        Table 2: Stability Risk Levels
          Risk Level                   Example Implications(1)

          VH        Very High Risk     Unacceptable without treatment. Extensive detailed investigation and research, planning and
                                       implementation of treatment options essential to reduce risk to Low; may be too expensive and
                                       not practical. Work likely to cost more than value of property.

          H         High Risk          Unacceptable without treatment. Detailed investigation, planning and implementation of
                                       treatment options required to reduce risk to Low. Work would cost a substantial sum in relation
                                       to the value of the property.

          M         Moderate Risk      May be tolerated in certain circumstances (subject to regulators’ approval) but requires
                                       investigation, planning and implementation of treatment options to reduce risk to Low.
                                       Treatment options to reduce to Low risk should be implemented as soon as practicable.

          L         Low Risk           Usually acceptable to regulators. Where treatment has been required to reduce the risk to this
                                       level, ongoing maintenance required.

          VL        Very Low Risk      Acceptable. Manage by normal slope maintenance procedures.

        Note: (1) The implications for a particular situation are to be determined by all parties to the risk assessment and may depend
        on the nature of the property at risk; these are only given as a general guide.

        Considering the existing site conditions (Ref. Section 2), and subject to the implementation of
        recommendations given below, it is assessed that there should be a Low Risk of global slope instability
        affecting the proposed development. Regulators (NC) normally require that a Very Low or Low Risk of
        landslide affecting the property must be demonstrated to enable development approval.
        Summarised in Table 3 overleaf is our qualitative assessment of landslide risk for the development site. A
        summary of qualitative terminology for use in assessing risk to property is attached (taken from AGS
        2007).
