15. Design of the convertor station and associated structures would seek to maximise and enhance existing screening and minimize impacts on the Grade II Listed Figeon’s Farmhouse (Figure 25.13). Use of sympathetic design, such as unobtrusive colouring and reduction of glare will diminish visual intrusion of these structures.
16.
East Anglia THREE Limited (EATL) would implement a Written Scheme of Investigation (WSI) during pre-construction and construction phases. This will allow all heritage assets to be identified prior to construction. These assets could then be avoided by microrouting within the working width of the cable corridor, a change in construction methods (such as use of HDD), or ultimately rerouting of the cable route. Where avoidance is not appropriate the WSI would outline a programme for preservation by record. This is considered to be key mitigation and is discussed in further detail in section 25.5.6.
25.3.3 Worst Case 17.
There are two scenarios for the installation of onshore cables for East Anglia THREE: Scenario 1: use of pre-installed ducts; or
Scenario 2: open-trenching for cables for East Anglia THREE and installation of ducts for East Anglia FOUR.
18.
The onshore electrical transmission works will follow the same route in both scenarios, but each scenario will entail different construction methodologies. In addition to the direct working area required for the proposed project construction consolidation sites (CCS) and access roads would also be required. Full details of the development proposals can be found in Chapter 5 Description of the Development.
19.
Considered below are the worst case scenarios with regard to the impact on the archaeological and cultural heritage resource for both scenarios. For each impact, the assessment utilises a worst case. The design parameters that constitute worst case vary depending on the potential impact under consideration and are used as detailed in the table below.
20.
Embedded mitigation strategies within the project design will help to better understand and mitigate impacts on the archaeological and cultural heritage resource.
