Protect or Restore Habitat
Conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity.
On greenfield sites, limit all site disturbance to 40 feet beyond the building perimeter; 10 feet beyond surface walkways, patios, surface parking and utilities less than 12 inches in diameter; 15 feet beyond primary roadway curbs and main utility branch trenches; and 25 feet beyond constructed areas with permeable surfaces (such as pervious paving areas, stormwater detention facilitities and playing fields) tat require additional stafing areas in order to limit compaction in the constructed area.
Greenfield sites are those that are not previously developed or graded and remain in a natural state. Previously developed sites are those that previously contained buildingsings, roadways, parking lots, or were graded or altered by direct human activities.
On previously developed or graded sites, restore or protect a minimum of 50% of the site area (excluding the building footprint) with native or adapted vegetation. Native/adapted plants are plants indigenous to a locality or cultivars of native plants that are adapted to the local climate and are not considered invasive species or noxious weeds.
Projects earning SS Credit 2 and using vegetated roof surfaces may apply the vegetated roof surface to this calculation (if the plants meet the definition of native/adapted), in which case the requirement is 20% of the total site are (including building footprint). This option is intended for urban sites with little or no building setback (i.e. zero-lot-line).
