 Minimum Queuing Provisions                -                               1 car (8.4m)                        See note below

The proposed access arrangements generally comply with Council requirements, however the following item
is resolved with a performance solution.

Queuing

The development proposal provides 8.4m queuing (1 car) to the proposed first conflict point.

As detailed further in Section 6, it is expected that the peak vehicle movements into/out of the site will be
17vph during the peak-hour periods. The probability (using the Poisson distribution method) of more than 1
vehicle entering the site at the same time (or say within a 30 second period whilst a car is manoeuvring
in/out of initial parking spaces) and all requiring to queue in advance of the first internal car parking space,
extending back onto Eumundi Noosa Road, is less than 1%. As such, the proposed internal queuing capacity
of 1 vehicle is sufficient to cater for the 99th percentile entry queue of the site and is therefore considered
acceptable.

With respect to entry queue capacity, it is noted that the car parking areas accessed from this driveway will
comprise of low-turnover residential and visitor parking spaces. It is also proposed that the first parking
spaces within the site will be residential and PWD parking, which are expected to only turn over 1-2 times a
day. Therefore, the probability of a car manoeuvring from these spaces at the same time as another car
trying to enter/exit will be low.

Overall, the proposed access arrangements are considered suitable for the proposed development and ‘fit
for purpose’.
