Renovations Under Mayor Fiorello La Guardia, Robert Moses unveiled an ambitious plan to renovate the park in the late 1930s. The plan called for the Federal Post Office to be torn down, but this plan was stopped due to opposition from city officials and community groups. The Delacorte family donated the Shew Fountain.
