Fraser River Navigation Channel Maintenance Dredging

The proposed 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.  

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.
