29. Demonstrate how the proposed incorporation of flood detention within the
    Bioretention basins is consistent with the design principles modelled in
    Section 5.1.2 of the Hyder Consulting Stormwater Management Plan for 139
    Noosa Eumundi Road.

Applicant’s response
The design has been amended to provide for separate bioretention and
detention systems. The outlet arrangement has also been amended to reflect
the change in stormwater strategy on site. Please refer to SK1305 and SK1306 as
part of the Hyder Consulting Response to Information Request provided in
Appendix G.

30. Provide a preliminary drainage plan including survey levels to demonstrate
    that there is adequate depth and fall between the underdrainage level of
    the Bioretention basin as required by the proposal (in terms of required
    detention, extended detention and filter media depths) and the receiving
    stormwater outlet.

Applicant’s response
An amended drainage system is included as part of the Hyder Consulting
Response to Information Request provided in Appendix G.

31. Please provide a preliminary drainage design generally in accordance with
    the design proposed in the Hyder Consulting Stormwater Management Plan
    for 139 Noosa Eumundi Road, as amended in accordance with the
    requirements of this information request, that demonstrates that all
    stormwater will flow to a legal point of discharge and in accordance with the
    design requirements of the Queensland Urban Drainage Manual and in a
    manner that will not adversely impact on other properties, public roads
    and/or the existing drainage conditions in the drainage catchments.

Applicant’s response
Refer to the Hyder Consulting Response to Information Request provided in
Appendix G.

32. The design should include the surveying details and levels of any existing
    receiving stormwater drainage systems, also should indicate the overland
    secondary flowpath/s when the design capacity of proposed stormwater
    drainage system for the developed site is exceeded.

Applicant’s response
An amended drainage system is included as part of the Hyder Consulting
Response to Information Request provided in Appendix G.

33. To ensure the cost of the development is adequately considered, please
    provide confirmation that the applicant is aware that a detailed Erosion and
    Sediment Control Detail Design is required to be submitted with the
    Operational Works approval and to be implemented during the construction
    phase.

Applicant’s response
Confirmed. Refer to the Hyder Consulting Response to Information Request
provided in Appendix G.
