NCWSS - Environmental stewardship
Three sections of the feedermain run through natural areas:
- Nose Hill Park
- The pathway area adjacent to Hidden Valley Drive N.W.
- The area around West Nose Creek and 112 Avenue N.W.
As part of the detailed design, the project team conducted a biophysical impact assessment (BIA) and tree inventory.
The project team is working with other areas in The City to ensure the impact to natural areas is limited and wildlife and fish habitat are protected.
Biophysical Impact Assessment (BIA)
A Biophysical Impact Assessment (BIA) assesses the impact of a project on environmentally sensitive areas. The BIA methodology was developed to meet The City’s Biophysical Impact Assessment Framework.
The conditions of the existing environment are compared against the project components and activities to identify potential impacts of a project and recommend efforts to mitigate this impact.
While The City makes every effort to avoid impact to trees, sometimes the nature of capital projects require that some trees are removed.
When trees are impacted in manicured areas, a tree protection plan is created that first attempts to protect the tree during construction and if not possible, tree compensation is applied to replace the lost trees.
Tree compensation is based on the value of the impacted trees, which is determined by considering the health, size, species and location of the tree using standard international methods. Replacement trees are planted in the closest suitable location to replace the impacted trees.
