Eco-District at the Banks of the Bohrie Ostwald

Creation of new green areas, Other

The design of the district is guided by 6 objectives. The environmental aspects of these include: - Creating a landscape around water. - Living in nature. The district provides the means for flood prevention, communal gardening, (Ref. 2) sustainable consumption, (Ref. 7) waste reduction, (Ref. 5) sustainable consumption with vegetable gardens, (Ref. 7) socially integrated greenery (e.g. community gardens, (Ref. 4) and waste reduction with composting (Ref. 5) Large space will be left from urbanization and filled with: renaturation space for biodiversity development (such as fauna), moisture demanding plants to store the water in case of flood, conserved woods, family gardens (Ref. 2). Water is staged in natural spaces (ditches, ponds, wet meadows, etc ...) such as the Bohren pond, the river Ostwaldergraben, and the seasonal wetlands, developing particular vegetation. Shallow ditches will be dry in normal weather, and filled with water after the rains. The water will then go to the Ostwaldergraben (Ref. 2).

After consultation and research was carried out from 2000 by Strasbourg Eurométropole, in collaboration with the City of Ostwald, on the "Bohemian shores" guidelines for a project constructing a new residential area in line with sustainable development were adopted on October 23, 2009 (Ref. 1). In January 2011, Eurométropole entrusted the operation to a development concessionaire following a competitive tendering procedure: SAS Rives of Bohrie. This company is composed of two developers: CM CIC SAREST and Nexity - Foncier Conseil (Ref. 2). The first installment of real-estate and urban development was made in 2012, and first inhabitants moved in 2014 (Ref. 8). The project is expected to be completed by 2026 (Ref. 7). The district will include green roofs, inhabitants contributing to the maintenance of the district's green spaces (e.g. house and community gardens), (4) vegetable gardens, (7) and composting, while on-site vegetation will participate in the deployment of green infrastructure (Ref. 5). "A large place will be left free from any urbanization. Indeed, of the 50 hectares of the project perimeter, only 30% of the surface will be urbanized. The free spaces will be occupied by: a hygrophilic meadow (plants that need a lot of humidity to develop) in a slight depression compared to the built-up areas and allowing water to be stored in the event of a flood, a renaturation space allowing biodiversity to develop - this space is already in place and under management by the Alsatian sites conservatory, two existing woods kept by the project, a space dedicated to 90 family gardens, a market gardening space, the Bohrie lake and its banks fitted out as a walking area" (Ref. 2)
