Appendix 18.18 – Underwater Acoustic Modelling Report
Predictive modelling of underwater noise from pile driving to inform the environmental impact assessment for the construction of a four-lane bridge across the Fraser River to connect the cities of Surrey and New Westminster, British Columbia. Pile driving noise is transmitted from the pipe pile through river sediments and sheet pile wall, and into the water. Sound levels and ranges to acoustic thresholds in water that may result in injury to valued ecosystem components such as fish (e.g. sturgeon and Pacific salmon) were reported.
