These are the moderately well drained Butlertown soil, the well drained Caroline , Chillum , Matapeake , and Sassafras soils, and the poorly drained Leonardtown soils. Butlertown soils have formed in silty materials and have less than 15 percent particles coarser than very fine sand in the particle-size control section. The Sassafras, Caroline, Chillum, and Matapeake soils lack fragipans. Moderately well drained. Runoff is slow on nearly level areas and moderately rapid to rapid on the sloping areas.
Permeability is slow or very slow.
There is a perched water table above the fragipan from about November to April. Many areas are used for general crops, tobacco, and some pasture. Large areas are in residential developments. Native vegetation includes black oak, white oak, pin oak, sweetgum, red maple, and loblolly pine. The series is of large extent.
