    (d) a system that demonstrates consistency with the requirements of the approved Stormwater
        Management Plan and as detailed on Approved Drawing BM080320 B10 by VDM Consulting,
        dated 17 November 2011.

Response:
Refer response prepared by Barlow Shelly Consulting Engineers within Attachment 1 and
accompanying Stormwater Plan.

4. Provide a survey plan of the site that includes:
    (a) the property boundaries,
    (b) existing surface levels,
    (c) the location and level of any existing structures of the common property drainage system
    (d) any other services

Response:
Refer accompanying contour and detail survey prepared by KHA Development Managers, which shows
the property boundaries, existing surface levels and the location and level of drainage and other
infrastructure.

5. Provide plans that indicate vehicle paths for the various heavy vehicles accessing the site from the
    north (Rene Street). The plans must also indicate the existing common property road and the
    linemarking.

Response:
It is not intended that heavy vehicles will enter the site and will remain within the common property
driveway. The common property driveway has been designed to accommodate articulated vehicle
movements. Use of the common property driveway for heavy vehicles was accepted and approved
with previous material change of use approvals (2007/1841 & 2009/1323) over the community titles
scheme land for Noosa Metro Innovation Park, with individual lots only accommodating access for
small rigid vehicles.

6. Provide plans that indicate:
    (a) The loading bay as described in The Driveways and Carparking Code - Specific Outcomes O7
        and O8. The loading bay must be located such that it does not impede access to the other car
        spaces
    (b) Indicate on the plans a dedicated turning area or demonstrate how a vehicle would be
        manoeuvre on site and exit in a forward gear if all of the car spaces are occupied.

Response:
Refer amended proposal plans prepared by Building Suncoast Green which provide for a dedicated
turning area. SRV access/loading is provided within the warehouse building, with sufficient
manoeuvring width provided within the driveway aisle. This SRV access/loading arrangement is
consistent with that approved under previous material change of use approvals (2007/1841 &
2009/1323) over the community titles scheme land for Noosa Metro Innovation Park.

7. Provide amended plans that include:
    (a) the proposed finished levels of the building and hardstand areas
    (b) the extent of any necessary earthworks and retaining structures

Response:
Refer amended proposal plans prepared by Building Suncoast Green which indicate the proposed
finished levels of the site and intent for retaining along the north-eastern boundary. Further details of
site fill and retaining will be addressed as part of a subsequent operational works application.

Dear Scott

RE:     PROPOSED COMMERCIAL/INDUSTRIAL DEVELOPMENT
        AT LOT 11 RENE STREET, NOOSAVILLE
        RESPONSE TO COUNCIL INFORMATION REQUEST
        (Ref: MCU15/0005)




Please find enclosed our partial response to Item 3 of Noosa Council’s Information
Request (reference: MCU15/0005) dated 24/02/2015 for inclusion in your combined
response. The issues refer to the subdivision development on Lot 11 SP230643 at
11/100 Rene Street, Noosaville.


Issue #3: Stormwater
The higher order approval applicable to the original subdivision is
MCU2007/1841.Condition 59 required a revised Stormwater Management Plan to be
provided with the subsequent Operational Works approval to achieve pollutant reduction
targets necessary to protect downstream ecology. This Stormwater Management Plan
was accepted and approved in the subsequent Operational Works Approval
OPW2009/42. Approved Drawing BM080320 B10 by VDM Consulting, dated 17
November 2011 shows the subject allotment required a bioretention area of 9.0m2 along
with a rainwater harvesting tank to achieve consistency with the approved Stormwater
Management Plan.
The current proposal states that water quality treatment is not required due to the size of
the site. It is acknowledged that the State Planning Provisions only require water quality
treatment devices on allotments that exceed 2500m2. However, this management
detailed in the State Planning Policy is for developments that are already zoned for
particular development. At the time the subdivision and use was approved on this
particular allotment, it was on the provision that the downstream ecology would not be
impacted. The original applicant demonstrated the downstream ecology would not be
impacted by water quality changes via implementation of stormwater quality treatments
detailed on Approved Drawing BM080320 B10 by VDM Consulting, dated 17 November
2011.


1259-01 KHA Development Managers                                                          1

There are also concerns with the location of the existing stormwater drainage structures
and the proposed “built to boundary” wall and its associated foundations. The
stormwater pit located about mid-way along the southern site boundary appears to be
either straddling the boundary or be very close to the boundary line.

Information Required
Provide a preliminary stormwater disposal design for the proposed development. The
design must include:
    a) Collection and treatment of the runoff from the building and hardstand areas
    b) A treatment area that is in generally accordance with the higher order approval
       and modified, where necessary, to cater for the proposed development.
    c) The connection points to the existing common property drainage system
    d) A system that demonstrates consistency with the requirements of the approved
       Stormwater Management Plan and as detailed on Approved Drawing BM080320
       B10 by VDM Consulting, dated 17 November 2011.

Response:
The development layout has been updated with a conceptual stormwater quality
management system to reflect the requested information above.
   a) Please refer to the attached annotated document for information on the size,
      position, and levels of the proposed bioretention basin.
   b) The treatment area of the proposed basin is approx. 9m2 which is in accordance
      with the approved stormwater Management Plan by VDM Consulting for the
      higher order development. It is noted that the approved VDM stormwater quality
      management plan had achieved superseded treatment targets of 90% reduction
      in concentration of TSS, 70% reduction in concentration of TP, and 50%
      reduction in concentration of TN. Current legislation of stormwater pollutant
      removal targets requires load-based (kg/yr) reductions of 80% TSS, 60% TP and
      45% TN. In appendix B of the Stormwater Management plan for the higher order
      development, the load based reductions over the whole development are listed
      as 98.5% TSS, 78.5%TP, and 50% TN. Therefore, the greater development is
      performing above the current legislated requirements in terms of quality of
      frequent storm runoff. The proposed bioretention basin of 9m2 (in accordance
      with the VDM report) treats approx. 85% of the Lot 11 development site.
   c) The bulk of the development is connected to the higher order development
      drainage system via the outflow from the proposed bioretention basin. The small
      portion of site runoff not flowing to the bioretention basin will be received via the
      grated inlet of the field inlet pit in the eastern site corner.
   d) The proposed bioretention system is compliant in area with the approved VDM
      drawing BM080320- B10, the conditions (in the change to existing approval (ref:
      142009.42.2) dated 10-01-2011, and the Approved Stormwater Quality
      Management Plan by VDM Consulting (Ref: M3048). Please refer to the
      attached drawing for details.
