This urbanisation project (solely devoted to housing) is set within municipal limits, right by the River Seiche which produces substantial wetlands.
A growing environmental awareness has led to a proposal to unify the various areas of ecological concern surrounding the site by maintaining a physical continuity between them:
- Enhancing and integrating existing wetlands into the project by creating new wetlands
- Creating a “semi-wild” strolling area as a transition from the existing urban park to the Seiche riverbanks
- Increasing wooded areas (carbon sinks)
- Gathering as many technical holding basins as possible and using landscaping techniques (gentle slopes, gullies, ditches)
- Restoring the Mécanique brook to open skies in order to reduce its downstream flow
- Supply water to the wetlands and to the Mécanique brook downstream by using the neighbourhood’s rainwater
Meanwhile, special attention is focused on landscaping the borders between public areas and private plots by taking advantage of the existing groves and copses which are still widespread throughout the site.
