The character of the mission is a process accompanying a system of  actors, as a design module, led and fed by Studio. 
Upstream Seine is located in strategic areas of the Grand Paris and was an  opportunity to remind the strategies of " porous city" developed by  our team during the consultation on the future of the Paris area and "the  city of XXI century Kyoto. " 
Production area for over a century , the future of the valley of the Seine will  be built with its historic features , unlike the Parisian model who has pushed  to the periphery these productive vocations. 
Territory to inhabit, it assumes all the social and functional complexity of a  metropolitan area , while retaining its unique identity . Active territory and  instead of connections , Seine Upstream will firstly find ways to reconcile  these different functions but also face risks, including flooding , while  finding a link to the river and its banks. 
These themes announce Exploring a vision and a local project that we called the  project the " green passage ". Minor Seine bed, bank to bank , is the  starting point of an investigation that extends confluence confluence (with the  Marne and the Yerres ) . 
The issue of flood risk finally scored the debate , with in-depth reflection on  the concepts of resilience and resistance and the difficulties and ambiguities  associated with their implementation. 
We propose to detail our assumptions through places : the confluence Seine-  Marne and the relationship with the Bois de Vincennes , the " island of  Choisy " area and the Carelle Athis-Mons . Each of these areas involves  different project themes : from North to South , the respiration of the river,  forming a large metropolitan area connected by bike paths , activities and  centralities the river ; recovery arm side of the Seine and the opening of the  regional park of the city of Choisy, between the gondolas and Villeneuve Triage  ; restructuring of the productive and renewal of the urban fabric along the  Seine  |
