Storm drain system succeeds for mega-mall project in salt marshProblem: A new 182-acre mega-mall in British Columbia required a large stormwater management system that could provide corrosion resistance to the salt marsh on which is being built, and structural strength because of the poor deltaic soil conditions in this seismically active region of Canada. Portions of the system would be installed under public roads. The two projects on the peninsula jutting into Boundary Bay are Tsawwassen Mills, an enclosed shopping mall with approximately 1.2 million square feet of retail space, and Tsawwassen Commons, a retail outlet with 555,000 square feet
