Boundaries of LEED ND publicly available & requirements for NC

Dear LEEDuser team, I have two questions for a new building to be built within the area of an existing LEED ND project (or very near). 1. How can the project team know the exact project boundary of an existing LEED ND project, assuming that the project team hasn't been previously involved on that given LEED ND project? From my understanding, the boundaries of LEED ND projects are not publicly available. We are therefore unable to advise our client whether they can pursue the "LEED for Neighborhood Development location" credit. Do we have to get in contact with the USGBC to request for the exact LEED project boundary? 2. Considering that the LEED ND certification has already been granted: what are the minimum energy performance requirements for a new construction project within the LEED ND boundary? According to GIBP2, "for 90% of the building floor area" (..) "New buildings must demonstrate an average 10% improvement" (..) and document building energy efficiency accordingly. From my understanding, this requirement applies to all new buildings to be built within the LEED ND boundary, including for buildings for which the construction starts after the LEED ND certification has been granted. Could anyone confirm this interpretation? Thank you Louis
