About the project
Metro Vancouver is proposing to place scour protection consisting of a blended rock riprap apron around the Metro Vancouver Annacis Main #3 sanitary line to prevent erosion. Annacis Main #3 crosses the Annieville Channel on the south arm of the Fraser River between Annacis Island and Surrey, BC.
The proposed apron will be approximately one metre thick and is comprised of two portions (east and west) both tying into one side of riprap placed in 2014. The west portion will upgrade and extend riprap placed in 1995. The east portion will extend the length of the apron toward the east bank. The surface area of the combined apron is approximately 11,523 square metres with an estimated quantity of blended apron material is approximately 9,510 cubic metres. Project works will consist of limited excavation of the Annacis Main #3 and placement of blended rock on the riverbed from a barge using an excavator equipped with a clamshell bucket.
Should the proposed project be approved, construction is expected to take approximately 21 days to complete and is proposed to occur in January to February, 2023.
