Attention: Janna Taylor, Director of Parks & Recreation.
Dear Ms Taylor,

rea; Riverwood Community School Site Development
Geotechnical Report.

Further to our telephone conversation with reference to the
Geotechnical Report prepared by Golder Associates Ltd., with
reapact to the s0il conditions in the Riverwood School site
development area. The geotechnical site review was undertaken at
the request of the City Engineering Department to provide input
for the feasibility assessment for construction of a National
Standard 400 4etre Running Track and Field Event Facilities at
the proposed school site location.

The scope of the review was limited to providing comments for
conceptual planning related to the site preparation for
construction of the track and field facility. No site
investigation, sampling or testing of the seil or ground water at
the site was carried cut specifically for the present feasibility
assessment. The comments presented in the report are based on
limited available soil information from previous soils
investigations carried out in the Port Coquitlam area and
geotechnical data derived from projects in the vicinity of the
gite which gives an indication of the probable soil conditions
existing in the area of this particular site.

As requested we have met with Mr. Colin L. Y¥. Wong, P. Eng. of
Golder Associates to review his report and the probable soil and
ground water conditions which exist at the site and to address
the potential settlement problems which would have to be
considered for the design and construction of the track and field
facilities.

There are a number of foundation treatment optiors which will
allow achievement of the 1 - 1000 differential settlement
tolerance for the track and field facility which are outlined in
the geotechnical report. Other options will be apparent when
further site investigations are completed. In the design
considerations for construction of the running track any
foundation treatment required will be confined to the area of the
running track only and not necessarily to the remaining open
space areas available for ar Sate Toe and park uses.
