       (b)     Include methods to be undertaken to ensure the protection of the buildings
               and other structures in the case of a flood event; and
       (c)     Include methods to be undertaken to ensure that hazardous material and
               other chemicals are not transported by flood waters in the case of a flood
               event.

Stormwater
3    Provide a preliminary stormwater design plan for the development, prepared by an
     RPEQ. The design must include any necessary stormwater detention or treatment
     features, any features/methods required for erosion and sediment control, and
     indicate the various features required for the construction and operational phases.
     The design must demonstrate compliance with the Queensland State Planning
     Policy’s Water Quality Code and The Noosa Plan, which include details about
     control, detention and treatment.

Soil and Groundwater Protection
Despite low percent concentrations, substantial accumulative loads of nutrients including
Calcium, Potassium, Nitrate, Magnesium and Sulphate are proposed to be discharged into
the soils beneath the greenhouses. The application states that the grasses surrounding the
greenhouse will uptake the nutrients from the unused effluent. However, the application
also comments that the sides of the greenhouse will extend 50cm below the ground. This is
expected to direct waters containing the nutrients away from the rootzone of grasses, to
either leach down to groundwater then migrate to the adjoining creek system or affect the in
situ soil Cation/Anion exchange balances, soil structure and future agricultural potential for
the site. Other concerns associated with the accumulation of 10,000L of nutrient enriched
water per day being discharged, include any impact to soil structure as a result of
groundwater level rises.

4      In lieu of isolating all nutrient enriched effluent from the natural system, a report
       must be provided by a suitably qualified and experienced Soil and Groundwater
       Specialist to demonstrate the capacity of soils beneath the greenhouse to absorb
       the excess nutrient loads and impacts of the effluent on groundwater levels, soil
       structure and nutrient migration to the adjoining Six Mile Creek.

       The Soil and Groundwater Specialist report must demonstrate that environmental
       harm to soils, groundwater and nutrient loads within Six Mile Creek will not result
       from the irrigation and fertilisation proposed, or can be appropriately managed and
       demonstrate that the proposal will comply with Specific Outcome O5 of the
       Agricultural Use Code and Specific Outcome O4 (b) of the Biodiversity Overlay
       Code.

Riparian Buffer
The development of the greenhouses is proposed within the mapped Riparian Buffer Area.
Specific Outcome O5 of the Biodiversity Overlay Code seeks new development is not sited
within the Riparian Buffer Area, as well as avoiding edge effects and incompatible uses
within the buffer.

5      Provide an assessment of the proposal against the provisions of the Biodiversity
       Overlay Code Outcomes, including:
       (a)    Detailing all proposed and existing infrastructure, including drainage
              features, to be located within the mapped Riparian Buffer Area;
       (b)    Provide an assessment of the proposed and existing infrastructure with
              relation to the specific outcomes of the Biodiversity Overlay Code;
