 Criteria                                             COMMENT
 History:                                             Based on the Noosa Shire Council website this area is
                                                      tagged with susceptibility to landslide.
 Current Stability:                                   No signs of instability in the slope.

 Stability of Adjoining Properties:                   Residential block with proposed new dwelling
                                                      construction. Will have no stability effects on
                                                      surrounding properties.
 Requirement for Retaining Structures:                Dependant on excavations and design. If required,
                                                      retaining walls are to be designed by appropriate
                                                      engineers. If retaining walls are greater than 2.5 m, this
                                                      office should be advised.
 Special Design Features Required:                    Nil.

 Special Surface or Sub-Surface Drainage              Nil.
 Measures:
 Evidence of Previous Instability:                    Nil.

 Assessment of Surface Drainage:                      Good – Flow generally heading towards the southwest.
                                                      Attached is an example of prudent site drainage
                                                      measures.
 Assessment of Sub-Surface Drainage:                  N/A

 Building Site Stability:                             With respect to the assessed hazard risk, Protest
                                                      Engineering zone this site as ‘low’.
 Long Term Stability of Building Site and Building:   Provided the (soil) information is correct, good practice
                                                      for surface drainage is followed, the engineer designs
                                                      were carefully followed, the site and dwelling stability
                                                      should be considered as ‘low’ hazard.
