29.7.5.2 Significance of the impact 86.
The impact of the onshore cable route construction on the landscape character of the Rolling Estate Farmlands, Plateau Estate Farmlands, Valley Meadowlands and Estate Sandlands, which occur in Section 3, would be not significant. The wider extents of the LCTs which lie in this section would undergo not significant impacts .
29.7.6 Scenario 2: - Impacts of Onshore Cable Route Construction on Landscape Character on Section 4
87.
Section 4 extends from the settlement of Newbourne to Martlesham Creek and comprises the LCTs of Estate Sandlands and Rolling Estate Sandlands, as well as a very small section of Coastal Levels. The baseline assessment identified a medium sensitivity for the Estate Sandlands, Rolling Estate Sandlands and Coastal Levels. These ratings take into account the inclusion of these LCTs in the AONB.
29.7.6.1 Magnitude of change 88.
The majority of the onshore cable route in this section passes through Estate Sandlands, with short sections through Rolling Estate Sandlands. The differences between these landscapes are subtle, such that little distinction on the ground is discernible. The landform is relatively flat and this, along with the enclosure formed by intermittent trees and hedgerows, means that the influence of the onshore cable route construction would be limited in extents. There would be no HDD construction in this section, with the exception of the river crossing of Martlesham Creek to the north.
89. Much of this landscape comprises cultivated farmland and in this context, the introduction of an open-cut trench would not appear of notable variance with the existing character. Also construction machinery would be used that is similar in scale and type to farm machinery which already forms a part of the baseline character. The linear nature of the process, seen to extend across the landscape, would form an apparent feature, while the impact of storage of materials and spoil heaps would be limited by the use of existing hedgerows for screening.
90.
Embedded mitigation has involved the careful routing of the onshore cable route to ensure that the minimum amount of hedgerows and trees are to be removed. Losses are therefore infrequent and often coincide with existing gaps, or poor quality sections in the hedgerows. While the construction of the trench through agricultural land would give rise to a low magnitude of change, the removal of the hedgerows would give rise to a medium magnitude of change.
91.
The landscapes around Marthlesham Creek are more sensitive owing to their less modified state. Marshy grasses occur on the edge of the creek with riparian
