   4.6   Slope Stabilitv


      The site is located within an area of Sunshine Beach known as "Sand Dune Problem
      Areas". As such, an assessment of the overall stability of the site and surrounds has been
      carried out by an experienced         Geotechnical     Engineer   at the same time as the
      geotechnical investigation.


      Published contour information (Sunshine Coast Regional Council) has been used to
      determine slope angles and slope heights. Refer Figure 4 below.
