Watching brief by G Hayman and J Stevenson of SCAU, for Greenham Construction Materials Ltd., during the construction of a lake. Athough no features were discovered, this barrenness is likely to be a result of repeated flooding scouring the landscape and effectively washing such evidence away. There was certainly past activity on the site, as evidenced by the number of finds, albeit redeposited, ranging from the Neolithic to medieval recovered during the watching brief.

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 Grove of Wessex, for MEPC UK Ltd, in advance of redevelopment. Earlier Roman activity (1st-2nd century) was found to be restricted to higher land at the southern end of the site. Here, a number of refuse pits and a series of gulleys and ditches were revealed, as well as two occupation surfaces and a possible oven. An episode of flooding separated these features from those of mid Roman date (2nd century), which were also concentrated on the higher ground.

Watching brief by P Jones and J Robertson of SCAU, for Wizard Inns, during work on an extension and improvements to the Blue Anchor. The nature of the foundation trenches, 3m deep and 0.85m wide, meant that they were unsuitable for proper archaeological recording to take place. Pottery of Roman (late 1st - 2nd century) date and a small, possibly, Roman coin, as well as late medieval (15th century) pottery, animal bone and tile, were recovered from the spoil heap.

Evaluation and watching brief by J Stevenson of SCAU, on behalf of the church, of part of the site for a proposed extension. The trenches were restricted to the area outside the churchyard; they revealed considerable disturbance, presumed to represent landscaping in the 19th century. The watching brief on remedial works on the east end of the Chancel revealed the foundations to be constructed from mortared chalk rubble, sitting on the natural gravel, with no obvious signs of earlier structural remains. A number of both articulated and disarticulated human remains were also revealed.

Evaluation and excavation by G Hayman of SCAU of Phase 7 of this mineral extraction site, for Greenham Construction Materials Ltd, revealed a variety of features; the quantity of finds associated with many of these is indicative of settlement activity. Most features were revealed on an area of marginally higher ground. They include a very large ditch, possibly forming an enclosure around a settlement. The finds appear to be of Bronze Age date and probably relate to the settlement of that date found in previous phases (4E and 6B).

Following evaluation of Phase 4 of this mineral extraction site in 1997, by G Hayman of SCAU for RMC Aggregates, a watching brief was maintained by SCAU on the stripping of the area. A couple of features of Middle Iron Age and Roman date were revealed, but the main features of interest appear to be Bronze Age. These features included a round house with an ancillary gulley and an enclosure ditch. A pit within the round house included part of a cup decorated by slashes made with a flint blade or flake.

Excavation and a watching brief by D Hopkinson of AOC, for Countryside Properties (Commercial) PLC, of the site of Phase 5 of the Chertsey Revitalisation Scheme, following an evaluation in 1997. The earliest evidence revealed was a series of intercutting Saxo-Norman gullies, apparently demarcating an enclosure extending to the north and west, with an opening in its south east corner. A series of pits and ditches of 14th - mid 16th century date appear to be the next phase of activity. Two major ditches of this date defined plots alongside Guildford Street.

A watching brief was maintained by J Robertson of SCAU, for RMC Aggregates (UK) Ltd, on soil stripping in advance of mineral extraction. The site revealed no features of archaeological interest, although stray finds recovered include two struck flints and a sherd of Saxon grass-tempered pottery. Fragments of burnt flint and pieces of medieval and post-medieval tile were observed over much of the stripped area.

Evaluation and excavation by J Stevenson and G Hayman of SCAU, for Gleeson Homes, in advance of residential development on the former hospital site. The evaluation was aimed at testing the results of an earlier geophysical survey, and revealed evidence of prehistoric and medieval activity. The subsequent excavation revealed a scatter of prehistoric features, including a ditch and two small pits. One of these produced a quantity of flint debitage, seemingly of Mesolithic date. Neolithic and Bronze Age flintwork was also recovered, while the ditch and other pit were of Bronze Age date.
