Acid sulphate soil testing is typically conducted in areas with reduced levels of less than 5.0m
Australian Height Datum (AHD) as stated in State Planning Policy July 2014. This policy also
states that developments below 20.0m AHD that involve a Material Change of Use or
operational works are required to be assessed against the State Planning Policy July 2014 acid
sulphate soils development objectives. As the lowest point on this site is an approximate level
of RL111.5m, we believe the probability of acid sulphate soil being present is low and
therefore testing would not be necessary.

The requirements for Acid Sulphate Testing will be confirmed by a geotechnical engineer prior
to the detailed design stage of this proposed development.

    Land Disturbing Activities
Important causes/issues of erosion for this site would consist of the following:
    Precipitation and consequent run-off
    Stripping and removal of topsoil
    Removal of fill
    Other earthwork operations
    Heavy vehicle use on site
    Wind erosion

The proposed development is a short construction period which will be programmed so that
the shortest period of time elapses between ground cover removal and restoration.

      Erosion and Sediment Control Measures
Sediment control filter fabric will be securely placed around the perimeter of the construction
site. This will ensure sediment is trapped before being released into the catchment. Refer
Appendix D.

An ESC measure will be provided at any vehicular access points to the site. Construction and
maintenance details are given in Appendix D. A temporary construction entrance will be
provided from Garnet Street for access during construction.

A filter sock sediment trap will be utilized on all downstream stormwater inlets. Refer
Appendix D for construction and maintenance details.

No clearing will be undertaken unless preceded or accompanied by installation of adequate
run-off and sediment control measures, as described above.

Following practical completion of the project a minimum of 70% coverage of all soil with
ground cover (i.e. topsoiling and seeding) will be provided within 30 calendar days.

During the construction phase spraying of water will be used with care to act as a dust
suppression method.
