4.3           Geology
Available geological information 1 indicates that the site is near the boundary of Quaternary age, mainly
parabolic dunes comprising ‘quartz sand’ and Holocene age coastal swamp deposits comprising ‘quartz
sand and peaty quartz sand’ (Ref. Text Figure 6).




                                                                          Approx. Site Location

4.4           Subsurface Conditions
Detailed descriptions of the subsurface conditions encountered in the boreholes are provided in the
borehole reports attached in Appendix A, along with definition sheets which describe terms and
abbreviations used on the reports. Subsurface conditions encountered in the boreholes are summarised as
follows:

            Topsoil – comprising loose silty sand to 0.1 m BGL; then
            Natural Sands – comprising loose poorly graded sands to 2 m BGL, then becoming medium
             dense, increasing to dense (or denser) below depths of about 4.5 m to 5.2 m BGL.

Table 1 below, summarises the subsurface profile in each borehole.
