The proposed construction of 1,100 homes at Omega Warrington is among the amendments to the council's draft plans for the next 15 years ordered by the Government.
The latest stage of consultation on Warrington Borough Council's Local Plan Core Strategy runs until Monday 30 September.
The original local plan did not specify the number of houses that might be built at Omega, a 575-acre development straddling the M62 motorway at the site of the former Burtonwood airbase.
Other amendments to the draft core strategy include the deletion of a policy which identified land at Appleton, Grappenhall Heys, Peel Hall and Pewterspear Green as potential locations for future housing development.
These locations were to act as a contingency in the event that not enough new homes were delivered on brownfield land within the older, central parts of the town.
Omega Warrington is a joint venture between Miller Developments and KUC Properties, part of Royal Bank of Scotland, in partnership with landowner the Homes & Communities Agency and supported by Warrington Council.
Cllr Terry O'Neill, leader of Warrington Borough Council, said: "The adoption and finalisation of the local plan has moved a significant step closer.
"The need for changes following the examination hearing sessions is a routine part of the process.
"I genuinely believe that those which we have agreed with the inspector will further strengthen a robust local plan which delivers and supports the needs of residents and businesses and will reinforce our growth framework Warrington Means Business."
All consultation documents are available on the council website, with copies also available in all of Warrington's libraries, the Contact Centre on Horsemarket Street and New Town House on Buttermarket Street.
