This will be considered if the windfarm is likely to result in the displacement of fishing activities which may impact upon other archaeological receptors not currently affected, and will be considered in the final ES for the proposed East Anglia THREE project.
17.10 Summary
233. The construction, operation and decommissioning phases of the proposed East Anglia THREE project will result in a range of effects upon the marine archaeological and cultural heritage environment. The significance of these effects has been assessed based on best practice, consultation and professional judgement. The effects that have been assessed are anticipated to be reduced to a minor residual significance or are considered to be negligible on the basis of embedded mitigation, as summarised in Table 17.25 and section 17.6 above.
234. Known archaeological receptors are not considered to be subject to significant cumulative impacts on the basis that they should be avoided due to appropriate mitigation. These effects are therefore considered to be negligible. This chapter has also demonstrated that whilst there is the potential for cumulative impacts to occur to potential archaeological receptors, this potential and the significance of any such effects is also considered to be reduced on the basis of the embedded mitigation implemented as part of the proposed East Anglia THREE project as well as the mitigation strategies outlined or anticipated for the existing and future plans and projects reviewed as part of this chapter. Cumulative effects upon potential archaeological receptors are therefore considered to be of minor residual significance. While these effects are essentially adverse, the benefits associated with mitigation geared towards chance discoveries (i.e. the accumulation of archaeologically interpreted geophysical and geotechnical data and an overall contribution to a greater understanding of the offshore archaeological resource) represents a positive cumulative effect that cannot be discounted. However, this is dependent on the demonstration that the studies have been completed to
