ADDRESSING AFFORDABLE HOUSING’S HIDDEN UTILITY COSTS: “When you go down four, five and six levels of underground excavation for high-rise building foundations, you are intercepting and dewatering the groundwater resource,” stated Robert Hicks, career engineer-planner in local government in the Metro Vancouver region of British Columbia
“Land use intensification and redevelopment – where does that water go? I see the answer having two faces for RISK and LIABILITY. You are creating a drainage demand by preventing rainwater from reaching building foundations or removing groundwater at depth. But the other face is the lost opportunity because the water resource is not being managed in either a coordinated or holistic manner. Creating a drainage demand is the more immediate consequence of land use intensification. The loss of groundwater as an option for water supply is a future reckoning,” stated Robert Hicks.
