How participative metropolitan planning can really work

In 2016, the Grand Paris Metropolis (FR), in partnership with the government and the public body responsible for building the new automatic Metro, launched the “Let's reinvent the Grand Paris Metropolis” challenge for its municipalities and for the private sector (companies, designers, promoters, investors). The challenge included two phases. First, mayors proposed public land and sites in need of transformation. Following visits to these sites and consultations with locals, private sector companies submitted innovative projects for the sites’ economic, social and environmental transformation. In March 2017, 164 projects out of 420 were successful, focusing on 57 sites, 27 of which are around future Metro stations. These projects are made up of more than 326 innovative startups, associations and SMEs. In total, 6.4 billion euros will be injected by the companies acquiring the sites in the coming years.
