Field walking in advance of gravel extraction, by Graham Hayman of SCAU for Greenham Construction Materials Ltd and Tarmac Roadstone Ltd, revealed concentrations of struck flint of Neolithic or Bronze Age date. A wide variety of tools was represented, including scrapers, awls, burins and arrowheads, and the presence of cores and hammerstones, as well as a large number of waste flakes, indicated that flint working was taking place in the vicinity.

Observation by S P Dyer for SCAU and the National Rivers Authority of flood defence improvement works located no artefacts of archaeological interest but added to knowledge of the area between the gravel 'islands' on which Staines stands. (282)

A watching brief on groundworks at the Town Hall and some excavation was carried out by P M G Jones of SCAU for Spelthorne Borough Council. This confirmed that the building lay over medieval and Roman near-shore muds and silts which were sealed below 16th-17th century levels, probably representing foreshore reclamation. A reed peat filled feature of 15th century date was recorded, which contained numerous cut offs of wood and scraps of leather. The earliest buildings on the site appear to be late 15th or 16th century in date.
