Evaluation by J Stevenson of ASE prior to the submission of a planning application for residential development. Evidence for Iron Age utilisation of the landscape was revealed, including some limited settlement evidence in the form of a ring gully, although it seemed that the main focus of occupation was likely to be off-site. One area contained an extensive series of pits, postholes and ditches of Late Iron Age to Early Roman and 3rd–4th century dates. A buried former water channel was also recorded, as was evidence for 13th century activity on the site.

Phase I of a large-scale evaluation by A Ford of OA prior to the submission of a planning application for residential development. A small number of worked flints were recovered, suggestive of low-level early prehistoric activity in the general vicinity. Of more significance was evidence of a Late Iron Age to 1st century Roman settlement, with indications that an intensification of activity might have occurred towards the end of this period.

Metal detector survey under the direction of D Williams of SCC recovered only three objects pre-dating the 17th century. These were a buckle plate of medieval or Tudor date, a brooch dating to the 1st century AD, and an Early Iron Age, c 600–450BC, bow brooch.

Watching brief carried out by J Perry of SutAS during the construction of a mobile telephone network mast. Numerous fragments of worked and burnt flint were recovered, together with a fragment of burnt flint-tempered pottery of probable Late Bronze Age to Early Iron Age date, from sandy deposits interpreted as being riverine in origin. The report concludes that there was no evidence for archaeology in the trench.

Evaluation and watching brief by J Pine of TVAS on further areas of the proposed University of Surrey expansion site, following the previous evaluation and excavation works in 2002 and 2003. The evaluation produced evidence for Early to Middle Bronze Age activity, in the form of isolated pits. Medieval activity was also noted, in the form of pits, ditches and a possible hearth. Given their proximity to the nearby moated site of Manor Farm, it is assumed that they are associated with activity relating to this site, although the dating evidence was not clear.

Continuing excavation by G Hayman of SCAU south of those areas excavated in previous years revealed further features of Bronze Age, Iron Age and Roman date. The Bronze Age features consisted mostly of ditches belonging to a co-axial field system that developed during the Late Bronze Age, but also included one large pit and a small pit or posthole. The field system has been traced across all areas of the quarry that have been examined since work began in 1999 and extends for an unknown distance beyond it.

Geophysical survey by A Bartlett of BCC, with a supplementary evaluation by P Jones of SCAU, in order to test the potential effectiveness of geophysical survey over the site. A number of magnetic anomalies were detected, although no corresponding archaeological features were revealed, suggesting that full geophysical survey of the site would not be productive. Subsequent evaluation involving the excavation of 464 trenches by A Taylor of TVAS in advance of possible mineral extraction revealed a wide range of finds and deposits.

Evaluation by E Eastbury of MoLAS prior to redevelopment found that most of the site had suffered severe truncation of any potential deposits during the construction of the existing buildings. A small area was found to contain a deep feature, containing stratified material dating from the Late Neolithic to Roman periods. Owing to the large size of the feature, its extent or exact nature could not be verified. A subsequent watching brief on the area where the feature was presumed to continue provided no further information.

Evaluation by J Stevenson of ASE in advance of residential redevelopment involved the excavation of eight trenches. One revealed an undated tree bole; a second, two pits/postholes and a gully all of probable prehistoric date, and a grave of probable Anglo-Saxon date excavated in the 19th or early 20th century; a third, four small pits, three of prehistoric date, and one of Early/mid-Iron Age date, and two very large pits of later Iron Age date thought to be used for grain storage.

Metal detector survey under the direction of D Williams of SCC and A and D Graham of SyAS recovered metal objects of Roman, medieval and later date, and a single pottery sherd of possible Iron Age date. The survey shed no light on the interpretation of a circular enclosure identified on aerial photographs of the site. (Bulletin 369)
