[Added 5-18-2006 by L.L. No. 2-2006]
Purposes. A subdivision is considered a conservation
subdivision when lots and dwelling units are located closer together
than otherwise allowed in a conventional subdivision and where open
space is created on the remainder of the property without increasing
density for the tract as a whole. Conservation subdivisions are authorized
under § 278 of the New York State Town Law, are also referred
to as "cluster subdivisions" or "open space subdivisions," and are
encouraged herein. In conformance with the Town's Comprehensive Plan,
the purposes of a conservation subdivision are as follows:
A.
To provide greater economy, efficiency and convenience
in the siting of services and infrastructure, including the opportunity
to reduce road lengths, utility runs, and the amount of paving required;
B.
To conserve important open lands, including those
areas containing unique and sensitive natural features, such as steep
slopes, floodplains, stream corridors, and wetlands by permanently
setting them aside from development;
C.
To protect areas of the Town with productive agricultural
soils for continued or future agricultural use;
D.
To provide multiple options for landowners to minimize
impacts on environmental resources and natural or cultural features
such as mature woodlands, tree lines, critical wildlife habitats,
historic buildings and sites, and stone walls;
E.
To create developments with direct visual access to
open land;
F.
To provide a reasonable setback for new development
adjacent to lands in active farming due to potential incompatibility
with nonfarm uses;
G.
To implement policies to conserve a variety of irreplaceable
and environmentally sensitive resource lands, encourage the future
existence of abundant open spaces and maintain a rural aesthetic quality
in connection with the development of lands within the Town;
H.
To conserve scenic views and elements of the Town's
rural character, and to minimize perceived density, by limiting views
of new development from existing roads;
I.
To promote development in harmony with the goals and
objectives of the Town's Comprehensive Plan; and
J.
To mitigate identified environmental impacts under
the State Environmental Quality Review Act (SEQRA).
Authorization is hereby granted to the Town of Ghent Planning Board ("Planning Board") to modify applicable provisions of the Town of Ghent Zoning Law (Ghent Code Chapter 190), with respect to lot size, lot width, depth, yard, and other applicable requirements as well as type of residential use, subject to the purposes, standards, and provisions set forth herein, in order to accommodate and encourage conservation subdivisions in a situation where such subdivisions would be appropriate in accordance with the provisions herein. The Planning Board shall have the authority to request a preapplication conference seeking application information for a proposed conservation subdivision if same is authorized pursuant to these provisions. The applicant shall make a deposit, in accordance with the Town's Fee Schedule, sufficient to cover the preapplication expenses required for review by the Town's professional Engineer, Planner and Attorney. Neither the applicant nor the Planning Board shall be bound by the exchange of ideas during the preapplication conference.
[Amended 5-17-2012 by L.L. No. 4-2012]
The provisions with respect to conservation
subdivisions shall only apply in an RRA-1 Zone or an RRA-2 Zone in
the following cases:
A.
Notwithstanding anything set forth herein to the contrary,
a conservation subdivision shall not be required where each of the
lots of the subdivision exceed 10 acres. In such event, it shall be
noted on the approved subdivision map that no parcel may be further
subdivided so as to create a lot which is less than 10 acres, and
the applicant shall also note this restriction on the deed of conveyance.
B.
Also, if the Planning Board determines that the goals
and objectives for a conservation subdivision are not present in accordance
with the provisions herein, then the Planning Board may determine
in its discretion that a conservation subdivision is not required.
For purposes of determining the number of new
lots that may be created with respect to any one parcel, the Planning
Board shall determine this figure by determining the cumulative number
of new lots created or proposed to be created from a parcel existing
as of January 1, 1990, regardless of change of ownership. It shall
be the responsibility of the applicant to provide the Planning Board
with all necessary information requested in determining this figure,
including, if requested, copies of all pertinent deeds, survey maps,
and other documentation to establish the correct figure.
The Planning Board may consider the issue of
segmentation if the applicant is the owner of or has a legal interest
in property adjacent to the parcel for which subdivision approval
is sought, and may treat the entire property in which the applicant
has an interest as one parcel. The election to treat all such parcels
as one shall be at the sole discretion of the Planning Board.
The Planning Board may require a conservation
subdivision where it finds any one or more of the following elements
present, as determined through review of an existing resources map
and site analysis as described herein, justifying conservation of
natural, cultural or historic resources, scenic features, or preservation
of neighborhood character.
A.
Slopes: slopes of 15% or greater which are 2,000 square
feet or more and which are a contiguous sloped area.
B.
Water resources: wetlands, aquifer and aquifer recharge
areas, municipal water supply watershed areas, one-hundred-year floodplain
areas, New York State classified streams, or a Town-designated water
protection area.
C.
Agricultural lands: active farmland within or without
a New York State-certified agricultural district and prime farm soils.
D.
Community water and/or sewer: sites where community
sewer, or community water are available or planned.
E.
Critical environmental areas: lands contiguous to
or within a critical environmental area designated pursuant to Article
8 of the Environmental Conservation Law.
F.
Designated open space areas: lands contiguous to publicly
owned or designated open space areas, privately owned lands or lands
owned by a not-for-profit entity having designated conservation areas,
or areas identified as open space in any approved conservation subdivision.
G.
Historic structures and sites: historic structures
or areas of national, state or local importance.
H.
Views of open fields of five acres or more or views
of special features such as but not limited to ponds, lakes, streams,
plateaus, or mountains which can be seen from a state, county or Town
roadway.
I.
Significant natural areas and features: areas with
special vegetation, significant habitats, or habitats of endangered
or threatened species.
J.
Recreation: lakes, ponds or other significant recreational
areas, or recreation sites designated in the Town's Comprehensive
Plan.
Permitted, accessory and special permit uses
within a conservation subdivision shall be the same as those otherwise
allowed in the zoning district in which the development is located.
As an alternate to single-family dwellings or two-family dwellings,
townhouse or condominium-style development is also permitted within
a conservation subdivision, provided proper safeguards are created
in connection with the preservation and maintenance of lands in common
ownership.
The permitted number of dwelling lots shall not exceed the number of units that would be permitted if the land were subdivided into lots fully conforming to the minimum lot size and density requirements of the Zoning Law (Ghent Code Chapter 190). Exceptions to density requirements can be made by the Planning Board in connection with incentives for open space preservation as provided for herein. To determine density, the applicant shall submit a yield plan, in accordance with the provisions of the Ghent Code. In this regard, there shall be subtracted from the total gross acreage of the proposed development parcel, any acreage which is not subject to development, including but not limited to wetlands, watercourses, one-hundred-year floodplains, slopes of 15% or greater, which are 2,000 square feet or more and which are a contiguous sloped area and infrastructure such as roadways, water systems and septic systems. To determine the base number of allowable residential units on the site, divide the remaining acreage subject to development by the minimum allowable number of acres per unit required in the zoning district and round down for fractional units of 0.5 or less and round up fractional units greater than 0.5. The resulting number is the base density allowed on the lot proposed to be subdivided.
In a conservation subdivision, there shall be
no minimum lot size required. Further, in a conservation subdivision,
there shall be no minimum lot width and no minimum front, rear, or
side yard requirements.
A.
Once the maximum permissible number of lots in a conservation
subdivision has been established, the next step is to submit a sketch
plan. The purpose of a sketch plan is to facilitate review of the
proposed subdivision in conformance with the provisions for conservation
subdivision and the Town's Comprehensive Plan. Sketch plan submission
is a way to help applicants and Planning Board members develop a better
understanding of the property and to help establish an overall design
approach that respects its special or noteworthy features, while providing
for the density permitted under these regulations.
B.
There shall be a two-part sketch plan review process.
Part 1 shall consist of the submittal of an existing resources and
site analysis that will provide the Planning Board with information
to allow it to determine whether a conservation subdivision will be
required. If a conservation subdivision is required, Part 2 of this
section applies and shall consist of a conservation subdivision map
to be prepared by the applicant in accordance with the four-step design
process set forth therein. This process shall include an identification
of primary and secondary conservation lands and planned development
areas within a parcel.
(1)
Part 1: An existing resources and site analysis shall be prepared to provide the Planning Board with a comprehensive analysis of existing conditions, both on the proposed development site and within 500 feet of the site. Conditions beyond the parcel boundaries may be described on the basis of existing published data available from governmental agencies, and from aerial photographs. The existing resources and site analysis shall consist of a site context map and a natural, cultural and historic features map as follows: a) Site context map. A map showing the location of the proposed subdivision within its neighborhood context shall be submitted. For all sites, such map shall be at a scale not less than one inch equals 500 feet and shall show the relationship of the subject property to natural and man-made features existing within 1,000 feet of the site. The features that shall be shown on the site context map include existing structures, public roads, utilities, utility easements and rights-of-way and public land. b) Natural, cultural and historic features map. The applicant shall identify those natural, cultural and historic features listed in § 156-33 of these regulations on a Map at a scale of one inch equals 100 feet. As an alternative to the creation of this map, the applicant can elect to move on to Part 2 of this section, and include the information required herein on the conservation subdivision map to be created pursuant to Part 2 of this section. The existing resources and site analysis becomes the basis for the Planning Board's determination whether a conservation subdivision will be required. Where a conservation subdivision is determined to be required, this analysis becomes the basis for the four-step design process, as referenced herein.
(2)
Part 2: Conservation subdivision map. There shall
be a four-step design process for conservation subdivisions. A conservation
subdivision map shall be prepared and presented to the Planning Board
and shall include the information required in this four-step process.
The steps are as follows:
(a)
Step 1: Identify primary conservation areas.
This shall include wetlands, lakes, ponds, steep slope areas of 15%
or greater, which are 2,000 square feet or more and which are a contiguous
sloped area, one-hundred-year floodplains, streams, and other developmentally-constrained
areas as may be identified by the Planning Board.
(b)
Step 2: Identify secondary conservation areas.
Secondary conservation areas shall include scenic roads and viewsheds;
trails; historic sites and structures, including foundations and stone
walls; hedgerows, significant or threatened or endangered habitats,
large isolated trees; critical environmental areas, active agricultural
lands, prime farm soils, aquifers and such other important natural
areas as shall be identified by the Planning Board.
(c)
Step 3: Identify potential development areas.
This should include potential house sites which shall be tentatively
located using the proposed open space lands as a base map as well
as other relevant data on the existing resources and site analysis
plan, such as topography and soils. House sites should generally be
located not closer than 100 feet from primary conservation areas and
50 feet from 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 use and visual settings for residences. Potential
development areas shall also include preliminary location of a preliminary
street plan showing vehicular access to each proposed residence and
complying with the standards identified herein and bearing a logical
relationship to topographic conditions. Impacts of the street plan
on proposed open space land shall be minimized, particularly with
respect to crossing environmentally sensitive areas such as wetlands
and slopes of 15% or more. The existing and future street connections
are encouraged 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. Culs-de-sac are appropriate
when they support greater open space conservation or provide enhanced
pedestrian linkage.
(d)
Step 4: Locate potential house sites. This shall
include drawing in the lot lines to delineate the boundaries of individual
residential lots.
A preliminary conservation subdivision plan shall include all of the requirements set forth in Chapter 156 of the Ghent Code except where such requirements are modified by the provisions set forth in this conservation subdivision regulation. The provisions of this regulation are designated to supplement and, where appropriate, replace Chapter 156 of the Ghent Code, which shall otherwise continue to apply:
A.
The Planning Board shall review the plan to assess its accuracy and thoroughness. Unless otherwise specified by the Planning Board, such plans shall be prepared at the scale of one inch equals 100 feet. All inventory information identified as part of the sketch plan process in § 156-37 shall also be identified on the preliminary plat map, but at the scale specified above. In addition, the following information shall be included in this plan:
(1)
Topography, including contour lines, which shall be
at two-foot intervals. However, the Planning Board may specify greater
or lesser intervals on exceptionally steep or flat sites. Topography
for major subdivisions shall be prepared by a professional land surveyor
or professional engineer from an actual field survey of the site or
from stereoscopic aerial photography and shall be coordinated with
official USGS benchmarks.
(2)
The location of natural drainage swales and required
one-hundred-foot buffer zones for wetlands.
(3)
Vegetation cover conditions on the property according
to general cover type, including cultivated land, permanent grass
land, fields, hedgerows, woodlands and wetlands, isolated trees with
a caliper in excess of 12 inches, and the actual canopy line of existing
trees and woodlands. Vegetation types shall be described by plant
community, relative age and condition.
(4)
Soil series, types and phases, as mapped by the U.S.
Department of Agriculture, Natural Resources Conservation Service
and Columbia County Soil Survey, and accompanying data published for
each soil relating to its suitability for construction and septic
suitability.
(5)
A viewshed analysis showing the location and extent
of views into the property from public roads.
(6)
Geologic formations on the proposed development parcel,
based on available published information or more detailed data obtained
by the applicant.
(7)
All easements, restrictions or other encumbrances
of property which are proposed for the parcel, as well as all current
easements, restrictions and current encumbrances relating to the parcel,
which have been filed of record with the Columbia County Clerk's Office,
shall be shown on the plan.
B.
The Planning Board shall schedule site visit(s) in
connection with review of the preliminary plan.
A.
In all zoning districts, a conservation subdivision
must preserve at least 50% of the tract's acreage as open space land.
Parking areas, roads, house sites and their improvements shall not
be included in the calculation to determine the amount of available
open space. However, the entire tract, apart from these exceptions,
shall be considered in determining the required amount of open space.
The following facilities or improvements may be located on open space
land: common septic systems, water systems, stormwater systems, bike
paths, walking trails, and other common community facilities that
do not involve buildings, such as tennis courts, swimming pools, and
playgrounds. Farm buildings on an active farm may also be located
in the open space area used to meet the open space requirements.
B.
The proposed subdivision design shall strictly minimize
disturbance of environmentally sensitive areas. Primary and secondary
conservation areas shall be included in the required open space areas
to the greatest extent practical. The Planning Board shall encourage
areas of open space to be connected, where appropriate. Where important
open space areas exist contiguous to the subject parcel, every effort
shall be made to locate the on-site protected open space adjacent
to these open space areas.
C.
The Planning Board shall encourage areas of open space
along the state, county, and Town roadways located in the Town, where
appropriate, to conserve scenic views and elements of the Town's rural
character.
D.
The final determination of which land has the most
conservation value and should be permanently protected from development
shall be made by the Planning Board, based upon the criteria set forth
in this regulation.
E.
A recreational fee in lieu of land, as set forth in
the Town's Fee Schedule, may be imposed to accommodate the foreseeable
recreational needs of the residents of the proposed subdivision, should
the Planning Board determine that the open space lands set aside as
part of the conservation subdivision will not provide adequately for
these recreational needs.
Development areas for the location of house
lots include the necessary building envelope for each dwelling unit,
constituting the remaining lands of the tract outside of the designated
open space areas. House lots shall be designed in accordance with
the following standards:
A.
House lots shall not encroach upon primary conservation
areas and also, unless not practical, upon secondary conservation
areas. To the extent possible, house lots shall be grouped together
to maximize protection of contiguous areas of open space.
B.
All new dwellings shall meet the following setback
requirements to the greatest extent practicable:
(1)
From all external road ultimate rights-of-way: 100
feet.
(2)
From all other tract boundaries: 50 feet.
(3)
From agricultural lands either bordering or within
the tract: 200 feet.
(4)
From buildings or barnyards housing livestock: 300
feet.
(5)
From active recreation areas, such as tennis courts
or playing fields: 150 feet.
C.
Views of house lots from exterior roads and abutting
properties shall be minimized by the use of changes in topography,
existing vegetation, or additional landscaping which meet the landscaping
requirements of these provisions.
D.
House lots shall generally be accessed from interior
streets, rather than from roads bordering the tract. New intersections
with existing public roads shall be minimized. Although two accessways
into and out of subdivisions containing 20 or more dwellings are generally
preferable, proposals for more than two entrances onto public roads
shall be discouraged if they would unnecessarily disrupt traffic flow
or negatively impact the environment.
A.
Common driveways shall be at least 16 feet wide. Common
driveways shall be constructed in accordance with the driveway specifications
adopted by the Town of Ghent. Common driveways shall also be subject
to a maintenance agreement between the owners of all lots using same,
which maintenance agreement shall be reviewed and approved by the
Planning Board or the Attorney for the Town.
B.
Conservation subdivision streets shall meet the Town
Roadway Specifications. Regardless of the street design employed,
the applicant shall demonstrate and the Planning Board shall find
that emergency services access is adequate for the number of dwellings
proposed.
C.
Whenever appropriate, street systems should produce
vistas of open space in accordance with the conservation emphasis
of the conservation subdivision design and to positively contribute
to the Town's open space goals.
D.
Street trees may be required, depending upon the open
or wooded character of the parcel.
E.
Roadways shall be designed so as to minimize traffic
speeds.
F.
The Planning Board shall consider the potential fiscal
impacts on the Town's resources for all streets, including required
drainage facilities, landscaping and other access-related features.
If the Planning Board identifies a potential fiscal impact, as a condition
of subdivision approval, the Planning Board may require the formation
or extension of a special improvement district(s) pursuant to Articles
12 and 12-a of New York State Town Law or other mechanism acceptable
to the Planning Board, such as formation of a homeowners' association.
The preferred way of protecting open space is
for the applicant to provide deed restrictions acceptable to the Town
Attorney. Conservation easements will also be considered in a case
where same are transferred to a conservation organization or to a
homeowners' association acceptable to the Town. In general, a conservation
easement will not be given to the Town of Ghent unless special circumstances
are present as determined by the Town Board. However, regardless of
how open space is permanently preserved, it is required that the Town
be granted third-party enforcement rights to enforce the terms of
all restrictions, easements or other legally binding instruments providing
for open space. Such provisions shall include that the Town shall
be entitled to reimbursement for all costs, expenses and attorney's
fees incurred in connection with such enforcement, to be collected
from the party against whom enforcement is sought. Where restrictions
are set forth as the method to preserve open space, the Planning Board
may require the developer to create a homeowners' association whereby
open space land and common facilities shall be held in common ownership
by such homeowners' association, subject to all of the provisions
for homeowners' association set forth in New York State law and regulations.
In addition, the following regulations shall be met:
A.
The applicant shall provide the Town with a description
of the organization of the proposed association, including its bylaws,
and all documents governing ownership, maintenance, and use restrictions
for common land and facilities.
B.
The proposed association shall be established by the
owner or applicant and shall be operating (with financial subsidization
by the owner or applicant, if necessary) before the sale of any dwelling
units in the development.
C.
Membership in the association shall be mandatory for
each property owner within the subdivision and successive owners in
title with voting of one vote per lot or unit, and the subdivider's
control, therefore, passing to the individual lot/unit owners on sale
of the majority of the lots or units.
D.
The association shall be responsible for maintaining
adequate liability insurance, payment of local taxes and maintenance
of open space land, recreational facilities and other commonly held
facilities.
E.
The bylaws shall confer legal authority on the association
to place a lien on the real property of any member who falls delinquent
in his or her dues. Such dues shall be paid with the accrued interest
before the lien may be lifted.
F.
Written notice of any proposed transfer of common
facilities by the association or the assumption of maintenance for
common facilities must be given to all members of the association
and to the Town not less than 30 days prior to such event.
G.
The association shall have adequate resources to administer,
maintain, and operate such common facilities, and the Planning Board
shall have the authority to require a bond or other security to ensure
compliance with these requirements.
H.
The Planning Board may waive the requirement for the
creation of a homeowners' association in a case where the applicant
demonstrates by clear and convincing evidence that there is an adequate
way to enforce the proposed deed restrictions, and provide for the
maintenance and preservation of the open space areas without the need
for a homeowners' association.
Unless otherwise agreed to by the Planning Board,
the cost and responsibility of maintaining common open space and facilities
shall be borne by the homeowners' association, conservation organization
or private owner. The Planning Board shall have the authority to require
a bond or other security to ensure proper maintenance of open space
and the facilities located on the subject parcel.
The Town of Ghent encourages shared or community
sanitary sewage disposal systems for conservation subdivisions. Such
systems may be located in the required open space lands such as on
conservation meadows, village greens, and active or passive recreation
areas, provided such areas are not paved or covered with other impervious
surfaces. Sanitary sewage disposal systems of an individual nature
may also be located within or extend into required open space areas.
Regardless of the type of subsurface sewage disposal methods employed,
all required separation distances shall be observed and the ownership
and maintenance responsibilities associated therewith shall be clearly
defined in agreements submitted for approval as part of the subdivision
application. No application shall be approved that does not provide
lot buyers with both the legal authority and the responsibility, individually
or collectively, to maintain all sewer facilities on a continuing
basis. This may include the creation of a special district under Articles
12 and 12-a of New York State Town Law.
The Planning Board shall require the applicant
to set forth on the approved subdivision map, a note or notes setting
forth all covenants, conditions and restrictions relating to the subdivision,
including but not limited to all provisions required for the protection
and maintenance of the open space areas. All such covenants, conditions
and restrictions shall also be set forth in a document which shall
be recorded in the Columbia County Clerk's office at the same time
that the approved subdivision map is filed, and this shall be a requirement
for approval of the subdivision.
