Minor Change Existing Approval - 152000.200053.3 (As Published)

               50.    Plans detailing the proposed site drainage network including plans and longitudinal sections
                      of pipeline, the location of pits, pipe invert and pit surface levels, junction details, size and
                      class of pipes, trench conditions and details of surface flow paths together with tabulated
                      hydrologic and hydraulic calculations that detail the drainage network and the capacities of
                      the various surface flow regimes shall be submitted to in conjunction with a Development
                      Permit for Operational Works.
                      Where flows are in excess of 100 litres/second then a hydraulic grade line analysis will be
                      required.
               51.    A Stormwater Management Plan addressing controls for gross pollutants, nutrient runoff, oil
                      and grease, and silt and sediment will be required to be submitted to Council for approval
                      prior to issue of a Development Permit for Operational Works. The Stormwater Management
                      Plan shall operate on the principle of “no net increase” in nutrients and other pollutants.
               52.    Stormwater drainage shall include measures to protect proposed allotments from run-off from
                      or to surrounding land. Underground stormwater systems shall be designed in accordance
                      with Noosa Council’s Engineering Design Standards.
               53.    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 and will embrace the
                      principles set out in the Institution of Engineers Australia Engineering Guidelines for
                      Queensland Soil Erosion and Sediment Control, June 1996. Designs shall also incorporate
                      the principle of “no net increase” in nutrients and other 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.
               54.    Property drains including field inlets shall be provided along the rear of all lots falling away
                      from the road where roof water is unlikely to be connected to the frontage kerb and channel.
                      Property drains shall be designed to carry roof water and allotment surface drainage. The
                      minimum size shall be 150 mm diameter UPVC. Property drains shall be located in a 1.5
                      metre wide easement.
                      The terms of the easement shall include the responsibilities on the beneficiaries of the
                      easement to maintain the drain so as to be operational at all times.
                      A property notation shall be added to Council’s rates record advising prospective owners that
                      they are responsible for maintenance of the property drain.
               55.    The proposed names of new roads (public and private) and parks shall be lodged with the
                      application for a Development Permit for Operational Works.
                      Names are to be selected from any of the following categories:-
                      55.1. Easily pronounced words of Murri languages.
                      55.2. Names or words of local significance or historical interest.
                      55.3. Flora, fauna, industry, topographical, geological and similar features and terms relative
                            to the district.
                      55.4. Surnames of persons of merit or historical significance. (Personal names should be
                            avoided.)
                      All street signs on new roads (public and private) and parks shall be erected prior to works
                      being accepted on maintenance. For private roads and parks, Council will provide the
                      nameplate and signpost to the Applicant upon payment of $250 per sign.
               56.    Prior to endorsement of the Plan of Survey, a State Survey Mark shall be provided within the
                      site. It shall be levelled and located to the requirements of the Manager - Land Development.
                      A ‘Form 6’ shall be submitted for Council's records.
                      Each State or other Permanent Survey Mark shall be installed clear of overhead vegetation,
                      making it suitable for Global Positioning Equipment, and accurately connected to at least one
                      real property corner by a registered Surveyor.
