ENVIRO-ACOUSTIC RESEARCHSCOPING NOISE REPORT – TRANSNET: SWAZI RAIL LINK – DAVEL YARD TO NERSTON RSA ROUTE1.3 PROJECT LOCATIONThe identified route (refer Figure 1-2 for red line) is regarded as favourable due to thelocation Davel in relation with the existing railway lines (yellow line). Thecurrent/proposed route is mostly situated in the Gert Sib<strong>and</strong>e District Municipality.1.4 STUDY AREAThe study area is described in terms of environmental components that may contribute orchange the sound character in the area.1.4.1 TopographyThe terrestrial topography can be described as slightly irregular undulating plains <strong>and</strong>hills.1.4.2 Surrounding L<strong>and</strong> UseThe surrounding area ranges from commercial dryl<strong>and</strong>, forest plantations to cattleranching activities.1.4.3 Roads <strong>and</strong> rail roadsThe most important roads that the rail route current or is proposed to traverse are theN11, N17 <strong>and</strong> R33 National <strong>and</strong> public routes.The existing rail line from Davel to Lothair is indicated in Figure 1-2 as a yellow line.1.4.4 Ground conditions <strong>and</strong> vegetationGround conditions may vary depending on section of rail under investigation (rural orurban). It is assumed that ground conditions could be classified as medium in terms ofacoustics (slightly acoustically absorbent). This specifically relates to the way that theground surface influence the propagation of the sound from the development as thefraction of sound that is reflected from the ground would be influenced as certainfrequencies would be absorbed by the ground surface. Ground conditions will be furtherinvestigated during the Environmental <strong>Noise</strong> Impact Assessment (EIA) phase.1.4.5 Other noise sourcesBesides the mentioned roads there could be a few other significant contributors of noise inthe study area of an industrial nature. Other major ambient noise contributors will beidentified <strong>and</strong> quantified during the ENIA phase.P a g e | 5
