Plaintiff conservation organizations bring this action to protect our Nation’s waters and the endangered species that rely on them. During the Trump Administration, Florida worked hand in glove with developers to achieve developers’ “holy grail”: state assumption over Section 404 of the Clean Water Act — which governs dredging and filling of many sensitive wetlands — in one of the most biodiverse states in the country. Between 2017 and 2020, the State and the U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, and the U.S. Army Corps of Engineers, worked to make this dream a reality. The Defendants’ actions, however, violated multiple federal laws and must be set aside.
