Example. An existing lot of record is zoned "R-1E" Single-Family Residential. According to the "design standards" of that district, it should have a minimum area of seven thousand (7,000) square feet and a minimum width of sixty (60) feet. The existing lot of record is eligible for use as long as its area exceeds five thousand two hundred fifty (5,250) square feet (7,000 square feet X 0.75 = 5,250 feet), and its width is greater than forty-five (45) feet (60 feet X 0.75 = 45 feet). In addition, all required yards must be at least seventy-five percent (75%) of those required under the design standards of the "R-1E" District.
