Abstract
Transactions between the city and flood : towards a resilient urban design Urban development projects in flood-prone area are presented as configurations-both spatial and actorial-during which transactions between the city and the flood risk are implemented in order to integrate the latter and to achieve a resilient urban design. The cross-cutting study of four urban development projects developed in flood prone built areas in France-the Rives de Maine district in Angers, the Berges de la Robine district in Narbonne, the Eure St-Nicolas district in Le Havre and the Matra district in Romorantin-highlights the broad categories of transactions necessary for a resilient urban design. We first identify three different kinds of generic spaces allowing transactions between the city and flood : raised spaces, hydraulic transparencies, landscape design of the city/water interface. We then show that the taking into account of flooding in an urban development project is related to the ability of stakeholders to articulate the technical and sensitive registers, as well as a regulatory logic and a project logic. The aim is to make possible the confrontation of the stakeholders and the invention of solutions to organize space which are the result of inventive negotiations.
