Outline 2 • Why are Noise Maps required; • What are Noise Maps and Action Plans; • Timescales; • What will the impact on House Builders be? Reference Settings in Noise Mapping Software – The Effects on Calculation Speed and Accuracy, Hepworth, P. Trow, J. Hii, V. Euronoise 2006
Why are Noise Maps required • EC Green Paper on Future Noise Policy (1996) • Environmental Noise Directive 2002/49/EC • The Environmental Noise (England) Regulations 2006; • English implementation of the END; • Came in to force on 1 st October 2006; • Wales, Scotland Northern Ireland introducing separate Regulations; Reference Settings in Noise Mapping Software – The Effects on Calculation Speed and Accuracy, Hepworth, P.

What are Noise Maps 4 • Cover Road, Rail, Aircraft and Industrial Noise; • Maps for ‘agglomerations’, major roads, major railways and major airports; • 5 year cycle of noise maps; • Definition of agglomeration, major road and major railway changes for 2 nd round of mapping; • Used to provide information for Noise Action Plans.

What are Noise Action Plans? 6 • Noise maps provide data but plans required for action; • Plans required to ‘manage noise issues and effects, including noise reduction if necessary’; • ‘Measures within the plans are at the discretion of the competent authorities’; • Plans required for major roads, major railways, major airports and agglomerations; • Agglomeration plans also to protect quiet areas against an increase in noise; • Competent authorities.

Timescales 7 • Single source Noise Maps by 30 June 2007; • Limit values/criteria for assessment of priorities by 18 July 2007; • Consolidated Noise Maps by 1 October 2007; • Noise Action Plans by 18 July 2008; • Action Plans procedure must include public consultation; • Reviewed every 5 years, or sooner if major development affects noise situation; Reference Settings in Noise Mapping Software – The Effects on Calculation Speed and Accuracy, Hepworth, P. Trow, J. Hii, V. Euronoise 2006
Impact on House Builders 8 • Uses of Noise Maps by General Public; • Uses of Noise Maps by Local Authorities; • Strategic Planning; • Detailed Planning; • Easier for local authorities to assess the need for a detailed noise assessment; Reference Settings in Noise Mapping Software – The Effects on Calculation Speed and Accuracy, Hepworth, P.

Impact on House Builders • Possible opportunities for House Builders; • Contribution towards noise mitigation measures; • Development in areas currently outside guideline values; • Currently no new funding has been announced for mitigation works; • Developer funding could assist existing and proposed housing.

Conclusions • Noise Maps will provide a more informed public and planning authority; • The results will be fed in to the strategic choice of housing sites; • Some sites may become easier to develop because of Noise Action Plans; • Some sites may become easier to develop because of developer funding of mitigation works; • Detailed assessments may require reworking of existing noise maps. peter. hepworth@hepworth-acoustics. co. uk Reference Settings in Noise Mapping Software – The Effects on Calculation Speed and Accuracy, Hepworth, P.
