Count me in with those frustrated with this credit language/ requirements. So I can be confident of our calcs, the local requirements call for vegetated open space to equal 25% of the total developed site area. LEED requires the project to exceed that local requirement by 25% (.25 x .25 = .3125). Therefore, if our site contains 10,000 sf, we achieve this credit by the site containing 3,125 sf of vegetated open space. Correct?

Hi Elliot,If you take a look under Checklists, Design Development, there is a chart explaining the various calculations for each compliance path. I'm not sure which path your project falls under, so I'm not sure if your math is correct.

Not all green fields can count as such. I had a library project within a park setting. No doubt that all those green should count but instead the reviewer asked, "Are those greens not monoculture and does not require regular maintenance?". Of course they must be monoculture (of the same grass kind) and of course they require maintenance (they are not synthetic). So, I ended up dropping the point. When in doubt, just submit it-you are not charged by the credit but by the project size. Let the Reviewer ask you a clarification, then you will get wiser in the end.
