Polycentrality within the Greater Paris, a polysemic figure

Abstract : As the nature of metropolitan space generates correlated process of prosperity/poverty, intensification/depression, concentration/dispersion, the process of planning and designing it requires new approaches. One of the rising paradigms we wish to explore in this paper is the issue of the polycentrality and the way of understanding and planning it within the metropolis. Certainly, it covers the image of a territorial structure around several poles ; but it also evokes the diversity of poles – either poles of various nature or poles of different scales -, their influence and their interrelations. Through its various models and spatialities, figures of polycentrality need to be understood according to a polysemic view, depending on their meanings and functions within their socio-historical contexts. The recent experience of the Greater Paris project as a pivotal moment will help us for the investigation of this notion, its heritage, its mutations and its contemporary significations. The idea of the Greater Paris is not new. Since the Paris annexation by Eugène Haussmann achieved in 1860, it has produced many representations that superimposed while building progressively a metropolitan imaginary. Issues raised from the last five years of intensive work led through Greater Paris project - since the launching of the international urban consultation on the future of Greater Paris -, need first to be enlightened by the metropolitan heritage, in particular the radioconcentric structure which marked the development of the relations between Paris and its regional environment. Despite its progressive erasing, this figure still influences the debate on the metropolitan future and its historicity played a key role in the consultation. However, urban configurations raised from the consultation have developed contrasted meanings for polycentrality. The debate around the proposals has raised controversies, all the more chronic that they crystallized further through the metropolitan projects which have been engaged since. We will focus on two of them, being currently on process. First one is the Grand Paris Express project, a supermetro designed at a regional scale. Second one is the Saclay campus-cluster in the south-west part of the region. The paper will analyze various views issued on the topic of urban polycentrality, as well as their spatial consequences. Confronted to the Greater-Paris context, it attempts to clarify both tensions and innovations crystallized through the ongoing projects.
