Following geophysical and aerial survey a programme of 700m of evaluation trenching identified prehistoric ditches and postholes that correspond with cropmarks illustrating a coaxial system of ditched field allotment of a probable prehistoric date. This was confined predominantly to the western third of the proposed development area, and with only minimal expression having undergone significant post-Medieval truncation through experimental agriculture. A palaeochannel was identified through magnetometry, and was shown to predate human activity
