An archaeological monitoring exercise and evaluation by Paul Riccoboni, was maintained on land at Cleveland Lodge, Westhumble Street, Westhumble, Dorking, Surrey (NGR 1670 5190) prior to the construction of a housing development with associated roads and car parking (Planning reference: MO/2006/1607/PLAMAJ). Four site visits were made by supervisory staff from ASE between the 30th May 2007 and 14th August 2007. Archaeological monitoring took place along the line of the temporary road, which traversed the site. Three trial trenches were also excavated across areas designated for housing units (located outside of previously disturbed ground). One possible medieval gully/ditch and one potential posthole were recorded within Trench 1, as well as a 19th or 20th century pit and soakaway. The other two trenches contained no archaeological finds or features.
