“The Coastal Plain, the Shenandoah Valley, and the Mesozoic basins around Culpeper,
Farmville, Danville, and Richmond are the most likely areas to have expansive or
frost-heave-susceptible soils; however, the exact distribution can only be approximated
from current soil maps, and field visits to specific areas are necessary to determine the
actual extent of these hazards.” –DMME
