Soil Series Within the Project Right-of-Way and Project Boundaries
Soil Series Description
Ochlockonee The Ochlocknee series consists of very deep well drained soils on flood plains.
Typically, the surface layer is brown sandy loam about 6 inches thick. The substratum is
a brown fine sandy loam layer about 31 inches thick. This in turn is over a dark brown
very fine sandy loam layer about 7 inches thick which is over dark yellowish brown
loamy fine sand about 18 inches thick. Depth to a root restrictive layer is greater than 60
inches. 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
rarely flooded. It is not ponded. A seasonal zone of water saturation is at 48 inches
during January, February, March, April, and December. This soil does not meet hydric
criteria.
Othello The Othello series consists of very deep poorly drained soils on uplands. They formed in
silty material underlain by coarser sediment. Typically, these soils have a dark grayishbrown
silt loam surface, 9 inches thick. The subsoil between 9 and 18 inches is light
olive gray silty clay loam with prominent yellowish-brown mottles and between 18 and
29 inches is light gray, silty clay loam with prominent yellowish-brown mottles. A
mottled gray sandy loam substrata grades into a light gray loamy sand below 29 inches.
Depth to a root restrictive layer is greater than 60 inches. 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 not flooded. It is not ponded. A seasonal zone
of water saturation is at 6 inches during January, February, March, April, and May.
Organic matter content in the surface horizon is about 2 percent. This soil meets hydric
criteria.
Piccowaxen The Piccowaxen component is found on terraces, fluviomarine terraces. The parent
material consists of silty and loamy fluviomarine deposits. Depth to a root restrictive
layer is greater than 60 inches. The natural drainage class is somewhat poorly drained.
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
rarely ponded. A seasonal zone of water saturation is at 12 inches during February.
Organic matter content in the surface horizon is about 4 percent. This soil does not meet
hydric criteria.
Pone The Pone series consists of very deep, very poorly drained soils formed in organic
deposits overlying alluvial or marine sediments of the Atlantic Coastal Plain. They are
found on low-lying uplands and closed depressions. Typically the surface layer is black
mucky loam 14 inches thick. The subsoil from 14 to 37 is grayish brown sandy loam
and light gray loamy sand. The substratum from 37 to 47 is gray sand. From 47 to 69
inches it is gray silt loam. Depth to a root restrictive layer is greater than 60 inches. The
natural drainage class is very poorly drained. Water movement in the most restrictive
layer is high. Available water to a depth of 60 inches is moderate. Shrink-swell potential
is low. This soil is not flooded. It is not ponded. A seasonal zone of water saturation is at
0 inches during January, February, March, April, May, June, and December. Organic
matter content in the surface horizon is about 9 percent. This soil meets hydric criteria.
