World Trade Center (WTC) Liberty Park Living Wall

Opening almost 15 years after 9/11 on June 29, 2016, the $50 million World Trade Center’s Liberty Park is an elevated, one-acre linear park (inspired by the nearby iconic High Line) 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 park features many trees, shrubs, perennials and unique seating that provides a place for visitors to reflect, relax and recharge amidst the bustling city.

Designed by Santiago Calatrava, the future St. Nicholas Greek Orthodox National Shrine surrounds Liberty Park and is a modern evolution of the Byzantine style church with a dome, still under construction. Liberty Park has a capacity of 750 people and is open to the public from 6 a.m. to 11 p.m. every day. “Liberty Park also serves as a green roof and demonstrates several other sustainable features including LED lighting plus guardrails and benches fashioned from reclaimed teakwood,” (Port Authority of New York and New Jersey).

One of the park’s most striking features is the multi-hued 25 feet high and 336 feet long G-O2(R) Living Wall by Plant Connection that transforms the prosaic walls and garage entrances leading to the network of underground roadways and loading docks. The living wall 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 facade of the building along Liberty Street.

This notable accomplishment comes after three years of intensive planning, designing, engineering, and coordinating with a multidisciplinary team of architects, landscape architects, designers, horticulturists, engineers, and contractors. Collectively, they have transformed the site that was once the Deutsche Bank building into a meaningful and memorable space where life and greenery symbolize the rebirth of Lower Manhattan – while always remembering the past.

The Port Authority of New York and New Jersey, 2016, see below, says: “Creative vertical gardening is transforming what otherwise would be the prosaic walls of the Vehicle Security Center into green space for New Yorkers and visitors to the World Trade Center,” said Pat Foye, Executive Director of the Port Authority.

And “The Living Wall provides a green space that symbolizes the resiliency of New Yorkers, the vibrancy of Lower Manhattan and its connection to the Memorial Plaza,” said Steve Plate, Port Authority Chief of Major Capital Projects.

The living wall is home to over 20,000 evergreen groundcovers and flowering perennials (Baltic Ivy, Common Periwinkle, Coral Bells, Japanese Spurge, and Wintercreeper) that provide year-round visual interest of color and texture, while thriving vertically in the partially shaded environment. The plants are housed in 845 stainless steel patented G-O2(R) Living Wall panels. An extensive 18-zone drip irrigation provides water for the living wall, while a built-in monitoring system ensures the living wall’s health. Custom stainless steel catch basins hang under the living wall panels to capture any residual water.

The Liberty Park G-O2(R) Living Wall, like all of Plant Connection’s G-O2(R) Living Walls, was pre-grown before it was installed, ensuring that the roots anchored into the panels and media before hanging vertically. Beginning in 2015, the planted panels were grown at Plant Connection’s nursery in Riverhead, NY, where they were monitored and maintained by horticulturists in an optimum greenhouse growing environment.

One retired 9/11 NYPD officer expressed their feelings after seeing the living wall coverage: “Thank you, Melissa, for your hard work, on behalf of our fallen brothers and sisters. It is nice to see that people haven’t forgotten. I would love to see this before I pass. Unfortunately, the pain is still too great to go there. You are bringing such beauty to this solemn place. Again, thank you. Your work is very much appreciated.”

The Liberty Park G-O2(R) Living Wall offers a touch of earth amid a concrete jungle – and what better place to provide a piece of serenity and enhance the environment. The G-O2(R) Living Wall at Liberty Park pushes aside boundaries and invites people to come together from all walks of life to simply breathe fresh air and enjoy the newfound beauty.

“In addition to the wall, the park also features the Horse Soldier statue in honor of the troops who served in Afghanistan during Operation Enduring Freedom; a descendant of Anne Frank’s famous Horse Chestnut Tree, and more than 150 trees and shrubs. Construction of the Greek Orthodox Church continues on the park and will serve as both a church and bereavement center. The southwest corner of the park will feature the Liberty Street pedestrian bridge that crosses over West Street to Brookfield Place in Battery Park City,” (The Port Authority of New York and New Jersey, 2016).

Video & Project of the Week for August 25, 2014: Nathan Phillips Square Toronto City Hall Podium Green Roof

Toronto City Hall Podium Green Roof

Project Description & Details

The multi-award winning Nathan Phillips Square (NPS) is Toronto’s premier public space and civic gathering place, a leading tourist attraction for the city, and a national and provincial landmark. The design competition to revitalize NPS was won by the design team of PLANT Architect, Perkins+Will Shore Tilbe Architects and Hoerr Schaudt Landscape Architecture in part based on providing a publicly accessible green roof on the podium roof. The new 2.7-acre upper-level urban plaza garden is now a vibrant, active space and Canada’s largest accessible living roof.

From the start the Nathan Phillips Square Toronto City Hall Podium Green Roof was designed to be grown and installed in a modular system. Grown at the LiveRoof Ontario nursery, it employs a combination of 6″ deep LiveRoof® Deep System Modules and 4″ deep LiveRoof® Standard Modules. Twenty-two different plant blends include grasses, sedums and perennials in a kaleidoscope of colors. The design consists of three formal conditions: a sedum mosaic, a paved courtyard that frames the curved chamber and a deck cafe that occupies the prow. The perimeter garden is treated as a field in purple, pink, yellow/orange and green sedums. Installed by general contractor Flynn Canada Ltd., new landscaped gardens, courtyards, terraces, furniture and walkways provide unique views of downtown from this urban oasis in the heart of the city. Every year, over 1.5 million visitors attend a variety of community and special events hosted here.

Project of the Week for March 3, 2014: Virginia Commonwealth University (VCU) Pollak Building

Greenroofs.com Project of the Week: 3/3/14

Virginia Commonwealth University (VCU) Pollak Building
Richmond, VA, USA

4,020 sq. ft Greenroof

VCUPollak1

Project Description & Details

Designed by VMDO Architects with Siteworks Studio, the walkout terrace located on the 5th floor of the Pollak Building Visual Arts Building at Virginia Commonwealth University (VCU) serves as a living classroom and provides for an opportunity for the students and faculty to congregate outside. The roof illustrates three different types of green roof planting strategies and depths with conventional (3-4”), meadow (6”), and plants native (12”) to Virginia – the first such green roof in the Commonwealth.

Installed by Capitol Greenroofs with greenroof consulting by Roofmeadow, the assembly utilizes a Carlisle Garden Roof with Optigreen drainage and growing media, provided by Conservation Technology, over an IRMA roof.  Students from the VCU School of the Arts Department of Interior Design spent a day planting the perennials, grasses and succulents. Corten steel planters were placed randomly in the planting areas. Galvanized grating leads to a new handicap accessible entrance and a 1,500 sf Pennsylvania bluestone patio flanks either side of the grating. VCU installed a 16 foot tall Eddy GT, 1 kW vertical axis wind turbine on the top of the southeast stair tower on the Pollak Building in the spring of 2012 which can be seen from the greenroof.
