CASE 3 - pedestrian-oriented hardscape area & 25% vegetated area

Hi I have a question about this description: pedestrian-oriented hardscape areas can contribute to credit compliance. For such projects, a minimum of 25% of the open space counted must be vegetated. In this case pedestrian-oriented hardscape should be EQUAL to 20% of the project's site area and then minimum of 25% of the open space counted must be vegetated (even if I have more hardscape area I only count for LEED 20% of site area) OR I count total pedestrian-oriented hardscape on project site and then I try to achieve 25% vegetation? example: site area: 10 000 sf required pedestrian-oriented hardscape area: 10 000 * 0.2 = 2000 sf min. vegetated open space: 2000 * 0.25 = 500 sf or total pedestrian-oriented hardscape area on site: 5000 sf min. vegetated open space: 5000 * 0.25 = 1250 sf Thanks
