Water Street was commissioned by Copper Mountain Mining Corporation to investigate possible causes of erosion leading to a slide adjacent to the Similkameen River that occurred in 2018 and 2019.

Water Street carried out a review of historical aerial imagery and a site visit to review the conditions at the location of the slide and assess the geomorphology of the Similkameen River through the area of interest. A technical memorandum was prepared to present the findings of the assessment.
