Request change to an approval 152004.240078.4

                                                                                          152004.240078.1


             Designs that concentrate stormwater onto adjoining land shall require separate formal
          --approval fromlheowner-af1he and- -re1evant-Gbvernmenr-AUlnotity.-Suchappr val----
-------




             shall-be submitted with the design in -conjunction with-an -application -ror-a -Development
             Permit for Operational Works.

     41.     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
             100 year design storm, shall be submitted in conjunction with a Development Permit for
             Operational Works. Any overland flow from external catchments shall be ccepted and
             incorporated in the major event surface flow drainage system through the development
             site. Overland flows shall be discharged in a safe manner and the product of velocity
             times depth shall not exceed 0.4 m2/sec.

     42.     The design plans are to show how stormwater run.-off 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 and

             will embrace the principles set out in the Institution of Engineers, Australia, Queensland
            -Givision, "Soil Erosien -and Sediment Control --Guidelines for-Queenslahd -Construction
             Sites", June 1996.

            Designs shall also incorporate the principle of "no net increase" in nutrients and either
            pollutants from the developed site. This may require the provision of a drainage system
            that allows first flush (first 12mm of rainfall) to be collected and treated prior to release
            into the downstream drainage system.

     43.    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 development site at no cost to
                                                                                          .




            Council.

     44.    Underground stormwater systems shall be designed in accordance with Noosa Council’s
            Engineering Design Standards, and shall discharge, where possible, into the wetland
            system, as far upstream as practical. Appropriate stilling and energy dissipation
            measures shall be incorporated at outlets.


     45.    Suitable overland escape routes are to be provided for stormwater run-off in excess of
            the piped design frequency.

     46.    All concrete pipes within road reserves and within drainage easements intended to be
            dedicated to Council shall be inspected by closed circuit television (CCTV). A copy of
            the CCTV inspection shall be recorded on videotape and submitted to Council prior to
            endorsement of the Plan of Survey / prior to commencement of the Use.

     Weed Clearance


     47.    All Class 1, Class 2 and Class 3 pest plants declared under the Land Protection (Pest
            and Stock Route Management) Act 2002 are to be controlled on the site prior to Council
            endorsement of the plan of survey. In this context "controlled" shall mean, for class 1
            and 2 pests, completely eradicated. For class 3 pests it shall mean removal of the plants
            where they threaten environmentally significant areas of the site such as riparian zones
            and areas of natural vegetation.

            Where class 3 plants are removed as a result of this condition and there is not sufficient
            natural regeneration of native species, the areas shall be replanted with endemic native
            species so that a sustainable natural ecosystem is restored.
            Council’s Conservation        Management Supervisor will not inspect the site until 30 days
            after the weed treatment and replanting is complete.
