Soil Series Within the Project Right-of-Way and Project Boundaries
Soil Series Description
Evesboro The Evesboro series consists of very deep excessively drained soils on uplands. They
formed in acid sandy Coastal Plain sediments. Typically these soils have a grayish
brown sand surface layer 3 inches thick and a yellowish brown sand layer from 3 to 16
inches. The subsoil between 16 to 30 inches is yellowish brown sand. The substratum
from 30 to 72 inches is loose yellowish brown sand. This soil is excessively drained.
The slowest permeability within 60 inches is moderately rapid. Available water capacity
is very high and shrink swell potential is low. This soil is not flooded and is not ponded.
The water table is deeper than 6 feet. There are no saline horizons. This component is
not a hydric soil.
Fallsington The Fallsington series consists of very deep poorly drained soils on upland flats and in
depressions. They formed in stratified Coastal Plain sediments of marine or alluvial
origin. Typically these soils have a dark gray sandy loam surface layer 10 inches thick.
The subsoil, from 10 to 40 inches is mottled gray sandy clay loam to 32 inches and
mottled light gray loamy sand to 40 inches. The substratum is stratified light gray sandy
clay loam and sand. This soil is poorly drained. The slowest permeability within 60
inches is moderately slow. Water movement in the most restrictive layer is moderately
high for the ‘Fallsington, drained’ and ‘Fallsington, undrained’ components. Available
water capacity is very high and shrink swell potential is low. This soil is not flooded and
is not ponded. The top of the seasonal high water table is at 6 inches. The soil for the
‘Fallsington, drained’ component is rarely ponded, and the top of the seasonal high
water table is at 14 inches. The soil for the ‘Fallsington, undrained’ component is
occasionally ponded, and the top of the seasonal high water table is at 5 inches. There
are no saline horizons. This component is a hydric soil.

No information available.
Fluvaquents The Fluvaquents series consists of very deep nearly level, poorly drained soils on long
narrow floodplains. Depth to a root restrictive layer is greater than 60 inches.
Permeability is moderate and available water holding capacity is low. Water movement
in the most restrictive layer is moderately high. Available water to a depth of 60 inches
is moderate. Shrink-swell potential is low. This soil is frequently flooded. It is not
ponded. The top of the seasonal high water table is at 6 inches. Organic matter content
in the surface horizon is about 4 percent. This soil meets hydric criteria.
Fort Mott The Fort Mott series consists of very deep well drained soils on uplands. They formed in
acid moderately coarse textured Coastal Plain sediments. Typically these soils have a
loamy sand surface layer about 30 inches thick. The top 8 inches is dark grayish brown
loose loamy sand and the lower part from 8 to 30 inches is yellowish brown loose loamy
sand. The subsoil from 30 to 49 inches is yellowish brown sandy loam. The substratum
from 49 to 65 inches is strong brown loose loamy sand. This component is greater than
60 inches thick. Permeability is moderate, and available water holding capacity is
medium. A water table when present is greater than 6 feet. This soil is not flooded and is
not ponded. This component is not a hydric soil.
