This may be a dumb question, but I have a project that falls under Case 3 - provide vegetated open space equal to 20% of the project's site area. I can't find any credit language that says whether the site area includes the building footprint or not. Other open space requirements in both SS5.1 and other options of SS5.2 are pretty clear about whether to include or exclude the building footprint, but this option doesn't seem to have a clear distinction. My project is on a very tight urban site that is primarily made up of pedestrian hardscape/ vegetation, but it comes nowhere close to 20% of the overall site if the footprint is included. Am I missing something?
