8. Dereliction of The Wharfs, Railyards & Gasworks Ship freight became more containerised – hence bigger, open yards and deeper docks required (Appleton, Webb and Swanston Docks). Charles Grimes Bridge pushed larger ship docking sites westwards. Modern day transport methods (air & truck) made large shunting yards redundant. Discovery & use of natural gas from Bass Strait saw gasworks closed in 1970. Derelict waterfront area now ripe for “reconnection” with the city.

27. Summary of Whole-Precinct Development Benefits Ability to optimise best sites for purpose (i.e. ensure correct mix of open space, residential, commercial) based on levels of contamination. “Over-kill” remediation – i.e. sustainability considerations can be made. Odours, dust & other construction emissions have less impact. Materials and treatment-space sharing (when appropriate). Services sharing/ staged development.
