ENV56 - HOUSING DEVELOPMENT AFFECTED BY NOISE
In considering proposals for housing development near a source of noise, the Council will consider into which of the four noise exposure categories the proposed site falls taking into account both day and night time noise levels.
Noise considerations will be taken into account when determining planning applications for housing development in sites in Noise Exposure Category B and, where appropriate, conditions will be imposed to ensure an adequate level of protection against noise.
Planning permission will not normally be granted for development of sites in Noise Category C unless exceptionally there are very special circumstances to justify development.
Planning permission will normally be refused for development on sites in Noise Exposure Category D.
