A subaerial soil area composed of a variety of fill materials (construction debris, dredged or pumped sediments, etc.) deposited and smoothed to provide building sites and associated uses (e.g. lawns, driveways, parking lots). These fill materials are typically 0.5 to 3 m thick and have been deposited unconformably over natural soils (Schoeneberger and Wysocki, 2005). Compare – Dredge Spoil Bank.
