As illustrated in Text Figure 3, the site is located on land around RL 10 m to 15 m AHD between the
foredunes which run parallel to Sunshine Beach and the higher sand hills to the west (which range up to
about RL 50 m AHD). Natural watercourses flow from the sand hills to the beach about 100 m to the north
and south of the site.

Surface gradients around the existing house are less than 10° (<15%) in an easterly direction, with relatively
flat grassed areas separated from the house/pool terrace by a short slope with a gradient of 15° to 20° (26%
to 36%). The foredune located about 20 m to 30 m east of the existing structures slopes at about 30° (58%)
                       D


down towards the beach.

At the time of investigation the site was occupied by an existing two storey residence of masonry (lower) and
light-weight (upper) construction, with a tiled roof. The house is surrounded by garden beds and areas of
lawn, with a paved driveway and parking area at the front (leading from Webb Road) and in-ground pool to
the rear. Scattered trees including mostly palms and pandanus are located around the house.

No indications of erosion or slope instability were observed. The foredune to the east of the house was
relatively well vegetated and did not show any signs of recent scarping.

Refer to Text Figures 4 to 7 on the following pages for photographs showing site conditions at the time of
investigation.
