In terms of logistics and governance, ongoing collaboration with various stakeholders had to be sustained throughout the project. The first grand gesture was the creation of a non-profit organization, the Corporation du Domaine du Seigneur Taschereau, in the 1990s to provide project coordination. Given that the park would be springing to life in an area spanning several properties, partnership agreements needed to be put in place with the different landowners, including the City of Sainte-Marie. The municipality showed its support over the course of the project, through funding, its backing of the development of new partnerships (for example, with the local watershed organization) and the granting of permits. The municipality also facilitated the consultation and participation of the local population, which fostered the community’s support of the project. Also, the local business community supported the project from the start, working together to provide funding and project visibility.
From a technical standpoint, the project ended up consisting of the restoration of the marsh, with a surface area of 22,000 m2. After extensive excavation and land-use planning, approximately 27,000 m3 of fill was removed from the site to make room for the new marsh, named Grand marais Denis-Sylvain. The marsh was developed in such a way that it would foster the growth of an abundant and diversified fauna, while maintaining the equilibrium of the new ecosystem (e.g., a sediment control basin to prevent silting). Shallow water areas were created and seeded with 16 species of native aquatic plants. These areas serve as spawning grounds and the plants help to shelter the eggs. The shallow waters also foster nest building and provide food for some species of birds, mammals and amphibians. A fishway was built to help fish move between the marsh and the Chaudière River. Also, 900 trees and shrubs, along with 2,500 aquatic plants, were planted around the marsh so that the fauna can find nourishment, take cover and reproduce.
