This nearly level, very poorly drained soil is in depressions and small drainageways of glacial till uplands and outwash plains. Most areas are oval and range from 2 to 20 acres. Slopes are dominantly less than 2 percent.
Typically the surface layer is black muck 20 inches thick. The substratum extends to a depth of 60 inches or more. It is gray fine sand to a depth of 22 inches and grayish brown gravelly sand at a depth of more than 22 inches.
Included with this soil in mapping are small areas of poorly drained Ridgebury and Raypol soils and very poorly drained Carlisle, Scarboro, and Whitman soils. Also included are areas in Newport County that are underlain by loamy material. Included areas make up about 10 percent of this map unit.
The permeability of this soil is rapid. Available water capacity is high. Runoff is very slow, and water is ponded on some areas. A few areas adjacent to streams are subject to flooding. The surface layer is strongly acid through slightly acid. This soil has a high water table at or near the surface most of the year.
Most areas of this soil are in woodland or have a marsh grass and sedge plant cover.
The high water table, ponding, and the low strength of the surface layer make this soil unsuitable for community development. If the soil is drained, the organic material in the surface layer shrinks and subsides, lowering the soil surface. Slopes of excavated areas are unstable.
This soil is not suited to cultivated crops. It is limited mainly by wetness, and many areas do not have suitable drainage outlets.
This soil is suited to wetland wildlife habitat, but wet ness makes the soil poorly suited to woodland wildlife habitat or open-land wildlife habitat. Capability subclass is VIw, woodland group is 5w.
This nearly level, well drained soil is on terraces and outwash plains. Areas are irregular in shape and mostly range from 3 to 200 acres.
Typically the surface layer is dark brown fine sandy loam about 7 inches thick. The subsoil is yellowish brown, reddish yellow and light yellowish brown fine sandy loam 25 inches thick. The substratum extends to a depth of 60 inches or more. It is pale brown sand to a depth of 31 inches and gravelly sand at a depth of more than 31 inches.
Included with this soil in mapping are small areas of excessively drained Hinckley soils, somewhat excessively drained Merrimac soils, well drained Enfield soils, and moderately well drained Ninigret and Sudbury soils. Also included are small areas of soils that have slopes of more than 3 percent. Included areas make up about 10 percent of this map unit.
The permeability of this soil is moderately rapid in the surface layer and upper part of the subsoil, moderately rapid or rapid in the lower part of the subsoil, and rapid in the substratum. Available water capacity is moderate, and runoff is slow. This soil is very strongly acid through slightly acid.
This soil is suited to community development. Onsite septic systems need careful design and installation to prevent pollution of ground water. Slopes of excavated areas are commonly unstable.
This soil is suited to cultivated crops, and most of the areas are used for farming. The use of cover crops and return of crop residue to the soil help to maintain organic matter content and tilth.
This soil is suitable for trees, woodland wildlife habitat, and openland wildlife habitat. It is too dry to provide wetland wildlife habitat. Capability class I; woodland group 40.
This complex consists of gently sloping to moderately sloping, well drained soils intermingled with areas of bare, hard exposed bedrock. The complex is on side slopes and crests of upland hills and ridges. Stones and boulders cover 10 to 35 percent of the surface. Areas are irregular in shape and mostly range from 5 to 40 acres. The complex is approximately 40 percent Canton soils, 20 percent Charlton soils, 20 percent rock outcrops, and 20 percent other soils. The soils and out crops are so intermingled that it was not practical to map them separately.
Typically the Canton soils have a surface layer of very dark grayish brown fine sandy loam about 3 inches thick. The subsoil is dark yellowish brown, yellowish-brown, and light olive brown fine sandy loam 19 inches thick. The substratum is olive gray and light olive gray gravelly loamy sand to a depth of 60 inches or more.
Typically the Charlton soils have a surface layer of very dark brown fine sandy loam about 2 inches thick. The subsoil is 25 inches thick. The upper 15 inches is dark yellowish brown fine sandy loam, and the lower 10 inches is yellowish brown gravelly sandy loam. The sub stratum is light brownish gray gravelly sandy loam to a depth of 60 inches or more.
Included with these soils in mapping are small areas of somewhat excessively drained Gloucester soils, well drained Paxton and Narragansett soils, and moderately well drained Sutton soils. Also included are small areas of soils that have slopes of more than 15 percent and small areas of soils with bedrock at a depth of less than 40 inches.
The permeability of the Canton soils is moderately rapid in the surface layer and subsoil and rapid in the substratum. Available water capacity is moderate, and runoff is medium. This soil is extremely acid through strongly acid.
The permeability of the Charlton soils is moderate to moderately rapid. Available water capacity is moderate, and runoff is medium. This soil is very strongly acid through medium acid.
This complex is suitable for community development but is limited by the stony surface and rock outcrops. Onsite sewage disposal systems need careful design and installation to prevent effluent from seeping to the surface, and rock outcrops make excavation difficult. Removal of stones and boulders is necessary for landscaping. The use of straw bale sediment barriers, siltation basins, and mulch and quickly establishing plant cover help to control erosion during construction.
Most areas of these soils are in woodland. The complex is suited to trees, but stoniness and rock outcrops hinder the use of equipment.
The stony surface and rock outcrops make this complex unsuitable for cultivated crops and the use of farming equipment impractical.
This complex is suitable for woodland wildlife habitat. Stoniness and rock outcrops limit the suitability for open- land wildlife habitat. The soils are too dry to provide wetland wildlife habitat. Capability subclass VIIs; wood land group 4x.
These gently sloping, well drained soils are on the crests and side slopes of glacial upland hills and ridges. Areas are irregular in shape and mostly range from 5 to 50 acres. The mapped acreage of this unit is approximately 60 percent Canton soils, 30 percent Charlton soils, and 10 percent other soils. The areas of this unit consist of either Canton soils or Charlton soils or both. The soils were mapped together because they have no major differences in use and management.
Typically the Canton soils have a surface layer of very dark grayish brown fine sandy loam about 3 inches thick.
The subsoil is dark yellowish brown, yellowish-brown, and light olive brown fine sandy loam 19 inches thick. The substratum is olive gray and light olive gray gravelly loamy sand to a depth of 60 inches or more.
Typically the Charlton soils have a surface layer of very dark brown fine sandy loam about 2 inches thick. The subsoil is 25 inches thick. The upper 15 inches is dark yellowish brown fine sandy loam, and the lower 10 inches is yellowish brown gravelly sandy loam. The sub stratum is light brownish gray gravelly sandy loam to a depth of 60 inches or more.
Included with these soils in mapping are small areas of somewhat excessively drained Gloucester soils, well drained Paxton and Narragansett soils, and moderately well drained Sutton soils. Also included are small areas of soils that have slopes of more than 8 percent.
The permeability of the Canton soils is moderately rapid in the surface layer and subsoil and rapid in the substratum. Available water capacity is moderate, and runoff is medium. This soil is very strongly acid through strongly acid.
The permeability of the Charlton soils is moderate to moderately rapid. Available water capacity is moderate, and runoff is medium. This soil is extremely acid through medium acid.
Most areas of these soils are cleared and used for farming. A small acreage is cleared and used for pasture.
These soils are suitable for community development. The use of siltation basins, straw bale sediment barriers, and mulch and quickly establishing plant cover help to control erosion during construction.
These soils are suited to cultivated crops. The hazard of erosion is moderate. Strip-cropping, the use of cover crops, and the return of crop residue to the soil help to control erosion and maintain tilth and organic matter content.
These soils are suitable for trees, woodland wildlife habitat, and openland wildlife habitat. The soils are too dry to provide wetland wildlife habitat. Capability sub class IIe; Canton part in woodland group 5o, Charlton part in woodland group 4o.
This nearly
level, very poorly drained soil is in depressions of outwash plains and glacial
upland till plains. Areas are irregular in shape and mostly range from 5 to 100
acres. Slopes are less than 2 percent.
Typically this soil has a surface layer of black and dark reddish brown muck 55
inches thick. The substratum is gray loamy sand to a depth of 60 inches or more.
Included with this soil in mapping are small areas of poorly drained Walpole and
Leicester soils and very poorly drained Adrian, Scarboro, and Whitman soils.
Included areas make up about 10 percent of this unit.
The permeability of this soil is moderately slow through moderately rapid.
Available water capacity is high, and runoff is very slow. The soil has a
seasonal high water table at or near the surface during most of the year. The
soil is subject to ponding, and a few areas adjacent to streams are frequently
flooded. This soil is medium acid through neutral.
This soil is poorly suited for community development. The high water table and
the low strength of the surface layer are the main limitations. The use of
onsite septic systems is not feasible in this soil. When the soil is drained,
the surface layer shrinks and subsides.
This soil is poorly suited to trees, but it is better suited to woodland than to
most other uses, and most of the areas are wooded or in grassy bogs. The high
water table restricts the root depth of trees, and they are subject to being
blown over by strong winds. Seedlings are difficult to establish.
Wetness makes this soil poorly suited to cultivated crops. Suitable drainage
outlets are not available in most places. If this soil is drained, care is
needed to prevent excessive subsidence of the surface layer.
This soil is suitable for wetland wildlife habitat, but wetness makes the soil
poorly suited to woodland wild life habitat or openland wildlife habitat.
Capability sub class VIw; woodland group 4w.
This gently
sloping, somewhat excessively drained soil is on undulating terraces and outwash
plains. Areas are irregular in shape and mostly range from 2 to 75 acres.
Typically the surface layer is dark brown sandy loam about 8 inches thick. The
subsoil is yellowish brown and dark yellowish brown sandy loam 17 inches thick.
The substratum is light yellowish brown gravelly sand to a depth of 60 inches or
more.
Included with this soil in mapping are small areas of excessively drained
Windsor and Hinckley soils, well drained Agawam soils, and moderately well
drained Ninigret and Sudbury soils. Also included are small areas of soils that
have slopes of less than 3 percent and areas of darker colored soils. Included
areas make up about 10 percent of this map unit.
The permeability of this soil is moderately rapid in the surface layer and upper
part of the subsoil, moderately rapid to rapid in the lower part of the subsoil,
and rapid in the substratum. Available water capacity is moderate, and runoff is
medium. The soil is extremely acid through medium acid.
This soil is suitable for community development. Onsite septic systems need
careful design and installation to prevent pollution of ground water. Slopes of
excavated areas are commonly unstable. Lawn grasses, shallow- rooted trees, and
shrubs require watering in the summer. The use of straw bale sediment barriers,
quickly establishing plant cover, and providing temporary siltation basins help
to control erosion during construction.
This soil is suited to trees, but droughtiness causes seedling mortality in the
summer.
This soil is suited to cultivated crops. Irrigation is needed, and the hazard of
erosion is moderate. Strip- cropping, cover crops, and the return of crop
residue to the soil help to control erosion and maintain tilth and organic
matter content.
This soil is suited to woodland wildlife habitat and openland wildlife habitat.
It is too dry to provide wetland wildlife habitat. Capability subclass IIs;
woodland group 4s.
This nearly
level, poorly drained soil is in depressions and drainageways of glacial upland
hills and drumlins. Slopes range from 0 to 3 percent but are dominantly less
than 2 percent. Areas are long and narrow and range mostly from 5 to 75 acres.
Also included are small areas of soils that have stones on the surface. Included
areas make up about 10 percent of this map unit.
The permeability of this soil is moderate or moderately rapid in the surface
layer and subsoil and slow or very slow in the substratum. Available water
capacity is moderate, and runoff is slow to medium. This soil has a seasonal
high water table at or near the surface from late fall through spring. The soil
is very strongly acid through medium acid.
Most areas of this soil are wooded or are cleared and used for crops and
pasture.
The slow or very slow permeability in the substratum and the seasonal high water
table make this soil poorly suited to community development. Onsite septic
systems require special design and installation, and areas need extensive
filling. Subsurface drains are needed to help prevent wet basements. Quickly
establishing plant cover and the use of siltation basins and temporary
diversions help to control erosion during construction.
This soil is suited to trees. The main limitation for woodland is wetness; tree
windthrow is common, and the use of equipment is limited during wet seasons.
This soil is suitable for farming, but artificial drainage is needed. The use of
cover crops and the return of crop residue to the soil help to maintain tilth
and organic matter content. The soil is suited to most types of wildlife
habitat. Capability subclass IIIw; woodland group 4w.
This complex
consists of moderately well drained to excessively drained soils that have been
disturbed by cuffing or filling, and areas that are covered by buildings and
pavement. The areas are mostly larger than 5 acres. The complex is about 70
percent Udorthents, 20 percent Urban land, and 10 percent other soils. Most
areas of these components are so intermingled that is was not practical to map
them separately.
Udorthents are in areas that have been cut to a depth of 2 feet or more or are
on areas with more than 2 feet of fill. Udorthents consist primarily of
moderately coarse textured soil material and a few small areas of medium
textured material.
Included with this complex in mapping are areas, up to 10 acres in size, of
undisturbed soils. Also included are a few areas that are entirely Udorthents.
Most cut areas were used as a source of fill material, but in some areas cuts
were made in order to level sites for buildings, recreational facilities, and
roads. Most of the filled areas were built up and leveled for urban development.
In some areas fill has been used to build up recreational areas and highways.
The permeability and stability of this unit are variable. The unit requires
onsite investigation and evaluation for most uses. Capability subclass and
woodland group not assigned.
