Attachment 5 - Traffic Impact Assessment Final PTT · 132005.638.06

A review of primary wind directions has been undertaken for data provided by the BoM from 6 July 1994 to
11 August 2023 shows the morning and afternoon wind speed and direction in the northern Sunshine Coast
region. Figure 8 shows that that the annual average wind direction at 9am is from the south, blowing from
this direction around 30% of the time. By 3pm, the annual average data for the same span of years indicates
that the wind blows primarily from the south-east (over 30% of the time) and that a further 20% of the time
the wind blows from the north-east. The majority of dust impacts are likely to felt in areas north and north-
western of the CCA.

All vehicle types currently access the CCA to drop-off concrete, less vehicle types are recorded that
purchase crushed concrete from the Concrete Crushing Area. The majority of vehicle movements to the
CCA are undertaken by rigid vehicles, comprising 44% of vehicles dropping off concrete and 55% of vehicles
making a crushed concrete purchase, refer to Figure 9 and Figure 10. Access to the CCA has been noted to
have previously been an issue at the NRRF with additional weighbridge bypass needing to be constructed to
accommodate the crushing plant, which is too large to pass over a weighbridge. Overall, deposit of concrete
is the fifth most prevalent vehicle movement type based on weighbridge passes of across the NRRF.
