The first, Udifluvents, consists of spoil material that was piled up along the Caloosahatchee River when the waterway was dredged. Udifluvent soil has very dark gray fine sand. Its surface layer is about 25 inches thick. Udifluvent's composition will vary from place to place and from layer to layer because it is not natural soil. Udifluvent soil could be useful for one cause in one location but in another location it may not be useful for the same purpose.
Udifluvent soil is a common type of soil to build homes on and other buildings.
