Decision Notice OPW25 0154

               2.     Council reserves the right to call up any performance bond held or levy charges against the
                      property, should emergency works be required to be undertaken by Council to make the site
                      safe due to inactivity on the development site for extended periods of time.
               3.     Should any changes or modifications to the approved plans be required as a result of
                      construction constraints, a “Request to change an existing approval” under the Planning Act
                      2016 must be made. Amended plans clearly indicating the changes must be lodged with this
                      application along with the appropriate fees.
                      Qualified Person
               4.     For the purpose of preparing a Geotechnical Report, and for certifying geotechnical stability
                      for the development, a qualified person is considered to be a person who:
                      a.      is a Registered Professional Engineer of Queensland (RPEQ); and
                      b.      has a degree in civil engineering or engineering geology; and
                      c.      has a minimum of 5 years experience in the field of geotechnical engineering or
                              engineering geology.
                      Environmental Advisory Notes
               5.     The Environmental Protection Act 1994 states that a person must not carry out any activity
                      that causes, or is likely to cause, environmental harm unless the person takes all reasonable
                      and practicable measures to prevent or minimise the harm. Environmental harm includes
                      environmental nuisance. In this regard persons and entities, involved in the civil, earthworks,
                      construction and landscaping phases of this development are to adhere to their ‘general
                      environmental duty’ to minimise the risk of causing environmental harm.
                      Erosion and Sediment Control
               6.     Accepted best practice standards include International Erosion Control Association
                      Australasia Best Practice Erosion and Sediment Control.
               7.     Qualified Person, for the purpose of erosion and sediment control is a Certified Professional
                      in Erosion and Sediment Control (CPESC) or suitably experienced Registered Professional
                      Engineer of Queensland (RPEQ).
               8.     As a general rule, a site is determined to have achieved effective short-term stabilisation if
                      at the time of the plan sealing inspection:
                      a.      Methods of stabilisation are:
                              •    appropriate for slopes and slope lengths; and
                              •    are consistent with best practice environmental management practices such as in
                                   the Manual for Erosion and Sediment Control or the IECA Manual; and
                      b.      Stormwater runoff from the site is not currently, and is not likely to result in visible
                              evidence of sedimentation or erosion, or lead to water contamination.
                              If at the time of request for plan sealing, the method of short-term stabilisation has not
                              achieved a level of stability that Council's Officers believe will have a high probability
                              of achieving long term stability (i.e. until house construction has occurred on all lots),
                              Council Officers may take the following matters into consideration in determining
                              whether the site is capable of achieving medium to long-term stability:
                              •    evidence that the site has been effectively stabilised in the short term;
                              •    evidence that soil has been adequately ameliorated;
                              •    evidence that seed of annual and perennial grass species has been applied at an
                                   adequate rate; and
                              •    that grass seed has germinated at a density that is likely to achieve an effective
                                   grass cover.
                              For example, while hydromulch can provide an immediate and effective stabilising
                              cover to soils, the protective cover can be relatively short-lived if vegetation fails to
