5          STORMWATER
The stormwater related aspects of the proposed development are detailed in the Stormwater
Management Plan prepared under separate cover.


6          EROSION AND SEDIMENT CONTROL
All erosion and sediment control devices will be designed and implemented in accordance IECA
guidelines and best practice engineering principles. Further detail on Erosion and Sediment Control
techniques and measures is contained within the Stormwater Management Plan prepared under
separate cover. As the site works include basement excavation the sediment laden runoff will be
contained within this basement for treatment and pump out.


7          WATER SUPPLY
Review of the water network from the survey shows the following services:

     •     An existing reticulation water main runs along the internal road verge, to the northern
           boundary of the proposed development.
     •     An existing water connection for the retail development is located to the north west of the
           new retail development.

It is proposed to connect to the existing internal water reticulation system for the proposed
development and utilise the existing connections to the authority mains. Any upgrades to the
existing system will be determined in consultation with the hydraulic consultant and Unitywater
during the detailed design stage of the development.

The existing and proposed water infrastructure in the vicinity of the site is shown on MPN Plan
9954- DA10 attached in Appendix 2.


8          SEWER
Review of the sewer network from survey shows the following:

     •     An existing gravity sewer main exists within the car parking access road of the existing
           retail to the south of the proposed new retail development. It is proposed that a new
           property connection will be constructed from the existing sewer to service the new retail.

The proposed sewer is shown on MPN Plan 9954- DA09 attached in Appendix 2. The depth and
location of the proposed sewer connection will be determined in consultation with the hydraulic
consultant and Unitywater during the detailed design stage of the development.
