No significant impacts on all seventeen receptor types in relation to changes in the current regime. However, it was recommended that the potential impact should be considered further to confirm this at EIA stage for individual projects for three receptor groupings (namely ‘Norfolk’ Natura 2000 site, ‘Suffolk’ Natura 2000 site and ‘non-designated sandbanks’) due to some uncertainty regarding the magnitude of changes to the flow speed outside of the East Anglia Zone.
Impacts of moderate significance on the sensitive ‘East Anglia’ coastline, with no significant impacts on the other sixteen receptor types in relation to changes in the sediment transport regime. However, it was recommended that the potential impact should be considered further to confirm this at EIA stage for individual projects for one receptor grouping (namely ‘Norfolk’ Natura 2000 site) due to some uncertainty regarding the importance of different sediment transport pathways to morphological features within this receptor group.
194. The specific features defined within the four receptor groupings mentioned above as requiring further assessment at the EIA stage for individual projects are listed in Table 7.16.
195. This section directly assesses the significance of potential impacts on the wave and/or current and/or sediment transport regimes on the receptor groups of the sensitive ‘East Anglia’ coastline, the ‘Norfolk’ Natura 2000 site, the ‘Suffolk’ Natura 2000 site and the ‘non-designated sandbanks’.
196. It should be noted that the recommendation to include the effects of changes in the wave and current regime on the ‘Norfolk’ and ‘Suffolk’ Natura 2000 sites and the ‘non-designated sandbanks’ was because of their proximity to the western margins of the East Anglia Zone (and, in some instances, their locations within the western- most areas of the East Anglia Zone). The proposed East Anglia THREE project is located further east of these receptor groups at the eastern margin of the East Anglia Zone and this has been taken into consideration in the assessments.
