A watching brief was maintained by M Dover of SCAU, for Thames Water Utilities, on the construction of a replacement pipeline to the reservoir, where work was not along an existing road. The route passed close to the church at Hambledon, and pieces of medieval and post-medieval tile, and some post-medieval pottery were recovered from this section, although no features were noted. The section through the field boundary south of the track to Upper Vann Lane suggested that a ditch had preceded the current boundary bank, but no dating evidence was recovered. Little else of archaeological interest was noted. (321)
