ZAC Nouvelle Centralité

Project overview

© ANMA

This is a state-run integrated development zone (ZAC) designed to serve as a new central hub for Carrières-sous-Poissy. It is a major project in the OIN Seine Aval operation for the downstream Seine area, led by the EPAMSA statutory development body in close partnership with the town of Carrières-sous-Poissy and the Communauté d’agglomération 2 Rives de Seine group of municipalities.

This new eco-district will meet ambitious environmental and energy objectives. For instance, all of the buildings will have to meet the minimum requirement of 60% of renewable energies for heating and hot water.

This integrated development zone has a variety of objectives:

  • Create a place where people live, drawing people from throughout the CA2RS or even further afield;
  • Reunite the town and merge in the districts that today are cut off from the town by a large, run-down central void, by building an urban centre in the very heart of Carrières-sous-Poissy that will draw the town together and attract people from throughout the CA2RS conurbation.
  • Fix up the entries to the town and integrate the existing and planned infrastructures that today help divide the town into two (upgrade the RD190 road, set land aside for the A104);
  • Restore the connection with the broader Seine loop landscape;
  • Give the town of Carrières-sous-Poissy an identity again, raise its profile and restore its urban feel;
  • Launched in 2009, the project extends over 47 hectares of fallow land. It constructs a lasting connection between housing, shops and public amenities around a major public space (the Agora), which largely looks out over nature. A large part is set aside for quality public spaces.

The project to build a central hub for Carrières-sous-Poissy will eventually develop the following:

  • a shopping and leisure centre;
  • an Agora (central public square);
  • an ecological corridor covering nearly 10 hectares;
  • 900 homes in 2013, 2,800 homes by 2023 (10% single-family, 25% intermediate, 65% multi-family);
  • schools, nurseries and leisure centres;
  • private businesses, facilities and services (offices, serviced residences, etc.);
  • a multipurpose venue;
  • a cinema;
  • a cultural facility, the “Fabrique Numérique”;
  • a frequent bus shuttle service to the RER/SNCF train stations;
  • a tree-lined urban boulevard (upgraded RD190 road).

The Nouvelle Centralité operation was designed to blend gracefully into its urban and natural environment. This integration relies on preserving and enhancing biodiversity and the living environment through a landscape design that maximises the site’s plant biodiversity (horizontal and vertical structuring) and animal biodiversity (the entomofauna in particular) by, as far as possible, recreating habitats that are built to last and ready to provide a home for fauna and flora. Preserving ordinary and extraordinary biodiversity on the site entails identifying a north/south ecological corridor. This creates a continuity between the Coeur vert project in the Chanteloup loop and the Seine, via the Parc du Peuple de l’herbe project, enabling species to move around and giving the population a quality recreational area. The proposed ecological channel on the land set aside for the A104 motorway helps develop the ecosystem. And the ecosystem, in turn, plays an active role in the alternative rainwater treatment system by acting as a biological water purifier (the presence of the ecosystem speeds up the decomposition of organic matter). The concept of “nature in the city” proves its worth. Water-related questions have a hand in developing and dispersing the site’s biodiversity, while at the same time improving the living environment. The ecological network approach is aided here by the creation of paths and continuities that connect up all of the nature areas present on the site.
