Should I include loads of soil, stone, pipe bedding materials, underground pipe, catch basins or other site work materials to the total cost of materials? Credit requirements say, "Include materials permanently installed in the "project". Does "project" mean only the physical building or outside our building like the concrete drive?
If they do contribute, can stone and soil be counted as regional materials? Can all concrete be counted as recycled or regional materials then or is it just Fly Ash that's recycled in concrete?

Matthew - Please read this post regarding what CSI MasterFormat Divisions and Sections are included in LEED 2009 for the MR credits - http://www.leeduser.com/credit/NC-2009/MRc4?all-comments=true#comment-46523. Do you have a Reference Guide? If not, you need one. The CSI Divisions and Sections are listed in there.
Project means the area within the LEED Project Boundary (your LEED Site) but then you have to overlay the allowed CSI MasterFormat Divisions and Sections for the MR credits.
Stone can be regional as it is specified in Division 04. Depending on where soils are specified may allow them to be included. For instance, topsoil placement and grading would fall under 32 9X XX and hence be included in MR calculations. But Soils for Earthwork would fall under 31 05 13 and would not be included.
Concrete can be regional and its fly ash can be recycled. You need to review the Supplementary Cementitious Materials section of the Reference Guide (First Edition, Page 373) to get the most value of the fly ash as you get to take its recycled content value based on the mass of the cementitious materials only, rather than on the entire concrete mix.
