Sliding scale using four increments for open space provision <br />Percentage range (33% - 50%) is <br />divided into 3 equal increments Lot size is decreased by increments of 13,333.33 sq. ft. and <br />rounded to nearest whale number. 13,333.33 sq. ft. is the <br />of 5.67 difference between 80,000 sq. ft.
