Complicated Open Space/Habitat Protection, LEED Boundary

We are attempting to achieve exemplary performance in open space and protection of habitat. The project is located, and a portion of a secured (fenced) industrial park setting w/ the back property line backing up to an existing residential area. The LEED boundary is a "L "shaped tract that includes all site improvements associated w/ the LEED building and a perimeter strip around two sides of the property lines including the wooded back side adjacent to the residential area. My concern is the reoccurring comment "don't gerrymander the boundary" There are other buildings on the site that are not to be certified and our LEED boundary runs along (gerrymandering, but not including) the hardscape parking areas for the other buildings, taking credit for all vegetated areas in a contiguous designated area. Additionally we are indicated 2 future buildings adjacent to our site and claiming/preserving the property behind them along the back property lines, again wooded, adjacent to residential property and contiguous at the elbow of the "L" shape. Sorry to be so long winded, however it's been fairly complicated to come up w/ a solution that the owner can accept. Also does anyone have a good example of the language needed for the owner's acceptance letter? Thanks
