Martoo Response to IR

The proposed changes are in response to matters detailed in the information request issued by Council
specifically:

    •     Item 5 which indicates that new development should not be in the Riparian zone. The applicant has
           deleted the two future greenhouses which intruded into this Riparian zone.

    •     Items 6 and 7 which indicate the existing access is not considered suitable and that the access
           must be suitable for the various vehicle types and be in accordance with Council standards. The
           existing site access was not able to comply with relevant standards and therefore access through
           the adjoining property at 271 Lake Macdonald Drive is proposed. Amended application forms are
           included as part of this response.

The applicant contends that the proposed changes to the application are a direct result of Councils
information request and consistent with Section 354 of the SPA and requests that the application be further
assessed.

In response to the items raised in Council information request the applicant has decided to respond to these
items as below:


Item 1:         Provide a flood report for the proposed development.

Applicant’s Response to Item 1: The applicant commissioned Water Technology Consultants to
prepare a flood report for the site – refer attachment B. The report concludes that the impacts are
non-worsening and will not result in any actionable nuisance. The report includes a number of
recommendations including alteration to the greenhouse structure by the provision of lay-down
sheeting to the perimeter of the greenhouse as well as removal of two earthen bunds on the site.


Item 2:         Provide a flood management plan for the development

Applicant’s Response to Item 2: The applicant commissioned Water Technology Consultants to
prepare a flood management plan for the site – refer attachment B.


Item 3:         Provide a preliminary stormwater design plan for the development.

Applicant’s Response to Item 3: The applicant commissioned O2 Environmental to prepare a
stormwater plan for the site – refer attachment C.


Item 4:         Provide a report by suitably qualified Soil and Groundwater specialist to demonstrate
                that environmental harm to soils, groundwater and nutrient loads within Six Mile Creek
                will not result from the proposal

Applicant’s Response to Item 4: The applicant commissioned O2 Environmental to prepare a
stormwater plan (SMP) for the site (refer attachment C) which addresses the lands use and nutrient
loads from the proposal. This SMP concludes that the hydroponic system is a closed system and no
irrigation water can enter the soil profile. Further the SMP indicates that even during storm events the
likelihood of nutrient rich irrigation water being conveyed to the receiving water in minimal due to the
considerable time for flood waters to reach the site as well as measures to be implemented as part of
the flood management plan for the site detailed in Water Technology Consultants report.
