Environmental Statement Volume 2: Part 1 Landscape and Visual Impact Assessment March 2014 Volume 2 of the Environment Statement has been prepared by Gillespies LLP, Montague Evans LLP and DesignHive. It is formed of four parts: Part One: Landscape and Visual Impact Assessment (LVIA) (This document) (Gillespies LLP) Part Two: Assessment of the Impact on Heritage Assets (AIHA) (Gillespies LLP and Montague Evans LLP) Part Three: Figures to Support Landscape and Visual Impact Assessment & Assessment of the Impact on Heritage Assets (Gillespies LLP) Part Four: Verified Photomontages: Methodology and Supporting Evidence (DesignHive and Gillespies) CONTENTS 1 Introduction 5 2 Legislation, Policy And Guidance 8 3 Landscape Baseline 13 4 Visual Baseline 30 5 Assessment of Landscape Effects 42 6 Assessment of Visual Effects 56 7 Compliance with Landscape Planning Polices and Strategies 77 8 Summary and Conclusions 81 GLOSSARY AND ABBREVIATIONS REFERENCES APPENDICES LVIA Appendix 1: LVIA Methodology LVIA Appendix 2: National Character Area: 132 Salisbury Plain and West Wiltshire Downs LVIA Appendix 3: County Landscape Character Type: Chalk River Valley LVIA Appendix 4: District Landscape Character Area: A4 Lower Avon Narrow Chalk River Valley LCA LVIA Appendix 5: Constable and Salisbury: Harnham Water Meadows Trail LVIA Appendix 6 Minutes of the Meeting of Strategic Planning Committee, Wednesday, 28th September, 2011 with regard to Planning Application S/2011/0207/FUL Landscape and Visual Impact Assessment 5 Salisbury Gateway, Southampton Road ES Volume 2 Part 1 1 Introduction 1.1 The development 1.1.1 In March 2011, Gillespies was instructed by Salisbury Site LLP to prepare a Landscape and Visual Impact Assessment (LVIA) of the Salisbury Gateway Development as part of an Environmental Impact Assessment (EIA) being undertaken for the development. Gillespies was also instructed to prepare landscape and public realm proposals for the development. A planning application (ref S/2012/0873) was submitted in March 2012 which has now been withdrawn. 1.1.2 Salisbury Site LLP decided to revise the proposals for the Salisbury Gateway Development and in 2013 Gillespies was asked to revise the landscape and public realm proposals and to prepare a LVIA to accompany the revised application. This LVIA forms part of the Environmental Statement but is submitted as a separate document and forms Part One of Volume 2 of the ES. The Figures to accompany this assessment form Part Three of Volume 2 and the Verified Photomontages prepared for a selection of the viewpoints form Part Four of Volume 2. 1.1.3 The proposed development is described in the Design and Access Statement and in Chapter 4 of the ES. The development consists of a Sainsbury’s superstore (the store) and Petrol Filling Station (PFS) and Kiosk located on Southampton Road. The store, a bespoke design by LSH Architects, with weathered timber and glazed elevations and a gently curving roof, has been developed specifically for this site. The Southampton Road frontage consists of a wide band of landscaping with some parking located between the landscaped frontage and the store. The remaining parking is located beneath the store. The service yard is to the rear of the store. The Landscape proposals are described in the Landscape Proposals Design Report which includes the Landscape Masterplan (Drwg. OX4600-10_LM01 Rev T) which forms one of the application drawings. 1.1.4 The application site is 9.67 ha although this includes highways land. The built form is confined to the northern and eastern parts of the application site (the site) and within the LVIA this part of the site is described as the development area. The site and the development area are shown on Figure SR PL001 Site Location Plan. 1.1.5 The southern half of the site (4.37 ha) between the developed area and the River Avon incorporates sustainable urban drainage and flood attenuation measures, but is free from built form and is described in the application as the sustainable wetland. The sustainable Landscape and Visual Impact Assessment 6 Salisbury Gateway, Southampton Road ES Volume 2 Part 1 wetland forms part of the River Avon Valley floor and the application includes a timber boardwalk and viewing platform adjacent to the river with managed public access. From the boardwalk and viewing platform there are views along the River Avon Valley towards Salisbury Cathedral to the west and towards Britford Church to the east. 1.1.6 The application also incorporates a flood prevention barrier along the western edge of the Wessex Water treatment plant. 1.1.7 Changes since the previous application include: A reduction in the height to the store; A reduction in the footprint of the store; A slight change in the location of the store to increase the distance from the eastern boundary; Removal of glazing from the southern elevation of the store; A revised design for the sustainable wetland, inspired by the historic character of the site, that visually echoes the character of the surrounding water meadows; Prioritising of ecological enhancements; Mounding with planting introduced on the Southampton Road frontage of the PFS; Revised highways proposals; Addition of a flood prevention barrier along the western edge of the Wessex Water treatment plant; and The combined heat and power plant has been omitted. 1.1.8 A comparison of architectural proposals between Application ref S/2012/0873 and the current proposals can be found in section 4 of the Design and Access statement. 1.2 Landscape and Visual Impact Assessment Methodology 1.2.1 Since the first application there has been a revision of the Guidelines for Landscape and Visual Assessment (GLVIA3) (Ref.i) published by the Landscape Institute (LI) and Institute of Environmental Management Assessment (IEMA). Consequently it was decided that the current LVIA should be prepared in accordance with the advice set out in GLVIA 3. 1.2.2 The methodology used by Gillespies is also based on principles regarding landscape character assessment set out in guidance from the Countryside Agency (now Natural Landscape and Visual Impact Assessment 7 Salisbury Gateway, Southampton Road ES Volume 2 Part 1 England) and Scottish Natural Heritage on Landscape Character Assessment: Guidance for England and Scotland (Ref ii). 1.2.3 The methodology used in this LVIA is set out in LVIA Appendix 1. 1.3 Scoping, agreed viewpoints and photomontages 1.3.1 The scope for the LVIA had been agreed with Wiltshire Council for the application ref S/2012/0873. Following that submission Wiltshire Council raised the issue of potential impacts on heritage assets including the Setting of Salisbury and Wilton. These issues have been addressed in a separate assessment, The Assessment of Impacts on Heritage Assets which forms Part Two of this Volume 2 of the ES. 1.3.2 Subsequent to the submission of application ref S/2012/0873 it was agreed with Wiltshire Council that a number of verified views would be produced. The verified views were produced in order to illustrate both the landscape and visual assessment and the assessment of impacts on heritage assets. Some locations were at existing viewpoints assessed in the LVIA, but there were also a number of additional viewpoints. 1.3.3 A scoping report with regard to the current LVIA was sent to the Wiltshire Council in December 2013 (as part of a wider scoping report for the whole ES) and a response received from Wilshire Council in February 2014. Issues raised in the response to the Scoping Report are covered either in this LVIA or in The Assessment of Impacts on Heritage Assets. Landscape and Visual Impact Assessment 8 Salisbury Gateway, Southampton Road ES Volume 2 Part 1 2 Legislation, Policy And Guidance 2.1 Introduction 2.1.1 This section identifies and describes legislation, policy and guidance of relevance to the assessment of potential landscape and visual effects associated with the construction and operation of the proposed development. 2.2 International 2.2.1 The European Landscape Convention (ELC), which was signed by the UK in February 2006 and became binding in 2007, is the first international convention to focus specifically on landscape issues and aims to protect, manage and plan landscapes in Europe. 2.2.2 The ELC defines landscape as: ‘An area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors.’ 2.3 National Legislation, Planning Policy and Guidance 2.3.1 National Planning Policy is set out in National Planning Policy Framework (NPPF), March 2012 (Ref iii). Paragraph 17 of the NPPF includes 12 principles of plan making and decision-taking. These include the principles that planning should: • ‘take account of the different roles and character of different areas, …. recognising the intrinsic character and beauty of the countryside and supporting thriving rural communities within it.’ • ‘contribute to conserving and enhancing the natural environment and reduce pollution. Allocations of land for development should prefer land of lesser environmental value, where consistent with other policies in this Framework.’ 2.3.2 Section 7 of the NPPF outlines the Government’s policy regarding design. It emphasises that good design is a key aspect of sustainable development, is indivisible from good planning, and should contribute positively to making places better for people. Paragraph 58 states planning policies and decisions should aim to ensure that developments: will function well and add to the overall quality
