4 Road Traffic Noise Assessment
The road traffic noise model was configured using the CadnaA Version 4.4.145 noise prediction
software (DataKustik, 2013) with algorithms based on those contained in CoRTN (Calculation of Road
Traffic Noise), UK Department of Transport 1988.

Ground absorption is set to G = 0 for roads (internal and external) and paved areas (e.g. hardstand,
carparks, etc.) the remainder of the model domain is set to G = 1. Buildings presented in the site
plan (see Figure 1.2) are included within the model. In addition, surrounding residential buildings
are included within the model with the height taken from site visits and aerial photography.

Topographical information for the site was provided by Noosa Shire Council (NSC), development
layout provided by VerveBD (Drawing: 14004-DA02 Rev E3 dated 16/01/15, 14004-DA11 Rev A dated
10/07/14) and earthwork contours for the proposed design provided by vT Consulting Engineers
(supplied 15/01/15). Figure 4.1 presents the existing topography of the site and the extents of the
model domain.

Floor levels were provided by vT Consulting Engineers (Drawing: 14012-P003 & P004 Rev B dated
9/01/15) as presented in Table 4.1.
