          The earthworks should be designed and constructed in accordance with sound and
           proper engineering principles.
          Likewise, the future construction should be planned designed and constructed in
           accordance with sound and proper engineering principles, and more specifically in
           accordance with good hillside construction practices (refer Appendix D).
          All construction works to be carried out in accordance with the recommendations of
           this report.
          The access and drainage infrastructure must be properly and effectively maintained,
           to ensure that all stormwater is intercepted and controlled. This requirement extends
           to all owners and occupiers being aware that ongoing maintenance of the site
           drainage is essential for continued site stability.

The following recommendations should be adopted:-
          All engineering works should follow the appropriate codes i.e.
                o     Footings for buildings - AS.2870 'Residential Slabs and Footings'.
                o     Retaining structures - AS4678 ‘Earth Retaining Structures’.
          Vegetation - where possible the prompt re-establishment of ground cover should be
           undertaken to reduce the risk of surface scour during and following rainfall. Where
           not possible, other forms of surface protection should be adopted.

           6.4.3      Specific Recommendations for the Proposed Structure

The following recommendations are in addition to the above:-

Structural Design

Structure must be adequately structurally designed for the site, and should include lateral
bracing parallel to the slope of the site.

Footings

Footings must be supported on deep foundations (where applicable) and found into the
dense sands as per Section 5.4.2.

Filling

No filling should be carried out on this site.

Water

We recommend that the discharge of waste and storm water be directed into approved
council collection systems and should not be disposed of on site.
