Westleigh Park

Westleigh, NSW

Transforming Hornsby Quarry into a Centennial Park-style parkland

TTW and Environmental Partnership have been engaged by Hornsby Shire Council to assist in the delivery of what will become a significant recreational and sports precinct for both the local and greater Sydney community.

Covering 34 hectares of land, the Centennial Park of the north will house multi-use sporting fields adapted for various organised sports and provide multiple amenities, grandstands and maintenance sheds. The work scope also includes new access roads and car parking, including a new link between Quarter Sessions Road and Sefton Road, play facilities for active and passive recreation, including mountain bike and walking trails.

Accordingly, the draft master plan proposes three sports facility platforms designed to work within the constraints of the existing bushland vegetation and the future provision of improved road access: Athletic track and support facilities, central multi-purpose and the southern multi-proposal natural turf sportsfield platform.

Our purpose is to identify an alternative network that relocates trails to the edges and away from high-value biodiversity in terms of mountain bike trails and bushwalking tracks. The aim is to reduce critically endangered ecological communities and threatened species while allowing mountain biking and bushwalking on site.

Once the first stage of this project is finished, not only a connection between Westleigh Park and Hornsby Park will be open, but it will also include two points of entry and exit, which will spread the peak traffic flow and provide greater public safety. The extension to Sefton Road will also enhance traffic flow from Westleigh to the north.

Featuring many sustainability initiatives, this project will also have opportunities for water sensitive urban design and revegetation of the existing surrounding bushland. The park will be built on a post landfill site, addressing a range of challenges, including its landfill history and context within an Endangered Ecological Community (EEC).
