Abstract:		 A programme of environmental archaeological assessment was carried out at the site in order to (1) to clarify the nature of the sub-surface stratigraphy; (2) to clarify the nature, depth, extent and date of any Alluvium and organic/Peat deposits; (3) to investigate whether the sequences have the potential to contain any artefact or ecofact evidence for prehistoric or historic human activity. Deposit modelling revealed that the sequence at the site consists of bedrock Chalk, overlain by Late Devensian gravel, Holocene alluvium and modern Made Ground. The gravel surface at the present site falls towards the north to between -1.06 and -1.25m OD, perhaps indicative of a palaeochannel that might be aligned broadly east-west and whose main axis lies to the north of the site. Towards the south and east of the site the gravel surface rises to between 0.23 and 1.4m OD, perhaps indicative of a gravel 'island' that might have been elevated above the level of the surrounding floodplain during the prehistoric period. The alluvium overlying the gravel is typical of deposition in a low-energy fluvial environment, perhaps with episodes of reduced flow and short-lived transitions towards semi-terrestrial conditions, perhaps on the margins of a stream or pond. Radiocarbon dating of the base of the organic-rich unit recorded between 0.18 and -0.20m OD suggests that accumulation began sometime around ca. 720 to 895 cal AD (1185 to 1055 cal BP; Anglo-Saxon). The results of the assessment are indicative of an open and anthropogenically modified environment during the accumulation of this organic-rich horizon, and are strongly indicative of very nearby cultivation and/or crop-processing. The presence of aquatic taxa is indicative of nearby slow-flowing or standing water, perhaps on the margins of a stream or pond. No further analysis was recommended.
