Central Park’s Engineer’s Gate at Fifth Avenue & 90th Street is a heavily used access area to the Park’s walkways, running paths and the Jacqueline Kennedy Onassis Reservoir. It’s also a convenient public space where cyclists, runners and visitors alike congregate to meet and relax. The Conservancy wanted to safely transplant an existing large Cherry tree and plant two major Princeton Elm trees on each side of the 90th Street entrance to Central Park.
