                                          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:
                                                   1. upstream runoff is diverted around the
                                                      construction site;
                                                   2. 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
                                                   3. temporary or permanent downpipes are
                                                      connected to the stormwater system before laying
                                                      the roof; or
                                                   4. localised erosion is avoided by directing flow from
                                                      downpipes over non-erosive areas.

                                          AO14.4
                                          Chemical flocculants used as part of an erosion and sediment
                                          control plan do not harm the environmental values within
                                          receiving waters.

                                          AO14.5
                                          Appropriately sized litter containment areas, with provision for
                                          sorting recyclables are provided for the type of litter expected to
                                          be generated onsite.
