The maximum number of density units (i.e., units per acre or
DU) shall not exceed the maximum allowable DU for a subdivision in
the district in which the property is located. Any regulations contained
in this chapter and in the Town zoning law restricting the number of dwelling units permitted in
a subdivision shall apply. The calculation of buildable yield for
a major subdivision shall be based on the following formula. The buildable
yield (BY) shall be used to determine the allowable density units
per the area, yard and bulk chart of the Town zoning law.
A. The BY calculation shall be determined by subtracting the constrained
land areas of the property (i.e., NYSDEC and USACOE regulated wetlands,
and lands within the 100-year floodplain area, steep slope areas of
greater than 15% and public improvements) for which the applicant
has not secured and has not submitted to the Planning Board permits
or approvals that would allow development in such constrained land
areas, as follows:
Where:
|
T
|
=
|
Total acreage inside the boundary lines of the project parcel.
|
W
|
=
|
Total acreage inside the boundary lines of the project parcel
and within a NYSDEC or USACOE regulated wetland (exclusive of any
buffer area).
|
F
|
=
|
Total acreage inside the boundary lines of the project parcel
and within the 100-year floodplain area where the base elevations
and flood hazard are determined exclusive of any flood area within
a regulated state or federal wetland.
|
S
|
=
|
Total acreage inside the boundary lines of the project parcel
and containing slopes of 15% or greater.
|
I
|
=
|
The total acreage of required public improvements (i.e., roads,
sidewalks, stormwater management facilities, utility easements).
|
BY
|
=
|
Maximum number of acres that can be developed and that form
the basis for determining the maximum number of residential dwellings
that may be created per the area, yard and bulk chart.
|
B. The BY calculation set forth in Subsection
A above shall be adjusted to include, in whole or in part, the constrained land area(s) for which the applicant has secured the necessary permits or approvals from applicable local, state or federal agencies authorizing development in such area(s) and has submitted copies of said permits or approvals to the Planning Board. If the parcel is not proposed for connections to central sewage disposal facilities, the plan shall also include an assessment and certification by a professional engineer as to the suitability of the soils to accommodate individual sewage disposal systems. The Planning Board, in its sole discretion, shall determine whether the plan is realistic and reflects a development pattern that could reasonably be implemented.
