In addition the site has been comprehensively evaluated by geophysical survey and trial trenching. The results from the extensive investigations on the existing Whitemoor Haye Quarry have also been reviewed. The data gathered has provided the information required with which to appropriately assess the impact of the development proposals on the archaeological and historic landscape. The assessment of direct impacts on archaeology and cultural heritage assets within the proposed development boundary shows that significant impacts in EIA terms comprise a high magnitude of change to the small amount of identified Prehistoric archaeological evidence in trial trench 11 (quarry phase 2), being a low sensitivity receptor, and the uninvestigated, but believed Prehistoric archaeological evidence as detailed by cropmark evidence in Field 1 (quarry phase 5), also a low sensitivity receptor. Whilst the predicted impact to both these areas is of moderate significance, it can be appropriately mitigated by the implementation of an approved scheme of archaeological works prior to development. This will preserve the archaeological interest of these parts of the site ‘by record’. There are no other identified significant direct effects on the archaeological and heritage resource as a result of the proposed quarry extension. There will be an impact to other (later) archaeology identified within the confines of the Site and potentially to other undated and unidentified archaeological remains. However, the assessed sensitivity of these receptors (being low), together with the proposed mitigation, has identified all impacts as being of minor magnitude which does not equate to a significant impact in EIA terms. The assessment of indirect impacts on all cultural heritage assets within the study area shows that significant impacts in EIA terms comprise a ‘medium’ magnitude of change to the Grade II Listed Roddige Farmhouse, being a Medium sensitivity receptor. Whilst the predicted impact is of moderate significance, in that the 4 | P a g e Alrewas South, Staffordshire secondary setting of the farmhouse extends to the site, there are no clear functional or significant historic associations with this wider landscape. The wider rural landscape beyond the farmhouse’s associated gardens and former yards comprise a ‘backdrop’ rather than an integral part of the setting of the building. The creation of soil storage bunds, which will be grassed over and placed along the northern, eastern and western edges, will afford an increased protection to the secondary setting of the building whilst quarry operations take place. Quarry operations within the vicinity of Roddige Farmhouse will be temporary in nature, lasting c. 5 years prior to approved restoration taking place. Following site restoration the secondary setting of the building will be appropriately restored. There are no other identified significant indirect effects on the archaeological and heritage resource as a result of the proposed quarry extension. The extension is not located within the primary setting of any surrounding cultural heritage asset. There will be changes to long distance and obscured views in some circumstances, but none of these changes are relevant to planned views or vistas from cultural heritage assets and those changes are not assessed as compromising the understanding or historic importance of any feature. 5 | P a g e Alrewas South, Staffordshire CULTURAL HERITAGE 1 Introduction 1.1 Phoenix Consulting Archaeology Ltd has been instructed by Lafarge Tarmac to prepare a Cultural Heritage assessment for their proposed Alrewas South Quarry Extension near Alrewas, Staffordshire. This document assesses the extent and importance of known archaeology and other features of cultural heritage interest in and around the proposed extension (‘the Site’). It also discusses the likelihood of further archaeological finds being made on site, the potential impacts of the proposed development on archaeology and other features of cultural heritage interest, and a range of mitigation measures to minimise those potential impacts. 1.2 Specifically, the document evaluates direct and indirect impacts on archaeological finds and sites in addition to any potential indirect impacts on other cultural heritage components in the surrounding landscape (including Listed Buildings and Conservation Areas). 1.3 Historic Battlefields, Registered Parks and Gardens and World Heritage Sites are not considered within this assessment because there are no such designations within the study area. 1.4 National and local policy guidelines on archaeology recommend that important archaeological sites should be protected and where possible preserved in situ. However, for features of lesser importance preservation by record is an acceptable alternative. If important sites are assumed to exist, a condition may be attached to any granted planning permission which requires their preservation in situ or outlines a scheme of further archaeological investigation. 6 | P a g e Alrewas South, Staffordshire 2 Assessment Methodology Objectives 2.1 The key objectives of the impact assessment are to: ● identify key archaeological finds and sites, including Scheduled Monuments, on and within 2km of the Site; ● identify key Listed Buildings and Conservation Areas within 2km of the Site; ● identify any Registered Parks & Gardens within 2km of the Site; ● assess the impacts of constructing, operating and decommissioning the quarry upon the cultural heritage assets listed above, including consideration of their setting; ● identify measures for avoiding or mitigating potential impacts; ● detail any residual impacts that cannot be mitigated. Key Tasks 2.2 The assessment has involved the following key tasks: ● a desk-based assessment to collect all readily available information on the archaeology and historic aspects of the landscape and to assess the probability of the survival of archaeological remains – see Annex 1a; ● assessment of the results of the geophysical survey to obtain information concerning the presence, character, date and level of preservation of any surviving archaeological remains across the site – see Annex 1b; ● targeted trial trenching to assess presence and extent of archaeology on the site, its date and level of preservation – see Annex 1c; ● assessment of the results of the archaeological investigations across the National Memorial Arboretum ‘overflow’ car park, which covers a part of the application area – see Annex 1d; ● consultation with relevant parties; 7 | P a g e Alrewas South, Staffordshire ● site visit to assess setting of cultural heritage assets; and ● consideration of a range of measures to mitigate potential impacts of the proposed development on known and potential archaeology and other cultural heritage assets. Desk-Based Assessment 2.3 To assess the probability of the survival of archaeological and other cultural heritage assets across the Site a desk-based assessment was undertaken (Annex 1a). This collected all available data of the study area and its surrounds (Coates & Richmond 2009). The information was considered in the context of 'background information' on the physical environment, particularly geological and geomorphological conditions and past and present land-uses of the area. The sources of information used in the desk assessment are summarised below: Historic Environment Record 2.4 The Historic Environment Record (HER) of Staffordshire County Council was made available during the assessment. The Council HER Officers assisted with the collection of known records for the area. Computer printouts of relevant archaeological information were obtained from these sources. 2.5 The HER is not a complete listing of the actual archaeology and other cultural heritage features which may exist across, or in the vicinity of the site, nor is it seen as such by the Council Archaeological
