    •   Ensuring construction-phase erosion and sediment control in accordance with IECA Best Practice
        guidelines

These measures align with the intent of the SPP to protect environmental values and apply water-sensitive urban
design principles where practicable.

Regulatory Compliance and Sustainable Outcomes

The proposed stormwater management measures comply with the requirements of Noosa Shire Council, QUDM
and State Planning Policy guidance, ensuring:

    •   No adverse impact on surrounding properties or downstream drainage systems

    •   Effective attenuation of peak flows through the proposed detention tank

    •   Improved stormwater quality outcomes through best-practice measures

    •   A hydraulically neutral post-development condition

Overall, the stormwater management strategy demonstrates that the development can proceed without adverse
stormwater impacts and with appropriate safeguards for downstream water quality and flood behaviour. The
SWMP supports the development application by confirming that stormwater has been appropriately assessed and
managed in accordance with recognised engineering and environmental standards.



Final Recommendations

To support the effective implementation and long-term operation of the proposed stormwater management
system, the following recommendations are made:

    •   Final detailed engineering design should verify the detention tank, outlet structure and internal pipe
        network to ensure compliance with QUDM and Council requirements for all relevant design storm events.

    •   Routine inspection and maintenance of the detention tank, including removal of sediment build-up, and
        inspection of the outlet structure, should be undertaken to maintain system performance over time.

    •   Post-construction review of the stormwater infrastructure should be completed to confirm that as-
        constructed conditions match the approved design and that the system is performing in accordance with
        Council standards.

By implementing these recommendations, the development will maintain effective stormwater performance, and
ensure protection of downstream properties, infrastructure and receiving waterways.
