Erosion and Sediment Control
O1    Development minimises            S1.1 Site disturbance is limited to    Sediment and erosion control
erosion   and     transport of         building areas, their surround and     plans will be generated as part of
sediments off-site.                    other use areas;                       the operational works (civil)
                                       AND                                    design drawings to address all

                                       fine or dispersive soils;

                                       catchpit protection device is
                                       installed so that all runoff from
                                       disturbed areas flows to the
                                       catchpit;

                                           by    directing   flow  from
                                           downpipes over non-erosive
                                           areas.
Stormwater Runoff
O2    Stormwater is diverted           S2.1 Diversion drains or bunds         Part of the sediment and erosion
around disturbed areas.                are designed and constructed to        control mentioned above may
