Fraser River Navigation Channel Maintenance Dredging
On April 13, 2022 a project permit was issued to the Vancouver Fraser Port Authority to conduct annual maintenance dredging of the deep-sea shipping channel in the lower 36 kilometres of the Fraser River, from Sand Heads (kilometre marker 1) to New Westminster (kilometre marker 35), British Columbia. This project is on federal lands and waters managed by the Vancouver Fraser Port Authority.
The project was approved subject to 32 permit conditions the Vancouver Fraser Port Authority must meet to ensure the project does not result in significant adverse environmental effects.
Dredging will be conducted 24 hours per day, 7 days per week during the dredge season, approximately mid to late June to February 28, annually, with the exception of a holiday shut down in December.
About the project
The project comprises annual maintenance dredging of the deep-sea shipping channel in the lower 36 kilometres of the Fraser River, from Sand Heads (kilometre marker ‑1) to New Westminster (kilometre marker 35). The dredging will also include the berths and approaches at DP World Fraser Surrey. The navigation channel will be dredged to the previously approved design width, grade and sub-grades to enable tidal access to DP World-Fraser Surrey Docks for deep-sea vessels with 11.5-metre draughts on a year-round basis. An estimated volume of up to 4 million cubic meters will be removed annually over a five-year period.
Project activities and components include:
- Dredging will be conducted using a trailer suction hopper dredge, cutter-suction dredge, clamshell dredges, scows/barges and supplemental equipment;
- Dredged material will be pumped ashore to upland locations for reuse, disposed of at an approved disposal at sea site, or disposed of at existing in-river disposal sites;
- Dredging will be conducted 24 hours per day, 7 days per week during the dredge season, roughly mid to late June to February 28, annually.
