     Construction Phase Management of Sedimentation and Erosion
Existing vegetation from site will be removed in stages as required to reduce the likelihood of
surface erosion. A sediment and siltation fence will be erected around the property boundary
to ensure that sediment is not washed off site and onto adjacent properties or roads. Entry
and exit from the site will be restricted to a single stabilised location to minimise the rise of
onsite transport of silt sediment or mud. It is anticipated that a layer of crushed rock will
provide the necessary stabilisation of the access route. If required a specific bunded wash
down area will be provided for the cleaning of plant before leaving the site and all wash down
waste water will be collected. In the event that debris or sediment leaves the site it will be
cleaned.

    Management of Contaminated Soils Materials
There are no contaminated soils materials fill on the site. The site is not listed on the public
contaminated site’s register.

     Management of Imported Materials
Any material imported to the site including construction materials will be stockpiled in a
location where it cannot contaminate the stormwater system or stormwater runoff.

     Complaint Response
The contractor will erect signage at the entrance to the works with contact information,
including afterhours contact numbers. The contractor will properly deal with all complaints.

      Monitoring and Reporting
All sediment and erosion control devices will be checked daily and after rainfall events by the
construction site supervisor. Defective or full devices will be cleaned and repaired as
required. Regular inspections and maintenance of the storm water system will be carried out
by the property owner. The civil components (structural and erosion) are to be assessed by a
suitably qualified engineer as required.

    Lifecycle cost assessment
There will be no abnormal capital or recurrent costs for the proposed stormwater strategy.

                     h. Flood Zoning

The proposed site is not in a recognised flood zone according to the Noosa Regional Council
River Flood Information Map 10-B50 dated September 2012. See Figure 5.4 below for Flood
map. The map shows that there is no flood zone in close proximity to the proposed site,
therefore flooding issues do not apply to this site.
