Council member for planning and housing Derek Wilson is writing to communities secretary Hazel Blears after its policies failed a public examination.
The Planning Inspectorate has told council planners that six of the 26 policies will be declared unsound in a report due out this month. According to the council, one reason cited is that its policies do not consider options for green belt use.
Wilson said the inspector has overlooked the 94 per cent of residents responding to the consultation who want to preserve the green belt.
He called for a review of the target for 6,920 homes over the next 20 years outlined by the South East Plan panel. He said the council has permissions in place to meet increased targets over the next five years.
