We are redeveloping the abandoned Hornsby Quarry and adjacent Old Mans Valley, approximately 1km west of the Hornsby town centre, and transforming the site into open space for community recreation and entertainment. The area features approximately 60 hectares of bushland and open space and is home to several features of Aboriginal significance, historical and community interest, including the Hornsby Diatreme Area, early settler relics, the State Heritage listed Old Mans Valley (Higgins Family) Cemetery and remnant buildings of the quarry crusher plant.

• The Hornsby Quarry Rehabilitation Works Development Application (DA/101/2019) was approved by the Sydney North Regional Planning panel on 4 November 2020. The approved works have now been completed.
• On 8 March 2023, HSC resolved to undertake Stage 1 Embellishment Works which are nearing completion.
• HSC are now working to deliver Circulation Works which were approved earlier this year.
• Stage 2 works will build upon the above works across the park and are a vital next step in the path to realising the Master Plan. The proposed works in Old Mans Valley (OMV) will start to fill in some of the remaining pieces of the park.
• This stage will develop the park's primary entry and orientation space, strengthen connections back to Hornsby, and balance the recreational needs of future visitors.

The Hornsby Park Embellishments – Stage 2 REF assesses possible impacts the project will have on the environment and details steps to be carried out to avoid, minimise or mitigate those impacts.

The assessment considers:

• Air and water impacts
• Soil and stability impacts
• Noise and vibration impacts
• Fauna and flora impacts
• Ecological impacts
• Threatened species considerations
• Community and natural resources
• Social and economic factors
• Heritage, aesthetic and cultural impacts
• Landuse impacts
• Transportation impacts

It also includes proposed environmental safeguards, disposal of waste and materials recommendations, monitoring and public safety factors.

As shown by the plan in Appendix D, Attachment C, the proposal is delivered in areas assessed with previous REFs. Direct impacts to vegetation are not expected.

There is some potential for minor short-term impacts to the physical environment to occur, including an increase in noise and vibration and a decrease in air quality due to increased dust during construction.

Mitigation measures will be put in place to avoid or minimise any potential environmental impacts that are associated with the proposal.

The assessment considers that impacts to environmental values are manageable and not significant. As a result, the proposal is unlikely to significantly affect the environment, and an EIS or Species Impact Statement is not required.
