Here's a master plan they call Interives in Orléans, stretching over 110ha (~270 acres) of urban wasteland.
The affected area from above, along some rail tracks at the northern edge of the city, I believe.
There used to be some (likely cheap) housing built in the 1960s. That's what the master plan is to replace.

For now, some 3000 new residential units are planned, and 350,000m² (3.5+ mi sq ft) of offices, hotels and commercial space. Some urban cable cars are supposed to allow the crossing of the rail tracks.
This will be the main master plan and development opportunity to work on in Orléans for the coming decade.
