B.C. Mudslides Expose Decades of Short-Sighted Governance and Climate Neglect
On March 19, a dramatic helicopter rescue operation evacuated eight people, two dogs, and a cat from Pipeline Road in Coquitlam after a devastating mudslide completely isolated their neighborhood. The landslide severed power to 5,000 customers and buried the only access route to Metro Vancouver's largest drinking-water reservoir, marking the third failure of that specific hillside in just ten years.
The Immediate Trigger and Deeper Causes
The immediate cause was an atmospheric river that dumped over 300 millimeters of rain on the mountains north of Vancouver. However, treating this as merely a weather event overlooks the deeper systemic issues that have been accumulating for decades. The real problem lies in the compounding costs of approving development in known hazard zones, chronic underinvestment in mitigation infrastructure, and policy-making that prioritizes election cycles over long-term physical realities.
This is not just a weather story—it is fundamentally an economic one. The 2021 atmospheric river event caused up to $7 billion in damage, closing every major highway connecting Vancouver to the rest of Canada, disrupting the Port of Vancouver's supply chain for nine consecutive days, and forcing the evacuation of all 7,000 residents of Merritt.
Failed Mitigation Efforts and Funding Shortfalls
Despite Ottawa creating a $2-billion disaster-mitigation fund in 2018 and adding $1.375 billion after the 2021 floods, and Victoria committing $2.1 billion to recovery from floods and wildfires, critical applications for flood-mitigation funding from Abbotsford, Merritt, and Princeton were denied. The province developed a comprehensive flood strategy in 2024, but the 2025 budget failed to allocate any funding to implement it. Consequently, when atmospheric rivers returned predictably in March, the strategy remained nothing more than a document on paper.
The Hazardous Development Feedback Loop
This situation creates a dangerous feedback loop. From the Vancouver waterfront, the view north reveals numerous properties built on slopes that geotechnical engineers have known for decades are prone to failure under sustained rainfall. Hazardous housing develops gradually through incremental, short-horizon approvals, where individual permits accumulate into massive liabilities that materialize long after the approving politicians have left office.
Historical precedents underscore this pattern. The 2005 Berkley Escarpment landslide in North Vancouver killed one woman and destroyed two homes, despite recorded debris flows on the same slope in 1979 and subsequent residential permits issued at its base over 26 years. Similar tragedies occurred in October 2024 when a Port Moody teacher died after a debris flow swept away her home near Minnekhada Regional Park, and again with the Coquitlam families in March.
Insurance Gaps and Uninsurable Risks
Compounding the crisis, displaced residents are discovering that no insurer in Canada covers landslide damage, as confirmed by the Insurance Bureau of Canada. This leaves communities facing real physical risks with uninsurable financial losses, yet civic approvals for development in these hazardous areas continue unabated.
To address these challenges, experts argue that British Columbia must move beyond piecemeal approaches. Hazard maps must be updated to reflect future climate projections, and land-use approvals in slope-hazard areas should trigger rigorous geotechnical assessments to prevent further tragedies and economic losses.
