The Riverdale Historic District was designated by the New York City Landmarks Preservation Commission on October 16, 1990. The Designation Report describes the District as notable for its landscaping features, for the architectural style of the buildings, for its history as the earliest known railroad suburb in New York City, for the way it exemplifies the American romantic suburb of the nineteenth century, and because of its prominent residents over several generations.
