Clustered subdivisions are not permitted in the RR1 or RR2 zoning
districts. Clustered subdivisions are residential developments in
which groups or clusters of dwelling units may be located on adjoining
individual building lots which may be smaller than the required minimum
lot size for the zoning district in which they are located but within
which land is set aside as common open space, so long as the maximum
number of lots permitted shall not exceed that allowed per the underlying
zoning district. The following standards apply to development in clustered
subdivisions in place of the otherwise applicable dimensional requirements
for the zoning district in which the development is located:
A. Lot density calculation.
(1) Net residential acreage. The net residential acreage shall be calculated
as defined.
(2) Maximum number of lots allowed. The maximum number of lots allowed
in a clustered subdivision shall be calculated by dividing the net
residential acreage by the minimum lot size allowed in the applicable
zoning district (net residential acreage/minimum lot size allowed
in zoning district = maximum number of lots allowed).
B. Minimum lot size. If the lots are connected to the public water and
sewer systems, the minimum lot size for each single-family dwelling
shall be 30,000 square feet and for each duplex dwelling shall be
40,000 square feet. If the lots are connected to the public water
system but not the public sewer system, the minimum lot size for each
single-family dwelling shall be 45,000 square feet and 60,000 square
feet for each duplex. If the lots are not connected to the public
water and sewer system, the minimum lot size for each single-family
dwelling shall be 60,000 square feet and for each duplex dwelling
shall be 80,000 square feet.
C. Lot setbacks.
(1) Setback requirements for a clustered subdivision shall be the same
as those required in the zoning district in which the subdivision
is located.
(2) Sheds and driveways are permitted a minimum setback of 15 feet from
the side and rear lot lines.
D. Frontage. Each lot shall have no less than 75 feet of lot frontage
on a street.
E. Buffer. A buffer of at least 75 feet in width shall be created around
the entire perimeter of the subdivision. For subdivisions that front
on Tuttle, Greely, Blanchard, and Foreside Road, the buffer along
those roads shall be 150 feet. Where possible, existing trees and
vegetation shall be preserved in buffers, except that vegetation classified
as invasive may be removed.
