6.2 TOPOGRAPHY

The ABGMA landscape is deceptively variably - with rolling hills and undulating valleys, there is a diversity of spaces both high and low.

In principle, the Master Plan design seeks to retain the overall topographical character of the site and allow for minimal disturbance in the re-design. For instance, the high point and ridgelines will largely be untouched and unchanged - recognising that these are significant cultural markers for the site for First Nations peoples, and indeed the wider community.

The key change to the topography of the site occurs at the core - with the two existing lakes seeking to be formed into one generous lake. This will involve some associated cut and fill to the landform in this area, however endangered ecological community and constrained site assets will remain unaffected by these works.
