Altavista soils have mottles with chroma of 2 or less in the upper 24 inches of the argillic horizon and have base saturation of less than 35 percent. Cahaba and Kempsville soils have siliceous mineralogy and base saturation of less than 35 percent. Capshaw soils have more than 35 percent clay in the particle-size control section. Masada soils have base saturation of less than 35 percent, and contain more than 35 percent clay in the particle-size control section. State and Wickham soils have less than 35 percent base saturation.
Pamunkey soils are on nearly level to sloping stream terracess.
Slopes are commonly 2 to 7 percent, but range from 0 to 15 percent. These soils have formed in stratified fluvial sediments derived principally from weathered igneous and metamorphic rocks. Chewacla, Congaree, Riverview, and Wehadkee soils are on floodplains. Fork and Chewacla soils are somewhat poorly drained. Hiwassee and Turbeville soils have more than 35 percent clay in the particle-size control section.
