By path difference calculation an acoustic barrier 2.0 metres high on the Elm Street boundary with a
return along the northern boundary 1.8 metres high will reduce traffic noise levels by more than the
above required values. Figure 6 details the location of these acoustic barriers. These acoustic barriers
must be designed and constructed in accordance with MRTS 15. With respect to Figure 6 the notation
for the corner of each Lot with an acoustic barrier and for each change in direction of a Lot boundary
with an acoustic barrier, the numbers represent base of acoustic barrier/top of acoustic barrier RL AHD.
