PRELIMINARY PLANS
9
No overlap of the 10 m riparian buffer zone
0,27 ha wetland lost (+/- 0,1 ha for the avenue)
![Page 10: ENVIRONMENTAL UPDATE · environmental update general information meeting for mckenzie avenue extension project may 24th 2016](https://reader034.vdocument.in/reader034/viewer/2022051911/600214610fdbb402506d3de0/html5/thumbnails/10.jpg)
AVOID → MINIMIZE → COMPENSATE
• Overlap of the 10m stream riparian buffer zone avoided by shifting the avenue inside the cadastral limits
• Unable to avoid wetland, minimization of perturbation by ensuring residual wetlands will continue to receive sufficient water
• Loss of wetlands requires compensation replacements

Possibilities are :
• Land conservation
• Re-naturalization of disturbed habitat
Best option is partial acquisition of McGill land
• For acceptation by MDDELCC, need to prove that proposed conservation is an environmental gain
