Since Penny Dimour moved to Lower College Heights in 2013, the trails behind her house, on the banks of the Fraser River, have changed drastically.
“Over the past three years there’s been a lot of erosion. The bank is changing pretty much as we speak.”
Over the years the flow of storm water has carved a near vertical ravine down to the river.
“At night you can actually hear rocks falling down pretty much hourly. There was a lady last year that lost her dog down there. An older dog and I just thought that a dog is important obviously. But if it was a child that could be very dangerous.”
This spring, the City will begin work to stabilize the storm drainage outfall that discharges into the river. The cost of the project $1.41 million dollars. The provincial and federal governments will each contribute $470,000 to the project. The rest of the bill will be covered by the city.
Project Manager, Chris Vliegenthart says the City has had it’s eye on the problem since 2012.
“At some point the natural drainage channels hit a critical point where the waters reached the highly erodible soils that are beneath the surface. At that point it’s continued to erode at roughly 1000 cubic metres a year.”
Vliegenthart says the City’s plan is to put a storm water management system in place that will channel water down the river to stop the bank from eroding.
“This spring we’ll be starting the excavation process of approximately 18-thousand cubic metres of soil and then we’ll start the installation of the pipe and the rip-wrap that will convey the water down to the river.”
Crews will start work by removing fallen trees from the ravine. Actual construction is set to begin in the spring and the hope is that it will wrap up by the end of the fall.
The City asks that the public avoid the area until the project is complete.
For Penny Dimour and the rest of her neighborhood, they look forward to being able to walk down by the river once again.
