I refer to Council’s Information Request, dated 16 February 2026 in relation to the abovementioned
development.
On behalf of the applicant, Trillium Apperceived Pty Ltd, and in accordance with Section 13 of the DA Rules, we
provide a response to all the issues raised. A response to the item(s) raised in Councils Information Request is
outlined below:
ITEMS 1 & 2 – GEOTECHNICAL CONSIDERATIONS
Provide a site-specific geotechnical assessment prepared by a registered professional engineer (RPEQ)
demonstrating compliance with the PO3, PO12(c) of the Earthworks Code and PO1 of the Landslide Hazard
Overlay Code. The assessment must certify that:
a) the stability of the site, including associated buildings and infrastructure, will be maintained and
operational for the life of the development;
b) the site is not subject to the risk of landslide activity originating from other land, including land above the
site; and
c) development of the site will not increase the risk of landslide activity on other land.
Alternatively, provide a statement by a suitably qualified person (RPEQ) confirming that the proposed works do
not create a risk of landslide in the long term.
RESPONSE
Please refer to the Slope Stability Assessment prepared by Tectonic (Attachment 1), which addresses the above.
