The November 2021 British Columbia, Canada Storm: Observations and Lessons Learned From Assessing Pipeline Infrastructure Subject to Natural Disasters Available to Purchase

In mid-November 2021, southwest British Columbia (BC), Canada was struck by a significant storm system dropping record rainfall over a 2-day period. This storm manifested resulted in significant impact and damage to critical infrastructure including bridges, highways, railways and pipelines, as well as leading to flooding that cut-off the most populated region of BC from the rest of Canada and an estimated rebuilding cost of $10 billion Cdn. This paper provides a background on the storm and the conditions that preceded it, remote sensing data that was gathered during and immediately following the event, mitigations that were implemented, and learnings needed to return the impacted pipelines into service.
