                                                                                                                                                 Peregian Beach Caravan Park




                               -   Install a high pressure water hose that can reach the rock pad, to remove cohesive mud.
                         Designated on-site stockpiles

                                   Have a designated site for stockpiling excavated earth, building sand and building materials. Ensure that the stockpiles have
                                   designated covers with pegs to protect them from wet weather, and are sufficiently distant from kerbside drains;
                                   Install a geo-log upslope of stockpile area to divert flow around the stockpile;
                                   Install a sediment fence down-slope of stockpile area to collect sediment; and
                                   At the end of each day, or before the onset of rain, cover and securely peg stockpiles.
                         Downslope sediment controls

                                   Install geo-textile sediment fences on the lower slopes of the building site. Posts should be minimum of 2m spacing; the base
                                   should be buried at least 200 mm below ground. The fences should be concave upslope to bund stormwater, while allowing
                                   lateral overflow down-slope;

                                   Stabilise ground that accommodates overflow from the sediment fences to avoid rill development (refer to 'Maintaining
                                   groundcover';

                                   Direct overflow into down-slope sediment fence. Use filter socks as a final barrier to contain suspended sediment. Overflow from
                                   the filter socks will be into the terminal wetland. Use water from the terminal wetland to irrigate ground cover (refer to
                                   'Maintaining groundcover);

                                   Install a sediment curtain in the terminal wetland to contain any fine sediment in overtopped stormwater; and
                                   Install temporary downpipes from newly constructed roofs.
                         Maintaining groundcover

                                   Maintain existing grass cover as much as possible. Reduce damage to grass cover by limiting vehicle movements to work areas
                                   and designated access tracks;
                                   Cover disturbed ground under erosion blanket, secured with pegs and with the edge buried below the soil surface;
                                   Reseed disturbed soils that will be left bare, using hydromulch or equivalent. Irrigate reseeded area daily for four weeks to
                                   establish the grass surface; and

                                   Lay turf in areas where concentrated flow is expected (e.g. at the overflow of sediment fences).
