Excavation by SHAHT, under the direction of G Cole, revealed evidence of prehistoric, medieval and later activity. Two phases of prehistoric activity were recorded. The first comprised the terminal ends of two ditches, one truncating the other, together with the lower levels of a rampart and a series of post-bases; and the second comprised flint foundations and associated stake holes. Fragmentary remains of two hearth bases were noted, and a well from which medieval pottery and hearth fragments were recovered was partially excavated.

Evaluation by G Hayman of SCAU, for Taylor Woodrow Property, in advance of the redevelopment. At the rear of the site, two intercutting ditches of possibly Roman date were revealed; at the front of the site, one medieval and one undated ditch were revealed. A few sherds of prehistoric pottery were also recovered.

Excavation by G Hayman of SCAU, for Tasman House Developments Ltd, in advance of redevelopment of a site that was partially evaluated in 1994.

Excavation and a subsequent limited watching brief by M Dover of SCAU, and geoarchaeological and palynological investigations by ArchaeoScape Consulting, for the Clerical and Medical Investment Group, in advance of office redevelopment. The earliest evidence recovered from the site was a collection of prehistoric flints. The earliest features identified were two human burials, one a double inhumation - possibly a parent and child. These burials are probably outliers from a more formal cemetery, outside the Roman town, that has not as yet been located.

Excavation by J McKinley of Wessex, for MEPC UK Ltd, in advance of redevelopment. The largest feature revealed was a substantial channel at the northern end of the area, presumably originally water-filled, that went out of use before the Roman period and was then infilled with rubbish. A fragment of prehistoric pottery recovered adjacent to this channel hints at earlier occupation on, or in the vicinity of the site. A variety of features of mostly Roman date, but some likely to be medieval, were recorded on the site.

Evaluation by SutAS, for the British Marine Industries Federation, of land proposed for office development revealed alluvial silts and peats, which were sampled for palaeo-environmental analysis. Analysis by ArchaeoScope Consulting indicates that sedimentation commenced prior to 7000 BC (early Holocene/Mesolithic). The deposits represent the fill of abandoned river channels, probably being actively created and infilled during a period of at least a thousand years in the early Holocene.

Evaluation by T Howe of AOC, for Anglerare Ltd, in advance of redevelopment of land to the rear of these properties, revealed little evidence for medieval activity. Sealed below a layer of redeposited brickearth, however, a few features of prehistoric date were found. Two of these contained fragments of Late Bronze Age or Early Iron Age pottery, as well as some burnt flint, another simply burnt flint. Residual flints of Mesolithic or Neolithic date were also recovered from one of these features.

Evaluation by J Robertson of SCAU, for Green Property (UK) Ltd, in advance of redevelopment for offices, revealed no features of archaeological interest. A number of finds were recovered however. These included pieces of struck prehistoric flint and numerous sherds of pottery, ranging in date from the 12th century onwards, as well as fragments of tile, clay pipe and animal bone. It is likely that this area was formerly in agricultural use and that most of these finds are the result of manuring.

Evaluation of the archaeological and historic landscape by C Currie of CKC Archaeology, in conjunction with SyAS, for SCC, with reference to them being proposed as Areas of Historic Landscape Value. The survey recorded a series of features, including a number of potential barrow sites (there is at least one authenticated prehistoric barrow on Cockcrow Hill), at least five historic ponds, and a large area of linear earthworks, possibly the remains of quarrying.
