                  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 proposed development works, it is assessed that
                there would be a Low (L) Risk of global slope instability affecting the proposed development subject to the
                implementation of recommendations given below. 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 2 on the page below is our qualitative assessment of landslide risk for the site. A summary of
                qualitative terminology for use in assessing risk to property is attached (taken from AGS 2007).
