                                         AO14.2
                                          Construction works are designed
                                         and managed to restrict the extent of
                                         clearing and soil exposure to the
                                         minimum necessary for access, and
                                         safe construction at any one time.




                                         AO14.3
                                         For buildings:

                                         (a) upstream runoff is diverted
                                             around the construction site;
                                         (b) sediment barriers are provided
                                             downslope of disturbed areas to
                                             prevent sediment washing into
                                             gutters, drains and waterways ,
                                             wetlands or drainage lines either
                                             on or off the site; and
                                         (c) temporary or permanent
                                             downpipes are connected to the
                                             stormwater system before laying
                                             the roof; or
                                         (d) localised erosion is avoided by
                                             directing flow from downpipes
                                             over non-erosive areas.

                                         Chemical flocculants used as part of
                                         an erosion and sediment control plan
                                         do not harm the environmental
                                         values within receiving waters.
