ORDINARY MEETING AGENDA                                                       17 AUGUST 2017


              c.    Have all access chamber surface levels for drainage, water supply or
                    sewerage infrastructure within the work site be adjusted to provide a
                    freeboard of 100mm above the finished ground surface level or be in
                    accordance with the requirements and directions of the service provider.
              d.    All fill and associated batters must be contained entirely within the subject
                    site unless written permission from the respective landowner(s) is
                    provided to Council.
                    (*) refer to Advisory Notes
        Acid Sulfate Soils
        38.   Where excavations of non-imported soils below the elevation of 5m AHD are
              necessary for construction, the application for Operational Works for Bulk
              Earthworks, Stormwater and /or Landscaping must demonstrate and include
              certification from a suitably experienced and qualified geotechnical engineer of
              methods necessary to ensure construction and operation of the development:
              a.    Shall be consistent with Queensland Acid Sulphate Soil Technical
                    Manual: Soil Management Guidelines; and
              b.    will not result in the release of acid or associated metals; and
              c.    will not cause localised lowering of groundwater.
        Erosion and Sediment Control
        39.   Prior to the completion of the development, all site surfaces must be effectively
              stabilised. For the purpose of this condition, an effectively stabilised surface is
              defined as one that does not, or is not likely to result in visible evidence of soil
              loss caused by sheet, rill or gully erosion or lead to sedimentation, or lead to
              water contamination.
        Water Quality and Quantity
        40.   Except as otherwise modified herein, the development must be designed,
              constructed and maintained to achieve the stormwater quality and quantity
              outcomes detailed in the Site Based Stormwater Management Plan for 30-32
              Doonella Street, Tewantin Rev C by Bornhorst and Ward dated May 2017.
        41.   The development must include measures to prevent oils, hydrocarbons or other
              pollutants likely to be released in basement areas from being released into
              Council’s Stormwater system or other receiving waters.
        42.   Water quality treatment devices must be shaped and designed to be low
              maintenance, and integrate into the landscape. Where bioretention devices are
              proposed, the Operational Works Application for Stormwater Drainage,
              Landscaping and Earthworks must demonstrate how the design is consistent
              with the most current version of the Water by Design Bioretention Technical
              Design Guidelines.
        43.   Water Quality Treatment devices must be operated and maintained in
              accordance with manufacturer’s specifications and relevant maintenance
              manuals.
        44.   Prior to commencement of use the Community Management Statement must
              include provision for the engagement of personnel to operate and maintain
              Water Quality Treatment devices in accordance with manufacturer’s
              specifications, relevant maintenance manuals and the Site Based Stormwater
              Management Plan for 30-32 Doonella Street, Tewantin Rev C by Bornhorst and
              Ward dated May 2017.
