CITY CLERK

RECOMMENDATION:

(1) That Council authorize the installation of the structural concrete
work for the proposed Pitt River Road Drainage Pumping Station in
conjunction with the construction of the floodbox through the
Coquitlam River Dyke, as well as the dredging of the slough
upstream of the proposed floodbox at an estimated cost of $175,000.

That the above works be financed utilizing funds from the Tax Sale
Reserve Fund. -

That Staff be directed to prepare a Drainage Works Development Cost
Charge Bylaw to fund the balance of the pump station and other
drainage ‘zorks required in the drainage area tributory to the
Coquitlam River south of the CPR Tracks which are identified in
Associated Engineering's report of April 1990.

BACKGROUND AND COMMENTS:

Associated Engineering's drainage report of April 1990 identified a number of
drainage improvements which are considered to be necessary in the catchment
area of the Coquitlam River south of the CPR tracks. The total escimated cost
of these works is $1,226,000. Not all of these works need to be installed
right away; however, there are economies of seale in constructing the concrete
structure for the pump station as part of the floodbox structure which is paid
for by the senior governments. As well, it is important to provide some
additional storage in the slough to prevent flooding during periods when the
floodgates are closed and there is no pump station in place. These works
should be done in conjunction with the dyking project with the completion of
the pumping station following shortly thereafter.
