Flooding poses a significant challenge for coastal cities worldwide, and recent interest has focused on implementing nature-based infrastructure projects for coastal flood risk management. However, a lack of monitoring data and technical guidance hampers their adoption. This study addresses this gap by providing wave transmission coefficients (Kt) for four edge treatment features at the Living Dike pilot project in Boundary Bay, British Columbia. Near-shore wave data from RBR pressure sensors deployed in cross-shore transects at the project site are supplemented by biweekly field observations assessing treatment stability and weathering. The four edge treatment features provided statistically significant reductions in wave height, with the brushwood dam exhibiting the lowest wave transmission coefficients at values of relative freeboard to significant wave height below -2 (0.25 < Kt < 0.75). These findings offer valuable insights into the use of nature-based infrastructure projects for coastal flood risk management strategies.
