Project of the Week Mini Description & Details

Opening almost 15 years after 9/11 in June 2016, the $50 million World Trade Center’s Liberty Park is an elevated, one-acre linear park built on top of a vehicular security-screening center overlooking the original footprint of the World Trade Center, now the National September 11th Memorial. Designed for the Port Authority of New York and New Jersey by landscape architect Joseph E. Brown, the rooftop park features many trees – including a descendant of Anne Frank’s famous Horse Chestnut Tree – plus shrubs, perennials and unique seating that provides a place for visitors to reflect, relax and recharge amidst bustling New York City.

One of the park’s most striking features is the multi-hued 25 feet high and 336 feet long G-O2® Living Wall by Plant Connection that transforms the prosaic walls and garage entrances leading to the network of underground roadways and loading docks. Home to over 20,000 evergreen groundcovers and flowering perennials including Baltic Ivy, Common Periwinkle, Coral Bells, Japanese Spurge, and Wintercreeper that provide year-round visual interest of color and texture, the plantings were designed in a staggered, horizontal grid to complement the 9/11 Memorial. The broad bands of color also help soften the scale and façade of the building along Liberty Street, and an extensive 18-zone drip irrigation provides water for the living wall. The 845 stainless steel panels were pre-grown and monitored at Plant Connection’s nursery, ensuring the roots anchored into the panels and media before hanging vertically. Once home to the Deutsche Bank building, Liberty Park came after three years of intensive planning, designing, engineering, and coordinating with a multidisciplinary team of professionals. Collectively, they have transformed the site into a meaningful and memorable space where life and greenery symbolize the rebirth of Lower Manhattan – while always remembering the past.
