Fleming and later by his widow, and eventually demolished in 1927 to be replaced on the same site by the neo-Georgian mansion that still stands at 3536 Newark Street NW.[8] Early large-scale development was spurred by the neighborhood's upland topography, which provided a breezy relief from the hot, fetid air in the lowlands that were then the built-up area of Washington, D.C.Development proceeded in fits and starts, punctuated by such events as the bankruptcy of the Cleveland Park Company in 1905[6]: 9 and the Great Depression in the 1930s.The Cleveland Park Club was founded in 1922 to "promote social intercourse, recreation and sports, literature and the arts, and for mutual improvement" of the neighborhood in the days before television and widespread broadcasting and movies.
