In the last of our three-part series on noise and planning written by LABC Acoustics, we’re taking a look at policy framework changes and how this impacts residential schemes.
The National Planning Policy Framework (NPPF) has been reviewed, reissued and came into force on 24th July 2018. The new document had implications for the ‘agent of change’ with greater emphasis placed on the protection to music venues. Residential developments bring potential noise sensitive receivers to a source, putting music venues at risk of closure.
The NPPF paragraph 170 states:
“e) preventing new and existing development from contributing to, being put at unacceptable risk from, or being adversely affected by, unacceptable levels of soil, air, water or noise pollution or land instability. Development should, wherever possible, help to improve local environmental conditions such as air and water quality, taking into account relevant information such as river basin management plans;”
The NPPF paragraph 180 states:
“Planning policies and decisions should also ensure that new development is appropriate for its location taking into account the likely effects (including cumulative effects) of pollution on health, living conditions and the natural environment, as well as the potential sensitivity of the site or the wider area to impacts that could arise from the development. In doing so they should:
- a) mitigate and reduce to a minimum potential adverse impacts resulting from noise from new development – and avoid noise giving rise to significant adverse impacts on health and the quality of life;
- b) identify and protect tranquil areas which have remained relatively undisturbed by noise and are prized for their recreational and amenity value for this reason”
The NPPF paragraph 182 states:
“Planning policies and decisions should ensure that new development can be integrated effectively with existing businesses and community facilities (such as places of worship, pubs, music venues and sports clubs). Existing businesses and facilities should not have unreasonable restrictions placed on them as a result of development permitted after they were established. Where the operation of an existing business or community facility could have a significant adverse effect on new development (including changes of use) in its vicinity, the applicant (or ‘agent of change’) should be required to provide suitable mitigation before the development has been completed.”
Extrapolation of this principle to other noise producing sources e.g. industrial or commercial, has an impact on the planning requirements for new residential schemes and Local Authorities have to consider noise impact and the burden of mitigation differently.
In the case of new residential developments, the emphasis has changed in that the polluter (emitter of noise) will not need to pay.
Figure 1: Polluter pays?....not necessarily in the case of noise!
Noise mitigation by residential developers may have to include the usual measures:
- Orientation of sensitive facades away from existing noise emitters
- Noise screening and Barriers
- Façade protection including acoustic glazing, ventilation and building fabric design
- Potentially offering the noise emitter funding to attenuate the noise at source! This could include:
- Localised screening & acoustic enclosures on the emitters site
- Replacing old equipment for new: M&E equipment, air condition units, HVAC plant etc.
- Upgrading existing commercial/industrial building components e.g. single skinned factory buildings upgraded to ensure factory noise is contained within the facility.
