SUPERSEDED SPA Decision Notice - 010.2010.00000871.001 [As Published] · 132010.871

                                                                                           2010/871




      35.2. Stormwater runoff from the yard and driveway areas must be treated within the site and
            discharged in a controlled manner as overland flow into the National Park. The
            discharge must mimic existing drainage patterns and not cause scour or damage to the
            National Park or the subject site.
             Plans of the drainage design must be prepared by a Registered Professional Civil
             Engineer and submitted to Council prior to obtaining a Development Permit for
             Operational Works.
             The maximum discharge of stormwater drainage allowable to Council’s kerb & channel
             street drainage system at any one location is 25 litres/second
36.   To ensure that polluted run-off does not enter Council’s stormwater drainage system or the
      adjoining National Park, stormwater run-off from the carparking areas and the driveways must
      have the first flush (the first 12 mm of rainfall or hose-down) collected in a grease/oil
      arrestor/gross pollutant trap provided on site prior to being permitted to discharge from the
      site.
      To this end, a detailed maintenance plan must be prepared for the proposed grease/oil
      arrestors/gross pollutant trap, which must be submitted to the Council for approval prior to
      obtaining a Development Permit for Operational Works.
      The approved maintenance plan must be incorporated in the Community Management
      Scheme for the development and a copy of this must be provided for Council’s records prior to
      commencement of the approved Use.
      A Development Permit for Building Works must not be granted until a Development Permit for
      Operational Works has been issued in regard to the drainage scheme.
37.   All site stormwater drainage must be by means of a gravity system.
Earthworks
38.   Earthworks required on site must be carried out in accordance with Council’s Planning
      Scheme Policy PSP5 – Engineering Design Standards, so as not to cause the additional
      ponding of water on any adjoining lands or the blockage of, or interference with, any natural
      watercourses.
39.   Earthworks carried out on site must not affect the structural integrity of any of the existing
      fences and/or structures and/or lands that border the development site. Fences that are
      affected must be replaced prior to the Building Certifier issuing the Certificate of Classification.
      In this regard any fences to be replaced must be clearly shown on the plans submitted for
      Operational Works approval.
Site Stability
40.   A Geotechnical Engineer or similar qualified expert must assess the soil condition on site,
      determine the soil classification, establish whether any measures are required to protect the
      stability of adjoining buildings and/or structures and/or land, and make recommendations on
      the type of foundation system(s) best suited for the proposed development. The
      recommendations of this report must be incorporated into the design and construction of the
      proposed development.
Erosion and Sediment Control
41.   Any person acting on this permit must prevent erosion and sediment export from leaving the
      site. Site control measures such as silt fencing, controlled gravel access to the site and
      controlled disposal of waste, will be necessary. In this regard plans detailing the methods of
      controlling erosion and sediment are required to be submitted to the Council prior to obtaining
      a Development Permit for Operational Works.
42.   A suitably qualified Registered Professional Engineer must prepare engineering drawings and
      specifications for all engineering works that will become Council infrastructure, which must be
      submitted in conjunction with an application for a Development Permit for Operational Works.
