A flood-friendly park re-creates a resilient landscape in Calgary’s Bow River.

In the summer of 2013, catastrophic flooding in southern Alberta killed five people and forced 100,000 to evacuate. With $6 billion in property damage, it was one of the costliest natural disasters in Canadian history. The swollen Bow River, which flows from glacial headwaters in the Rockies to Calgary, left much of the city’s urban core underwater. The inundated area included St. Patrick’s Island, one of several islands in the downtown stretch of the river, where Barbara Wilks, FASLA, and Mark Johnson, FASLA, had just kicked off construction on a new 31-acre park. A new pedestrian bridge to the island, which was partially built at the time, suffered significant damage. But for the park itself, Wilks and Johnson—the founders of W Architecture and Landscape Architecture and Civitas, respectively—say the floodwaters provided positive reinforcement of their design.
This was not the initial reaction, however, of the folks at the Calgary Municipal Land Corporation (CMLC), their client.
“Our client called and said, ‘Oh, God, you have to get up here; we’re going to have to change the design,’” said Johnson as he, Wilks, and I strolled across the bridge to the completed park on a clear spring day.
“The whole island flooded!’” Wilks recalled members of the CMLC team saying in an urgent and distressed call. “We said, ‘It’s going to be fine; there’s nothing to change. We designed it to flood—this is what’s supposed to happen.’” (more…)
