Soil Series Within the Project Right-of-Way and Project Boundaries
Soil Series Description
Beltsville The Beltsville series consists of deep moderately well-drained soils on uplands. They
formed in Coastal Plain sediments. Typically, these soils have grayish-brown and light
olive brown silt loam surface layers to a depth of 9 inches. The subsoil from 9 to 25
inches is yellowish-brown silt loam and silty clay loam. From 25 to 50 inches is a very
firm and brittle silty clay loam fragipan. The substratum from 50 to 72 inches is very
pale brown gravelly sandy loam. The parent material consists of silty eolian deposits
over loamy fluviomarine deposits. Depth to a root restrictive layer, fragipan, is 20 to 40
inches. The natural drainage class is moderately well drained. Water movement in the
most restrictive layer is moderately low. Available water to a depth of 60 inches is low.
Shrink-swell potential is low. This soil is not flooded. It is not ponded. A seasonal zone
of water saturation is at 24 inches during January, February, March, April, and
December. Organic matter content in the surface horizon is about 3 percent. This soil
does not meet hydric criteria.
Berryland The Berryland series consists of deep very poorly drained soils on uplands. They formed
in Coastal Plain sediments. Typically these soils have a black sand surface layer 10
inches thick over 2 inches of gray sand. The subsoil from 12 to 20 inches is firm and
weakly cemented dark reddish brown loamy sand. From 20 to 30 inches the subsoil is
dark gray loose sand. The substratum from 30 to 72 inches is grayish brown stratified
loose sand. This soil is very poorly drained. The slowest permeability within 60 inches
is moderately rapid to rapid. Available water capacity is very high and shrink swell
potential is low. This soil is rarely flooded and is not ponded. The top of the seasonal
high water table is at 0 inches. There are no saline horizons. This component is a hydric
soil. Berryland, drained – The soil is not flooded and is rarely ponded. The top of the
seasonal high water table is at 5 inches. Berryland, undrained – The soil is not flooded
and is frequently ponded. The top of the seasonal high water table is at 2 inches.
Butlertown The Butlertown series consists of deep well drained to moderately well drained soils on
uplands. They formed in Coastal Plain sediments. Typically these soils have a dark
grayish brown silt loam surface layer 10 inches thick. The subsoil from 10 to 34 inches
is light yellowish brown and yellowish brown silt loam. A firm and brittle fragipan from
34 to 49 inches is mottled yellowish brown silt loam. The substratum from 49 to 60
inches is mottled yellowish brown silt loam. Depth to a root restrictive layer is greater
than 60 inches. Water movement in the most restrictive layer is moderately low.
Available water to a depth of 60 inches is high. Shrink-swell potential is low. This soil is
not flooded. It is not ponded. A seasonal zone of water saturation is at 36 inches during
February and March. Organic matter content in the surface horizon is about 2 percent.
This soil does not meet hydric criteria.
Cedartown The Cedartown series consists of very deep somewhat excessively drained soils on
uplands of the Mid-Atlantic Coastal Plain. They formed in sandy alluvial and marine
sediments. Typically, these soils have a dark brown loamy sand surface from 0 to 6
inches. The subsurface from 6 to 14 inches is light yellowish brown sand. The subsoil
from 14 to 30 inches is strong brown loamy sand. The substratum from 30 to 42 inches
is strong brown loamy sand, brownish yellow sand from 42 to 54 inches, mottled
yellowish brown sand from 54 to 64 inches, and mottled gray fine sandy loam from 64
to 72 inches. This soil is somewhat excessively drained. This soil is not flooded and is
not ponded. The top of the seasonal high water table is at 45 to 57 inches. There are no
saline horizons. This component is not a hydric soil.
