Hello everyone!

I am pretty new at LEED, and I am working on a building in urban areas that will earn SS credit 2. Credit Requirements specifies that "pedestrian-oriented hardscape areas can contribute to credit compliance. For such projects, a minimum of 25% of the open space counted must be vegetated." while LEEDUser Bird's eye view states that "25% of the required open space must be vegetated". It's not exactly the same thing for me. For example, let's say that I have a site area of 5 000 m2. I need to provide 20% of open space, so 1 000 m2. If the building site actually provide 2 000 m2 of open space, what is the actual area of vegetated space required? Is it 25% of the required 1 000 m2 or 25% or the counted 2 000 m2? It's not very clear for me, so thanks for your help!
