29.3.4.1 Magnitude of change 52.
It is assumed East Anglia ONE converter station would be operational and visible as a long and low roofline seen above the intervening tree cover. East Anglia THREE converter station would occur to the fore of East Anglia ONE converter station, with the alignment between the two similar, such that the buildings would typically be seen as one mass, with East Anglia THREE converter station, forming a minor increase in the extents of development. Existing tree cover would screen the lower parts of both buildings, such that only the roof structures would be visible above the tree tops.
53. While mitigation planting would take 25 years to reach approximately 12 metres, in the interim it would bolster the existing tree planting, giving the screening effect more depth and substance. Taking all these factors into account, the magnitude of change on this view would be medium to low.
29.3.4.2 Significance of the Impact 54.
The impact of the East Anglia THREE converter station on the view would be not significant, owing principally to the screening effect of the intervening tree cover, the existing influence of development in this view and the comparatively small addition which the additional converter station will make.
29.3.5 Scenario 1 – Operation: Viewpoint 11 - PRoW Bramford 2, near Bullen Farm 55.
The viewpoint description, value, susceptibility and sensitivity of this viewpoint are described in relation to the impacts during construction in section 29.2.5. The sensitivity of the view in respect of walkers was found to be medium.
29.3.5.1 Magnitude of change 56.
East Anglia ONE converter station would be operational and from this close range, visible as a large scale double shed. East Anglia THREE converter station would occur to the fore of East Anglia ONE converter station, and would be readily visible from this viewpoint and sections of the PRoW in either direction. East Anglia THREE converter station aligns closely with East Anglia ONE converter station, such that overall, there is only a minor increase in the extents of development. The closer range of East Anglia THREE converter station would, however, make it appear larger in scale and the additional breadth of the combined developments would be evident.
57.
The magnitude of change from this viewpoint would be medium to high. Mitigation planting along the eastern side of East Anglia THREE converter station would gradually reduce the magnitude of change from medium to high to medium to low as it grows to screen the converter station up towards the roof structure.
