Wetland Delineation Report 
1. 
INTRODUCTION 
On behalf of the applicant, Hendels, Inc., SLR International Corporation (SLR) investigated a 35.6-acre site 
to locate and delineate wetlands and watercourses on the site, and to assess existing wetland functions 
and values.  Wetland resources areas were delineated by SLR soil scientists on March 22, 2017.  
 
The project site is an undeveloped piece of land with frontage on Hartford Turnpike across from Cross 
Road. The site is forested with areas of steep slopes and rocky outcrops. There is a perennial watercourse 
north of the site and a cleared right-of-way to the east. A gas station and convenience store abut the 
property on the northwest side. There is another commercial development to the south. One palustrine, 
forested slope wetland exists in the southern portion of the subject parcel. No watercourses were 
observed on site.

GENERAL SITE DESCRIPTION 
The subject parcel comprises 35.6 acres located in a moderately settled commercial and residential area 
of north-central Waterford (Figure 1). The property is undeveloped and forested and contains 1,850 linear 
feet of frontage on Hartford Turnpike (Route 85).  Utility corridors exist to the east, south, and north of 
the site. A gas station and convenience store abut the site to the northwest.  Hartford Commons exists 
south of the site past the utility corridor. 
 
The property occupies the top and southern flank of two drumloidal features.  Elevations range from 150 
feet in the northern and eastern portions of the site to 100 feet in the southwestern section.  Soils of the 
site are derived from glacial till.  The majority of the site is composed of upland deciduous forest, with 
one forested wetland area in the southern portion of the site.   
A review of historical topographic maps reveals the site has remained relatively undeveloped for the last 
century, though grading for and maintenance of the bordering utility right-of-way have likely introduced 
some disturbance along the parcel boundaries. Current CT-DEEP Natural Diversity Database (NDDB) 
mapping from December 2020 shows a small area in the western portion of the parcel is within a mapped 
habitat area for state-listed threatened, endangered, or special concern species associated with Jordan 
Brook.   
The site is located within a 4.7 square mile local watershed associated with Jordan Brook, which flows 
north to south approximately 250 feet west of the parcel boundary. Jordan Brook is a first-order, perennial 
stream with its headwaters in northern Waterford east of Lake Konomoc, approximately 1.75 miles north 
of the subject property. The watercourse has been rated by CT DEEP as Class A and has a Federal 
Emergency Management Agency (FEMA) regulated 100-year floodplain and floodway that are outside of 
the subject parcel. From the general area of the project site, Jordan Brook flows south approximately 5.25 
miles to discharge to Long Island Sound via Jordan Cove in southern Waterford.

WETLAND DELINEATION 
Wetland boundaries on site were delineated by William Root, registered soil scientist, and Kelly Kerrigan, 
soil scientist in training, both with Milone & MacBroom, Inc. (now SLR) on March 22, 2017.  
 
On the day of the investigation, weather conditions were clear and sunny and soils were frost free.  
 
Wetlands on site consist of approximately 5.5 acres of palustrine forested slope wetland, comprising 15% 
of the total site area (Figure 2). The wetland area is diffuse, occupying depressional areas within the 
southern portion of the site, and is bound to the west by Route 85 and to the east by a maintained 
transmission corridor. Vegetation in the wetland consists of a red maple (Acer rubrum) and black birch 
(Betula lenta) canopy, with saplings of American beech (Fagus grandifolia) and an understory comprised 
of Christmas fern (Polystichum acrostichoides), skunk cabbage (Symplocarpus foetidus), and tussock sedge 
(Carex stricta). The wetland surface is strewn with medium to large mossy boulders, and on the day of the 
site survey a high water table was present with several inches of standing water filling open depressions 
and the spaces between boulders. The wetland is primarily supported by this seasonal high water table 
and groundwater discharge, though surface runoff features and rills were also observed connecting 
segments of the wetland. No vernal pools or other special wetland types were located on site during the 
investigation.  
 
No perennial or intermittent watercourses were delineated on site.  Jordan Brook flows approximately 
250 feet west of the site boundary.  
3.1 
REGULATORY DEFINITIONS 
 
The Inland Wetlands and Watercourses Act (Connecticut General Statutes §22a-38) defines inland 
wetlands as "land, including submerged land...which consists of any soil types designated as poorly 
drained, very poorly drained, alluvial, and floodplain."  Watercourses are defined in the act as "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 state or any portion thereof."   
 
Upland Review Area, per the Town of Waterford Inland Wetlands and Watercourses Regulations, includes 
any area within 100 feet of the boundary of wetlands and/or watercourses. 
 
3.2 
METHODOLOGY 
 
In accordance with the principles and practices noted in the United States Department of Agriculture 
(USDA) publication Soil Survey Manual (1993), a second-order soil survey was completed at the subject 
site in June 2018.  The classification system of the National Cooperative Soil Survey was used in this 
investigation.  Soil map units identified at the project site generally correspond to those included in the 
Soil Survey of the State of Connecticut (USDA, 2005).

June 2021 
Wetland Delineation Report 
Wetland determinations were completed based on the presence of poorly drained, very poorly drained, 
alluvial, or floodplain soils and submerged land (e.g., a pond).  Soil types were identified by observation 
of soil morphology (soil texture, color, structure, etc.).  To observe the morphology of the property's soils, 
test pits and/or borings (maximum depth of 2 feet) were completed at the site.  
 
Intermittent watercourse determinations were made based on the presence of a 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 a duration 
longer than a particular storm incident, and C) the presence of hydrophytic vegetation.  
 
Wetland boundaries were demarcated (flagged) with pink surveyor's tape (hung from vegetation) or small 
flags (on wire stakes) that are generally spaced a maximum of every 50 feet.  Complete boundaries are 
located along the lines that connect these sequentially numbered flags.  The wetland boundaries are 
subject to change until adopted by local, state, or federal regulatory agencies.  Wetland areas are depicted 
on Figure 2 and shown as wetland flags wr-1 through wr-54, and wx-1 through wx-24, wx-50 through wx-
59, wx-80 through wx-86, and wx-100 through wx-117.  
3.3 
SOIL MAPPING 
 
Five soil map units were identified on the property according to the Natural Resources Conservation Service 
(NRCS) Web Soil Survey (one wetland and four upland; Figure 3).  Each map unit represents a specific area 
on the landscape and consists of one or more soils for which the unit is named.  Other soils (inclusions that 
are generally too small to be delineated separately) may account for 10 to 15 percent of each map unit.  The 
mapped units are by name, symbol, and typical characteristics (parent material, drainage class, high water 
table, depth to bedrock, and slope) (Table 3-1).  These characteristics are generally the primary 
characteristics to be considered in land use planning and management.  A complete description of each soil 
map unit can be found in the Soil Survey of the State of Connecticut (USDA, 2005).

CONCLUSION 
SLR wetland scientists visited the site at 969 Hartford Turnpike in Waterford to delineate boundaries and 
assess functions and values of onsite wetlands across the 35.6-acre forested site. The site is relatively 
undisturbed, surrounded largely by upland deciduous forest. One palustrine forested wetland system, 
occupying approximately 5.5 acres in the southern portion of the site, was identified and delineated.  No 
watercourses were delineated on the site.
