<br />3. Chart 1-B exhibits how the sliding scale applies to 12-lot subdivisions where the maximum
<br />allowable density is one dwelling unit per two acres. (The maximum number of lots
<br />permitted in a subdivision using private roads is twelve.)

<br />4. Chart 2~B exhibits how the sliding scale applies to a 24-acre tract of land. The minimum
<br />amount of land required fora 12-lot subdivision, using the sliding scale, is the acreage
<br />required for 1-acre lots with 50% open space (24 acres). Application of the sliding scale
<br />(for a subdivision with 1-acre lots) to a tract of land larger than 24 acres would create a
<br />subdivision having either more than twelve lots or greater than 50% open space and would
<br />not be a true comparison of the given options.
