                 9       SLOPE RISK ASSESSMENT
                 “Risk is defined in the Australian Geomechanics Society publications as a measure of the
                 probability and severity of an adverse effect to health, property or environment. Risk is often
                 estimated by the product of numerical probability and consequences; however, a more general
                 interpretation involves a comparison of the probability and consequences in a non‐product
                 form. To carry out a full risk assessment of the site would require a full understanding of the
                 type of structure proposed and the associated earthworks along with the likely consequences
                 should failure occur.
                 The site was assessed in terms of “Landslip Risk Management Concepts and Guidelines”
                 published by The Australian Geomechanics Society.

                         RISK LEVEL                                      EXAMPLE IMPLICATIONS
                      VH  VERY HIGH RISK                 Extensive detailed investigation and research, planning and
                                                         implementation of treatment options essential to reduce risk
                                                         to acceptable levels; may be too expensive and not practical
                        H              HIGH RISK           Detailed investigation, planning and implementation of
                                                        treatment options required to reduce risk to acceptable levels

                       M       MODERATE RISK          Tolerable, provided treatment plan is implemented to maintain or
                                                                 reduce risks. May be accepted. May require
                                                              investigation and planning of treatment options.
                        L              LOW RISK         Usually accepted. Treatment requirements and responsibility
                                                                  to be defined to maintain or reduce risk.
                       VL       VERY LOW RISK               Acceptable. Manage by normal slope maintenance
                                                                                 procedures.


                 It is our opinion, based on Appendix C of Australian Geomechanics Society, “Practice Note
                 Guidelines for Landslide Risk Management 2007”, that if development is managed in
                 accordance with the recommendations in this report and the geotechnical development
                 constraints presented are strictly followed, the site can be developed with a MODERATE
                 RISK of damage to persons or property prior to construction of the retaining wall and a LOW
                 RISK of damage to persons property once the retaining wall has been constructed.
