8.3                  Existing Noosa Civic Trip Generation
The traffic surveys undertaken were used to determine the existing Noosa Civic trip
generation. Table 12 describes the sites characteristics and resultant trip generation rates for
both the Thursday PM and Saturday midday peak hour periods.

 1.       Number of vehicles entering the subject site at intersections I1 and I2. I4 was closed at the time of surveys.

At the time of undertaking this assessment, the Noosa Civic Access Road / Main Street
roundabout (I4) was impacted by construction activities. As a result, a survey count could not
be obtained to understand the existing traffic demands. Given that this roundabout is newly
constructed, the travel patterns utilising this roundabout are not mature. A site inspection was
conducted on 9 May 2023 to understand the traffic performance of the intersection, and
according to observations, the roundabout typically experiences low traffic demands presently.
To conservatively assess this roundabout, SLR has applied an estimated 120 traffic
movements to the right-turn traffic from the eastern leg and left-turn traffic from the northern
leg as background traffic. It is noted that these additional traffic movements were not
distributed to the external road network and there were no reductions applied to other study
intersections. Importantly, because of this impact, the Hofmann Drive / Noosa Civic Access
Road (I1) was the primary access location for traffic travelling on Eenie Creek Road and Walter
Hay Drive and as a result, the survey data captured is considered conservative.
The assessment traffic volumes are provided at Appendix C.

8.4                  Background Traffic Growth
The HTC 2016 Study has adopted a growth rate of 0.8% per annum from 2015 to 2036 across
the Noosa Shire network. The study forecasted the population projections within the Noosa
Shire according to 2011 census data, which resulted in an average of 0.83% per annum.
Applying this growth rate would be appropriate for the external road network consisting of
Eenie Creek Road, Walter Hay Drive and Eumundi Noosa Road. However, the traffic analysis
presented herein assesses the internal road network for Lot 1 only, consisting of Hofman Drive
and the privately owned road network. As such, traffic growth has not been applied to the
background traffic on these roads. Future developments within the Noosa Business Centre
precinct will contribute to traffic increasing on this internal road network. Therefore, the traffic
expected to be generated by the surrounding future developments, as envisaged by the Noosa
Plan 2020, within the Noosa Business Centre precincts, have been incorporated and is
described in further detail within Section 8.5.

The wider area of the Noosa Business Centre precinct has been considered as part of this
investigation. A summary of the surrounding future developments envisaged by Council’s
