The Passo de Estrela Memorial Ecological Park was established where the Passo da Estrela neighborhood once stood, which was destroyed by the tragic flood of 2024. In 2025, through the initiative of SEDUR (Government of the State of Rio Grande do Sul), the park was created to be a leisure area resilient to future extreme climatic events and, at the same time, a living memory of the neighborhood and the history that once existed here. Spanning 250,000 m², the park is characterized by floodable and wetland areas, biodiversity islands for water retention, recreational and sports areas, and spaces where the material and immaterial memory of the neighborhood is preserved. Some elements that remained after the floods were preserved as testimonies to the tragedy, serving as monuments for memory and awareness for future generations. A system of rain gardens integrated with wetland areas, permeable paving, and native vegetation creates an environment where water becomes an integral part of the landscape, people's lives, and a structuring element for the creation of multiple ecosystems.
