Excavation by S P Dyer for SAFG in advance of redevelopment revealed a continuation of the multi period site at Petters Sports Field. Prehistoric worked flints, BA pottery, an IA terret (identified by the BM), a few sherds of probable IA pottery and mixed RB pottery were found in a buried river channel. The previously postulated RB road could not be located and the evidence suggested that it had not existed.

Excavation by G N Hayman for SCC and Esso Petroleum revealed further evidence for the Saxon period cemeteries previously excavated. Another 12 inhumations were found, five clearly pagan, of which three had iron knives, one also having two bronze pins. The other burials were probably executions; one in particular seemed to have had hands tied behind the back. Some 15 sherds of prehistoric pottery, some at least probably Neolithic, were found in the excavation. (241) The laying of a water main along the lane to the south was monitored by L Le Mottee, but nothing of interest was observed.

Excavation by R J Poulton for SCAU and SCC (County Engineer's Department) in advance of the construction of the relief road showed that post-medieval evidence had been removed by the construction of a car park. Evidence of medieval occupation survived, including various 12th/13th century pits apparently indicating the first settlement in this part of the town, although late Saxon pottery was also discovered and must indicate nearby occupation. (257; report in SyAC 85, 177-186)

Evaluation of the site for a supermarket by R J Poulton for SCAU and the Co-operative Wholesale Society. Archaeological features were revealed and then formally excavated. The pottery recovered dates from the 9th to the 13th centuries and the features uncovered seem to indicate the presence of a farmstead on the site during that period. (257)

Excavation by J Harte and H Waterhouse for Bourne Hall Museum and NAS [now EEHAS] in the bed of the lake which had become dry. Preliminary examination in 1990 produced 38 1st to 3rd century Roman coins from one sector. A trench indicated that dredging had removed most material above the natural Thanet Sand. Gravel-filled pockets in the sand were however found to contain animal bones and IA, RB or Saxon pottery. Various walls, mostly presumably earlier retaining walls for the lake bank, were also noted. (265). It may be suggested that the Roman coins were offerings at the original spring.

Evaluation and subsequent formal excavation in advance of the Runfold diversion, part of the Blackwater Valley Route, by Graham Hayman of SCAU for SCC, recorded a range of features including ditches, postholes, pits and a small four-post structure. Provisional examination of the pottery suggests that features of Neolithic, Bronze Age, Iron Age, Roman and medieval date were present. A few sherds of Saxon pottery were also discovered. (273)

Observation by G R Pattison and P M G Jones for SCAU of trench cutting for cable TV revealed part of an Anglo-Saxon inhumation with possible grave goods including an iron spearhead and fragments of a pot with rosette stamps. Other finds from the general area included one probably IA sherd, various fragments of RB pottery, mostly 4th century, and some further fragments of Anglo-Saxon pottery.

Evaluation by B Langton of the Cotswold Archaeological Trust for Wates Built Homes Ltd recorded a scatter of mainly Neolithic flints and a number of features of Bronze Age date on this former racecourse adjacent to the Thames. More detailed excavation of the site was subsequently undertaken by P Andrews for Wessex Archaeology, which identified multi-period activity on an area of higher land.

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.
