We asked Ben Geering , Head of Planning at Shepway if he would consider publishing the correspondence between the applicant and his department and this was his reply:

“We do not usually publish correspondence between case officers and applicants online however have no concerns in doing so – I will ask the case officer to make the email request for additional information public on the application file.
Regarding the viability information – this is part of the request for further information we are waiting a response to.
Once further information is received the application will be reconsulted on.”
