29.3.5.2 Significance of the Impact 58.


The impact of the converter station operation would be significant for the first 15 years and then not significant for the last 10 years of the 25 year consent period as mitigation planting becomes more fully established and partially screens visibility of the converter station.


29.3.6 Scenario 1 – Operation: Viewpoint 12 – PRoW Bramford 3, near Tye House 59.


The viewpoint description, value, susceptibility and sensitivity of this viewpoint are described in relation to the impacts during construction in section 29.2.6. The sensitivity of the view in respect of walkers and residents was found to be medium and in respect of road-users, medium to low.


29.3.6.1 Magnitude of change 60.


East Anglia ONE converter station would be operational and visible as a readily apparent structure. East Anglia THREE converter station would occur to the fore of East Anglia ONE converter station, making it a closer range feature to the viewpoint. While some screening would occur from the intervening woodland, East Anglia THREE converter station would be readily visible in the gap between Bushey Grove and Gobert’s Grove. East Anglia THREE converter station would, however, largely screen East Anglia ONE converter station, such that only part of the breadth of the building would be seen to the right.


61.


The magnitude of change would be medium to high for the first 15 years of the consent as the converter station would form a prominent feature in this view. For the remaining 10 years, the mitigation planting established along the northern side of the converter station would reach a sufficient height to partially screen the building and reduce the magnitude of change to medium.


29.3.6.2 Significance of the Impact 62.


The impact of the converter station operation would be significant for the first 15 years and then not significant for the last 10 years of the 25 year consent period as mitigation planting becomes more fully established and partially screens visibility of the converter station.
