Soil Survey of Lincoln County, West Virginia
Use and Management
Uses: This map unit is generally unsuited to farming and woodland. Most areas are
used as sites for urban development. Open areas are used for lawns or a few
home gardens.
Community Development
Suitability: Suited
Management considerations:
The seasonal wetness limits excavation and trafficability and may delay
construction activities in the winter and spring.
Shallow excavations can cave in because some cutbanks are not stable.
Low strength and the potential for frost action are management concerns on sites
for local roads and streets.
Buildings can be constructed on well compacted fill material that raises the site a
sufficient distance above the water table.
Constructing roads on raised fill material and installing a drainage system help to
prevent the damage caused by wetness.
The trench walls of shallow excavations should be reinforced.
Providing suitable subgrade material helps to prevent the road damage caused by
low strength and frost action.
