23 <br />Table B2. Sliding scale using four increments for open space provision. <br />Percentage range (33% - 50%) is Lot size is decreased by increments of 29,040 sq. ft. <br />divided into 3 equal increments and rounded to nearest whole number. 29,040 sq. ft. <br />Of 5.67 is the difference between 3 acres (max. lot size) and 1 <br />. acre (min. lot size) divided by 3 (the chosen number of <br />(50-33)/3 increments between 33% and 50%). <br />A B <br />Starting with 33%, <br />X=A+5.67 Starting with X = 130,680 sq. ft. at 33% open space, <br />6=Xminus <br /> (130,680 sq.ft.- 43,560 sq.ft.) /3 <br /> <br />open Min. <br />space Lot size <br /> <br /> 33.00 130,680 <br /> 38.67 101,640 <br /> 44.33 72,600 <br /> 50.00 43;560 <br />A fifth increment is added to permit 40,000 sq. ft. lots with the provision of 54% ar greater open <br />space. (Forty-thousand sq. ft. is the smallest lot allowed by the zoning ordinance for areas <br />without water and sewer service. Public roads are required for subdivisions within transition <br />areas, areas in the county where water and sewer service is available or may be extended.) <br />A subdivision with 50% open space can be accommodated on the least amount of land <br />required fora 12-lot subdivision using the sliding scale because the overall density of the <br />zoning district must be maintained. If smaller lots than allowed by the overall density <br />requirement (1 DU/2acres) are permitted (i.e. 40,000 sq. ft. lots), more than 50% of the <br />acreage must be preserved in open space in order to maintain zoning density requirements. <br />Therefore, a 40,000 sq. ft. lot would still require 2acres of land per buildable lot with 54% of <br />the total acreage preserved in open space. 40,000 sq. ft. = 46% of the required 87,120 sq. ft. <br />(40,000/87,120 =.4591 or 45.91 %); required open space = 54% or (100%~6%). However, <br />40,000 sq. ft. lots may be allowed with any open space requirement greater than 54%. <br />The following Tables B3. and B4. show the progression from calculations of equal increments <br />to the recommended open space requirement intervals used for the sliding scale. <br />Table B3.
