Evaluation by S Thompson of WA within the grounds of Sutton Place revealed plough scars of likely post- medieval or modern date and recovered a small assemblage of medieval pottery from the topsoil. It is probable that differences in the underlying geology accounted for a linear feature observed in aerial photographs dissecting the site.
Excavation and watching brief by M Collings of WA in advance of flood protection, landscaping, tip remediation and redevelopment alongside the Hoe stream of areas identified as being of potential interest during evaluation of the site in 2010. The excavation confirmed the presence of postholes, gullies and ditches. Owing to the lack of secure archaeological finds, it was possible to date only two ditches: one to the Early-Middle Iron Age and a second to the post-medieval/modern period.
Evaluation by O Good of WA revealed a post-medieval ditch, a number of undated shallow pits and several modern field boundaries.
Excavation by M Williams of WA revealed evidence of a substantial walled structure possibly associated with two parallel boundary walls, and the remains of a possible fish pond, 200m north of the inner gatehouse of Bletchingley Place, the property given by Henry VIII to Anne of Cleves as part of her divorce settlement. The suggestion is that the structure may be a northern gatehouse leading from the walled gardens surrounding Bletchingley Place into the deer park to the north.
Evaluation by J Powell of WA revealed features within twenty of the 54 trenches. The majority of the features were ditches and gullies, orientated predominantly on a north-west to south-east alignment, and forming part of widespread field systems. The features were generally shallow, which may suggest truncation from previous agricultural activity. A small number of possible pits and postholes were revealed, but no evidence to suggest the potential for settlement or significant levels of activity. Relatively little datable material was recovered.
Evaluation by N Brennan of WA within four areas of a proposed mineral extraction site that appeared to contain a possible 19th century mill site and a possible sub-circular enclosure. No evidence of the mill site was revealed, but the evaluation confirmed the presence of the large sub-oval enclosure on a slightly raised area of ground. The enclosure survived as a ditch, with no traces of a bank, and was identified in three of the evaluation trenches. The ditch contained a small quantity of Middle-Late Bronze Age pottery.
Evaluation by S Thompson of WA. A ditch containing Late Bronze Age pottery and a waterlain soil deposit characteristic of either a river channel or flood plain suggest the site is located within a well-preserved and rich prehistoric landscape.
Evaluation by Dave Britchfield of WA revealed evidence of previous terracing and grading across the site, with a well-developed subsoil completely absent, but no finds or features of archaeological interest.
Historic building assessment by J Thomson of WA of a former pumping station and adjacent cottage original to the c 1900 construction of the sewage works.
Evaluation by D Freer of WA within the Scheduled hillfort revealed evidence of modern activity but no finds or features of archaeological interest.
