Mainland Construction Materials ULC | Retaining wall replacement
In August 2020, a permit was issued to Mainland Construction Materials ULC (the Applicant) to replace their failing rip-rap apron and creosote pile foreshore retaining wall with a steel sheetpile retaining wall at their site. The site is located at 220 Edworthy Way in New Westminster, British Columbia, on lands managed by the Vancouver Fraser Port Authority.
The project was approved subject to 43 permit conditions that the Applicant must meet to ensure the project does not result in significant adverse environmental effects.
The works are proposed to commence in fall 2020 and will take approximately 3 weeks to complete.
About the project
The proposed works will protect the Mainland Construction Materials ULC site from erosion and reduce the risk of rip rap being a hazard to their barge operations. Approximately 72 cubic metres and 18 creosote piles will be removed. Approximately 40 linear metres of steel sheetpile will be installed along the Fraser River’s north banks. The space between the new sheetpile wall and the existing shoreline will be backfilled with approximately 792 cubic metres of 20mm or 40mm clear drain rock. A 10 inch perforated drain pipe will be bedded in the drain rocks to prevent flooding. Piles will be removed and installed with a vibratory hammer. Removal and installation activities will be from shore using a long-reaching excavator.
