overhead cables. The constructed features will be new elements in
the AONB, albeit set within the context of existing infrastructure at
GGOWF and the adjacent pylons and overhead wires, and Sizewell
Power Station to the north-east. The proposed landform will screen
lower parts of the substation including security fences, vehicles and
smaller scale equipment, with taller structures such as larger
buildings and lightning rods protruding above it (although the
lightning rods will be minor elements only visible from within close
proximity). At Year 1 (and until it is cloaked in maturing woodland),
the proposed landform will be a new feature but, due to its design
including gentle outside slopes, it will integrate into the existing
landform. Planting will be new and, due to the small size of plants,
will have little effect at this stage.
10.2.3. Within the areas described in paragraph 10.1.4 (including Sizewell
Wents wood, part of Broom Covert, the two arable fields to the south
of Broom Covert and Sizewell Wents (up to Sizewell Gap road), and
the land within which the gantries will be located (up to Sandy
Lane)), the magnitude of effect at Year 1 will be High. This will reduce
to Medium up to a distance of approximately 0.5 to 0.75km to the
north-west, west, south and east, and for a narrow area with potential
visibility of the GGOWF and GWF substation to the north. The
effects on the AONB will be of Major significance, reducing to Major-
Moderate significance within these areas.
10.2.4. The magnitude of effects reduces rapidly to Negligible beyond these
limits due to distance and the buffering effects of existing landform,
vegetation and development. Effects will not extend further
eastwards than approximately 0.3km from the proposed gantries due
to the screening effects of existing trees west of Sizewell Beach car
park. The effects will be Adverse.
10.2.5. The designated area covers 403 square kilometres stretching from
Kessingland in the north to the River Stour in the south. The effects
caused by the proposed GWF substation will be confined to a small
area of the AONB and an area that is already influenced by the
