Some are called to disappear others in turn

After Seine downstream and the Mantois, the territory immediately upstream of Paris was built in operation of national interest (ISO), public institution for the key development in May 2007. Twelve communes, Ivry-sur-Seine to Ablon, up the River about 15 km, with particular Orly Rungis on the left bank, Alfortville and Villeneuve-Saint-Georges on the right bank. Two years later, in April 2009, public development is approve the strategic project Director (PSD) of this vast area of 72 km2, counting 335.000 people and 160,000 jobs, very fragmented industrial right-of-way that colonize and rail and road infrastructure that cross. Clippings that are opportunities for service and enclaves which have a strong potential... Paradoxes and contradictions that ISO proposes to go beyond mobilizing a significant land strategically located a few kilometres south of Paris. "Mesh, connect, create synergies, reconcile (industrial) nuisances and (flood risk) with planning to operate a true urban metamorphosis," States Jacques Touchefeu, Director General of the EPA, which uses the metaphor of the rough diamond to be cut to make it shine.

At the crossroads of the lines

For bringing the action, the PSD based on the principles of the Grenelle of the environment distinguishes 6 sectors with strong issues with reference schemas. The Ardoines is the first of them coming from Paris. Entirely located in the territory of Vitry-sur-Seine, it is the most advanced in operational terms. This land 300 hectares, clearly circumscribed entity presented in the form of a Crescent stalled in the curve of the River contained by the rail beam that borrows the RER C, with Vitry stations and of Ardoines at both ends. Its strategic position is confirmed by the project of Metro to bypass the great Paris whose transverse route passes through the Ardoines station and coincides with the Arc Express envisaged by the region and its Union of transportation (STIF), called Orbival in the Val-de-Marne crossing. In parallel, new road crossings are also programmed over the rail beam and the Seine, reinforcing the idea of a major multimodal crossing at the Ardoines.

This revelation of the site is also aided by transfers expected large industrial enclaves that shape: Central thermal EDF, BP oil deposit, Sanofi-Aventis research centre... Some are called to disappear, others in turn. The plan guide, designed by architect and urban planner David Mangin (Agency Seura), said the new deal without forcing fate. "We are dealing with a site that still produces many but which must be prepared to deploy to achieve compliance with the regulation of Grenelle and soon Copenhagen, observes David Mangin." Some companies have already committed their mutation, as Sanofi-Aventis refocuses on the research or EDF queries on the reformatting of its central since coal poses problem. In addition, all of the site is flood. We therefore looked for solutions in a realistic urban mutation. "The plan guide lists the scenario for the next decade and beyond. It takes note of the action committed in the vicinity of the two existing of RER C stations, timing will be doubled before 2017, and implementation interconnection expected at this time to constitute a pole of trade in the great railway Hall throne next to the current of the Ardoines station. Soon decommissioned in all, this double nave of 150 metres in length is unanimously. "If there was a building on the area to keep, this was it," enthuses David Mangin, touting the beauty and light interior of this "concrete cathedral". Huge volumes are a pole of any found exchanges, in a neglected of 8 to 10 hectares. The plan guide organizes the sector from this iconic and strategic point. Expressed in broad outline, it chain new bridge by a transverse highways along the Sanofi-Aventis site, trace a large boulevard in the North-South axis of the Crescent, redraws the edge of the Seine with shoreline Park and built the flood site levels.

"City traffic".

Finally, it installs the city on the present and future, wildfires this "bandwidth"expensive city to David Mangin, born frame tightly in place of industrial enclaves of 10, 20 or 30 hectares. The closure of the coal plant is scheduled for 2015 and its dismantling in 2020, with the exception of the two chimneys which may be retained for their MSDS dimension. 650.000 M2est program already arrested to invest first released land, distributed parity between real estate residential and real estate commercial including 95,000 m2réservés to biotechnology, with incubator and incubator companies. The developer intends to take advantage of the neighbourhood of Sanofi-Aventis, which is investing 200 million on its site (9 of the area private research), to participate actively in the development of the Council of Ile-de-France "biocluster" emerging South-East of Paris. "It's here to addition of industrial entities in an open city combining habitat and activities taking advantage of the great landscape of the Seine", summarizes the Jacques Touchefeu developer the Ardoines sector is one of six fire irons.
