Team Point of View

Climate change is increasing torrential flooding and soil erosion, amplifying sedimentation on the plain. The project takes advantage of flooding to recover silt from the Isère and produce local topsoil, which is used to green the town centre. A new territorial metabolism is thus established through the transfer of organic matter.
This metabolism is supported by four landscape figures: the sedimentary marsh, a wet landscape that allows the silt to settle; the forest avenues, historic routes that refresh and clean up the dense city; the woodland crossings, a network of gardens linking the plains and foot-hills; and the archaeological loops, a narrative trail following the traces of the ancient meanders of the Isère River, providing a scenography of the risk.

Jury Point of View

The team puts forward a long-term argument for its proposal by considering the glacier melting that is already underway, future water shortages and the disruption of sedimentary dynamics on the scale of the watershed. Armed with this forward-looking scenario, it looks at the site from a distance and seeks new representations to bring the Boucles de l’Isère park into existence. The jury picked out this proposal for its originality and its ability to conceptualise and tell a story about a territory that continues to change with and through its sediments. The project also displays great qualities its work on soil, water and plants.
