Maplewood Marine Restoration Project

August 27, 2018

Project status

Permit under review

In August 2018, the Vancouver Fraser Port Authority’s Habitat Enhancement Program (HEP) submitted a project permit application for the Maplewood Marine Restoration Project located immediately south of the Maplewood Flats Conservation Area which is two kilometres east of the Ironworkers Memorial Bridge in the District of North Vancouver, British Columbia in federal waters managed by the Vancouver Fraser Port Authority.

As part of the Project and Environmental Review, the port authority’s Habitat Enhancement Program is required to solicit public feedback on the proposed project, results of technical studies and proposed mitigation measures. The port authority will conduct formal consultation activities with stakeholders as part of the permitting process. The HEP team will undertake the procedural aspects of Aboriginal consultation, as part of the port authority’s permitting process, to ensure the duty to consult has been adequately fulfilled.

Public Consultation

The applicant conducted a public consultation period on the proposed project from September 24 to October 12, 2018. An open house event was held on October 2 at the Corrigan Nature House in North Vancouver.

A consultation summary report and a consideration report of how feedback will be considered is posted below and on the Maplewood Marine Restoration Project website. The port authority will consider all feedback received from the public, stakeholders and Aboriginal groups as part of the Project and Environmental Review of the proposed project.

About the project

The Vancouver Fraser Port Authority’s Habitat Enhancement Program is proposing to develop the Maplewood Marine Restoration Project for use as a fisheries habitat offset for the proposed Centerm Expansion Project, pending approval from Fisheries and Oceans Canada, and to proactively create functioning habitat to provide a balance between a healthy environment and future development that may be required for port operations. The habitat area will include intertidal habitat, subtidal eelgrass habitat, and a rock reef habitat.

The proposed project would convert sections of a deep basin, historically dredged in the 1940’s, into more productive fish habitat by infilling to create shallow intertidal and subtidal habitats in the Northeast Basin. Dredging of the Southwest Channel and creating new rock reef habitat is proposed to improve tidal flushing in the basin and enhanced water quality, nutrient transportation and reduce siltation of marine vegetation. The habitat enhancement is anticipated to facilitate greater suspension and distribution of eggs and larvae of pelagic spawning fish and invertebrates. The proposed Maplewood Marine Restoration Project would result in the conversion of approximately seven hectares of low-value, deep marine habitat, into more productive habitat for fish, birds and other wildlife.

Proposed project activities and components include:

Southwest Channel and rock reef habitat

  • The Southwest Channel will be dredged to improve intertidal flushing and to create an access point for construction barges. It is anticipated approximately 87,000 m3 of material will be dredged from the channel.
  • Approximately 14,000 m3 of rock material will be placed in the dredged Southwest Channel along the base of the channel and along the side slopes of the channel to function as subtidal rock reef habitat and to protect against scour from tidal currents.

Northeast Basin intertidal and subtidal eelgrass habitats

  • Infill the Northeast Basin with approximately 87,000 m3 of dredge material from the Southwest Channel and approximately 95,000 m3 of imported clean fill material to raise the elevation of the existing substrate and create habitat areas.
  • Construction of a rock dyke to contain the fill material by placing approximately 8,500 m3 of appropriately sized rock material.
  • Following construction and habitat stabilization, plant native common eelgrass (Zostera marina) in the Northeast Basin from suitable donor beds.

Construction works are anticipated to be complete by barge using clam-shell dredge and scows or other suitable marine equipment.

Should the proposed project be approved, construction is expected to begin in mid-to-late 2019 and take approximately eight months. The transplantation of the eelgrass will commence the following year.
