Remarks:
It had been fairly dry just prior to the field survey.
However, the swale appears to remain saturated for long
durations during the growing season. The floodplain
swale receives runoff from adjacent uplands during
stormwater events, and the swale in the Cape Fear River floodplain receives infrequent overflow flooding
from the Cape Fear River. It does not appear that groundwater is a major contributor to the hydrology of the wetland in this area.

The trees and shrubs were recently cleared. Approximately 60-70% of the area is denuded due to the clearing and is devoid of vegetation. American
elm, box elder, and red maple trees are near the sample plot. The smaller size of these trees along with them all being light mast producing species
(i.e. early invading pecies) probably indicates that this area had been cleared within the last 30 years.

Remarks:
This stream terrace in the Cape Fear River floodplain
receives infrequent overflow flooding from the Cape Fear River. The area is moderately well -drained.
In a soil sample near the data point, after 12 inches of
silt loam, the soil auger hit a cavity from 12-30 inches, which was probably piping from groundwater flow.
This underground drainage likely ameliorates the drainage of this upland data point rapidly.

Remarks
Soils appear to be moderately well -drained.
Approximately 30 feet to the east of the recorded data point, after 12 inches of soil the soil auger dropped 12-18 inches into a cavity. This is assumed to be
piping of groundwater through the sandy soil. Groundwater was not hit, however. This piping likely affects the hydrology and soils in the immediate area near the
sample point. In a nearby ephemeral channel, there is a deep headcut that drops approximately 8 feet into the headcut. At the base of the headcut, there is
perennial groundwater flow.

Remarks:
This is moderately well -drained high stream terrace in the Cape Fear River floodplain that may receive infrequent overflow flooding from the Cape Fear River. A
small ephemeral swale drains into the recently cleared
area, but the hydrology does not appear to be for
long durations, and no evidence of anaeobic conditions
were noted.
