 Updated elevation drawings have been provided. Drawing Number DD_A_BS302, shows the elevational
 changes of the Banksia building. The floor plans issued with the change provide a clearer picture of the
 reduction in built form, and are highlighted further in Section 3, Table 2 of the provided Minor Change
 Application Report.



3.0       Issue – Existing Approved Plans

 The application seeks to amend Condition 15 (which references the old approved plans), however does not
 propose to include these plans elsewhere. Some of the existing approved plans (eg relating to the Darwinia
 and Eucalyptus wings) are still relevant and as such need to be maintained, noting previous changes did not
 include the floor plans or elevations of the Darwinia and Eucalyptus Wings

 Information Required:

 •    Provide an amended request to amend Condition 15, stipulating the full list of plans to be retained and
      therefore included in the condition


Response:

 Noted. The proposed condition should read:

      The approved plans are numbered SK-06, 07 issue B SK-8 & 9 Issue A dated 26/01/2000, SD1 (titled ‘Site
      Plan’), SD2, SD3, dated July 2005, SD4 dated May 2005 and DA-1 dated September 2005 DD_A_002.0 Issue R
      dated 14 January 2022, unless otherwise superseded by Condition 46 of this approval.



 Condition 46 Should be updated to reflect the plans outlined in Section 6 below



4.0       Issue – Increase in Fraction Impervious

 The existing development layout was approved with a fraction impervious of 55.4% (13,840m2). The change
 proposes a fraction impervious of 55.1% (13,765m2).

 Given the vintage of the existing development and the significance of the receiving waters, it is unclear if the
 development holistically achieves the acceptable stormwater quality targets outlined in The Noosa Plan 2020
 – Water Quality and Drainage Code.

 You are advised that the documents included as part of the Operational Works application do not include the
 above detail.

 Information Required:

 •    Provide additional detail demonstrating that stormwater runoff from the proposed development causes
      no increase in gross pollutants, total suspended solids, total phosphorous and total nitrogen from the
      existing development. The confirmation must be prepared by a suitably qualified person (RPEQ)
      experienced in stormwater quality and be accompanied by any necessary detail.


Response:

 The proposed minor layout changes have reduced the impervious area from 55.4% to 55.1%, leading to a
 reduction in both stormwater runoff and pollutant generation. As the existing development does not have
 stormwater treatment, this change means there will be no increase in pollutants from the site.

 To ensure compliance with the stormwater quality targets outlined in The Noosa Plan 2020, STP consultants
 have provided an updated assessment (STP24-0253), using a MUSIC model to analyse the impacts for the new
 development area (10,530m²). The results confirm that the development meets the required standards under
 the code.
