Ecological impact.
Comment: The submitted Flora and Fauna Reports demonstrate that the proposed
development will have no significant impact on threatened species,
populations, ecological communities or their habitats.
Impact on the creek.
Comment: The submitted Flora and Fauna Reports demonstrate that the proposed
development will have no significant impact on Woods Creek and
subsequently the Grose River. The development is located
approximately 100m (at its closest point) from Woods Creek which is
considered to be a satisfactory buffer distance to minimise any adverse
impacts, with particular regard to wastewater disposal.
It is considered that with the implementation of appropriate erosion and
sedimentation controls during construction of the development, as well as
the implementation of the proposed stormwater management devices, no
significant adverse impacts on water courses, including Woods Creek
and the Grose River, will result.
Use of equivalent usage in calculations for wastewater generation and
disposal not justified.
Comment: The “Design Review of a Proposed Wastewater Treatment and Effluent
Irrigation System” prepared by Whitehead & Associates Environmental
Consultants P/L advises that design flow to the treatment system is
expected to be 12,000 litres per day based on a maximum occupancy
of 150 persons and a design daily flow allowance of 80L per person and
that this is considered appropriate given that no full scale laundry
facilities are provided and “AAA” rate water saving fixtures will be used
throughout the development.
Insufficient area for required treated effluent irrigation
Comment: The proposed land application area for wastewater disposal is 5,500m 2
which has been assessed as being adequate. This area is
predominantly within the new playing field (oval) and as previously
discussed to ensure the effectiveness of this disposal area, overflow
carparking within this area is not supported.
