Project description
Name of the case study
Lyon Confluence Storm Water Management
Description of context
This case study is strongly embedded in a context characterised by political forces. Indeed the project Lyon-confluence is one of the biggest since several years in Lyon, whose influence is national. The impacts on Lyon vitality and way of life for the Greater Lyon’s inhabitants are significant. And that’s why it represents a great challenge that the city should overcome.
Description of project - background
“Lyon Confluence” is one of Greater Lyon’s biggest projects. It is a long-term project, planned until 2030 which consists on the renewal of an old industrial area into a downtown district.
Located between two rivers, Rhone and Saone (see figures 1 & 2), and long restricted to industry and transport facilities, the peninsula is undergoing a transformation, a complete and extensive change.
This strategic territory is now being prepared for the function it should have had due to its central and pivotal location at the south of Perrache railway station (see figure 1): a true city-centre.

It is planned that around 2030, 25 000 inhabitants should live in the project area, 14000 employments should be created by the coming of new leisure and cultural infrastructures and a wide place of green space should be reserved (30-40 ha).
