                  Rehabilitate the fauna corridor area post construction in relation to the construction

As a consequence of the above advices, further investigations into the designs of the various basins
associated with ’Option 3’ were undertaken, and in doing so, an alternate location for the proposed

Twigrush basin was proposed (refer attached sketch) affecting the alignment of the ’link road’. This
sketch was provided to Council on 27 March 2013 seeking confirmation that Council had no
fundamental concern with the proposal, wherein we were subsequently advised by Senior

Development Planner Denis Wallace (by email dated 3 April 2013):-
                       -




    I confirm that we’ve no fundamental concern with the Twigrush basin proposal. Mark Lewis draws

    your attention to the following:


         .   You need to ensure that the proposed T-intersection beside the basin is suitable for the
             intended use (local traffic and bus route) and that the required geometry/sight lines are
             achievable.


         .   It would desirable in any rearrangement of the lots that sufficient space is left for

             pedestrian paths and for maintenance access to the basins. Maintenance for the
             relocated basin should be from the lower order streets not the link road.


Based on the above, Brown Consulting (QLD)Pty Ltd have completed a review of the Stormwater

Management Plan solution for Stage C of Doonella Noosa, which achieves the fundamentally agreed
outcomes of both Council and Stockland Lake Doonella Pty Ltd (refer attached Updated Management

Strategy).   Please note, the Updated    Management Strategy has been prepared in addition to the
following previously provided documents:-

.   Flood Investigation & Stormwater Management Plan (Report No. B09182.w-02A dated October

    2011) prepared by Brown Consulting (QLD)Pty Ltd (provided with original request for a pre-
    request response); and


.   Letter from BMT WBM        (formerly WBM Oceanics) summansmg revised                 Stormwater   Quality

On the anticipation that the revised design and modelling is acceptable to Council, we would like it to

replace the previous report that was prepared by WBM and is referred to in the approval.                   We

appreciate that this will require a change Condition 46 and Condition 49.

In response to the Updated Management Strategy, a number of changes to the layout were necessary
to accommodate the stormwater solution. These changes are relatively minor in nature and broadly
consist of the following:-
