Report on a programme of fieldwalking conducted on ten fields to inform the proposed construction of a large new residential development on land to the south of Grantham. Three fields were either in pasture or overgrown and could not be walked. Two loose clusters of Roman pottery sherds, possibly indicative of settlement or agricultural practice, were identified in the northwest and southwest of the surveyed area. A small number of Prehistoric worked flints were also recovered from across the site, including a Mesolithic/Early Neolithic blade core and a disc scraper.
