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 south
          boundary of the proposed development.
     •    An existing reticulation water main runs along the eastern verge of Hofmann Drive to the
          west of the proposed development.

A new connection from the existing water main located in Hofmann Drive will be constructed. The
size of the proposed water service and exact location 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
8662 -CP.1.01 attached in Appendix 3.


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

     •    An existing rising main collects flow from the Noosa Emporium and Noosa Civic shopping
          centre and conveys sewerage within the easement located to the North-West of the
          development site.
     •    An existing gravity sewer main exists within the car parking access road of the existing
          commercial to the east of the site. It is proposed that a new property connection will be
          constructed from the existing sewer to service the proposed development.

The proposed sewer is shown on MPN Plan 8662-CP.1.01 attached in Appendix 3. 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.
