Sustainable Design

The Memorial plaza has been created as one of the most sustainable, green plazas ever constructed. Its irrigation, storm water and pest management systems will conserve energy, water and other resources.

Rainwater will be collected in storage tanks below the plaza surface. A majority of the daily and monthly irrigation requirements will be met by the harvested water.

The project is pursuing the Gold certification in the U.S. Green Building Council’s LEED for New Construction program. LEED is a third party certification program for green building, design and construction. The plaza is also built to meet requirements of New York State Executive Order 111 and the WTC Sustainable Design Guidelines, which both promote environment-friendly practices.

This urban forest will flourish near adjacent green spaces, including Battery Park City, City Hall Park, Liberty Plaza, the churchyards at Liberty Church and St. Paul’s Chapel as well as the planned Liberty Park just south of the Memorial.
