In March 2018, the Okanagan Nation Alliance’s (ONA) Chiefs Executive Council (CEC) gave a directive through Tribal Council Resolution 372 for the Natural Resources department to complete a flood risk assessment, floodplain mapping, and an emergency response approach for the Nation. This includes a need to find solutions on how we may collectively better live with t̓ik̓t (flooding) and have a coordinated approach to emergency response. By developing an Okanagan-basin (including the Similkameen watershed) risk assessment, the Nation can be proactive, and make risk-based decisions regarding their territory and communities, and determine what priority measures can be taken, if possible, to improve safety, reduce, or even negate, the effects of flooding events. The actions identified to achieve this objective are: 1) Forming a flood steering committee, with representation from local governments and Syilx Okanagan Nation member communities, 2) Exploring local perspectives on the impacts of flooding through workshops, impact mapping, storytelling, etc., and 3) Scoring risk on a watershed scale through exposure and hazard mapping, hazard modelling, etc. The project was funded by the National Disaster Mitigation Program (NDMP) and completed from September 2018 to December 2019. Compared to typical risk assessments focused on western science methods, the approach for this project needed to evolve to incorporate Syilx Okanagan perspectives throughout the process. Looking toward the inner layer of the risk assessment approach, mapping is critical to the risk assessment process as it provides a mix of qualitative and quantitative information in a spatial context. This project distinguishes impacts as stemming from qualitative information, whereas consequences stem from quantitative information.
