Hornsby Council has moved to the next stage of planning for the redevelopment of Old Mans Valley and the Quarry. There is an opportunity for you to make suggestions about how the area should be developed and used.
In November last year STEP held a talk by Dr Ian Percival on the unique volcanic diatreme that has been exposed in the Hornsby Quarry. The Geological Society of Australia and STEP made submissions to the Roads and Maritime Services about the project to use the quarry void to dispose of spoil from the NorthConnex tunnel. But while it appears that the upper two levels of the quarry will escape burial, so far we have seen little reference in any document to the enormous importance of this site as a scientific and educational tool.
The Environmental Impact Statement on Hornsby Quarry was released in August with a closing date for submissions of 4 September 2015. STEP and the Geological Heritage Subcommittee of the NSW Division of the Geological Society of Australia have some concerns.
