lots remain unoccupied. Based on the current rate of usage, it
is anticipated that expansion of the designated burial area to
the north will be necessary within the next two years.

Sub-surface soils investigations at various locations
in the Cemetery indicate that there exists a continuous layer
of hardpan at depths ranging from 0.3 to 0.9 meter from the
ground surface. The slope direction of the hardpan surface
corresponds well to the natural ground slope. Above the
hardpen layer are soils consisting of gravelly sands, silty
sands and top soil. With this type of soil conditions, it is
likely that the groundwater problem is caused by one or a
combination of the following:

1. surface water percolating through the ground reaches
the hardpan then follows the surface of the hardpan
to lower areas.

springs surfacing itself through faults in the
nhardpanm’then follows the surface. of the hardpan to
lower areas.

In order-to solve the groundwater problem it is
therefore necessary to intercept the groundwater flowing into
the burial areas as well as draining groundwater away from the
burial areas. A system of sub-surface drains consisting of
perforated pipes installed in a trench filled with drain rock
will achieve these objectives if the depth of the trench is
below the surface of the hardpan. For economic reasons, the
trench depth need not be greater than approximately 0.3 meter

below the hardpan surface whenever grades permit. Appendix B
shows the proposed sub-surface drain system and the future
layout of the Cemetery. The proposed drains consist of two
separate systems; one for the existing and the other for the
future burial areas. . With the installation of drains in the
existing burial area, it should be noted that there is some
likelihood that during the first few days of operation some
odor may be detected in the ditch into which the proposed
drains outfall. The odor should disappear once the stagnant
water in the existing graves has been drained.

Financial Impact

The total estimated cost for the proposed sub-surface
drain system is $27,000. This estimate was prepared based upon
the final unit cost for the installation of similar sub-surface
drains in Thompson Park earlier this year. For comparison
purposes the separate costs for the proposed drain systems in
the existing and future burial areas are $11,000 and $16,000
respectively. From a strictly cost benefit point of view, it
is obvious that the installation of drains in the future burial
area would result in greater benefits. However, it may be
