Water main construction

Bad enough the oil companies want to trash portions of the farm, see an older posting;

       This Water main project to Port Mann, in Surrey, was actually started before the oil pipeline project by Metro Vancouver, and being that it is a government project it grinds along like a glacier; and as usual it ran into problems that required complicated fixes; SEE: Drilling to resume on stalled Metro Vancouver water tunnel for Surrey area

       I was sent a report today, created by:  Diamond Head Consulting Ltd., entitled:
  Arborist Report Portman Main No.2, North, Coquitlam, B.C. updated 19 January 2015 (2869K) PDF.  No idea where the name of Portman comes from, should read Port Mann I would think, because that is where this water main is going.

And also a map Portmann Main #2 tree retetnion and removal   19 January 2015  (PDF)

       I spelled it the way it was written, so we are getting a little closer to Port Mann, but fail in the spelling of "retention".  The last PDF is a map of the areas being impacted by the water main going through the Riverview Hospital property.  Another nasty scar slashed through the landscape, from Riverview hospital up near Mariner Way, through Colony Farm, through its critical habitat treed wind-break to go under the Fraser River near the Port Mann bridge, and into Surrey and beyond.  

Port Mann is named after Sir Donald Mann and  most of the area that we know as, Port Mann was previously known as Bon Accord, prior to the railway yards being built there.  A salmon hatchery, and a salmon cannery were once in the area, both named Bon Accord.

 The project is part of  the Port Mann Water Supply Tunnel  read the PDF factsheet
From what I understand the numerous pipelines (gas,oil,water,communications) under the river at this point have had issues with the river exposing them, which places large stesses upon them.
