132938-1 Application for a minor change to a development approval (s78-PA) 2018-11-27 · 132008.1128.02

        The southern (retirement living) bioretention basin size and location has been amended from that of
         the existing approval. Additionally, a separate infiltration basin has been added in accordance with
         the Girraween Stormwater Management Plan. Attachment C holds an engineering drawing showing
         these stormwater changes.
        The northern RAC bioretention basin size and location has been amended to use a proprietary
         cartridge system from the treatment of water quality. Additionally, a separate infiltration basin has
         been added in accordance with the Girraween Stormwater Management Plan.
The stormwater solution presented within Attachment C will be adopted moving forward to detailed design
and operational works applications.

  3.10 Bushfire
A Bushfire Technical Note has been prepared by Meridian Urban and is held at Attachment D. The
technical note confirms that the nature of the minor changes proposed continue to comply with or improve
upon the previous bushfire assessments completed by Land Graphics (with the original application in 2008)
and by RPS (with the extension application in 2017).
The minor changes proposed, in relation to bushfire protection include:
        Altered building siting for the residential aged care facility on Lot 6 and minor change to the internal
         layout; and
        Altered product and layout for the retirement facility on Lot 9 including the revised vehicle circulation
         network.
None of the proposed minor changes impact upon the identified asset protection zones or separation buffers
previously noted by RPS in 2017, or other bushfire protection measures which have been identified.
The proposed RAC facility is to be shifted forward towards Grasstree Court to increase the extent of
separation to the narrow vegetated tributary to the rear of the site, between the site and Sunshine Beach
State High School to the north. Whilst this corridor is constrained by virtue of its dimensions and disturbance
/ management, relocation to achieve a separation distance of BAL 29 is now provided. This represents a
substantial improvement from the existing approval.
The revised vehicle circulation network across Lot 9 and servicing the approved retirement facility remains
capable of accommodating emergency fire appliances, as required. Further, it does not present any adverse
or unintended impacts on existing adjoining development to the east from what was previously approved.
As per the current set of approval conditions, a bushfire hazard assessment and management plan is being
prepared and will be submitted to Council for assessment as part of the forthcoming Operational Works
application.

  3.11 Landscaping
Changes to landscaping are purely a result of the proposed changes within the master plan layout. A
Landscape Concept Plan has been prepared by Urbis which is held at Attachment E which reflects this
minor change. The Concept Plan is shown below in Figure 4.
