    3.3 Regional Geology
Based upon the 1:100,000 Gympie Special Geological Map (Department of Mines and Energy,
Queensland, 1999), the site is underlain by beach sand deposits of the Quaternary Age (1.8
Mya to present) described as Pleistocene dune sand (quartz sand) and Holocene beach ridge
and berm (quartz sand).

    3.4 Published Stability Data
The searchable Geoscience Australia Landslide Database (2018) was reviewed. No recorded
landslides were located in the vicinity of the site (2km radius).

    3.5 Site Factors
The principal site features were:-

          The site is located on the eastern side of a low hill, with slopes falling relatively steeply
           towards the east which roughly cross the north eastern end of the site diagonally (refer
           Plate E1, Appendix E).
          An existing partially two storey timber residence is located towards the south western
           end of the site, elevated above the natural slope (refer Plate 1, Appendix E). The
           columns for the structure appear to be founding on concrete piers.
          A timber sleeper retaining wall exists along the western side of the residence supporting
           the western sub ground floor level wall (refer Plate 2, Appendix E).
          Park Crescent appears to be situated near the top of the natural slope with some filling
           likely undertaken at the western side (upper part) of the site as part of the road
           construction.
