TRAFFIC GENERATION IMPACT TO THROUGHBOUND TRAFFIC

With respect to the Unit 2 driveway traffic generation impact to throughbound traffic along Avocet
Parade, the following is noted:

N   Avocet Parade is classified as a Local Road, which accommodates at most 1,000 vehicles per day
    in line with the Noosa Plan,

N   Industry practise is that the peak hour traffic volumes are 10% of the daily volumes, and hence it is
    expected that during the AM or PM peak hour period, Avocet Parade would accommodate at
    most 100 throughbound vehicles per hour,

N   Accounting for directional distributions and assuming a 50% / 50% directional split, this
    corresponds to 50 vehicles travelling northbound and 50 vehicles travelling southbound along
    Avocet Parade in the peak hour period. Across the peak hour period, this on average corresponds
    to at most one (1) southbound vehicle along Avocet Parade every 72 seconds,

N   In line with traffic generation guidelines, Unit 2 would generate one (1) vehicle per hour in the
    peak hour period,

N   As such, the likelihood of a vehicle exiting the site (once every hour) at the same time that a
    vehicle travels southbound along Avocet Parade (at most once every 72 seconds) is extremely
    low (approximate 2% likelihood).


COMPLIANCE WITH DRIVEWAYS AND PARKING CODE

Therefore, the above assessment demonstrates the following:

N   The location of the Unit 2 driveway exceeds the minimum vehicle sight distance requirements in
    line with Australian Standards AS2890.1 for a 40 km/hr frontage road speed,

N   The location of the Unit 2 driveway ensures the minimum SSD of 36.0m is able to be
    accommodated along Avocet Parade, such that an unimpeded driver line of sight is provided for a
    southbound vehicle along Avocet Parade to react and brake for a vehicle exiting the Unit 2
    driveway,

N   Due to the low number of throughbound vehicles along Avocet Parade, in conjunction with the
    extremely low traffic generation from the Unit 2 driveway, the likelihood of a vehicle exiting the
    site (once every hour) at the same time that a vehicle travels southbound along Avocet Parade (at
    most once every 72 seconds) is extremely low (approximate 2% likelihood).
