CONSULTING ENGINEERS.

The Lio(18 hour) noise levels have been predicted for the allotments on the subject site that are most
affected by road traffic noise from Beckmans Road. The contour plots of the predicted Lio (18 hour)
noise levels are shown on the figures described below:

° Figure 3- Lio(|8hour) noise contours for the ground floor of residences with no barriers for
the year 2014; and

° Figure 4- Lio(|8hour) noise contours for the first floor of residences with no barriers for the
year 2014;

The predicted Lio(|8hour) noise levels shown on Figure 3 and 4 include +2.5 dB(A) correction for
facade reflection.

The predicted maximum Leg (hour) daytime and night time noise levels for the year 2014 are shown
in Table 5.3.

Daytime is taken to be 6am to |Opm and night time |Opm to 6am.

Table 5.3 shows the road traffic noise level predictions for low set and high set residences on the
subject site without the inclusion of nojse barriers. The predicted noise levels for allotments not
shown in Table 5.3 would be below the recommended noise level criterion of 60 dB(A) Lio(18 hour)
| metre from the building facade.
