Notice of Determination

Port Moody, B.C. – October 8, 2025 – The Vancouver Fraser Port Authority has determined that the proposed Private dock replacement located at 864 and 868 Alderside Road, Port Moody is not likely to cause significant adverse environmental effects.

The determination was based on a consideration of the following factors:

• Impacts on rights of Indigenous peoples
• Indigenous knowledge
• Community knowledge
• Comments received from the public
• Technically and economically feasible mitigation measures

Best efforts were made to consult the following Indigenous groups Kwikwetlem First Nation, Musqueam Indian Band, S'ólh Téméxw Stewardship Alliance, Squamish Nation, and Tsleil-Waututh Nation. Themes raised were:

• Request for the utilization of vibratory pile driving methods and the implementation of bubble curtains
• Inquiry about whether the piles being removed are creosote piles and the mitigations proposed during pile removal
• Inquiry about mitigation measures for marine mammals that may be in the Project area
• Request to relocate sessile or low motility invertebrates in the Project area
• Comment on the cumulative effects of recreational docks
• Request for spill kits

The project was posted to the Canadian Impact Assessment Registry on July 25, 2025, for public comment. No comments were received.

The City of Port Moody and adjacent residents at 860, 872, and 900 Alderside Road, Port Moody were provided an opportunity to comment on the project. Themes raised were:

• Potential Impacts of construction activities to the existing municipal sewer pipe that runs along the shoreline
• Adhering to the City of Port Moody's municipal bylaws and permitting requirement
• Engineering requirements (geotechnical investigation, monitoring, etc.)
• Environmental concerns and feedback on the intertidal and subtidal assessment, including the applicability of the Heritage Conservation Act, project scope, and environmental mitigations
• Comments around the Port Authority's real estate licensing process

Mitigation measures and/or permit conditions taken into account in making the determination include:

• A spill prevention, containment and clean-up plan will be developed for the project, be available in the immediate working area, and project personnel will be trained on spill prevention, containment, and clean-up
• A professional engineer will design the project
• Construction debris and waste materials will be collected in the immediate working area and disposed of at an appropriately licensed facility
• Construction equipment will be environmentally clean and properly maintained to prevent spills, invasive species, and noxious weeds
• The works will not deposit a deleterious substance in water inhabited by fish, or affect fish or fish habitat in a manner contrary to the Fisheries Act
• The physical activities will be conducted in a manner that avoids increasing sedimentation of foreshore and nearshore areas and induced turbidity of local waters
• Activities involving the use of concrete, cement, or other lime-containing construction materials will be conducted so that the materials do not enter the aquatic environment
• Activities will not disturb the seabed outside the Project site, and there will be no excavation activities within the project's footprint
• There will be no in-water works during the fisheries sensitive period from March 1 to August 15, inclusive

The Vancouver Fraser Port Authority is satisfied that the carrying out of the project is not likely to cause significant adverse environmental effects.
