Wetland Summary Letter 2268 – 2284 Route 32 Montville, Connecticut 1
August 23, 2024
RJO’Connell & Associates, Inc. Attn: Roy Smith 80 Montvale Avenue, Suite 201 Stoneham, MA 02180 Re: Wetland Summary Letter 2268-2284 Route 32 Montville, CT Dear Mr. Smith,
A Registered Professional Soil Scientist (RPSS) from Lucas Environmental, LLC (LE) conducted a site investigation on July 19, 2024, to determine if wetland resources or watercourses were present on or near the property located at 2268 – 2284 Route 32 in Montville, Connecticut (i.e., Study Area). Please note that
this effort is specific to wetland resources; it does not evaluate constraints related to local planning or zoning requirements, historical or cultural significance, nor does it evaluate the potential for soil, air, or water
contamination. The wetland investigation was performed in accordance with the Connecticut Inland Wetlands and
Watercourses Act of 1972; Section 404 of the Clean Water Act (33 U.S.C. 1344); the U.S. Army Corp of Engineers (USACE) Wetland Delineation Manual (1987) and the Northcentral and Northeast Regional Supplement (2012); and the Inland Wetlands and Watercourses Regulations of the Town of Montville, Connecticut (effective date October 19, 2017). The site investigation was limited to wetland areas within 100 feet and streams within 200 feet of the Study Area. Areas beyond the scope of the Study Area were not delineated.
1.0 EXISTING CONDITIONS
The Study Area is comprised of three parcels totaling approximately 3.4 acres of land at 2268 – 2284 Route 32 in Montville, Massachusetts (See Figure 1 – USGS Map and Figure 2 – Aerial Map). The parcels are identified as follows:
• 2268 Route 32 (Parcel 106-034) is an approximate 1.43-acre parcel of land which makes up the southern half of the Study Area.
• 2280 Route 32 (Parcel 106-036) is an approximate 0.21-acre parcel of land along Route 32, between parcels 34 and 35.
• 2284 Route 32 (Parcel 106-035) is an approximate 1.72-acre parcel of land which makes up the northern half of the Study Area.
500A Washington Street, Quincy, MA 02169
Wetland Summary Letter 2268 – 2284 Route 32 Montville, Connecticut 2
The Study Area is vacant and vegetated with a dense thicket of early successional plant communities and invasive species such as Norway maple (Acer platanoides), black locust (Robinia pseudoacacia), autumn
olive (Elaeagnus umbellata), burning bush (Euonymus alatus), black cherry (Prunus serotina), fox grape (Vitis labrusca), multiflora rose (Rosa multiflora), Oriental bittersweet (Celastrus orbiculatus) common reed (Phragmites australis), garlic mustard (Allaria petiolata), and poison ivy (Toxicodendron radicans). The Study Area is bounded by Route 32 to the east, residential properties to the north and west, commercial development to the south, and Meadow Lane to the southwest. A review of the Natural Diversity Data Base (NDDB) Areas for Montville indicates that there are no areas of State Listed Species & Significant Natural Communities or Critical Habitats within or near the property (See Figure 3 – Natural Diversity Database Map). According to the July 18, 2011 Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) for New London County, Connecticut, Map Number 09011C0351G, the property is located
within a mapped Zone X Area of Minimal Flood Hazard, which is classified as areas outside the 0.2% annual chance floodplain (500-year floodplain) (See Figure 4 – FEMA Map). Therefore, the property falls outside the 100-year floodplain.
According to the Connecticut Environmental Conditions Online (CTECO) Map Viewer, the site is not
located within an Aquifer Protection Area and does not contain a CT 303(d) Impaired Waterbody.
2.0 ENVIRONMENTAL RESOURCE AREAS
The investigation of wetlands on this site was based on the presence or absence of poorly and very poorly
drained, alluvial, and floodplain soils as defined by the National Cooperative Soil Survey of the Natural Resources Conservation Service (NRCS) of the United States Department of Agriculture (USDA). During the course of the evaluation, reference was made to the NRCS Custom Soil Resource Report (enclosed),
the 1987 “Corps of Engineers Wetlands Delineation Manual” (Department of the Army, Technical Report Y-87-1), the Northeast and Northcentral Regional Supplement v. 2.0 (2012), and the Field Indicators for Identifying Hydric Soils in New England (Version 4). Soil types are identified by observing soil morphology
(soil texture, color, structure, etc.). The following describes the wetlands/watercourses identified within the property. Wetland Determination Data Forms are enclosed. 2.1 Wetland & Watercourse Descriptions
The following describes each of the resource areas identified in the Study Area. Wetland A
Wetland A is an emergent wetland located along the northern property line. It is vegetated primarily with common reed (Phragmites australis), hedge bindweed (Calystegia sepium), multiflora rose (, jewelweed (Impatiens capensis), and fowl grass (Poa palustris). Wetland A was delineated with pink survey tape numbered sequentially from WFA-1 to WFA-14.
500A Washington Street, Quincy, MA 02169
Wetland Summary Letter 2268 – 2284 Route 32 Montville, Connecticut 3
The wetland is located at the bottom of a hillside and likely has formed as it collects surface flows originating from an upgradient stormwater outfall. The outfall conveys untreated and unmitigated
stormwater from Cedar Lane and discharges it down the hillside. The stormwater collects at the bottom of the hill then water dissipates outward over a flat area. As a result, the wetland has accumulated several inches sediment and there is evidence of surface scour and erosion. The wetland is geographically isolated and lacks connectivity and overall function. Soils within the wetland are characterized as Aquents, and consist of an organic rich mineral surface horizon (sand and loamy sand) overlying fine sandy loam. The Aquent soils are characterized by a seasonal to prolonged high ground water table and either support or are capable of supporting wetland vegetation. Aquent soils are recently formed soils which have an aquic moisture regime. The subsoil consists of a depleted matrix and redoximorphic features (i.e., soft masses of iron accumulation in the matrix). The wetland/upland boundary is diffuse and corresponds to a transition to a non-hydrophytic plant community and absence of hydric soils/wetland hydrology. Indicators of wetland hydrology observed include drainage
patterns. 2.2 Soil Map Types
A description of each soil map unit identified in and near the Study Area is presented in the attached NRCS Custom Soil Resource Report (enclosed). The soils in the vicinity of the Study Area are generally consistent with the published data. The soil information for the site includes the following soil map unit:
• 29B – Agawam fine sandy loam, 3-8% slopes;
For further information on these and other soils, please refer to the internet site
http://soils.usda.gov/technical/classification/osd/index.html) and the attached NRCS Custom Soil Resource Report.
3.0 REGULATIONS
Wetlands and watercourses are regulated by both state and federal law each with different definitions and regulatory requirements. Accordingly, the state may regulate waters that fall outside of federal jurisdiction; however, where federal jurisdiction exists concurrent state jurisdiction is almost always present. Wetland determinations are based on the presence of poorly drained, very poorly drained, alluvial, or
floodplain soils and submerged land. Watercourses are defined 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 Town or any
portion thereof not regulated pursuant to Section 22a-28 through 22a-35, inclusive, of the Connecticut
General Statutes. Intermittent watercourse shall be delineated by 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.”
500A Washington Street, Quincy, MA 02169
Wetland Summary Letter 2268 – 2284 Route 32 Montville, Connecticut 4
The Town of Montville has local regulations consisting of the Inland Wetlands and Watercourses Regulations governed by the Inland Wetlands and Watercourses Agency (IWW). Any activity that takes
place within 50 feet from the boundary of a wetland or watercourse as described within the Inland Wetlands Regulations, as referred to the “Upland Review Area” requires a permit from the IWW Agency. Portions of the property are located within 50 feet of a wetland or watercourse. Therefore, a permit from the IWW will be required for work within the 50-Foot Upland Review Area.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/
portal/nrcs/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

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.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it

was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
