Discover the new landform
A dramatic transformation has been taking place at the old Hornsby Quarry. For the past 2 years, fill material from the NorthConnex tunnel project has been placed into the quarry void to raise the ground level and stabilise the steep slopes. The fill works are now complete and NorthConnex are finalising demobilisation from the site while a new landform proposal is being developed.
The new landform has been designed to create a variety of flexible spaces that are suitable for a range of activities.
In the raised floor of the quarry void, a water body is expected to be created, fed by groundwater and rainfall. From the water’s edge, the landform will rise up, broadly forming an amphitheatre, with graded entry from the western and northern sides. Within the eastern face of the quarried walls, the geological formation of a volcanic diatreme will be preserved. Extensive rehabilitation of the surrounding bushland will be undertaken to create a bushland backdrop for the amphitheatre.
Once the earthworks are completed, subject to future design and approvals, varied settings including landscape regeneration, community, cultural and recreation opportunities will be provided in Old Mans Valley, around the old Crusher Plant and in the former fill profile area in south-west corner of the site.
Until landform and future landscape works can be completed, the quarry will remain closed to public access due to risks associated with stability and rock fall hazards. Rehabilitation works will be undertaken firstly to make the site safe and to deliver a landform that will not restrict the possibilities for latter parkland development works, which will include landscape, recreation and amenity embellishments. By anticipated completion in 2023, the old quarry will form a dramatic centrepiece to the new Hornsby Park.
