This 8-hour urban Green Infrastructure course, presented in four 2-hour webinars, focuses on soil protection and rehabilitation; green roofs; green and living walls; filter strips; super-absorbent turf; prairie plantings; pervious paving; rain gardens; stream and shoreline stabilization; urban forests; bio-swales; rain water harvesting; and stormwater wetlands.
Also addressed are non-structural issues such as: cold climate GI; road salt; street sweeping; and capital costs.
Green Infrastructure (GI) uses vegetation and soil to manage urban stormwater. Gray Infrastructure uses only pipes and ponds to manage stormwater. Smart cities use them both, and optimize each.
Green Infrastructure goes by many names... in North America: Best Management Practices (BMP’s); Low Impact Development (LID); Conservation Design; Sustainable Site Design or Sustainable Development (associated with LEED and SITES); or Design with Nature (McHarg). If traveling to the UK, their term for GI is: Sustainable Urban Drainage System (SUDS); but, in Australia it’s: Water Sensitive Urban Design (WSUD). If you are considering a trip to China, remember their preferred term is now “Sponge Cities.” However, Green Infrastructure is the most global of all these terms.
Green Infrastructure does not replace a city's existing gray infrastructure. Instead, the two strategies work best when they complement each other for the least overall cost, with the greatest flood protection, and the cleanest surrounding lakes, rivers and beaches.
Stormwater management practices address: construction pre-treatment and post-construction. Stormwater treatment mechanisms address these practices: pretreatment; filtration; infiltration; sedimentation; and chemistry.
Instructor Peter MacDonagh, director of design + science at Kestrel Design Group, Inc., specializes in state-of-the-art ecological restoration, urban forestry, stormwater planning and green roof technologies. He has more than 30 years of experience providing ecological and sustainable site design for stormwater management, lake and river restoration, natural areas management plans, botanical inventories, urban forests, green roof installations and mining reclamation. He is a Registered Landscape Architect in 7 states and 1 Canadian Province and was inducted as a Fellow of the ASLA in 2013. He serves as Adjunct Faculty at the University of Minnesota's College of Design and continues to build his professional credentials and carry the message of alternative future scenarios by speaking across the world about green technologies in the landscape.
MacDonagh has designed and overseen installation of all the green infrastructure techniques described in this course, at many scales. These GI techniques are presented along with case studies from many parts of North America; and are supplemented with peer-reviewed research.
