     prepared by Soil Surveys Engineering Pty Ltd titled, Acid Sulfate Soils Investigation, Weyba
     Ranch and dated July 2003.
Earthworks
160. Filling works required on site shall be carried out in accordance with Section 3.8 of Council’s
     Engineering Design Standards Manual and so as not to cause the ponding of water on any
     adjoining lands or the blockage of, or interference with, any natural watercourses.
      This will require the design and construction of drainage pipes within the development site that
      cater for drainage within the adjoining sites and in this regard a Development Permit for
      Operational Works shall be obtained.
161. Where a change in the levels of the site outside of an existing or proposed road reserve is
     approved, the site shall be filled or cut so that each lot drains towards a road frontage unless a
     proposed drainage system will collect stormwater from off each lot and discharge the
     stormwater to an adequate Council stormwater drainage system.
      Such works undertaken on the site shall be carried out in accordance with Section 3.8 of
      Council's "Engineering Design Standards" Manual so as not to cause any ponding of water on
      any adjoining land, or the blockage of, or interference with any natural watercourses.
162. A registered practicing Geotechnical Engineer shall test the existing ground conditions for
     suitability of placing additional fill, prior to such fill being placed.
      Filling works shall be restricted to the subject site itself, and the finished fill levels are to taper
      to the existing levels prior to the rear boundary of the property. Batters shall be at a maximum
      grade of 1:4 unless retained by a wall.

      Any existing fill or natural materials on the site or with the extent of approved works external to
      the site which do not satisfy the Manager - Land Development's or a Geotechnical Engineer's
      requirements shall be removed and replaced with suitable material.
163. 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.
      Any existing fill on the site that does not comply with Council’s requirements shall be removed
      at the direction of the Manager - Land Development prior to additional filling works
      commencing.
164. 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.
165. 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.
