In the LEEDuser FAQ's above it states, "Can a project designate open space off-site and not within the LEED project boundary to meet the credit requirements? Answer: To date, we are not aware of a project being able to achieve the credit requirements by allocating open space outside of the LEED project boundary. The credit requires the open space be adjacent to the building and within the project boundary. However, this approach has been used to meet SSc5.1 credit requirements."

However, in the 2009 BD+C Reference Guide on page 86 it states, "In a campus setting with no local zoning requirements, open space that is equal to the building footprint can be considered separate from the project site, as long as the open space is preserved for the life of the building."

I am wondering why the FAQ's state that the open space needs to be within the project boundary? Thanks!
