Using Native Plant Communities as a Template for Green Roof Design
SUNY College of Environmental Science and Forestry Syracuse, NY
Annual Meeting of the American Ecological Engineering Society June7-9, 2012
Summary
• Native plant communities are used as the basis for a Proof-of-Concept design approach
• Rooftop growing conditions at SUNY ESF Gateway Building will emulate dune and alvar communities found along the eastern shore of Lake Ontario
• Rooftop system will meet hydrologic performance requirements, support efforts to conserve unique ecological resources, and educate ESF’s broad community, including parents, students, Board, SUNY, municipal officials, designers,…
Green Roof Design in NY
• NYS Stormwater Management Design Manual: Green Roof (Chapters 4/5)
P (in) = 90% Rainfall Event Number (See Figure 4.1) = 0.9I = Impervious Cover = 100 PercentRv = 0.95 A = site area = 9500 SF Minimum Rv = 0.2 if WQv > RRv
• Designer resistance– Innovative? Need proof of concept– Faith?
• Plant propagation– Sedums are widely available
• Cost – Additional soil, unusual plants and increased structural
loads• Management
– is it a garden, or a native system?
