Geophysical survey carried out from 2011 to 2012 found evidence of a number of geophysical anomalies in Bourne Park. To the north of the investigated area were a number a anomalies that were interpreted as landscape features associated with the earlier history of Bourne Park.

From the report: "In the northern part of Field 1 west there were dense dipolar anomalies. On the surface there was a dense spread of flint nodules [20], although there could be rectilinear features within this area, there was such a large amount of iron both on the surface and buried (e.g. a long fence runner, fig. **) that they are too obscured to interpret. A quiet area separates [20] and [21], which could indicate a possible terrace associated with the building of Bourne Park House and the creation of the landscaping which included the artificial pond c. 1846. Other linear dipolar anomalies [25] and [26] are likewise separated by quiet areas and appear to be aligned both to [21] and to Bourne Park House,
further supporting the likelihood that they are remnants of landscaping, such as ha-ha walls. This area appears to be bounded to the south by a perpendicular dipolar anomaly [28]. Within this ‘enclosure’ (‘Enclosure 1’) are four subrectangular dipolar anomalies [22], [23], [24], and [27]. Parch marks in satellite images from 2003 (Google Earth) show a complex of linear and rectilinear features in this area.
Outside this ‘Enclosure 1’ to the south/south-east are two dipolar anomalies [29] and [30] seemingly associated with linear feature [28] which possibly represent ornamental buttresses of a brick wall."(1, 2, 3)
