Seaspan | Ship Load-Out Gravel Bed and Shoreline Protection

January 27, 2020

Project status

Permit under review

In January 2020, Seaspan ULC submitted a project permit application to construct a ship load-out gravel bed in Burrard Inlet adjacent to their facility located at 10 Pemberton Avenue in North Vancouver on federal lands and waters managed by the Vancouver Fraser Port Authority.

As part of the Project and Environmental Review for the proposed project, consultation with Indigenous and stakeholder groups is required. The port authority is conducting formal consultation activities with stakeholder and Indigenous groups as part of the permitting process.

About the project

Seaspan ULC proposes to construct a ship load-out gravel bed in Burrard Inlet adjacent to their facility in North Vancouver. The gravel bed (7,500 m2) is proposed in order to launch newly constructed Canadian Coast Guard and Royal Canadian Navy vessels. Vessels will be launched by submerging a careen to rest on the gravel bed, allowing the vessels to launch. Seaspan also proposes to install slope protection using rip-rap (1,500 m2) as part of a proposed infill of the east basin at the site. The project will require marine habitat offsetting under a Fisheries Act Authorization. The proposed marine habitat is designed to enhance kelp and juvenile salmonid habitat at the estuary of MacKay Creek.

The proposed project works include:

  • Removal of any large wood/concrete debris in the gravel bed footprint by crane
  • Installation of a 7,500 m2 gravel bed by infilling with approximately 24,000 m3 of 25 to 50 mm gravel
  • Slope protection (3000 m3) of the gravel bed with larger grade rocks (260 mm)
  • Installation of concrete channels in the gravel bed to limit scour from the careen propeller wash
  • Installation of rip-rap slope protection for the east basin infill (1,500 m2)

The proposed habitat offsetting location is east of the project site at the estuary of MacKay Creek. The proposed works to construct the habitat area include:

  • Installation of a rock berm to an elevation of approximately -1 Chart Datum (CD)
  • Place sand fill material behind the rock berm to create elevated pocket beaches
  • Place cobble and small boulders to provide suitable substrate for kelp and salmonids.

Project works are proposed to be conducted by barge using a clamshell bucket and crane. No dredging is proposed as part of this project. Should the proposed project be approved, the project construction phase is anticipated to commence in August 2021 and take up to three months to complete. All marine construction works will take place during the fisheries least risk window for Burrard Inlet.
