Information response

Response
Refer attached amended Earthworks Plan. The sheet piling extending beyond the north- and
south- eastern boundary was an error on the original plans and has been removed from the
amended plans.

Issue – Acid Sulfate Soils Management
Council have identified that the proposed development is encumbered by Council’s Acid Sulfate
Soils hazard overlay. The submitted documentation does not include an Acid Sulfate Management
Plan or make reference to a Dewatering Plan.

Information Required
32. Demonstrates through a geotechnical report, if the proposed development triggers assessment
    against the Acid Sulfate Soils Overlay Code of The Noosa Plan 2020. If assessment is
    required, provide a site specific Acid Sulfate Soils Management Plan. The Acid Sulfate Soils
    Management Plan must be prepared by a suitably qualified person (RPEQ – Registered
    Professional Engineer of Queensland).

Response
Refer attached Acid sulfate soil assessment. This report confirms that the proposed development
will not involve disturbance of any soil with potential to contain acid sulfate soil or any soil below an
elevation of 5mAHD and that no specific management measures for acid sulfate soil are required.
No assessment against the Acid Sulfate Soils Overlay Code is triggered.

33. Demonstrate through a geotechnical report, that the proposed development will not encounter
    water during excavations. If the proposed development is likely to encounter water during
    excavation, provide a Dewatering Plan demonstrating how Acid Sulfate affected water
    encountered during excavation will be treated and disposed of. The Dewater Plan must be
    prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of
    Queensland).

Response
Refer attached Acid Sulfate Soil Assessment. This report confirms that the development will have
a negligible risk of affecting groundwater conditions which may impact acid sulfate soils and that
the development may proceed without need for any dewatering management measures.

Issue – Erosion and Sediment Control
The proposed development will alter the existing drainage conditions of the site during
construction. Council is concerned how sediment leaving the site will be controlled and treated and
how erosion of the site and neighbouring properties will be managed.

Information Required
34. Provide a Sediment and Erosion Control plan that demonstrates how the site will control
    contaminates leaving the site without causing erosion damage to the site and neighbouring
    properties. The plan must be prepared by a suitably qualified person (RPEQ – Registered
    Professional Engineer of Queensland) and include, but not be limited to:
    a. a Maintenance Plan that includes:
       i.  maintenance timeframes
      ii.  quantitative or qualitative method of assessing the functionality of each measure
     iii.  review of overall measures
