The Basse Deûle park in Lille is an ambitious project of ecological restoration, combined with the renovation of an outdated park. Located at the crossroads of numerous heavy infrastructures, the dead arm of the Basse Deûle river that gives it its name, and the ramparts erected in the 17th century, the site is rich in historical, technical, and environmental constraints.
The main objective is to accompany and facilitate soft mobility along the river, in order to connect the park to the major greenways that run along the Deûle canal to the northwest and to the heart of Vieux-Lille to the south. A stadium and several family garden areas are also interconnected.
The relief inherited from the fortifications, the presence of degraded historical structures, and the narrow land holdings along the banks have required a careful positioning of the pathways and crossing bridges, both in altitude and planimetry.
In a spirit of unity and integration, we have developed throughout the park a leveling system made up of standardized concrete blocks, serving as both retaining walls, seating and stairs. In the most constrained areas, especially on the riverbanks, the blocks are complemented by the installation of steel supports reminiscent of the canal sheet piles, and densely planted enbankments.
The numerous crossing structures and differences in levels have led us to propose the deployment of custom-made guardrails. Inspired by the industrial elements present on the site, it unifies the new walkways and stairs with the rampart remnants that needed to be secured.
In collaboration with our ecologist and in order to restore the site’s environmental quality, we have established a palette of plant species, mainly local, adapted to the different environments ranging from forest-like woodland to herbaceous riverbanks. We paid particular attention to the restoration of riverbank and alluvial forest environments that are the most degraded and impacted by the project. Everywhere else, the conservation and strengthening of existing plant structures were a priority.
