Introduction The Councils (Wiltshire Council and Swindon Borough Council) consulted on an initial list of site options for soft sand and sand and gravel extraction in Wiltshire and Swindon from August to October 2010. The consultation document highlighted potential issues that might be associated with development of the sites and invited comments from various consultees including local communities. A number of consultees questioned the impacts that the site options might have on the landscape character of the surrounding area and the level of visual impact that may be apparent. Following consultation 40 site options were regarded as unlikely to be deliverable given the constraints to development and have consequently been dropped from further consideration. The 22 remaining site options have now been subject to further evidence gathering and assessment to ensure that any decision on their suitability is based on robust evidence and qualified professional judgement. As would be expected all of the remaining site options are in rural areas. The following pages provide context for each of the site options highlighting the issues that were raised during the consultation. Wiltshire Council’s Landscape Officer has reviewed the available information and provided landscape character, and visual, assessment, for each of the site options and a professional view on the potential for each of the sites to accommodate mineral working. A detailed assessment of landscape character, site photographs, field surveys and annotated field survey maps can be viewed as appendices to the back of this report. 1 2. Summary of Findings Wiltshire Council’s Landscape officer reviewed the available data in light of the comments submitted during consultation in 2010 and the results of detailed landscape assessments carried out at each site. A conclusion as to the suitability of each site from landscape and visual impact grounds is summarised in the table below. Area Site Ref Site suitability to accommodate quarry activity Upper Thames Valley U2 Difficult Upper Thames Valley U3 Yes (with appropriate mitigation) Upper Thames Valley U4 Difficult Upper Thames Valley U5 Yes (with appropriate mitigation) Upper Thames Valley U6 Yes (with appropriate mitigation) Upper Thames Valley U7 Yes (with appropriate mitigation) Upper Thames Valley U9 Yes (with appropriate mitigation and no adverse impact on North Meadow) Upper Thames Valley U16 Yes (some sections unsuitable – Chancel and woodland) Upper Thames Valley U17 Yes (with appropriate mitigation) Upper Thames Valley U18 Yes (with appropriate mitigation) Upper Thames Valley U22 Yes (if appropriate restoration masterplan is developed) Upper Thames Valley U23 Yes (with appropriate mitigation and subject to archaeological constraints) Calne Area C3 Yes (with appropriate mitigation) Calne Area C15 No to North, Yes to rest of site Calne Area C16 Yes (but only with advanced planting to east) Calne Area C18 Difficult South East of Salisbury SE1 No South East of Salisbury SE2 Yes (with appropriate mitigation) South East of Salisbury SE3 Yes (with appropriate mitigation) Salisbury Avon SA1 No Salisbury Avon SA2 No Bristol Avon BA4 Yes (with appropriate mitigation) The following sections of this document provide the details of finds and features recorded through desktop and on-site assessment and the view of the Wiltshire Landscape officer on the potential for each site option to accommodate minerals activity on landscape and visual impact grounds. 2 3. Assessment Methodology Following the consultation exercise held in 2010, the remaining potential site options included within this report were identified as requiring detailed assessment to determine the potential for landscape and visual impact. The assessments undertaken for these remaining potential site options broadly followed a 3 stage process:- Stage 1 – Desk Study A review of the available mapped and photographic information, county and national landscape planning policy together with gathering relevant information on landscape designations and landscape character assessment was undertaken. Comments received through the initial consultation exercise held in 2010 were also used to detail potential local landscape and visual impacts/issues. From this a check list of potential issues and concerns was generated to broadly inform and guide the site assessment stage for each site. Stage 2 – Site Survey Each site was visited by Wiltshire Council Landscape officers during May 2011 and potential impacts/opportunities were noted through an assessment field survey sheet. The site survey would provide local data to support the desk study baseline landscape and character description, review potential landscape impacts, identify key visual receptors and consider mitigation options. In addition a photographic record was taken for reference purposes. The photographic record comprised a series of digital photographs taken with a Digital SLR camera to represent the typical human perspective. These images were used to illustrate the existing character and condition of the sites, as well as identify potential visual receptors and give an indication of the degree of exposure they would have to views of potential mineral activity. A field map was also created to record potential sight lines, visual impacts, receptors, landscape detractors, vegetation (such as hedgerows and trees) and the position where photographs were taken. Stage 3 – Reporting A summary of the comments raised through consultation, site profile, notable landscape and visual features, landscape quality and capacity to accommodate change for each potential site option is provided at the front of this document. The full findings for each site assessment are provided as appendices to this document and cover: · Assessment of landscape character · Record of potential landscape impacts · Record of potential key visual receptors · Record of potential visual impacts · Site field maps · Site photographs 3 4. Landscape and visual impact of the site options within the Upper Thames Valley Mineral Resource Zone Site Option U2 Size (ha): 10.2 Context Northings: 200100 The site option is located adjacent to the Wiltshire / Eastings: 413100 Gloucestershire boundary and is in agricultural use. The Resource type: surrounding area is also predominantly agricultural in use. sharp sand and gravel The nearest settlement is Meysey Hampton to the west. Current use: agricultural There are also dwellings adjacent to western and southern boundaries of the potential site and in close proximity at Marston Hill. Estimated resource yield: 355,250 tonnes The nearest main road is the A417 approximately 150m to north, although the existing access road linking the site with the A417 is weight restricted to 7.5 tonnes. The land adjacent to U2, in Gloucestershire is allocated as a Preferred Area for sand and gravel extraction in the Gloucestershire Minerals Local Plan. Summary of key issues raised during consultation An assessment of the impact to loss of agricultural land should be undertaken. This will further erode the agricultural use of land in the area. The precise boundary of any allocation must be drawn to reflect an appropriate separation distance from residential properties. Extraction would cause significant loss of quality of life to residents living in Marston Hill and Meysey Hampton. Summary of notable landscape/visual features in the area Strong/intact hedgerows with some hedgerow trees. Properties scattered along positions to the west and south west boundary of the site. Also properties evident to the east of the site (in the distance). Landscape quality/condition Good Capacity to accommodate Difficult (working of the site would require mitigation in landscape change (Landscape the form of bunds that may alter the landscape Officer view) character of the area). 4 Visual Receptor Sensitivity of Potential Residual Potential Visual Mitigation (Type of receptor) Receptor Impact on Receptor Measures (Low/Medium/ (Negligible/Slight High) Adverse/Adverse) Properties to west, High Adverse Due to proximity of south west and properties (adjoining the east site), appropriate mitigation for visual impact would be difficult. Putting bunds in place would lead to a loss of amenity and would cause harm to the landscape character. Potential for landscape blight for those living adjoining to the site. 5 Site Option U3 Size (ha): 106.1 Context Northings: 197000 The site option is situated adjacent to the active military Eastings: 413500 airbase at RAF Fairford and is
