ACTIVITY, PREEXISTING, NONCONFORMING
Those actions and activities occurring within a wetland,
water body, watercourse or their associated buffer areas which were
approved prior to the effective date of this section and for which
the approval has not expired and is still valid. These actions and
activities may not be expanded, changed, enlarged, or altered; or
discontinued for a period of 12 consecutive months without losing
their preexisting, nonconforming status. Preexisting, nonconforming

must be reconstructed within 12 months and be completed within 24
months or lose their preexisting, nonconforming status.

variation in physical or chemical factors of any wetland or watercourse
by reason of erosion, or by any waste or other materials discharged
or deposited therein.
REGULATED ACTIVITY
Those actions and activities occurring within a wetland, water body, watercourse or their associated buffer areas which are not exempted from requiring a wetland permit by §
260-34D of this section and are more specifically listed in §

REGULATED AREA
Wetlands, waterbodies, vernal pools, watercourses and their
associated wetland/watercourse buffer areas as defined in this section.
UCSWCD

VERNAL POOL
Seasonally flooded, isolated pool of standing water that
is devoid of naturally occurring fish and that persist, in a year

essential breeding habitat for certain amphibians, including, but
not limited to, the following species: spotted salamander (Ambystoma
maculatum), marbled salamander (Ambystoma opacum), Jefferson salamander
(Ambystoma jeffersonianum), blue-spotted salamander (Ambystoma laterale),
Northern spring peeper (Hyla c. crucifer), and wood frog (Rana sylvatica).
WATER BODY
Any natural or artificial pond, lake, reservoir, or other
area which usually or intermittently contains water and which has
a discernible shoreline. For the purposes of this chapter, a water
body is also a wetland, and the appropriate wetland buffer area shall
apply. An artificial pond of less than 1/10 of an acre (i.e., 4,356
square feet) shall not be considered a regulated water body, provided
its creation and maintenance does not alter the flow, function or
values of existing waterbodies, wetlands or watercourses.
WATERCOURSE
Any natural, artificial, permanent, seasonal, or intermittent,
public or private water segment, such as rivers, streams, brooks,
or other waterways that are contained within, flow through, or border
on the Town of Woodstock. A watercourse contains a discernible channel,
bed, and/or banks and usually flows in a particular direction. Artificial
water segments, such as swales and ditching shall not be considered
a regulated watercourse, provided they do not discharge directly into
a naturally occurring wetland water body or watercourse.
WATERCOURSE BUFFER AREA
A specified area surrounding a watercourse that is intended
to provide some degree of protection to the watercourse from human
activity or other encroachment associated with development. The watercourse
buffer area shall be subject to the regulations for watercourses as
defined herein and shall be determined by consulting the map entitled,
"Applicable Watercourse Buffers" which is maintained in the office
of the Planning Board and Building Inspector. The buffer area is the
area extending horizontally away from and paralleling the edge of
bank of a watercourse. Buffer widths vary from 30 to 45, 60, 75, 90
or 100 feet (each side) depending on the upstream drainage area and
the slope of the land. The default buffer for all watercourses is
30 feet from the edge of bank.
WATERSHED
The region draining into a river, river system, or other
body of water.
WETLAND AND WATERCOURSE INSPECTOR
The agent appointed by the Town Board, who may or may not
be employed by the Town also as a Building Inspector, charged with
enforcement and permit-processing responsibilities associated with
regulated activities within regulated areas. The determination of
the Wetland and Watercourse Inspector shall be of the same force and
effect and subject to the same laws and regulations as those of the
Building Inspector. The Wetland and Watercourse Inspector must be
certified in basic wetland delineation.
WETLAND BUFFER AREA
A specified area surrounding a wetland, that is intended
to provide some degree of protection to the wetland from human activity
or other encroachment associated with development. The wetland buffer
area shall be subject to regulations and site conditions for wetlands
and watercourses as defined herein. The wetland buffer area shall
consist of the area extending 100 feet horizontally away from and
paralleling the outer wetland boundary limits of a wetland of greater
than 1/10 of an acre (i.e., 4,356 square feet) and 50 feet horizontally
away from and paralleling the outer wetland boundary limits of a wetland
of equal to or less than 1/10 of an acre.
WETLAND DELINEATION
The process by which the boundary or edge of a wetland is
determined. Delineations shall be in accordance with Part IV of the
US Army Corps of Engineers Wetland Delineation Manual (1987) herein
referred to as the Wetland Delineation Manual.
WETLAND DELINEATOR
A person who has demonstrated training and experience in
the identification of wetlands and watercourses, and the use of the
Corps of Engineers Wetland Delineation Manual (January, 1987) including
preparation of federal data forms and federal level wetland delineation
reports. A wetland delineator must have a degree from an accredited
university in a related field and a minimum of two years of continuous
wetland and watercourse delineation experience as set forth above.
WETLAND (FRESHWATER WETLAND)
(1)
All areas that comprise hydric soils and/or are inundated or
saturated by surface water or groundwater at a frequency and duration
sufficient to support, and that under normal circumstances do support,
a prevalence of vegetation typically adapted for life in saturated
soil conditions. For the purposes of this chapter, the term "wetland"
shall refer to freshwater wetlands and shall generally include swamps,
marshes, bogs, vernal pools, and similar areas. Wetlands must have
the following three general diagnostic environmental characteristics:
(a)
Wetlands vegetation. The prevalent vegetation consists of macrophytes
that are typically adapted to areas having hydrologic and soil conditions
as described above. Hydrophytic species, due to morphological, physiological,
and/or reproductive adaption(s), have the ability to grow, effectively
compete, reproduce, and/or persist in anaerobic soil conditions. Indicators
of vegetation associated with wetlands are listed in Paragraph 35
of the Wetland Delineation Manual.
(b)
Wetlands Soil. Soils are present and have been classified as
hydric, or they possess characteristics that are associated with saturated
soil conditions. Indicators of these soils are listed in Paragraphs
44 and 45 of the Wetland Delineation Manual.
(c)
Wetlands hydrology. Wetlands are inundated either permanently
or periodically at mean water depths equal to or less than 6.6 feet,
or the soil is saturated to the surface at some time during the growing
season. Indicators of hydrologic conditions that occur in wetlands
are listed in Paragraph 49 of the Wetland Delineation Manual.
(2)
Regulated wetlands do not include:
(a)
Detention, infiltration and retention basins created as part
of an approved local, state or federal stormwater pollution prevention
plan; or
(b)
An artificial pond of less than 1/10 of an acre (i.e., 4,356
square feet), provided the pond's creation and maintenance does not
alter the flow, function or values of existing waterbodies, wetlands
or watercourses.
WETLAND HYDROLOGY
The sum total of wetness characteristics in areas that are
inundated or have saturated soils to within 18 inches of the surface
for a sufficient duration to support hydrophytic vegetation.
WETLAND PERMIT
That form of written approval required by §
260-34 of this chapter allowing for a specific regulated activity in a regulated area.
