Despite inspectors last year recommending that new roads, schools, doctors and dentists should be funded when thousands of new homes are built across the area, the government now looks set to go against this advice.
Hazel Blears, minister in charge of communities and local government, is suggesting a series of changes to the South East plan – a blueprint for the region over the next 18 years.
Her changes would see infrastructure no longer a condition of development.
Instead she is suggesting that councils should perform a test – first seeing if they could make roads less busy by bringing in measures such as tolls or charging businesses to allow their employees to park on their premises.
Only if these two fail is Ms Blears suggesting new infrastructure should be pursued.
She is also suggesting that the target number of homes councils set for sites within their districts should be a minimum, leaving developers free to ask to build more.
The Partnership for Urban South Hampshire, an influential body comprising local council leaders, is furious.
Push chairman Sean Woodward, also leader of Fareham Borough Council, said: 'We've produced enough evidence to support the need for adequate infrastructure investment, which the government seems to be ignoring.
'Quite frankly, if there's no new infrastructure then we do not want any new development.'
Push also has severe concerns about Ms Blears' suggested amendment to house building numbers, making them a minimum or 'floor number'.
Cllr Woodward added: 'Each council is looking at potential sites and setting numbers for how many dwellings could feasibly be built there.
'We set these targets with local knowledge – something the minister doesn't have. It could cause huge problems within districts.'
Leader of Portsmouth City Council Cllr Gerald Vernon-Jackson said: 'You've got to have infrastructure in place first, before any development takes place.
'The government needs to get its act together.'
The department of communities and local government would not comment on the individual amendments but said no decision has been made and a consultation is under way.
Infrastructure is also one of the key demands of The News Save Our South campaign.
