The land developed for National Harbor was previously Salubria Plantation, built in 1827 by Dr. John H. Bayne. The plantation house burned down in 1981 and was offered for sale along with the surrounding land. The land was sold in 1984 and in 1994 was rezoned for mixed-use development. In the fall of 1997, the Maryland Department of the Environment and the Army Corps of Engineers approved new developer permits, granted for the PortAmerica project in 1988.
