 4.2     Watercourses and Topography
There is a pond and a connecting watercourse, a tributary of Doonella Lake, that runs through Bushland Park
located on the southern side of Gateway Drive. Noosa River is located approximately 1.5km north of the
Development Area.
The Development Area drains from approximately 16.4m AHD at the eastern edge and grading away to 9.6m
AHD at the south-western corner.
The entirety of the Subject Site drains towards Gateway Drive.
Refer to Appendix A for the partial detailed survey for the Development area and contour data from Council’s
online mapping. Additional information has been provided for existing Assets within the road reserve.

 4.3      Existing Land Use and Proposed Development
The lot is an existing Bunnings Warehouse which is proposed to undergo re-development to accommodate more
facilities. The Development Area is comprised entirely of bushland and trees, currently undeveloped and yet to
be cleared.
The proposed development is for a stand alone Bulk Trade Yard with accompanying hardstand and parking.
Refer to Appendix B for the proposed development plans.

 4.4     Existing Stormwater Infrastructure and Lawful Points of Discharge
There is existing underground stormwater infrastructure within Gateway Drive. The existing Bunnings site has an
internal stormwater network consisting of bioretention and detention basin which discharges to the existing
stormwater infrastructure within Gateway Drive.
There is also an existing stormwater pit within the Development Area which connects to the internal stormwater
network within the existing Bunnings site. The Development Area has general fall towards Gateway Drive.

4.5      Lawful Points of Discharge
The existing stormwater infrastructure within the Development Area and Gateway Drive Road reserve is
