This and the following day’s shots are from the same condominium project in Vancouver, B.C., Canada.  We built these retaining walls.  I think we used something like 7,000 for the overall project, an immense project about 2-3 blocks in length.  To the right of the privacy screen trees is the street and a slope seriously downward off to the left.  Grade changes were all over this one.  The pics above were taken about 8 years after the installation.

Note the incredibly large blossoms of the Rhododendrons on the left. These, Azaleas and a tremendous amount of other hugely flowering Spring blooms make the Northwest a landscaper’s paradise. Now, if they could just get rid of the rain!
