NHER 63368 (Negative evidence record) - Site with no evidence for archaeologically significant remains

2004-2005. Desk-based Assessment.
Archaeological assessment of western route options for Norwich Northern Distributor Road.
See reports (S1) and (S2) for further details.

April 2012-August 2013. Geophysical Survey.
Magnetometer survey on proposed line of Norwich Northern Distributor Road (Block 3).
This survey revealed little clear evidence for sub-surface archaeological remains. Although a range of anomalies were detected these were thought to be of predominantly agricultural or geological origin. The discrete dipolar anomalies detected are typical of the responses caused by the presence of modern ferrous debris.
A linear dipolar anomaly indicates the line of a modern service pipe running parallel to the field boundary. This pipe would appear to correspond with a cropmark feature mapped in the field to the south-west (NHER 52387).
See report (S3) for further details.
Previously recorded under NHER 50494.

May 2014-January 2015. Geophysical Survey.
Magnetometer survey on updated proposed line of Norwich Northern Distributor Road (Area F4).
This survey identified no anomalies of obvious archaeological significance.
Various discrete dipolar anomalies are likely to have been caused by ferrous debris in the topsoil.
A broad linear band of high magnitude anomalies is thought to represent changes in the underlying drift geology.
See report (S4) for further details.
