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.

      Monitoring and Maintenance Programs
Water discharge from the site will adhere to a total suspended solid content of less than 50
milligrams per litre and a pH range of between 6.5 and 8.5 at all times. If the pH of the
flocculated water is not achieved than pH adjustments will be required. This could possibly be
done by a dosing of lime.

Site personnel will inspect all erosion and control measures at least at the following
frequencies:
    • Daily during construction works,
    • Weekly when construction works are not happening,
    • Within 24 hours of expected rain, and
    • Within 18 hours of an impacting rainfall event.

All erosion and sediment control measures that have an order of efficiency below 75% will be
corrected by the end of that working day.


 3. Earthworks

For the purpose of this proposed development earthworks will be conducted for constructing
the new proposed building platforms and roads. Excavation on site will be required for the
building platforms and service trenches. Any excess cut will need to be removed from the site
by the contractor. A geotechnical report will be prepared for the site during the detailed
design stage.


 4. Roadworks

The proposed development fronts onto both Myall Street and Ferrells Road. External
roadworks are proposed for this development in accordance with the traffic impact
assessment report by Pekol Traffic and Transport, project number 13-081.

A new left turn auxiliary deceleration lane (AUL) into the new development is proposed for
traffic travelling from South to North along Myall Street. Dimensions are outlined in the traffic
impact assessment report and to be detailed as per Austroad’s: Guide to Road Design
