Does CLOCA not consider the entire forest?

What about the eastern forest which is according to Attachment #6 going to be swallowed up in it's entirety with Type 3 building?  The eastern forest is a much more significant forest than the western forest.  Has CLOCA staff taken into consideration the berm to be built along the railroad property and the fence that the railroad is requesting, when they note that the western forested section of the site appears to be excluded from the proposed development?

CLOCA staff note that the extreme western tip of the property drops off into the Pringle Creek Valley. This forested section of the site appears to be excluded from the proposed development. CLOCA recommends that the forest edge be maintained as much as possible as a limit to development on the property.

Canadian Pacific Rail
1. Berm, or combination berm and noise attenuation fence, having extensions or returns at the ends, to be erected on adjoining property, parallel to the railway right-of-way with construction according to the following: a) Minimum total height 5.5 metres above top-of-rail; b) Berm minimum height 2.5 metres and side slopes not steeper than 2.5 to 1; c) Fence, or wall, to be constructed without openings and of a durable
material weighing not less than 20 kg. per square metre (4 lb./sq.ft.) of surface area. No part of the berm/noise barrier is to be constructed on railway property

Will this berm be able to be built without destroying the western forest?  NOT LIKELY or at least not in my opinion.
