Challenge / Goal

The Parc de la Theuillerie redevelopment project in Ris-Orangis, Ile-de-France, aims to make significant improvements to various aspects of the urban space. It seeks to increase the use value, accessibility, appropriation and integration of this park and cool island into the city. It also aims to optimize the management of this urban space to ensure its sustainability.

To achieve these transformations, the project aims to build consensus among a wide range of stakeholders, including residents, users, local associations, municipal services and elected representatives. In addition, it seeks to capitalize on the expertise of residents and local players to stimulate local development and improve the community's quality of life.


This case study is structured in three main stages:

The first stage is a shared diagnosis (8 months). Six co-construction workshops with various types of inhabitants (schoolchildren, women from immigrant backgrounds, residents, workers from the business park), twelve semi-structured interviews with local players and observation sessions were organized. This was followed by a "Vision Commune" workshop, bringing together these different audiences with local associations, municipal services and elected officials, to establish short-, medium- and long-term priorities. A festive "Fête de la nature" event was scheduled in the park, helping to raise the profile of the area and prefigure its uses.

The second stage is the development of scenarios (4 months). Different scenarios and references for specific spaces were presented to local residents, who ranked the proposals in order of importance. These proposals are then costed by the prime contractor (Groupement Alt) and presented to the city's departments and elected representatives.

The third stage consists of drawing up a development, management and animation plan for the park (4 months). This is achieved through workshops with residents and the park's technical services. A festive feedback session enables residents to take a step back from the process and make suggestions for improvements.

Citizen participation

Users are at the heart of the process. They are not only invited to co-design the project through workshops, but also to contribute to the programming of festive events and give their feedback on the process. This case study illustrates how to create a social dynamic and anchor an urban project in the local area.
In the name of public action readability, the whole process is also recorded and will be shared in the form of podcasts by a journalist.
