Evaluation by S Ford of TVAS for the Environment Agency of the area proposed for a flood relief channel adjacent to the River Colne. Most of the trial trenches were negative, but at the northern end of the proposed channel a pit containing burnt flint and a fragment of prehistoric, possibly Bronze Age, pottery was identified. A spread of burnt flint and charcoal adjoining this feature produced a similar sherd of pottery. (319)

Evaluation by G Hayman of SCAU, for Greenham Construction Materials Ltd, of an area proposed for mineral extraction (and a flood relief channel) identified a silty deposit containing worked flint, sherds of prehistoric (probably Bronze Age) pottery and a couple of sherds of Roman pottery, which overlay a buried river channel. (314)

Evaluation and subsequent excavation by J McKinley of Wessex, for MEPC, was carried out in advance of the redevelopment of the estate. The evaluation identified three broad zones within the site: the edge of the town gravel island, a broad alluvium filled channel to the north and, beyond this, a second gravel island. Subsequent work concentrated on the two islands. Excavation on the northern island (centred at TQ 033 719) recorded part of an enclosure/field system of Bronze Age date and another of Roman date, as well as agricultural features from the medieval period.

Evaluation by D Hopkinson of AOC, on behalf of Nicholas King Homes, in advance of residential redevelopment revealed a number of features, including a possible cultivation mark containing a sherd of mid to late Bronze Age pottery. Subsequently an area excavation was carried out by R Entwistle of AOC and a watching brief was also maintained on the development. A small assemblage of Mesolithic flints was recovered, as well as some sherds of Neolithic and early Bronze Age pottery.

Evaluation by G Hayman of SCAU of Phase 5 (and parts of 6A and 9) of this mineral extraction site, for Greenham Construction Materials Ltd, revealed a number of features of prehistoric date. Subsequent area excavation (centred TQ 062 686) revealed a number of small pits and post holes and a substantial waterlogged pit -believed to be a waterhole, all likely to be of Bronze Age date. Two ditches found running roughly parallel to one another, six metres apart, could be the remains of a contemporaneous trackway. (311, 314)

Evaluation and subsequent excavation by R Taylor-Wilson of PCA, for Crest Homes, of this redevelopment site adjacent to the Thames. Struck flints recovered indicate Later Neolithic and Bronze Age settlement in the near vicinity, with some indication of Later Mesolithic or Early Neolithic activity as well. The site was most extensively occupied in the Later Iron Age, when a settlement, probably a small farmstead, was established, the main focus of which was outside the excavated area. The main features excavated were a series of enclosure ditches and numerous pits and postholes.

Evaluation of this site by J Saunders of TVAS, for Prides Crossing Property Ltd and Cardale Developments Ltd, revealed little evidence for activity on the rear of the site except a possible medieval or post-medieval ditch and earlier pit. Towards the street frontage a sequence of medieval deposits was revealed, leading to area excavation. This confirmed the presence of deposits relating to occupation from the 12th century onwards, although the area of the street frontage itself was found to have been destroyed by basementing.

Excavations (centred TQ 063 630) by G Hayman of SCAU, for Ready Mixed Concrete (UK) Ltd, followed earlier evaluation. The work confirmed the presence of Iron Age and Roman settlement; some medieval features were also identified. (314) Evaluation by M Dover of SCAU of Phase 4 of this mineral extraction site (centred TQ 057 635) revealed two areas with some archaeological interest. Both produced gullies or ditches containing prehistoric, probably Bronze Age, pottery. Other features were of post-medieval date. Finds recovered include an obliquely blunted point microlith. (321)

Evaluation and subsequent excavation by J Robertson of SCAU, for Countryside Commercial, of this redevelopment site. Evidence for prehistoric activity was recovered in the form of struck and burnt flint and a probably Bronze Age pot sherd. A sherd of grass-tempered Saxon pottery was also recovered. Well preserved stratigraphy indicated occupation in the vicinity from the late 13th century onwards, possibly associated with the medieval suburb of Styvynton, previously only known about from documents.

A survey of the barrow was carried out by K Pringle for BHRG and SyAS. Examination of the section revealed by the removal of a retaining wall constructed c.1924 revealed no evidence for turf lines. A number of struck flints were recovered from the backfill of the retaining wall and one flake was recovered during the cleaning of the section. Further examination of the barrow revealed that a substantial air raid shelter had been constructed within it. (320)
