Green's Creek Watershed _CCN
National Capital Commission (NCC)
Environmental and sustainable benefits
- Protection of natural habitats
- Sustainable stormwater management
- Creating ecosystems and green corridors
- Increased biomass
- Lower infrastructure costs
- Lower maintenance costs
- Quicker approvals time for permits (MELCC, etc.)
Located in the Ottawa’s Green belt, Green's Creek Watershed covers approximately 12,000 hectares. Shoreline erosion of the tributaries is spreading on both Green's Creek and Mud Creek, which affects soil stability and water quality in the natural environment of the entire watershed.
The task given to Groupe Rousseau Lefebvre was divided into three stages: analysis of existing reports, field surveys and inventory, site analysis within the watershed and the presentation of planning concepts to solve the issues raised by the National Capital Commission.
Our recommendations focused not only on emergency actions for stabilization through phytotechnology, (bioengineering), but also on solving existing and potential stormwater management issues impacted by the urban development upstream within the watershed. Recommendations on the landscape seen from the roadways have also been proposed to insert the planned interventions within a dynamic visual sequence across the identifiable stretch of land .
This project required a multidisciplinary approach upon the whole territory, which was an objective promoted by our team. Therefore, soil stability, slope factor (geomorphology), sedimentation, stormwater management, flora, fauna and landscapes were all determining factors in this study.
