               storm water system.
           □   Erosion and Sediment Control for the proposed terrace will
               require a silt fence to the perimeter of the proposed footing
               excavation.
           □   The permanent storm water drainage system will be connected
               to the Council system as an early works operation to prevent
               any concentrations of runoff discharging onto the sand slope.

    Environmental Controls Plan to prevent pollution from
    concreting operations during the construction (Grouting & Pile
    Caps)

    Background.

    The use of concrete materials is reduced to a minimum due to the use of
    a micro piling system which is to be craned onto site.
    The small volumes of concrete required allow the use of a small
    concrete grout pump with reduced line size to grout piles and concrete
    pile caps.
    This system gives precise control to the operators making spillage and
    cleaning requirements negligible.

    Controls:
    The builder/site manager will ensure the following best practice sediment
    control measures including a designated wash down area are in place
    before work starts and are adequately maintained throughout construction.

•    The designated wash down area is to be located within the site on the
     existing paved driveway with sediment control screening in place and
     an appropriate HDP waste receptacle drum will be available to retain
     any sediment waste from swept up spillage or cleaning of equipment.
