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 D and G Trimble of APS. A ditch was revealed that contained a significant quantity of Middle-Late Iron Age pottery. Further features found included additional ditches and a pit, all of which contained burnt flint and evidence for ironworking in the form of furnace lining, slag and hammerscale - both flake and spheroidal. The results are highly suggestive of an Iron Age domestic settlement site with associated metalworking being present in the vicinity, which, if confirmed by more extensive investigations, could potentially be of regional significance.
Soil stripping, mapping and sample exercise by J Wright of COT revealed three features, all of which contained charcoal. Two contained oak and the third contained alder/hazel fragments, burnt at a high temperature and exhibiting evidence of probable in-situ heating/burning, and probably represent the remains of burnt tree stumps associated with woodland clearance. Radiocarbon dating of the alder/hazel suggests such clearance occurred in the Late Bronze Age or Early Iron Age.
Evaluation by A Taylor of TVAS. Two distinct clusters of pits and postholes were revealed. One cluster produced material dating to the Middle Bronze Age and included fragments of urns from the subsoil suggesting the former presence of a cremation cemetery in the area. The second cluster of features did not produce conclusive dating evidence. A third area of the site contained evidence for a more dispersed series of features, which were dated to the Early Bronze Age, Iron Age and possibly Saxon periods, as well as a series of undated linear features.
Programme of investigation comprising evaluation, excavation and a watching brief by D Saxby of MOLA. Evaluation revealed evidence of Iron Age and Saxon activity in three areas of the site, with the subsequent excavation targeting these areas. Within the middle of the site a 0.4m-thick layer of sand was revealed that produced 1544 Early Mesolithic flints including microlithic flint points, microburins and at least four core adze fragments and a scraper (c 9600–7600 cal BC).
Oxford Archaeology South (OAS) was commissioned by Andrew Josephs Ltd, on behalf of J and J Franks Ltd, to undertake an archaeological evaluation of land at Mercers Farm, near Nutfield, Surrey (centred on TQ 3050 5200) ahead of proposed mineral extraction. The work was undertaken between 3rd - 27th January 2012. A total of 94 trenches were excavated across the site. Evidence was found for activity from three main periods: the earliest spanning the late Bronze Age to early Iron Age; medieval agricultural use; and post-medieval activity.
The excavation by Greg Priestley-Bell, revealed a large number of archaeological features which ranged in date from the Late Bronze Age/Early Iron Age to postmedieval/modern periods. The majority, however, were dateable to the Iron Age and are described below. Details of the post-medieval and modern features are housed with the archive.
Test pitting by C Hayward of SyAS, produced a small quantity of pottery of Late Bronze Age, Middle Iron Age and late Roman date. (458)
Geophysical survey in 2014 by A Sassin and D and A Graham of SyAS on a site first noted by J Hampton on an aerial photograph. The survey confirmed the presence of a probable Late Iron Age/early Romano-British farmstead enclosure. Roman roof tile and pottery was noted during the survey and coins and other objects of Roman date from the same area have been recorded by the Portable Antiquities Scheme.
