The Regional District of East Kootenay (RDEK) is in the fieldwork stages of its Regional Flood and Steep Creek Risk Prioritization Project. BGC Engineering was in charge of consultations, conducting site visits between Nov. 1 and Nov. 3.
Due to the uncertain and everchanging weather patterns caused by climate change, increasing precipitation patterns have impacted the frequency and magnitude of flooding. Fiona Dercole, RDEK Protective Services Manager says, “this project will modernize our understanding of flood and steep creek risks across the region and inform the region’s Hazard, Risk and Vulnerability Analysis, which forms the foundation of the East Kootenay Emergency Management Plan.”
The site visits in the Columbia Valley focused on areas where steep creeks had the highest potential to produce debris flooding. This was determined based on past events, along with terrain mapping tools and a terrain review using LiDAR.
“The geotechnical engineering qualified professionals that conducted the site visits were looking primarily at the sediment discharged by the creeks and at the character of the creeks to determine if the creeks had...continued.
