                    Figure 4.3: Ground Level Contours – Proposed Barrier – Facade Reflected




4.6 Assessment of Predictions

Predicted 2024 road traffic noise levels as shown in Table 4.4 meet the TMR external formal open
space criterion of 60 dB(A) LA10(18 hour) free field with the inclusion of the proposed acoustic barrier
as presented in Figure 4.2.

Predicted 2024 road traffic noise levels as shown in Table 4.4 and Figure 4.3 exceed the TMR
external facade criterion (used to protect internal building amenity) of 60 dB(A) L A10(18 hour) at
some cabins facades and caravan spaces with the inclusion of the proposed acoustic barrier as
presented in Figure 4.2. Increasing the barrier height to meet the external cabin facade level seems
unnecessary in this instance as the protection of internal noise level goals for cabins may be
incorporated within the facade as per the QDC MP4.4 noise categories. The QDC MP4.4 noise
categories were for each cabin facade presented in Table 4.4.

As the caravan parking spaces are temporary sensitive receivers, maximum recommended acoustic
barrier height has been used and the development is likely to alter the acoustic background
environment. The acoustic barrier (see Figure 4.2) has been designed to meet the external facade
level of 63 LA10(18 hour) facade reflected.
