On site + Off-site restoration

Our project is redevelopping a contaminated site (whole city block), which is part of a larger urban area belonging to the same owner. Within our project boundary and outside of it, we're creating 3 green corridor to promote vegetation and wildlife biodiversity, with native plants. With the density we're trying to achieve, we are slightly short of the 10% threshold, so we would like to include the area of the green corridors outside of the LEED-ND site limit to achieve the threshold. We know there was an ID point awarded for a LEED-ND pilot, that restored 25% of the footprint outside the boundary, but we haven't found any info on a different way to achieve this credit in 2009 or v4. [http://www.usgbc.org/sites/default/files/LEED%20ND%20ID%20_CIR%20catalog_Public_2015-2.pdf] So we have 2 questions : 1. As anyone tried to include green roofs planted with native vegetation to contribute to the credit? 2. As anyone tried to include green spaces outside the project boundary to contribute to the credit?
