Spring Cove Subdivision involved the development of the old St Patrick’s Catholic Church land on the harbour side of Manly’s Eastern Hill. The works involved a significant site clearing exercise, whilst protecting the native wildlife (endangered bandicoots), and preventing sedimentation leaving the site and entering Colin Beach where the endangered fairy penguins nest. The final outcome was a subdivision with all new infrastructure installed, concrete roads and significant site structures including boardwalks, look-outs, bridges and retaining walls. The stormwater design utilized the use of landscaped bioswails to capture water prior to it entering the stormwater system. The contract also involved the bulk and detailed excavation to enable the construction of townhouses, apartments and houses on the estate.
