Potential effects and mitigation measures
- Disturbance or displacement of wildlife.
- Removal of/damage to trees, terrestrial vegetation and wildlife habitat.
- Potential impacts to aquatic/riparian vegetation.
- Potential erosion and sedimentation.
- Maintenance activities may result in disturbance/loss of vegetation and habitat.
- Sensitive-wildlife timing restrictions for construction activities (e.g., removal of vegetation outside of the breeding bird season).
- Wildlife exclusion measures will be implemented as required to avoid destruction, injury or interference with wildlife species and their habitat.
- Tree/vegetation removals will be kept to a minimum and limited to within the construction footprint.
- Temporarily disturbed areas will be restored/re-vegetated using non-invasive, preferably native plantings and/or seed mixes.
- Construction activities will maintain buffers established during the design phase to minimize potential impacts to wetlands and waterbodies.
- Erosion and sediment control measures will be implemented.
- Vegetation removal and habitat disturbance will be kept to a minimum and limited to within the Metrolinx right-of-way.
