Maximize Open Space

Intention:

1. A high open space to footprint ratio
2. Promote biodiversity

Implementation:

1. Case 1: there IS a local code for open space restriction
   • open space should exceed local code by 25%
2. Case 2: there is NO code (campuses or military bases)
   • open space is to be same size as building footprint
3. Case 3: there IS a local code, but ZERO open space requirement:
   • open space should be 20% of site area

• For all options:
  1. urban area projects that earn SS2
     • vegetated roof areas can count toward credit compliance
     • pedestrian oriented hardscape areas can count toward credit compliance (min. 25% open space must be vegetated)
     • Wetlands or naturally design ponds count if side slope gradients average 1:4 (vertical:horizontal) or less and are vegetated

Codes or Standards Applied:

1. none

Extra Credit:

• case 1: open space to exceed local codes by 50% (instead of 25%)
• case 2: open space to double building footprint (instead of match)
• case 3: open space to be 40% of site area (instead of 20%)

Submittal Phase:

• design
