        5.   Revise surface treatment proposed for swales so that it is low maintenance and likely
             to maintain its modeled configuration during the long term and consistent with the
             requirements of the approved management plans.

        Drawings have been revised to remove reference to turf in swales (despite its successful use on
        previous adjacent stages). We defer to the landscape architect for details of swale planting.


        6.   Detail the RL of the overflow of the underground rainwater tanks and inlet to the Rapid
             Infiltration Pits on the submitted drawings.

        We note that proposed rainwater harvesting tanks as indicated on drawing D01 B occur above
        proposed ground floor levels of RL14.0m/10.5m AHD and the tops of the proposed RIP's are to
        be at RL13.0m/9.0m AHD respectively.

        As such there will be no shortage of fall or gradient required to achieve adequate overflow of
        tanks to the RIP's.

        Building drainage, guttering, spouting, etc is beyond the scope of this Operational Works
        application and hence details of such are not included at this time but will be addressed in future
        hydraulic consultant's applications as appropriate.


        7.   Demonstrate that runoff from the driveway and basement areas will be able to drain
             from the site via gravity.

        Driveway runoff collected at basement level (RL10.5m AHD) will be treated via a second Fox
        Enviro BPT 600 grease arrestor and discharged via gravity to RIP'S 2a/2b at Swale 2 (RL8.8m
        AHD). Refer revised drawing D01 B.


        8.   Provide amended plans that indicate the width of the access driveway in accordance
             with Condition 23 of the Decision Notice 2008/175 dated 12t1i August 2009.

        Drawing R01 B has been amended accordingly.




We trust,this adequately addresses all issues raised and look forward to receipt of a decision notice.
