The proposed project

Envirowest Consultants Inc. on behalf of Metro Vancouver's Greater Vancouver Sewerage and Drainage District is proposing to construct a 250 square metre marsh channel, marsh bench and intertidal mudflat on the north side of Annacis Island adjacent to the 1400 Block of Cliveden Avenue, Delta, BC as part of a Department of Fisheries and Oceans Canada Fisheries Act Authorization habitat offsetting project.

The Project will consist of the following

  • Removal of invasive species and two black cottonwood trees
  • Removal of a grounded derelict wooden barge and construction of a marsh channel
  • Construction of a marsh bench and intertidal mudflat
  • Planting of native sedge, tree and shrub species

Project works within the Vancouver Fraser Port Authority's jurisdiction are limited to the marsh bench and intertidal mudflat construction and planting.
