The maximum density on net buildable site area is determined
on the basis of the percentage of base site area with resource protection
land and open space. The maximum number of dwelling units permitted
on a particular tract shall not exceed the number of dwelling units
that could be constructed on the site given the development constraints
of the physical site and the otherwise applicable Township ordinance
requirements. A standard subdivision plan showing sufficient detail
to demonstrate the maximum number of dwelling units that could be
constructed on the site shall be provided to the Township and approved
by the Township engineer.

NOTES:
1 The percentage of base site area classified as resource protection land is determined through the site capacity calculations, § 200-52. A minimum of 40% of the base site area of sites planned for single-family attached residences and for two-family residences must be devoted to resource protected lands and open space. If resource protected lands encumber less than 40% of the base site area, then additional land shall be devoted to open space so as to equal 40%.
2 The maximum density
on net buildable site area is determined on the basis of the percentage
of base site area with resource protection land and open space.

NOTES:
1 Single-family
attached units shall not have less than 24 feet of width at the building
line, except that at the option of the developer 25% of the total
building lots of attached dwelling units may be reduced to widths
of 20 feet at the building line.
2 Where a yard abuts a major collector or arterial road listed in § 200-63 of this chapter, the building setback shall be increased to 80 feet for collector roads and 100 feet for arterial roads. For any building fronting onto any other public right-of-way the minimum setbacks shall be 30 feet, whereas for any building fronting onto a public area or private right-of-way the minimum yard shall be 15 feet.
3 The minimum
side yard between connected dwelling unit groups shall be 25 feet.

2 Notwithstanding
the maximum density on net buildable site area, the maximum number
of dwelling units permitted on a particular tract shall in no circumstance
be greater than the maximum number of dwelling units that actually
could be constructed on the site without open space clustering given
the development constraints of the physical site and the otherwise
applicable Township ordinance requirements. A plan showing sufficient
detail to demonstrate the maximum number of dwelling units that could
be constructed on the site shall be provided to the Township.

3 The minimum net lot size and minimum average lot size is permitted only where the resource protection land, including open space as defined in § 200-7, exceeds 51% of the base site.
