Summary of the Initiative

On May 30, 2026, a new permeable, tree-lined park was inaugurated at the intersection of Avenue des Acacias, Avenue de Mon-Loisir, and Avenue de Montchoisi, during a participatory planting of perennials. This milestone marked the end of the participatory process.

The participatory approach in a few figures:

• 4 meetings between June 2025 and May 2026

• 150 participants across all stages of the process

• 44 new trees, 29 more trees than before

• 81 shrubs and 500 perennials planted

• 1,165 m² where the asphalt was removed

• 3 tables, 6 benches, and 3 log benches to furnish the site

A Look Back at the 4 Meetings

The presentation session was held at the start of the project. It was during this session that the first concerns were raised about the cherry trees that were going to be replaced.

The tour was then led by the City of Lausanne’s tree commissioner and the project manager from the Parks and Public Lands Department. This tour allowed those in attendance to explore the project firsthand on-site.

Despite the rain, the participatory permeabilization project took place in a cheerful atmosphere. Those in attendance removed about 100 square meters of asphalt, and signs were created to announce future plantings.

The initiative concluded under sunny skies and sweltering heat with the inauguration of the small plaza and a participatory planting of perennials. Feedback was collected, notably through an online survey on the Lausanne Participe platform.

A valued and necessary initiative

Overall, the participatory approach that guided the project met the expectations of those who shared their views. The majority of participants were neighborhood residents who appreciated the opportunity to get involved in creating a new space in their neighborhood. The chance to make a tangible contribution was also highlighted. The organization, hospitality, and friendly atmosphere made each meeting a positive experience.

Concerns were raised from the very beginning of the process regarding the removal of certain trees. Responses were provided at each stage of the process, notably assuring that the new tree species would result in much more substantial growth and beautiful blooms.

Perspectives

Among the areas for improvement raised, some people would have preferred an approach that was less informative and more consultative. There were also requests for better communication to help people understand the issues involved in this long-term project.

Several proposals reflected the neighborhood’s ongoing process of taking ownership of the space: organizing workshops, meals, and board games, and continuing on-site activities throughout the different seasons.

This feedback will be taken into account in upcoming participatory initiatives related to the city’s adaptation to climate change, particularly the creation of the Dapples neighborhood garden.
