It follows the response to South Kesteven District Council's public consultation in October last year on proposals for the Rectory Farm site, which is earmarked for more than 1,000 homes.
The main change concerns access to the site from Barrowby Road, with a proposed roundabout being replaced by a number of individual junctions.
The council is now inviting comments on the revised brief during a second consultation period that runs until February 12.
The Cabinet Member for Growth, Cllr Helen Goral, said: "One of the key points for the public consultation were the site access points. It was clear that there were concerns about the roundabout, which we have listened to and acted on.
"This is a great example of the consultation system having a positive impact on an important planning document."
The completed planning brief will provide guidance for landowners and developers.
Rectory Farm is the second phase of the North-West Quadrant development, between Barrowby Road and the East Coast Mainline. There are 1,800 homes being built in the first phase, known as Poplar Farm.
A copy of the planning brief can be seen at the Council Offices, St Peter's Hill, Grantham, in Grantham Library, and online at www.southkesteven.gov.uk/rectoryfarmconsultation
Comments should be sent to Development Management Team, The Council Offices, St Peter's Hill, Grantham, NG31 6PZ or by email to email@example.com
All representations received by the end of the consultation, and any issues raised, will be taken into account before the brief is finalised.
