Environmental Statement Volume 1 March 2021 Chapter 18 Summary of ES and Mitigation Schedule No Supporting Figures 18. Summary of ES and Mitigation Schedule Introduction 18.1 The purpose of this Chapter is to provide a summary of the outcome of the assessments reported within Technical Chapters 6 – 16, focussing on the following key objectives: • Provide a summary of residual and likely significant effects, the latter of which should inform CC’s decision making process; • Provide a ‘Schedule of Mitigation’, outlining all mitigation committed to; • Conclude on the actions needed to manage environmental effects during construction and operation and establish a suitable mechanism to link to planning conditions, thereby delivering and securing the mitigation; and • Provide a summary of the assessment of cumulative effects. Summary of Residual and Significant Effects 18.2 Each Technical Chapter (Chapters 6 – 16) reports the output of the assessment through residual and likely significant effects, inclusive of a summary. However, the assessment of all residual effects including the likely significant effects across the ES is summarised from both the construction and operation phase in Table 18.1 and Table 18.2, respectively. 18.3 Where effects are significant, this is indicated by (Significant) following the residual effect and is highlighted in red (adverse) or green (beneficial). 18.1 Table 18.1: Summary of Residual and Significant Effects During Construction Technical Chapter Effect Receptor Residual Effect Chapter 6.

Transport and Access in its entirety. No effects were assessed in relation to Chapter 8. Built Heritage during the Construction phase, which is consistent with the approach set out in the EIA Scoping Report (Appendix 2.1) and agreed in the EIA Scoping Opinion (Appendix 2.2). 18.6 8 adverse effects were identified in total, all of which were considered not significant. A further effect, ‘change to the character and amenity of the view’ (detailed in Chapter 7. Townscape and Visual) was assessed in relation to 16 receptors; of which 4 were predicted negligible effects, 5 were predicted minor adverse and not significant effects, and the remaining 7 were predicted moderate adverse and significant effects. 18.7 5 beneficial effects were identified in total, of which 3 are in relation to; habitat loss/degradation/severance/fragmentation; the loss severance and fragmentation of riverine habitat used for resting, foraging or commuting; and the loss of roosting site, potential holts, lay-ups and shelters. All were considered minor beneficial and not significant, due to the proposed protection and creation of habitat (Chapter 9. Biodiversity). Of the two remaining effects, for the topic of Chapter 6. Socio-Economics and Human Health, the creation of direct, indirect and induced employment 18.6 during construction was considered minor beneficial and not significant, whilst the economic productivity generated by the Construction of the Proposed Scheme (measured as Gross Value Added) was considered moderate beneficial and significant. 18.8 Effects caused during the Construction phase for Chapter 14. Daylight, Sunlight and Overshadowing and Chapter 15. Wind Microclimate are represented in the Operational assessments below. 18.7 Table 18.2: Summary of Residual and Significant Effects During Operation Technical Chapter Effect Receptor Residual Effect Chapter 6.
