The first call for clearing the slums of Five Points through wholesale demolition came in 1829 from merchants who maintained businesses in close proximity to the neighborhood. Slum clearance efforts (promoted in particular by Jacob Riis, author of "How the Other Half Lives", published 1890), succeeded in razing part of Mulberry Bend off Mulberry Street, one of the worst sections of the Five Points neighborhood. It was redeveloped as a park designed by noted landscape architect Calvert Vaux and named Mulberry Bend Park at its opening in 1897; it is now known as Columbus Park.
