Finn Creek Crossing was deemed to be at risk of damages due to natural hazards and continued erosion along the river had left the pipeline without adequate protective cover.
Remediation included the delivery and installation of rock riprap along the stream-bed and stream banks. The work included exposing the pipeline through the channel and removal of coal tar coating, inspection and recoating the pipe. The pipe is further protected by the installation of precast concrete
swamp weights anchored to lock-blocks embedded on each side of the pipeline
For environmental reasons, the work site had to be isolated from the flowing waters. Due to high water flows, the stream flows had to be diverted through an excavated
channel around the worksite. Stream diversion and dewater pumping had to be maintained and supervised throughout the duration of the project.
