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.

If the lot is served by on-lot private water or on-lot sewage
facilities, the minimum lot area permitted shall be 34,000 square
feet with a minimum lot width at the building line of 110 feet.

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.
4 No two
detached buildings shall be closer to one another than the combined
height of the two buildings, measured at the highest point on each
building.
