28.3 Scope
28.3.1 Study Area 6.
The Study Area has been identified using the East Anglia THREE site and offshore cable corridor, the onshore electrical transmission works and accesses, to define the search areas for socio-economic data for the proposed East Anglia THREE project.
7. The socio-economic study areas are as follows:
Onshore construction: Drive time catchments of 30 and 45-minutes from Woodbridge (taken as the centre point of the cable route) (Figure 28.1) have been used to provide a locational assessment of onshore construction workers. This is also used to inform Chapter 27 Traffic and Transport.
Offshore construction: the socio-economic assessment will be primarily based on a 90-minute drive time catchment from relevant ports (please see Figures 28.2, 28.3 and 28.4). Sub-area catchments of 30, 45 and 60-minute will provide further context for the assessment and are used to identify potential capacity constraints.
8.
The tourism study area consists of a broad coastal strip (c.10km) from Winterton-on Sea in the north to Walton-on-the-Naze in the south (Figures 28.5 and 28.6). This area covers the main tourism receptors with potential to experience visual effects from the proposed East Anglia THREE project during the construction and decommissioning phases of the project. An additional study area covers a broad corridor (2.5km either side of the onshore cable route from the landfall location to the proposed onshore converter station location (Figures 28.6, 28.7, 28.8 and 28.9). This area is where the majority of potential temporary construction and decommissioning impacts would be anticipated, centred on the alignment of the onshore cable route.
28.3.2 Worst Case 9.
28.3.2.1 Onshore 10.
Socio-economic and tourism and recreation impacts associated with the proposed project are considered at an onshore and offshore level:
There are two scenarios for the installation of onshore cables for the proposed East Anglia THREE project:
Scenario 1: use of pre-installed ducts; or
