29.6 Scenario 2: Impacts of Landfall Location Construction 34.
The construction of the landfall location involves the installation of a cable connecting the cable from the seabed with the cable on the land. HDD construction would be used and would require a Construction Consolidation Site and drilling rig located in the farmland adjacent to the cliffs. Construction works to connect the offshore cable route into the landfall location would take place offshore. In the farmland, between the cliff top and Ferry Road, four permanent transition pits would be constructed, each 5m x 10m x 5m deep, buried below ground surface and accessed at surface by a manhole cover or kiosk. Access may be required from the farmland down onto the beach to enable related activities during the drilling of the HDD’s, the pulling of cable ducts and the subsequent installation of the export cables. An access route would be agreed with Natural England and the Environment Agency selecting a location and profile that would minimise the potential impacts.
29.6.1 Scenario 2: Impacts of Landfall Location Construction on Physical Elements 35. HDD construction would be used to construct the onshore cable route at the landfall location. This would ensure that there would be no disturbance to the beach, cliff and cliff path. Elements of the physical landscape may, however, be affected by the construction of an access route for construction machinery onto the beach, should this be required. The impact on each of these elements is assessed below.
36.
The sensitivity of the beach is medium to low as it mainly comprises shingle which is easy to remove and replace during the construction works. The sensitivity of the farmland is low as the land is already modified through agricultural practices, such that the vegetation cover is already temporary. The sensitivity of the cliff, and the cliff top where the Suffolk Coast Path is routed, is medium to high, as this landscape element is more sensitive and difficult to restore, although signs of erosion are already evident and development has previously taken place in this location.
37.
The magnitude of change on the cliffs as a result of the landfall location construction would be medium as the provision of access on and off the beach would cause disturbance to the vegetation on the cliffs, as well as the structure of the cliffs. There would also be the construction of transition pits in the adjacent agricultural
