SS Credit 5.2: Site Development: Maximize Open Space
1 Point
Intent
Provide a high ratio of open space to development footprint to
promote biodiversity.
Requirements
OPTION 1
Reduce the development footprint (defined as the total area of the
building footprint, hardscape, access roads
and parking) and/or provide vegetated open space within the project
boundary to exceed the local zoning’s open
space requirement for the site by 25%.
OR
OPTION 2
For areas with no local zoning requirements (e.g., some university
campuses, military bases), provide vegetated
open space area adjacent to the building that is equal to the
building footprint.
OR
OPTION 3
Where a zoning ordinance exists, but there is no requirement for
open space (zero), provide vegetated open space
equal to 20% of the project’s site area.
ALL OPTIONS:
- For projects located in urban areas that earn SS Credit 2,
vegetated roof areas can contribute to credit compliance.
- For projects located in urban areas that earn SS Credit 2,
pedestrian oriented hardscape areas can contribute
to credit compliance. For such projects, a minimum of 25% of the
open space counted must be vegetated.
- Wetlands or naturally designed ponds may count as open space if
the side slope gradients average 1:4 (vertical:
horizontal) or less and are vegetated.
Potential Technologies & Strategies
Perform a site survey to identify site elements and adopt a master
plan for development of the project site. Select
a suitable building location and design the building with a minimal
footprint to minimize site disruption.
Strategies include stacking the building program, tuck-under parking
and sharing facilities with neighbors to
maximize open space on the site.
