PO4 Noise-Sensitive Development Policy
In considering proposals for noise-sensitive development, the Local Planning Authority will have particular regard to:
(i) the likely level, tone, duration and regularity of noise exposure and any likely increase in the foreseeable future;
(ii) the existing level of background noise within the locality;
(iii) the extent to which the effects of noise on the proposal can be mitigated through measures such as alterations to layout, provision of noise insulation or restriction of operating hours; and
(iv) the noise exposure category of a site for proposed residential development which is near an existing transport-related noise source.
In all cases, noise sensitive development will only be permitted in locations which are not expected to become subject to unacceptably high levels of noise, or where adequate protection against noise can be achieved by means of planning conditions or planning obligations.
Reasoned justification :
21.12 Noise sensitive development is generally accepted as including housing, hospitals and schools. So far as is possible, such uses should be located away from existing or proposed sources of significant noise. These sources include transport, industrial and commercial uses, construction sites and certain recreational and sporting activities. In the case of hospitals and schools which occupy sizable sites, the impact on noise sensitive buildings and activities may be successfully mitigated through careful attention to design and layout.
21.13 Proposed residential development requires particular scrutiny in relation to noise generating activities. Four Noise Exposure Categories (NECs) have been identified to assist in the assessment of residential proposals near transport-related noise sources, such as road, rail, air or a combination of these with industrial noise sources. Sites within Category A are unlikely to be significantly affected by noise, while noise mitigation measures are likely to be necessary for sites falling within Category B and Category C. Category D sites are unlikely to be acceptable for residential uses.
21.14 Where proximity to transport or mixed noise sources seems likely to be a consideration when assessing a proposal for new residential development, the developer will be required to demonstrate that the site in question falls within noise exposure Category A, Category B or Category C and that adequate protection against noise can be provided through noise mitigation measures.
