Residential Planning Noise Assessments

The National Planning Policy Framework (NPPF) (Formerly PPG24)

Residential Noise Planning Assessments used to be controlled under the PPG24 framework, this document has now been replaced by The National Planning Policy Framework (NPPF) published by the Department for Communities and Local Government, this came into force in March 2012.

There are a number of sources of noise that would normally be assessed under this new framework, they include;

  • Road Noise
  • Railway noise
  • Vibration
  • Entertainment Noise
  • Mechanical Noise
  • Industrial Noise

The method of assessment is strictly controlled by a number of British Standards, including but not limited to:

• BS8233:1999 Sound Insulation and Noise Reduction for Buildings – Code of Practice.
• BS4142:1997 Method for rating industrial noise affecting mixed residential and industrial areas.
• The World Health Organisation - Guidelines for Community Noise (1999)
• BS 5228-1:2009 Code of practice for noise and vibration control on construction and open sites - Part 1: Noise.
• BS 5228-2:2009 Code of practice for noise and vibration control on construction and open sites - Part 2: Vibration.
• BS 6742-1:2008 Guide to evaluation of human exposure to vibration in buildings. Part 1: Vibration sources other than blasting.

In essence, the process involves the following steps:

- Measurement of existing Noise Environment about the proposed new dwellings 

- Calculation of internal noise levels within new dwellings

- Comparison against Local Planning Policy

- Provision of Mitigation Advice to demonstrate that Local Planning Policy can be met.

 

In Detail

This new framework sets out the Government’s planning policies for England and how these are expected to be applied.

The intention of the NPPF was to streamline the planning process, make it more localised and less restricted - by reducing regulatory restrictions and focussing on sustainable development.


‘The planning system should contribute to and enhance the natural and local environment by preventing both new and existing development

from contributing to or being put at unacceptable risk from, or being adversely affected by, unacceptable levels of noise pollution.’

Annex 3 of the NPPF states that it replaces Planning Policy Guidance 24 - Planning and Noise although the document contains no specific guidance with regard to acceptable development noise levels (except for mineral operations).

Reference is made within the NPPF to the Noise Policy Statement for England (NPSE), as published by DEFRA in March 2010; which continues the focus of sustainability and aims to: ‘promote good health and a good quality of life through the effective management of noise within the context of

Government policy on sustainable development’.

The implementation of the NPPF and NPSE should mean that noise is properly taken into account at the appropriate time

(for example in planning applications or appeals) where it must be considered alongside other relevant issues.

These documents must be used by Local Authorities in the preparation of their Local and Neighbourhood plans and form material considerations in planning decisions.

The introduction of the NPPF and NPSE has created a void between the policy aims and technical guidance to realise those aims.

Despite the removal of PPG24, there remain a number of existing sources of national and international guidance documents which may assist the acoustic design for both noise sensitive and noise generating development. These can include, but are not limited to,

the following:

• BS8233:1999 Sound Insulation and Noise Reduction for Buildings – Code of Practice.
• BS4142:1997 Method for rating industrial noise affecting mixed residential and industrial areas.
• The World Health Organisation - Guidelines for Community Noise (1999)
• BS 5228-1:2009 Code of practice for noise and vibration control on construction and open sites - Part 1: Noise.
• BS 5228-2:2009 Code of practice for noise and vibration control on construction and open sites - Part 2: Vibration.
• BS 6742-1:2008 Guide to evaluation of human exposure to vibration in buildings. Part 1: Vibration sources other than blasting.
