Attachment A - Approved Decision Notice MCU210027

                      d.      1 in 2 for combined structural engineering and planting solutions.
                      Stormwater Drainage
               29.    Appropriate scour protection must be provided at the outlet of all stormwater pipes including
                      temporary outlets.
               30.    Works associated with this permit must not adversely impact on the existing drainage
                      conditions on other properties (e.g. by blocking or interfering with natural overland flows).
               31.    Construction of all internal stormwater drainage works must comply with the relevant
                      section/s of Australian Standard AS/NZS 3500.3.
                      Erosion and Sediment Control
               32.    Prescribed Water Contaminants (as defined in Schedule 10 of Environmental Protection
                      Regulation 2019) must not be released from the site or to waters within the site, or be likely
                      to be released should rainfall occur, unless all reasonable and practicable measures are
                      taken to prevent or minimise the release and concentration of contamination.
               33.    Sediment and erosion control measures must be in place prior to works commencing. If such
                      measures are not in place or are not satisfactory, “on the spot” fines may be issued. Such
                      fines can be issued if sediments from the site are found to enter or have the potential to enter
                      Council’s stormwater system, natural waterways, any downstream stormwater filtration
                      system or adversely impacting on other properties. The sediment and erosion control design
                      and measures have NOT been approved, it is the site's Supervising Engineer who is
                      responsible for ensuring that the sediment and erosion control measures have:
                      a.      Been duly designed by an RPEQ or CPESC and constructed in accordance with "best
                              practise" methods;
                      b.      Been revised by an RPEQ or CPESC to address the issues raised by changes in the
                              projected construction schedule and/or methods;
                      c.      Been revised to address predicted rainfall events; and
                      d.      Achieve the desired environmental outcomes.
                      Council may request further controls to be installed should the implemented measures be
                      found inefficient.
               34.    The erosion and sediment control measures must be designed, installed and maintained in
                      accordance with the supervising engineer instructions and the current best practice
                      standards * (Refer to Advisory Note).
               35.    The developer must ensure non-essential exposure of soil is prevented by restricting the
                      extent of disturbance and minimising the duration of soil exposure to adverse weather
                      conditions and effectively turf, cover or stabilise any disturbed area without delay and prior
                      to rainfall occurring.
               36.    The developer must ensure sediment does not leave the site or enter onto adjoining
                      properties or Council’s drainage system due to surface runoff or on tyres of vehicles and/or
                      machinery. It is essential to implement appropriate approved erosion and sediment control
                      measures throughout the site during all phases of construction including vehicle shakedown
                      pad/grid (or similar) at the access to the construction site. Where sediments or other
                      contaminants are deposited on a road, they must be removed so as not to enter Council’s
                      drainage system or waterways.
               37.    Prior to the completion of the development and commencement of use, all site surfaces must
                      be effectively stabilised using methods which have achieved effective short-term stabilisation
                      and which will continue to achieve effective stabilisation in the medium to long-term. 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.
