The Hampden Fields Action Group is appealing for donations to help fight the revised application for 3,000 homes near Bedgrove and Weston Turville.
The planning application – which now includes provision of a southern link road – was submitted to the district council last week.
The action group successfully fought against the original Hampden Fields plans with the help of donations from the community.
In a letter to supporters sent out this week, it said the proposals were ‘almost exactly the same’ from those which were rejected by a government inspector last year.
It added that claims about the benefit of the link road were ‘exaggerated’ with no evidence to support it”
The group adds: “The Hampden Fields Action Group reformed after an overwhelming response from local people who are rightly outraged by a developer who simply chooses to ignore public opinion.
“Once again, we are asking for the support of the public in raising £75,000. Without the public support we do not exist.”
Last week Bedgrove councillor Tom Hunter-Watts (Independent) said: “I think opposition will be futile and stand absolutely no chance whatsoever.”
The application is now on the AVDC planning website, reference: 16/00424/AOP
