25 <br />SPREADSHEETS AND CHARTS <br />The following charts demonstrate application of the sliding scale from two perspectives: 1. as <br />applied, to a 12 -lot subdivision; and 2. as applied to the same acreage. Charts 1 -A and 2 -A <br />pertain to zoning districts in which the minimum lot size is 40,000 sq. ft.; Charts 1 -13 and 2 -13 <br />pertain to zoning districts or overlay districts in which the maximum density is 1 dwelling unit <br />per 2 acres. <br />1. Chart 1 -A exhibits how the sliding scale applies to 12 -lot subdivisions, the largest <br />subdivisions that could use the sliding scale, where the minimum lot size is 40,000 sq. ft. <br />(The maximum number of lots permitted in a subdivision using private roads is twelve.) <br />Table used to produce Chart 1 -A <br />A <br />B <br />C <br />C = 12 * B <br />(C/43560) <br />D <br />D = A *E <br />(D/43560) <br />E <br />E = C /(1 -A) <br />(E/43560) <br />C= [(1- A) *D] /B <br />D= C <br />F= <br />G= <br />H= (B *D) <br />% open <br />space <br />Min. <br />Lot size <br />(sq. ft.) <br />Lots <br />(sq. ft.) <br />Lots <br />(acres) <br />Open <br />Space <br />Open <br />Space <br />(acres) <br />Total <br />(sq. ft.) <br />Total <br />(acres) <br />down to <br />sq.ft. /acre) <br />sq.ft. /acre <br />33 <br />80,000 <br />960,000 <br />22.04 <br />472,836 <br />10.85 <br />1,432,836 <br />32.89 <br />40 <br />64,000 <br />768,000 <br />17.63 <br />512,000 <br />11.75 <br />1,280,000 <br />29.38 <br />451 <br />52,0001 <br />624,0001 <br />14.331 <br />510,5451 <br />11.721 <br />1,134,545 <br />26.05 <br />501 <br />40,0001 <br />480,0001 <br />11.021 <br />480,0001 <br />11.02 <br />_960,00022.04 <br />2. Chart 2 -A exhibits how the sliding scale. applies to a 24 -acre tract of land where the <br />minumum lot size is 40,000 sq. ft.. The minimum amount of land required for a 12 -lot <br />subdivision, using the sliding scale; is the acreage required for 1 -acre lots with 50% open <br />space (24 acres). Application of the sliding scale (for a subdivision with 1 -acre lots) to a <br />tract of land larger than 24 acres would create a subdivision having either more than twelve <br />lots or' greater than 50% open space and would not be a true comparison of the given <br />options. <br />Table used to produce Chart 2 -A. <br />A <br />B <br />C <br />D <br />E <br />F <br />G <br />H <br />C= [(1- A) *D] /B <br />D= C <br />F= <br />G= <br />H= (B *D) <br />Rounded <br />E(43,560 <br />(A *E) <br />/43,560 <br />down to <br />sq.ft. /acre) <br />sq.ft. /acre <br />whole no. <br />% <br />Minimum lot <br />Number of Lots <br />No. of Lots <br />Total <br />Total <br />Open <br />Lots <br />Open <br />size <br />acres- <br />Area <br />space <br />(acres) <br />Space <br />(sq. ft.) <br />(sq. ft.) <br />(acres) <br />0.33 <br />80,000 <br />8.03 <br />8 <br />22.00 <br />958,320 <br />7.26 <br />14.74 <br />0.40 <br />64,000 <br />8.98 <br />9 <br />22.00 <br />958,320 <br />8.80 <br />13.20 <br />0.45 <br />52,000 <br />10.14 <br />10 <br />22.00 <br />958,320 <br />9.90 <br />12.10 <br />0.50 <br />40,000 <br />11.98 <br />12 <br />22.00 <br />958,320 <br />11.00 <br />11.00 <br />
