Item 9(a) – Road safety Audit

The expected traffic generation as a result of the traffic as a result of earthworks is expected to be very low
and a Road Safety Audit does need seem to be warranted.

Item 9(b) – Pavement Impact Assessment

With regard to Pavement Impacts is important to consider the design parameters for the current pavement
based on road hierarchy as outlined in the Noosa Plan. For ‘Distributor’ roads and the majority of ‘Collector’
road types, pavements are designed to have 1x 106 Equivalent Standard Axles (ESA’s) of pavement strength.

It is noted that the Bulk Earthworks scope is to move 1,500m3 of soil daily from the subject site. Typical bulk
haulage trucks are equivalent to a Type 4 heavy vehicle (Austroads) with a gross vehicle mass limit of 12 – 13
tonnes and a carrying capacity of 8 – 10m3 of material. Assuming an average haulage capacity of 10m3, there
would approximately 180 loaded and unloaded vehicle movements from and to the subject site respectively.
The total period of haulage is estimated at 60 days – equivalent to ~100,000m3 total soil removed.

From the Department of Transport and Main Roads (DTMR) Guide to Traffic Impact Assessment Practice
Note: Pavement Impact Assessment the respective truck pavement loadings for these movements are 0.5
ESA’s unloaded and 4.09 ESA’s loaded. Applying these values to the number of movements results in total
pavement loadings to the projected number of trucks movements, results in a total pavement loading of
5,000 ESA’s in the unloaded direction and 41,000 ESA’s in the loaded direction.

Based on the total ESAs on the road network, and given the standard design ESA’s of pavements for the road
hierarchy, the overall pavement impact of truck movements will be less than the 5% threshold as outlined in
DTMR’s documentation. Therefore, the relative pavement impact of truck movements for the Bulk
Earthworks of the subject development will be negligible and no amelioration is required.
