(2) Standard subdivision. A yield plan shall be prepared
for a standard subdivision in accordance with the requirements of
this section and shall include a requirement to provide affordable
housing.
(a)
Density. The permitted number of dwelling units
shall not exceed the number of units that, in the Planning Board's
judgment, would be permitted if the land were subdivided into lots
conforming to the minimum lot size and density requirements of this
chapter applicable to the zoning district (or districts) in which
such land is situated and conforming to all other requirements of
the Town Code.
(b)
Total lot yield shall be determined on buildable
lands only. Subdivision design shall exclude the following features,
unless the applicant shall have obtained a permit from all relevant
regulating authorities approving the applicant's right to place residential
structures in the subject areas:
[2]
Tidal wetlands or freshwater wetlands, as defined
in state and local regulations.
[3]
Bluffs, primary dunes and secondary dunes.
[4]
Beaches below mean high water, as defined by
the United States Coast and Geodetic Survey or latest Tidal Wetlands
Survey, and any beach or area lying between this line and the coastal
erosion hazard line.
[5]
Areas required for park dedication pursuant
to this chapter.
[6]
Areas required for recharge basins or for natural
area recharge.
[7]
Areas required for public or private rights-of-way.
[8]
Areas required for utilities or public facilities,
except that minor utility easements of direct service to the subdivision
may be included.
[9]
Areas for which the development rights have
been transferred, sold or extinguished.
[10]
Areas which the Planning Board shall determine
to be of such character that they cannot be used safely for building
purposes without danger to health or peril from fire, flood, drainage
or other menace to neighboring properties or the public health, safety
and welfare.
(c)
Affordable housing requirement. Every new standard
residential subdivision involving the creation of five or more lots
shall comply with the requirements herein to provide affordable housing.
[Amended 8-12-2008 by L.L. No. 9-2008; 3-26-2024 by L.L. No. 7-2024]
[1]
Twenty percent of the lot yield as determined pursuant to §
240-10B(2)(a) and
(b) shall be set aside as moderate-income family dwelling units (MIFDUs), as defined, created and administered under the provisions of the Affordable Housing District, §§
280-24 through
280-33 of this Code. Each MIFDU shall be created subject to covenants and restrictions as set forth at §
280-30 or through another mechanism approved by the Town Board that will keep units perpetually affordable. The number of MIFDU units required in a subdivision shall be rounded up to the next whole number if the fractional requirement is 0.50 or greater, and shall be rounded down to the next whole number if the fractional requirement is less than 0.50.
[2]
Fee waiver. An applicant shall receive a waiver of all application fees, building permit fees, plan review fees, inspection fees, park and playground fees and such other development fees and costs attributable to the MIFDUs built in the subdivision. A waiver may not be granted for sanitary flow credits purchased pursuant to the provisions of Chapter
117.
[3]
Phasing of construction. The applicant shall provide to the
Planning Board a phasing plan that provides for the timely and integrated
development of the affordable housing units as the subdivision is
built out. The phasing plan shall provide for the development of the
MIFDUs concurrently with the market rate units. Building permits shall
be issued for dwelling units within the subdivision based on the phasing
plan. The phasing plan may be adjusted by the Planning Board when
necessary in order to account for different financing and funding
environments, economies of scale, and infrastructure needs applicable
to the development of the market rate and the MIFDUs. The phasing
plan shall also provide that the MIFDUs shall not be the last units
to be developed in the applicable subdivision.
[4]
Exterior appearance. The exterior appearance of the MIFDUs shall
be visually compatible with the market rate units in the development.
External building materials and finishes shall be substantially the
same in type and quality for MIFDUs and market rate units.
[5]
Appeal. A developer of any project subject to the requirements
of this chapter may appeal to the Town Board for a reduction, adjustment
or waiver of the requirements based upon the absence of any reasonable
relationship or nexus between the impact of the development and the
inclusionary requirement.
(d)
Yield must be further determined in consideration
of the ERSAP.
(3) Conservation subdivision. For all conservation subdivisions,
one of the following formulas shall be used to calculate yield.
(a)
75/75 conservation subdivision.
|
Buildable Lands ÷ Minimum Lot Area of
Zoning District = Yield on Entire Parcel
|
---|
|
Yield on Entire Parcel x 25% = Yield on Developable
Area
|
---|
|
Total Buildable Lands x Percentage of Buildable
Lands not permanently preserved (up to 25%) = Developable Area
|
(b)
80/60 conservation subdivision.
|
Buildable Lands ÷ Minimum Lot Area of
Zoning District = Yield on Entire Parcel
|
---|
|
Yield on Entire Parcel x 40% = Yield on Developable
Area
|
---|
|
Total Buildable Lands x Percentage of Buildable
Lands not permanently preserved (up to 20%) = Developable Area
|
C. Primary and secondary conservation area plan. All
subdivisions shall be created in accordance with the primary and secondary
conservation area design process described in this section. All sketch
plans shall include the documentation set forth below.
(1) Primary and secondary conservation areas as defined in §
240-3 shall be identified using existing resources and site analysis plan(s) (ERSAP) as a base map.
(2) Location of house sites. Using the information from Subsection
C(1) above, the yield as determined pursuant to this chapter, the base map and the ERSAP, potential house sites shall be located. House sites should generally be located not closer than 100 feet to primary conservation areas and 50 feet to secondary conservation areas, taking into consideration the potential negative impacts of residential development on such areas as well as the potential positive benefits of such locations to provide attractive views and visual settings for residences.
(3) Alignment of streets and trails.
(a)
A street plan shall be designed to provide access
to each house, complying with the standards identified herein and
bearing a logical relationship to topographic conditions. Impacts
on proposed open space shall be minimized, particularly with respect
to crossing environmentally sensitive areas such as wetlands and traversing
slopes equal to or exceeding 15%. Existing and future street connections
may be required in order to eliminate the number of new culs-de-sac
to be maintained by the Town and to facilitate access to and from
homes in different parts of the tract and adjoining parcels.
(b)
The potential location of recreational and off-road
walking trails shall also be noted.
(4) Location of lots. Bubble lines shall denote the proposed
locations.
D. Cluster design. The design of a cluster subdivision plat shall be pursuant to the requirements of Article
XI, Cluster Development, herein, if applicable.
E. Site context map. A map showing the location of the
proposed subdivision within its neighborhood context shall be submitted.
For all sites, such maps shall be at a scale of one inch equals 100
feet, and shall show the relationship of the subject property to natural
and man-made features existing within 500 feet of the site. The features
that shall be shown on site context maps include topography (from
USGS maps), state and/or federal wetlands, woodlands over one-half
acre in area (from aerial photographs), public roads and trails, utility
easements and rights-of-way, public land, and protected lands.

septic systems, water mains and lines, wells, culverts and drains
on the property, with pipe sizes, grades and direction of flow.
(2) Width and location of any streets or public ways or
places shown on the Official Map or Master Plan, and any updates to
it, if such exist, within the proposed subdivision, and the width,
location, grades and street profiles of all proposed streets or public
ways.
(3) Location and size of any existing fire control structures,
fire hydrants and wells.
L. Calculations. The area of the parcel to be set aside
for cluster and/or preservation purposes and the area to be developed
shall be calculated and set forth in a table format.
The Planning Board shall study the practicability
of the sketch plat, considering the requirements of this chapter,
including identified primary and secondary conservation areas. Particular
attention shall be given to the arrangement, location, and width of
streets, their relation to the topography of the land, water supply,
sewage disposal, stormwater drainage, erosion and sediment control,
lot sizes and arrangement, the future development of adjoining lands
not yet subdivided, current zoning regulations, and the comprehensive
plan.
