service all communal landscaped areas within the development would require approximately 21 kL of stored
water. Therefore we consider the proposal for 24kL adequate for the development.




As a side note, we are of the opinion that the requirement for 3kL of storage per dwelling for a multi level town
house/unit development is not a sustainable design outcome. The total roof area for the development would not
service the volumes suggested resulting in unnecessary infrastructure.

Issue: Erosion and Sediment Control

While it is accepted that detailed erosion and sediment control (ESC) plans can be prepared post-approval and
prior to site works commencing, the plans supplied with the application have significant conceptual issues which
may impact the possibility of acceptable detailed ESC plans being prepared.
Information Request
34.      Provide updated preliminary/conceptual ESC plans which address the following:
         a.       A single Type-D sediment basin is proposed. This is not considered capable of achieving the
                  SPP2017 construction-phase targets and has not been best-practice for some time. A revised
                  strategy is requested incorporating high-efficiency sediment basins.
                  Plans are only provided based on existing levels. Provide additional plans showing controls
                  proposed based on final levels.

Response

The submitted ESC plan is preliminary and conceptual only. Design input is required from the future principal
contractor as to how the site will be managed with regards to construction sequencing and similar matters. On
that basis we request that this information be provided post approval and prior to works commencing.
Issue: Extent of Earthworks
  Council requires additional details of the extent of earthworks proposed to clarify construction impacts and
  address the Acid Sulfate Soils Overlay Code and Earthworks Code.
