71 <br /> As shown on the following "Building Constraints Map', wetlands,floodplains and alluvial soils, <br /> and steep slopes are limiting factors for development. When combined with soils that do not perk <br /> well,the conservation approach produces lots which not only recognize the natural limitations of <br /> the land but contribute to the preservation of Primary and Secondary Conservation Areas. <br /> The following table provides a comparison of Rural Character and Flexible Development <br /> strategies. As noted in the table, it may be possible, on land that perks extremely well and has no <br /> Primary Conservation Areas, to achieve a density of 108 lots per 100 acres. <br /> Under the current regulations and ideal conditions,the maximum density is 100 lots per 100 acres. <br /> The difference between the two is accounted for by the incentive of counting street right-of--way <br /> as part of the 40,000 sq.ft. lot size. What one will generally see, however, is the typical situation <br /> where poor soils, separately or in combination with other building constraints, limit the density <br /> to 72 lots per 100 acres. <br /> Can;parison of Rurvt Character and Fkxibk Development Optaions . <br /> Development Conventional Two-Acre Lot <br /> Standards Development Option Conservation Lot Option' <br /> Maximum - 36,800 sq.ft. <br /> (0.84 acres) <br /> Lot Size Required 80,000 sq.ft.

If lot area calculations include half the street right-of-way,the minimum permitted lot size <br /> is 81,900 sq.ft. (1.88 acres). <br /> Flexible Development 13 <br />
