park. Tension and conflicts began to develop between the bohemian element and the remaining working-class residents of the neighborhood. The city government began showing an increasing hostility to the use of public facilities by the public and, in 1947, began requiring permits before public performances could be given in any city park. In the spring of 1961, the new parks commissioner refused a permit to the folksingers for their Sunday afternoon gatherings, because "the folksingers have been bringing too many undesirable [beatnik] elements into the park." On April 9, 1961, folk music pioneer Izzy Young, owner of the Folklore Center—who had been trying to get permits for the folksingers—and about 500 musicians and supporters gathered in the park and sang songs without a permit, then held a procession from the park through the arch at Fifth Avenue, and marched to the Judson Memorial Church on the other side of the park. At about the time the musicians and friends reached the church, the New York City Police Department Riot Squad was sent into the park, attacked civilians with billy clubs, and arrested 10 people. The incident made the front pages of newspapers as far away as Washington, DC. The New York Mirror initially reported it as a "Beatnik Riot", but retracted the headline in the next edition, although tensions remained for a while.

Changes to the park included moving the fountain off center to improve its visual alignment with the arch when viewed from above, replacing the perimeter fence with a taller fence, and flattening and shrinking the central plaza, the park's politically contested gathering space. The plan also called for felling dozens of mature trees and installing ornamental water plumes in the fountain. A spectrum of opponents had charged the mayor variously with privatizing the park and with social engineering park use, as part of a broader web of speculation schemes threatening nearby South Village and East Village communities and architecture. Five lawsuits were filed to challenge NYC Parks' renovation plans. In July 2006, New York County Supreme Court Justice Emily Jane Goodman enjoined any renovation work on the fountain or fountain plaza area, pending further review of the plans by the local community board, the New York City
