Site Event/Activity record ESF18808 - Evaluation - Eastgate Barns

A series of trenches was excavated ahead of mixed residential and commercial development. Twenty one trenches were excavated equaling 1062sqm, sampling c.6.8% of the site. The site slopes down to the River Lark, which flows just beyond the western side of the site. The change in level is about 5m and there is a slight step in the slope. This change is a reflection of the underlying geology where the chalk of the solid geology is close to the present ground surface above the contour, but below it an increasingly deepening layer of homogenous fine clayey silt covers the chalk. The silt is either a hill-wash colluvium or glacial till, which was between 0.5-0.7m deep in the trenches on the western edge of the site (S1).
