SS Credit 5.1: Site Development—Protect or Restore Habitat
1 Point

Intent
To conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity.

Requirements
CASE 1. Greenfield Sites1
Limit all site disturbance to the following parameters:
--40 feet (12 meters) beyond the building perimeter and parking garages;
--10 feet (3 meters) beyond surface walkways, patios, surface parking and utilities less than 12 inches (30
centimeters) in diameter;
--15 feet (4.5 meters) beyond primary roadway curbs and main utility branch trenches;
--25 feet (8 meters) beyond constructed areas with permeable surfaces (such as pervious paving areas,
stormwater detention facilities and playing fields) that require additional staging areas to limit compaction
in the constructed area.
CASE 2. Previously Developed Areas or Graded Sites
Restore or protect a minimum of 50% of the site (excluding the building footprint) or 20% of the total site
area (including building footprint), whichever is greater, with native or adapted vegetation3. Projects earning
SS Credit 2. Development Density and Community Connectivity may include vegetated roof surface in this
calculation if the plants are native or adapted, provide habitat and promote biodiversity.
Projects with limited landscape opportunities may also donate offsite land in perpetuity, equal to 60% of the
previously developed area (including the building footprint), to a land trust within the same EPA Level III
Ecoregion identified for the project site. The land trust must adhere to the Land Trust Alliance ‘Land Trust
Standards and Practices’ 2004 Revision.

Potential Technologies & Strategies
Survey greenfield sites to identify site elements and adopt a master plan for developing the project site. Carefully site the building to minimize disruption to existing ecosystems, and design the building to minimize its footprint.Strategies include stacking the building program, tuck-under parking and sharing parking facilities with neighbors.Establish clearly marked construction boundaries to minimize disturbance of the existing site, and restore previously degraded areas to their natural state. For previously developed sites, use local and regional governmental agencies, consultants, educational facilities, and native plant societies as resources for the selection of appropriate native or adapted plants. Prohibit plants listed as invasive or noxious weed species. Once established, native/adapted plants require minimal or no irrigation, do not require active maintenance such as mowing or chemical inputs such as fertilizers, pesticides or herbicides, and provide habitat value and promote biodiversity through avoidance of monoculture plantings.

SS C5.1:场址开发—保护或恢复栖息地
1分

目的
保护现有自然区域，为推动多样性和物种栖息恢复被破坏的区域。

要求
情形1. 绿地场址1
按以下要求，限制所有场址扰动：
-- 超过建筑外沿界外40英尺(14米)；
--步道、院厅、地面车场、直径12英寸以上市政设施界外10英尺;
--干线道路、主要市政设施界外15英尺(5.2米);
--渗透地面（如透水铺装、雨水收集地、玩耍场地）等需要施工设施空间的界外25英尺(2.6
米)。
情形2. 已开发2 区域或定级的场址
保留或保护至少50%的场址面积(减去建筑楼基面积)，或者全部场址面积的20%，取面积较
大者，种植本地或训化植物3. 当在项目SS C2:开发密度得分时，种植屋面可纳入计算中，
但种植的是本地化或训化植物。

技术措施和策略
调查绿地场址确定场址中成分，制订场址开发的总体规划。合理设置建筑以最小化的减少对场址
中既有生态系统的干扰，建筑设计楼基面积要最小。策略有建筑叠合、地下停车、与邻居共享车
场。清晰地划分施工边界保护场址自然形态，恢复功能降低区域成自然状态。对已开发场址，咨
询政府机构、专业机构等选用种植合适的本地植物，禁用列明的入侵和有害植物。绿化考虑最
少的浇灌、或者无浇灌物种，避免依赖锄草、使用化学肥料、杀虫剂等维护，提供生物多样性的
栖息价值，避免单一植物物种。
