Evaluation by G Hayman of SCAU, for Airways Housing Society Ltd, in advance of residential development in the grounds of this 17th century building. A number of ditches were identified, of both Roman and early medieval (11th-12th century) date. The recovery of a number of pieces of struck and burnt flint also suggests prehistoric activity. A subsequent watching brief on construction revealed little more. (314, 321)

Evaluation involving a geophysical survey and trial trenching was carried out on this prospective mineral site, by the Bartlett-Clark Consultancy and G Hayman of SCAU respectively, for Henry Streeter (Sand & Ballast). This work revealed a scatter of prehistoric features across the site and a concentration of features of Roman date indicating settlement, probably a small farmstead, at the southern end of the site.

Evaluation by M Dover of SCAU, for Berkley Hambro & Conlyon Investments, in advance of redevelopment of this site. Some areas were found to have been previously disturbed, but a spread of gravel containing sherds of Roman pottery and tile was tentatively identified as a track surface of that date. (314)

Excavation by J Robertson of SCAU for the Metropolitan Police Service followed on from evaluation in 1995; the site for the new police station lies on the fringes of the Roman and later settlement of Staines. The excavation revealed a number of ditches that had been cut parallel to the roadline.

Evaluation by G Hayman of SCAU, for Greenham Construction Materials Ltd, of an area proposed for mineral extraction (and a flood relief channel) identified a silty deposit containing worked flint, sherds of prehistoric (probably Bronze Age) pottery and a couple of sherds of Roman pottery, which overlay a buried river channel.

Evaluation and subsequent excavation was carried out by J Robertson of SCAU for Nicholas King Homes, before residential development of the school grounds. The site lies outside the Roman and medieval settlement of Staines but in close proximity to the parish church. Numerous features of late Saxon date were revealed, confirming that there had been some shift of settlement during that period away from the site of the Roman town. Some features of Saxo-Norman date were identified, but insufficient to establish whether Duncroft was the site of Staines’ Manor House.

Evaluation by R Poulton of SCAU, on behalf of United House Construction, was carried out in advance of redevelopment. Two phases of flood deposits (Roman and post-Roman) were revealed below modern disturbance. These in turn overlay natural brickearth and gravels. The evaluation found no evidence for Roman or earlier features sealed by the flood deposits; in particular no trace of the possible Roman ditch identified by the Spelthorne Archaeological Field Group, during their work in 1992, was revealed in either trial trench.

Evaluation and subsequent excavation by J McKinley of Wessex, for MEPC, was carried out in advance of the redevelopment of the estate. The evaluation identified three broad zones within the site: the edge of the town gravel island, a broad alluvium filled channel to the north and, beyond this, a second gravel island. Subsequent work concentrated on the two islands. Excavation on the northern island (centred at TQ 033 719) recorded part of an enclosure/field system of Bronze Age date and another of Roman date, as well as agricultural features from the medieval period.

Evaluation by J McKinley of Wessex, for MEPC, as part of an application for development. The results suggest that the higher ground south of the ditch was augmented in the medieval, and possibly Roman, periods by dumping, with the low lying land north of the ditch remaining prone to flooding. In the post-medieval period the build up of material across this northern area presumably led to the need for a formal drainage ditch to be constructed.
