Frequently Asked Questions

Hornsby Park including Old Man’s Valley and the former Hornsby quarry site will be transformed from a degraded site to the region’s premier new parkland.

Council is calling for ideas from our community about what sort of park it may be.

Our initial engagement campaign, ‘Plan Your Parkland’ called for your high-level ideas on the activities, uses and attractions you’d like to see once the quarry site has been transformed. The active 6 week engagement period has now closed and we are currently preparing an Outcomes report on what we’ve heard.

As part of generating our report, we will be showcasing the design ideas collected through ‘Plan Your Parkland’ at two community information and feedback sessions in Hornsby Mall on:

  • Thursday 18 May, 11 am – 2 pm
  • Saturday 20 May, 10.30 am – 3 pm

The website will also be updated to display these ideas.

A full list of engagement activities can be found here.

The development of Hornsby Park is a major project that will take many years to fully realise. Council will further consult with the community right up until the park opens in 2023. Stay up to date with the conversation via our website and various social media pages.

Council has established a Community Deliberative Forum. An important role of the Community Deliberative Forum is to anchor the engagement process in the opinions of the community. This group of randomly selected community members will review the ideas put forward by the broader community and help Council select the best ideas that can be developed into a masterplan for the site. This group will provide local knowledge, skills and input to the project and help to ensure that Hornsby Park is designed, owned, used and loved by residents.

Council has appointed consultants who will appraise all submissions received and prepare an independent report that summarises the findings. This report will be reviewed by the Community Deliberative Forum and made available to the broader community when finalised.

Council will consider the findings of this report when preparing the detailed park plans.

Stage 1 – Northconnex Quarry filling
Excavated material from the NorthConnex tunnel project will be used to partially fill the old quarry void and begin its transformation to a parkland. This will occur between 2017 and 2019.

Stage 2 – rehabilitation works
Council will cut back the slopes on the northern and southern sides of the quarry and modify land around the crusher plant and Old Mans Valley to create the new parkland. This will occur between 2019 and 2021.

Stage 3 – park development
During this stage the final development of parkland will take place. This will include development of infrastructure such as roads, trails, water and electrical services and park facilities. This will occur between 2021 and 2023.

  • Large open space asset close to the CBD
  • Rehabilitation of a degraded site
  • Interesting geology
  • Valuable heritage and natural resources
  • Variety of spaces that can provide for formal and informal recreation

The Old Mans Valley Cemetery on the south eastern side of the quarry is State heritage-listed.

The following elements are listed as locally significant heritage items: The Crown land portion of Hornsby Park, a stone receptacle and cool room, the Depression Steps and the Hornsby Quarry Diatreme.

The parklands also contain Endangered Ecological Communities.

Council has allocated approximately $52 million to rehabilitate and landscape the quarry void and develop a range of recreation facilities on the adjoining Old Mans Valley site. A significant proportion of this money is coming from developer contributions.

NorthConnex is responsible for these works and can be contacted via the following methods:

CSR Ltd owned Hornsby Quarry which was zoned Open Space A. Under the Hornsby Shire Local Environment Plan 1994 (LEP), owners of land which was zoned Open Space A could require that the taxpayer acquire the land. In accordance with its rights under the LEP, on 22 March 2001 CSR Ltd (CSR) notified the Hornsby Shire Council that it required the Council to acquire the quarry.

Council initially resisted the request; but after an action was taken by CSR in the Land and Environment Court, a notice pursuant to s 19 of the Land Acquisition (Just Terms Compensation) Act 1991 (NSW) was published in the Gazette. The effect of the notice was that the land was vested in Council. Under s 37 of that Act, CSR became entitled to be paid compensation.

Council paid to CSR a total of $26,508,771.28 by way of compensation, however Council was able to recoup over $6M. Subsequent to this decision by the Land and Environment Court the Land Acquisition (Just Terms Compensation) Act 1991 (NSW) has been changed so that Council’s cannot be pursued under this legislation.

The quarry commenced operation more than 100 years ago. The remediation requirements were considered by the Auditor General when they valued the land and determined the price that Council must pay for the acquisition.  The Auditor General’s determination did not require CSR to remediate. Council has appealed this decision and other matters associated with the acquisition of this land. Council has received some compensation and these funds are being directed towards the current work which is focused on restoring the land and creating a park.

To place the fill into the quarry void, it has been necessary for Northconnex to construct a haul road from Peats Ferry Road down to the flat open area west of Hornsby TAFE known as Old Mans Valley.  The road has been constructed in very steep terrain to accommodate large vehicles and will continue to serve as a valuable second park access once the park construction is completed in 2023. Northconnex will also install and operate a series of conveyor belts that will take their fill material from Old Mans Valley into the quarry  and spread the fill in layers across the quarry floor.  Council considers that it is reasonable to contribute $7.3M towards the Northconnex fill project for the benefit of gaining a future second park entry, new landform in Old Mans Valley, and new landform within the quarry void.
