Hydrogeology is a fickle mistress, or something to that effect.
Groundwater conditions vary across the City and dealing with the upward groundwater pressures you can get under a parking structure is not easy or cheap. So most only go as deep as they feel will safely keep them above the highest groundwater level.
Lots of hydrogeologic engineering went into the Hydro parking structure and problems were still encountered. Wawanesa is close enough that those lessons would have been applied to their structure.
