8. If the basement slab does not entirely seal the basement, provide additional detail
    demonstrating how any groundwater seepage into the basement will be controlled,
    collected and released without the use of a stormwater pump. The detail must be
    prepared by a suitably qualified person (RPEQ – Registered Professional Engineer
    of Queensland).
9. Provide an Acid Sulfate Soils Management Plan, which includes a Dewatering Plan,
    demonstrating how Acid Sulfate affected soils and water encountered during
    excavation will be treated and disposed of or reused. The additional plans must be
    prepared by a suitably qualified person (RPEQ – Registered Professional Engineer
    of Queensland) and adhere to the recommendations made in Appendix E of Pacific
    Geotech Consulting’s ACID SULFATE SOIL REPORT (PG-9236) dated November
    2022.
10. Provide an amended Earthworks Plan that incorporates the recommendations made
    in Appendix E of Pacific Geotech Consulting’s ACID SULFATE SOIL REPORT (PG-
    9236) dated November 2022. The amended plan must be prepared by a suitably
    qualified person (RPEQ – Registered Professional Engineer of Queensland) and
    include, but not be limited to:
        a. a temporary stockpile and treatment area for Acid Sulfate Soils;
        b. a suitably sized drain or retention basin to collect drainage from the
             treatment area; and
        c. a temporary stockpile for treated soils for the purpose of general reuse or
             removal.
11. Provide additional detailing on the proposed concrete piling within the development.
    The detailing must be prepared by a suitably qualified person and include, but not
    be limited to:
        a. standard details of the concrete piling;
        b. anchoring points (noting that all anchoring points, both above and below
             ground, both temporary and permanent, must be contained entirely within
             the subject site unless written permission from the respective landowner(s)
             is provided to Council); and
        c. demonstrate the structural integrity of the surrounding lots (Lot 128 & 134
             Gympie Terrace and Chaplain Park, Mill Street) will not be undermined as
             result of the excavation.
12. Provide additional detail demonstrating how the proposed pool excavation will
    occur, noting that owners’ consent will be required if the contractor wishes to utilise
    the western property (128 Gympie Terrace) or northern park (Chaplain Park, Mill
    Street) in any capacity.
13. Provide additional information demonstrating the effects the water table and existing
    natural constraints will have on the basements’ waterproofing ability to avoid
    seepage. The additional information must be certified by a suitably qualified person
    (RPEQ – Registered Professional Engineer of Queensland).
14. Provide sufficient detail to demonstrate that the development achieves compliance
    with The Noosa Plan 2020 – Sustainable Building Design Code. The detail must be
    prepared by a suitably qualified person (RPEQ – Registered Professional Engineer
    of Queensland). Any proposed reuse & attenuation tanks must be certified by a
    geotechnical engineer where located below the water table to ensure they are
    adequately secured and unable to move due to the natural water table.
15. Provide additional detail on the proposed development’s internal drainage system.
    The detail must be prepared by a suitably qualified person (RPEQ – Registered
    Professional Engineer of Queensland) and include, but not be limited to:
        a. the surface levels, invert levels, lengths and grades of all internal stormwater
             infrastructure; and
        b. a longitudinal section of each stormwater ‘line’;
        c. indicate where the roof downpipes connect to the proposed stormwater
             system; and
        d. amendments demonstrating compliance with the Sustainable Building
             Design Code (Item 8.);
16. Provide additional detail demonstrating where the ‘150 grated drain’ will discharge
    to.
17. Provide additional detail and comment demonstrating how the proposed stormwater
    system and associated infrastructure will function during, up to and including, 1%
    AEP events (including flood events) and when experiencing an average annual
    rainfall increase of 20% by the year 2100. The additional detail and comment must
    be prepared by a suitably qualified person (RPEQ – Registered Professional
                                                                               Page 5 of 6
