− Security fencing.
� An existing communications pole at GGOWF will be re-located
to just outside the southern edge of Sizewell Wents wood. It
comprises a communications device mounted on timber pole.
The existing communications pole is not as tall as existing trees
in the wood.
� Earthworks associated with the substation. The ground will be
excavated to create a maximum platform level of 9mAOD, but
with downward vertical deviation permissible up to 1m (to
8mAOD) to address potential ground variability and to achieve
satisfactory drainage falls on the platform. Note that this LVIA
works on the basis of impacts from a 9m platform level, this
being the ‘worst case’. A profiled landform will be constructed
around the north, west and south sides to provide screening.
The assessment within this LVIA is based on a landform design
presented on Drawing 2890_07H in the Landscape Mitigation
Statement in Appendix 4. There is, however, potential for an
‘additional mitigation area’ to be available to utilise additional
spoil generated during construction of the substation, to create
slacker slopes on the southern side of the landform. The effects
of the proposals with the ‘additional mitigation area’ are also
assessed in this LVIA. The ‘additional mitigation area’ is included
