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 K Ritchie of Wessex, for MEPC UK Ltd, revealed approximately two metres of garden soil sealing the truncated remains of three intercutting ditches running parallel to and 30 metres north of the High Street. Finds recovered from the ditch fills date the features to the first or second centuries AD. The ditches are thought to represent boundaries separating the street frontage settlement and near backland activity on the south of the gravel island, from the less intensively occupied far backland margins to the north.

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 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.

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.

Fieldwalking and topsoil seiving by P Harp and Plateau has recovered a large number of worked flints of Mesolithic, Neolithic, and Bronze Age date, some Bronze Age, Iron Age, Romano-British, and medieval pot, and a medieval knight finial fragment. (317, 319, 323, 324)

Evaluation by T Howe of AOC, on behalf of Pfizer Ltd, of a site to be redeveloped for offices. The evaluation revealed features possibly associated with former garden layouts. The westernmost trench contained the remains of an extremely large ditch, which contained no dating evidence; a sherd of abraded Roman greyware pottery was collected from the fill during machining but this is likely to be residual. In the southernmost trench brick built foundations, probably 19th century in date, were revealed.
