1) From Olmsted´s legacy to Singapore´s ABC Water Guidelines. How dense cities can do better in integrating blue-green infrastructure
Citizens need access to nature! Since at least the concept of Biophilia found its way not only into universities but also municipalities, nature based solutions are getting more accepted. Yet appreciating blue-green features as mandatory ingredient of dense cities has many ancestors. One of them was Frederick Law Olmsted, known for Boston´s Emerald Necklace. But he too struggled to convince urban decision makers of this necessity. If his “Vision Plan” for Los Angeles were realized in the 1930ies, today the entire city would do better in terms of accessible nature and balanced microclimate for all residents. Our recent research project with Harvard GSD, MIT, National University of Singapore and Zeppelin University focused on (1) understanding the enabling conditions, drivers of change as well as anti blue-green infrastructure (BGI) agents, and (2) developing proper argumentation for BGI. In a staged interdisciplinary dialogue between a journalist, Ramboll LCL and a municipality the main results of this research will be discussed. The session will focus on the changing nature of professional collaborations, structural and cultural capacity required as baseline for success, as well as successful participatory planning practices; particular emphasis will be placed on ways of innovative financing and forms of capital. The session will be richly illustrated with case studies from Portland´s Tanner Spring Park to Berlin´s Potsdamer Platz and one of the most award winning blue-green projects in Singapore. European and Asian examples will be examined from the point of view of transferability to North-Eastern US. Michael KIMMELMAN, Architecture critic for The New York Times was asked to moderate the session. Representative from a municipality has to be decided

2) The Evolution of Green Infrastructure and Stormwater Management
Green Infrastructure (GI) has come to the forefront of stormwater management for cities across the country. Over the past decade, regulatory agencies have increased support for GI and it is now a requirement in stormwater permits and CSO consent decrees. In fact, these requirements are tied to strict deadlines and performance metrics that pose new challenges. This study presents the evolution of GI and provides examples of how cities are adapting to change and overcoming these challenges.
Challenges start in the planning phase where regulatory constraints often do not allow adequate time for screening and goal-setting, forcing municipalities into requirements that may not be achievable. Early coordination with other agencies and the private sector is also critical for establishing long-term agreements as well as grant and redevelopment programs. Long-term success of GI relies on proper maintenance. The paradigm shift from grey to green has left cities scrambling to figure out how to properly staff and budget for large-scale implementation. Stormwater management practices are now more dispersed and require new thinking in asset management and how to effectively monitor long-term performance on a large scale. Large-scale GI programs like NYC, Philadelphia, and Washington DC all have unique challenges to overcome that were specific to their programs. Understanding their approaches will help others gain perspective to adapt and overcome their own challenges.
