SUPERSEDED - Change to an Existing Approval (Construction Staging Plan) [As Published] · 132003.221132.7

                                                                                        2003/221132

126. A registered practicing Geotechnical Engineer shall test the existing ground conditions for
     suitability of placing additional fill, prior to such fill being placed.
127. Any existing fill or natural materials on the site or with the extent of approved works external to
     the site which do not satisfy a Geotechnical Engineer's requirements shall be removed and
     replaced with suitable material.
128. Fill shall be compacted to 95% relative dry density as per Main Roads Department Test No.
     Q8A. A registered practicing Geotechnical Engineer shall supervise all the placement of fill
     and shall certify that all lots have been compacted to the required standard.
129. Following completion of the filling works and prior to endorsement of the Plan of Survey, the
     registered practicing Geotechnical Engineer supervising the works shall submit compaction
     tests across the entire filled areas and a site classification report for each lot subject to filling.
     The extent of fill and each lot site classification shall be shown on a metes and bounds survey
     plan.
130. An appropriate property notation shall be placed on Council's rates records to advise
     prospective purchasers of lots that have been filled that special foundations requirements will
     apply.
131. Stormwater is to be disposed of on site so as to cause no scour or damage to adjoining
     properties to the reasonable satisfaction of the Manager - Land Development. A Development
     Permit for Building Works shall not be granted until a Development Permit for Operational
     Works has been issued in regard to the drainage scheme.
132. The stormwater discharge from the site shall be designed such that there is no net increase in
     the rate of discharge as a result of the development for storm events up to 100 year ARI.
133. Tabulated hydrologic and hydraulic calculations that demonstrate the adequacy or otherwise
     of the existing site stormwater drainage system shall be submitted in conjunction with a
     Development Permit for Operational Works. Such calculations shall include any remedial
     measures necessary to rectify defects in the existing system. Where proposed site drainage is
     to be connected to the existing system, the calculations shall clearly demonstrate the
     adequacy of the existing drainage network to accept the additional stormwater flows.
134. Stormwater drainage shall include measures to protect proposed allotments from run-off from
     or to surrounding land. The design shall also address controls for gross pollutants, nutrient
     runoff, oil and grease, and silt and sediment (in accordance with the approved Environmental
     Management Plan).
135. Underground stormwater systems shall be designed in accordance with Noosa Council’s
     Engineering Design Standards, and shall be connected, where possible to Council's existing
     drainage systems.
136. An easement of minimum width 4.0 metres shall be granted in favour of Council over any
     stormwater pipes that traverse private property.
137. The design plans detailing surface levels, which shall be controlled across the site of the
     development to create a major storm event overland flow path system to cater for the 1:100
     year design storm, shall be submitted in conjunction with a Development Permit for
     Operational Works. Any overland flow from external catchments shall be accepted and
     incorporated in the major event surface flow drainage system through the site. Overland flows
     shall be discharged in a safe manner and the product of velocity time depth shall not exceed
     0.4 m²/sec.
138. The design plans are to show how stormwater runoff within and from the site is to be
     controlled both during construction and permanently. The plans are to indicate measures to be
     taken to prevent erosion and the export of sediment from the site in accordance with the
     approved Environmental Management Plan.
139. An easement for drainage in favour of Council shall be created over the full length and width of
     major storm event surface flow paths within the site at no cost to Council.
                                                                                       Page 21 of 27
