• Further refine formation surfaces by addition of faults.
• Thickness data are based on true formational thickness values, using boreholes containing formational contacts. It would be useful to incorporate all boreholes that proved a minimum thickness of a chalk formation to ensure that the surfaces are constrained by these depths.
• Incorporate data from boreholes where Chalk formations have been coded as combined units, for example, LSNCK (= Lewes Nodular, Seaford and Newhaven Chalk).

• The Borehole Control layer can be further enhanced by scoring the buffers (e.g. 5 = Very High and 1 = Very Low, as used in Geosure and SuDS) and then appropriately adjusting the buffer scores where they overlap.
