RE: 257 Chesterfield Road
Montville, CT
Dear Mr. Cash;
I am writing to report the results of a wetland investigation conducted at the referenced site on August 3,
2022. The work was conducted according to the requirements of the CT Inland Wetlands and
Watercourses Acts. Inland Wetlands are defined as areas of poorly drained, very poorly drained,
floodplain, and alluvial soils, as delineated by a soil scientist. Watercourses are defined as bogs, swamps,
or marshes, as well as lakes, ponds, rivers, streams, etc., whether natural or man-made, permanent or
intermittent. Watercourses may be delineated by any competent professional.
The wetlands were delineated by walking across the parcel in question and examining the upper 20" of
the soil profile with a spade and auger. Those areas meeting the requirements noted above were marked
with pink plastic flagging tape numbered WL1-27. Non-wetland test holes were marked with blue
plastic flagging.
SOILS
The wetlands consist of:
3 Ridgebury, Leicester, and Whitman soils, 0 to 8 percent slopes, extremely stony
103 Rippowam fine sandy loam
Ridgebury Soils
This component occurs on upland drainageway and depression landforms. The parent material consists of
lodgement till derived from granite, schist, and gneiss. The slope ranges from 0 to 5 percent and the
runoff class is very low. The depth to a restrictive feature is 20 to 30 inches to densic material. The
drainage class is poorly drained.
Leicester Soils
This component occurs on upland drainageway and depression landforms. The parent material consists of
melt-out till derived from granite, schist, and gneiss. The slope ranges from 0 to 5 percent and the runoff
class is very low. The depth to a restrictive feature is greater than 60 inches. The drainage class is poorly
drained.
Whitman Soils
This component occurs on upland drainageway and depression landforms. The parent material consists of
lodgement till derived from gneiss, schist, and granite. The slope ranges from 0 to 2 percent and the
runoff class is very low. The depth to a restrictive feature is 12 to 20 inches to densic material. The
drainage class is very poorly drained.
Rippowam soils
This component occurs on depression and flood plain landforms. The parent material consists of
alluvium. The slope ranges from 0 to 3 percent and the runoff class is very low. The depth to a restrictive
feature is greater than 60 inches. The drainage class is poorly drained.
The non-wetland soils were not examined in detail, except as was necessary to determine the presence or
absence of wetlands.
Non-wetland Soils
46C Woodbridge fine sandy loam, 8 to 15 percent slopes, very stony
84B Paxton and Montauk fine sandy loams, 3 to 8 percent slopes
The Woodbridge soil is on drumlins on uplands, hills on uplands. Slopes are 2 to 15 percent. The parent
material consists of coarse-loamy lodgment till derived from granite and/or schist and/or gneiss. Depth to
a root restrictive layer, densic material, is 20 to 40 inches. The natural drainage class is moderately well
drained.
Sutton soils
The Paxton component is on drumlins on uplands, hills on uplands, till plains on uplands. Slopes are 3 to
8 percent. The parent material consists of coarse-loamy lodgment till derived from granite and/or schist
and/or gneiss. Depth to a root restrictive layer, densic material, is 20 to 40 inches. The natural drainage
class is well drained.
The Montauk is on drumlins on uplands, hills on uplands. Slopes are 3 to 8 percent. The parent material
consists of coarse-loamy lodgment till derived from granite and/or coarse-loamy lodgment till derived
from gneiss and/or coarse-loamy lodgment till derived from gneiss and/or coarse-loamy lodgment till
derived from granite. Depth to a root restrictive layer, densic material, is 20 to 38 inches. The natural
drainage class is well drained.
