Engineering Response to Item 5

5.1
Cross sections of the proposed swales have been included on updated plans which
are included in Appendix A. The portion of the swales that have been disturbed are
shown to require topsoil and seed prior to being lightly compacted.

5.2
Details of the stormwater outlets have been included on updated plans which are
included in Appendix A.

5.3
The proposed works will either create or modify two swales and two stormwater
outlets.

The two swales consist of the main swale through the centre of the site and a
modification to the table drain adjacent to Kinmond Creek Rd.

The main swale is proposed to be stabilised by installing vegetation in the swale.
The vegetation can be sourced from areas that are required to be disturbed as part
of the reshaping project. This process has commenced but is not complete. Figure
5 below demonstrates the process to stabilise the main drainage channel being
implemented.
