HUNTSPILL ENERGY PARK: ENVIRONMENTAL STATEMENT Landscape and Visual Impact Assessment 6 LANDSCAPE AND VISUAL IMPACT ASSESSMENT 6.1 INTRODUCTION (with reference to Appendix 6.1: Figures 6.1 and 6.2) 6.1.1 The Richards Partnership have been appointed to carry out a Landscape and Visual Impact Assessment (LVIA) of the development proposals for a hybrid planning application for an Energy Park, with all matters reserved apart from access. A full description of the development is provided in Chapter 5 of this ES. 6.1.2 Figure 6.1 shows the extent of the area subject to this application. The site (within the security fence) was the subject of a separate planning application in the autumn of 2011 for permission to remediate the site of hazardous materials and stabilise it in advance of any subsequent redevelopment, this application received planning permission in March 2012 and has since been implemented. 6.1.3 Given the long term objective for the site is for it to be developed as an Energy Park, it was agreed with both Sedgemoor District Council and Somerset County Council that for the purposes of the Landscape and Visual Impact Assessment chapter of the (EIA), the baseline situation will be as described in the Landscape and Visual Appraisal submitted in support of the earlier, 2011, remediation application. This has been agreed with both Sedgemoor District Council and Somerset County Council. This landscape and visual appraisal will be attached as an appendix to the EIA supporting the Main Application. 6.1.4 The landscape and visual impacts referred to later in the report are assessed separately in accordance with good practice1. They may be defined as follows: 6.1.5 Landscape character: impacts on the landscape or townscape may arise where the character of areas with a particular scenic quality or merit are modified by the development. 6.1.6 Landscape features: impacts on landscape features such as hedgerows, trees or landform may arise where features are lost or substantially modified as a result of the development. 6.1.7 Visual amenity: impacts on visual amenity may arise where features intrude into or obstruct the views of people, or where there is some other qualitative change to the view seen. 45 HUNTSPILL ENERGY PARK: ENVIRONMENTAL STATEMENT Landscape and Visual Impact Assessment 6.1.8 It should be stressed that ‘impacts’ can be changes for the better (resulting in positive effects) as well as changes for the worse ( resulting in adverse effects). 6.1.9 The landscape and visual appraisal was carried out through a desk study of relevant documents and by field study work undertaken from May 2011 to August 2012. The purpose of the site visits were to establish: The content and quality of the site’s existing landscape features. The character of the site and it immediate environs. The site’s visual relationship with its surroundings. The contribution of the site to the wider landscape. The people most likely to be affected by development on all or part of the site. 1 Best practice guidelines for landscape and visual assessment include: Landscape Character Assessment Guidance for England and Scotland (2002) the Countryside Agency Guidelines for Landscape and Visual Impact Assessment (2002) Landscape Institute and Institute of Environmental Management and Assessment. 6.2 LEGISLATION POLICY AND GUIDANCE (with reference Appendix 6.1: Figures 6.2 and 6.3) 6.2.1 The site lies within the administrative area of Sedgemoor District Council. At the time of writing the development plan consists of saved policies from the County Structure Plan and the Council’s Adopted Core Strategy with saved policies from the Sedgemoor District Local Plan 1991-2011. 6.2.2 On the basis that the former Royal Ordnance Factory (ROF) site does not contain any regional or county landscape designations, attention will focus on local policy contained within the Core Strategy and Local Plan. The corridor for the proposed road runs through the ‘Visually prominent areas of high quality landscape’ as identified in the Sedgemoor Landscape Assessment and Countryside Design Summary- 2003 (SLA) and will be considered in this context (See Figure 6.3). 6.2.3 The Sedgemoor District Local Plan does not accord any specific landscape designations to the site. However there are areas of the site designated as ‘Locally Important Nature Conservation Site’ and ‘Rail Facilities’. 46 HUNTSPILL ENERGY PARK: ENVIRONMENTAL STATEMENT Landscape and Visual Impact Assessment 6.2.4 As part of the evidence base of the LDF, Sedgemoor District Council have produced ‘Puriton Energy Park Supplementary Planning Document’ (SPD) which has now been adopted by the Council, and provides further information about the site’s delivery as an Energy Park allocated in the LDF . This document has been prepared to ‘guide and inform development of the brownfield site of the former Royal Ordnance Factory (ROF)’ and sets out clear principles to which any future development should adhere in order to: “Create a new environment that responds to the surrounding uses and strengthens links so that the development is seen as an integral part of the surrounding landscape well related to the nearby villages and respectful of the historic importance of the site..” (para 8.3) 6.2.5 The SPD is quoted in more detail later in this assessment in relation to the development proposals and their adherence to its principles. 6.2.6 The SLA is also adopted as supplementary planning guidance and identifies two areas of visual sensitivity; ‘Visually prominent areas of high quality landscape’ and ‘Areas of high sensitivity in relation to road corridors’ both of which will be considered later in this assessment. 6.2.7 The preferred route corridor for the overhead powerlines associated with the Hinkley Point C proposals runs to the east of the site, crossing it for a short stretch in the south eastern corner. This corridor is continuing to undergo consultation and it is not anticipated that these pylons and powerlines would be erected before 2018. Landscape and Visual Impact 6.2.8 The importance of the countryside and its role in providing a setting for towns and villages and to amenity purposes is recognised in Policy D14: Natural Environment of the adopted Core Strategy which states: “…proposals should ensure that they enhance the landscape quality wherever possible or that there is no significant adverse impact on local landscape character, scenic quality and distinctive landscape features as identified in the Sedgemoor Landscape Assessment and Countryside Design Summary. In particular: Siting and landscaping that take account of visibility from public accessible vantage points; 47 HUNTSPILL ENERGY PARK: ENVIRONMENTAL STATEMENT Landscape and Visual Impact Assessment The form, bulk and design of buildings having proper regard to their context in respect of both the immediate setting and the defining characteristics of the wider local area.” 6.2.9 The SLA identifies the former ROF site as being within the (c) ‘Levels’ sub category of “4. Levels and Moors”. The SLA identifies the nearby Polden Hills area, through which the proposed access road would pass, as being within the “Polden Hills” a sub-category of “6. Lowland Hills” (See Figure 6.6). The Polden Hills elevated nature results in the two landscape character areas being inextricably linked in both landscape and visual terms. In view of this any development proposals need to be mindful of the different landscape types characteristics and their sensitivities. 6.2.10 Under a section entitled “Sensitivity to visual impact and the capacity for new development/key principles for new development” (Pg 47, para 4.63) the SLA states: “The opportunity for screening of new low level development as viewed from other areas at low elevation means that capacity for development in the Levels is often higher than in many other areas of the District. This is, however, dependent on the extent of existing tree cover or potential for this to be reinforced by new planting. Sites which lie close to the higher ground and view corridors such as the ridge of the Polden Hills will also need to take account of views from these vantage points.” 6.2.11 Given The Site’s relationship with the adjacent Polden Hills these points are particularly relevant to any development strategy for the site. 6.2.12 The Puriton Energy park SPD also recognises the importance of the potential landscape and visual impact on the wider area, stating in para 8.8.2 “It will be important that measures to reduce the visual impact of the development on the landscape character are fully considered as part of the redevelopment proposal…. Though the mature and established landscaping around the site does currently provide effective screening for the lower buildings this is more challenging for the taller elements.” 6.2.13 In a similar vein to landscape and visual impact Policy D17 – Historic Environment of the Core Strategy states: “All development should contribute to enhancing and maintaining the historic environment, ensuring a continued role in distinguishing the District’s unique sense of identity and place.” 48 HUNTSPILL ENERGY PARK: ENVIRONMENTAL STATEMENT Landscape and Visual Impact Assessment 6.2.14 As noted earlier, the 1940’s development of the former ordnance factory effectively removed agricultural practices and superimposed industrial activities across most of the site. Whilst the development of the site fundamentally changed its landscape character, a significant number of the historic fabric of drainage ditches and field edges are still evident, particularly in the north eastern area of the site. 6.2.15 Policy D20 – Green Infrastructure of the Core Strategy states that: “Green Infrastructure (GI) will be safeguarded, maintained, enhanced and added to, as appropriate, to form a multi-functional resource which meets the following objectives: Provide an accessible network of green spaces which meet recreational needs, cultural needs including education and interpretation, are safe and secure, and support physical health and mental wellbeing.
