SLOPE STABILITY ASSESSMENT
PROPOSED DUAL OCCUPANCY DEVELOPMENT
168 EDWARDS STREET, SUNSHINE BEACH

Dear Adam,

1.0     INTRODUCTION
As requested, Tectonic has undertaken a geotechnical investigation for the proposed dual occupancy
development at 168 Edwards Street, Sunshine Beach. This report presents the results of our geotechnical
investigation, incorporating a slope stability assessment, together with geotechnical advice for the project.
In summary, subject to the implementation of the recommendations made herein, it is assessed that there
would be a Low Risk to the proposed development from slope instability in accordance with the Australian
Geomechanics Society Guidelines for Landslide Risk Management, dated March 2007 (AGS 2007).

1.1    Details of the Site and Development

The site is described as Lot 35 on RP48113, covers an area of about 607 m2, and has frontage to Edwards
Street along the south-western boundary. Edwards Street runs parallel with David Low Way, which was
present just below Edwards Street, with an earthworks cut between. The site was vacant at the time of our
assessment, with similar sized developed residential blocks surrounding otherwise. A 2019 aerial image of
the site and surrounds is shown in Text Figure 1 below. A more detailed description of the site is given in
Section 2.
