1. Terms of Reference

Introduction

1.1. This report comprises the Joint Local Impact Report (LIR) of East Suffolk Council (ESC) and Suffolk County Council (SCC), referred to as “the Councils”. On the 1 April 2019 East Suffolk Council was created by parliamentary order, covering the former districts of Suffolk Coastal District Council and Waveney District Council.

1.2. Each of the main topics are ascribed to a Lead Authority for example SCC is the Lead Authority for Traffic and Transport.

1.3. This LIR has been prepared in accordance with s60(3) of the Planning Act 2008 (as amended) and having regard to the guidance in the Planning Inspectorate’s Advice Note One: Local Impact Reports and the DCLG Guidance for the examination of applications for development consent.

1.4. East Anglia One North Ltd and East Anglia Two Ltd, which are subsidiaries of ScottishPower Renewables (SPR) have submitted two applications for Development Consent Orders (DCO) for two offshore wind farms; East Anglia One North (EA1N) and East Anglia Two (EA2). This LIR relates to both DCO applications and the comments provided within the LIR address the local impacts of both projects unless explicitly stated otherwise.

Scope

1.5. The LIR only relates to onshore impacts of the proposed schemes as they affect the administrative areas of ESC and SCC. This includes the potential impacts of the proposed offshore infrastructure upon areas within the Councils jurisdiction above the mean low water mark including visual and landscape impacts.

1.6. The report specifically describes the impact of Works (described in the Development Consent Orders (DCO); namely: • 800mw wind farm minimum 36km from shore (Lowestoft) – EA1N; • 900mw wind farm minimum 33km from shore () – EA2 • Up to two export cables laid underground landing at Thorpeness and connecting to up to two transition bays for each project; • Up to six electrical cables laid underground between the landfall and the substation location north of with associated cable jointing bays for each project;

• EA1N substation, EA2 substation, National Grid substation and associated grid connection works immediately north of Friston, • Temporary construction consolidation sites for each project and; • Other onshore construction activities and temporary works associated with the above works.

1.7. This LIR does not describe the schemes any further, relying on the Applicants’ descriptions as set out in the DCO application documents.

1.8. Only a brief description of the development area is provided to highlight specific features within the onshore Order Limits. The Applicants’ Environmental Statements (ES) otherwise provide acceptable descriptions.

1.9. The Councils have experience of the DCO process and post consent phases of other windfarm projects. East Anglia One (EA1) windfarm was consented in 2014 and is due to be completed in 2021 and the East Anglia Three (EA3) windfarm was consented in 2017 but has not yet commenced.

1.10. There is no relevant planning history to be described, the Order Limits largely encompass greenfield land other than where they encompass watercourses, woodlands or the public highway.

1.11. The Councils have taken into consideration the responses the Applicants have provided in relation to their Relevant Representation in the drafting of the LIR (Document reference ExA.RR3.D0.V1 - ESC RR-02 and SCC RR-07).

1.12. The Councils continue to engage with the Applicants through the Statement of Common Ground (SoCG) process, with a view to narrowing th
