Information response

20.    Provide written approval for the proposed access driveway from the authority benefitted by
       the easement (ENERGEX).

Response:
Refer Energex Referral response included within Attachment 2 which provides support for approval of
the application subject to conditions for works within the easement area and within vicinity of the
Energex structures.

21.    Provide additional detail on the proposed clearing and landscaping within the critical sight line
       areas. Provide amended plans where necessary.

Response:
Refer attached amended Landscape Plan prepared by Anembo. Further detail can be provided as part
of operational works stage.

22.    Provide a table showing the IFD data used for the hydrological modelling and a screenshot
       showing the annual rainfall and evapotranspiration statistics used in the model.

23.    Provide plans showing clearly labelled development envelope and catchment areas and refer
       to the catchment parameters, including areas and impervious fractions within Section 3.3.2.

24.    Include evidence that local and regional flooding has been checked and that a free
       downstream boundary condition is appropriate for the site.

25.    Ensure that the MUSIC modelling parameters follow the MUSIC Modelling Guidelines (the
       Guidelines) (Water by Design 2010), and confirm the runoff pollutant concentrations have
       been generated stochastically.

26.    Ensure that reporting contains enough detail to allow reproduction of the modelling. Please
       refer to the reporting requirements within the Guidelines and ensure that all elements are
       incorporated into the MUSIC component of the SMP.

27.    Provide justification for the saturated hydraulic conductivity being set as 180 (mm/hr) instead
       of the recommended 200 mm/hr in the Guidelines, and the TN Content of Filter Media being
       set at 400 mg/kg.

28.    Provide details of the lining to be used within the Bio-retention area and a typical cross section
       clearly identifying the proposed lining.

29.    Clarification as to how and where the 335 m3 of detention volume will be supplied, in both
       report body and plans. Provide a typical cross section of the detention basin demonstrating
       how the detention volume is provided over and above the extended detention depth/volume
       of the bio-retention system, peak water level and freeboard.

30.    The depth-area relationship and maximum inundation depth should be provided for XP-
       STORM nodes 204 and 205 (assuming these represent the carpark ponding), along with
       statements regarding compliance with QUDM and Council’s maximum inundation depth
       requirements for carparks.

31.    Demonstrate the design meets the requirements of Division 20 – Water Sensitive Design Code
       of the Noosa Plan. The SMP should show assessment against this Design Code.

Response:
Refer attached amended Stormwater Management Plan together with correspondence from Empire
Engineering included within Attachment 3.
