Archaeological evaluation was carried out in Plot F of the Chelmsford Business Park in advance of the construction of commercial premises. Plot F is located within an important and extensively investigated landscape that contains Neolithic and Bronze Age enclosures and settlement, an Early Saxon cemetery and a Late Saxon manorial complex. The Business Park site was formerly the grounds of a late 17th-early 20th century residence known as Springfield Lyons. Four trial trenches were located within the 2850sq m site. Only one trench contained archaeological remains, those of a single field ditch of post-medieval date. Widespread disturbance, in the form of the deposition of a significant thickness of made-ground and redeposited topsoil, was identified to have taken place. This is likely to have been the result of Plot F having been used as a construction compound during earlier phases of the Business Park development. The results confirm that the land outside of the Neolithic enclosure and north of the Bronze Age and Saxon settlements was not extensively utilised, except perhaps as farmland. The recorded ditch may relate to parkland land use surrounding the historic residence of Springfield Lyons.
