LEED boundary changes permitted?

we will be preparing our ND project for Stage 2 certification in the course of the next few months and we have the LEED boundary pretty much staked out. the developer has just announced that they may look at purchasing a further piece of land at some stage in the future, where the idea would be that it will be incorporated into the overall ND project. would we be allowed to change the LEED boundary once we get to Stage 3 certification, provided that there are no major changes to the overall LEED ND goals that we are committing to in the Stage 2 application? many thanks!
