RE: WETLAND AND WATERCOURSE DELINEATION REPORT
47 SHARP HILL ROAD
MAP 23, LOT 63
19.13 +/- ACRES
MONTVILLE, CONNECTICUT
Dear Mr. Faulise:
At Boundaries LLC’s request, I completed a field delineation of the Connecticut
jurisdictional freshwater inland wetland and watercourses located on the 19.13-acre
residential property located on Sharp Hill Road with additional access from cul-de-sac on
Carol Drive in Montville, Connecticut.
DELINEATION METHODOLOGY
The wetland delineation was completed in accordance with the standards of the Natural
Resources Conservation Services (NRCS) National Cooperative Soil Survey and the
definitions of inland wetlands and watercourses as found in the Connecticut General
Statutes, Chapter 440, Sections 22a-36 through 22a-45 as amended. Wetlands, as defined
by the Statute, are those soil types designated as poorly drained, very poorly drained,
floodplain or alluvial in accordance with the NRCS National Cooperative Soil Survey.
Such areas may also include disturbed areas that have been filled, graded, or excavated
and which possess an aquic (saturated) soil moisture regime.
Watercourses means rivers, streams, brooks, waterways, lakes, ponds, marshes, swamps,
bogs, and all other bodies of water, natural or artificial, vernal, or intermittent, public, or
private, which are contained within, flow through or border upon the Town of Montville
or any portion thereof not regulated pursuant to sections 22a-28 through 22a-35,

inclusive, of the Connecticut General Statutes. Intermittent watercourses are defined
permanent channel and bank and the occurrence of two or more of the following
characteristics: (a) evidence of scour or deposits of recent alluvium or detritus, (b) the
presence of standing or flowing water for duration longer than a particular storm incident,
and (c) the presence of hydrophytic vegetation.
WETLAND SURVEY RESULTS
The wetland survey was completed on September 10, 2024. The on-site wetland
delineation examined the upper 20" of the site’s soil profile for the presence of hydric soil
conditions and delineated any wetland and/or watercourse boundaries located on the
parcel. Two areas meeting the criteria above were marked in the field with sequentially
numbed wetland flagging labeled 1-1 through 1-2 and 2-1 to 2-4. The attached wetland
sketch illustrates the approximate wetland locations and corresponding flag series. Please
note this sketch is for high level planning and navigation purposes only and the wetland
boundaries depicted are subject to refinement once traditionally located and mapped.
The subject property is currently vacant, undeveloped and vegetated with a mixed
hardwood forest. The front half of the property was used extensively as pasture and the
forest community is dominated by an early successional forest with a high concentration
of evergreens and cedar trees. The forest community in the rear northern half of the site is
mature woods with a relatively open forest understory in comparison to the front half of
the site. At the peripheral of the property at the northern edge and near southeast corner
are two small, flagged wetland areas. Both flagged wetlands are associated with a
hillside seepage point that spawns the source / headwaters for each respective intermittent
watercourse. Wetland #1 designated by wetland flags 1-1 to 1-9 was flowing at the time
of my field visit and has a more persistent flow and is a larger wetland system in
comparison to the relatively small, more ephemeral nature of Wetland #2 which is
marked in the field by flags 2-1 to 2-4. Both of these wetlands/watercourse features drain
to the east away from the subject property.
The overall wetland vegetation community of the flagged wetlands includes the
following vegetative species but is not limited to:
Trees: Red Maple, yellow birch, American beech.
Shrubs: Japanese barberry, spicebush, multiflora rose, winterberry, high bush blueberry
Herbaceous: skunk cabbage, jewelweed, false hellebore, sensitive fern, marsh fern,
cinnamon fern.
The above is not an exhaustive list, but a sample of commonly encountered vegetation
that characterizes the on-site wetland community. Representative photos are attached.

SOIL SURVEY
The soils identified on-site are a refinement of the Natural Resources Conservation
Service (NRCS) Websoil Soil Survey. The property generally drains from west to east
with moderate slopes ranging from 3% to 15%.
Wetland Soils
The wetlands soils are classified as (3) Ridgebury, Leicester, and Whitman fine sandy
loams. The poorly drained soils along the wetland boundary belong to the Ridgebury and
Leicester soil series. Ridgebury and Leicester soils are found within drainageways and
depressions on glacial till landscapes. Ridgebury and Leicester soils have a seasonal
high-water table at a depth of about 6 inches. Very poorly drained Whitman soils are
found in the lowest lying areas within the interior of the wetlands where the water table is
at the surface thought most of the growing season.
A typical soil profile along the wetland boundary consists of approximately 3”-0” of
intermediately decomposed organic material (Oi), followed by 0”-6” of a thick dark
topsoil horizon (A), underlain by 6-18” of a wet weakly developed grayish subsoil
horizon (Bg) with common redoximorphic features (Common medium distinct strong
brown mottles, masses) ranging from fine sandy loam to very fine sandy loam. This
subsoil is underlain by a saturated sandy loam to fine sandy loam gray substratum (2Cg).
Upland Soils
The upland soils were not examined in great detail except as necessary to delineate the
wetland boundary. The upland soils on the bulk of the property are mapped as
Woodbridge soils. These moderately well-drained fine sandy loam soils are typically
compact in place from dense glacial till deposits and as a result are often associated with
a perched seasonal high watertable and slow permeability rates.

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
