At the closest private external living are to Elm Street (Unit 1 Terrace) the ultimate free field traffic noise
level exceeds the 57 dB(A) noise limit by 5.4 dB(A) L A10,18H.

At the next closest private external living area Elm Street (Unit 2 Terrace) the ultimate free field traffic
noise level will be as per Table 4.

Based on the calculations detailed in Tables 3 and 4 for Units 1 to 8 inclusive only the terrace of Unit 1
requires traffic noise control. For the next closest unit, Unit 9 Terrace, the ultimate free field traffic noise
levels will be as per Table 5.
