Heritage Trees

I would welcome other perspectives, but I would say your chances are not that great.Basically, you are saying that you had a uniquely difficult site relative to meeting the requirements of SSc5.1, and the lengths that you went to earn SSc5.1 and the specific techniques you used are worthy of special recognition through IDc1.USGBC has had a clear policy of not awarding IDc1 points for projects earning an existing credit in a unique way, for example, using a special HVAC technology to earn EAc1. This situation seems analagous—subsitute heritage trees for a HVAC system, and SSc5.1 for EAc1.From the perspective of LEED, a situation like yours is exactly why SSc5.1 exists. It doesn't call for creation of a new LEED innovation credit. It's up to USGBC/GBCI, of course—you could always try your luck by submitting.
