GALLOPER WIND FARM SUBSTATION
9.2.4. Within the areas described in paragraph 9.1.8 (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 during construction 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.
9.2.5. 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.
9.2.6. The designated area covers 403 square kilometres stretching from
Kessingland in the north to the River Stour in the south. The effects
caused by construction of the proposed GWF substation will be
confined to a small area of the AONB and an area that is already
influenced by the presence of GGOWF substation, pylons and
Sizewell Power Station.
9.2.7. Construction of the proposed development with the ‘additional
mitigation area' discussed in section 8.1.1 would lead to similar effects
on the landscape of the AONB as those assessed without the
‘additional mitigation area'.
Suffolk Heritage Coast
9.2.8. The proposed substation lies beyond the boundaries of the Suffolk
Heritage Coast designation. At Year 1 the ZTV indicates limited areas
of intervisibility between the landscape lying within the Suffolk
Heritage Coast and the substation development; this is likely to be
