Watching brief by S Mead of MoLAS, for Sandville Properties, following on from evaluation of the site in 1997. Both this evaluation and investigations at the adjacent Cargo Point development in 1997 had revealed a number of features of possible prehistoric and post-medieval date. The watching brief demonstrated that the majority of archaeological activity was concentrated at the northern end of the development site, where what appeared to be a series of boundary or roadside ditches were recorded. These ditches were also seen on the adjacent site and are thought to be of 18th century date.

Watching brief followed by excavation by J Stevenson and G Hayman of SCAU, on behalf of Henry Streeter (Sand and Ballast) Ltd, in advance of mineral extraction. An isolated Neolithic feature was revealed, together with a variety of waterholes, pits and postholes of the middle Bronze Age, and evidence for a field system of Roman or earlier date.

Evaluation by M Dover of SCAU, for Spelthorne Housing Association, in advance of residential development. A shallow gulley containing Late Bronze Age pottery was revealed in two of the trenches. A subsequent watching brief on the development revealed no further features or finds of archaeological interest.

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

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).

Evaluation by J Lovell of Wessex, for Frogmore Developments Ltd, revealed a truncated ditch of probably mid to late Iron Age date, and a second, undated ditch. A number of residual flints of Neolithic to Bronze Age date were also recovered.

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.

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.

Evaluation by D Dobson and D Killock of PCA, for Crest Homes, revealed evidence dating from the post-medieval period to the present day. One trench produced Bronze Age flintwork and a late 12th century pit. Further work revealed a truncated ditch aligned roughly east to west, the fills of which contained a sherd of Mid-Late Saxon pottery and one dating to the 12th century. This feature is likely to be the remains of a field or enclosure boundary.

Evaluation and excavation by S Weaver and J Saunders of TVAS, for HBG Properties, of a site to be redeveloped for warehousing, did not reveal evidence for the barrows mentioned in this vicinity in the Merstham boundary charter of 947 AD. The evaluation did reveal a number of dateable pits and ditches indicating the presence of a late Iron Age / early Roman settlement. One of the features was initially thought to represent part of a curvilinear boundary ditch, but the subsequent excavation illustrated that this was one of two rectilinear ditches on the site.
