11. Appendix H - Traffic Impact Assessment

20 Hofmann Drive, Noosaville | Traffic Impact Assessment


9.0 Operational Assessment
9.1 Estimated Traffic Demands
We are of the opinion that the net change in traffic demands as a result of the Proposed Development
will be relatively minor when compared with the Previous Approval and, as such, a detailed traffic
impact assessment (SIDRA) is not warranted in this instance.

Whilst a detailed traffic impact assessment was not undertaken, we quantified the potential change in
traffic demands which may occur as a result of the Proposed Development compared with the Previous
Approval.

As part of the Previous Approval, Council specified traffic generation rates to be adopted for the
assessment for the Home Improvement Store and Retail Business (Type 4) Showroom Uses, as
summarised in Table 9.1. RTA and RMS Guide to Traffic Generating Developments (GTGD) rates have
been adopted for the other proposed onsite uses.

The office uses on site are not expected to generate significant vehicle trips during the weekend. The
food uses on site are expected to provide an ancillary function and therefore not expected to generate
significant vehicle trips during the adjacent road peaks.

The peak hour trip generation of the Previous Approval is summarised in Table 9.2.
