The people delivering the new school planned for Elsea Park are fighting against the clock to be open in time for September 2014 after its planning application was deferred.
The planning application submitted by Lincolnshire County Council was deferred at a meeting of the county council planning and regulation committee on Monday following concerns raised about access to the proposed site.
The application will go before the committee again at its next meeting on September 2 after planning officers have looked into whether there are alternative access options for the school located off Sandown Drive.
Three residents of Sandown Drive object to the application which gained outline planning permission in 2001.
This week Bourne Abbey Primary Academy was officially selected to run the new school by Secretary of State for Education Michael Gove after a recommendation from Lincolnshire County Council.
However a delay in an already tight development schedule has cast doubt on whether the site will be ready to open to one form of 30 reception pupils by September 2014.
Bourne Abbey Primary Academy chairman of governors John Kirkman said: “We will do everything in our power to get this school open in time for a reception class in September 2014.
“It is inconvenient for us but the biggest inconvenience is with the parents and that could be a major problem.”
Parents will need to select which school their children go to by January 2014.
Mr Kirkman fears for the project could fall behind schedule because tenders for contractors to build the new school cannot be sent out until permission is granted.
