Sustainable Sites Credit 5.1: Site Development: Protect or Restore Habitat

 

Potential Technologies & Strategies

 

On greenfield sites, perform a site survey to identify site elements and adopt a master plan for the development of the peoject site. Carfully site the building to mnimize disruption to existing ecosystems and design the building to minimize its footprint. Strategies include stacking the building program, truck-under parking and sharing facilities with neighbors. Establish clearly marked construction boundaries to minimize disturbance of existing site and restore previously degraded areas to their natural state. For previously developed sites, utilize local and regional givernmental agencies,  consultants, educational faculities, and mative plant societies as resources for the selection of appropiate native or adapted lant materials. Prohibit plant materials lidted as invasive or noxious weed species. Native/adapted plants require minimal or no irrigation following establishment, 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 avoudance of monoculture plantings.
