This environmentally sensitive site in Van Cortland Park exemplifies the contemporary trend of multi-use infrastructure with an emphasis on public use and sustainability with a program implementing a new golf driving range, stormwater management, and security. The design provides habitat, park restoration, visual enhancement, facilities and, above all, site security for a multi-billion dollar public works facility. Located in an environmentally sensitive site of historic Van Cortland Park, the project includes riparian woodlands and wet meadows that are to be protected. The landscape program incorporates a sustainable 9-acre green roof within an 11-acre driving range, which is located over the subterranean water filtration plant. It is also driven by security requirements while creating a natural terrain at the driving range. The result is a landscape earthwork where there is nearly two miles of site walls that constitutes a moat surrounding the site and plant. This moat is also the wetland treatment cells of the stormwater treatment system. Principal goals for the project were: 1. To minimize the discharge of site water into New York City’s combined sewer through storm water and ground water detention on site beyond that of required city regulations. 2. To minimize the use of potable water on site through the reuse of retained storm and ground water. 3. To create native ecological habitat on site.
