2.0      SITE DESCRIPTION

The real property description of the site is Lot 27 on RP 89506, Parish of Weyba and covers
an area of about 1.8 hectares. Attunga Heights and Pif.,tup.:,. Point Cre,eent terminate adjacent
to the southern and western site boundaries respectively. Th site is bounded by residential
properties to the south and west, Halse Lodge (north) and the Viridian Noosa site (east).

Figure 1 shows the proposed development layout o'vet1.3in on the site plan, which includes
ground surface contours and the positions of trees. The base plan for Figure 1 is derived from
JMA Architects Drawing No. 973 DA0001 Rev. B, dated 2 October 2003.

The majority of the site is a moderately to steeply sloping sand dune slope (with an easterly to
north-easterly aspect), intersected by a meandering creek, which runs from the south towards
the north adjacent to the eastern site boundary. The dune slope has a maximum elevation of
about RL 58 m in the south-western corner of the site, with a minimum recorded elevation of
about RL 10 m in the bed of the creek adjacent to the northern boundary. Ground slopes
across the dune typically range between about 20° and 30°, as shown in Photograph 1, with
steeper slopes of up to 40° occurring adjacent to the banks of the creek.

Boulders of diorite up to 800 mm across are exposed in the western bank of the creek in the
northern part of the site. A massive outcrop of diorite is exposed in the bed of the creek
adjacent to the middle of the eastern site boundary. There is also an approximately 1 m deep
outcrop of colluvium (clay and rock), shown in Photograph 2, exposed beneath about 1 m of
sand in the bank of the creek adjacent to the northern site boundary. This outcrop is located
on a relatively sharp bend in the creek below a possible landslip within the dune sand. The
approximate extent of the possible landslip is defined by ground sloping at about 40°, across
which a number of mature trees were observed to have bent trunks indicative of previous
ground movement.
