Decisions on how to use the newly created land occurred over the next few years. In 1900, the United States Senate established the McMillan Commission, a body to advise the Congress and District of Columbia on ways to improve the parks, monuments, memorials, and infrastructure of the city as well as plan for urban renewal, economic growth, and expansion of the federal government. The McMillan Commission concluded that commercial land was not needed and proposed turning the reclaimed flats into parkland. The D.C. government agreed in 1905, and the United States Commission of Fine Arts (a federal advisory agency with review authority over the design and aesthetics of projects within Washington, D.C.) and the Army Corps of Engineers concurred in 1914. Most of the reclaimed mudflats were subsequently declared to be parkland and named Anacostia Water Park (now Anacostia Park) in 1919. The National Capital Park and Planning Commission (NCPPC) signed on (belatedly) to the park plan in 1928.
