29.2.2 Scenario 1: Potential Impacts of Converter Station Construction on Landscape Character
11.
The baseline assessment of the Ancient Plateau Claylands LCT in which the converter station is located, identified a medium sensitivity as a result of a medium value and a medium to low susceptibility.
12.
Existing woodland blocks around the site would screen much of the construction works from parts of the surrounding landscape, especially to the north-west, west and north-east. From the remaining areas, those aspects of the construction works which are most likely to give rise to impacts on landscape character would include the movement of machinery in and out of the site, the presence of cranes on the site, the presence of the emerging converter station and the use of temporary lighting outwith daylight hours.
13.
The construction would be seen in the context of a site where energy infrastructure is an existing component and where tall structures are a readily apparent feature. The emerging converter station and associated construction activities would, nonetheless, form a notable addition that would influence the character of the immediate surrounding landscape. The scale and mass of the emerging converter station, combined with the activity of the construction works, means that from those part of the LCT within close proximity, the converter station construction would appear as a large scale feature which would be at variance with the scale of the rural landscape. The magnitude of change would be medium to high approximately 800m to the north, as far as Tye Lane and 800m to the east, as far as Miller’s Wood. The magnitude of change would be low in the other directions owing to the screening effect of the East Anglia ONE converter station, existing woodland and the partial screening from the sub-station.
14.
The impact of the converter station construction on the landscape character of the Ancient Plateau Claylands LCT would be significant out to a range of 800m to the north and east, although lasting the short-term duration of the construction phase. Impacts on the remaining parts of the Ancient Plateau Claylands LCT would be not significant.
29.2.3 Scenario 1: Potential Impacts of Converter Station Construction on Visual Amenity 15. An initial assessment to consider the potential impacts of the converter station on the viewpoints is presented in Table 29.1 below. Many of the viewpoints are discounted from the assessment owing to the limited extents to which the East Anglia THREE converter station is visible, either as a result of distance, the screening effect of intervening woodland or the screening effect of the East Anglia ONE
