The Bamfield Road Surfacing Project experienced it’s first heavy rainfall and we are happy to let you know that no sediment has gone into the river!
What did the crew do to prepare for this?
Along the bank of the river and lake, where the road is higher than the body of water, they line it with riprap. Riprap are large rocks (a foot or bigger). They are placed tightly together along the banks so when the rain is hitting the road and draining towards the river or lake, the sediment gets filtered through the riprap. This works both ways as well. When lake and river waters rise from a lot of heavy rainfall, the riprap will prevent the road from getting washed away from these rising waters. This is an important feature to protect our wildlife and keep our drivers safe. Good job road crew!
Ditch You Know?
The new ditches have all been hydro-seeded or hand seeded and new growth has sprouted for many kilometres. While we wait for the grass to grow, rock check dams have been placed in the ditches to reduce the flow rate of water, which allows any sediment to settle out. The runoff is being monitored by the team and they are checking critical areas to ensure there is no impact to the waterways.
