RE:
WETLAND REPORT
Town of Waterford, CT
150 GREAT NECK ROAD
PARCEL ID 152-0264000
WATERFORD, CONNECTICUT
Dear Mr. Thibeault,
At Killingly Engineering Associates, LLC request, I completed a field delineation of the
Connecticut jurisdictional freshwater inland wetland and watercourse boundaries at the
above referenced 0.918-acre residential parcel located at 150 Great Neck Road (Rte. 213)
in Waterford, Connecticut.
I also prepared this letter report to detail an evaluation of the on-site wetland resources
and the development impacts that potentially could result from the proposed plans to
construct a new single family residence and associated site improvements located in the
available uplands positioned in the southeast portion of the site. I offer the following
comments for consideration in evaluating the proposed project.
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.

Soil Evaluations
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 Waterford
or any portion thereof not regulated pursuant to sections 22a-28 through 22a-35,
inclusive, of the Connecticut General Statutes. Intermittent watercourses are defined as
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 April 22, 2026. 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 within the survey area.
Those areas meeting the wetland criteria noted above were marked in the field with
sequentially numbered pink wetland delineation flagging labeled 1 through 12 and 1A
through SA. The provided wetland sketch illustrates the approximate wetland locations
and corresponding flag series, please be advised this sketch is subject to refinement once
traditionally located and mapped by a Licensed Land Surveyor and adopted by the Town.
The vacant site is located on an undeveloped wooded parcel between the Perkins Farm
Road open space to the north and a developed residential lot at 152 Great Neck Road. A
wetland pocket located along the roadside in the northwest corner site drains east down
the north property line where it flows into to a larger forested wetland system that covers
the bulk of the low-lying level eastern side of the property. There is an upland area of
approximately .30 acres in the southeastern corner of the lot. Overall, the site drains west
to east and falls within the Southeast Shoreline subregional drainage basin (CTDEEP
#2000).
The wetland vegetation community includes:
‘Trees: Red Maple, yellow birch, silver maple, American elm
Shrubs: Highbush blueberry, sweet pepperbush, green briar, spicebush, Japanese
barberry, multiflora rose
Herbaceous: Tussock sedge, skunk cabbage, sensitive fern and sphagnum moss,
The above is not an exhaustive list, but a sample of commonly encountered vegetation
that characterizes the on-site wetland community. Representative photos of the site are
attached below.
SOIL SURVEY
The soils identified on-site are a refinement of the Natural Resources Conservation
Service (NRCS) Websoil Soil Survey.

Soil Evaluations
Wetland Soils
The primary wetlands soil series along the flagged wetland boundary are classified as G)
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.
Upland Soils
The soils around the proposed homesite are generally level and are classified as
Woodbridge fine sandy loams. Because of the underlying dense till Woodbridge soil has
perched water table resulting in slow subsurface permeability rates.
PROPOSED ACTIVITIES
The applicant is proposing to develop a new single-family residential dwelling and
associated appurtenances on the southeastern portion of the overall lot. The new proposed
dwelling would be accessed by a standard 12-foot wide gravel driveway and will be
serviced by buried utilities including a municipal sewer and a waterline. Grading for the
new driveway has been located so there will be no direct impacts to the wetland
resources,
Prior to construction erosion and sediment control barriers installed at the limits of
disturbance. These site protection measures will be maintained throughout construction
and will be removed once the site is stabilized. Clearing limits have been minimized to
the extent it is practical to develop the lot. At the limits-of-disturbance a row of 20
individual “deer resistant” green giant arborvitaes will boarder the wetlands which will be
backstopped by a split rail fence to mitigate future encroachments.
The site work proposed will not significantly impact on the wetlands and will utilize the
100-foot upland review area to support the dwelling. Details of the location and extent of
the proposed regulated activities are illustrated on the subject site plans.
WETLAND and UPLAND REVIEW AREA RESOURCES
The property is wooded, dominated by a mixed hardwood forest overstory with thick
patches of green briar in the understory. The on-site soils originated from several sources
of parent material including glacial melt-out till and lodgment glacial till. The site is not
located in an aquifer protection area. The wooded swamp forms a feeder stream which is
a headwater that drains to the south towards Goshen Cove. The on-site wetlands are
classified as a freshwater, palustrine, seasonally flooded, forested wetland (Red Maple
dominated).
The site is not located in aquifer protection zone, and a review of FEMA Flood Mapping
indicates that there is no FEMA 100-year flood plain is located on the property. Lastly,

the site is not located in a Connecticut Department of Energy and Environmental
Protection (CTDEEP) designated Natural Diversity Data Base (NDDB) area per the
publicly available December 2025 Town of Waterford NDDB.
VERNAL POOL EVALUATION
The forested wetland was evaluated for vernal pool characteristics. At the time of
inspection on April 22, 2026:
e
The wetland exhibited seasonal flooding to saturation, with isolated areas of
shallow standing water (approximately 4-8 inches in depth).
e
No amphibian egg masses (wood frog or spotted salamander) or other breeding
indicators were observed.
Based on regional experience and ongoing monitoring of multiple confirmed vernal pools
by Ian Cole, LLC at the time of the April 22, 2026, site inspection:
¢
The wood frog breeding period had concluded, and
e
The spotted salamander breeding period was near completion at the time of
inspection.
Despite this timing, the observed hydrologic conditions are not sufficient to support
vernal pool function, for the following reasons:
e
While micro-topography is widely present, ponding is too shallow, discontinuous,
and limited in spatial extent to provide the necessary hydroperiod to reliably
sustain larval development in most years,
e
The wetland is expected to dry relatively quickly following leaf-out, further
limiting suitability.
Therefore, I concluded that the forested wetland on-site does not meet functional criteria
for vernal pool habitat, the wetland’s hydroperiod neighboring to the proposed
development is not long enough nor are there sufficient pools deep enough to sustain
breeding habitat for three months in the early spring growing season.
WETLAND FUNCTIONS AND VALUES ANALYSIS
The assessment of wetlands and watercourses functions and values is based on the US
Army Corps of Engineers’ (USACE) The Highway Methodology
Workbook, A
Descriptive Approach (1995) methodology, and on best professional judgment.
The functions and values of the wetland corridor is summarized in Table 1. The Highway
Methodology recognizes 13 separate wetland functions and values. The degree to which
a wetland provides each of these functions is determined by one or more of the following
factors: landscape position, substrate, hydrology, vegetation, history of disturbance, and
size. Each wetland may provide one or more of the listed functions at significant levels.
The determining factors that affect the level of function provided by a wetland can often
be broken into two categories. The effectiveness of a wetland to provide a specified
function is generally dependent on factors within the wetland whereas the opportunity to
provide a function is often influenced by the wetland’s position in the landscape as well
as adjacent land uses. For example, a depressed wetland with a restricted outlet may be

considered highly effective in trapping sediment due to the long residence time of runoff
water passing through the system. If this wetland is located in gently sloping woodland,
however, there is no significant source of sediment in the runoff therefore the wetland is
considered to have a small opportunity of providing this function.

For context of evaluating the wetland features it is important to acknowledge that the
upper edge of the wetlands adjacent to the road which will be impacted are not as highly
functioning in comparison to the interior / downgradient portion of the wetland and
where the watercourse hydrology is more persistent throughout the year and there are
pockets of organic soils accompanied by a diversity of wetland vegetation; it is within
this interior downstream wetland zone the system is more sensitive and includes the more
beneficial part of the overall wetland system.
The wetlands in the front of the parcel that will be filled with the driveway entrance have
functions and values that are limited due to the narrow confines of the wetland, prolific
growth of invasive species reducing the ecological integrity, lack of open water, lack of
deep organic soils or thick topsoil to provide residency and retention of water, pollutants
and sediments and private ownership of the site. The wetlands functions will not be
significantly impacted from the fill placed at the edge of the wetland to accommodate the
driveway entrance apron.

IMPACT ASSESSMENT.
No wetlands will be directly impacted from the proposed activities. Staked bales of hay
at grade will be installed prior to the start of construction and will be maintained until the
site is stabilized. The site will be sewered so dissolved nitrates and pollutants will not be
an issue. The development will leave the bulk of the property wooded including nearly all
of the sensitive wetland features in the rear of the lot in their existing natural undistrubed
state.
The proposed activities in the upland review area will not change the overall character of
the wetlands and watercourses in a negative or adverse way. Post development the
watercourse will still maintain the same capacity to convey stormwater and seasonal
groundwater runoff. Due to the extents of the wetlands and limited uplands available on-
site requires unavoidable activities within the 100-foot upland review area. All proposed
activities are in the upland review area.
Stormwater runoff and grading has been designed to promote sheet flow and infiltration
into the ground. There will be no substantial changes to hydrology or watershed of the
wetland feature. There will be no changes in the wetland vegetation community or overall
species composition of the wetlands as a result of the proposed development(s). The
applicant will
mitigate
construction related
impacts by implementing
standard
construction Best Management Practices (BMPs) and conforming to permit conditions.
The proposed activities are not likely to have a significant effect on the environment for
the following reasons:
1.
There is no filling of any inland wetland and/or watercourses with this proposal.
2. The project will not substantially change the natural channel or negatively inhibit
the natural dynamics of the wetland system.
3. The proposed activities within the uplands will not diminish the capacity of the
wetland. The wetland will provide the same wetland functions and values post
development.
4. The erosion and sediment controls will protect the environment from the proposed
activities and if appropriately installed, monitored and maintained will not likely
cause
or have
the
potential
to
cause
substantial turbidity, siltation or
sedimentation in a wetland or watercourse.
5. No activities will cause a substantial diminution of flow of a natural watercourse
or groundwater levels of the regulated area.
6. The site development will have public sewer and water utilities as well as health
department approval and is unlikely to cause or have the potential to cause
pollution of the wetland.

7, The wetland features are not unique, nor do they provide demonstrable scientific
or educational value.
In considering feasible and prudent alternatives, the current proposal respects the
integrity of the environment, has no direct wetland impact, and implements best
management practices that will protect the adjacent resource areas. There are no less
impactful ways to access the properties and therefore, the proposal is the most feasible
and prudent alternative for the development of this property, giving due consideration to
balancing the protection of the inland wetlands and watercourses while fostering
reasonable development and use of the site.
In my professional opinion there will be no significant adverse impacts resulting from the
development of the project as currently proposed. The activities required to facilitate the
development will not result in any loss of function to wetlands and watercourses. Post
development the wetlands and watercourses will still have the same ability to perform the
existing functions currently provided. Furthermore, the regulated activities depicted on
the subject site development plans are materially and substantially similar in comparison
to adjacent developed parcels. As a result, environmental effects will be minor,
temporary, and highly localized.
