         Revised Civil Design Drawings included in Appendix A. The existing gully pit
         surround and lids are proposed to be replaced in accordance with Noosa Shire
         Council Standard Drawing 9223A and previous gully pit 2/1 has been removed
         / deleted.

EXISTING INFRASTRUCTURE

    •    Items 7-9 – Existing Stormwater Infrastructure

         The existing Council stormwater line located along the western side of the
         property has been identified from available Council records and considered in
         the proposed development layout. This alignment is indicative only and needs
         to be confirmed through locator services during the construction phase.

         The intent of the development is to retain and protect the existing stormwater
         infrastructure in its current alignment. Detailed structural design, footing design
         and temporary works associated with the basement construction will be
         undertaken by the project structural engineer.

         The structural engineer will be required to demonstrate that the development
         does not impose additional loading on the stormwater asset and that the
         proposed footings and excavation works are appropriately designed relative to
         the zone of influence of the existing infrastructure. Required protection and
         support of the infrastructure will need to be designed and certified by the
         structural engineer in accordance with QDC MP1.4 and relevant engineering
         standards.

         If deemed appropriate through the delivery of the work, the stormwater line may
         need to be replaced on the existing alignment.

         The proposed development maintains an open-to-sky setback adjacent to the
         western boundary to preserve future access to the stormwater infrastructure for
         inspection, maintenance and potential replacement works. Accordingly, the
         development is intended to maintain the ongoing function and maintainability of
         the Council asset.


RAINWATER RETENTION

    •    Item 10 – Rainwater Storage for Non-Potable Reuse

         A single 3,000L rainwater tank is proposed for the development, to be use for
         non-potable purposes, being predominantly the irrigation of the on-site
         landscaped areas.

         Compliance is demonstrated against Performance Outcome PO2, which
         requires that development "maximises water efficiency on site by incorporating
