This morning city officials will break ground on the new Hester Street Playground in Sara D. Roosevelt Park. Parks Commissioner Adrian Benepe, Avi Schick, chairman of the Lower Manhattan Development Corp., and Council member Alan Gerson will be there for the ceremony, at 11am. A couple of years ago, the New York Times wrote about the efforts to engage the community in the nearly $5 million project. The public is invited to attend. The Playground is located on Hester Street, between Forsyth and Chrystie.
