Slide 1

SW1 Presentation on Sustainable Sites Initiative The Sustainable Sites initiative is an effort to quantitatively describe the attributes of a sustainable site so that designers/ engineers can measure their success (or failure) in achieving the goals to maintain orimprove the predevelopment ecological integrity of a site. The Sustainable Sites Initiative currently addresses design issues associated with soils, hydrology, vegetation, material selection and human health. The initiative is designing specific measurable benchmarks associated with site selection; soils preservation, restoration, reuse and carbon sequestration; balancing the hydrologic cycle to reduce erosion and water use, provide flood mitigation, improve water quality, and recharge groundwater; using vegetation to provide specific benefits associated with heat reduction, air and water quality improvement, human health benefits, and habitat enhancement; materials selection to minimize embodied energy, toxins, and the waste stream; and using sites generally to decrease human health risks and promote human mental and physical health. Dr. Windhager's presentation will describe the Sustainable Sites Initiative and the efforts underway to implement the program and provide examples of potential metrics which may quantitatively describe a sustainable site, and how these metrics can be used to inform the design of a site.. As currently envisioned, implementation will create voluntary, market-based incentives to aid in climate protection, increase biodiversity, reduce pollution and other types of resource stewardship. Ultimately, the standards developed through Sustainable Sites will be integrated with existing voluntary building rating and credit systems. Ideally, these design concepts would become components of the LEED green building certification process. Steve Windhager, 1/24/2009

Beyond cost reductions, these


communities also experienced “real and significant” benefits, including aesthetic amenities, improved quality of life, improved habitat, and enhanced property values.
