The survival and extent of thearchaeological deposits is often uncertain and consequently, the magnitude ofchange is difficult to predict with any certainty.Table 4.2: Factors for Assessing the Magnitude of ImpactMagnitude of ImpactMajorModerateMinorNegligibleNo ChangeExampleChange to most or all key archaeological materials, such that the resource ittotally alteredComprehensive changes to settingChanges to many key archaeological materials, such that the resource isclearly modifiedConsiderable changes to setting that affect the character of the assetChanges to key archaeological materials, such that the asset is slightlyalteredSlight change to settingVery minor changes to archaeological materials, or settingNo changeAssessing Magnitude of ImpactsAn impact is defined as a change resulting from the scheme that affects the culturalheritage resource. Impacts, both positive and negative, which may occur during thelife cycle of road scheme projects, are detailed below.Significance of EffectThe significance of effects for the archaeological resource is derived by combiningthe value of the resource with the magnitude of the impact for each cultural heritageasset. The following table illustrates how information on the value of the asset andthe magnitude of the impact are combined to arrive at an assessment of thesignificance of effect. The matrix is not intended to ‘mechanise’ judgement of thesignificance but act as a check to ensure that judgements regarding value,magnitude of impact and significance of effect are reasonable and balanced.28

The landscape surrounding Elkesley is one ofpredominantly agricultural land. There are a number of low hills surrounding thevillage, which rise to a maximum height of 55 m OD. Four rivers (the Poulter, the Idle,the Maun and the Meden) converge close to the route of the A1(T) resulting inshallow river valleys in the area. The geology of the area is fine-medium roundedsand overlying mudstone and limestone. The topography and geology of the area arein line with preferred areas of settlement in prehistoric and historic times.Within the study area there are a total of 38 cultural heritage assets, which consist ofarchaeological sites, artefacts and historic buildings. A full list of these assets can befound in the attached annex. There are no scheduled monuments, registered parksand gardens or registered battlefields within the study area. There are seven listedbuildings and seven buildings considered to be of local historical and architecturalimportance within the study area. None of these heritage assets will be directlyimpacted by the proposed scheme.According to the Historic Landscape Characterisation undertaken by NottinghamshireCounty Council, the study area lies within a landscape characterised by regulargeometric fields, irregular fields, modern fields, modified modern fields and semiirregularfields. These enclosure types all date from the 19th century at the latest andare therefore capable of incorporating further change.The most relevant archaeological features that may affect the Preferred Version area collection of linear crop marks which appear to the west and northwest of thescheme (Site 1a). These have been recorded and transcribed from aerialphotographs by the Royal Commission on the Historical Monuments of England(RCHME). From the transcribed plans parts of these features appear to intersect withthe proposed layout of the junction improvements where the improvements runparallel to the current A1(T). It is also likely that these features extend further to theeast than is recorded by the RCHME. These crop marks suggest that an extensiveRomano-British settlement was located here in the prehistoric period. Althoughpedological and geological conditions, together with land use and agriculturalpractices can affect the identification of crop marks, given their quantity, morphologyand distribution they can be reliably classified as archaeological in nature.29
