Traffic Matter 2 – Impact on Existing Centre Parking Supply
The Noosa Civic Shopping Centre approval (reference 132002.220285.4) requires 1,413 car parks to be
provided (Condition 152), and the existing car parking supply available at the centre is 1,414 spaces.
Therefore, parking supply is currently in excess of the conditioned approval.
With the inclusion of the proposed car wash tenancy, there is a net loss of 14 spaces. This reduces the car
parking supply at the centre to 1,400 spaces, which does not satisfy Condition 152 of the approval that 1,413
spaces should be provided.
Noting that the parking provision of Condition 152 is not met, further investigation has been undertaken to
demonstrate that the proposed car parking supply at the centre will still be sufficient to accommodate the peak
parking demands.
In order to assess the existing Noosa Civic Shopping Centre parking demand, parking survey data used for a
previous traffic study at the centre was utilised. A car parking survey was undertaken by TTM on Thursday 14
February and Saturday 16 February in 2013. The existing car parking demand rates were calculated based
on the car parking occupancy obtained by the survey and the occupied gross lettable area (GLA) of the existing
Noosa Civic at the time of survey. Table 2 summarises the findings of the surveys.
Cardno investigated annual daily door count data from the centre to identify the 90 th percentile busiest shopping
day of the year. The 90th percentile day is chosen as the design parameter for parking demand. This
assessment approach is a standard traffic engineering approach which accounts for all but the busiest time
periods, generally relating to the Christmas and Easter holiday trading periods. Designing for these
occurrences would mean a significant over supply the rest of the year.
For the retail component of the development, the 90th percentile car parking demand based on an annualised
profile was then determined from the 2013 annual pedestrian door count data combined with the car parking
rates determined from the TTM surveys.

The estimated 90th percentile parking demand for the centre is as follows:
           > Thursday: 1,136 spaces
           > Saturday: 944 spaces
As shown on Table 2, the centre currently provides for an additional 278 spaces and 470 spaces for the
Thursday and Saturday trading peak, respectively.
With consideration of the net loss of 14 spaces associated with the proposed car wash, the overall centre will
still provide for an additional 264 spaces and 456 spaces, during the Thursday and Saturday peak periods
respectively.
Therefore, the car wash tenancy is not considered to have a significant impact on the existing parking supply
at Noosa Civic Shopping Centre and the marginally reduced parking supply is considered to be sufficient.
