  • by rethinking the mobilities and the place of the car,
  • developing the range of equipment, especially around children,
  • offering new services, particularly around health,
  • by improving the supply of housing (seniors and social rental). This project is part of an exemplary approach to its governance and design. It pursues ambitious objectives on the ecological level, and more generally on the 3 pillars of sustainable development, while remaining coherent and realistic with the financial capacities of a small municipality in rural areas.

  • Establishment of shaded spaces on the public space, and maintenance of a sunny area for the winter.
