An archaeological evaluation was undertaken by Tom Collie, at the proposed Motorway Service Area, Cobham, Surrey. The work was undertaken between 8th and 21st May 2007 on behalf of Gifford. Thirty two 50m by 2.5m trenches were excavated. The evaluation revealed limited archaeological evidence. Of the thirty two trenches excavated, the following twenty were archaeologically negative: trenches 3, 5 - 7, 12 -19, 22 - 23, 25 - 29 and 32. Trench 1 only contained a modern pit associated with refuse dumping.
Fieldwalking by S Stevens of ASE recovered prehistoric, Romano-British, medieval and post-medieval material in varying quantities, mostly from the southern part of the examined area. There was some correlation between the distribution of the Romano-British and medieval finds and the location of potential buried archaeological features identified during a concurrent geophysical survey.
Evaluation by D Britchfield of WA identified evidence for prehistoric activity on or in the vicinity of the site in the form of residual burnt flint and a flint blade of Mesolithic or early Neolithic date. A small quantity of medieval pottery was recovered from a tree-throw hollow but a small pit contained no datable material. Features such as a grubbed-out hedgerow and an infilled ditch indicated that the landscape had been altered in the recent past.
