A growing list of architects, landscape architects and civil engineers are incorporating Purple-Roof-compliant green roof assemblies into their projects. Purple-Roof-compliant assemblies are sold under several different brand names worldwide. A sampling of some recent projects is below.
SOME (So Others May Eat) Conway Center, Washington, DC, USA. This 4-inch (100mm) thick Purple-Roof roof was installed to meet the District of Columbia's stormwater retention requirements, which would have otherwise required an 8-inch (200mm) thick green roof.
Sky View Parc, Phase 2, Flushing, Queens, New York, NY, USA. Located in the prime location of Downtown Flushing, Sky View Parc is one of the largest mixed-use developments in New York City, offering a new and unique investment opportunity. The owner saw value in aesthetic green and made it into NYC’s second largest green roof stormwater sponge. The landscape architect delivered a smart and spectacular design, the installer delivered despite conditions that were next to impossible, and yet the outcome is beyond expectations. This is a textbook example why you need great landscape architects that can think beyond the basics, great suppliers of high quality soils and plants, and a thorough maintenance plan that protects the owner’s investment.

Philadelphia Water Department 61st Street Facility, Philadelphia, PA, USA.
