21 LANDSCAPE AND VISUAL AMENITY 21.1 Introduction 21.1.1 This Chapter of the ES provides an assessment of the potential landscape and visual impacts associated with the construction, operation, dismantling and restoration of the proposed jetty development and, if required, its removal and reinstatement. Mitigation measures are proposed, where appropriate, to manage any potential adverse impacts that are assessed to be of significance. 21.1.2 The assessment has been undertaken through a combination of review of available desk top information on landscape character and sensitivities, consultation with stakeholders, field survey, the use of 3d modelling techniques and the establishment of a number of representative viewpoints around the application site, from which the visual impact of the jetty development has been reliably assessed. a) Scope of Assessment Scoping 21.1.3 The intended scope of the EIA was assessed in the ‘Hinkley Point C Preliminary Works Development: Temporary Jetty Environmental Scoping Report’ issued to the Marine Management Organisation (MMO) in March 2010 (Ref 21.1). 21.1.4 The report stated that the proposed jetty development would have the potential to change the character and appearance of the coastline and cliff top, i.e. cause landscape and visual effects. It would also locally alter the character of the wide and open seascape as viewed from the shore. The report anticipated that the jetty would be highly visible from the coastal footpath and the coastal frontage (e.g. Lilstock) to the west and from the east the jetty would appear in alignment with the coastline. 21.1.5 It was also noted that any change in landscape character and visual effects associated with the jetty would be of a temporary nature because it would only be needed during the construction of Hinkley Point C, after which it would be dismantled and the site restored. The scoping report noted that the landscape and visual effects of the proposed jetty would be assessed using landscape and visual impact assessment (LVIA) methodology based on the guidelines produced by the Landscape Institute and the Institute of Environmental Management and Assessment (Ref 21.2). 21.1.6 In response to the scoping report, a formal Scoping Opinion was issued by the MMO in June 2010 (Ref 21.3) (see Appendix 5-1, Volume 4). As part of the scoping process, the MMO consulted with all relevant statutory authorities, and responses were obtained from the following: • Natural England; • Countryside Council for Wales (CCW); • Environment Agency; • Sedgemoor District Council; • Somerset County Council; • West Somerset Council; • Ministry of Defence; • Highways Agency; • English Heritage; and • Network Rail. Hinkley Point C Preliminary Works 21 - 1 Environmental Statement Temporary Jetty Development November 2010 21.1.7 In relation to the LVIA, the following comments were made: • Zone of Theoretical Visibility (ZTV) map should be included in the ES; • illustrative material describing the relative locations and proximities of surrounding features should be provided; • the assessment should conform with the Guidelines for Landscape and Visual Assessment jointly produced by the Landscape Institute and the Institute of Environmental Management and Assessment; • details of lighting and associated mitigation should be provided; • due consideration should be given to the impacts of lighting on the Special Areas of Conservation (SAC), Special Protection Areas (SPA) and Ramsar sites; • baseline conditions and assessment of the seascape character should be considered; • change in views from the Public Rights of Way (PRoW) should be considered; • details on the massing, location and orientation of the jetty should be provided in the ES; • in the cumulative assessment the long term nature of the jetty development should be considered; • views from the Quantock Hills Area of Outstanding Natural Beauty (AONB) should be included to assess the impacts on the Quantock Hills, in particular in the context of the lighting that is likely to have adverse impact on amenity; and • reference to the historic landscape character and the impacts on historic assets should be made in the ES. 21.1.8 The comments outlined above have been taken into account in the EIA and this ES. Consultation 21.1.9 Extensive consultation has been undertaken throughout the EIA process. 21.1.10 Consultation meetings were held and correspondence exchanged as part of Hinkley Point C Project consultation process with a variety of organisations, to discuss all stages of the LVIA, including details of the proposed jetty development itself. 21.1.11 The following organisations were consulted on landscape character designations and studies, relevant local policy, visual assessment methodology, viewpoint locations and mitigation proposals prior to the Hinkley Point C Stage 2 consultation: • Natural England; • Somerset County Council; • West Somerset Council; • Exmoor National Park; • Sedgemoor District Council; • Quantock Hills Area of Outstanding Natural Beauty (AONB) Service; • English Heritage; and • local residents and Stogursey Parish Council. 21.1.12 Comments from these consultees have been taken into account within this assessment. 21.1.13 Following the Hinkley Point C Stage 2 consultation a number of responses were received which were of relevance to the temporary jetty LVIA. These comments have been taken account of in this ES and the main resulting changes are as follows: Hinkley Point C Preliminary Works 21 - 2 Environmental Statement Temporary Jetty Development November 2010 • the methodology section was refined to provide clear explanation of the landscape and visual impact baseline evaluation and impact assessment; • the criteria for defining sensitivity of receptors and magnitude of impacts have been described in detail; • the landscape baseline evaluation was reviewed and extended to provide more detail on landscape character within the study area, in particular the local landscape character; • more information was provided in the visual baseline assessment to clarify how the sensitivity of individual viewpoints was established; • more information was provided in the landscape and visual impact assessment section in addition to the information provided in tabular form; and • the scale and presentation format of the panoramas recorded for the Principal and Secondary Viewpoints were revised. Assessment Content 21.1.14 A staged approach was used in the assessment, which is reflected in the structure of this Chapter. 21.1.15 The assessment of landscape and visual impacts arising from the jetty development has been undertaken for the landscape and visual study area and uses the LVIA methodology described in Section 21.3. 21.1.16 The baseline conditions described in Section 21.4 are based on landscape and visual desk studies and site visits carried out in relation to the jetty development. 21.1.17 Potential landscape and visual impacts resulting from the jetty development (including the design features but excluding further mitigation measures) are assessed in Section 21.5. Appropriate mitigation measures aimed at reducing the landscape and visual impact of the jetty development are identified in Section 21.6. The residual impacts following implementation of the mitigation measures are presented in Section 21.7. A summary of landscape and visual impacts is provided in Section 21.8 and the list of references used is provided in Section 21.9. 21.1.18 The cumulative landscape and visual effects are assessed in Chapter 25. For this assessment, the effects of the jetty development are assessed cumulatively with: • the site preparation works; • the Hinkley Point C Project; and • other relevant plans and projects. b) Objectives of Assessment 21.1.19 The LVIA described in this Chapter has the following objectives: • identify the landscape and visual receptors within the study area that may be affected by the jetty development; • describe and evaluate the baseline landscape and visual conditions within the study area, including landscape designations and relevant landscape planning policies, existing landscape and seascape character areas and visual receptors with the potential to be affected by the jetty development; • assess the landscape and visual impacts associated with the construction, operation, dismantling and restoration of the jetty development and, if required, its removal and site reinstatement (this assessment takes account of the main design Hinkley Point C Preliminary Works 21 - 3 Environmental Statement Temporary Jetty Development November 2010 features of the development but not the proposed planting or adoption of appropriate lighting controls, which are considered mitigation); • recommend mitigation measures, if required, to reduce the landscape and visual impacts of the jetty development (notably adoption of an appropriate lighting mitigation for the jetty development); and • assess the residual landscape and visual impacts of the jetty development. 21.2 Legislation, Policy and Guidance 21.2.1 The application site is located within the district of West Somerset (see Figure 21-1, Volume 3). Two other local planning authority areas, namely Sedgemoor and Taunton Deane, lie within the study area, which is described in detail in Section 21.3. No specific national or regional designations apply to the site. 21.2.2 This section considers the legislative and planning context of relevance to potential landscape and visual impacts associated with the jetty development in the study area. It includes guidance
