Drawings have been prepared for the preliminary bulk earthworks based on the amended
Architectural plans. These plans are included in Attachment 19 and reflect the stabilised
surface level.

Due to the conceptual nature of a Material Change of Use of Premises application, the
request for this level of detail is considered excessive. This information will be submitted as
part of the Operational Works application to Council.

There appears to be cuts of up to 6 metres below natural surface level. Provide details as to
how this level of cut complies with Overall Outcome 14.136.2 of the Earthworks Code.

As detailed in Item 54, due to the lightweight construction of the Villa units and reduction in
basement parking within the larger buildings, the development does not propose significant
cuts across the site. Generally, the proposed level of cut does not exceed 2 metres, with only
one cut of 6 metres are proposed. This cut is located at the rear of the compactus unit
adjacent to Building V.

Overall Outcome 14.136.2 of the Earthworks Code seeks:

a) To ensure that earthworks do not unreasonably impact on the natural
environment or other properties with regard to-
i land stability (including differential settlement or expansion in reactive
soils;
ii. contamination of land:
iii. flooding and drainage;
iv. groundwater, watercourses and wetlands;
v. loss of native remnant or regrowth vegetation; and
b) Earthworks are designed and constructed to be structurally sound.

It is considered that this area to the rear of the Central Facilities Building will not
unreasonably impact on the natural environment or other properties as it is located:-

+ towards the centre of the site;

+ clear of the contaminated cell (which is proposed to be removed prior to
earthworks being undertaken);

+ in an area not anticipated to experience flooding and/or drainage concerns;
* — clear of the creek buffer area;
+ within an area already cleared for development.

All works associated with this area will be structurally sound, with further detail to be
submitted as part of the Operational Works application to Council.
