In Option 3. Quanta Enterpnises. at their cost. would extend the fll 5 m
horizontally out onto the right-of-way, thus shifting the toe of proposed dyke
5 m horizontally away trom the rear of the townhouses. Any additional fill
for the dvke, should it be constructed, would be at Program expense Quanta
Enterprises are willing to construct the dyke for the Program, either at cost
or at a contract price. In addition, if the dyke is constructed. a fence should
be erected to delineate the dyke and to ensure that the crest is unobstructed.
The cost of this fence, if required, would be shared 50/50 between the
Program and Quanta Enterprises.

If possible, the Program wishes to delay a decision on whether or not to
proceed with Option 3 until negotiations with the Native landowner are
concluded. Should a decision be required before these negotiations conclude,
the Program may proceed with a scaled-down version of Option 3, shown as
Stage 1 on the attached drawing. This would permit full implementation by
placing State 2 fill at a later date.

The overall proposal has benefit to the Program. Firstly, it keeps open our
option of returning to the original dyke alignment. Because of the problems
with the Native landowner, this is becoming more of a possibility. Raising
the entire site of the townhouse development from 3.5 to 5 m provides a mass
fill at elevation 5 m against which to abut a dyke. If the dyke is constructed
adjacent to this fill, it will only have to be 0.85 m in height, and because of
the limited height the side slopes can be steepened to 2:1. The net effect is
that the toe of the fill is kept further away from the sewer line than with the
origina! plan.

Based on the above understanding, we indicated that the Program had no
objection to the 1 m roof overhang of the rear units adjacent to the dyke right-
of-way and that we advised the City of this position in the minutes of the
meeting dated April 14, 1993. This letter will confirm and elaborate on those
minutes.

Yours truly,
