The assessment actually covered two possible landfall locations that were being considered at that time, namely Bawdsey and Felixstowe Ferry. Due to this the offshore cable corridor at the landfall location extended in that assessment between East Lane in the north and Ferry Road, Felixstowe in the south, encompassing the mouth of the River Deben estuary and its associated gravel ebb-tidal delta nearshore bank features called The Knolls. The assessments extended some 1.5km from the shoreline into the nearshore zone.

Subsequent to publication of that report, a decision was made to remove the potential Felixstowe Ferry landfall location from further considerations and the EIA for the proposed East Anglia ONE project thereafter focused on the Bawdsey landfall location only. Notwithstanding this, it remains useful to consider the baseline physical environment across the wider area between East Lane and Felixstowe, and extending 1.5km into the nearshore zone, because any impacts directly within the offshore cable corridor at the Bawdsey landfall location (shown in Figure 7.4.1) could, potentially, affect the shoreline further south, towards and beyond the mouth of the River Deben estuary. This is due to the physical process and sediment transport interactions that exist along this section of coast between Bawdsey and Felixstowe, which are especially governed by a net (generally) southerly longshore drift of sediment along the shore and periodic changes in the form and location of the gravel banks at The Knolls.

The second report (ABPmer 2013) was prepared to address specific comments relating to the baseline physical environment of the offshore cable corridor landfall location that were raised during the Section 56 planning consultation processes to consider the key potential driving factors behind past and ongoing changes to coastal morphology along this stretch of the Suffolk coastline and use this understanding to help infer potential future rates of change over the lifetime of the proposed East Anglia ONE project.

Both of the earlier assessment reports for the baseline physical environment at the offshore cable corridor landfall location for the proposed East Anglia ONE project gave due consideration to the findings of several key scientific research reports, peer-reviewed published papers and management documents, namely:
