would be discernible at this distance, if they are not screened. The
proposed landform and woodland will form new elements on the
skyline, occupying a large width of the view. The proposed woodland
will extend from Sizewell Wents to the left of the view. The proposed
woodland will largely screen the existing pylon towers and wires that
currently span the horizon line.
Magnitude and Significance of Effect
11.3.32. The almost complete screening of the proposed substation compound
and existing pylons by foreground vegetation go some way to
moderating the magnitude of effect of the proposed substation. The
principal effect will be change to a more wooded skyline. The toe of
the proposed landform will be visible, integrating with the landform
and vegetation in Broom Covert. The magnitude of effect is judged to
be High to Medium due to the scale of the change on the skyline. The
sensitivity of receptors represented by this viewpoint is High. The
significance of effect at Year 15 is assessed as Major-Moderate. On
balance it is considered that the changes will be Neutral as the
existing pylons will be screened but it is possible that some substation
structures will be visible above trees. In the longer term, as trees
continue to grow, it is likely that all substation structures will become
screened.
11.3.33. The ‘additional mitigation area’ will not be visible from this
viewpoint. Implementation of the proposed development with the
‘additional mitigation area’ will not change the effects assessed above.
Viewpoint 3 – Sizewell Beach Car Park
Proposed View
11.3.34. The trees lying to the west of the viewpoint will screen the proposed
substation. It might just be possible to glimpse the gantries through
the trees in winter but it is unlikely to be a noticeable change to the
view. Mitigation planting will not be visible.
