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?
