The impacts associated with the operation of the proposed scheme have beenpredicted using NoiseMap Server Edition based upon the scheme traffic figures. Theresults of the model have been verified using data obtained from the baseline noiselevel survey carried out at two locations within the study area. Calculations havebeen undertaken at nine representative sensitive receptor locations in the study area.The results indicate that there are no properties within the proposed scheme corridorwhich will be subject to noise level increases of 3 dB or greater, which would bedeemed to be a negligible/minor adverse impact. Therefore mitigation measures tominimise the increase in noise levels associated with the proposed scheme are notrequired.When comparing the Opening year (2011) do minimum with the Design Year (2026)do something is predicted that a number of the sensitive receptors assessed wouldpotentially qualify for insulation under the noise insulation regulations. A further moredetailed NIR assessment may be required to be undertaken at a later stage tospecifically assess qualification for insulation under the NIR.Following a site visit, no sources of vibration were identified in the vicinity of theproposed scheme. Therefore, the need for baseline vibration monitoring and adetailed vibration assessment was deemed unnecessary as the potential for adverseimpacts from vibration during the operational phase is considered to be insignificant.The potential of the proposed scheme to cause vibration that is either significantlyintrusive or capable of giving rise to structural or cosmetic damage is considered tobe unlikely if appropriate working methods and best practice are followed.90
