Technical Volume 10
Hydrology Impact Assessment
Technical Volume 10 is an evaluation of the potential impacts of the proposed construction of the South Fraser Perimeter Road on the groundwater quantity and quality conditions.
This Volume shows that the SFPR will impact the Bog by being as close as 50 m to the inferred mound, running through the lagg zone along many of the sections and interfering with the conductivity of the acrotelm layer. It is also acknowledged that highway run-off water would have a significantly negative affect on the quality of the groundwater in the Bog, but the proponent does not say what mitigation measures would be put in place to capture and prevent highway run-off from changing the water chemistry of the Bog.
These impacts are not only of great concern to the public and are reiterated in documentation from the Burn¥ús Bog Society, Delta Council and the Scientific Advisory Panel. For many years these agencies have voiced concerns about people walking in the Bog because of the potential for damage to the delicate Microsystems by foot traffic, so how could a 4 lane highway be built in such close proximity to the Bog without substantial negative impacts?
The construction of a major roadway along the northern and western edges of the Bog would mean serious detrimental impacts that would threaten the life of the Bog, and would be contrary to the principles of the protective covenant that is in place to protect the Bog. Therefore the current plans for the SFPR in this area should be dismissed and alternative routes that avoid the north and west sides of the Bog should be sought.
Reference locations in the document and the applied reasoning that resulted in this review summary will be coming soon.
