For projects that use pooled parking, calculate compliance using the project’s share of the pooled parking.
5% of the total parking spaces - Provide preferred parking for carpools after reductions are made from the base ratios. Preferred parking is not
required if no off-street parking is provided.
Mixed-use projects should determine the percentage reduction by first aggregating the parking amount of each use (as specified by the base
ratios) and then determining the percentage reduction from the aggregated parking amount.
Do not count parking spaces for fleet and inventory vehicles unless these vehicles are regularly used by employees for commuting as well as
business purpose
5% of all parking spaces used by the project as preferred parking for green vehicles. Green vehicles must achieve a minimum green score of 45

Human use. Views, adjacent transportation infrastructure, adjacent properties, construction materials with existing recycle or reuse potential.
Human health effects. Proximity of vulnerable populations, adjacent physical activity opportunities, proximity to major sources of air pollution.
The survey or assessment should demonstrate the relationships between the site features and topics listed above and how these features
influenced the project design; give the reasons for not addressing any of those topics.
Preserve and protect from all development and construction activity 40% of the greenfield area on the site (if such areas exist).
AND
Option 1. On-site Restoration
Using native or adapted vegetation, restore 30% (including the building footprint) of all portions of the site identified as previously developed.
Projects that achieve a density of 1.5 floor-area ratio may include vegetated roof surfaces in this calculation if the plants are native or adapted,
provide habitat, and promote biodiversity.
Restore all disturbed or compacted soils that will be revegetated within the project’s development footprint.
Project teams may exclude vegetated landscape areas that are constructed to accommodate rainwater infiltration from the vegetation and soils
requirements, provided all such rainwater infiltration areas are treated consistently with SS Credit Rainwater Management.
S
Dedicated athletic fields that are solely for athletic uses are exempted from the soil restoration criteria. These areas may not count toward the
minimum required area.
OR
Option 2. Financial Support
Provide financial support equivalent to at least $0.40 per square foot for the total site area (including the building footprint).
Financial support must be provided to a nationally or locally recognized land trust or conservation organization within the same EPA Level
III ecoregion or the project’s state (or within 100 miles of the project ). For U.S. projects, the land trust must be accredited by the Land Trust
Alliance.
Provide outdoor space greater than or equal to 30% of the total site area (including building footprint). A minimum of 25% of that outdoor space
must be vegetated (turf grass does not count as vegetation) or have overhead vegetated canopy.
The outdoor space must be physically accessible and be one or more of the following:
• a pedestrian-oriented paving or turf area with physical site elements that accommodate outdoor social activities;
• a recreation-oriented paving or turf area with physical site elements that encourage physical activity;
• a garden space with a diversity of vegetation types and species that provide opportunities for year-round visual interest;
• a garden space dedicated to community gardens or urban food production;
• preserved or created habitat that meets the criteria of SS Credit Site Development—Protect or Restore Habitat and also includes elements of
human interaction.
For projects that achieve a density of 1.5 floor-area ratio (FAR), and are physically accessible, extensive or intensive vegetated roofs can be
used toward the minimum 25% vegetation requirement, and qualifying roof-based physically accessible paving areas can be used toward credit
compliance.
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.
