of cable crossings, direct impacts to known receptors should be avoided due to appropriate mitigation.
219. Significant cumulative impacts are restricted to direct impacts upon the potential archaeological resource from the East Anglia THREE site and offshore cable corridor with other plans and projects across the wider region that will have an indirect impact upon receptors within the East Anglia THREE site and the offshore cable corridor areas. This is particularly likely to be the case where potential receptors are within the East Anglia THREE site and offshore cable corridor as well as being in close proximity to other plans and projects, as it is often the case that indirect impacts are heightened near-field. Cumulative impacts may therefore occur to the potential archaeological resource where the offshore cable corridor overlaps other plans and projects (e.g. the cable crossings with Greater Gabbard). However, the significance of cumulative impacts upon potential receptors is considered to be reduced on the basis that mitigation strategies (e.g. implementation of micro siting) have been or are likely to be developed for all of the planned and existing projects listed above
220. Significant cumulative impacts to potential archaeological receptors within the East Anglia Zonemay occur as a result of multiple unavoidable impacts to potential archaeological receptors across a region as a result of the proposed and existing developments listed above.
221. Individual sites at specific locations are not only archaeological receptors in themselves; they are also part of the archaeological resource as a body of data and as collective heritage. As such, it is necessary to consider how a number of impacts on the specific aspect of the collective heritage may result in a significant cumulative impact.
222. Potential archaeological receptors are equally as likely to be found outside the Study Area as within it. For example, although palaeolandscapes are largely unmapped, a number of features identified in the palaeogeographic assessment are cut by the boundary of the East Anglia THREE site (see Figures 17.2 and 17.3). As such, palaeogeographic features of archaeological potential may extend beyond the bounds of the Study Area. Similarly, records of documented losses and regional maritime activities signify that there is the potential for maritime and aviation receptors to exist beyond the bounds of the project.
223. If potential archaeological receptors are present, and if they are directly impacted by other projects, there would be an indirect impact upon the archaeological resource throughout the region and hence, upon the receptors Study Area. However, while the cumulative effect of these direct impacts would be significant on a regional scale,
