Decision Notice - Change to an Existing Approval - 010.2006.00000823.003 [As Published] · 132006.823.03

                                                                                         2006/823

220. The final locations of the boulder retention fences are to be determined on site by agreement
     between the Manager – Land Development and the Developer having regard to the protection
     of vulnerable plants and their habitat. Approximate locations of the boulder fences are shown
     on the Site Plan Drawing no.: 1013 DA-01-01 Issue 4 dated 30 August 2006 and prepared by
     JMA Architects.
Geotechnical
221. Conditions are to be undertaken:
      221.1.by an experienced Registered Professional             Engineer of Queensland             having
            geotechnical qualifications;
      221.2.to the reasonable satisfaction of the Manager – Land Development; and
      221.3.prior to lodgement of any development applications for building or operational works.
222. The Developer shall prepare and implement a treatment strategy for areas of existing fill with
     unknown compaction history, including reference to the expected extent of areas of
     disturbance. The intention of this strategy is to address areas of existing fill within the
     development area. This strategy shall be in accordance with requirements of the EPA and
     contaminated areas on the site.
223. The stability of the steep slopes above the proposed, Blocks A, B, C, D, E and G, shall be
     subject to a detailed assessment. The assessment shall include:
      223.1.sufficient sub-surface investigations to assess the depth of colluvial soils in these areas;
      223.2.circular and non-circular methods of analysis;
      223.3.the effects of groundwater as perched water tables and/or water filled tension cracks.
      Slope stabilisation measures, if required, shall be identified and implemented.
224. A qualified geo-technical engineer shall undertake further assessment of areas of fissured
     clays and provide details of engineering support that will reduce the risk of slope instability for
     the subject buildings. The type of engineering support shall be designed to ensure no impacts
     on existing vegetation, particularly within the 10 metre setback zone to the creek. An RPEQ
     shall design and certify that all footing excavations have been undertaken to best practice and
     are structurally sound for the site conditions.
225. An RPEQ shall design the footings for all building works that require earthworks within the
     fissured clay areas as identified by Golder Associates. The RPEQ shall certify that these
     footing designs are structurally sound for the site conditions.
226. The Developer shall provide to Council an assessment of the effects of de-watering of any
     basement excavations for the Resort buildings.
Filling and Excavation
227. Detailed plans and specifications based on and generally in accordance with the Engineering
     Drawings in relation to earthworks (and prepared after consultation with the Manager – Land
     Development) are to be submitted with the relevant applications for either plumbing, drainage,
     building or operational works.
228. All filling and/or excavation works are to be carried out strictly in accordance with any
     development permits for plumbing, drainage, building or operational works, and approved
     management plans.
