National September 11 Memorial with Permaloc CleanLine
The newly opened National September 11 Memorial is located at the site of the former World Trade Center complex, and occupies approximately half of the 16-acre site. The 9/11 Memorial features two enormous waterfalls and reflecting pools, each about an acre in size, set within the footprints of the original twin towers. The Memorial Plaza is one of the most eco-friendly plazas ever constructed. More than 400 trees are planned for the plaza, surrounding the Memorial’s two massive reflecting pools. Its design conveys a spirit of hope and renewal, and creates a contemplative space separate from the usual sights and sounds of a bustling metropolis.
Swamp white oak trees create a rustling canopy of leaves over the plaza. This grove of trees bring green rebirth in the spring, provide cooling shade in the summer and show seasonal color in fall. A small clearing in the grove, known as the Memorial Glade, designates a space for gatherings and special ceremonies.
The memorial was designed by Michael Arad, a partner at Handel Architects, and Peter Walker of the landscape architecture firm Peter Walker and Partners.
Permaloc was extremely honored to be selected as the landscape edging for the site by Peter Walker and Partners. Our CleanLine aluminum landscape edging product is used throughout the site to separate various areas of the landscape and hardscapes.
