Waste generated outside LEED boundary

I have the same question, but with a different perspective.  If some assembly of materials (such as the building of racks), which is usually done in the laydown area on-site, is done off-site for a project, do we need to count the waste associated with that?  I have a project where the LEED boundary is pretty tight to the building, so as not to overlap with other projects' boundaries (existing and future).  So the laydown area and assembly area are very close to the site on the owner's property, but are not actually within the LEED boundary.  It seems waste associated with these materials (and their assembly) is usually done on-site, and would therefore be tracked.  We DO have the ability to track this waste separately from other off-site wastes related to the existing buildings.  Should we include this waste in our LEED calcs?

We have had experience with "unusual" boundary situations for Construction and Demolition Waste Management.  In one case it was a LEED campus issue.  In another it was a combined LEED/SITES project.  Without getting into the details of those cases I suggest you write up a plan/approach that works with the team, stress why it is a benefit and accomplishes a greater good (goes farther) than the alternative (in this case  goes beyond the basic LEED requirements) and ask for approval of that process with your LEED Coach.  It seems the strength of including off-site materials from an adjacent (non-LEED) project is that more will be recycled and less land fill will take place than if you only included the materials from within the LEED boundary.

You would not be required to include diversion from off site activities in your C&D Waste Management Plan.  However,  There is a "community benefit" of doing so if you are able to, even if only in specific cases.   I suggest you write up a plan/approach that works with the team, stress why it is a benefit and accomplishes a greater good (goes farther) than the alternative (in this case  goes beyond the basic LEED requirements) and ask for approval of that process with your LEED Coach. We have had success in this approach for unusual circumstances where we can show we are exceeding the basic LEED requirements.  You (and also in Cindy Quinn's case above) may even wish to approach this as an Innovation Credit.
