unless the lot or lots created is or are equal in size, shape and orientation, at a minimum, to the prevailing lot size, shape and orientation of lots along the streetscape of the street upon which the lot or lots are to be created. The prevailing lot size, shape and orientation shall be the average size, shape and orientation of all lots fronting along both sides of a street to a point of intersection with another street or, if no intersecting street exists, a distance of 600 feet from any side property line of a proposed lot. The term "orientation" means the relationship which existing buildings and structures on existing lots bear to front, side and rear lot lines, as well as building and structures located on adjacent lots. This standard is designed to advance the design, layout and aesthetic values associated with existing patterns of development in the community. It shall be interpreted and enforced to advance these values.
