The dynamite plant was shut down in 1975 and the land was subsequently purchased by the Weyerhaeuser company for $12 million. The initial plan was to use the of land to construct a lumber export plant, but the company eventually decided to further develop the town under a New Urbanism model. DuPont, Weyerhaeuser, and the state Department of Ecology began decontamination of the original explosives plant site in 1991, with a golf course being built on the former location of the plant. In recent years, DuPont has undergone a transformation with the realization of the modern planned community of "Northwest Landing". The city is expected to have a built-out population of more than 12,000.
