PRELIMINARY PLANS

9

No overlap of the 10 m riparian buffer zone

0,27 ha wetland lost (+/- 0,1 ha for the avenue)

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

PROJECT ANALYSIS

10

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

COMPENSATION

11

Compensation concept proposed
