4.2       Topography
During our site walk-over, topographic features specific to the site were noted, and ground slopes were
recorded using a hand-held clinometer. As illustrated in Text Figure 8 overleaf, the site is located just
beyond the initial crest of a high dune at Sunshine Beach. The stoss face of the dune is generally eastward
facing at the site location.

Ground around the existing residence was terraced with generally relatively level benches supported by
blockwork walls up to about 3 m height that were incorporated within the existing residence and garage.
Beyond the residence, in the northern half of the site, a small relatively level grassed area had been created
by historic cut to fill earthworks with a downslope batter of up to 35°. The southern half of the site naturally
sloped to the east at about 22°. At approximately the eastern boundary and beyond the dune fell towards
the beach at about 17°. At the toe of the high dune a shallow dune slack was noted before the small frontal
dune of about 1 m height. The beach dropped down from about RL 4 m AHD at the toe of the frontal dune to
the shoreline (around RL 0 m AHD).
Around 200 m south of the subject site a creek line joins the beach from the west. The creek had a
consistent, but relatively small flow at the time of our fieldwork; discharging directly into the ocean.

A selection of the geomorphological features described above are denoted on Text Figures 4 to 7 on the
preceding pages.
