Tar Pits & Tanks
Plant Upgrades
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.

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.
