stones found onsite & reuse of shutters for use in project

Hmmm. I will break it down the best I can: . . 1. I am assuming that you will use the stone as masonry, paving, or for some other purpose covered in the CSI Divisions and Sections applicable to MRc3 through MRc7. . . . . MRc2: Land clearing debris (soil, vegetation, and rocks) cannot count toward MRc2, but if these stones are long-ago discarded cut masonry, USGBC might make an exception. I would submit an inquiry to USGBC. . . . . MRc3: I think that reusing the stone may qualify as “Reuse.” The trick here is estimating a value for the stone. MRc3 also places some limitations on reusing materials recovered from and reused on the same project site. . . . . MRc4: The stone would only count as Recycled if it were reworked or remanufactured into a different product. . . . . MRc5: If the stone counts toward MRc3 or MRc4, it will also count as Regional under MRc5. . . 2. Shutters: CSI classifies exterior shutters in Division 8, so they can count toward MRc3 through MRc7, but interior shutters may not count because they are Division 12 “window treatments". . . . . MRc1.1 Shutters cannot count toward MRc1.1 because they are non-structural. . . . . MRc1.2 If they are interior shutters, you may be able to count them toward MRc1.2. . . . . MRc2: You may be able to count the shutters toward MRc2, but there are limitations on “double-dipping” if you try to count them towards other MR credits. . . . . MRc3: As noted above, MRc3 limits reusing materials salvaged on-site for the same purposes as originally intended. . . . . MRc4: No. . . . . MRc5: If the shutters count toward MRc3, they will also count as Regional under MRc5. There are so many ins and outs to material reuse that you may want to repost some of these questions to LEEDuser’s MRc1.2, MRc2, and MRc3 forums. The experts on these forums may be better versed on blending these credits.

Reviewing the reply above, it sounds like crushing existing rock on site to use as stone base could count as Recycled Content because the rock is being re-worked into a new product. For approximate value in MR Calculator, they would use a quote for the same quantity/quality of stone from a regional source.
