In February 1860, a group of fifteen commissioners submitted suggestions for locations of four large parks and three small parks in Brooklyn, as well as a series of boulevards to connect said parks. The largest of these proposed parks was a plot centered on Mount Prospect and bounded by Warren Street to the north; Vanderbilt, Ninth, and Tenth Avenues to the west; Third and Ninth Streets to the south; and Washington Avenue to the east. Egbert Viele began drawing plans for "Mount Prospect Park", as the space was initially called, and published his proposal in 1861. The park was to straddle Flatbush Avenue and include Prospect Hill, as well as the land now occupied by the Brooklyn Public Library, Brooklyn Botanic Garden, and Brooklyn Museum.
