construction), monitoring in other cases during construction.


In the case of the converter station, however, the field evaluation must be undertaken before consent (geophysical survey and trial trenching) because there is less flexibility to preserve important remains in situ (along the cable route, there is flexibility to avoid important remains with the use of directional drilling, etc.). Again, this is consistent with the approach that we have agreed with the developer for EA ONE.


Buried archaeology should be a ‘primary consideration’ during construction.


It should be clear that the use of HDD will not necessarily avoid impact, though it may reduce it’ (Appendix 2).


Initial results of geophysical survey and evaluation undertaken for East Anglia ONE are outlined in Technical Appendix 25.1 and proposals for further evaluation of the convertor site are detailed in a Written Scheme of Investigation (WSI) (Wessex Archaeology 2014).


The impact of HDD on buried archaeological remains is considered in the ‘Potential Impacts During Construction’ section
