3.20.1 This policy relates to the impact of aircraft noise, and highlights the importance of ensuring land which is, or is likely to be, subject to aircraft noise disturbance is not used for noise sensitive development such as housing, hospitals or schools. New development which is proposed in areas considered by the Council as potentially at risk from aircraft noise i.e. between 57 and 72 LEQ dB(A) 0700 - 2300 and between 48 and 66 LEQ dB(A) 2300 - 0700 will need to demonstrate that by incorporating noise attenuating measures into their designs an acceptable and sustainable sound environment can be achieved. This will however not be an option for sensitive development such as family-type housing with gardens unless it can be demonstrated that gardens can be used without excessive adverse impact from noise from aircraft. This policy will apply to the conversion of existing buildings to noise sensitive uses as well as the construction of new dwellings.

3.20.2 The Proposals Map No.2 and Inset Map No. 26 shows the areas most likely to be affected by aircraft noise. The contours have been prepared using the INM Model based on predicted air transport movements for the year 2006. The model makes assumptions, including the use of noise preferential routes, and therefore the contours are a reflection of ideal conditions. Developers will be required to take account of these measurements and may be required to submit noise assessments prior to planning applications being determined.

3.20.3 The areas most prone to aircraft noise are immediately adjacent to the Newcastle International Airport, and under the principal arrival/departure air corridors. Aircraft movements have expanded over the last decade and the forecast is that this trend will continue, with a consequential change in the pattern of traffic movements, routes and aircraft types. This will influence the nature and location of the noise contours which will be monitored and reviewed by the Council in conjunction with the Airport from time to time.
