How will groundwater and the potential for flooding be addressed through the design process?
A. Drainage of stormwater and any groundwater from the underpass will require pumping as the underpass road level will be lower than the existing stormwater drains. The drainage system has been designed to deal with high rainfall conditions and there will be backups in case of mechanical or electrical problems. The Project Team will ensure that the design meets the requirements of the Environmental Protection Authority, Department for Water, Land and Biodiversity Conservation and the Adelaide and Mount Lofty Ranges Natural Resources Management Board.
