A survey of 14 machine-excavated geotechnical test-pits (each c.2.0 x 0.5m in size), located on and around the area of the proposed southern sheltered housing block of the Balkerne Heights development (Salter Court, 1 to 81), defined Roman deposits across the whole of this area of the site. Most of the deposits consisted of Roman soil accumulation layers and fills of deeper features representing pits or graves; all except two contained Roman deposits between 0.8-1.2m thick. A substantial Roman feature in the south-east corner of the development (in TP2, TP101 and TP104) probably represents the town ditch; in TP104, the Roman fill extended in excess of 2.0m. Close to the town ditch, part of a stone and mortar Roman building foundation was observed, and on the central-west area of the site, part of a Roman street or lane was recorded. Except for the fill of the town ditch, which was not bottomed, the identified surviving Roman deposits, including fills of deeper features such as pits, averaged about 0.8m in depth. <1>
