                 Development Application – Operational Works (Earthworks)

                 Address: 392 Sister Tree Creek Road, Kin Kin

                 Formal Land Reference: Lot 1 on SP241381


                 This correspondence forms part of a Development Application for Operational Works for
                 Engineering Works (Earthworks). This application is associated with a future development for a
                 Dwelling House located at 392 Sister Tree Creek Road, Kin Kin (Lot 1 on SP241381).


                 This Development Application has been lodged on behalf of Megan O’Leary and Rees Maddren.
                 In support of this application please Replace the attached:
                     -    Completed DA Form 1;
                     -    Civil Engineering Plans, prepared by Infinity (Attachment 1);


                 As demonstrated in Figure 1 below the subject site is an irregular shaped lot, contains a lot size
                 of 10.53ha and has undulating terrain. The subject site has historically gained access through 432
                 Sister Tree Creek Road (Lot 4 on RP290098), as the subject site was owned by the person that
                 owned 432 Sister Tree Creek Road. It is noted that no access easement benefiting the subject
                 site is in existence.


                 The subject site was sold in January 2026. As part of the sale, a temporary reciprocal access
                 arrangement was granted by the vendor, which enabled the continued use of the driveway for a
                 period of time (which has now expired).


                 A driveway design was prepared by Infinity (Attachment 1), with the driveway servicing the future
                 dwelling location at the top of the hill (near the existing structures). Figure 2 below provides an
                 extract of the proposal plans, with the figure and provided plans demonstrating the earthworks
                 volume (balanced earthworks volume of 1,323m3). In accordance with Table 5.8.3 (Operational

                 Application (earthworks).

                 Application Assessment
                 In accordance with Table 5.8.3 (Operational Works – Table of Assessment), the application is
                 required to be assessed against the following codes:
                     •    Earthworks Code;
                     •    Water Quality and Drainage Code; and,
                     •    Landslide Hazard Overlay Code.


                 A high-level assessment against the codes is provided below, with further detail provided within
                 the Civil Engineering Plans (Attachment 1). It is also noted that the development has been
                 designed to meet the driveway design requirements for a Dwelling House and therefore further
                 assessment of the associated criteria has not been undertaken.


                 Earthworks Code
                     •    AO1 – The development contains gradients of >1%;
                     •    AO3.1 - AO3.2, AO4.1 – Development earthworks will be undertaken in accordance
                          Council’s standards;
                     •    AO4.2 – Site earthworks can be conditioned to occur between the hours of 7:00am to
                          6:00pm, Monday to Friday and 7:00am to 3:00pm on Saturday;
                     •    AO5.1 – AO5.4 – Vegetation Clearing is not required for the establishment of the driveway;
                     •    AO6.1 – AO6.2 – The site is not located on the Contaminated Land Register. No site import
                          is required;
                     •    PO7 – Haulage conditions can be applied as part of the Development Permit;
                     •    AO8 – All earthworks are proposed to be contained within the subject site;
                     •    AO9 – The extent of cut/fill exceeds 1.5m in depth relative to ground level, with the cut
                          being around 2.35m. It is noted that the proposed development presents the most
                          sensitive design outcome noting the considerable slope of the land and follows the
                          natural topography as far as practicable, whilst maintaining vehicular accessibility.
                          Accordingly, the development achieves compliance with Performance Outcome PO9;
                     •    PO10 – The proposed earthworks do not interfere with any infrastructure;
                     •    PO11 – The proposed earthworks do not interfere with waterways and wetlands;
                     •    AO12.1 – AO12.3, PO13, AO14.1 – AO14.4 – The development does not propose dams or
                          constructed lakes.


                 Water Quality and Drainage Code
                     •    AO1, AO2.1 – AO2.4, AO3.1, AO4.1 – AO4.5, AO5.1 – AO5.3, AO10, AO11.1 – AO11.5, AO13.1
                          – AO13.2 - The earthworks are for a driveway in the Rural Zone, with stormwater runoff
                          from the driveway discharging to landscaped pervious surfaces. Therefore, a stormwater
                          management plan is not required in support of the application;

                     •    AO6.1 – AO6.3, AO7.1, AO8.1 – AO8.3, AO12.1 – AO12.3 – The driveway will not result in
                          stormwater discharging to a waterway, wetland or mapped vegetation area;
                     •    AO14.1 – AO14.5 – The Civil Engineering Plans (Attachment 1) contain Erosion and
                          Sediment Control Detail; and,
                     •    AO15 – AO16 – Not applicable.


                 Landslide Hazard Overlay Code
                 It is noted that whilst a Geotechnical Assessment is yet to be provided, access to the dwelling
                 location cannot avoid mapped landslide hazard areas.


                 Prior to commencement of the construction a Geotechnical Assessment will be provided.




                 This Development Assessment Report has been prepared in support of a Development
                 Application for Operational Works (Earthworks) at 392 Sister Tree Creek Road, Kin Kin (Lot 1 on
                 SP241381).


                 This Development Assessment Report demonstrates compliance with all applicable Assessment
                 Benchmarks of the Noosa Plan 2020 and should be approved by Council, with reasonable and
                 relevant conditions applied only where necessary.
