Our project is a scientific facility located on a greenfield site in northern Canada. A polar bear fence is essential for the protection of researchers from bear attacks and the facility from bear damage. This 8’ high bear fence is placed on 14” diameter x 5’ deep concrete piles spaced at 8’ over centre. The fence encloses the hardscape and buildings. Every effort to limit site disturbance involving the installation of the fence has been considered. Given the necessity of the fence and it’s robust construction could it be allowed a reasonable offset?

I think your best approach here would be to decide what a reasonable offset is for this fence and propose that to USGBC when you submit the credit for review. It's such a unique project requirement, that your team almost certainly has more expertise than the LEED reviewer on how much area you need to disturb and what you can do to prevent habitat damage. If you put togehter a narrative and diagram showing the dimensions of the pilings and the limits of disturbance and the measures you are taking to keep the disturbed area as small as possible, I bet that will be acceptable.
