Available site specific data sets for the onshore biological environment are listed in Table 3. These datasets come from work undertaken to date on the onshore cable route which form the basis of the EIA undertaken for East Anglia ONE, and will be used to inform the EIA for East Anglia THREE and East Anglia FOUR. The full list of surveys undertaken is given in Appendix 1 and includes terrestrial and intertidal habitats surveys and protected species surveys.

EAOW believe that the data collected to date covering terrestrial ecology are sufficient for the purposes of EIA for East Anglia THREE and East Anglia FOUR in that they sufficiently characterise the receiving environment. The onshore cable route is identical to East Anglia ONE and works will be within the corridor identified as sufficient for three sets of cables, it is therefore not anticipated that any works would fall outside of the existing study area. This position was discussed and agreed in principle with Natural England in March 2013 (see Appendix 2).
31. Whether the East Anglia THREE and East Anglia FOUR cables are installed in pre- installed ducts or open - trenched, the data characterising the onshore cable route will need to be the same for either option - there will still be a requirement for large plant, temporary roads etc. In many cases the impacts are likely to be similar but with lower magnitudes for cable-pulling (see Appendix 3: Extract from Position Statement on 2013 Associated Development Guidance – Onshore Cable Ducts July 2013 (EAOW, 2013)).
32.
It is intended that as part of the works undertaken for the assessments of East Anglia THREE and East Anglia FOUR the following will be undertaken:
• Walk-over of the onshore cable route (full or partial dependent upon access); Evidence Plan
East Anglia THREE & East Anglia FOUR Offshore Windfarms
