                             PROPOSED RESIDENTIAL DEVELOPMENT
                             39 PICTURE POINT CRESCENT, NOOSA HEADS

4.7       Vegetation
To the south-eastern corner of the site off Picture Point Crescent, landscaped gardens with small shrubs,
small to medium size trees, and grasses were present. Downslope of the existing residence and within the
subject site, mainly vines and ferns were present with sporadic trees. A medium size tree to the north-
eastern corner of the pool was noted to be leaning slightly. This can be, but is not necessarily always, an
indication of slope instability. On adjacent lots to the east and west, and on ground downslope, moderately
densely planted, larger mature trees were observed.

4.8       Buildings and Other Structures
The existing residence consisted of a split level upper section to the south, ranging from one to two storeys;
then extending over a suspended single level downslope to the north. To the south, the one to two storey
split-level portion of the house featured a mixture of masonry brick and lightweight clad exterior walls. The
suspended portion to the north was timber framed and clad, with steel posts connected to the ground. The
suspended portion of the residence is shown in Text Figure 5.

A pool was present to the south-western corner of the block, which had a concrete shell, and some fill to the
surrounds supported on the downslope side by a masonry block wall. This was estimated to be fully in-
ground to the southern side, extending to about 1 m to 1.5 m out of ground on the downslope side. Along
the northern edge of the pool a suspended timber deck was present (over steel posts), reaching a maximum
height of 3.5 m above ground.

A view of the pool and split-level upper portion to the residence can be seen in Text Figure 4 above.

Based on an external assessment, the structures on the site appeared to be in relatively good structural
condition, with no obvious signs of distress which could easily be attributed to slope instability. It was noted
that an external set of the stairs to the north-western side of the house were slightly tilted, however it was
noted that the posts supporting the stairs were not connected to the concrete footing, which in turn was
founded very close to surface.

A number of small timber retaining walls were present to the north-east, and immediately downslope of, the
existing residence. These ranged to about 1 m height, and were in a poor state of repair, with a number of
rotting and broken rails and posts.
