Blacktown Showground

Blacktown City Council / Blacktown, Australia

As part of the Blacktown 2025 Vision, Blacktown City Council appointed McGregor Coxall as lead consultant to redevelop the Master Pan for the Blacktown Showground to transform the site into a vibrant recreation precinct. Following adoption of the masterplan, the team was engaged to undertake Landscape Architecture services and documentation for the community garden, wetland, pedestrian linkages and elements of the play spaces.

The design seamlessly integrates a site wide water treatment strategy, collecting water that flows from the Blacktown CBD and treating it in the Showground. Some of the water is recycled, reducing demand on potable water whilst the wetlands provide good quality aquatic habitat. The treatment of water through raingardens, bio retention basins and the wetland effectively cleans stormwater runoff and protects the ecological health of downstream receiving waters. The use of on-site detention, water retention and storage also addresses runoff, making the site capable of handling high flows to mitigate flood during heavy rain. The showground is now a valuable community asset, home to a diverse range of aquatic ecology, local birds and has become a well used community park for adults and children.
