Jetty Non Technical Summary - EDF Hinkley Point

7.5.16 Impacts on views from the east, including farms located within the Wick Moor landscape
character area would be of minor to moderate adverse significance depending on the
sensitivity of the receptor. These views would be potentially affected by the light pollution
associated with the (unmitigated) jetty development. The majority of views, however,
would not be affected due to screening provided by the existing Hinkley Point Power
Station Complex, topography and vegetation. The only visual impact of major adverse
significance would occur at Pixies Mound due to the very short distance from the site and
medium magnitude of impact on this highly sensitive receptor.
7.5.17 The impact of the unmitigated jetty development and associated lighting on the elevated
areas of the Quantock Hills AONB or Mendip Hills AONB would be of moderate adverse
significance. The main source of this impact would be light pollution. A similar adverse
impact could be also experienced from Brean Down, Fairfield House, Stockland Bristol
and other local viewpoints up to 3km from the application site. Although the majority of
these viewpoints would have limited views of the jetty development’s construction and
operation, adverse impacts would occur due to potential light pollution.
7.5.18 The unmitigated dismantling and restoration phase of the jetty development or, if
required, removal and reinstatement phase, would include the dismantling or removal of
all built elements created during the construction phase and restoration or reinstatement
of the existing landform and vegetation.
7.5.19 The short-term visual impacts associated with the dismantling or, if required, removal of
the jetty development would be largely the same as the impacts associated with
construction and operation. The impact caused by the dismantling or, if required, removal
of built form, earthworks and lighting, as well as activities associated with the replanting
of the vegetation lost during construction within the site, would cause the same
magnitude of visual impacts and remain adverse in nature.
7.5.20 Following the short-term impact associated with the dismantling or, if required, removal of
the jetty, long-term impacts would occur due to the restoration or, if required,
reinstatement of the existing landscape features within the application site, including
topography and vegetation. The impact on all visual receptors following restoration or, if
required reinstatement would be of negligible significance in the long-term.
Mitigation
7.5.21 Following the identification of the potential landscape and visual impacts on the receptors
identified in the baseline study, measures have been proposed to mitigate these effects
during construction, operation, dismantling and restoration and, if required, removal and
reinstatement phases of the jetty development.
7.5.22 The mitigation measures are proposed within the site boundary and, where possible,
within the wider Hinkley Point C development site. To mitigate adverse impacts on the
Coastal Eastern Lowlands area and Fairfield House, and to protect land on the estate
(which is of outstanding scenic interest) from landscape and visual impacts during all
phases of the jetty development, Fairfield Estate (supported by EDF Energy and in
consultation with English Heritage and Natural England) is in the process of preparing
proposals for off site planting to augment the on site mitigation (see Figure 11).
