This chapter is entitled the "Wetlands and Watercourses
Law."
It is the intent of the Town of Greenburgh to
control, protect, preserve, conserve and regulate wetlands, watercourses
and adjacent (buffer) areas within the Town so as to not hinder the
benefits set forth in the legislative findings. Activities in and
around wetlands, watercourses and their buffer areas must conform
with all applicable building codes, sediment control regulations,
and other regulations, so that such activities do not threaten public
safety, the natural environment, or cause nuisances by:
A. Impeding flood flows, reducing flood storage areas
or destroying storm barriers, thereby resulting in increased flood
heights, frequencies, or velocities on other lands;
B. Increasing water pollution through location of domestic
waste disposal systems in wet soils; inappropriate siting of stormwater
control facilities; unauthorized application of fertilizers; pesticides;
herbicides and algaecides; disposal of solid wastes at inappropriate
sites; creation of unstabilized fills; or the destruction of wetland
soils and vegetation serving pollution and sediment control functions;
D. Decreasing breeding, nesting, and feeding areas for
many species of waterfowl and shorebirds, including those rare and
endangered;
E. Interfering with the exchange of nutrients needed
by fish and other forms of wildlife;
F. Decreasing habitat for fish and other forms of wildlife;
G. Adversely altering the recharge or discharge functions
of wetlands, thereby impacting ground water or surface water supplies;
H. Significantly altering the wetland hydroperiod and
thereby causing either short- or long-term changes in vegetational
composition, soils characteristics, nutrient recycling, or water chemistry;
I. Destroying sites needed for education and scientific
research, such as outdoor biophysical laboratories, living classrooms,
and training areas;
J. Interfering with public rights in navigable waters
and the recreation opportunities provided by wetlands for fishing,
boating, hiking, bird watching, photography, camping, and other passive
uses; or
K. Destroying or damaging aesthetic and property values,
including significant public vistas.

MAJOR PROJECT (OR PROJECTS)
Any activity or activities which require a permit under this
chapter, where the approval authority is the Planning Board. In situations
where multiple applications are involved for a specific project, if
at least one activity constitutes a "major project," as defined herein,
then each proposed activity for each multiple application concerning
such specific project shall be treated as a major project, notwithstanding
anything contained herein to the contrary.

280-10 when the applicant has demonstrated that either losses or impacts to the wetland or wetland buffer are necessary and unavoidable and have been minimized to the maximum extent practicable.
PERMIT
That form of written Town approval required by this chapter
for the conduct of a regulated activity within a wetland, watercourse
or wetland/watercourse buffer.
POLLUTION
Any harmful thermal effect or the contamination or rendering
unclean or impure of any wetland or waters by reason of erosion, or

location on or in the ground or attachment to something having location
on the ground, including but not limited to buildings, tennis courts,
and swimming pools.
UPLAND SPECIES
Plant species that, under natural conditions, almost always
occur in uplands at an estimated probability of 99% or greater. The
less-than-one-percent probability of upland species occurring in wetlands
is attributed to unnatural circumstances (i.e., occurrences that are
the result of human-induced disturbances and transplants). Upland
species UPL for New York State are listed in "Wetland Plants of the
State of New York 1986," published by the U.S. Fish and Wildlife Service
in cooperation with the National and Regional Wetland Plant List Review
Panels and as updated from time to time.
VERNAL POOL
An open area of surface water formed in a shallow basin within
an upland that retains a minimum depth of six inches for three to
four months during the growing season (usually March through June)
and contains amphibians (adults, egg masses, or larval stages) during
the growing season. Vernal pools are devoid of fish and are the exclusive
breeding habitats of several amphibians that are becoming increasingly
rare throughout the northeast.
WATERCOURSE
Any natural or artificial, intermittent, seasonal or permanent,
and public or private water body or water segment. A water body is
intermittently, seasonally or permanently inundated with water and
contains a discernible shoreline and includes ponds, lakes and reservoirs.
A watercourse includes rivulets, brooks, creeks, streams, rivers and
other waterways flowing in a definite channel with bed and banks and
usually in a particular direction.
WATER TABLE
The zone of saturation at the highest average depth during
the wettest season.
WETLAND
All areas that comprise hydric soils and/or are inundated
or saturated by surface or groundwater at a frequency and duration
sufficient to support, and that under normal circumstances do support,
a prevalence of hydrophytic vegetation as defined by the Corps of
Engineers Wetlands Delineation Manual (Environmental Laboratory Technical
Report Y-87-1). Wetland areas include vernal pools, wet meadows, marshes,
swamps, bogs and similar wet areas.
WETLAND INSPECTOR
The administrative official appointed by the Town Board to
fulfill the responsibilities set forth in this chapter and having
special knowledge by reason of education and work related to the identification,
delineation, functional assessment and management of wetlands, including
a detailed knowledge of wetland flora and fauna and wetland hydrology
to a degree acceptable to the approval authority.
WETLAND PLANTS OF THE STATE OF NEW YORK
Those plant species listed in the National List of Plant
Species That Occur In Wetlands: Northeast (1988), that are classified
as facultative, or facultative wetland, obligate wetland species developed
by the U.S. Department of the Interior, Fish and Wildlife Service,
for the National Wetland Inventory, as amended and updated from time
to time.
WETLAND SCIENTIST
A person having specialized or expert knowledge of the physical,
chemical and biological sciences related to the identification, delineation
and structural and functional ecology of wetlands and associated upland
communities, including flora and fauna; and of methods to delineate
and describe wetland and watercourse resources, communities and habitats.
This person must possess a minimum of two years' field experience
in wetland/watercourse delineation and wetland/watercourse report
preparation and must hold at least a bachelors degree, with a minimum
of 30 semester hours (credits), or equivalent, in biology, physical
science and chemistry, with a minimum of eight semester hours (credits),
or equivalent, in botany, including field identification of animal
and plant species. Individuals who do not meet the above minimum qualifications
but who possess at least 10 years' experience identifying and mapping
native vegetation are qualified if they have completed at least 12
semester hours (credits), or equivalent, in botany, including field
identification of animal and plant species.
WETLAND/WATERCOURSE BUFFER
The area of land extending 100 feet horizontally away from
and parallel to the outermost boundary of a wetland and/or point of
mean high water of a watercourse. The wetland/watercourse buffer may
be greater than 100 feet where designated by either the Commissioner
of the New York State Department of Environmental Conservation or
the local approval authority. The wetland/watercourse buffer provides
several ecological benefits to the wetlands/watercourse and some degree
of protection from human encroachment associated with development.
The wetland/watercourse buffer shall be subject to the regulations
for wetlands as defined in this chapter.
The Planning Board shall either grant, conditionally
grant or deny a permit application within 60 days of the close of
the public hearing; provided, however, that the Planning Board has
whatever additional information or documentation it required, the
Planning Board shall then render its decision within 60 days of its
receipt of such matter.
A. In granting, denying, or conditioning any permit, the Planning Board shall evaluate wetland and watercourse and adjacent (buffer) area functions and the role of each, as the case may be, in the hydrologic and ecological system in which it is part, and shall determine the impact of the proposed activity upon public health, safety and welfare, flora and fauna, water quality, and additional wetland and watercourse functions listed in §
280-2 of this chapter. Regardless of the level of the impact of the proposed activity, avoidance of any direct or indirect impacts shall be the primary criteria used to judge the appropriateness of the action. The Planning Board shall consider the following factors, and shall issue written findings with respect to:
(1) The overall direct and indirect impact(s) of the proposed activity, and existing and reasonably anticipated similar activities, upon neighboring land uses and wetland, watercourse and adjacent (buffer) area functions as set forth in §
280-2 of this chapter, including but not limited to the:
(a)
Infilling of a wetland, watercourse or other
modification of natural topographic contours;
(b)
Disturbance or destruction of natural flora
and fauna;
(c)
Influx of sediments or other materials causing
increased water turbidity or substrate aggradation;
(d)
Removal or disturbance of wetland or watercourse
soils;
(e)
Reduction in wetland or watercourse ground or
surface water supply;
(f)
Interference with wetland or watercourse water
circulation;
(g)
Changes in the amount or type of wetland or
watercourse nutrients;
(h)
Physical and chemical changes to the wetland
or watercourse water supply; and
(i)
Destruction of natural aesthetic values;
(j)
Reduction in public recreational or educational
use and access; and
(k)
Impact to, and alteration or disturbance of
adjacent (buffer) areas associated with wetlands and watercourses.
(2) Any existing wetland, watercourse and adjacent (buffer)
area impact(s) and the cumulative effect of reasonably anticipated
future activities in the wetland, watercourse or adjacent (buffer)
area subject to the application;
(3) The impact of the proposed activity and reasonably
anticipated similar activities upon flood flows, flood storage, storm
barriers, shoreline protection, and water quality;
(4) The potential effect of flooding, erosion, hurricane
winds, soil limitations, and other hazards, and possible losses to
the applicant and subsequent purchasers of the land;
(5) The adequacy of water supply and waste disposal for
the proposed use;
(6) Consistency with federal, state, county and Town comprehensive
land use plans, and regulations;
(7) The availability of preferable or environmentally
compatible alternative locations on the subject parcel; and
(8) The demonstration by the applicant that any direct
and indirect impact(s) are necessary and unavoidable and have been
minimized to the maximum extent practicable for the purposes of this
chapter. Wetland, watercourse and adjacent (buffer) area impacts will
be deemed necessary and unavoidable only if the applicant satisfies
all of the following criteria as determined by the Planning Board:
(a)
The proposed activity is compatible with the
public health and welfare.
(b)
There is no reasonably feasible on-site alternative
to the proposed activity, in the judgment of the Planning Board, including
reduction in density, change in use, revision of road and lot layout,
revision in the location of buildings, structures, driveways and other
site construction and land-altering activities and/or related site
planning considerations, that could otherwise reasonably accomplish
the applicant's objectives.
(c)
There is no reasonably feasible alternative
to the proposed activity on another site or site location that is
not a wetland, watercourse or adjacent (buffer) area as defined herein.
B. The approval authority must deny a permit if:
(1) The applicant has not demonstrated that all reasonable
alternatives have been explored; that reasonable alternatives exist
which could avoid or reduce potential losses or impacts to the wetland,
watercourse or adjacent (buffer) area; or that any unavoidable losses
or impacts to wetlands, watercourses, and adjacent (buffer) areas
have not been minimized to the maximum extent practicable.
(2) The proposed activity may threaten public health,
safety or welfare; results in fraud, causes nuisances, impairs public
rights to the enjoyment and use of public lands and waters; threatens
a special concern, rare or endangered plant or animal species; violates
pollution control standards; or violates any other Town, state, city
or federal regulations or laws; or
(3) Both the affected landowner and the local government
have been notified by a duly filed notice in writing that the state
or any agency or political subdivision of the state is in the process
of acquiring the wetland, watercourse or adjacent area by negotiation
or condemnation with the following provisions:
(a)
The written notice must include an indication
that the acquisition process has commenced, such as that an appraisal
of the property has been prepared or is in the process of being prepared.
(b)
If the landowner receives no offer for the property
within one year of the permit denial, this prohibition shall lapse.
If its negotiations with the applicant are broken off, the state or
any agency or political subdivision must, within six months of the
end of negotiation, either issue its findings and determination to
acquire the property pursuant to § 204 of the Eminent Domain
Procedure Law or issue a determination to acquire the property without
public hearing pursuant to § 206 of the Eminent Domain Procedure
Law, or this prohibition shall lapse.
C. The approval authority shall give consideration to
activities that must have a shoreline or wetland location to function
and that will have as little impact as possible upon the wetland,
watercourse and/or the watercourse/wetland adjacent (buffer) area.
In general, permission will not be granted for dredging or ditching
solely for the purpose of draining wetlands or watercourses, controlling
mosquitoes, creating ponds, constructing industrial facilities, providing
soil and dump sites, or building roads, driveways or buildings or
structures that may be located elsewhere. All reasonable measures
must be taken to minimize all direct and indirect impacts upon the
wetland, watercourse and adjacent (buffer) area.
D. The Planning Board shall require preparation of a mitigation plan by the applicant pursuant to §
280-10 when the Planning Board has determined that all alternatives have been explored and that wetland, watercourse and buffer impacts are necessary and unavoidable and have been minimized to the maximum extent practicable. In the evaluation of the least environmentally damaging practicable alternatives, mitigation may be used as a means of reducing environmental impacts; a mitigation wetland is designed to replace lost wetland acreage and functions.
No permit granted pursuant to this chapter shall
remove an applicant's obligation to comply in all respects with the
applicable provisions of any other federal, state, or Town law or
regulation, including but not limited to the acquisition of any other
required permit or approval.
All permit application and review fees and escrow deposits shall be in an amount set forth in the fee schedule established by resolution of the Town Board and in accordance with Chapter
230 of the Town Code.
In order to carry out the purposes and provisions
of this chapter, and in addition to the powers specified elsewhere
in this chapter, the approval authority shall have the following powers:
A. To do any and all things necessary or convenient to
carry out the policy and intent of this chapter; and
B. To consult or contract with expert persons or agencies
in reviewing a permit application; and
C. To hold hearings and subpoena witnesses in the exercise
of its powers, functions, and duties provided for by this chapter.
Any determination, decision or order of the
approval authority may be judicially reviewed by the applicant or
any other aggrieved party by the commencement of an action pursuant
to Article 78 of the Civil Practice Law and Rules of the State of
New York within 30 days after the date of the filing of the determination,
decision or order of such approval authority with the Clerk of the
Town of Greenburgh and/or County.
