FIGURE 2: OVERVIEW OF SITE, LOOKING NORTH-WEST
At the time of investigation, there was no evidence of distress in the existing residence or retaining walls that
would normally be attributed to slope instability. In addition, the existing slope (ie. sand dune) at the site did
not show any signs of disturbed ground, tension cracks or other signs which are normally associated with slope
instability.
The regional geology overlay from available geology sources is given in Figure 3. The mapping indicates that
the site is underlain by by Pleistocene aged dune sand. The subsurface conditions encountered in the bores
comprised sand, inferred to be Aeolian deposits (ie. wind deposited sand dunes).
