  flows to the east, into a dam. The northern portion of the site drains in a northerly direction towards a large
  dam, with the southern portion of the site draining towards the south easter corner of lot 394.

  Slope typically range from 1-15% for the majority of site.

          SITE HYDROLOGY

  It is likely that the majority of rainfall on the site is absorbed into the soil. However, during extended periods
  of heavy rainfall, it is anticipated that excess rainfall not adsorbed into the soil profile will move to the
  lower areas of topographical relief via sheet flow. Excess rainfall from the northern portion of the allotment
  would likely migrate to the dam located within the northern portion of Lot 650. While the central portion of
  the site would drain towards the central drainage line, into the central dam, before flowing into the eastern
  portion of lot 394. Excess rainfall from the southern portion of the site will like flow into the eastern portion
  of lot 394.

          GEOLOGY

  The geology for the site and surrounding area is identified as arenite-mudstone, with Stratified unit
  (including volcanic and metamorphic).

          SUB-SURFACE CONDITIONS

  A preliminary geotechnical investigation for effluent disposal assessment was carried out within the
  subject development area on the 23rd March 2022. The investigation was carried out in accordance with
  the procedures outlined in AS1547:2012. A total of 4 boreholes were advanced across the site using a
  4WD mounted Auger. The results of the geotechnical assessment are provided in Table 1 below.

  The Borehole locations are shown in Appendix B of this report. A copy of the soil profile logs has been
  included as Appendix C.

  The soil profile across the proposed treated effluent irrigation areas were relatively uniform consisting of
  moderately/massively structured Silty Clay (Category 4/5) underlain by massively structured Silty Clay
  (Category 6).
