 ADDENDUM REPORT
 SLOPE STABILITY ASSESSMENT
 400 COOROY MOUNTAIN ROAD, COOROY


 Dear Mark,

 We understand that the layout for the proposed residence at 400 Cooroy Mountain Road, Cooroy has been
 altered since the issue of Tectonic’s geotechnical investigation and slope stability assessment report (Ref.
 17385-001-RevO, dated 27 November 2017). We have been provided with recent correspondence from
 Noosa Shire Council (NSC) which stated the following:

            “An exemption certificate is required for the new pool deck being located within a landslide hazard
            area, on the basis that the works have not commenced.” The deck has increased in size with a
            considerable extent of the works proposed within the landslide hazard area. We [NSC] will require
            an updated site-specific geotechnical report that addresses the risks associated with the new pool
            deck.”

 The pool deck, forming the subject of this addendum report is shown below in Text Figure 1, being an
 extract of the layout drawings supplied to us (Ref. Tony Walton Designs, Job No. 042/17, Dwg No. 06, Rev
 I, dated 12 November 2021).
