Dear Sirs:

Re: Port Coquitlam Trunk Sewer — Cedar Section

In reply to your letter dated September 18, 1990 regarding the design of
the existing 1060mm (42") diameter G.V.S.&D.D. trunk sewer, please find
enclosed a mark-up of a portion of our Fraser Sewerage Area map showing the
area tributary to this trunk. This trunk is designed to service the
northern portion of Port Coquitlam and, by future extension, the northeast
sector of Coquitlam. The routing of this future extension will be
determined in consultation with yourselves and the District of Coquitlam.
Please note that the design of the existing trunk sewer did not include the
area within the Agricultural Land Reserve (RRL-3) as highlighted in green.
This area lies outside the Fraser Sewerage Area boundary.

In regard to your future servicing plans for the Northeast sector of Port
Coquitlam, the G.V.S.&D.D. requires a formal request from the City of Port
Coquitlam to include areas presently not within the Fraser Sewerage Area
boundary. Since the proposed boundary expansion area was not considered
when the G.V.S.&D.D. facilities serving Coquitlam, Port Moody, and Port
Coquitlam were designed, a reassessment of these downstream facilities by
the District will be necessary. All additional capital and operating costs
associated with the up-grading of our facilities, required to accommodate
the boundary expansion, need to be determined. A recommendation to our
Administration Board regarding this boundary expansion would include our
assessment of the way in which facility up-grading costs should be
apportioned and which costs should be borne by the City of Port Cc~uitlam.

In the interim, we will commence a re—-assessment of the trunk sewer
capacity based on the data you have provided.
