                SLOPE STABILITY ASSESSMENT FOR PROPOSED NEW DRIVEWAY
                182 UHLMANNS ROAD, FEDERAL



                Dear Natalie

                1.0       INTRODUCTION
                Tectonic has undertaken a geotechnical assessment for a proposed driveway at 182 Uhlmanns Road,
                Federal. This report includes a slope stability assessment, together with geotechnical advice for the
                proposed development. In summary, subject to implementation of the recommendations made herein,
                there would be a Low Risk of slope instability affecting the proposed driveway, with the proposed driveway
                assessed to have a non-worsening effect on the existing slope stability of the site, proposed areas of work
                and the adjoining properties, in accordance with the Australian Geomechanics Society Guidelines for
                Landslide Risk Management, dated March 2007 (AGS 2007).

                It is understood that this report will be submitted to Noosa Council (NC) to address Item 3 of an Information
                Request (NC Ref. RAL22/0032, dated 14 December 2022).

                1.1     Details of Site and Proposed Development

                The site is described as Lot 147 on M371248, covers an area of about 9.3 ha, and has frontage to Uhlmanns
                Road in the north-western corner. At the time of the assessment two residences were located in the north-
                western part of the site, with the proposed driveway to extend between the two structures down to Uhlmanns
                Road. Two additional residential structures were located in the central part of the site, well away from the
                proposed development area. Semi-rural and acreage allotments with scattered buildings surrounded the
                site. A 2022 aerial image of the site and surrounds is shown in Text Figure 1 overleaf. A detailed
                description of the site is given in Section 2.
