TOCO is a provocation, a call to action.
Its name says it all: we are all actors, and therefore designers of our territories. Each of us, in our own way, holds a responsibility for the resilience of flood-prone areas.
It’s also a call to (re)invent, to commit, to transform our practices.
This event brought together over 100 participants, for a dynamic cross-sector discussion between:
- Local authorities
- Urban planners, architects, and landscape designers
- Engineers and risk prevention managers
The goal of the TOCO network – led and facilitated by #CEPRI, in partnership with GIP Europe des projets architecturaux et urbains (Daniel Andersch) and supported by the Association Architectes des Risques Majeurs – is clear:
To foster dialogue between urban planning and risk prevention communities, and step up efforts to transform flood-prone areas into ecosystemic spaces capable of responding to ongoing polycrises.
🔍 The discussions were enriched by concrete case studies:
- Jean-Marc Bichat – Germe & Jam – “Vitry-Seine-Gare” project, Vitry-sur-Seine: a dense urban development in a flood-prone zone.
- Cassandre Limier – Métropole du Grand Lyon – “PUP du Train Bleu”, Rochetaillée-sur-Saône.
- Anne-Sophie Huet – Métropole Rouen Normandie – ZAC Luciline, Rouen.
These contributions helped identify the room for maneuver and the barriers—the frameworks that need to be broken—for urban projects to go even further in anticipating crises and enabling recovery.
Many critical questions were raised…
👉 What limits do local authorities and designers currently face in crafting urban projects that better respond to flood risks?
👉 The constraints of the #PPRI (Flood Risk Prevention Plan) provide a framework that encourages creative solutions—but it doesn’t say it all.
👉 Can the narrative of flooding become a tool to ensure that urban projects offer concrete solutions for users?
This first gathering lays the foundation for an ambitious collective dynamic.
A heartfelt thank you to all the speakers and participants for such an inspiring day.
This is just the beginning!
