Key Considerations
Environmental
- Archaeological Resources
- Built Heritage (two listed Cultural Heritage Landscapes, one potential Cultural Heritage
- Landscape, one listed Built Heritage Resource)
- Sutherland Wesleyan Methodist Cemetery and Rogers Cemetery
- Contamination (areas of medium and high potential contamination)
- Fish and Fish Habitat (specialized habitat)
- Groundwater (Highly Vulnerable Aquifers, domestic water wells)
- Land Use (Greenlands, Strategic Settlement Employment Area, Agricultural,
- Surface Water (drainage, multiple coolwater and unknown thermal regime watercourses)
- Terrestrial Ecosystems (Species at Risk, unevaluated wetlands, woodlots)
Transportation & Engineering
Engineering
- Traffic weaving analysis between the freeways and the adjacent interchange (Simcoe County Road 88 Interchange)
- Traffic Operations based on demand and level of service (LOS)
- Complexities in Traffic staging and constructability
- Structural / grading considerations
Property Impacts
- Lands required may extend beyond the 2002 Approved EA ROW
