Infrastructure of Vulnerability, or, How the Fraser Valley Flooded Twice

Abstract

In November and December of 2021, the Fraser Valley in southwest British Columbia suffered extreme flooding due to an atmospheric river. Although the event was attributed to climate change, I suggest that the recent floods must be understood through the historical geography of flood control infrastructure in the valley, particularly dikes. In this article, I trace the development of these infrastructures from the beginning of colonisation to the completion of the first state-managed diking system in the early 20^th century. I argue that at the same time as dikes secured land for settler farmers, they exposed Indigenous peoples to new hazards—ironically including floods—and multiplied the damage of future flood events. Building on geographic literature demonstrating the participation of dike infrastructure in racialised capital accumulation and settler colonialism, I highlight the way that dikes have abetted these projects through the uneven spatial production of vulnerability.
