                                                 watercourse, such should occur at 90 degrees with
                                                 bridging favoured over the use of embankments,

                                                 should be demonstrated in plans as:
                                                 a) Minimising clearing of riparian vegetation;
                                                 b) Minimising areas affected by earthworks and
                                                 other construction activity (e.g. use of pillars);
                                                 c) Minimising substrate disturbance;
                                                 d) Preventing realignment of natural waterways;
                                                 and
                                                 e) Avoiding engineering solutions for scour control.
