Description of context
Description of project - background
The “Lyon Confluence” is one of Greater Lyon’s biggest projects. The project consists of the urban renewal of an old industrial area into a city centre district.
Located between two rivers, Rhone and Saone (see figures 1, 2 & 3), and long restricted to industry and transport facilities, the peninsula is undergoing a transformation, a complete and extensive change.
Figure 1: Lyon-confluence limits defined by 2 rivers.
This strategic area is now being prepared for a new function which is more appropriate due to its central and pivotal location south of the main Perrache railway station (see figures 2 and 3): a true city-centre location.

The site of Lyon Confluence, an essential core transport junction, spreads over 150 ha, including 30-40 ha allocated for urban residential areas (7000 inhabitants), 70 ha for industrial infrastructures and 5 km of riverside facilities. It is planned that by 2030, 25 000 inhabitants will live in the project area, 14000 employments should be created by new leisure and cultural infrastructures and a large green space should be reserved (30-40 ha).
Description of project - objectives/aims
a)Long term project
The long term project (2030) provides the major objectives to give the area a unity and the main urban development principles of development of a continuous entity, of mixed functions and of new communication ways with the other parts of the town centre.
The main objectives of the project can be summarised as follow:

Several objectives are crucial for the success of the project:
In order to achieve this long term project, some constants have been specified. It is actually very difficult and perilous to fix rigid predictions on urban development for 30 years because of technologic evolution, political changes... Moreover it is necessary to leave capacity for change in the urban development to take into consideration inhabitant’s opinion and their potential evolutions. The continuous adaptation and adjustment of this project, essential for its success, should come about without jeopardizing internal consistency. That’s why some general constants have been provided and act as fundamental elements for the project structure.
b)The first stage development (12 years)
Some specific objectives have been presented:
This short term development project has been voted by the Greater Lyon in 2003 to include the procedure of a Concerted Development Zone (CDZ- see below description of tools). Components of a CDZ are:
- Leisure-culture spaces
Description of project - time interval and stages
The project presents a step to step land planning:
Furthermore, temporary developments have been implemented to allow the continuity of the project trough the different stages:
- temporary walking tours on the Saone river
Description of project - financing
Description of project - other sectors involved
Up to now, the urban and architectural project of the CDZ has been approved by the Greater Lyon and technical studies have begun.
Simultaneously the Confluence Museum project has been launched. It is lead by the Rhone department and thus does not belong to the CDZ.
