Municipal perspectives on managed retreat and flood mitigation: A case analysis of Merritt, Canada after the 2021 British Columbia flood disaster

In response to the catastrophic flooding that occurred in British Columbia, Canada in November 2021, the City of Merritt is facing a difficult decision about whether to rebuild or not. The developing situation in Merritt provided a unique opportunity to explore the different types of adaptations (i.e., investments in climate resilient infrastructure, rebuilding, construction of structural mitigation, zoning, and buyouts) considered by policymakers in advance of official municipal decisions. Through qualitative mixed methods (e.g., interviews, open houses, town council meetings), the study explored preliminary discussions among decision makers surrounding long term risk reduction options including rebuild and retreat strategies, perceptions of flood risk, recovery challenges faced by small-scale municipalities, the development of the community’s flood mitigation plan, and recommendations for post-disaster transitional supports. The results indicated that communities in the post-disaster recovery phase are considering the use of buyouts as a risk reduction tool amongst broader flood mitigation strategies, however policy constraints and a lack of funding are impeding the implementation of a flood mitigation plan that includes buyouts. The findings suggest that decisions about post disaster recovery are often independent of broader municipal climate change adaptation plans instead focusing on short-term risk reduction mechanisms. Additionally, transitional supports including interim housing need to be accounted for in recovery planning. Governments in Canada can capitalize on the policy windows during the post-disaster recovery stage and learn from municipalities about the challenges and opportunities in the design and implementation of flood mitigation plans that can help to improve disaster policy.
