B6.1.2 Noise management
Code: C6.4
Where a noise barrier is required as part of acoustic mitigation measures, and is visible from the street, its appearance must be softened through the inclusion of a landscape buffer, which contributes positively to the streetscape. This buffer must:
provide safe and ongoing access for the maintenance of the noise barrier, and avoiding any negative impact on its structure
be a minimum of 2 metre wide, noting that the final width of the acoustic barrier will be determined by its superficial mass of greater than 10 kilograms per m²
include layered planting with species selected for seasonal interest, visual screening and compatibility with the local context
clearly define responsibility for long-term maintenance of the buffer and secure this through appropriate management arrangements
Exception: The inclusion of a landscape buffer may be reduced or omitted where it can be demonstrated that its inclusion would reduce the effectiveness of the acoustic mitigation (for example by requiring the barrier to be positioned further from the noise source).
